Appearance of proof of stake

The principle of Proof of Stake

The Proof of stake (PoS) principle was introduced in 2011 on the Bitcointalk forum. It was created as a solution to the Proof of Work issues, by removing the concept of mining.

Definition of Proof of Strake

The purpose of Proof of Stake is to process transactions and create new blocks in the blockchain.

It is made network of validators, who must stake coins to validate the blocks of the blockchain.

Thus, the principle of Proof of Stake consists in putting a part of the tokens at stake, i.e. one’s possessions, in order to validate a block.

Le but de Proof of Stake est de traiter les transactions et créer de nouveaux blocs dans la blockchain
