Abstract: This blog presents a fully documented framework for DeFi solutions, such as “Automated Market Makers” (AMMs), on a highly scalable blockchain like the Partisia Blockchain. The framework guarantees fixed prices across independent liquidity pools and effectively addresses front-running with MPC.
Financial inclusion is at the heart of the original narrative that formed the beginning of blockchain and later Decentralized Finance (DeFi). The global financial crisis in and around 2008 revealed several weaknesses in traditional financial systems. The global financial crisis was part of the motivation behind the Bitcoin protocol creation. Although the challenges behind the global financial crisis were more significant than what immutable money could fix, it initiated and accelerated innovations that improved traditional finance and pushed to new horizons.
The very same crisis inspired the origin of Partisia. However, innovation was a different type of decentralized cryptography that was also designed to remove intermediates, which manage private information, such as sealed bids in financial markets. The initial work by Partisia was the world’s first Decentralized Exchange (DEX) with sealed bidding which went into commercial use in 2008.
The Partisia Blockchain established in 2020, is a combination and extension of these two narratives and provides a powerful encrypted computation network and tool set to continue fixing weaknesses in both Decentralized Finance (DeFi) and Centralized Finance (CeFi), as exemplified by the solution described in this blog.
DeFi is an important part of Web 3.0 and provides solutions that may most likely drive and enhance financial inclusion. This blog focuses on so-called Automated Market Makers (AMM) as a simple and decentralized way to exchange crypto assets. The core innovation behind AMMs is to conduct trading without direct interaction and matching of buyers or sellers of crypto assets. This significantly reduces the complexity of the market solution. Since the entire AMM solution is a set of smart contracts, the security model was also significantly improved as a genuinely decentralized trading platform.
Ethereum has been the most used blockchain platform for AMM solutions. And token bridges–as well as second layer blockchains–have broadened the uptake to other blockchain networks. Recent developments take this development one step further and run AMMs across independent blockchain platforms, i.e. cross-chain DeFi. This poses a set of new obstacles, such as the challenge of representing states (data and tokens) across independent blockchain platforms.
Another challenge preventing a simple copy-paste of the Ethereum model to sharded or cross-chain blockchains is the economics instilled into the Ethereum execution model. This is primarily the arbitrage opportunity coming from the “all or nothing” execution (atomic execution), as well as the sequential use of the entire AMM solution (one user at a time). With Uniswap (one of the most applied AMMs) for example, a user can swap asset A to asset B, and then swap asset B to asset C, and then potentially swap asset C back to asset A without other users interfering. Sometimes this set of swaps returns profit to the user. This type of arbitrage essentially for free since the public ledger allows anyone to constantly monitor the AMM solution. This is, however, only feasible due to the atomic execution and sequential use of the AMM solution, and cannot be transferred to a sharded blockchain or to cross-chain AMM solutions without additional economic mechanisms.
The Partisia Blockchain team has jointly worked with researchers specializing in AMMs and economic mechanism design. And together developed a mechanism which guarantees fixed prices as well as the “multi-swap” arbitrage opportunities described above. The key component is a “lock-swap” mechanism that guarantees a user fixed prices for a given swap. The mechanism only locks the actual requested trade and allows other users to use all liquidity pools without the non-scalable sequential use of the entire AMM solution as we know it from Ethereum.
The mechanism essentially works as follows: every pool keeps track of two pools, the “actual liquidity pool”, and a “virtual liquidity pool”. The actual liquidity pool keeps track of all the instant swaps, i.e. those that are actually executed. The virtual pool keeps track of the lock swaps, since such swaps might be canceled later on. Hence, by submitting a lock-swap the user secures fixed prices by the lock-swap function, which only affects the virtual liquidity pool. For any user after the lock-swap, the protocol ensures the smallest amount of assets across the actual liquidity pool and the virtual liquidity pool. Hereby, the mechanism favors first movers that fixed prices using the lock-swap function. Unlike the Ethereum sequential use, the lock-swap minimizes the impact on the entire AMM solution so assets can be exchanged in parallel and across independent blockchains and shards. And also in liquidity pools with one or more lock-swaps. Read more about the mechanism here.
In other words, the mechanism ensures the liquidity managed by the AMM solution is put to maximal use in two ways:
The mechanism is designed to fully utilize sharding where transactions are automatically off-loaded across different shards in an ideal way that favors unlimited parallelization, i.e. asynchronous and concurrent execution. This type of sharding is native to the Partisia Blockchain and will be instrumental in ensuring unlimited parallelization needed to match the demand as decentralization flourish. Read more about the sharding model here.
Finally, note that since cross-chain AMMs are similar in nature, the proposed mechanism also supports use of liquidity pools operated on completely separated blockchains.
Another challenge and obstacle for a broad uptake of AMM solutions within and beyond the blockchain ecosystem is front-running. On Ethereum and similar blockchain platforms, the AMM transactions are transparent to all, but added to the blockchain consensus model by one or more actors, such as “mempool operators” or “block producers”. The problem is that these actors can delay and place their own AMM valuable transaction, i.e. front-running.
Front-running is a critical problem that needs to be solved for the sake of the users, but also a problem that is critical for the DeFi narrative as a “single point of trust” failure. Fortunately, the advanced encrypted computation that is built-in to Partisia Blockchain provides a decentralized solution, which points back to the original work by Partisia and the first commercial use of MultiParty Computation (MPC) for safeguarding sealed bids.
However, as a big contrast to the first commercial use of MPC, Partisia Blockchain provides a simple interface that allows any developers (without cryptographic skills) to script the required computation and leave it to the network to compile and run the encrypted computations. The concrete solution is an encrypted computation which keeps the actual swap secret until it is fully executed. Hereby, the arbitrage opportunity from frontrunning is effectively addressed.
Ensuring that DeFi solutions comply with the jurisdictional regulation is, of course, an obligation for any DeFi service provider. It may also soon be a competitive advantage and a requirement for expanding the use of DeFi solutions outside of blockchain.
While financial fraud regulations, such as KYC and AML, are obvious, matters that are addressed in this blog may become essential regulatory requirements as well:
Although future regulatory requirements are unknown, building a blockchain network that is sufficiently flexible to quickly adjust to regulatory requirements may be crucial. For DeFi service providers that aim at offering DeFi solutions outside of the blockchain ecosystem and in direct competition with traditional financial solutions, regulatory requirements will be instrumental.

We are proud to introduce to the community one of our major roadmap items, the BYOC framework.
Interoperability and decentralization is one of our core values of our blockchain and one of our goals is to enable anyone to harness the capabilities of MPC. This is why our BYOC architecture was created in the first place, allowing the onboarding of any liquid assets to be usable as transaction fees (gas) on our blockchain.
Until now the foundation has proposed and enabled the onboarding of ETH, Polygon USDC and BNB as forms of payment. But our long term goal always was to allow for the community to make decisions on what tokens should be enabled on our chain.
The BYOC framework will now allow for the community to propose any tokens running on the Ethereum, BNB or Polygon chains to be usable as gas payment. The proposal then will go to our validators who will then make the final vote on whether or not to onboard the token as form of payment on Partisia Blockchain.
In the coming days we will share additional details and instructions on how the community can create a proposal for a token to be enabled on Partisia Blockchain. The foundation will initially start by submitting proposals to enable both USDT and MATIC tokens, and create detailed instruction guides using these two tokens as templates to help guide the community to onboard other tokens of their choice.
We are very excited to introduce this new feature and looking forward to seeing other great tokens being introduced by the community into our bridge.

