Ethereum’s tenth "shadow fork" went into effect Tuesday, 26 hours earlier than expected, as the network continues to run tests ahead of the anticipated shift from using the energy-intensive proof-of-work protocol to proof-of-stake.
In preparation, Ethereum has been undergoing a series of test, or shadow, forks, which copy data from the main network (mainnet) to a test environment network (testnet).
- The shadow fork brings the project one step closer to Ethereum's mainnet upgrade in September. The third and final testnet merge, Goerli, is expected to happen Aug. 10.
- Ethereum DevOps Engineer Parithosh Jayanthi told CoinDesk that this shadow fork will test releases that approximate the releases that will be used in the Goerli merge.
- As for why it happened earlier than expected, Jayanthi said there was a clear change in the hashrate, or computational power, that could have sped up the process.
- This will not be the last mainnet shadow fork, and Ethereum will continue to run mainnet shadow forks until the Merge.
- No significant glitches were reported.
