Guest blog from Anton Glotser, CEO of DelNorte
DelNorte is digitizing, tokenizing and monetizing bureaucratic processes. In governments and corporations bureaucracy is often time consuming, cumbersome and in the worst cases prone to corruption. Many governments and some corporations are still using the millenia-old method of pen and paper for bureaucratic processes. Our partnership with Partisia will help us modernize that process.
DelNorte solves the problem of security, transparency, frequency, efficiency, scalability, fidelity and friction. By converting physical documents to digital and storing them on the blockchain we solve about 95% of the problems associated with traditional paperwork. Not only does this greatly improve quality and security of the data, but our solution provides an unfathomable amount of ancillary benefits. Having guaranteed and secure real time data associated with physical assets, such as real estate deeds on the blockchain, makes the assets represented by these smart tokens significantly more valuable.
Working with Partisia Blockchain offers several notable benefits both for us and our clients. Partisia Blockchain utilizes cutting-edge cryptographic techniques like secure multiparty computation (MPC) to ensure that sensitive data remains confidential even while being processed on the blockchain. It addresses scalability challenges by enabling efficient computation and data processing. As we occasionally get requests for a variety of blockchains, Partisia accommodates us with their interoperability across blockchains and systems. Also dealing with governments security is a top priority for us. Partisia utilizes advanced cryptographic techniques to protect data and transactions. The last important point is our ability with Partisia to mold a variety of regulations and customization to specific use cases and business requirements.
We have contracts for pilot projects in El Salvador, Mexico and Honduras. Our most advanced and tested project is in El Salvador. There we have live transactions and are now expanding to other services like digital signatures stored on chain, and a national expansion for tokenized deeds and titles.
We also have a product called Kasas.io, it is a real estate search engine and marketplace that allows anyone to buy, sell, rent or invest in whole property or fractions of real estate remotely and completely legally in all of Latin America. In the places where we have a direct link to the government we can even perform 100% digital remote real estate transactions for purchase or sale, with digital NFT deeds and titles issued virtually on chain and recognized by the government as official. You can hop on a plane and buy a house mid-flight, and by the time you land in that country (El Salvador at the moment), you will already own the house.
DelNorte stock is registered and we are currently raising US$2 million for 20% of the company to fuel our national and international growth. We are in the process of expanding to about a dozen countries in Latin America but also into parts of the USA. We are expanding our tech stack and our private sector operations for automated real estate transactions.

Trust, the cornerstone of any relationship, holds profound significance in our interconnected world. Whether it be interpersonal, inter-corporate, or even between governments, trust is the linchpin upon which successful relationships are built. Partisia Blockchain, in its essence, is a catalyst for redefining trust in the digital realm.
“The art of enabling trust within an inherently untrusting environment.”
But how does Partisia Blockchain achieve this monumental feat?
The importance of trust is a concept we can all readily grasp. Yet, the question arises – what facilitates trust among entities? A critical factor in this equation is privacy. Trust cannot manifest in a realm of complete anonymity. However, it also cannot thrive in a domain of absolute transparency. The sweet spot lies in a harmonious blend of both, where transparency and privacy coexist to cultivate trust.
Consider a simple scenario: applying for a credit card. A bank, to grant you this privilege, requires crucial information about you – your identity, income, contact details, and credit history. These details are essential for the bank to extend its trust in you. However, if you knew that these details would be made public, including your transaction history, your willingness to apply for that credit card would understandably wane.
Upon closer examination, it becomes clear that privacy is the very bedrock upon which trust is constructed.
In our credit card example, you enter a trusted environment where you bestow your trust upon the credit card company to safeguard your personal data. The company is, of course, bound by its business model to keep the sanctity of this trust. However, there is an underlying vulnerability here – data breaches, unauthorized sales, or inadvertent data exposure. These are potential avenues through which your trust can be shattered. In such cases, you are placing trust in the environment.
On the other hand, a trustless environment requires no implicit trust in any single entity but still manages to perform necessary functions seamlessly. Enter the decentralized blockchain, a prime example of an environment where trust in an entity is unnecessary. Here, blocks are formed, and information is inscribed on the ledger without a single entity having dominion over the system. The laws of physics exemplify another trustless environment – they exist without needing trust because the system is transparent, having been measured and documented, and accessible to all for independent confirmation.