As the significance of data privacy continues to grow, Partisia Blockchain remains at the forefront, pioneering technological solutions that enhance privacy, security, and adherence to regulatory standards.
Continuing our exploration of innovative developments, this month, we delved into Privacy Enhancing Technologies (PETs) and their impact on the blockchain landscape. At the core of any blockchain lies the concept of consensus without reliance on a central authority. Programmable blockchains have opened the door to a realm of possibilities, with applications categorized into three types: public input-public output, private input-public output, and private input-private output.
To provide a better understanding of the topic, we held a special MPC Advantages Q&A session, featuring Partisia Blockchain’s Principal Architect Emil Orloff, Cryptographic Scientist Anders Dalskov, and Head of Developer Relations Bruce Ahn. This insightful session delved into what MPC is, and how we differ from other privacy and MPC-based blockchains. To learn more about this topic and where Partisia Blockchain fits in, check out our blog post and comparison chart here.

When planning a supply chain from a logistics perspective, it is often useful to conduct a little thought experiment and think of yourself in the position of the products involved. In order to do this, you should “be the box” and trace each step you take from the factory to your customer, how much time you need to arrive and all of the steps you need to go through to get there. Let’s say you are a product, a piece of machinery made in a factory in Pennsylvania, United States. Post-production, you need to be packaged a certain way and the relevant paperwork prepared for export and import to the client’s destination, e.g., Germany. For this purpose, export and import documentation need to be prepared, product specification sheets, customs declaration forms, etc. Before “leaving” the factory you need to be packaged and the documentation needs to be prepared and added to the packaging. You are then picked up by a courier, who potentially needs a copy of certain documentation, and brought to a storage/sorting facility. You need to be marked clearly beforehand or afterwards in order to insure you are not confused with another piece of machinery. Then when ordered by a client, you may need to be re-packaged, for which the necessary documentation needs to be available to the courier before being shipped out. You are then picked up by a logistics company, either the same as the one the courier was from, or another one, and transported to where you will be exported. This is one of two places where all of the paperwork has to be in order, as customs officials now could inspect the paperwork and potentially block or delay your export. Customs declaration forms, material safety data sheets, shipment listings, the invoice to the client, etc., all need to be available and correct.
Congratulations, you have passed customs and are now in “international customs limbo”. After being “exported” you are usually transferred to a toll-free storage area and are then sorted into a container or loaded onto an airplane. When you do land, let’s say in Germany, the customs officials will want the same, or even different paperwork — perhaps even the same paperwork but in a slightly different format (I cannot emphasize enough how sensitive managing customs can be). VAT and other import taxes are (or are not) charged based on the required product declaration, which can sometimes differ greatly between countries, and the purpose of use. The product (you) is then released to a logistics company that sends you to your customer’s address. Hurray, you have arrived at your destination!
What this thought experiment shows us, is that during every single one of these steps, there are multiple touchpoints with many different people involved. Each one of these touchpoints represents a moment where a variety of things could go wrong. What if one of the documents falls off the package? What if one of the logistics employees accidentally confuses one of the packages during re-packing at the storage facility, or confuses the documentation? While logistics companies tend to have contingencies and redundancies, things sometimes go wrong causing unnecessary delays in supply chains and, in some cases, lost business.
Blockchain could be used to mitigate such logistics risks: a QR code representing a tokenization of a product could be added to each individual product package, in order to provide information on each individual product instantly and reduce the potential for confusion. Paperwork could be added to these product’s QR codes making them easily accessible to different parties along the supply chain and could also help in compiling different documents. If used correctly, a blockchain could also help keep track of shipments, both internally for logistics companies and externally for those managing supply chains. Sometimes shipments can be a bit like a black box and yes, sometimes products even get “lost”.
Furthermore, not only could documentation be made more accessible, but smart contracts could be created to streamline processes and e.g., create country-specific documentation automatically depending on where the product’s QR code is scanned. This could particularly come in handy if a product’s route is changed short notice, the product is checked by another country’s customs (e.g., another EU port of entry that wants things just ever so slightly differently) or the documentation required is changed at some point. The transparency provided by the blockchain could also make different actors such as customs authorities and/or logistics companies more accountable and provide a better basis for auditing/compliance. Furthermore, payment processes e.g., for VAT and other taxes, could potentially be automated, greatly increasing the speed of the customs clearing process.
The complexity of a supply chain increases with the added burden of quality assurance requirements, laid out by e.g., pharmaceutical GxP (Good practice, the “x” standing for a variety of different areas) regulations. Medical and pharmaceutical, food and cosmetic products require differing levels of traceability and quality assurance from the initial ingredients all the way to the patient. Each step in the production, testing, manufacturing, and distribution needs to be carefully and extensively documented and regarding logistics, the regulation laid out for e.g., pharmaceuticals is that of “Good Distribution Practice” (GDP). If you take the example of an agriculturally derived ingredient for a medicine, the process would be as follows:
A plant is harvested following (and documenting everything) according to Good Agricultural Practice (GAP) or Good Agricultural and Collection Practice (GACP) and then processed (e.g., the relevant ingredients extracted) according to Good Manufacturing Practice (GMP) and tested to Good Laboratory Practice (GLP). The product is then sent, of course following Good Distribution Practice (GDP), to the production facility, where it is further processed and combined with other ingredients to make a final product (under GMP) and then distributed to a pharmacy (again under GDP). Every individual production, testing and transportation step of each individual ingredient is meticulously documented and requires the ability to be audited by different parties as well as government entities. The idea being, that GxPs can assure two things for quality assurance quickly: 1) the assurance of quality of medical products on the market and 2) the ability to trace exactly where something went wrong in a pharmaceutical supply chain if there is some sort of defect. This all undoubtedly brings with it an immense amount of documentation, often in paper format, that needs to be stored for years by each individual party. Not exactly the most efficient way to store or audit a supply chain.
Both regarding the GxP traceability and less-regulated supply chains, blockchain technology could be used to reduce errors, streamline processes, facilitate documentation availability, and allow for better traceability and auditability for all parties involved. However, companies have legitimate reasons not to want to reveal certain information about their supply chains. A pharmaceutical company for example may not want to reveal the source of their ingredients, as a competitor may use that information to their advantage. This is where MPC could come in and be used to obfuscate certain sensitive information about the supply chain. Moreover, necessary documentation could only be made available to certain parties, such as customs authorities.
An MPC-blockchain solution built on Partisia Blockchain for logistics and quality assurance could look as follows: each step set out by GxP could be documented and listed on the blockchain, while only making the source of each documentation available to the parties necessary (e.g., a regulatory body of a manufacturing company). Each package shipped could be traced transparently by the customer, with a smart contract automatically generating documentation for each individual step in the supply chain and customs touchpoint. All of this can be done without revealing too much information to parties that do not need to have the full picture. Such a system could reduce errors, increase efficiency, allow for better auditability and more transparency of supply chains — while MPC keeps valuable trade secrets private.
Partisia Blockchain is dedicated to facilitating innovative solutions to real-life problems. Better supply chain and quality assurance are two of these problems.

