Decentralized Ledger Technology (DLT): The Precursor to Blockchain
Decentralized Ledger Technology (DLT) is the foundation of blockchain. It refers to systems that record data across multiple locations without a central authority. DLTโs principles include transparency, security, and decentralization, which paved the way for blockchain.
DLT enabled distributed record-keeping, allowing multiple participants to maintain a shared ledger. This eliminated the need for a central intermediary, reducing costs and increasing trust. These features inspired the creation of blockchainโs immutable and decentralized structure.
Before blockchain, other DLT systems emerged. Hashgraph, for example, used a consensus algorithm for fast, secure transactions. Directed Acyclic Graphs (DAGs), like IOTAโs Tangle, offered scalable, fee-less alternatives to traditional ledgers. These systems showcased the potential of decentralized record-keeping.
DLTโs innovations directly influenced blockchain. By proving that decentralized systems could work, DLT inspired Satoshi Nakamoto to create Bitcoin. In recent times, decentralized ledger technology has evolved, powering new technologies and expanding blockchainโs possibilities. The history of DLT highlights its role as the precursor to blockchainโs revolutionary impact.