Partisia Blockchain ingeniously fuses these concepts to tackle the trust predicament. It enables two entities to work together within a trusted framework, devoid of any single entity’s control. The synergy of multiparty computation (MPC) and blockchain technology underpins this innovation.
MPC, a revolutionary technology, permits the computation of confidential data. It functions as an encryption technology, allowing input values to remain hidden while still computing answers. It empowers us to calculate the sum of 2 and 3 without revealing the original values. Envisaged in the late 1970s and officially introduced in 1988, MPC boasts an illustrious history, with over a thousand research papers and 15 years of practical implementation.
In parallel, blockchain, the other keystone of Partisia Blockchain, has been redefined to its very core. Through our distinctive BYOC tokenomics principles and an infinitely scalable architecture, we make trust in a trustless environment a reality for all – not just for those building on our platform.
By converging these two technologies, Partisia Blockchain democratizes trust within a trustless domain. This manifests as a wealth of opportunities: companies collaborating without exposing their confidential data, creating equitable, private, and accurate voting systems, returning control of data to users, and enabling monetization of data. In the heart of Partisia Blockchain’s mission lies the potential to revolutionize business models and unveil novel value propositions.
At Partisia Blockchain, our journey is guided by over 35 years of relentless dedication to encryption technology. Our Chief Cryptographer, Ivan Damgård, the mastermind behind the Merkle–Damgård Construct, which underpins renowned hash algorithms like MD5, SHA-1, and SHA-2. His groundbreaking work in the 1980s laid the foundation for secure multiparty computation (sMPC), and today, this profound expertise empowers us to champion the most advanced sMPC protocol globally.
Our mission is to redefine the very essence of trust, forging a fresh perspective on how data is employed. To bring this vision to life, we had to excel not only in sMPC but also reimagine the architecture of public blockchains.
Secure multiparty computation is an encryption marvel that permits data computation without revealing the underlying data itself. Imagine a sophisticated dance of algorithms that enables outcomes like auctions, data analysis, voting, surveys, and random number generation without divulging the precious data within.
The blockchain ecosystem grapples with two pressing challenges: interoperability and scalability. From an interoperability standpoint, every blockchain acts as a unique asset class, fueling a competitive zero-sum game mentality. Each Layer 1 blockchain claims supremacy, leading to a winner-takes-all narrative. Furthermore, users are bound to a specific blockchain, having to acquire and use that particular token as an entry ticket, reminiscent of an amusement park experience.
On the scalability front, the single-database nature of blockchains poses hurdles related to both scalability and transaction speed. Overloaded blockchains often suffer from delayed transaction confirmations and a lack of real-time efficiency.
To fulfill our visionary goals, we realized the need for a groundbreaking re-architecture of blockchain technology.
In an environment where blockchain networks resemble amusement parks, we introduce a paradigm shift. Rather than being confined to one park’s rides, our mission is to let anyone access our innovations, irrespective of their token holdings. We have engineered a system that embraces tokens with liquidity, allowing them to serve as transaction payments within our ecosystem. Our BYOC tokenomics foster a vibrant ecosystem where different token types can facilitate transactions, ensuring all users can harness our sMPC technology. Our native MPC token, in turn, bolsters our blockchain’s security, as node operators stake their tokens as collateral, safeguarding our network.
Traditional blockchains grapple with scalability issues, impeding real-time finalization and usability during high traffic. Partisia Blockchain confronts this challenge head-on by adopting a revolutionary approach. We have re-engineered the traditional method, enabling horizontal scaling and boasting a rapid .3-second finalization time in normal conditions. Our network comprises multiple blockchains, each autonomously producing blocks, creating an unparalleled scalability model. Moreover, our unique BFT consensus mechanism ensures “speed of light” finalization. For in-depth insights into this architecture, refer to our yellow paper.
These distinctive attributes empower you to craft pioneering solutions that revolve around trust. We extend an invitation to all those seeking to enhance trust and privacy within their applications. Reach out to us, and let’s explore unique solutions to your challenges. Together, we can reshape the digital landscape and usher in a new era of trust.
In the ever-evolving landscape of regulations, a multitude of rules and safeguards has emerged, from antitrust laws to data protection rights, designed to uphold ethical standards and protect individuals from exploitation in a rapidly changing world. However, the blockchain industry, despite its transformative potential, faces a notable gap in regulatory compliance and ethical conduct, owing to its inherent transparency and anonymity.
