Solana has introduced the Solana Attestation Service (SAS) on its mainnet to establish a new standard for proving identity in Web3 ecosystems.
The protocol allows users to attach off-chain credentials to their wallets, such as KYC data, investor status, or jurisdictional information, in a cryptographically signed and reusable manner.
SAS is designed to be permissionless and open, enabling any developer or identity provider to integrate it without centralized gatekeepers.
By utilizing the SAS SDK, applications can conduct secure identity checks efficiently, aiming at scalability for capital markets and compliant apps on Solana's blockchain.