In today’s context, the healthcare sector by itself contributes to around 30% of the global data volume, while the pharmaceutical industry significantly adds to this data generation. Handling and utilizing data from these sectors are also subject to some of the strictest regulations due to the nature of data that often includes personally identifiable information. GDPR, internal policies, and other regulatory frameworks pose tough challenges when data is collected or shared beyond isolated data silos for analytical purposes.
Public and private blockchains serve as effective tools for maintaining an immutable and transparent log of transactions, which can be relied upon and examined by various stakeholders such as public authorities. However, when it comes to the actual manipulation and processing data, both public permissionless blockchains and private blockchains are insufficient due to the lack of privacy features. This is where Partisia Blockchains’ distinctive and proprietary secure multiparty computation (MPC) technology emerges as exceptionally valuable
Our MPC technology empowers individuals and organizations to preserve privacy right from the input stage. This entails breaking down data into many encrypted secrets, which are then shared with specialized MPC network nodes. Critically, these nodes remain unaware of the specific content they store or compute on. Predetermined private and public smart contracts establish protocols for computations and determine access privileges to the outcomes, as authorized by permissions.
The potential applications for private computations within the healthcare and pharmaceutical sectors are virtually limitless. In this article, we will explore some of the extensively discussed scenarios.
Privacy technologies play a pivotal role in enhancing the security and confidentiality of private DNA sequencing. With the advancements of genetic analysis techniques, individuals are increasingly seeking to unlock insights from their genomic data, but the sensitive nature of genetic information demands robust measures to preserve privacy. MPC offers solutions by enabling private computations on encrypted genetic data without the need to expose the raw data. This allows for collaborative research, personalized medical insights, and genetic advancements while ensuring that individuals retain control over their sensitive genetic details.
By employing these technologies, private DNA sequencing initiatives can preserve privacy, encourage data sharing for scientific progress, and mitigate the risks associated with unauthorized access or breaches of genetic information.
Traditional data sharing approaches often raise concerns about privacy breaches and data ownership when it comes to the almost abundant amount of sensitive patient information and proprietary research data for healthcare and pharmaceuticals. MPC addresses these challenges by allowing multiple parties to jointly analyze and derive insights from their respective datasets without actually revealing the raw data to each other, but only share valuable outputs.
In the context of clinical research, pharmaceutical companies and healthcare institutions can collaboratively conduct analyses on aggregated datasets while keeping individual patient information and proprietary data secret. This facilitates cross-institutional research without the need to centrally consolidate data, eliminating the risks of data exposure and unauthorized access. Different pharmaceutical companies, each possessing valuable proprietary data, can engage in joint studies without revealing their confidential insights.
This collaborative approach unlocks opportunities for discovering broader trends, identifying potential drug interactions, and conducting large-scale analyses that draw from diverse datasets. By preserving privacy and ownership, MPC encourages cooperation among entities that might have otherwise hesitated due to privacy concerns. In essence, MPC bridges the gap between robust data-driven insights and the need for privacy, fostering a new era of collaborative clinical research across previously isolated data silos and organizations.
MPC offers robust primitives to revolutionize supply chain management within the pharmaceutical and healthcare industries. In these sectors, ensuring the integrity, transparency, and security of the supply chain is of all importance, as any inefficiencies or vulnerabilities can have serious consequences for patient safety and product quality.
MPC provides a solution by enabling various stakeholders, including manufacturers, distributors, regulatory bodies, and even healthcare providers, to collaboratively manage the supply chain without revealing sensitive proprietary information to one another. This is particularly valuable when dealing with complex global supply networks involving multiple parties, each with their own data and interests. Parties can jointly verify and validate critical supply chain information, such as the authenticity of raw materials, production processes, transportation routes, and inventory levels.
For example, pharmaceutical companies can verify the authenticity and quality of raw materials supplied by third-party vendors without sharing their precise formulation details. Regulatory agencies can conduct audits and ensure compliance across the supply chain while preserving the confidentiality of manufacturing processes. Healthcare providers can track the provenance of medical devices or drugs to enhance patient safety and prevent counterfeiting.
MPC-driven supply chain management ensures trust among stakeholders by providing a secure environment for collaboration. It prevents fraud, minimizes the risk of data breaches, and streamlines information sharing. By harnessing the power of MPC, the pharmaceutical and healthcare industries can establish a more efficient, transparent, and secure supply chain ecosystem that ultimately benefits patients, regulatory compliance, and business operations alike.
MPC presents a transformative way for streamlining the recruitment process in clinical trials while upholding patient privacy and data security. Clinical trial recruitment often entails the sharing of sensitive patient information across multiple stakeholders, including healthcare providers, research institutions, and pharmaceutical companies. MPC offers an innovative approach by allowing these entities to collaboratively identify eligible participants without revealing individual patient details.
Using MPC, each participant contributes encrypted data, maintaining the confidentiality of their personal information. The parties can collectively perform computations on this encrypted data to match potential participants with specific trial criteria, such as medical history, demographic characteristics, or genetic markers. This process ensures that no party gains access to the raw data of others, mitigating privacy concerns.
MPC technology not only accelerates the participant matching process but also encourages broader collaboration among stakeholders who might otherwise hesitate to share sensitive patient data. This approach streamlines the recruitment process, reduces administrative burden, and respects patients’ privacy rights. Ultimately, MPC revolutionizes clinical trial recruitment by combining efficiency and data security, fostering trust among stakeholders and contributing to the advancement of medical research.

Changing the data market business model from buying and selling of your data to buying and selling the “use” of your data.
Current advertising data market industry involves selling and buying of data. Regardless of the type of data the advertisers are looking for, it’s all about collecting the data from various means, categorizing it, perhaps pseudo anonymizing it and selling the data to advertisers. And data, as it turns out, is a very lucrative business. The global market size of the advertising market is estimated to be US$600–800 billion and the internet makes up about half of that size.
You probably have heard this statement before. If it is free, you are probably the product being sold. And this is a very common way for the data market players to create a “free” application that allows the collection of data that the market players will buy and sell. The more accurate the data, the more valuable. Google, Facebook, Twitter, Microsoft, etc all use similar business models. But there are other players in this market, some you may have heard of in the news (Cambridge Analytics for example) or smaller companies that trade your data under the covers. They will collect from various sources, reshuffle, and resell the data to others.
But as with any business model, there are challenges and the data market is not without its share of issues.
Partisia Blockchain’s privacy first blockchain with research lead secure multiparty computation (sMPC) can help solve these issues and also provide data market participants with alternate business models that can bridge the gap between consumer privacy concerns and better data overall.
This changes the data market business model from buying and selling of your data to buying and selling the use of your data. By shifting the paradigm to a services model, new potential revenue streams become available while being able to solve some of the difficult challenges facing the advertising industry.
Projects like Blockchain-Ads and Kin are already looking to take advantage of this new model and we are exited to see where this will lead in the future.
Connect with us at build@partisiablockchain.com to see how we can help you create new business models, solve challenges and provide new incentives for the users to use your system.

