Distributed Ledger Technology

Distributed Ledger Technology Explained

By Heath Muchena | Decentralised News | 30 May 2021


A distributed ledger refers to a distributed record of transactions maintained through a consensus among a network of peer to peer nodes. A consensus is important for record-keeping. Before adding a fresh block to the chain, there are rules to follow. The most popular form of distributed ledger technology is the blockchain. The blockchain offers the foundation for cryptocurrencies as well as other applications.

Types of Distributed Ledger Technology

They are grouped into Permissionless and Permissioned.

  • Public/Permissionless

Under this category, anyone can access the ledger, and it is maintained through collaboration among nodes within the public network. Anyone is allowed to join the network and take part in a block verification process to create consensus. Good examples of permissionless platforms are the Bitcoin and Ethereum blockchains.

  • Private/Permissioned

This platform gets rid of members who may contribute to the system state consensus. Approved blockchains lack this feature. The good thing is that they allow quicker validation of transactions as well as boosted privacy.

Features of Distributed Ledger Technology

  • Pseudo-anonymity in the sense that they allow participation using only identifiers. However, private blockchains may lack this feature.

  • Transparency. Every member may view all the blockchain’s transactions even though they may be anonymous. This feature may also not be available in permissioned systems.

  • Immutability.

  • Block ordering guaranteed to prevent double-spends.

  • Decentralisation.

  • Replication and Synchronization of transactions across all the network nodes.

  • Integrity protection.

The functioning of the Distributed Ledger Technology

  • A distributed ledger is a connected list of sets of transactions between the network peers arranged according to time, and every peer has a copy.

  • For integrity and non-repudiation, a ledger-stored transaction is encrypted using a cryptographic key.

  • Transaction handling is shared among members.

  • It is maintained based on the consensus of the users. There is no central authority or storage.

  • The digital data is duplicated and shared among several physical nodes.

Platforms using Distributed Ledger Technology


This was the first distributed ledger, and it was aimed at creating Bitcoin’s core platform that maintains a public ledger for all Bitcoin transactions within the network. The Bitcoin blockchain solved the double-spending issue.


This platform supports an altered version of Bitcoin’s consensus mechanism that allows better block time during mining.

Hyperledger Fabric

This is an open-source platform. It can also be said to be a collaborative, distributed ledger technology that is a private blockchain. It has a modular architecture with plug and play modules for consensus mechanism and ledger services. 


This allows users to send money between one another. Its parent company created the Ripple payment protocol and exchange network.

Closing Remarks

The distributed ledger technology has brought to light the huge potential that will revolutionize a bunch of industries. Some of the qualities shown by distributed ledger technology are decentralization, trust, security, and the low cost of operations.

With its exciting features, distributed ledger technology is a natural tool for several complex distributed systems. All in all, the benefits that have come with Blockchain technology are amazing.
