Abstract generation in progress
The key blockchain upgrades in the second half of 2026 will focus on protocol performance, reliability, and institutional-grade infrastructure. The article lists upgrades related to the Ethereum network’s Glamsterdam, Solana Alpenglow, Base Beryl, and Avalanche Octane, as well as Bitcoin covenant proposals such as OP_CAT/CTV and discussions on quantum resistance. Among them, Glamsterdam is expected to go live in the second half of the year, Solana Alpenglow aims to reduce final confirmation time to approximately 100–150 milliseconds, and Base Beryl has shortened the withdrawal final confirmation time from 7 days to 5 days. Bitcoin-related proposals still lack a clear activation path, making a major soft fork less likely within the year. (Cointelegraph)

Avalanche Octane didn't mention specific data, the term "institutional-grade infrastructure" is too vague, waiting for actual testing.

Quantum-resistant discussions are now starting to lay out plans. Conservatives may think it's unnecessary worry, but the cryptography community is indeed anxious.

Solana's confirmation time has been reduced to 100ms, which indeed improves user experience, but the accusation of centralization is probably hard to shake off.

Base withdrawals take 5 days to reach final confirmation—doesn’t really feel like it affects retail investors, but it’s a big headache when it comes to institutions’ fund scheduling.

Glamsterdam is finally coming, this Ethereum performance upgrade has been delayed long enough, just hope it doesn't cause another gas explosion.

How long has OP_CAT been hyped on the Bitcoin side? Without an activation path, it’s just empty promises—probably delayed again in 2026.
