The Ropsten testnet – Ethereum’s longest-running testnet – implemented the long-awaited “merge” with the Beacon chain on Wednesday. The upgrade brings Ethereum one step closer to its long-awaited turnaround and proof of stake consensus mechanism.
- Ropsten allows development and testing before changes are implemented on the Ethereum mainnet. “The Merge” will be the most significant upgrade ever made by Ethereum.
- The testnet is similar to Ethereum’s mainnet, but does not risk any actual funds.
- Ethereum Core Developer Terence Tsao First announced That the configuration of Ropsten’s beacon series was merged on 18 May. Client releases began on May 30th, with the full testnet transition slated for today.
- Bellatrix upgrade It then successfully launched on 2 June, as the final upgrade was necessary before the full Ropsten merge.
- As of 16:09 UST on Wednesday, Ropsten’s Proof of Work chain reached a total difficulty of above 50 quadrillion, and stopped importing blocks on that chain segment.
- “Terminal Total Difficulty” refers to a pre-determined difficulty value at which a merge is required.
- After that, stake validators began to build blocks on a continuous chain built from prior proof of work history.
- Proof of Stake is expected to make Ethereum a more energy-efficient blockchain, while also significantly reducing transaction fees. At the moment, the high transaction fees have contributed to the failure of over a million Ethereum transactions every month.
