What an Actual Bitcoin Hard Fork Looks Like: The BLAKE2b Fork Swapped the Mining Algorithm, and 97% of Hashrate Chose Not to Follow

A soft fork only got 2.53% miner support. Swapping the entire mining algorithm didn't move that number either — proof that no matter how radical the fork's technical approach, it can't manufacture consensus the market never had to begin with.
Hiroshi Endo · September 18, 2026
The BLAKE2b fork, led by Bitcoin Knots developer Luke Dashjr, formally split away from the Bitcoin mainchain at Block height 961,632 on August 8, 2026, and completed the actual mining algorithm switch at block 961,640 on August 30 — replacing SHA-256d, the algorithm Bitcoin has run on for years, with BLAKE2b. This event is worth recording not because of whether it succeeded (the new chain currently has almost no exchange support and near-zero trading volume), but because it demonstrates the...

Canonical Bridge
The official bridging channel operated by a Layer 2 or sidechain team itself, where asset security directly inherits the destination chain's own consensus and fraud-proof mechanism, at the cost of a longer withdrawal challenge period.
What is a canonical bridge, and how does it differ from what people commonly call a cross-chain bridge? A canonical bridge is a bridging contract...

51% Attack
A <a href="/en/glossary/consensus-mechanisms/51-percent-attack/">51% Attack</a> occurs when a single entity gains control of more than half of a blockchain's <a href="https://crypto-bible.com/en/glossary/blockchain-fundamentals/block/" target="_blank" rel="noopener">Block</a>-production power (hash power on PoW chains, staked tokens on PoS chains), letting them rewrite recent transaction history and double-spend their own funds — but not steal assets from other people's wallets.
