Oasis Labs

Oasis Labs has presented 1 V-Sum technical briefing. Oasis Labs demos on-chain verifiable credentials and selective disclosure on the Oasis confidential EVM. The thesis: put KYC/KYB data on-chain once with a trusted issuer (Equifax-rooted in this demo), then reuse it across web3 protocols without re-doing verification per counterparty — while giving users revocable, selective control over exactly what each verifier sees. The demo walks end-to-end through requesting a credential via identity.oasislabs.com, receiving both an NFT credential on the non-confidential Emerald chain and the full identity data stored confidentially on Sapphire (Oasis's confidential EVM, backed by trusted hardware), granting a demo website access to just the "is over 18" property, calling the isOver18 view from an Express backend, and revoking access afterwards. Broader use cases: credit score disclosure, zip-code mortgage / insurance quoting, and any flow that needs a derived fact rather than raw PII.
