Ethereum launches testnet for Shanghai upgrade: Here’s what is next
Staked ETH withdrawal and lower gas fees are some of the developments expected with the next critical improvements for the Ethereum network, the Shanghai upgrade. The testnet version, dubbed Shandong, is now live. Developers can now begin working on the implementations; a process expected to continue until September 2023.
This is the first major update since Ethereum's consensus switched to Proof-of-Stake (PoS) in September after the Mainnet and Beacon Chains merged.
Moreover, the coming upgrade introduces an elemental change to Ethereum Virtual Machine (EVM), the technology that powers the network smart contracts. EIP-3540, or 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. Galen Moore, content lead at Axelar, told Cointelegraph about the proposal:
Another expected proposal is EIP-4895, which will allow staked ETH and earned rewards withdrawals via the Beacon Chain. In order to ensure network stability, validators with staked ETH currently cannot withdraw funds directly.

Among the proposals under consideration, the upgrade will also introduce changes to layer-2 protocols, reducing gas prices by equalizing block sizes and increasing calldata efficiency in the network. Moore also noted:
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, reducing Ethereum’s energy usage by 99%.
