A new Ethereum Testnets slate is replacing Holesky, the staging ground once massive now established for closing after two years of service.
The mess will occur two weeks after the Fusaka update is finalized at the end of this year, at which time the client and infrastructure equipment will stop providing support.
Fusaka is configured to make Ethereum’s rollups more cheaper and faster extending “data storage work” more uniform among validators.
Holesky was launched in 2023 to test stress, the testing machinery of Ethereum stagnation at scale. It quickly became the largest public, providing thousands of validators with a platform to update updates before being implemented in the main one.
The main milestones, such as the updates of Dencun and Pin, which reduced the transaction costs and improved validator efficiency, among other characteristics, were executed first through Holesky.
However, the cracks began to appear as the network aged. Holesky found “leaks of inactivity” after the activation of pein at the beginning of 2025, a term that refers to the off -line validators in large quantities, which created a significant portfolio for those who tried to leave.
The result was the lines of one month that made it not practical to test the life cycle of the complete validator. For developers who need fast feedback loops, Holesky had become more an obstacle than a tool.
That is why Ethereum launched Hoodi in March 2025, a clean leg test network to avoid Holesky’s problems while conducting its role as a reference environment for validator and supplier tests.
Together with Hoodi, Sepolia continues to serve as the main test network for DAPPS (decentralized applications) And intelligent contracts, while Ephemery offers validator cycles of rapid delay every 28 days.