Throughout the ages, famous philosophers have grappled with the concept of good governance. From Aristotle, Machiavelli, and Hobbes to Rousseau, Voltaire and Rawls, different perspectives have existed and challenged each other over the ages on the topic. Today, in democratic societies at least, the general consensus is that of a government that is accountable to the people, with checks and balances, the guarantees of fundamental rights, and integrity in how it operates. New technologies, such as blockchain, can aid in the pursuit of good governance — this article outlines a few possible examples of how Partisia Blockchain could help governments innovate and better their governance practices:
Paperwork, licenses and standing in lines — bureaucracy is something that regardless of political affiliation, people love to hate. But the true purpose of bureaucracy (whether well-designed or not) is to ensure due process and guarantee people’s rights. This in essence very noble pursuit can run into a variety of different problems, from potential inefficiency to outright corruption. A public blockchain could help to streamline processes and make them more transparent, paperwork can be filed and traced through different steps on the blockchain, whereas combined with MPC the private information in these processes can be kept secret, or only available to certain parties. In certain countries, where corruption is an issue, the intransparency of bureaucracies can allow for wrongdoing in e.g. bureaucratic processes such as ignoring, changing and/or the outright fabrication of documents. A public blockchain could allow for more trust in bureaucratic institutions, especially if those institutions don’t have control over the nodes that operate the blockchain. This is the principle behind a project called DelNorte.
DelNorte is currently running pilot projects in Latin America creating NFTs out of real estate deeds and adding them to a public blockchain. This is meant to make the bureaucratic process more efficient, give more stability and transparency regarding real estate ownership in the participating countries, circumvent potential corruption and maintain the integrity of the institution. While the government is the door to access to the system, the government does not have control over the blockchain and the listed real estate deed NFTs. Partisia Blockchain is proud to have entered into a partnership with DelNorte, helping them to add privacy and security to their e-government solutions.
Governments provide goods and services to their citizens, from parks, highways and schools to militaries for the national defense. While some governments have more resources than others, many of the goods used to e.g., build and maintain a public highway, need to be contracted to third parties. What is usually the case when a government has to contract such goods or services out, is that they publish a tender for which parties can bid. This ideally leads to many different companies bidding for the contract with the government, attempting to underbid each other and/or outclass each other with the quality of the good/service that they provide.
Nonetheless, public procurement bidding processes are often highly intransparent and even prone to corruption, which cheat the taxpayers out of the best possible deal they could have had. Blockchain technology could also help combat this problem, making the bidding process transparent and establishing trust with the general public. However, a major issue with the transparency of a public blockchain is that it does not allow for the hiding of certain sensitive information e.g., a company’s capabilities, classified technology, etc. that could be part of the bidding process. This is where E-Trusty comes in: E-Trusty is a dApp building on Partisia Blockchain to use the public blockchain to create transparency, while obfuscating sensitive information in the bidding process using MPC. The goal is to create a platform for public procurement that allows for the transparency of seeing multiple bids for a given contract, while using MPC to hide and protect sensitive information.
Multiple central banks around the world are beginning to develop and implement so-called central bank digital currencies (CBDCs). As opposed to digital currencies, such as Bitcoin or Ethereum, these digital currencies are centralized and issued by a national bank. They are pegged to the value of a fiat currency and are meant to be a part of the existing financial system. There is however a major concern regarding CBDCs and that is that due to their centralized structure and control, they could essentially allow for a central bank, and by extension a government, to have complete insight into how people are spending their digital money. Furthermore, it is also feasible to imagine that a government could easily overreach, especially if it were to become corrupt, and easily seize such digital money. There would therefore need to be checks and balances guaranteed in the application of a CBDC. One solution for this problem, could be to use MPC to make the settlements of such a CBDC private. Such a system could also be designed to allow for certain transparency towards a government entity with the sufficient legal justification such as a warrant. The CBDCs settlements would be intransparent to e.g. the national bank or the government, however a court could allow for access to certain transaction data for a judicial institution.
In many places across the world, trust in elections is waning: the intransparency of voting systems, combined with distrust fueled by political rhetoric are a major threat to the integrity of democracies today. The recent coup in Bolivia or the storming of the U.S. Capitol have shown that even an unsubstantiated claim of fraud in an election can lead to political violence or even the overturning of a democratically elected government. E-voting, and particularly blockchain-based e-voting solutions, have attempted to solve this issue. They have however run into a variety of problems: intransparency or too much transparency, hardware and/or software vulnerabilities, among many others. Nonetheless, Partisia Blockchain’s MPC technology could help in solving many of these issues. MPC could be used to assure the privacy of a voter’s ballot, while showing votes being tallied for specific candidates in real-time. The election results could be publicly auditable and contestable and voters could be able to track their own votes. This kind of solution could in theory ensure safe, transparent and auditable elections, while keeping people’s votes secret.
Partisia Blockchain Foundation is dedicated to facilitating innovative solutions to real-life problems. Democratic innovation is one of the fields we are proud to contribute to.

During the course of July, students, young professionals, academics, and industry leaders came together from across the globe for the SDG Summer School. This Summer School is organized by the University of Geneva and hosted in the SDG Innovation Lab, close to the United Nations as well as on different campuses around the world in parallel. Partisia Blockchain had the privilege of attending and actively participating in the program.
Groups of students were formed, assigned a coach and began to develop an idea into a project. The projects were all aimed at solving pressing problems and contributing to the Sustainable Development Goals (SDGs). After three weeks the groups pitched their projects to a jury consisting of decision makers from major institutions such as the University of Geneva, the Global Fund and the Olympic Committee.
I had the opportunity of representing Partisia Blockchain and coaching a group of students in creating an innovative solution to women’s health:
“Her Menstrual Trials” is an application using MPC and Blockchain to track women’s health trends and the effects of medications without revealing anyone’s personal health data. The blockchain would provide crypto-incentives to the participants and help store and track the data collected, while MPC would keep the data private, while allowing for real-time, continuous data collection from the participants.
Furthermore, Partisia Blockchain had the pleasure of sponsoring a student from Copenhagen to come to Geneva and participate in the Summer School.
The SDG Summer School is an impactful event empowering young minds to find solutions to the most pressing problems around the world. Partisia Blockchain is proud to support such an initiative and help to contribute to a brighter future for all.

In 2018, the European Union’s General Data Protection Regulation (GDPR) came into effect, causing a wave of changes to terms and conditions in your favorite applications across the globe. GDPR aims to increase people’s control and rights over their own personal information and heavily penalizes companies that infringe on these rights. Infringing on the rights of EU citizens laid out in GDPR could result in a fine of €20 million or 4% of the annual global turnover of an enterprise, so compliance is strongly incentivized. This new regulation is widely considered a major turning point in data protection and privacy rights, starting a policy diffusion of similar data protection laws across the globe. GDPR is law in every member country of the European Union and establishes a “single data market” within the EEA. Similar regulations have also been adopted in California, Chile, Japan, South Africa, Argentina, Turkey and Brazil, among others.
GDPR (as well as many of the similar regulations) involves multiple core tenets, among others setting out the principles for which personal data can be used and processed. Lawful purposes of the use of personal data and the digital rights that citizens have over their personal data. While there are many different compliance aspects of data protection regulations, such as GDPR, here are a few examples of how our technology could help your organization stay compliant:
GDPR requires organizations processing personal data to transform the data in such a way that it cannot be connected to the person it was collected from (pseudonymization). Partisia Blockchain could help an enterprise disassociate a person from their (encrypted) data, assuring such pseudonymization through the use of multiparty computation (MPC) technology. This pseudonymization can also be done in a way to allow for continuous collection of data from the same individual, if required for e.g. a longer-term study.
Furthermore, the concept of MPC also can also aid in maintaining an individual’s control over their data, as e.g. the concept of MPC secret sharing can allow for useful outputs being generated without compromising the underlying data (see Multiparty computation: The beacon of privacy solutions explained). MPC (especially combined with a blockchain) can also therefore increase the security of personal data, as the data and calculations are all run in a decentralized fashion by nodes that are all independent from each other. Partisia Blockchain’s nodes and their operators are all independent, run independent systems and have been vetted for cybersecurity by Partisia Blockchain experts.
Another right laid out by GDPR is the so-called right of access. This is the right of people to be able to see how their data is being processed and with whom it is being shared. The ledger kept on a blockchain could help an organization provide an immutable record to ensure this right. For the same reason, the blockchain could help organizations provide the record of processing activities required for GDPR-compliance under certain circumstances as well. As opposed to some other blockchains, Partisia Blockchain also allows for the possibility of private data to be removed from the record. Essentially meaning that data entered into the blockchain can be erased later on, allowing for compliance with GDPR’s right of erasure (the right for people to have their personal data removed from a database).
Lastly, the geographical location of servers used to process personal data could sometimes mean the difference between compliance and a criminal offense. Partisia Blockchain’s jurisdiction management v1.0 allows organizations’ developers to specify the geographic location of nodes to be used in calculating personal data. This could for example allow for private data from the EU to only be sent to EU-based nodes, ensuring that the integrity of the single data market and the data rights of EU-citizens are not breached.
Partisia Blockchain is committed to empowering others in solving real-world problems using our cutting-edge technology. Data rights and data privacy challenges are two of these problems.

