In a world with out permission, that is a hard query. Blockchain was not truly constructed for entry management. They have been constructed to say sure to anybody with a non-public key.
However as cryptography has more and more conflicted with our small non-bubble lives, the necessity for permission has turn out to be inevitable. Who’s sufficiently old to enter? Who lives in the correct nation? Who has permission to vote, and what number of occasions? Who’s not a bot?
For a very long time, the one reply has been obtained from a one-time consumer circulate that traps developer groups on a walled KYC platform or upkeep purgatory. All dapps that wish to verify their credentials will find yourself rebuilding the identical weak backend a number of occasions, and customers will recreate the correct to entry at each door.
Many builders are engaged on this at present, however right here within the Solana land there may be one answer that has seen a variety of speak, particularly lately. The Solana Attestation Service (SAS) is a brand new open protocol to show off-chain information into reusable, verifiable claims that keep on with your pockets like a passport stamp.
Basically it gives a common layer for issuing and checking identity-based credentials. Issuers comparable to KYC suppliers, DAOS, employers, and even governments can write a signed certificates on the Solana Pockets handle that may show one thing like “I am over 18”, “I dwell within the US”, “I handed this DAO verification course of”.
Dapps doesn’t want to save lots of or double-check that knowledge. Simply verify the stamp.
Typical proofs embody pockets addresses, claims (comparable to “licensed”), metadata (non-obligatory), and signatures from the writer. Solana will show Onchain and retailer what might be queried and verified in a single SDK name.
There is no such thing as a server, consumer knowledge, or customized logic. Belief us on the quick path to belief, complexity and compliance.
Privateness presents (no on-chain private data), frictionless (use as soon as, wherever), no permission (to permit anybody to construct), smoother, safer, and extra difficult consumer expertise.
