On July 8, at the 2023WAIC Global blockchain Industry Summit Forum, Ant chain announced a new architecture upgrade for privacy collaboration platform AntChain FAIR, introducing verifiable computing technology with zero knowledge proof (ZKP) as its core, extending from trusted data flow to verifiable computing processes, data attributes, and identities. It is understood that this is an important upgrade for the core architecture of the FAIR platform after upgrading its large-scale computing capacity last year, and it is also a continuous breakthrough of the ant chain in the field of Web3 technology.

Zero knowledge proof is regarded by the industry as one of the most critical technologies of Web3 in the next five years, which means that the verifier can convince the verifier that a claim is correct without providing any useful information to the verifier. Compared with privacy computing, which emphasizes data analysis and calculation on the basis of protecting data privacy, zero-knowledge proof is characterized by "verifiability".

On the basis of privacy protection, enterprises and institutions that adopt zero-knowledge proof architecture can ensure that the whole process of data computing is carried out in accordance with the agreed conditions, correct and verifiable, which will greatly improve the credibility of the whole process, such as identity authentication, AI model training, data flow, asset trading, chain-on-chain and off-chain collaboration, and accelerate the penetration of Web3 from the digital world to more complex industrial scenarios. In recent years, with the rapid development of zero-knowledge proof at the basic protocol and hardware acceleration level, this technology has gradually been able to deal with complex tasks such as neural network reasoning.

It is understood that the ant chain is fully autonomous and controllable in the field of Web3 technology, and the authorized patents such as block chain and private computing are the first in the world. As the earliest manufacturer of layout Web3 technology in China, Ant chain has independently developed and launched iconic products such as blockchain and service BaaS, blockchain all-in-one machine, blockchain communication network BTN, blockchain storage engine LETUS, large-scale open architecture HOU, cross-chain ODATS and other iconic products, widely covering Web3 infrastructure.

Wei Changzheng, a senior technology expert at Ant chain, said: "Privacy and verifiability have always been important topics in the field of data and computing, and there are similarities and essential differences between them. Zero knowledge proof has efficient verifiability, coupled with the ability to protect specific data from being seen by the verifier, so it meets the dual needs of privacy and verifiability to some extent."

The key link of zero knowledge proof is the "proof generation stage", that is, to generate a "proof" for data, identity, calculation process and so on. It is understood that the ant chain through the software algorithm optimization, "proof generation" end-to-end acceleration of the original baseline 2.8 times.

In addition, the above-mentioned characteristics of zero-knowledge proof can also "compress" computation and data. The typical application of block chain is to transfer the computing task to the chain, and use zero-knowledge proof to prove that the actions under the chain are verifiable. Only let the proof results be stored and verified on the chain. For example, block chain platforms such as Yitaifang use zkRollups based on zero knowledge proof to effectively solve the problem of shortage of chain resources.

It is understood that in order to reduce the threshold for the use of zero-knowledge proof, Ant chain FAIR has added zkWASM--, a new zero-knowledge proof virtual machine, to the trusted computing architecture to achieve the provable feature at the instruction level, and can rely on WASM multi-language ecology to prove and transform algorithm programs written in a variety of front-end languages without paying attention to the underlying complex algorithm details and improving the friendliness of development applications.

FAIR is a privacy cooperation platform launched by Ant chain for data flow, which combines the advantages of block chain and privacy computing. The cooperation process is driven by intelligent contract, data flow is solved by privacy computing engine, and rights are confirmed by block chain technology. Registration and transaction consensus. It can solve the natural contradiction between data sharing and privacy protection in the process of data circulation. At present, FAIR has been applied in many data exchanges such as Hangzhou Digital Exchange and your Institute.
