Bitcoin Holders Face a Hard Fork on September 1 — Here's What Actually Changes
Luke Dashjr has resigned as chairman and chief technology officer of Bitcoin mining pool OCEAN. The Bitcoin hard fork he backs splits from the main chain on Tuesday.
The company also repurchased all of his equity. He now calls the main Bitcoin chain “Spamcoin.” On Tuesday, a Bitcoin hard fork he backs switches to BLAKE2b, a mining algorithm that existing Bitcoin machines cannot run.
Why Dashjr Walked Away From OCEAN
The exit closes a bruising month for the pool. OCEAN’s hashrate fell 96% in August. The pool had routed customer power to a minority chain for about 18 hours. Miners never gave clear consent and demanded leadership changes.
BIP-110, the anti-spam soft fork Dashjr championed, needed 55% miner support. Signaling peaked at 2.53%. Its chain stalled after two blocks, so backers regrouped around a September breakaway coin instead.
Inside Dashjr’s Bitcoin Hard Fork Plan
Dashjr argues that Bitcoin lost decentralized block construction years ago. He says BLAKE2b removes a shortcut called ASICBoost, which hands large miners an efficiency edge. He also says it punishes concentrated mining power.
Critics reject that reading. Adam Back had already called BIP-110 idiocracy in July. Ripple’s former chief technology officer David Schwartz dismissed the network under attack claim as nonsense.
Spamcoin isn't Bitcoin and operates under centralized management, just like the US dollar, but worse.

Spamcoin does not allow miners to build their own template.
DATUM has no purpose on Spamcoin. Claiming it decentralizes anything is false advertising.
He says the legacy chain runs under centralized management and blocks miners from building their own templates. Dashjr now channels that into CONVOY, which he frames as a second run at decentralized mining. OCEAN, meanwhile, keeps operating as a non-custodial pool.
What Happens to BTC on September 1
Bitcoin (BTC) trades near $77,655, down 0.59% on the day. It has still gained 23.3% this month. Hashrate has drifted lower all year as miners leave the network for artificial intelligence contracts. That trend thins the pool of machines any breakaway chain could recruit.
Holders face two practical questions, namely replay risk and which chain their wallet tracks. Dashjr recommends a light wallet over a full node. Both questions already surfaced during the August chain split.
A proof-of-work change mints a separate coin. The market then prices which chain carries value.
Dashjr’s previous fork attempt never cleared 3% support. Tuesday, therefore, tests one question. Either real hashrate follows BLAKE2b, or the split repeats the August stall and freezes within hours.
