AntChain Integrates Zero-Knowledge Proof for Enhanced Privacy and Verification in Web3.0 Era

Ant Group’s AntChain has announced a new architecture upgrade for its privacy collaboration platform, AntChain FAIR, introducing Zero-Knowledge Proof (ZKP) as a core technology for verifiable computation. This extends trustworthy data transfer to the verification of computation processes, data attributes, and identities.

ZKP is a cryptographic technique that enables one party (the prover) to demonstrate to another party (the verifier) that they are aware of a value or hold specific knowledge without disclosing any specifics about the information or value itself.

ZKP is seen as one of the most crucial technologies for the next five years in the Web3.0 era. It allows a prover to convince a verifier of the truth of a statement without revealing any additional useful information.

The integration of Ant’s AI security detection platform “Yijian” and Ant’s privacy computing platform “Yinyu” is seen as a significant future trend. Large-scale AI model training requires a lot of data, and these data need to go through privacy computing to ensure safety and reliability.

Companies and institutions adopting ZKP architecture can ensure that the entire process of data computation is carried out according to agreed conditions, is correct, and can be verified, all while maintaining privacy. This will greatly enhance the credibility of identity verification, AI model training, data transfer, asset transactions, and on-chain and off-chain collaboration, accelerating the penetration of Web3.0 into more complex industrial scenarios.

AntChain has optimized software algorithms to accelerate the “proof generation” phase to 2.8 times the original baseline. This phase involves generating a “proof” for data, identity, computation process, etc.

To lower the threshold for using ZKP, AntChain FAIR has introduced zkWASM, a new type of ZKP virtual machine, into its trusted computing architecture. This allows for instruction-level verifiable features and supports the conversion of algorithm programs written in various front-end languages without the need to understand complex underlying algorithm details.

AntChain FAIR is a privacy collaboration platform for data transfer, combining the advantages of blockchain and privacy computing. It resolves the natural contradiction between data sharing and privacy protection in the data flow process. It is currently being used in several data exchanges, including the Hangzhou International Digital Trade Center and the Guizhou Big Data Exchange.

NEAR and Polygon Partner to Launch zkWASM

The NEAR Foundation and Polygon Labs have announced a collaborative effort to develop a zero-knowledge (ZK) prover for Web Assembly (WASM) blockchains. This initiative, termed “zkWASM,” is poised to bridge the gap between WASM-based chains and the Ethereum ecosystem, as revealed in a joint announcement on November 8, 2023.

zkWASM stands as a revolutionary prover in the realm of blockchain technology. It aims to enable WASM-based networks to integrate seamlessly into the Polygon ecosystem, marking their first-ever participation. The primary motivation behind the creation of WASM, a binary instruction format, was web browsers. However, its utility has expanded to potentially serve as a compute engine for blockchain networks, offering an alternative to the Ethereum Virtual Machine (EVM).

The integration of zkWASM into Polygon’s Chain Development Kit (CDK) is a pivotal aspect of this collaboration. The CDK empowers developers with tools to create customized blockchain networks based on their specific needs. With the inclusion of zkWASM, developers will gain the capability to design WASM networks and incorporate them into the broader Polygon ecosystem, which includes the Ethereum mainnet itself.

This partnership signifies a major step for NEAR in its integration with the Ethereum network. Illia Polosukhin, co-founder of NEAR Protocol, emphasized that “NEAR is integrating more with Ethereum by innovating in new research frontiers, and the shared expertise of NEAR and Polygon will expand the ZK landscape and defragment liquidity across chains.” This approach is expected to improve liquidity for users and enhance the overall efficiency of the NEAR network.

One of the most significant advantages of the zkWASM prover is its impact on NEAR validators. By employing the zero-knowledge proof method, the computational overhead involved in confirming a shard is significantly reduced. This reduction in computational demand is projected to lead to “better scalability and increased decentralization” for the NEAR network, according to the joint statement.

Polygon is concurrently working on developing a multichain ecosystem, known as “Polygon 2.0.” This new system will feature bridges operating on zero-knowledge proof-based transition mechanisms, facilitating the transfer of assets across different chains.

The development and expected launch of zkWASM next year marks a significant leap towards creating a more secure, interoperable, and scalable Web3 ecosystem. This partnership between NEAR and Polygon exemplifies the collaborative spirit in the blockchain community, driving innovation and integration across different platforms and technologies.
