Blockchain technology is widely heralded as a transformative force for enterprise – from streamlining supply chains and enhancing financial processes to securing digital identities. It promises to radically improve how organizations manage data, trust, and transactions. Yet, many enterprises remain cautious about fully embracing public blockchain solutions because of concerns around security, scalability, privacy, control and regulatory compliance.
A compelling answer lies in a hybrid blockchain model – one that combines the best aspects of private (permissioned) and public (permissionless) networks. By integrating the control and confidentiality of private systems with the transparency and decentralization of public chains, enterprises can safeguard sensitive information while benefiting from global trust and interoperability.
Coupled with advanced solutions like the GODS Network, this approach not only addresses critical enterprise challenges but also drives broader public chain adoption.
It is important for us to outline what private and public blockchains are. This sets the groundwork for understanding why a hybrid model is best suited to catalyse enterprise adoption for the public blockchain network.

Examples in practice:
Think of a traditional bank. You access your account via a public app over a public network, but behind the scenes, the bank’s internal systems are protected by a secure intranet. Sensitive data like HR records or proprietary processes remain hidden, while only essential transaction data (like your account balance) is visible externally.
In web3, a private blockchain functions as this intranet, allowing sensitive computations to be kept confidential. Meanwhile, key outcomes—such as transaction confirmations—can be recorded on a public chain, ensuring transparency and immutability.
Large organizations often balk at placing any data on a fully public ledger—even if encrypted—due to regulatory constraints, internal policies, control, and privacy concerns. By offering a private network that seamlessly interfaces with a public chain, enterprises can:
It might seem counterintuitive, but as enterprises deploy private blockchains to manage sensitive data, they naturally generate key events—such as transaction finalizations—that can be recorded on public chains for greater transparency.
These on-chain records not only verify the private process but also bring real-world validation and transaction volume to the public ecosystem. Over time, this interplay boosts the credibility and adoption of public blockchains while enterprises get comfortable on the private side.
Multi-Party Computation (MPC) is a critical technology that enhances security by allowing multiple parties to compute functions over their data without revealing the inputs. In a hybrid model:
Decentralized MPC:
Centralized MPC:
Hybrid MPC Approaches:
GODS Network further the migration from enterprise blockchains to any public blockchain by not locking migration to a single public blockchain. It’s designed as a cross-chain data subscription layer that seamlessly connects disparate blockchains—whether private or public—through a simple, API-like interface. Here’s what makes GODS Network unique:
A hybrid blockchain model is the most practical solution for onboarding web2 enterprises into the web3 world. By keeping sensitive data and internal processes on a private network while using public chains for key transactions, enterprises can:
As enterprises increasingly migrate to hybrid frameworks, they generate a wealth of validated public transactions that enhance the overall credibility and interoperability of blockchain networks. Platforms like GODS Network embody this vision by offering a secure, scalable, and developer-friendly bridge that not only protects sensitive data but also catalyzes broader public chain adoption.
The journey toward enterprise blockchain adoption has been deliberate and measured, with enterprises seeking solutions that balance privacy, control, and regulatory compliance against transparency and decentralization. Hybrid blockchain models effectively bridge this gap by combining the best elements of private and public blockchains, delivering secure, scalable solutions that enterprises can comfortably adopt.
The banking analogy illustrates how internal systems (the “intranet”) can coexist with public interfaces, enabling both confidentiality and auditability. GODS Network enhances this hybrid approach by seamlessly connecting private and public infrastructures, streamlining cross-chain interactions and simplifying overall user experience. It is an essential tool for facilitating smooth integration and interaction.
As enterprises build confidence in this hybrid model, they will drive increased public chain activity, ultimately creating a robust, interconnected web3 ecosystem.

AI and blockchain – two of the most transformative technologies of our time – are converging to reshape how we interact with digital systems. At the forefront of this are AI agents: autonomous entities capable of performing actions in both Web2 and Web3 ecosystems without human intervention. Together, they can rewrite the rules of what’s possible.
Imagine this: An AI agent autonomously moderating content on decentralized social platforms, or collaborating with researchers globally, securely training on anonymized medical data to uncover patterns and suggest treatments for rare diseases – all while keeping patient privacy intact. Or an agent in DeFi, working tirelessly to rebalance portfolios and optimize liquidity based on real-time market trends. These are some of the realities that AI agents are beginning to make possible.
But these breakthroughs don’t come without challenges. Privacy concerns, computational limitations, and trust issues loom large before greater adoption of AI agents. Partisia Blockchain is tackling these obstacles head-on, using its cutting-edge Secure Multi-Party Computation (MPC) technology to pave the way for secure, scalable, and private AI agents.
AI agents are uniquely suited to Web3, where they can act autonomously within decentralized, trustless ecosystems to deliver transformative benefits. Here are some of them:
AI agents can securely train on encrypted datasets without revealing sensitive information. This capability supports applications like:
AI agents can monitor market trends, execute trades, and manage liquidity pools—operating 24/7 to maximize efficiency without human oversight.
AI agents autonomously moderate content and curate user experiences in decentralized communities. For example, an AI agent identifies and flags harmful content for community review, ensuring fair moderation without centralized oversight.
AI agents autonomously moderate content and curate user experiences on decentralized social platforms. For example, an AI agent identifies and flags harmful content for community review, ensuring fair moderation without centralized oversight.
DAO participation is often a challenge as significant amounts of users fail to participate in the governance of projects. AI agents can act as intelligent advisors or representatives in DAOs, simplifying governance. For example, an agent summarizes DAO proposals and recommends votes based on a member’s goals and historical decisions.
In Web3 gaming, AI agents enhance user experiences by acting as intelligent NPCs or personalized assistants, tailoring gameplay to individual preferences.
These opportunities highlight the transformative potential of AI agents. But their success depends on solving critical challenges:
To function effectively, AI agents require access to large datasets, which raises privacy concerns around sensitive information like financial records or medical histories. Robust privacy-enhancing technologies are essential.
Many current AI systems rely on centralized infrastructures, introducing single points of failure and security vulnerabilities.
AI computations are resource-intensive, and traditional blockchain networks often struggle to handle these workloads efficiently, resulting in high costs and congestion.
Users need confidence that AI agents are operating fairly and securely. Transparency is key, but it must coexist with strong privacy protections.
Partisia Blockchain is pioneering solutions that address these challenges, leveraging its privacy-first infrastructure and cutting-edge MPC technology to enable AI agents to thrive in Web3 ecosystems:
Partisia’s MPC technology allows AI agents to train on encrypted datasets without ever exposing sensitive data.

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.
For DeFi teams considering to build the next generation of scalable DeFi solutions on Partisia Blockchain, please find links to the scientific work, description, and template smart contracts below:
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.
