Solicitante:

NCHAIN HOLDINGS LTD [AG]

US_2020204350_A1

Resumen de: WO2019043536A1

Trustless deterministic state machines can be implemented using a blockchain infrastructure and state machines can run concurrently over more than one blockchain transaction. The transactions can be done in a Bitcoin blockchain ledger. A unlocking transaction constraint that constrains a unlocking transaction to include a transaction input that references a previous transaction output is determined. A redeemable transaction is created to include a transaction output that includes an amount and a transaction locking script that includes the unlocking transaction constraint, with unlocking the amount being contingent upon execution of at least one unlocking script of the unlocking transaction satisfying the unlocking transaction constraint. The redeemable transaction is caused to be validated at a node of a blockchain network.

A first and second verification address (i.e. an address indicating a particular location on a blockchain) may be assigned to an individual having a previously verified identity, an identifier for the individual and biometric data of the individual is stored in the blockchain at the assigned first verification address and second biometric data, and possibly a second identifier, is stored at the second verification address. A request to verify an individual’s identity is received from a client-side device, the request containing a received identifier(s) and received biometric data, the request indicating the associated blockchain verification address(es). The stored identifier(s) and biometric data in the blockchain are retrieved from the specific address(es) and upon successful matching of the supplied and retrieved identifier(s) and biometric information and possibly also a supplied private key matching the associated private key, identity verification is successful, which may involve signing a verification possibly using the associated private key related to the verification address. Alternatively, an identity verification request from a second computing device may be verified. Users, different to the individual, have different access to the stored data based on their respective private keys.
