Current systems for data authentication, such as in the course of financial transactions to comply with anti-money laundering and know-your-customer legislation, are burdensome and inefficient for banks and their clients. A platform of some embodiments provides a system for utilizing distributed ledger technologies, such as a blockchain data structure residing on a distributed ledger. A client may use this blockchain data structure to register the client's personal information in a data object that then may be routed to specific identified trusted individuals who verify that the information in the data object is correct. Once verification is complete, the client or other trusted individuals may use the data object as necessary to register the client for various programs or services, such as additional bank services.