Partisia Blockchain emerges as the vanguard of change, offering innovative solutions that bridge this gap and establish a new paradigm of integrity in business.
Illustrating GDPR compliance
One of the most prominent and far-reaching regulations in the realm of data privacy is the European Union’s General Data Protection Regulation (GDPR). GDPR, along with similar laws worldwide, dictates the governance of personal and sensitive data, with a key requirement that such data remains within a specific geographical region. This presents a formidable challenge for traditional blockchains, given their inherent transparency and the global distribution of nodes.
Partisia Blockchain, however, is uniquely attuned to regulatory requirements. We have introduced a pioneering feature known as “jurisdiction management” into our system. This remarkable capability empowers users to designate data that must remain within nodes situated in a specific jurisdiction. By leveraging secure multiparty computation (MPC), developers can selectively privatize data, ensuring compliance with stringent data privacy laws while preserving the integrity of the blockchain.
In the realm of corporate governance and shareholder meetings, stringent rules exist to ensure the fairness and impartiality of votes. Maintaining the confidentiality of individual votes is paramount. However, traditional blockchain voting mechanisms, as seen in decentralized autonomous organizations (DAOs), suffer from complete transparency, making it challenging to protect voter privacy. Existing techniques to privatize votes often stumble due to scalability constraints or the inadvertent revelation of votes after the tally.
Partisia Blockchain introduces a game-changing solution through secure MPC, allowing computation of vote results without disclosing the specifics of individual votes on the blockchain. This innovative approach guarantees an immutable voting record, upholding the highest securities standards while preserving voter anonymity. It is a trustless system that harmonizes blockchain technology with compliance, setting new standards for ethical conduct.
Partisia Blockchain stands as the vanguard of a revolution in the blockchain industry, where privacy and compliance are not just buzzwords, but integral components of the ecosystem. Our solutions transcend the limitations of transparency and anonymity, offering a bridge to ethical and regulatory compliance.
In this rapidly evolving business landscape, where rules and regulations shape the playing field, trust in blockchain technology is not just a vision; it is a reality. Embrace Partisia Blockchain, and unlock the future of ethical, compliant, and privacy-respecting business practices. It is time to redefine the rules and raise the standard of ethical conduct in your organization.

To make it more accessible and engaging, we have moved all Hivemind Huddles to Parti.com. On 22 September 2023, we hosted our first one on the platform. We delved into the world of MetaMask Snaps and their significance. Bruce Ahn, our Head of Developer Relations, shared his experiences and insights from Korea Blockchain Week, Token 2049, and more.
During our week of events at Korea Blockchain Week, we immersed ourselves in various activities, attending multiple side events, engaging in speaking opportunities (thanks to H.E.R. DAO), and collaborating with our Korean Ambassadors. Together, we championed the cause of privacy-driven innovation using Partisia Blockchain. Notably, we observed the absence of Layer 1 (L1) blockchains, indicative of the current market. On the bright side, there was a sizable increase in zero knowledge events, signaling a shift in the industry. These developments highlighted the growing recognition of interoperability in the blockchain space. The event also resulted in promising leads and partnership opportunities, especially in areas such as DID/SSI solutions, gaming, and ZKP technology.
Our Token2049 visit offered an exciting glimpse into a city state known for its unique mix of cultures. The event-packed week showcased Singapore’s vibrant blockchain landscape with daily highlights. At Eth Singapore, we explored potential collaborations with various projects and discussed future prospects. Decompute, a dedicated MPC conference, demonstrated the growing emphasis on privacy solutions in blockchain, with mentions of Partisia Blockchain’s preprocessing method. We were proud sponsors of IoTex’s side event, where our Co-Founder Brian Gallagher delivered a compelling speech, presenting our interoperability model. We also took the opportunity to tease our future announcements. Token2049’s bustling main conference floor revealed a thriving blockchain space, with themes centered on ZKP, interoperability, NFTs, and service providers. This event generated a wealth of promising leads that we are eager to follow up on in the coming months.
We have continued to see a large number of leads come in for the month of September, largely due to our participation in KBW and Token2049. While the lead numbers will fluctuate month by month, we feel this will continue with our additional participation in going to conferences in the future.
In total, 1,690,626.9629 MPC tokens will be paid out in rewards, almost 500,000 MPC more than the previous quarter. This is our largest quarterly distribution to date.
