Cease proper there. Corridor move?
In a permissionless world, it’s a clumsy query. Blockchains weren’t actually constructed for entry management; they have been constructed to say sure to anybody with a non-public key.
However as crypto collides increasingly with life outdoors our little bubble, the necessity for permissions has change into unavoidable. Who’s sufficiently old to enter? Who lives within the appropriate nation? Who has permission to vote, and what number of instances? Who isn’t a bot?
For too lengthy, the one solutions have come from walled-off KYC platforms or one-off person flows that entice dev groups in upkeep purgatory. Each dapp that wishes to examine a credential finally ends up rebuilding the identical brittle backend time and again, and customers get caught re-proving their proper to entry at each door.
Many builders are engaged on this immediately, however right here in Solana land, there’s one resolution particularly that’s seen a whole lot of buzz of late. The Solana Attestation Service (SAS) is a brand new open protocol for turning off-chain information into reusable, verifiable claims that follow your pockets like a passport stamp.
Primarily, it affords a common layer for issuing and checking identity-based credentials. Issuers, like KYC suppliers, DAOs, employers and possibly even governments, are actually in a position to write signed attestations to Solana pockets addresses that may show issues like “I’m over 18,” “I stay within the US” or “I handed this DAO’s verification course of.”
Dapps don’t must retailer or recheck that information — they simply confirm the stamp.
A typical attestation features a pockets tackle, a declare (like “is accredited”), metadata (non-obligatory) and a signature from the issuer. Solana shops that proof onchain, the place it may be queried and verified with a single SDK name.
There is no such thing as a server, no person information and no customized logic. Simply belief, composability and a speedy path to compliance.
It’s privacy-preserving (no private information onchain), frictionless (attest as soon as, use in all places) and permissionless (it’s open, so anybody can construct with it), leading to a smoother, safer, extra composable person expertise.
