Distributed Ledger Technology (DLT)
Distributed Ledger Technology (DLT) is a system in which multiple computers maintain a single digital ledger together. This means there isn’t one central organization managing all the data.
What is distributed ledger technology?
A digital ledger is a record of data, such as transactions. With DLT, many computers, also called nodes, each store a copy of that record.
When new information is added, the network checks whether it’s valid. The computers have to agree on it. This is called consensus. The new information is then added to all the copies.
A blockchain uses DLT. In a blockchain, verified transactions are stored in groups called blocks.
An example of distributed ledger technology
Imagine sending crypto to someone. The network checks the transfer. If the network approves it, the transaction is added to the digital ledger.
The nodes then update their own copies. This means the same information isn’t stored on just one server, but on many computers.
Why is distributed ledger technology important in crypto?
DLT is the technical foundation of many crypto networks. It makes it possible to process transactions without a central party, such as a bank, managing the ledger. Some networks also use DLT for smart contracts: programs that automatically carry out agreements when preset conditions are met.
News about a blockchain may cover changes to the network, validators, or how consensus is reached. These developments can affect how transactions are checked and processed.
DLT also has limitations. Some networks can become slower or more expensive under heavy use. Systems that use Proof of Work can consume a lot of energy. Also, data on a blockchain generally can’t be reversed. So a mistake, such as sending crypto to the wrong wallet address, may be permanent.