The point of this document is to provide the shortest (and most intuitive) possible introduction to each of the technologies mentioned in the title. I hope I succeed in this endeavor.
The technologies in this document all — with exception of differential privacy — deal with “secure” computation on data. At a very high level, this means they can be used to perform an arbitrary computation on one or more pieces of data, while keeping this data private.
Secure multiparty computation, which is what we do here at Partisia, is the term for a fairly broad class of protocols that enable two separate entities (called parties) to compute a function, while revealing nothing except the output.
An MPC protocol typically proceeds in three phases: First the inputters secret-share their private inputs. This step can be thought of as each user sending a special type of encryption of their inputs to the nodes doing the computation. The encryption ensures, for example, that at least two out of three nodes are required to recover the input, and thus, we get a security model that relies on non-collusion. It could also be the case that all three nodes must collude to recover the input — in this case, we have a full threshold model (since all servers must collude to break privacy).
The next step involves the nodes (the servers A, B, and C) performing the computation on the encryptions (i.e., secret-shares) received in the input step.
When the nodes finish the computation, they will hold a secret-sharing of the output. Each node’s share is returned to the users, so they can recover the actual output.
As might be inferred from the figures above, MPC works particularly well if the computation nodes are well-connected. Indeed, what makes MPC expensive to run is all the data that the nodes have to send between each other.
MPC have been actively studied in academia since the early 1980s and there are a lot of good resources available to learn more about it:
Fully homomorphic encryption (FHE) solves a very old problem: Can I have my data encrypted and compute on it too? FHE is a tool that allows us to not only store data encrypted on a server, but which allows the server to compute on it as well, without having to decrypt it at any point.
A user encrypts their private data and uploads it to a server. However, unlike a traditional E2EE (End-to-End-Encrypted) scenario, the server can actually perform a computation on the user’s private data — directly on ciphertext. The result can then be decrypted by the user using their private key.
FHE, unlike MPC, relies on clever cryptographic computation, rather than clever cryptographic protocols. On the one hand, this means FHE requires less data to be sent between the server and client compared to MPC. On the other hand, FHE requires a lot of computation to be done by the server.
Practically speaking, FHE is slower than MPC (unless we have an incredibly slow network, or incredibly powerful computers).
Practical FHE is a relatively new technology that only came about in 2009. However, since then it has received quite a bit of interest, especially from “bigger” players like Microsoft or IBM.
Partisia Blockchain supports FHE solutions.
While both MPC and FHE allow us to compute anything, zero-knowledge proof (ZKP) systems allow us to compute proofs. In short, ZKP allows us to compute functions where the output is either “true” or “false”.
ZKPs are incredibly popular in the blockchain space, mainly for their role in “rollups”. The particular type of ZKPs used for rollups are ZK-SNARKs, which are succinct proofs. In a nutshell, a succinct proof is a proof whose size is some fixed (small) constant, and where verification is fast. This makes smart particularly useful for blockchains since the proof and verification are both onchain.
That said, ZK rollups don’t actually use the zero-knowledge property — they only use the soundness and succinctness properties of the proof scheme.
Soundness simply means that it is very difficult to construct a proof that appears valid, but in actuality is not.
ZKPs, like FHE, takes place between a single user and a verifier. The user has a secret and they wish to convince the verifier about some fact concerning this secret, without revealing the secret. ZKPs don’t designate a particular verifier, so anyone can usually check that a proof is correct.
The final private computation technology I will talk about here is trusted execution environments. A trusted execution environment, or TEE, is basically just a piece of hardware that is trusted to do the right thing. If we trust this particular type of hardware, then private computing is clearly doable.
TEEs, being hardware, are tightly connected to some hardware vendor. Often when TEEs are mentioned, what is really meant is something like Intel’s SGX or ARM TrustZone. SGX is the TEE used by Secret Network, for example.
The security model of TEEs is fairly different compared to the other technologies I have written about so far, in that it is a lot more opaque. Vulnerabilities have been demonstrated in different iterations of different TEE products, especially SGX.
Differential privacy is radically different from the previous technologies. (In this discussion I will exclude ZKPs since it does not allow general computations.)
While MPC, TEE and FHE all provide means of computing something on private data, they do not really care about what that something is.
For example, it is possible (albeit pointless) to compute the identity function using both MPC, TEE and FHE.
This is because MPC, TEE and FHE allow us to compute anything. In particular, they allow us to perform computations that are not really private.
At this point, we may ask: Well, why would we perform such a silly computation on private data? For some computations, it might be easy to see that it is not private (in the sense that the original input can easily be inferred from the output). However, there are many computations that are seemingly private, but which can also leak the input if we are not careful. For example, it has been shown that it is possible to extract machine learning models, simply by querying a prediction API. In another example it was shown that it is possible to extract the data that a model was trained on.
These issues all arise because there are no restrictions on the computation that is performed. Differential privacy tries to fix this.
Differential privacy is used to provide a fairly intuitive guarantee. Suppose we are given two databases A and B. The only difference between these two databases, is that a particular entry R exists in A but not in B. Differential privacy now states that, no matter which type of query we make on the database, we will not be able to guess whether we are interacting with A or B.
Naturally, this means that some queries cannot be allowed. For example, it is not possible to obtain differential privacy if one can simply ask “Is record R in the database?”. Generally, differential privacy is obtained by adding noise, or synthetic data, to the database as well as restricting the type of queries that are allowed.
What makes differential privacy different from MPC, TEE and FHE, is that differential privacy makes guarantees about the output of a computation, whereas MPC, TEE and FHE makes guarantees about the process of arriving at that output. In summary:
This also means that differential privacy is not in direct “competition” with MPC, TEE or FHE, but rather complements them.
While each technology has its specific advantages and use cases, it is our feeling that Partisia Blockchain’s MPC, backed by 35 years of research and practical implementation does seem to provide the most overall coverage of all possible scenarios with very little drawback.

A blockchain, at its very core, is a way for everyone to agree on what the current state of the world is, without having to rely on a trusted authority.
Of course, by “everyone” we don’t actually mean everyone, but instead everyone who believes in the security model. Likewise, by “the world” we also don’t actually mean the world, but rather, whatever is currently written on the blockchain’s ledger. Nevertheless, well-known blockchains such as bitcoin or ethereum both have market caps in the 100s of billions of USD, which tells us that the technology excites people.
Programmable blockchains, in particular, are exciting because their “world” is very rich. On a programmable blockchain, the “world” is basically the current memory of a computer, and so, simply by being clever about how we design the programs that run on this computer, we can use it to accomplish almost anything.
Let’s digress for a bit and classify programs into three categories:
— Those that take a public input and produce a public output
— Those that take a private input and produce a public output
— Those that take a private input and produce a private output
A programmable blockchain such Ethereum supports programs of the first kind: Everyone sees what goes into a smart contract on Ethereum, and everyone sees what comes out again. This is great for some applications (like agreeing on who bought a NFT), but clearly not sufficient for others (like performing an auction).
Several solutions have surfaced which attempt to support the remaining two types of computations. Let’s take a brief look at some of them:
Zero-knowledge proofs (ZKPs) are, in a nutshell, a way for someone to convince (i.e., prove to) someone that they know or possess something, without revealing anything about that something. One situation where this shows up, is when someone wishes to prove to someone else that they control a certain amount of tokens.
ZKPs can therefore be used for private-public and private-private computation, to a limited degree. ZKPs can only compute, well, proofs. This in particular means that the computations are limited to a binary “yes” or “no” output. Moreover, ZKPs are inherently single-user oriented, so it is not possible to perform a computation that takes multiple private inputs.
Note that a program that takes a public input, but produces a private input does not make sense. If everyone can see the program and what goes into it, then everyone can obviously see the output as well.
Another private computation technique is fully homomorphic encryption, or FHE as it is called for short. At its very basic, FHE is a way of encrypting data such that it is possible to perform computations directly on the encryption.
This immediately tells us that FHE for sure supports private input private output type computations.
However, FHE, like ZKPs, are oriented towards a single user scenario. This means that, although FHE can perform any computation (which ZKPs cannot do), they cannot perform a computation that receives private inputs from multiple users.
In contrast to the two above technologies (as well as the next one), trusted execution environments (shortened as TEEs) are a purely hardware based solution to the private computing problem we’re looking at.
A TEE is simply a piece of hardware that have been hardened in certain ways that make it hard to break into. If we believe this to be the case, then a TEE can be used to perform the private input, public/private output computations we’re interested in.
Inputs are encrypted using a key stored only on the TEE, and computations take place on the TEE after decryption. When the computation is done, the output is encrypted (or not, depending on whether the output should be public or private) and then output by the TEE. In this way.
TEEs therefore clearly support the type of single-private-input computations talked about so far. However, the situation is a bit complicated if we want to receive inputs from multiple sources. Indeed, the only way that can be possible, is to make sure the same key is stored on everyone’s TEE.
The last tech I will look at is secure multiparty computation, or MPC. This privacy tech supports both types of computations, just like FHE and ZKPs, but where it distinguishes itself is that it naturally supports private inputs from multiple sources. Indeed, there’s a reason it’s called secure multiparty computation.
This makes MPC especially suited for a blockchain because of its multi-user nature.
The above categorization leaves out a lot of details, since it talked about neither the security models that each of the technologies use, nor about their efficiency.
Each of the four technologies above operate in a particular security model, and none of the models are exactly the same. Likewise, they each have some properties that make them desirable compared to the others. (For example, FHE requires more computation, but less communication, than MPC.)
In general, MPC does seem to come out on top, and is the only technology that easily supports computations where multiple users provide inputs. MPC, by its nature, is a decentralized technology, which is probably why it works so well in a blockchain setting. That being said, an ideal world would probably use all of the technologies in a carefully created orchestration to ensure the best guarantees in terms of both security and efficiency.

