Web3’s potential goes far beyond digital currencies and non-fungible tokens. Real World Assets (RWA) are making their presence known, bridging the gap between the physical and digital worlds. Several projects showcased at the convention are pioneering solutions that enable the representation and transfer of real-world assets on blockchain networks. This innovation is set to revolutionize industries such as real estate, finance, and supply chain management by tokenizing assets and unlocking new opportunities for global trade and investment.

Digital identity reinvented

Digital identity is at the core of Web3’s promise to empower individuals in the digital space. Convention attendees learned how blockchain technology is redefining digital identity, putting users in control of their personal information. Projects focused on self-sovereign identity and decentralized identity management solutions are emerging as key players in the Web3 ecosystem. The discussions at the event explored the importance of identity ownership, the elimination of central authorities, and the protection of user data. Several identity projects showed great interest in the prospect of Partisia Blockchain’s MPC technology that can enhance digital identity with self-sovereign storage and private computation.

ESG principles and Web3

A significant addition to the conversations at the convention was the integration of ESG principles into Web3 technologies. Environmental, Social, and Governance factors are increasingly seen as essential components of sustainable and responsible business practices. Many Web3 projects and enterprises are actively incorporating ESG considerations into their strategies. This commitment to sustainability and ethical governance aligns with the broader global movement towards a more environmentally friendly, equitable, and responsible future.

One groundbreaking topic that garnered significant attention was the tokenization of carbon credits. Several Web3 projects are pioneering the digitization of carbon credits, which allows for more accessible and efficient trading and tracking of carbon emissions. By incorporating blockchain technology, Web3 is poised to revolutionize the way we combat climate change. This innovative approach facilitates transparency in carbon trading, encourages environmental responsibility, and furthers the cause of reducing carbon footprints.

Embracing interoperability

Interoperability emerged as a pivotal theme at the convention, underscoring the need for different blockchain networks and Web3 projects to work seamlessly together.

DelNorte — Increasing efficiency and combating corruption: the power of blockchain-based bureaucracy

 

Increasing efficiency and combating corruption: the power of blockchain-based bureaucracy

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.

Scalable DeFi

Scalable decentralized finance

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 and scalable blockchains

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.

Mechanism to guarantee fixed prices

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:

  • First movers that discover and, hence, secure fixed prices (lock-swap) have a minimal impact on other users’ ability to use the AMM solution.
  • The mechanism allows for completely independent execution across shards and blockchains to support unlimited scalability.

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.

Remove front-running opportunities

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.

Regulation and traditional finance

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:

  • First, front-running needs to be effectively addressed, and for the sake of the blockchain narrative, in a decentralized fashion, such as the privacy-preserving swapping on Partisia Blockchain.
  • Second, the built-in “free” arbitrage opportunities may not be acceptable for financial regulators. The proposed lock-swap is a simple add-on feature that can be switched off unlike the AMMs on Ethereum where free arbitrage is cooked into the very foundation of the blockchain platform.
  • Third, privacy-preserving computation may involve data that need to operate on nodes running in designated jurisdiction, which is a built-in functionality on the Partisia Blockchain.

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.
