Validators are similar to miners in that they verify transactions and ensure the network isn’t processing fraudulent transactions. Proof of stake means that, instead of relying on miners, individual users can stake a network’s native cryptocurrency and become validators. However, this process can be hugely energy-intensive, especially as the processing power used by miners that didn't solve the puzzle goes to waste. They are then rewarded with the network’s native cryptocurrency. The first miner to solve a puzzle adds a new transaction to the record of all transactions that make up the blockchain. In this system, miners use a machine’s processing power to solve complex mathematical puzzles and verify new transactions. Ethereum, like other cryptocurrencies such as Bitcoin, currently uses a proof-of-work consensus mechanism. With blockchains such as Ethereum, there is a need to validate transactions in a decentralized way.

How does proof of stake differ from proof of work? 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. How does Ethereum 2.0 differ from Ethereum?
#Serenity symbol upgrade#
The full upgrade to Ethereum 2.0 is expected to take place by 2023, according to the Ethereum Foundation. This also means that it will become much easier from a hardware perspective to run an Ethereum node, because there will be far less data that needs to be stored on a given machine. Instead of settling all operations on one single blockchain, shard chains spread these operations across 64 new chains. The final phase is shard chains, which will play a key role in scaling the Ethereum network. The second phase, called "the Merge," is expected in the second quarter of 2022 and will merge the Beacon Chain with the Ethereum mainnet. As the name suggests, it is a separate blockchain from the Ethereum mainnet. The Beacon Chain introduces native staking to the Ethereum blockchain, a key feature of the network’s shift to a PoS consensus mechanism. When is Ethereum 2.0 happening?Įthereum 2.0 is launching in several phases, with the first upgrade, called the Beacon Chain, going live on December 1, 2020. The name Ethereum 2.0 has stuck, however. Accordingly, Eth1 is now known as the "execution layer," where smart contracts and network rules reside, while Eth2 is referred to as the "consensus layer," which ensures that devices contributing to the network are acting in accordance with its rules. The rebrand is intended to reflect the fact that what's happening is a network upgrade rather than the launch of a new network. The upgrade aims to enhance the speed, efficiency, and scalability of the Ethereum network so that it can avoid bottlenecks and process more transactions simultaneously.īut Ethereum 2.0 also doesn't really exist-in January 2022, the Ethereum Foundation said it would stop referring to the upgrade as Ethereum 2.0. What is Ethereum 2.0?Įthereum 2.0, also known as Eth2 or “Serenity,” is an upgrade to the Ethereum blockchain.

The multi-phased upgrade aims to improve the Ethereum network’s scalability and security through several changes to the network’s infrastructure-most notably, the switch from a proof-of-work (PoW) consensus mechanism to a proof-of-stake (PoS) model. The long-awaited Ethereum 2.0 upgrade is near.
