Abstract: In certain embodiments, blockchain-based validation of a bearer of a private key used to register a record on a blockchain may be facilitated. In some embodiments, reference information associated with a user and with a blockchain record may be obtained. The reference information may be based on a blockchain address associated with the user and with the record. The blockchain address may be based on a public key corresponding to a private key used to register the record, where the keys are a key pair associated with the user. A smart contract may be caused to be generated based on the reference information and provided on a blockchain. The smart contract may be configured to automatically validate a transaction using the public key. A notification indicating that the user registered the record may be obtained responsive to the smart contract validating a transaction signed using the private key.
