Using private keys for document signatures, building a trust mechanism on the blockchain ft. Xin Yan, founder of Sign Protocol
EP.238
GM,
Have you ever used online signature services such as DocuSign or Dropbox Sign for digital document signatures? In the past, when people couldn't sign documents in person, they might ask the other party to sign and fax it back. Later on, many contracts and documents were digital files, and people could use electronic signatures to complete the signing process.
The theme of this podcast episode is a Web3 service called EthSign. It uses the wallet's private key for signatures. Blocktrend has invited Xin Yan, the founder of EthSign and Sign Protocol, to join us remotely and introduce the Web3 signature service. Before recording this episode, even though I had signed many documents or contracts myself, I had never seriously thought about the significance behind the signature. EthSign has been reported by the well-known tech media TechCrunch and has now integrated with LINE and Telegram, making it more convenient for users to use Web3 signature services.
In this episode, we discuss what Web3 signatures are, how they differ from Web2 digital signatures, and why such a signature mechanism is considered to build a trust mechanism on the blockchain. Perhaps, in the future, simply signing a name could reduce the collateral ratio for assets in DeFi borrowing from 110% to 90%. The difference in between is the value of trust.
This episode includes:
What is Sign Protocol? Are there similar services in Web2 or the physical world?
How to use Sign Protocol in Web3 for identity verification?
If Plaid and MaBao accounting can also use Sign Protocol for signing, what are the benefits?
How can on-chain signatures enhance the capital efficiency of DeFi?
What are the differences between EthSign and the Ethereum Attestation Service? Why not operate in a public goods manner?
In the past, one of the methods for verification was issuing NFTs. How does Sign Protocol differ from holding NFTs?
