Ethereum’s [ETH] predominant improve agenda in 2026 has hit a hiccup. The a lot-awaited Glamsterdam improve, initially scheduled to go stay 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 tasks and counting.
We already discovered 13 actual-world examples and are in accountable disclosure with the affected tasks. Please examine your contracts as quickly as potential, because the EF is figuring out what number of contracts are impacted wherein manner.
The flaw would make it unimaginable to retry cancelled transactions. It would additionally make it simpler for attackers to compromise a wise contract with little gasoline (charge 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 comparable to Solana and Sui.
The improve had a clean completion within the Sepolia Testnet in early October. This is the primary low-danger setup for builders and validator operators to judge compatibility. The Hoodi Testnet, which has been paused, acts as the ultimate staged surroundings earlier than pushing the improve to Ethereum mainnet (stay community).
So the safety flaw was an important catch earlier than it reached the mainnet. That stated, Solana achieved 85x quicker transaction finality, additional growing its hole with Ethereum.
Ethereum vs. Solana: The hole retains widening
After Solana’s Alpenglow, it’s now 57x quicker 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 quicker than Ethereum.
Collectively, this has allowed Solana to draw 75x extra utilization, and that’s the hole Ethereum desires 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 quicker 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 referred to as Decoupled Consensus, seeks to supply a cleaner pathway to publish-quantum signatures and is predicted in early 2028.
Overall, Ethereum remains to be lagging Solana and must quick-observe its upgrades because the hole retains widening.
Final Summary
- Ethereum has cancelled the Hoodi testnet activation for Glamderstam improve because of safety flaws.
- Ethereum lags behind Solana throughout finality, capability, and extra because the race for top-efficiency blockchain intensifies.
