Decentralized electronic protocol signing platform EthSign is about to launch the full-chain proof protocol Sign Protocol, which allows users to freely prove and verify any information on the chain.

Proof is a digital signature of structured data used to establish more trust on the chain. Authentication is not a new concept, and countries such as Singapore and the United Arab Emirates have already launched nationally-funded online authentication services.

EthSign is fundamentally an application for proof, allowing users to prove their agreement to documents on the chain. The next step is to develop EthSign into a proof protocol that allows users to sign all content on the chain.
