A breakaway Bitcoin chain launched over the weekend has fallen dramatically behind the main network, mining just two blocks since it split off on Saturday while Bitcoin itself produced more than 300 in the same period.
A Fork That Can't Keep Up
The new chain, born from the BIP-110 fork, is struggling to attract the mining power needed to function as a viable network. With only two blocks produced since the split, the fork has effectively stalled, unable to match the pace of the original Bitcoin blockchain that continues to churn out blocks roughly every ten minutes.
The imbalance illustrates a core challenge for any breakaway chain: without a substantial share of hashrate, block production grinds to a crawl. When miners overwhelmingly favor the dominant chain, the minority fork is left waiting far longer between blocks, making it slow and unattractive to users.
Two blocks in the time it took Bitcoin to mine more than three hundred is a stark measure of a fork that has failed to gain traction.
The Long Road to Recovery
The root of the problem lies in Bitcoin's difficulty adjustment mechanism, which recalibrates roughly every 2,016 blocks to keep block times near the ten-minute target. Because the fork inherited a difficulty level calibrated for the full network's hashrate, its diminished mining power means it will take an extraordinarily long time to reach the next adjustment.
By some estimates, the chain could take around six years to naturally correct itself and bring block times back to normal, assuming its current sluggish pace holds. That timeline underscores how difficult it is for a low-hashrate fork to become functional without a mechanism to reset difficulty more quickly.
Key takeaways from the situation:
- The BIP-110 chain produced only two blocks after splitting Saturday.
- Bitcoin generated over 300 blocks in the same window.
- The fork may need about six years to self-correct via difficulty adjustment.
For now, the breakaway chain remains largely inert, a reminder that consensus rules and miner support ultimately determine whether a fork survives or fades into irrelevance.
