The Origin

Delegated Proof-of-Stake (DPoS) is a variation of the classic Proof-of-Stake (PoS) consensus mechanism.

A consensus mechanism is the core of every blockchain. It refers to how all the nodes in a decentralized network agree on the state of a blockchain.

While there are different kinds of consensus mechanisms, they primarily fall into two main categories: Proof-of-Work (PoW) and Proof-of-Stake (PoS).

In DPoS, participants elect delegates who validate blockchain blocks.

PoS evolved as a low-cost, low-energy consuming alternative to the PoW algorithm. This system incentivizes users to confirm data and ensure network security by rewarding them with native tokens. Now, it powers some of the most innovative and popular blockchains today, such as Ethereum.

But not all PoS blockchains work the same.

The specific implementations and workings of PoS can differ significantly between different blockchains. While the fundamental principle of PoS in different blockchains remains the same, their specific rules, protocols, and mechanisms can vary.

This is where Delegated Proof of Stake (DPoS) comes into the picture!

DPoS is a specific type of PoS consensus mechanism that features a voting and delegation mechanism to make the process more democratic.
