Abstract: A computer implemented method for maintaining a synchronized distributed ledger data structure across a plurality of computing nodes each configured to enforce a synchronization protocol for coordinating updates of the synchronized distributed ledger data structure to establish an inter-group reconciliation mechanism across one or more trusted entities having immutable transaction records stored in the form of blockchain data structures recording approvals from one or more parties corresponding to the plurality of computing nodes. In some aspects, regulator nodes are contemplated.

Abstract: An approach for coordinated transaction messaging using a cross-border blockchain platform is described in various embodiments. A blockchain backend data structure, stored across a set of distributed computing nodes provide better transparency of cross border payments and Nostro accounts as such payments are processed through the network of correspondent and beneficiary banks. Correspondents and beneficiary banks record key states of payments transactions and Nostro balance movements directly to the blockchain providing improved payment state transparency.
