Bitcoin's Bizarre Offshoot Stalled for Six Years

A breakaway Bitcoin chain has produced exactly two blocks in four days while the main network has processed over 300. Its self-correction mechanism is now an estimated six years away, and every idle hour pushes that date further into the future.

According to CoinDesk, this is the story of the BIP-110 fork. It launched with a spectacular lack of planning and gives a masterclass in how a blockchain fails. The split occurred at block 961,632 last Saturday, triggered by software designed to ban non-payment data like images from Bitcoin transactions. When it failed to win miner support, the BIP-110 code activated a mandatory split. It immediately stalled.

"I think it is still too early to draw any firm conclusions from the initial block production," said Himanshu Sahay, co-founder of Arch. "I would be cautious about describing it as a failure at this stage."

If miners abandon a fork, the story is usually over. This time, the failure is unfolding in slow motion. The numbers tell it best.

How a disorganized Bitcoin split devoured its own progress

A fork is not just copying software. It is an attempt to start a new, credible economic network. The BIP-110 fork demonstrates what happens when you only execute step one.

The proposal sought to enforce a temporary ban on data storage via Bitcoin transactions. Changing Bitcoin’s rules requires miner consensus, signaled by marking blocks. BIP-110 needed 55% of blocks over two weeks to signal support. At its peak, it got 2.6%.

Instead of accepting defeat, the proposal’s code contained a trapdoor. At the designated block height, 961,632, any computer running BIP-110 software began rejecting all blocks that did not carry the specific version bit for the proposal. Since almost no miners were signaling for it, those nodes instantly forked off onto a chain only they recognized. Two blocks were mined on that new chain by a pseudonymous group called Roughnecks. Then, it ground to a halt. The rest of the Bitcoin network, representing what Michael Saylor estimated as 99.85% of the network's hashpower, raced ahead.

The math from the outset was broken. The two chains diverged not as competing visions, but as one functional network and one ghost chain.

The broken thermostat crippling this Bitcoin offshoot

The core technical failure is Bitcoin’s difficulty adjustment. This is the network's thermostat. It ensures blocks are produced roughly every ten minutes by tuning the mathematical puzzle miners must solve. Every 2,016 blocks, the network recalculates. If blocks came too fast, it makes the puzzle harder. Too slow, and it eases up.

When the BIP-110 chain split, it inherited Bitcoin’s current difficulty level, which had just adjusted to a staggering 127.48 trillion. It also inherited virtually none of the hashpower needed to solve puzzles of that magnitude.

Mining the BIP-110 chain now costs exactly the same in electricity and hardware as mining a real Bitcoin block. The reward, however, is a coin with no market value, no exchange listings, and no buyers. There is zero economic incentive for any rational miner to point hardware at it. With only a tiny fraction of hashpower, blocks that should take ten minutes could take weeks or months.

Worse, the fork is stuck in this state. It cannot lower its own difficulty until it completes a full 2,016-block period. With only two blocks mined, it needs 2,014 more. At its current pace, essentially zero, a live monitor now estimates the next adjustment is 6.3 years away, a figure that increases with every minute no new block is found. This isn't a slow chain. It is a chain in a cryptographic death spiral.

A case study in what not to do when forking a blockchain

Contrast this with a successful fork like Bitcoin Cash in 2017. That split involved a coordinated migration of miners, developers, exchanges, and economic value. It planned for the separation, including a "Difficulty Adjustment Algorithm" (DAA) designed to quickly adapt to the new chain's lower hashpower. It was a contentious but functional network launch.

The BIP-110 fork had no such coordination. It was a software trigger pulled without securing the necessary economic and mining support. This outcome validates a core Bitcoin principle: software consensus is meaningless without Nakamoto Consensus, the proof-of-work secured by the majority of global hashpower.

The lesson is blunt. A viable blockchain requires four pillars working in concert:

• Software (the code change)
• Miners (the hashpower securing it)
• Economy (the value and liquidity of its coin)
• People (developers, users, businesses)

This fork attempted to bootstrap a new chain with only the first pillar. It is a pristine, real-time example of why that is impossible. The public failure here, as covered in our analysis of previous miner discontent over BIP-110 in Bitcoin Miner Defies Own Pool's Vote on BIP-110, shows how deeply divided the ecosystem was on this proposal from the start.

What the death spiral of BIP-110 means for Bitcoin's future forks

This public spectacle, while a failure for BIP-110 proponents, is a powerful stress test that reinforces the security of the main Bitcoin chain. It demonstrates the immense, almost immovable, inertia of the established network. A tiny group of developers and a sliver of hashpower cannot credibly threaten or split the chain without overwhelming coordinated support.

For investors and the broader market, this event serves as a filter. It will make participants intensely skeptical of any future "technical" forks that lack explicit, supermajority miner backing demonstrated over time. The market's reaction has been clear: focus remains on the dominant chain, as evidenced by the continued accumulation by large holders, a trend we explored in Bitcoin Whales Quietly Hoard $1.5 Billion Amid Retail Panic.

The forward-looking implication is not about this dead chain. It is about the durability of Bitcoin itself. The six-year timeline is not a countdown to revival; it is a countdown to obscurity. Each passing day the fork remains frozen makes a revival more computationally and economically improbable. The real story is how this rapid, public collapse highlights exactly what makes Bitcoin so stubbornly resistant to fracture: its deeply intertwined alignment of security, economics, and decentralized social consensus. Any fork that fails to replicate that alignment isn't just slow. It is stillborn.

Why This Changes Everything

• The extreme lag (300 blocks behind) shows this fork has effectively failed as a functional blockchain network.
• A six-year delay for difficulty adjustment means the network cannot self-correct, rendering it economically unviable.
• This demonstrates that without significant miner consensus, even well-intentioned protocol splits risk collapsing entirely.
