Zkopru: Innovating Privacy in Decentralized Transactions
Zkopru, an innovative protocol developed by a team focusing on privacy and scaling exploration within the Ethereum ecosystem, introduces optimistic roll ups coupled with zk-proofs to enhance transaction privacy and efficiency. By using nullifiers instead of inputs, Zkopru ensures unlinkability between transactions, enhancing anonymity within its UTXO model.
Building a Private Exchange within Zkopru
Zkopru envisions a private exchange platform where users can securely trade assets while maintaining compliance and privacy. This exchange utilizes blind signatures and social matching practices to facilitate anonymous trades, where sellers and buyers are seamlessly paired to ensure precise matching.
Integration with ERC-721 Tokens and Future Scaling Solutions
Zkopru team's future vision includes adapting Zkopru to support ERC-721 tokens and initiating potential modifications to its underlying circuit for enhanced privacy functionality. Additionally, plans to explore Plonk circuits and other advanced scaling methods like rollups showcase a commitment to continuous innovation.
Collaboration with Other Layer 2 Solutions and Predicted Evolution
Zkopru aims to collaborate and potentially integrate with various Layer 2 solutions, envisioning a future where interoperability among different rollups is embraced. While the current focus remains on Zkopru's unique privacy features, potential evolution may involve diversifying the circuit technology and adapting to changing Ethereum standards such as ERC-1155 tokens.
This week Anna chats with Wanseob Lim an Applied ZKP Developer in the Privacy & Scaling Exploration Team at the Ethereum Foundation and one of the authors of the Zkopru protocol. They explore how Zkopru uses optimistic rollups and zero knowledge proofs to create a privacy-focused Layer 2. Wanseob walks us through the transaction process and how the protocol is built to circumvent high gas fees. We also hear a little about what’s to come in the Zkopru ecosystem from merchandising to private exchange of NFTs.
Aztec aims to be the privacy layer for Ethereum. They believe that unlocking programmable privacy is the next frontier for blockchains. Aztec is the first zero knowledge rollup built from the ground up for anonymous payments and DeFi transactions.
