Developers at the Ethereum foundation decided on eight Ethereum Improvement Proposals (EIP) to explore for the Shanghai update, the next major upgrade after the Merge and its move to proof-of-stake (PoS) consensus, announced the Ethereum Foundation on Nov. 24.
This is an experimental testnet run in cooperation with EF DevOps which activates a set of selected Shanghai-considered EIPs for early client testing.
One of the main features expected to be in the Shanghai hard fork, Beacon Chain staked Ether (ETH) is set to be unlocked, allowing the assets will be able to be withdrawn with the upgrade, meaning that users with staked Ethereum prior to the Merge will be able to access those tokens, as well as any other rewards. A previous timeline anticipated locked ETH to be accessible 6-12 months after the Merge.
Among the approved proposals is the EIP 4844, which focuses on leveraging proto-danksharding technology, and is expected to boost network throughput and slash transaction fees, a significant improvement for scalability. Other EIPs address the upgrade of Ethereum Virtual Machine (EVM), including EIP 3540, EIP 3670, EIP 4200, EIP 4570 and EIP 5450.
The Shanghai testnet version, dubbed Shandong, went live on Oct. 18, allowing developers to work on implementations such as Ethereum Virtual Machine (EVM) object format, is one of the community’s most-anticipated updates since it separates coding from data, which could be beneficial for on-chain validators.
As previously reported by Cointelegraph, the Merge was the first step in this five-part process, which has since been elaborated upon by a number of Ethereum developers, ecosystem participants and commentators. The key change of the Merge is the drastic reduction in power consumption, which should reduce Ethereum’s energy usage by 99%.
