What is Proof of Stake?

Proof of Stake: a crypto term, explained in plain English.

In one line

A way for a blockchain to agree on new blocks where validators lock up coins as a deposit instead of using mining power.

In simple words

Imagine a group project where the people who put down a deposit get to check the work. If they cheat, they lose their deposit.

That is proof of stake: trust comes from having something to lose.

The technical side

In proof of stake, validators are chosen to propose and attest to blocks in proportion to the coins they stake. Dishonest behaviour can be punished by slashing part of the stake. It uses far less energy than proof of work; Ethereum’s switch in September 2022 (the Merge) cut its energy use by more than 99%.

Solana, Cardano and most newer chains use proof of stake. Critics say it can favour the largest holders.

Proof of Stake kya hai?

Proof of stake mein woh log blockchain chalate hain jo apne coins lock karte hain. Dhokha diya toh coins kat jaate hain. Bijli bhi kam lagti hai.
