A blockchain is a decentralized and distributed digital ledger that is used to record transactions across many computers. As the transactions are stored in a decentralized way across the entire network of computer systems, altering or hacking any record on blockchain is difficult, which makes blockchain a perfect technology to store highly confidential data, for example, medical records, contracts, personal information, and so on.


As a leading provider of eSignatures, we always look for opportunities and technology to disrupt the eSignature industry. At API World 2021, Justin Johnson, a Seattle-based Web Developer at HelloSign will share how to write digital agreements on blockchain. His excitement around blockchain is rather recent, though he’s quickly become interested the innovation happening in both software and community organizing in the Web3 space. In his free time, Justin moonlights as a sound designer for theater shows, and enjoys creating art that lies at the intersection of technology and performance.

In this session, we’ll explore the topic of writing digital agreements to the blockchain and demo a working proof of concept that writes to the Polygon PoS (Proof of Stake) chain using open source tooling. We’ll have some time for questions at the end. If you are joining API World this year, we look forward to seeing you in our session at 10 AM Pacific Time on October 27.
