Ethereum (ETH) developers are set to launch Hoodi, a new long-lived testnet, on March 17 as they work to resolve ongoing challenges with the highly anticipated Pectra upgrade.

The testnet will primarily focus on validator exit mechanisms, one of the final hurdles before Pectra can move forward. Broader testing will continue on Ethereum’s Sepolia and Holesky testnets.

The Pectra upgrade, which merges features from the Prague and Electra proposals, aims to improve staking operations, enhance the execution and consensus layers, and introduce key optimizations for Ethereum validators.

However, the upgrade has faced repeated delays due to client readiness issues, synchronization bugs, and infrastructure concerns.

According to Ethereum Foundation developer Tim Beiko, Pectra’s mainnet activation will only proceed if Hoodi successfully forks and client teams confirm confidence in the upgrade’s stability.

Even in the best-case scenario, mainnet activation will not happen until at least 30 days after Hoodi forks, setting April 25 as the earliest possible date.

Pectra struggles

Ethereum developers have been working through a series of unexpected challenges with Pectra, including problems with validator exits, network synchronization, and compatibility between client implementations.

The delays stem from issues encountered during testnet deployments. The Holesky testnet, for instance, failed to finalize after the Pectra upgrade, leading to potential mainnet launch delays as developers investigate the problems.

Similarly, the Sepolia testnet experienced misconfigurations, prompting developers to extend the testing period to gather more data before proceeding with the mainnet activation.

Additionally, some client teams have expressed concerns about last-minute changes to the upgrade’s scope, which has complicated the testing process. Ethereum’s modular development structure means that upgrades must be coordinated across multiple teams working on different execution and consensus clients, adding to the complexity.

​The Ethereum community has expressed mixed reactions to the recent delays in the Pectra upgrade. While some members are frustrated by the postponements, others appreciate the developers’ cautious approach to ensuring network stability.​

Despite these setbacks, many community members remain optimistic about Pectra’s potential benefits, including improved staking flexibility and enhanced scalability

Fusaka upgrade

While Pectra remains a priority, Ethereum developers are also progressing with planning for the Fusaka upgrade, which will follow Pectra.

Fusaka will introduce Peer Data Availability Sampling (PeerDAS) to improve data handling by allowing validators to sample data instead of downloading full datasets, reducing bandwidth requirements.

It also implements the Ethereum Virtual Machine Object Format (EOF) to optimize smart contract execution by enabling code-data separation and versioning, lowering costs for developers.

The Ethereum core team has set a March 24 deadline for Ethereum Improvement Proposals (EIPs) to be considered for inclusion. Client teams are expected to share their scope preferences by March 31, with a tentative scope freeze set for April 10.

Ethereum developers remain committed to ensuring a stable and secure network upgrade. However, the multiple delays with Pectra underscore the increasing difficulty of coordinating large-scale changes to Ethereum’s infrastructure as it continues to scale.