Self-sovereign identity (SSI) is an ever increasingly important concept to enable users control over their own data and let them share it with whom they want. Today, data rests in centralized databases that belong to big enterprises with little transparency into how the data is actually being used and for what purpose.
SSI turns this around and data starts with the users, actually resting at users own device at first. Then it is up to the users to choose with whom and what data they share. Additionally, privacy-preserving features, such as selective disclosure and predicates enhance the user to share data without sharing it all or just prove simple facts about the data.
There are many great tools and infrastructures that can handle SSI, and Partisia Blockchain’s MPC technology adds a new component to the stack that enables new business models, enhances privacy for the data-driven economy, and will take your project ahead of the competition. So read on if you are a builder of the US$27 billion global digital identity market that is expected to expand at a CAGR of 17.2% from 2023 to 2030.
First things first, digital identity usually revolves around three actors: issuer, holder, and verifier.
The issuer issues verifiable credentials to the holder, and the holder can then present the credentials to a verifier who can verify the content by digital signatures and Decentralized Identifiers (DIDs) that may be on a blockchain. For most digital identity use cases, DIDs and associated DID documents are the only elements that get on the blockchain. We do not take a deep dive on this in this article.
DIDs and verifiable credentials are some of the essential components that make up digital identity, especially digital identity that works with decentralized networks. DIDs are a type of address that is generated to manage digital signatures, and verifiable credentials are credentials created and issued by any issuer based on their DIDs.
To enable real SSI, the users will have to store all data themselves at first, often in digital identity wallets, and only then will the user be in full control. The data itself can be data inputs from users such as personal Identifiable Information (PII) or digital verifiable credentials issued by a third-party, e.g. KYC provider issues KYC claim as digital verifiable credential. Credentials are often issued and exchanged by an agency that establishes secure peer wise connections.
Multiparty computation (MPC) is a groundbreaking technology that allows multiple data inputs to remain private while still being computed on and only sharing the outputs. The computing itself is carried out by specially selected MPC validator nodes who each compute on secret shares of the data and privacy is guaranteed by cryptography.
Compared to ZK proofs, such as zk-SNARKs, MPC is a game changer that allows computing on any function. This takes digital identity to the next level because it is now not only possible to share data with privacy features, but also carry out decentralized computation on private data and write business logic into private and public smart contracts to orchestrate the process and rules.
As we learned before, ZK proofs are good for simple presentations about specific data, e.g. a verifiable credential issued by an employer can be used to prove to the bank that you earn more than US$80,000 a year to qualify for a loan without revealing the exact amount you earn.
Now imagine that we need to compute statistics on multiple inputs from multiple users and compare a single person’s salary to the average, all while preserving privacy. ZK proofs cannot handle general computations on multiple inputs and comparison is limited to two users presenting against each other, so another system would have to support it. This is where Partisia Blockchain’s MPC comes to save the day! MPC on Partisia Blockchain can handle multiple inputs and preserve the privacy while carrying out efficient general computation.
Even though all smart contracts and data can be private, it is often worth considering only to push the most sensitive data and operations into private computation because it is generally more expensive than public computation. This goes for all ZK technology. For instance, if you want to calculate the average salary of employees, you might consider just the salary as private inputs plus pseudonymized identity, and then do statistical calculations in the public space.
When we look at DID/SSI solutions, the business requirements of the implementation usually go past simple verification of ID. DID/SSI proof is just the first step. The real challenge is what other data do you need after the verification. Perhaps it is to verify that this person has proper credentials for accessing a system. Or another popular use case for DID is to verify a user has enough assets to pay for something without revealing their total asset holding. Another app that is looking to build on our system is trying to create a persona on-chain, which advertisers can target, without revealing personal information about the user themselves.
In all these use cases, a simple proof system becomes too expensive and slow due to the fact that each individual parameter must require a proof. When you have 10 users, maybe this is possible. But what happens when you need to scale to 1000 or 10,000 users? And proofs are not computations. It is unable to compute the various different private data for analysis.
This is where MPC can extend the functionality of DID/SSI to create multi-functional applications. Through MPC you can both prove and compute multiple parameters in a single computation and include all the additional business requirements while keeping the data private.
During the pandemic, many attempts were made to create a Covid-19 passport so citizens could prove they were either vaccinated or tested negative while preserving privacy. Zk proofs are good for this, but limited to only presenting yes/no results to a verifier without extensive physical verification such as ID cards, which would compromise SSI principles.
In collaboration with HES-SO Valais-Wallis, Partisia Blockchain developed a solution where identification is reduced to matching an individual’s face with an image of the person’s face powered by MPC in order to increase security and privacy. The Partisia Blockchain ensures trustworthy information is broadcasted to the verifier and MPC ensures that the private information about the citizen is used only for matching and kept hidden for the verifier.

Thanks to EthCC for providing a valuable platform for us to showcase our innovative technology, enabling secure collaboration while preserving privacy through advanced Multiparty Computation (MPC). We hope to see more of you next year.
As adoption is one of the main focuses for us, we kicked off a new adoptions team creation with a meeting in Aarhus. All the adoption officers were brought together to align on our strategy and goals for this year. Some of the key areas we agreed to focus on were in metrics, (number of leads from various sources, percentage of conversion, effective marketing campaigns, etc) to understand better where we are doing well and where we need to improve on.
Talking about adoptions, we are also happy to introduce another amazing project that has signed on to build on Partisia Blockchain. Veric is a credential and asset oracle running on Harmony One and they will begin to integrate Partisia Blockchain’s privacy technology to add additional functionality to their application. By adding the privacy layer, they aim to privatize details of their assets that they are looking to use for payment.
We were also honored to participate in this year’s University of Geneva “SDG Summer School”. The focus this year was “Open Source Health Solutions” and students from across the world met during three weeks on the ground and online. We had the pleasure of coaching a group of young minds looking to solve a technological problem for a healthcare company. The innovative solution the students came up with uses MPC and blockchain technologies and could have a positive impact on women’s health.
In line with our Ecosystem Focus, we were excited to showcase SecondLane, a groundbreaking project co-founded by key players in the Web3 OTC market. Offering advanced technology and licensing expertise, SecondLane is building on Weezi empowers project teams, advisors, and investors to unlock liquidity for unvested tokens and equity, while also facilitating the discovery and trading of illiquid digital assets.