We are thrilled to announce our participation and sponsorship in this year’s CV Summit, taking place in the picturesque Swiss town of Zug on 3–4 October 2023. This event is a premier gathering for blockchain and crypto enthusiasts, and we wouldn’t want you to miss out on the action!

In all blockchains, node operators are running their nodes to operate and secure the network. And the compensation model of the blockchain allows node operators to get compensated for maintaining/operating the protocol. On Partisia Blockchain the compensation is a mix of BYOC fees and rewards in MPC tokens. Rewards come from the ecosystem pool used to bootstrap the operation of the network.
Currently the distribution of rewards is the same for staking directly by a node operator account as for any other account that delegates staking to a node operator. On the other hand, node operators receive all BYOC fees. However, at this early stage of the network the main compensation as node operator is the rewards. Hence, to make the total compensation more fair to the node operators operating the network the following adjustment will be put up for voting among node operators: 2% of the rewards gained by delegated staking to be distributed to the node operators that they are staking to. This will allow a fairer staking rewards system where the node operators running the system will be compensated by the community stakers for providing the computing power to stake their tokens to and receive rewards.
A simple example for a community staker would be if the reward for your current period was 100 MPC tokens, during the rewards computation, 2 MPC tokens will be sent to the node you are staking to, and you will receive 98 MPC tokens. This will fairly compensate the node operator for operating the blockchain you are staking to receive your reward.
If you are a node operator, you will receive 2% of all the staking reward your node account generated for all the community stakers you are supporting.
As this is a governance matter for the chain, the proposal will be put to a vote for the block producing node operators to decide on. We suggest for those who are staking, that you reach out to your respective node operators and voice your thoughts with them directly. If passed, this will be implemented as a part of the Q6 reward cycle and subsequent cycles going forward.
We hope this will help create a more fair rewards distribution as well as promote node operators to continue to promote their nodes to the community to stake to.
Thank you for your continued support!
ZUG, 18 SEPTEMBER 2023. Partisia Blockchain is proud to announce the launch of a pioneering integration with MetaMask, the leading self-custody Web3 platform developed by Consensys, opening untapped opportunities for more than 100 million users. With the introduction of MetaMask Snaps, a transformative enhancement for users, we are poised to revolutionize the world of decentralized applications.
Snaps opens a new realm of possibilities for Partisia Blockchain users by leveraging MetaMask’s trusted functionality. The initial Snap integration brings MetaMask signing to Partisia Blockchain users, and opens up an array of innovative programmable features and functionalities within their wallets. After a meticulous selection process, Partisia Blockchain was selected by MetaMask based on the Snaps integration work done by our developer team. The Snaps is set to elevate the user experience, focusing on transaction insights, interoperability with non-EVM blockchains, and notifications, offering users unprecedented control and customization.
In 2022, MetaMask surpassed 100 million users. The launch of Partisia Blockchain Snaps marks a significant milestone as millions of MetaMask users can tap onto our innovation. Each Snap selected by Consensys has undergone rigorous security audits and has been thoughtfully integrated into MetaMask’s allowlist, ensuring a secure and seamless experience for users.
Kurt Nielsen, President of the Partisia Blockchain Foundation, says: “The major driver behind the Partisia Blockchain project is the disruption of data as we know it. With the MPC-as-a-Service built directly into the Partisia Blockchain, any service on the internet can build the next generation of privacy-preserving advertisement, searching or matching services without touching the users’ data. This is a tremendous opportunity, and a large part of the motivation for building the Partisia Blockchain in the first place. While the Partisia Blockchain network is ready, we need to bring in the users of the internet and activate the users’ private data. This is the next major step and why the integration with MetaMask is a major step forward.”
The benefit of the first Snaps iteration is the ease of using MetaMask for transaction signing. It will enable users, which also use other blockchains, to employ a single trusted wallet across chains and remove friction. The ease of cross-blockchain solutions — such as bring your own coin (BYOC) and MPC-as-a-service — will be significantly more user-friendly. In the future, the Partisia Blockchain MetaMask Snap will offer more features helping users secure their confidential personal data by employing MPC technology.
The Partisia MetaMask Snaps will enable developers building on Partisia Blockchain to integrate MetaMask as the signing solution into their own dApps and establish a direct connection with their users. In the long run, users will reap the benefits of the convenience and versatility offered by Partisia Blockchain Snaps, tailored to various use cases and compatible with multiple protocols.
