Bitcoin's BIP-110 Soft Fork Faces Critical Test as Signaling Period Begins

 

Bitcoin BIP-110 soft fork signaling period showing nodes, miners, key block heights and potential chain split risk

Aug 8, 2026 – Bitcoin is approaching a rare governance test this weekend as the controversial BIP-110 soft fork enters its mandatory signaling period on August 9, despite receiving support from only a small minority of miners.

The proposal, which would temporarily restrict certain transaction types including large data pushes and oversized scripts, is scheduled to enter mandatory signaling at block height 961,632, with lock-in expected at block 963,648 and activation at block 965,664 in early September.

The unusual situation has sparked debate over Bitcoin governance and could potentially create chain splits if enforcement begins without sufficient support.


What BIP-110 Would Do

Bitcoin Improvement Proposal 110 is designed to make inscription techniques used by Ordinals and Runes impractical by imposing temporary restrictions on non-payment data stored on the Bitcoin blockchain.

The proposal would:

  • Restrict large data pushes and oversized output scripts
  • Limit undefined witness versions and Taproot annex features
  • Enforce restrictions for approximately one year (52,416 blocks)
  • Exempt UTXOs created prior to activation to maintain compatibility with standard monetary use

Supporters argue these measures would prevent non-financial data from consuming block space and undermining Bitcoin's purpose as digital money.


The Governance Dilemma: Miners vs. Nodes

What makes BIP-110 unusual is that it's a user-activated soft fork designed to enforce new rules regardless of miner support. Proponents argue that miners do not govern Bitcoin — they merely produce blocks, while nodes decide whether those blocks comply with rules.

"Bitcoiners are about to show the world, once again, what happens when the plebs stand up against large, corrupt institutions who are telling us Bitcoin isn't money and our nodes belong to them." – Dathon Ohm, pseudonymous author of BIP-110

Under this philosophy, nodes running BIP-110 software will begin rejecting blocks that fail to signal compliance starting August 9, even if those blocks are accepted by the wider network.

If some miners continue producing BIP-110-compliant blocks while the rest mine as usual, two chains could emerge. However, the BIP-110 branch would likely have only a fraction of Bitcoin's hash rate support at the outset, raising doubts about whether it can survive.

Critics point to the lack of miner support as evidence that BIP-110 is effectively dead before it begins. But its supporters reject that premise, drawing inspiration from the successful user-activated activation of SegWit in 2017.


Market Impact and Exchange Precautions

Exchanges and custodians may increase confirmation requirements or temporarily pause deposits and withdrawals if chain instability develops.

Miners have been advised to either pause operations or mine on the expected dominant chain, while exchanges and custodians should monitor both chains to mitigate double-spending risks.

The broader market has shown minimal reaction to the impending fork, with Bitcoin trading relatively stable near $64,000-$65,000 levels. However, increased volatility could emerge if the situation escalates.


What This Means for Crypto Markets

BIP-110 represents more than just a technical upgrade — it's a test of Bitcoin's governance model and the balance of power between miners, nodes, and users.

Key takeaways for traders:

  • Chain split risk: If BIP-110 nodes begin rejecting non-compliant blocks, the network could temporarily split, with implications for transactions and exchange operations
  • Exchange disruption: Some exchanges may increase confirmation requirements or pause deposits and withdrawals around key activation dates
  • Market uncertainty: Any chain instability typically creates short-term volatility in Bitcoin and broader crypto markets
  • Long-term governance precedent: The outcome could influence how future Bitcoin upgrades are approached

The Broader Context: A Big Week for Crypto

August 9 also marks two other significant crypto events:

1. Cardano ETF Milestone

CME Group's regulated ADA futures complete six months of trading on August 9, potentially opening a faster SEC review path for Grayscale's pending spot Cardano ETF. The milestone could satisfy one of the key eligibility criteria, though ADA's previous SEC designation as a potential security remains a risk factor.

2. Major Token Unlocks

Over **$838 million** worth of tokens are scheduled to unlock in August, with **ADI** unlocking approximately $49 million on August 9 and MOVE unlocking about $1.33 million on the same day.

The most significant unlock this month is RAIN with $641.4 million scheduled for August 10, representing approximately 7.24% of its market capitalization.


What to Watch

The Bitcoin community will be closely monitoring whether BIP-110 nodes begin enforcing the new rules and whether any mining pools shift their signaling. The market's reaction to any chain instability could create trading opportunities — and risks.

For now, Bitcoin's governance experiment continues to unfold, testing the principle that ultimately, nodes — not miners — determine Bitcoin's rules.
