What are consensus mechanisms in blockchain and cryptocurrency?
Consensus mechanisms are protocols which secure the blockchain network against malicious attacks. Consensus protocols ensure that all nodes in the blockchain are on the same page and agree on the validity of some data. In this article, we will discuss what consensus mechanisms are used for, why they're important for cryptocurrency networks and how they work.
Consensus Mechanisms in Blockchain
Consensus mechanisms are the way that blockchain networks agree on shared rules. They're used to prevent double spending and other fraudulent activities, and they also help to ensure that no one person can control the network.
There are many different types of consensus mechanisms, but they all essentially serve the same purpose: coming to an agreement amongst a group of people or computers that want to do something together (like send money). Each type has its own advantages and disadvantages, but most fall into one of proof-of-work (PoW) or proof-of-stake (PoS).
Proof of Work: How It Works
The Proof of Work mechanism is the most common consensus mechanism in cryptocurrencies. It's also used by several blockchain projects that don't operate on a cryptocurrency basis, including Ethereum and Ripple.
In a nutshell, PoW involves miners competing to solve cryptographic puzzles in order to add new blocks onto the chain and thus earn rewards in terms of new coins or tokens. This process can be thought of as similar to how people compete on "Jeopardy!" or "Who Wants To Be A Millionaire?"--but with computers instead of humans playing against each other!
Proof of Stake (POS)
Proof of Stake (POS) is a method of achieving distributed consensus through the creation of new blocks in a blockchain network. In proof-of-stake, instead of requiring some work from the service provider, we require something that has value - like cryptocurrency.
Proof-of-stake (POS) is an alternative to Proof of Work (PoW), which was introduced as an alternative to Proof-of-Work and was designed to address its centralization issues. The idea behind POS is that instead of miners competing against each other for block creation rights, validators would be chosen based on their stake in the network -- i.e., their ownership stake in cryptocurrency -- and these "forgers" would have their earnings determined by how much they have invested into their staking pool/wallet/etc.
Proof of Elapsed Time (POT)
Proof of Elapsed Time (POT) is a new consensus mechanism that was introduced in the Burst blockchain. It's based on the idea of "last-writer-wins", which means that whoever writes their transaction first becomes its validator.
This alternative to traditional Proof-of-Work and Proof-of-Stake mechanisms has some advantages.
Fast processing speed: Transactions are validated only after they are written to the blockchain, so there's no need for mining or staking; there are no transaction fees either! You can send your coins whenever and wherever you want, without having to wait for them to be confirmed by miners before being able to use them again later on down the road if need be.
A consensus mechanism is a process by which a cryptocurrency network agrees about shared rules.

The most common consensus mechanism is proof of work (PoW), where miners compete to solve complex mathematical problems and the first one to find the solution gets rewarded in coins. This process is called mining and it uses computing power to verify transactions on the blockchain.
A newer type of consensus mechanism known as proof of stake (PoS) requires users who hold tokens in their wallets to validate blocks on the blockchain instead of actually mining them using hardware equipment like GPUs or CPUs. With this method, users can earn rewards simply by owning coins and locking them up during an initial period (staking). Staking takes place when nodes vote on which blocks should be added next based on their stakes; if you have more tokens than other nodes then your votes will have more weight than theirs do!
