Abstract: A computer implemented approach is proposed as a computer infrastructure that is configured such that users can access digital resources managed by an institution, using self-custodied cryptographic material. The cryptographic approach allows them to prove their identities, encrypt data, and decrypt data through specific computer interactions based in cryptography. A dynamic approach to cybersecurity is proposed using an adaptive cryptographic verification approach using a combination of multi-party cryptography techniques and opportunistic idle computing resource usage.

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.
