Zcash NU7 makes blocks 3x faster around November 5. Old nodes will split off
Zcash's NU7 hard fork activates at block 3,543,405, expected around November 5, 2026. It cuts block time from 75 to 25 seconds without changing supply, sends 60% of fees to a reserve and invalidates version 4 transactions. Nodes that do not upgrade split off.
Ethereum roadmap explained: Pectra, Fusaka and why Glamsterdam has no date
Ethereum upgrades through named hard forks. Pectra went live on May 7, 2025, and Fusaka on December 3, 2025. Glamsterdam, the next one, is live on the Sepolia testnet but was pulled from Hoodi in October 2026, and as of November 2, 2026, it has no mainnet date.
Base's next upgrade makes blocks 10 times faster. The code says November 5
Coinbase's layer 2 switched on its Cobalt upgrade on September 30. Next is Denim, which cuts block times from 2 seconds to 200 milliseconds and could break contracts that count time in blocks. Base's code sets November 5, 1:00 p.m. ET, though Base still calls November only a target.
Ethereum pulls Glamsterdam from its last testnet four days out. Is gas pricing the problem?
Client teams removed the October 26 Glamsterdam fork from the Hoodi testnet after security concerns were raised on a core developer call. No new date is set, mainnet users need to do nothing, and the mainnet date now waits on Hoodi.