Partisia Blockchain Foundation is happy to announce our grants program for the second half of 2023. We are giving out up to 3 million $MPC tokens (valued at US$1.2 million from last years public sale price of 40¢ a token) to builders that want to create something unique in the blockchain space. Something that is not possible on any other chain.
Partisia Blockchain is the worlds first blockchain that combines a generic programing language to enable a customizable secure multiparty computation (sMPC) solution into an interoperable and scalable blockchain.
Unlike other privacy blockchains that do zero knowledge proof, or only a specific MPC function, Partisia Blockchain’s research based sMPC allows for customizable solutions to fit your specific needs. With features that allow for solutions to be regulatory compliant (such as GDPR, HIPAA, etc), and fully auditable, Partisia Blockchain allows for the solution to solve problems in many use cases.
Our ecosystem is full of unique real world projects that are unique in the blockchain space. From solving for MEV attacks, tackling tender corruption in the public domain, to meeting CSRD compliancy, privatizing DAO voting to ensure integrity of the vote, our partners are not building yet another same type of application in other blockchains. And this is where we want you to come in to build something unique, something not seen in the industry.
Our grant guidelines are here, but mainly we are looking for teams that really want to create a unique solution that cannot be solved in other blockchains. We provide the infrastructure and the technology to bring these solutions to life. We are looking for teams that are really looking to stand out from other dApps, or solve for a problem that is currently not possible in other blockchains.
If you already have an existing app, you dont have to port your existing app over into our blockchain to take advantage of our MPC tchnology. You can use our MPC-as-a-Service model to request the computation as a service. Our interoperability model allows for other tokens (Eth, BNB, Polygon USDC, with more to come) to be spendable as gas on our chain, allowing flexibility to existing applications to take advantage of our technology as well.
What is your unique idea? What are some of the problems you have not been able to solve in the blockchain space? Do you want to create something unique to stand out from all the other similar dApps that do the same thing?
Lets build something different together!

At present, it requires a fair amount of technology knowledge to build and support a node in PBC. While many who do not have a technology background have been able to build and maintain nodes, it still creates a barrier that many individuals or organizations feel hesitant to cross. The other challenge is the current staking and job association process. Because the staked MPC tokens in a node are being used as collateral for all the types of jobs the node is running, unstaking and unassociating tokens that are being used can be a challenge.
This is why we are putting focus on implementing a simpler node setup and operations process. This will allow easier setup of nodes as well as easier associating and dissociating of your tokens.
These new features will be rolled out in phases, with the first one being automatic node registration. A simplified registration process will be rolled out where just the configs on your node will kickstart the KYC/KYB and the registration process.
Second phase of the project will be to simplify the association and dissociation of your staked tokens. It will all be a part of our “Staking 2.0” model, which will look to make it easier and less restrictive for both node operators and delegated stakers to manage their stakes.
Running a node will still require some level of technical skill. We hope by automating some of the process, it will make it less confusing and easier for the registration process.

As we continue to see development occurring on our blockchain, we are always on the lookout for feedback on how to improve our platform, either to make it easier for developers to develop on, or to add new functionalities to help improve the product offering by the teams developing on our chain.
In the last 6 months we’ve been listening to the developers and have been working on various new functionalities and features that should help improve the quality and functionality of the projects. Some of them came in the form of development tools which we reviewed last week.
In this article, we will review the new feature sets that are upcoming to help developers improve upon the existing features or add new functionalities.
Some of these features will also create new use cases for the MPC tokens
Improvements in the PBC as a Second Layer Functionality
One of our main value propositions is our cross-chain bridge (Hermes). This unique bridge and gas payment system allows other chains to be a usable asset in Partisia Blockchain. It is this bridge that allows other chains to call our MPC technology as a service and pay for it using their native coins. But at the moment the data that is transferred is through manual data attestation, and the transfer only occurs in one way (PBC -> EVM).
By implementing BYOC messages to be supportable, we will now implement a two way communication system. This allows for the smart contract writer to hook events that are happening in the EVM back to PBC. Through adding a MPC powered threshold key and tying our oracle servers to collateralize these data through MPC tokens, developers will now be able to create an automated bidirectional flow of data between the EVM and PBC. This opens up additional functionality, such as adding message information in NFTs and allowing them to be transferable cross chain, or sending and receiving of data during the actual bridging transfers.
Staking as an Insurance
Currently, once the funds inside a smart contract runs out, the contract gets deleted. We will be creating a new method to allow for SC owners to stake their MPC tokens as insurance to allow for these smart contracts to continue to live on even if the funds run out of the contract. This will allow for both a safety mechanism in the event funds do run out and also introduce another use for MPC tokens.
ZK Contract Lifetime Beyond 28 Days
Currently the data in a ZK contract lasts for 28 days. Going forward, we will introduce a way to allow for this data to be extendable to go past the 28 days through staking MPC tokens and re-funding the smart contract.
ZK Computation in Batches
This feature will allow for multiple ZK computations to be batchable so that you do not have to execute each and every computation one at a time.
Allow ZK Contracts to Control User Data
Currently the developers writing ZK smart contracts do not have flexible control of the Zero Knowledge data. Through this feature, we will allow for developers to have greater control of the type of data and the control of how the data will be used.
We hope that the above will both help improve the speed in which development can be done as well as allow for new features to be implementable by the developers.
As each of the items complete, we will make a separate announcement in our development channels.

Bitcoin is what started it all. The coin that began the blockchain industry and even over 14 years after its initial creation, and after so many new coins trying to improve upon the original, it still stands as the king of crypto currency. It is still the main form used as payment in the blockchain industry and others are either built as bringing functionality more than being a currency or is relegated as 2nd place at best.
As mentioned in our interoperability article, the current blockchain L1 ecosystem are basically in a zero sum game. Every chain is trying to be faster, cheaper, more secure and easier to build on. And each blockchain operates by using their own native coin for their transaction fees. And as DeFi came into the picture, DEX’s began looking for options to allow for swapping between chains that were not native to itself. Enter wrapped tokens.
Currently in the DeFi ecosystem, there is only one way to trade BTC. By creating a wrapped version of itself. Whether its wBTC, HBTC or renBTC, etc, it is basically all a similar form of custodying a BTC and minting an IOU type mirror token on the native network. When the smart contract holding the mirror coin is burned, then the locked, or custodied real bitcoin is released. One of the problem in this system is that you must give trust to the custodians. Not only does this go against the trustless-system ethos of public blockchains, if something happens to the custodians (hack, out of business, etc) then your wrapped tokens could be lost or become worthless.
While Partisia Blockchain can implement wrapped bitcoin as BYOC asset easily, this fundamental architecture of wrapped bitcoin tied to a custody goes against the principles of allowing native coins to be used as a form of transaction payment in the blockchain. As mentioned above, from price parity between real and wrapped BTC, to security issues raised by using a custodian (corruption or even worse, a hack in the custody system) there were too many compromises. And so we are taking the road less traveled and working toward finding a solution to allow for native bitcoin to be usable as an asset in the Partisia Blockchain.
This means we are creating a multi-phase program to build this road. The first phase will be a research phase. We’ve already begun this effort and hope to complete it in the next few months. Once the research is complete, we will know the effort needed and then will engage in an architecture and engineering sessions to plan out the work to accomplish this.
This has some major possible benefits. From allowing users to spend native BTC as gas transactions for applications built on the Partisia Blockchain, to creating a native token swap between BTC and another BYOC chain, or even helping to scale transactions in the bitcoin network, implementing native BTC directly in the Partisia Blockchain network will open up new possibilities in the blockchain industry as a whole.
Please be on the lookout for future news of the results of this research.

