Ethereum Inches Closer to the Merge With Sepolia Testnet Launch
The top smart contract blockchain completed its Sepolia testnet for “the Merge” Wednesday, bringing the network another step closer to its long-awaited transition to Proof-of-Stake.
Seoplia is Ethereum’s second public Merge testnet, following a successful deployment on Ropsten last month. Next up, the update is set to launch on the Goerli testnet, before it heads to Ethereum mainnet. Though the shipping date for the Merge on mainnet has not yet been finalized, the Goerli launch is expected in the coming weeks.
The Merge refers to the docking of Ethereum’s Proof-of-Work execution layer and its Proof-of-Stake consensus layer, which is also known as the Beacon Chain. In each of the testnets, the two layers have merged as part of a move to replace Ethereum’s Proof-of-Work consensus mechanism with Proof-of-Stake. Once the mainnet launches, Ethereum will no longer be reliant on miners and instead use validators who have staked ETH to achieve consensus. Running an independent node requires locking up 32 ETH worth about $35,000 at current prices, though staking projects like Lido and RocketPool have brought pooling services to the market for those with less capital to deploy.
The Merge is a highly anticipated event for Ethereum as it’s expected to reduce ETH emissions while improving the network’s energy efficiency by over 99%. It will also set the stage for the addition of shard chains, the next phase in Ethereum’s scaling ambitions alongside the adoption of Layer 2 solutions like ZK-Rollups.
