US Patent 11195177 Distributed ledger systems for tracking recurring transaction authorizations

In an example computer-implemented method executed by at least one processor, a first notification is received at a first computing system in a distributed computing network from a second computing system in the distributed computing network. The first notification identifies a first block in a distributed blockchain. The first block encodes authorization data describing a recurring payment authorization between a user and a merchant. The authorization data includes an account identifier associated with an account held by the user, and an identity of the merchant. The first block is obtained by the first computing system from the distributed computing network. The first block is decoded by the first computing system to determine an association between the user, the account, and the merchant.
