Ethereum is transitioning from proof-of-work to proof-of-stake through The Merge, which requires the Bellatrix upgrade on the Beacon Chain first. The proof-of-work chain will then migrate to proof-of-stake when a specific Total Difficulty value is reached, with the Bellatrix upgrade scheduled for epoch 144896.
All Ethereum execution clients now support partial history expiry per EIP-4444, allowing users to reduce node storage requirements by 300-500 GB by removing pre-Merge block data. This represents a significant infrastructure improvement while full rolling history expiry development continues.
A security threat that existed on the Ethereum network from the Merge until the Dencun hard fork has been disclosed, with the vulnerability specifically manifesting during the Sepolia incident. The disclosure highlights a previously unknown attack vector that could have potentially compromised network security during this critical period.
The Ethereum Merge is approximately 20 days away, with mainnet client releases now available for upgrade. A Merge Data Challenge has been launched to encourage data collection, analysis, and visualization of the transition.
Ethereum's final testnet merger is announced as Goerli will merge with Prater, retaining the Goerli name post-merge. The Bellatrix upgrade preparing Prater for the merge is scheduled for epoch 112260 at 12:24PM UTC on August 4, 2022.
Ethereum's Ropsten testnet has set a Terminal Total Difficulty (TTD) of 50000000000000000 for its transition to Proof-of-Stake. Stakers and node operators must manually configure their execution and consensus layer clients before June 7, 2022.
Ropsten testnet became the first longstanding Ethereum testnet to undergo The Merge transition. A new Ropsten Beacon Chain was launched on May 30, 2022, with the network scheduled to upgrade to merge-compatible protocol rules (Bellatrix) at slot 24000 on June 2, 2022.
The Kintsugi merge testnet launched in December has successfully tested Ethereum's transition to proof-of-stake through various test suites and multi-client implementations. The testing phase has resulted in stable protocol specifications, with clients now having implemented the necessary changes for The Merge.
Ethereum client teams have launched Kintsugi, a public testnet for the Ethereum merge, following four previous development networks. This represents continued progress toward Ethereum's transition from proof-of-work to proof-of-stake consensus mechanism.
Ethereum's transition to proof of stake through The Merge is approaching with devnets being deployed and specifications finalized. The upgrade is designed to minimize impact on end users, smart contracts and decentralized applications while transitioning the network's consensus mechanism.
A recent paper describes three potential attacks on Ethereum's proof-of-stake algorithm, but researchers have identified a technically-simple mitigation that will be implemented before the Merge. The attacks are considered serious but will not delay Ethereum's transition timeline.
The Rayonism hackathon launched earlier this year to prototype Ethereum's transition to proof of stake, known as The Merge. The transition will merge the existing beacon chain (eth2) and execution layer (eth1) clients, with the beacon chain driving the merged system.
Ethereum's Altair upgrade epoch has been finalized with mainnet client releases in progress. The Merge interoperability specification has been released, with development networks (devnets) planned to follow as Ethereum moves closer to its proof-of-stake transition.
Ethereum's London upgrade is ready for deployment with merge checklist and draft EIP finalized. Altair devnets have launched as clients prepare for mainnet implementation of consensus layer improvements.
Ethereum is transitioning to Proof-of-Stake consensus mechanism in the upcoming months, which will reduce its energy consumption by approximately 99.95%. The Beacon chain has been operational for several months, providing real-world data on the energy efficiency improvements from the merge.
The article argues that zkEVM (zero-knowledge Ethereum Virtual Machine) should become the Ethereum ecosystem's new collective rallying point, similar to how 'The Merge' previously unified the community. The author suggests that zkEVM adoption could boost ecosystem morale, narrative control, and ETH price performance.
The article provides a recap of the Edelweiss Interop event, highlighting significant progress made by protocol developers across multiple Ethereum improvement areas following The Merge. Key development areas include withdrawals, danksharding, EOF, verkle tries, history expiry, and SSZ implementations.
The Ethereum Foundation shares updates from supported teams and developers who achieved significant milestones in 2022, marking it as 'the year of the Merge'. The roundup highlights accomplishments from various Ethereum ecosystem contributors and development teams working on research and development initiatives.
The Sepolia testnet will undergo a post-merge execution layer upgrade at block 1735371 on August 17, 2022. The upgrade will disconnect EL clients that haven't transitioned to proof-of-stake, requiring Sepolia node operators to take action.
Sepolia testnet announced as the second of three public testnets to undergo The Merge transition from proof-of-work to proof-of-stake. The network will transition when total difficulty exceeds 17,000,000,000,000,000, with updated client releases for go-ethereum and Erigon modified on July 5, 2022.
Ethereum is deprecating several testnets including Ropsten, Rinkeby, and Kiln following the network's transition to proof-of-stake. The Gray Glacier upgrade was scheduled for block 15,050,000 in June 2022, with testnet shutdowns planned for Q4 and after mainnet's merge completion.
Kiln testnet is now operational as part of Ethereum's merge testing initiative. The #TestingTheMerge campaign is actively encouraging community participation in testing the transition to proof-of-stake.
Ethereum's merge development continues with minor specification updates and active engineering work. Client diversity remains stagnant with no progress, prompting calls for users to run minority clients to improve network decentralization.
The Stateless Ethereum research initiative has experienced slower development in late 2020 due to pandemic-related disruptions. However, this work on code Merkleization and stateless client technology will become increasingly important as Ethereum approaches the Eth1/Eth2 merge.
Ethereum 2.0 development update #15 reports that the Medalla testnet is running smoothly with continued progress toward Phase 0 launch. The update emphasizes the importance of client diversity and showcases end-to-end testing for The Merge (eth1+eth2 integration).
