Bitcoin Hard Fork on September 1 Follows OCEAN Hashrate Collapse and Dashjr's Exit
OCEAN's hashrate fell 96% through August after the Bitcoin mining pool routed customer power to a minority chain for roughly 18 hours without clear miner consent, and the turmoil closes with Luke Dashjr's resignation as chairman and chief technology officer one day before a hard fork he backs is set to split from the main Bitcoin chain. OCEAN also repurchased all of Dashjr's equity as part of the separation. The fork switches proof-of-work to BLAKE2b, an algorithm existing Bitcoin mining hardware cannot run, leaving $BTC holders on notice about replay risk and which chain their wallet tracks.
Key takeaways
- OCEAN's hashrate fell 96% through August after the mining pool routed customer power to a minority chain for about 18 hours without clear miner consent.
- Luke Dashjr resigned as OCEAN's chairman and CTO one day before a September 1 hard fork he backs is set to split from the main Bitcoin chain, and OCEAN repurchased all of his equity.
- The hard fork switches proof-of-work to BLAKE2b, an algorithm existing Bitcoin mining hardware cannot run, creating replay risk for $BTC holders.
- Dashjr's earlier BIP-110 anti-spam soft fork needed 55% miner support but peaked at 2.53% signaling and stalled after two blocks.
- Bitcoin trades near $77,655, down 0.59% on the session and up 23.3% through August.

The operational collapse at OCEAN
Dashjr now calls the main Bitcoin chain "Spamcoin." His earlier campaign, BIP-110, was an anti-spam soft fork that needed 55% miner support to advance. Signaling peaked at 2.53%, the chain stalled after two blocks, and backers regrouped around the September breakaway instead.
The capacity picture heading into Tuesday is already thin. Network hashrate has drifted lower all year as miners redirect machines to artificial intelligence contracts, narrowing the pool of hardware any breakaway chain could recruit. BLAKE2b's incompatibility with current rigs narrows it further. Dashjr argues the algorithm removes ASICBoost, a shortcut he says hands large miners an efficiency edge and punishes concentrated mining power. Adam Back called BIP-110 "idiocracy" in July. Ripple's former chief technology officer David Schwartz dismissed the claim that the network is under attack as nonsense.
The setup for $BTC
Bitcoin trades near $77,655, down 0.59% on the session and up 23.3% through August. A proof-of-work change mints a separate coin, and the market then prices which chain carries value. Dashjr's previous fork attempt never cleared 3% support, so Tuesday tests the same question one more time: whether real hashrate follows BLAKE2b or the split freezes within hours the way the August chain did. Dashjr recommends a light wallet over a full node for anyone managing replay risk from the split.
What to watch: how much hashrate commits to BLAKE2b on September 1, and whether CONVOY, Dashjr's new project framed as a second attempt at decentralized mining, draws any of the operator base OCEAN just shed. OCEAN keeps running as a non-custodial pool.
