A Bitcoin fork designed to combat network "spam" has ground nearly to a standstill after producing only two blocks, undermined by a lack of mining support that has left the breakaway chain barely functional.
A Fork That Failed to Launch
The anti-spam chain split from the main Bitcoin network but attracted only a sliver of the total mining power behind it. With just 2.53% of hashrate committed to the new chain, the fork struggled to sustain the steady block production that a healthy blockchain requires.
The consequences were immediate and severe. Instead of the roughly 10-minute intervals that Bitcoin targets between blocks, the fork's blocks arrived hours apart. After mining only two blocks, the chain effectively stalled, unable to keep pace with the rhythm that keeps a network alive.
A blockchain without miners is little more than a stalled engine, and this fork ran out of fuel almost instantly.
Difficulty Trap Leaves It Stranded
The core problem lies in Bitcoin's difficulty adjustment mechanism. Difficulty recalibrates only after a set number of blocks are mined, meaning the fork inherited the main network's high difficulty level but lacked the computing power to satisfy it. With so little hashrate, the chain faces an estimated 350 days before it can reach its next difficulty adjustment.
That delay creates a vicious cycle. The high difficulty deters miners from joining, and without more miners, the chain cannot mine enough blocks to lower the difficulty. The result is a network trapped in near-paralysis while the main Bitcoin blockchain continues to operate normally.
Key takeaways from the failed fork:
- The chain attracted only 2.53% of mining support
- Blocks were produced hours apart instead of every 10 minutes
- Roughly 350 days remain before the next difficulty adjustment
- The main Bitcoin network was unaffected and pressed ahead
The episode underscores a longstanding reality of Bitcoin forks: without meaningful hashrate behind them, breakaway chains often collapse quickly, regardless of the technical or ideological goals that inspired them.
