Ethereum 2.0 with the transition to proof-of-stake

Ethereum 2.0 ou “Serenity”

Ethereum 2.0, également connu sous le nom de Eth2 ou “Serenity”, est une mise à niveau de la blockchain Ethereum, which aims to improve scalability and make the network more efficient.

The update will see the Ethereum network switch from a proof-of-work consensus mechanism to a proof-of-stake one, meaning that instead of using miners who make each other competition to check the transactions et les ajouter à la blockchain, les détenteurs de jetons d’éther peuvent voter pour des validateurs (également appelés nœuds de validation) qui apportent leur puissance de calcul pour traiter les transactions et sécuriser le réseau. Ces validateurs seront récompensés par des jetons ether pour la vérification des transactions. Le passage du mécanisme de consensus “proof-of-work” au mécanisme “proof-of-stake” devrait rendre Ethereum plus rapide, plus sûr et beaucoup plus évolutif qu’auparavant.

Proof-of-stake

While Ethereum 1.0 uses a consensus mechanism known as proof-of-work (PoW), Ethereum 2.0 will use a proof-of-stake (PoS) mechanism.

Proof-of-stake is a consensus algorithm that replaces the proof-of-work consensus algorithm. In the proof-of-work model, miners use their processing power to verify transactions, but in the proof-of-stake model, miners use their processing power to verify transactions. users bring their own pieces into play.

Ethereum requires decentralized validation of transactions. Ethereum, like other crypto-currencies such as bitcoin, currently uses a proof-of-work consensus mechanism. This means that miners use the processing power of a machine to solve complex mathematical puzzles and verify new transactions. The first miner to solve a puzzle adds a new transaction to the record of all the transactions that make up the blockchain. He or she is then rewarded with the crypto-currency network. However, this process can be very energy-intensive, as the processing power used by miners who haven't solved the puzzle is wasted. Proof-of-stake means that, instead of relying on miners, individual users can invest their own coins and become validators.

The benefits of Ethereum 2.0

• The proof-of-stake model enables faster transactions and lower fees than the previous proof-of-work model.
• Le modèle de preuve d’enjeu permet aux détenteurs d’Ethereum de “mettre en jeu” leurs avoirs dans des “pools d’enjeux” qui gagneront des récompenses et augmenteront leurs avoirs au fil du temps.
• Ethereum holders can now stake their assets on a number of popular exchanges such as Kraken, Coinbase and Binance.
• Ethereum 2.0 mettra en œuvre une méthode connue sous le nom de “sharding”, qui augmentera considérablement la vitesse des transactions, en portant potentiellement sa capacité à 100 000 transactions par seconde ou plus.
• The current cost of transactions on the Ethereum network is very high and prevents many people from using it.
• If this upgrade is successful, the resulting reduction in costs will make the network more convenient for average users.
• Ethereum's upgrade could have a profound effect on its pricebecause its lower costs and faster transactions open up the network to a larger number of users.