Kurt Nielsen continues: “The Snaps that come with MetaMask allow us to build security solutions that safely and privately bring the more than 100 million users’ data into Partisia Blockchain and the next iteration of the internet — an evolution where technology returns control and privacy to the users of the internet.”
Christian Montoya, Product Lead for MetaMask Snaps, emphasizes the importance of permissionless innovation within a decentralized system: “We believe that permissionless innovation is a cornerstone of a decentralized system — no gatekeepers. Innovation thrives at the pace of the network, not just within an individual development team at Consensys.”

During the month of September 2023, I will be traveling to a few conferences, and doing a few speaking engagements. As a part of the conference going, I will be providing a few thoughts on what I have seen, people and projects I have met and the changes and trends emerging in the last year or so in the industry.
My first time in Singapore! The second week of my event experience was at Token2049 in Singapore where I got my first taste of a city I heard so much about but never experienced. I expected it to be a very high end place with expensive cars and high rises. To my surprise it was more like a mix between Hong Kong and Miami. A very laid back Hong Kong maybe? Either way it is an amazing place and I am wishing I could stay a bit longer
The week was far more busy than Korea Blockchain Week (KBW) where there was a significant event every day.
Monday: Eth Singapore — The event was co-hosted by AngelHack who is a good friend of ours. Ryan, the CEO, helped us feel at home and we discussed our potential future collaboration. It was once again devoid of L1 but I did see quite a number of cloud computing providers selling their services. From Google to Huawei, more and more cloud service providers were looking to help build nodes on blockchains.
Tuesday: Decompute (MPC conference) — On Tuesday, I visited a specifically MPC based conference called Decompute. Yes, an actual MPC dedicated conference in a blockchain week. It was amazing to see a ton of MPC focused blockchains coming up and to me it showed the continued emergence of privacy solutions in blockchains. From Nillion to Aptos to other various smaller names, a lot of folks were working on MPC solutions. In fact, during the Q&A session with Aptos, someone raised a question asking “how does this compare to Partisia Blockchain’s preprocessing method?” 0_o Wow, someone who actually has heard of us! I made sure I got his contact and will be following up with him in the future.
Wednesday: IoTex side event (where we were one of the sponsors) —Wednesday was the big event for us where we had Brian Gallagher, one of our Co-Founders, speak in a large side event held by IoTex (one of our future integration partners) and we presented our interoperability model. We also showcased our new banners which we think are much cleaner than our old ones. While I grayed out the new logo here on these pictures, we will be revealing this soon. With Vinny Leow and Markus Spillmann with us, we made sure our presence was felt!
Thursday: Token2049 —Thursday was the visit to the main conference. And there was a huge difference between KBW and Token2049. It was two full floors filled with booths to the brim. There was absolutely no way you could visit them all and all I got was just a very small sample of the different projects that were on display there. It certainly did not feel like a bear market at all.
With that said, like in KBW, the main theme was in ZKP, interoperability, NFT and a lot of service providers.
I met up with a ton of potential leads, which we will combine with the KBW and beginning next week, we will begin following up on them.
My next stop will be in Zug to attend the CV Summit with a larger Partisia Blockchain team in early October and then off to Milan for a speaking engagement at EthMilan. If you are around the area, please let me know.

During the month of September and early October 2023, I will be traveling to a few conferences, and doing a few speaking engagements. As a part of the travel, I wanted to provide a few thoughts on what I have seen, people and projects I have met and the changes and trends emerging in the last year or so in the industry.
Even just a year ago, zero knowledge proof was barely a topic of conversation. Now, almost everyone had some level of understanding of what MPC was.
My first week of events was in South Korea, my birthplace, and I spent the week going to multiple side events, did a quick speaking engagement (thank you H.E.R. DAO for the opportunity) and met with a variety of builders, projects and community builders.
I also got a chance to meet with two of our Korean Ambassadors, which was an amazing opportunity. We teamed up for three days going around different side events promoting building for privacy using Partisia Blockchain.
My first thought was with the amount of missing L1 blockchains in the industry that was present. It clearly still is a bear market and as a result, L1’s were visibility absent. One person I spoke with, when I mentioned I was from an L1, said “oh no, not another L1!” And I think that reaction makes sense. As mentioned on our interoperability article, L1s are all playing a zero sum game. Everyone is in competition with each other and the industry is trying to mature into more of an interoperable environment. To me it was a good sign not only for the blockchain industry but also for Partisia Blockchain, as people were beginning to understand the importance of interoperability in any industry.