Currently our MPC protocol (called REAL) computes binary protocols, but we are going to add an arithmetic protocol in the not too distant future. The “binary” or “arithmetic” property of a protocol is not an indication of what is possible, but rather what is efficient.
Every MPC protocol operates on units of some type, and all applications using MPC are built using a very very small set of operations on this type. Some types are better at some applications than others, which motivates supporting protocols that operate on different unit types.
In binary REAL, the “unit type” is a bit; that is, a number that is either 0 or 1. The only operations we can perform on these bits are exclusive or and conjunction (or XOR and AND). All other protocols have to be built using one or more bits, and a combination of XOR and AND operations.
This naturally means that protocols that can be efficiently expressed as a combination of XOR and AND operations, would be efficient in binary REAL. Such operations include comparisons, any kind of bit manipulation, rotations, shifts, and so on.
On the other hand, operations that require a lot of XOR and AND operations, would be in-efficient. For example, additions, subtractions, multiplications and essentially any operation that is “arithmetic” in nature.
In Arithmetic REAL, on the other hand, the “unit type” is a number between 0 and n (for some n) — and the only operations we can perform are addition and multiplication.
Arithmetic REAL therefore performs very well in applications with a lot of arithmetic. That is, a lot of additions, subtractions, multiplications and so on. On the other hand, applications with a lot of non-arithmetic operations are expensive. For example, it is not very easy to compare two numbers, if all you’re allowed to do is add and multiply the two numbers being compared with each other.
Binary REAL, being binary (or boolean) in nature, performs well on applications that are, well, binary in nature. This includes applications such as
Arithmetic REAL, being arithmetic, performs well on arithmetic applications:
By enabling arithmetic computations in Partisia Blockchain, we aim to open up new solutions as well as allow for cheaper and easier implementation of existing ones. From health record analysis to private voting in a massive scale, we hope to achieve a much wider acceptance of MPC as a perfect solution to enabling computation while protecting individual users’ privacy.
Be on the lookout for this sometime in the 3rd or 4th quarter of 2023.

The technology stack has been built over the past two years with Weezi team, who now migrated full-time to SecondLane.
There are six essential features that are gradually being automated and released by the team. Each of these features represents the steps of a typical OTC deal.
Such features are bundled into three versions of the SecondLane platform, with SecondLane V1 up and running on EVM-compatible chains.
We are honored to be trusted by Partisia Blockchain to integrate the Partisia ecosystem’s main characteristics into our SecondLane V2 release.
The core element of SecondLane V2 is automated on-chain onboarding and verification of users and assets. This has to be done in (a) a compliant, and (b) privacy-preserving form; so that buyers and sellers are sure that their information is not known to the public.
Partisia Blockchain’s ZK MPC technology, coupled with the decentralized consensus of oracles, is the right mix of tools for our task.
The innovations set to be introduced by Partisia Blockchain is long awaited in the market, and we at SecondLane are excited to be among the first partners to integrate those into our product for our client base.

One of Partisia Blockchain’s core values is in collaboration. Our belief is that one of the main paths to advancing the further adoption of the blockchain industry is through working together. And this belief is built into our blockchain architecture.
As mentioned in our interoperability article, the current blockchain ecosystem is kind of like going to an amusement park. You can play in an ecosystem but only if you pay using their native token.
Partisia Blockchain’s payment mechanism broke away from this paradigm and designed a tokenomics that uses other chains tokens. We started off with Ethereum, then added Polygon USDC, and then integrated BNB into the chain. Now, we are bringing the ability to onboarding tokens to the community.
With the new Ethereum BYOC Framework, we are enabling the ability for any community developer to submit a proposal to onboard a ERC20 or a BEP20 token of their choice that is running on the respective chains into the Partisia Blockchain bridge. This brings the control of adding a token into the Partisia Blockchain to the public.
How it works:
By enabling this important roadmap item, we bring the control of onboarding any new Eth or BNB based asset into our unique bridge to not only be used as a swappable tokens, but allow it to be usable as gas for transacting in the Partisia Blockchain network. Whether you are a dApp that wants to add privacy services into your existing application, or create a unique DeFi solution on Partisia Blockchain that allows for swift easy swaps between assets while preventing front running and sandwich attacks through MPC, all of the value proposition that Partisia Blockchain offers is now available to any system running in the Etherium, Polygon or BNB chains.
Please look out for this feature being launched sometime in the 3rd/4th quarter.

Scalability has been something that architects have been grappling with for many years. In the technology space, being able to scale both vertically (adding capacity) and horizontally (adding instances) has been grappled with in all parts of the technology stack. Do you add more transistors in a CPU or add cores to work together? Do you add more space in a hard drive or add multiple hard drives to work together? Do you build a faster computer, or create a software architecture to use multiple computers in sync?
One thing is for certain however. Scaling vertically has limits. There is only so much CPU, memory, storage you can add to a single system before it runs out of capacity.
Blockchain space is no exception. As adoption grows, so must the ability for a blockchain to handle the additional transaction on chain as a result. And in the blockchain space, we call it TPS (transactions per second) This is a combination of two metrics;
Different blockchains use different architectures to try and achieve faster throughput. For finalization, there are things like probabilistic and deterministic finalization. To achieve a higher number of transactions, blockchains have turned to sharding, and added on different rollup technologies like ZK or optimistic roll ups.
To create the fastest blockchain, you have to first look at what can theoretically be achieved for the above two factors. For the finalization time, the fastest is instant. As soon as the block is created, you want it to be finalized as fast as possible. For the number of transactions in a block, you want to be able to put the number of transactions in a blockchain can handle to be as much as possible. The more transactions you can process at the same time, the faster your chain will be. And all of this needs to be done in a secure manner. So how does Partisia Blockchain handle these two challenges?
For finalization, PBC has implemented a unique consensus model that consists of three parts.
This unique finalization model allows for blocks to be created and finalized in real time with the only limit being the time it takes for the verification signatures to propagate throughout the network. (More info in PBC’s yellow paper section 3.1)
While the term “sharding” has been popularized by blockchain, its actually a term that was coined back in the 1990s, by an online video game company, of all places. During the initial popularization of MMORPG (massively multiplayer online role-playing games) the company building the game Ultima Online ran into a scalability problem. To solve the problem of scaling out huge worlds for hundreds of thousands of users to interact with, they came up with a database scaling architecture and coined it “Sharding” This sharding architecture caught on and is now actively being used by many different database products, including MySQL, Oracle DB and MSSQL.
Blockchain has borrowed the term but if you look at the general architecture of most blockchains, it does not conform to the general principles of what sharding really means. In blockchain sharding, while blocks may get created in parallel, it still gets appended to the end of a single chain.
Through “speed of light” finalization we tackled the issue of creating finalization instantly. For the transaction per block issue, we looked to architect the sharding model according to the definition of what sharding really is; True parallel processing of data.
Just like how it is in traditional databases, in Partisia Blockchain, each shard is an independent blockchain. And each shard ,or blockchain, is capable of independently creating, validating and confirming a block. This architecture goes back to the original definition of what a shard is and allows for true parallel processing of blocks. And in the event congestion is detected, the system automatically creates a new shard adding additional capacity dynamically. Through this dynamic scalability architecture, Partisia Blockchain can theoretically scale infinitely, only limited by the number of nodes in the blockchain.
By creating a programming language that allows for developers to use MPC in a generic way, Partisia Blockchain Foundation has made the creation of applications that can harness the power of MPC for different use cases a possibility. Partisia has been at the forefront of providing private MPC solutions since 2008. And by layering this technology on top of an interoperable and scalable blockchain, Partisia Blockchain is paving the way for anyone to create blockchain solutions that can balance privacy and transparency to build trust and ensure integrity.
