Ropsten will be Ethereum’s first public test network to transition from доказ за работа (PoW) до a доказ за удел (PoS) consensus mechanism as part of the blockchain’s “Се логирате” event, expected Август оваа година.
Ethereum core developer Tim Beiko shared the news on Twitter last night: “Ethereum’s longest-lived PoW testnet is moving to Proof of Stake! A new beacon chain has been launched today, and The Merge is expected around June 8th on the network.”
Beiko called the news a “first dress rehearsal” for miners.
Beiko then fired off a nine-tweet thread covering the technical details of the Merge for miners. He informed developers that “basically nothing should change” post-Merge.
Ropsten’s newly-launched beacon chain will undergo a “Bellatrix” upgrade to be Merge-compatible around јуни 2. A few days after this, a value known as the Terminal Total Difficulty (TTD) will be chosen by miners to trigger the transition. Miners will then need to configure their nodes with this value.
Според блог пост by Ethereum: “After the Ropsten transition, two more testnets (Goerli and Sepolia) will be transitioned to proof-of-stake before focus shifts to mainnet.”
The Ethereum Foundation also upped its bug bounty payouts recently to help facilitate a problem-free transition.
Ethereum, Testnets, and the Merge
Launched in 2016, Ropsten is Ethereum’s longest-running PoW test network (testnet). Testnets are identical in every key aspect to the “mainnet,” and are used by developers to test smart contracts and decentralized applications (dApps).
Ropsten uses a valueless form of Ethereum to execute transactions and test the coding environment. Changes made to the testnet do not affect Ethereum’s mainnet. This consequence-free environment gives developers key insights into any potential problems that might arise from their coding.
Порано познат како 2.0, Ethereum’s long-anticipated mega upgrade will transition the network from a consumptive PoW consensus algorithm à la Bitcoin – where transactions are validated by miners with a lot of computing power – to PoS, in which miners who put up the most collateral validate the most transactions.
Ethereum claims this will cut the blockchain’s energy consumption by up to 99.5%.
"Спојување" refers to the point when Ethereum’s mainnet will converge with the PoS-based Ланец на светилници. After that, Ethereum 2.0 (which was recently ребрендиран до „Слој на консензус“) ќе биде отворен и ќе работи.
