Ethereum’s [ETH] predominant improve agenda in 2026 has hit a hiccup. The a lot-awaited Glamsterdam improve, initially scheduled to go dwell on the Hoodi testnet on the twenty sixth of October, has been cancelled.
According to safety agency Chain Security, the Hoodi testnet was paused after they recognized safety flaws which have already impacted 13 initiatives and counting.
We already discovered 13 actual-world examples and are in accountable disclosure with the affected initiatives. Please examine your contracts as quickly as potential, because the EF is figuring out what number of contracts are impacted through which method.
The flaw would make it inconceivable to retry cancelled transactions. It would additionally make it simpler for attackers to compromise a wise contract with little gasoline (price paid to make use of a community).
Glamsterdam upgrade seeks to scale Ethereum even additional by growing the block gasoline restrict from 60 million to 200 million and permitting parallel transaction dealing with. Ideally, the improve would make Ethereum excessive-efficiency like newer chains equivalent to Solana and Sui.
The improve had a easy completion within the Sepolia Testnet in early October. This is the primary low-threat setup for builders and validator operators to guage compatibility. The Hoodi Testnet, which has been paused, acts as the ultimate staged atmosphere earlier than pushing the improve to Ethereum mainnet (dwell community).
So the safety flaw was an ideal catch earlier than it reached the mainnet. That mentioned, Solana achieved 85x sooner transaction finality, additional growing its hole with Ethereum.
Ethereum vs. Solana: The hole retains widening
After Solana’s Alpenglow, it’s now 57x sooner than Ethereum and has 275x extra capability. It’s the capability bandwidth that Ethereum is making an attempt to resolve by growing the block gasoline restrict from 60 million to 200 million.
On transaction finality, it takes Ethereum over 12 minutes to finalize irreversible transactions. For Solana, it now takes 150-200 microseconds, translating to three,800x sooner than Ethereum.
Collectively, this has allowed Solana to draw 75x extra utilization, and that’s the hole Ethereum needs to shut. In truth, Solana additionally introduced Alpenglow variations to usher in its publish-quantum plan known as Quantumglow.
Despite the Glamsterdam testnet hiccup, Ethereum is reportedly planning for 4x sooner finality. That would imply bringing finality from over 12 minutes to about 3 minutes. It will nonetheless be slower in comparison with Solana’s 0.15 seconds.
The proposal, also called Decoupled Consensus, seeks to supply a cleaner pathway to publish-quantum signatures and is anticipated in early 2028.
Overall, Ethereum continues to be lagging Solana and must quick-monitor its upgrades because the hole retains widening.
Final Summary
- Ethereum has cancelled the Hoodi testnet activation for Glamderstam improve attributable to safety flaws.
- Ethereum lags behind Solana throughout finality, capability, and extra because the race for prime-efficiency blockchain intensifies.
