On April 26, the Washington state governor signed SB 5638, which recognizes the validity of distributed ledger technology. Intending to expand the scope of the existing federal ESIGN Act, the bill adds a new chapter to the Revised Code of Washington, defining distributed ledger technology as “any distributed ledger protocol and supporting infrastructure, including blockchain, that uses a distributed, decentralized, shared, and replicated ledger.” The bill prohibits an electronic record from being denied “legal effect, validity, or enforceability solely because it is generated or stored using distributed ledger technology.” The bill is effective July 28.