My second thought was the amount of zero knowledge events that were out there. One out of every two to three events was either focused on ZK or had zero knowledge as a topic. Even just a year ago, zero knowledge proof was barely a topic of conversation. Now, almost everyone had some level of understanding of what MPC was. This was an amazing shift in the industry and I will keep you all updated to see if this trend continues.
Just on a side note, even the ZKP experts were conceding that ZKP has limitations in scaling and long computation times. My thought is that as the industry continues to mature, many people will begin to turn to MPC as a potential solution unless ZKP scaling issues can be resolved.
Overall, I met up with quite a number of potential leads and partnership opportunities. Quite a lot of leads to follow up, interesting use cases to delve deeper into and more opportunities to come from what I thought was a very successful event. A lot of the builders were focused on DID/SSI solutions, as well as gaming and ZKP technology.
More to come next week on our presence in Token 2049 where we will have a booth and a speaking engagement at the R3al World @ Token2049: Interoperability, Web3’s Disruption Point conference. If you are in the area, come say hello!

Nodes are the computers in the blockchain network. They perform services for the users of the blockchain, first and foremost they facilitate the transactions that happens on the blockchain. From the transaction costs paid by users, the node operator can make revenue. PBC has four types of nodes:
If you want to be a node operator you are required to have a stake in the network. A stake is basically a deposit strengthening the security and user confidence of the network. The stake means that the node operator has something to lose should they try to cheat or damage the network. Staking requires that the node operator buys the required stake of MPC tokens. Services have a hierarchy of cost and security as well as payment. Therefore, higher paid services require a higher stake. To acquire MPC tokens go through this contact page.
The current stake requirements are:
The machine
In addition to the stake you need a computer to run the node. Most node operators rent a server, but some keep the machine running the node in their own home. Machine requirements are detailed in the Recommended hardware and software section.
The keys
When a block of transactions is validated, the node signs off on it with a unique digital signature. The signature is created with the node owner’s private key. The signature is verifiable from the public version of the signing key. The different keys play different roles. One keypair references your account with the stake, another refers to your identity on the network and in the PBC internal register. A full description of the keys you will need can be found in this section.
The skills
Setting up the node requires some technical skills. You need to be able to configure and run your node, or alternatively pay someone you trust to help you with the setup and upkeep of the node.
Onboarding
If you want to run a node, please join our community. We would like to offer you the best possible support and be able to notify you in case we or community members register a problem with your node. We also send you news of relevant updates for example when node operators can support deposit or withdrawal of a new coin on the chain (oracle service). Node operators will also be alerted to upcoming votes on vital updates.
The following guide has 10 parts. If you do the steps of the guide in order, you should know how to set up your node correctly, before you commit your stake. In other words, you can find out if you have the skills and patience for running a block producing node, before you tie your stake to the performance of the node.
As explained in our BYOC documentation, Partisia Blockchain (PBC) has a multi-chain solution where gas for transaction in PBC is paid using external coins. To help developers add additional tokens into the chain, we have a framework that allows anyone who meets the requirements to add other tokens as a bridgeable asset and include them into the payment system. This document’s aim is to provide instructions on how you can add other tokens into the Partisia Blockchain ecosystem.
Currently the framework supports any tokens that run under Ethereum, Polygon or BNB chain. As other L1 chains get added, other tokens will become available under the BYOC Framework.
In the coming weeks we will provide additional guides and videos to walk you through the process, for both the node operators and the proposer. We hope this article will help you begin to consider what tokens you would like to onboard as payment.
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:
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.
August has been a busy month of success! Let’s dive into this month’s Partisia Blockchain update, exploring various industries to showcase the flexibility and transformative potential of blockchain and multiparty computation (MPC). From revolutionizing government processes with transparency and security to redefining data-sharing in marketing and advertising, while prioritizing privacy, our solutions continue to drive innovation.
The healthcare sector witnesses privacy-preserved collaboration and supply chain efficiency, while logistics embraces streamlined supply chain management through blockchain and MPC integration. In the community sphere, we have explored Self-Sovereign Identity’s (SSI) elevated privacy with MPC and tackled GDPR compliance through anonymization. The spotlight on Privacy Enhancing Technologies (PETs) broadened our understanding of blockchain possibilities. We hosted an insightful MPC Advantages Q&A session, and our dynamic community engaged in a Web3 marketing discussion — Hivemind Huddles.
