Distributed Ledger Truth

Distributed ledger truth is the concept that the shared history of transactions across a network of nodes is the only source of reality. Because the ledger is distributed, every node has a copy, and they all agree on the state through consensus.

This prevents any single party from altering history or creating fake transactions. The truth is established through cryptographic proofs, such as digital signatures and hash chaining.

In the context of finance, this ensures that account balances and ownership records are immutable and transparent. It is a radical departure from centralized databases, where the "truth" is determined by a single entity.

Maintaining this truth is the primary function of a blockchain and the foundation for all decentralized financial activities.
