Bitcoin's BIP-110 fork stalled after two blocks — a lesson in how forks live or die

A proposed rule change called BIP-110 split a new chain away from Bitcoin last Saturday, but the breakaway chain has produced only two blocks and then stalled, while the main Bitcoin network has added more than 300 in the same stretch — a real-time lesson in why most forks fail.

A fork happens when part of the network starts following different rules. BIP-110 wanted to stop people storing pictures, text and other non-payment data in Bitcoin transactions for a year. Changing Bitcoin's rules normally needs miners to agree, and BIP-110 asked for 55% support over two weeks but reached only about 2.6%. It had a fallback built in, though: at a set block, computers running its software began rejecting every block that did not carry its mark, and since almost none did, they split off onto a chain of their own.

The breakaway chain then froze, and the reason is the heart of how Bitcoin stays alive. Both chains inherited the same mining difficulty when they parted, but the new coin has no market, no exchange listing and no buyers — so miners have no reason to spend electricity on it. With almost no mining power behind it, the fork now sits 326 blocks behind Bitcoin.

It also cannot rescue itself quickly. Bitcoin recalculates its mining difficulty every 2,016 blocks — about two weeks at the normal pace of one block every ten minutes — and only then can a struggling chain make mining easier. Because the fork is barely producing blocks, that adjustment is now estimated to be about 6.3 years away, up from 350 days just a day earlier. Bitcoin's own next adjustment is due in under two weeks. The developer most involved in BIP-110 was also removed as a Bitcoin Improvement Proposal editor amid the dispute.

The takeaway for a beginner is that Bitcoin's rules only really change when miners and the wider economy agree to back them; a split without that backing is just a stalled copy, not a new Bitcoin. Some analysts caution it is too early to call the experiment fully dead, but a forked coin with no market behind it is not a windfall. This is information, not advice.
