Decentralized electronic signature: EthSign leads the evolution of the next generation signature protocol! Why can't this change be ignored?

In today’s wave of paperless office and remote work, electronic signatures have become an irreversible trend. However, traditional electronic signatures have risks of centralized custody. In order to solve this problem, EthSign, a decentralized electronic agreement signing platform, announced that it will launch an innovative technology - "Sign Protocol". "Sign Protocol" is a full-chain certification protocol based on blockchain technology, designed to improve the information certification and verification process. By using blockchain technology, "Sign Protocol" ensures the security and non-tamperability of information during the signing process. This means that both signers and verifiers can confidently use the protocol to electronically sign without worrying about the risk of information being tampered with or leaked. The launch of this agreement will bring major changes and breakthroughs in the field of electronic signatures. It can not only improve the security and reliability of signing, but also simplify the signing process and reduce labor and time costs. In addition, due to the decentralized architecture, "Sign Protocol" can also Innovative technology to establish trust mechanism on the chain. While the concept of digital authentication is not new, some countries such as Singapore and the United Arab Emirates have implemented digital signatures through state-sponsored online authentication services. However, EthSign's pioneering work is to extend the application of digital signatures to other blockchain platforms such as Bitcoin, TON and Solana, which will bring more meaning and value to digital signatures. Through Sign Protocol, EthSign is committed to building a more powerful on-chain trust mechanism to provide users with more secure and reliable digital signature services.

How does EthSign do it? In a blockchain system, each piece of data has a unique fingerprint, called a hash value. Looking deeper, EthSign works by capturing the hash of an uploaded document and inviting designated signers to sign their consent to that hash using their private keys from their wallets. We can then use the original hash and the signer's public key to verify this cryptographic approval and the integrity of the file.

In terms of data availability layer, zkAttestation technology provides EthSign with a unique user authentication method. The technology allows users to simply prove that they have used DocuSign's electronic signature services in the past without revealing any personal information. This method not only protects user privacy, but also simplifies the authentication process. It no longer requires EthSign to request a customer list from DocuSign. Through zkAttestation, EthSign is able to verify users' past behaviors without having to expose personal identities, which provides users with higher privacy protection and a convenient authentication experience.
