Ethereum Developers Discuss Upcoming Testnet and Upgrade Plans

On September 21, 2023, Ethereum‘s All Core Developers Consensus (ACDC) call #118 was held, as detailed in a write-up by Christine Kim from the Galaxy Research Team. The bi-weekly ACDC calls, chaired by Ethereum Foundation Researcher Danny Ryan, are pivotal for Ethereum developers to discuss and synchronize changes to Ethereum’s consensus layer (CL). The recent call, which spanned roughly 30 minutes, was predominantly centered around the preparations for the forthcoming Devnet-9.

Key Takeaways from the ACDC Call #118

Devnet-9 Preparations: Devnet-9 is slated to be the second testnet that integrates the complete set of code modifications for the Cancun/Deneb (often termed as Dencun) upgrade. While earlier testnets were centered on Ethereum Improvement Proposal (EIP) 4844, Devnet-9 will mark the activation of EIP 7514 and 7516. Parithosh Jayanthi, a DevOps Engineer at the Ethereum Foundation, revealed intentions to roll out Devnet-9 on September 27, 2023.

Client Readiness: Various Execution Layer (EL) and CL client teams, including Lodestar, EthereumJS, Lighthouse, and Geth, have signaled their preparedness for the Devnet-9 launch. On the other hand, representatives from Besu and Nethermind are in the midst of conducting Hive tests on their Devnet-9 versions. Jayanthi underscored that the launch of Devnet-9 could proceed even if all clients aren’t ready, noting the possibility of adding clients post-launch.

Dencun-related Tests: Ryan identified that certain Dencun-associated tests were malfunctioning. A corrective measure has since been implemented to the “consensus-spec-tests” code repository.

EIP 4788 Deployment: EIP 4788 is set to be deployed as a conventional smart contract, necessitating a contract address for client implementations to activate the code alteration. The definitive contract address for EIP 4788 remains to be determined.

Trusted Setup for EIP 4844: The validation of blobs on Ethereum hinges on a unique value generated through a multi-party ceremony. This ceremony for EIP 4844 transpired from January to August 2023, amassing over 140,000 contributions.

Cancun/Deneb Timing: Tim Beiko, chair of the ACDE calls, expressed reservations about the Dencun testing timeline after Devnet-9. If Dencun isn’t introduced on a public testnet before the November 2023 Devconnect conference, the mainnet activation might be deferred to the subsequent year.

Testnet Launch Sequence: Beiko had earlier suggested a launch sequence for Dencun on the Holesky, Goerli, and Sepolia testnets. However, Jayanthi proposed initiating Dencun on Goerli prior to Holesky, considering Goerli’s looming deprecation.

In summation, the Ethereum developer community is in full swing preparing for Devnet-9 and the Dencun upgrade. The insights from the ACDC call, as reported by Christine Kim, underscore the collective endeavors to ensure Ethereum’s seamless progression.

Ethereum Testnet Successfully Upgrades for Upcoming Shanghai Hard Fork

The Ethereum community is eagerly awaiting the upcoming Shanghai hard fork, which is expected to take place on the mainnet in March. In preparation for this event, the Ethereum blockchain’s Sepolia testnet underwent a successful upgrade on February 28th. The upgrade, dubbed “Shapella”, was designed to simulate the upcoming fork and test its functionality.

One of the most significant changes in the Shapella upgrade is the ability for validators to withdraw their staked Ether (stETH) from the Beacon Chain back to the execution layer. Previously, validators needed to stake a minimum of 32 ETH to validate on the Ethereum blockchain. However, with this upgrade, validators will now be able to withdraw rewards in excess of 32 ETH and continue validating. Those who wish to fully withdraw their staked ETH can take all 32 ETH plus rewards and cease validating.

The successful implementation of the Shapella upgrade on the Sepolia testnet is an encouraging sign for the Ethereum community, as it indicates that the upcoming Shanghai hard fork will likely proceed smoothly on the mainnet. However, before the hard fork can go live on the mainnet, it must first be released on the Ethereum Goerli testnet.

The Goerli testnet is an important testing ground for Ethereum upgrades, as it allows developers to test new features and upgrades in a sandboxed environment before deploying them on the mainnet. The release of the Shapella upgrade on the Goerli testnet is expected to commence in March, giving developers ample time to test the upgrade and ensure its compatibility with the Ethereum ecosystem.

Overall, the successful upgrade of the Sepolia testnet for the upcoming Shanghai hard fork is a promising development for the Ethereum community. With this upgrade, validators will have more flexibility in managing their staked ETH, which will ultimately lead to a more efficient and secure network. As the Ethereum ecosystem continues to evolve and grow, the community can look forward to more exciting upgrades and developments in the future.

Ethereum’s ‘London’ hardfork set to go live on testnets starting June 24th

The hotly anticipated “London” Ethereum hardfork now has a set block height for three Ethereum testnets — a key penultimate step towards a full mainnet launch.

In a blog post on the Ethereum Foundation’s website, Ethereum core developer Tim Beiko wrote that the Ropsten, Goerli, and Rinkeby testnets now have set block heights at which London will go live, with Ropsten expected to be the first at block 10499401, or sometime on June 24th. Goerli is expected to be next on June 30th, and Rinkeby on July 7th.

A release schedule for the all-important mainnet upgrade is still being determined, however.

“As of now, only the testnets (Ropsten, Goerli, Rinkeby) have been scheduled for London. Once the upgrade has successfully been activated on these networks, a block will be set for the Ethereum mainnet and be communicated on this blog and in other venues,” Beiko wrote.

The London hard fork upgrade includes five Ethereum Improvement Proposal (EIP) upgrades, but the star of the show is EIP-1559. An overhaul of Ethereum’s existing fee structure, EIP-1559 is expected to reduce gas costs for users significantly. It may also cut into miner revenues by upwards of 50%, however, which has led to some grublings about a “miner revolt” which has largely failed to materialize.

The upgrade is considered to be one of many bullish catalysts on the horizon for Ethereum, not least of which is the ETH 2.0 upgrade. ETH 2.0 will transition the network to a more scalable proof-of-stake consensus mechanism, which will significantly decrease the energy consumption of validation blocks.

The blog post noted that such significant system upgrades to a decentralized system is a feat of coordination.

“The decentralized nature of blockchain systems makes a network upgrade more difficult. Network upgrades in a blockchain require cooperation and communication with the community, as well as with the developers of the various Ethereum clients in order for the transition to go smoothly.”
