(a) How many times has Bitcoin been “halved"?

The Bitcoin has been halved After every 210,000 blocks approximately after every four years the block reward is given to Bitcoin miners .The Bitcoin was last halved in November 2012 the block was cut into 25 BTC per block and in July 2016 the block was cut into half which is 12.5 BTC per block and latest in May 2020 It means that it was halved 3 times in past years.

(b) When is the next expected?

Since, Bitcoin was last halved in November 2012 and then in July 2016 and newest in May 2020 so according to me it should be halved in spring 2024.

(c) What is the current amount that Bitcoin miners achieve?

(2). What is a consensus mechanism?How are Proof-of-Work and Proof-of-Staking different?

Ans: The consensus mechanism is a type of mechanism or computer algorithm which is used in computer and blockchain systems to achieve every new transaction data entered in blockchain systems.In Bitcoin blockchain the consensus the consensus mechanism is knows as Proof-of-work (POW).The another common consensus algorithm that is evolved as low cost also low energy consuming algorithm to POW is proof-of-stake (POS).

Let's understand Proof-of-work (POW) consensus mechanism.

The Proof-of-work (POW) is like common consensus algorithm which can be used by the popular cryptocurrencies for ex- Bitcoin & litecoin. This is said to be a system that is generating old coins like Bitcoin. It is mainly used for mining of the first generation of coins.It allows a participant to prove that the work done and submitted by them should qualifies them to get the right to add a new transactions in the blockchain.

Let's have a look on Proof-of-staking (POS) consensus mechanism.

It is the consensus algorithm which is a type of set of rules governing a blockchain network and creation of native coin .(POS)consensus mechanism have same objectives like (POW) consensus mechanism in one line it is a instrument to achieve consensus.As we know that miners are involved in (POW) but in (POS) no miners are involved .

Difference between Proof-of-Work and Proof -Of -Stake .

With proof of stake the maners can validate and mine tranjactions of blocks which is based on amount of coins .Proof of work (POW) mining needs a large amount of energy consumption of fuel ; Proof Of Stake (POS) gives mining power which is based on the percentage of the coinds held by the miner. Also proof of satke is less risky if we talk about the potential of miners to attack or harm the network as it structures compensation which makes an attack less advantageous for the miners.
