Patent ID: 11818271

Abstract:
The invention relates, in general, to the field of computer engineering and, in particular, to arranging and storing information in the form of interlinked transactions in a distributed computer framework. The technology for linking transactions is provided. Transactions include information on public keys, as well as credentials of owners of these public keys. Public keys which belong to one owner are linked into a logical chain at the level of transactions. Each transaction contains information on one public key. Transactions are signed by a digital signature. Transactions are preliminarily placed into a specialized pool, then they are retrieved from the pool, verified, and, upon successful verification, data form the transactions is placed into a public ledger (blockchain). The verification comprises verifying the digital signature and confirming linkability or, in other words, confirming that a transaction belongs to a particular chain. Anyone having access to the ledger can perform all the necessary verifications. The invention provides decentralized storage and management of public keys, thereby enabling to minimize risks inherent to the commonly known centralized approach.
