Ethereum Developer Team Beiko announces the launch of Ethereum Merge Kintsugi testnet on Monday. The merger is Ethereum’s transition from proof-of-work (PoW) consensus to proof-of-stake (PoS) consensus, with the primary goal of maximizing the scalability, security, and sustainability of the Ethereum ecosystem. When Kintsugi has been updated and stable, the final journey from Ethereum to PoS (proof of stake) begins.
Over the past few months, client teams have worked tirelessly to implement a new set of merger milestones. Now they are live on a new testnet: Kintsugi 🍵!

Christmas came early🎄!

The Ethereum blockchain started several network updates this year to prepare for the biggest transition in the upcoming year 2022: Link. This update marks the official transition of the Ethereum blockchain to proof-of-stake consensus. At this point, the current Ethereum Mainnet (PoW) will merge with the Beacon Chain (PoS). The mainnet Merge, or Kintsugi, is expected to debut in Q1 / Q2 2022 and end Ethereum’s proof-of-work (PoW) consensus to finalize the next block.
According to Ethereum’s road map Scored by Ethereum co-founder Vitalik Buterin, The Merge is the next milestone followed by The Surge, The Verge, The Plurge, and The Splurge. Ethereum’s proof-of-work (PoW) chain has already rolled out network updates: Berlin, London, and Arrow Glacier.
Happy birthday beacon chain!
Here’s an updated roadmap diagram for where the Ethereum protocol development is and what’s coming in what order.

The Arrow Glacier network update delayed the EIP-4345 difficulty bomb until June 2022. This will push the difficulty bomb on the Ethereum PoW chain until next summer. The Ethereum community hopes to have “The Merge” activated on the mainnet before June 2022.
