Distributed Ledger Technology (DLT)

Distributed Ledger Technology (DLT) is a digital system for recording, sharing, and verifying information across a network of computers without a central administrator. Unlike a traditional database managed by a single organization, a distributed ledger is maintained simultaneously by many participants — each holding a copy of the same data. When new information is added, it must be validated by the network through a consensus mechanism before being appended, ensuring that all copies remain consistent and that no single party can unilaterally alter the record.

Blockchain is the most well-known form of DLT, but it is not the only one. Other DLT architectures — such as directed acyclic graphs (DAGs), used by networks like IOTA — organize data differently but share the core property of decentralization and distributed verification. DLT is being explored across many industries beyond finance, including supply chain management, healthcare record keeping, voting systems, and digital identity, wherever there is a need for transparent, tamper-resistant shared records.

In the context of cryptocurrency and trading, DLT is the foundational technology that enables trustless transactions between parties who do not know each other. It eliminates the need for a central clearinghouse or custodian, reducing counterparty risk and enabling peer-to-peer exchange of value. For traders, the properties of the underlying DLT — including transaction finality, speed, and cost — directly affect the performance and feasibility of different trading strategies.