Technical advancements include operational smart contracts for DID and verifiable credentials, BYOC framework deployment, and browser updates. As we power ahead, we eagerly anticipate unveiling the BYOC framework in more detail and introducing even more streamlined management features. Stay updated with another month of innovation and progress!
In this month’s recap, we have explored our Industry Spotlight and how Partisia Blockchain’s solutions benefit diverse sectors, including Government, Marketing and Advertising, Healthcare and Logistics. Our journey through these industries showcases the versatile applications of blockchain and Multiparty Computation (MPC), each tailored to address specific challenges while upholding privacy, security and efficiency.
Within the domain of government, Partisia Blockchain envisions transformative solutions that embrace the principles of transparency, security and efficiency. By harnessing the power of blockchain and multiparty computation (MPC), bureaucratic processes can be streamlined while maintaining the confidentiality of sensitive information. Initiatives, such as DelNorte and E-Trusty, exemplify how blockchain can enhance trust in public institutions, create transparency in public tenders, and uphold privacy in CBDCs and blockchain-based voting systems.
In the dynamic landscape of marketing and advertising, Partisia Blockchain revolutionizes data-sharing models. With our privacy-first approach and secure MPC technology, users gain ownership and control over their data. The combination of blockchain and MPC empowers data analytics companies to compute on encrypted data without compromising its privacy, rewarding users for data contribution, ensuring real-time data access, and maintaining transparency. Partisia Blockchain bridges the gap between consumer privacy concerns and data-driven marketing strategies.
In the domain of healthcare, Partisia Blockchain leads the charge in preserving privacy while fostering collaboration and innovation. Our MPC technology introduces secure data analysis without exposing raw information. In the realm of DNA sequencing, Partisia Blockchain ensures the security of genetic data. In clinical research, MPC empowers cross-institutional studies while safeguarding patient privacy. Supply chain management witnesses a transformation, enabling stakeholders to manage complex supply networks without revealing proprietary information. In clinical trial recruitment, MPC facilitates efficient participant matching while upholding data security and privacy. Partisia Blockchain redefines healthcare through the lens of privacy, security, and collaboration.
Lastly, we explored the impact of our solution on the logistics industry, envisioning a streamlined future where blockchain and multiparty computation (MPC) converge to enhance supply chain management. By integrating QR codes with tokenized product representations, we facilitated instant information access and reduced confusion. Blockchain’s transparent touchpoints improved logistics and supply chain transparency, while smart contracts automated processes and adapted to evolving documentation requirements. In the realm of quality assurance, we harnessed MPC and blockchain to digitize supply chains, ensuring privacy preservation and selective data access. Our solutions streamline documentation, upheld compliance with GxP regulations, and heighten efficiency throughout the supply chain, ultimately paving the way for a resilient and transparent industry transformation.
In this month’s community update, we highlighted the transformative impact of Self-Sovereign Identity (SSI) and Digital ID solutions within today’s dynamic data landscape. Partisia Blockchain’s MPC technology introduces an innovative dimension to SSI, elevating privacy levels and unveiling novel business models. Crucial to the foundation of digital identity, Decentralized Identifiers (DIDs) and verifiable credentials empowered users with data control capabilities. Expanding the horizons of SSI, multiparty computation (MPC) enabled confidential data analytics and versatile multi-functional applications.
Additionally, Partisia Blockchain discovered its vital role in facilitating GDPR compliance through the strategic application of multiparty computation (MPC) technology. The utilization of MPC ensured the anonymization of personal data, allowing for uninterrupted data collection while maintaining privacy. This decentralized MPC approach elevates data security and control, in alignment with the access and erasure rights mandated by GDPR. Additionally, our groundbreaking jurisdiction management v1.0 provides an innovative solution for geographically aligned data processing, effectively safeguarding data rights and privacy. 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.
On 10 August 2023, our vibrant community came together once again for an engaging Hivemind Huddle. This interactive session delved into the realm of Web3 marketing, exploring both the broader landscape and Partisia Blockchain’s unique strategies. Our conversation spanned across past successes like PR efforts, conferences, and media coverage, while also delving into intriguing future prospects (without divulging specifics). It was a great conversation where the community contributed with great ideas, some of which will be directly implemented through the Ambassador Program.

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.
