Fact Checked by Coinsbeat Editorial Team | Expert Reviewed by ThemiyaJameson Lopp posted a chart. The Bitcoin community promptly lost its mind. And honestly? The chart deserved the reaction.
The chart, captioned “Spot the Sybil Attack,” shows BIP-110 signaling nodes spiking hard while Bitcoin Knots nodes whipsawed around like a broken compass. That’s not organic adoption. That’s a coordinated push, and anyone who’s watched Bitcoin governance fights for more than five minutes knows exactly what this pattern smells like.
What BIP-110 Actually Is (And Why Core 30 Lit the Fuse)
Let’s be real about the timeline here. Bitcoin Core 30.0 dropped on October 10, 2025, and it raised the default -datacarriersize to 100,000 bytes. Multiple OP_RETURN outputs? Now fine for relay and mining. For the anti-spam crowd, that was a declaration of war.
BIP-110 is the counter-punch. Filed by Dathon Ohm (with Luke-Jr credited for original drafting), it’s labeled a “Reduced Data Temporary Softfork.” The proposal would:
- Cap OP_RETURN outputs at 83 bytes
- Limit new output scripts to 34 bytes
- Restrict data pushes and witness elements to 256 bytes
- Cap Taproot control blocks at 257 bytes
- Invalidate OP_SUCCESS opcodes and executed OP_IF / OP_NOTIF in Tapscript during deployment
That last cluster of restrictions isn’t minor housekeeping. It reaches deep into Taproot’s architecture. BitVM-style large Taptrees? Dead in the water during deployment. Advanced Miniscript wallets? Need updates. There’s even a narrow window where funds could theoretically get frozen. The proposal acknowledges this and calls it “extremely unlikely.” Comforting.
The activation design makes the whole thing more combustible. BIP-110 uses a modified BIP9 mechanism with a 55% miner signaling threshold and a target activation height around September 1, 2026. That means 45% of hashrate could be producing blocks the activated chain rejects. A chain split isn’t a hypothetical here. It’s baked into the math.
The Node Count Problem Is Older Than This Fight
Here’s the thing about public reachable node counts. They have never, not once, been a reliable measure of economic consensus in Bitcoin. Lopp isn’t inventing this argument. He’s repeating it because people keep forgetting it.
Bitcoin Unlimited tried this in 2016. SegWit2x tried it in 2017. Both waved node counts like flags of legitimacy. Both got crushed because miners, exchanges, and wallet operators, the people who actually move economic weight, didn’t follow. The nodes were theater. The economy spoke differently.
The current data situation makes the ambiguity worse, not better. Coin Dance counts 23,189 public Bitcoin nodes, with 5,193 running Knots after correcting for duplicates and non-listening nodes. Smart Wicked Bitcoin (the platform Lopp used) shows 11,997 Knots nodes and 10,361 BIP-110 signaling nodes. Same network. Wildly different pictures. The difference is methodology, not reality.
Lopp’s specific accusation is architectural. Running Tor nodes is practically free. Spinning up cloud instances costs almost nothing. If one actor, or a small coordinated group, wanted to manufacture the appearance of consensus, the cost would be laughably low. That’s the Sybil attack he’s pointing at.
The Distribution Campaign That Made This Easier
Look, the surge didn’t happen in a vacuum. There’s a concrete infrastructure story behind it. On February 6, myNode released version 0.3.41 with a “Bitcoin Knots + BIP110 Custom Bitcoin Version” install option. A RaspiBlitz pull request on February 19 updated its Knots installer for a BIP-110 build. The official BIP-110 site lists simplified install paths across Start9, Umbrel, myNode, Parmanode, and Docker, and it explicitly encourages users to run signaling nodes to demonstrate support.
That last part is important. The BIP-110 site is openly running a node recruitment drive. That’s not a grassroots movement. That’s a campaign. Genuine adoption and manufactured optics are both in the mix, and nobody can cleanly separate them from the outside.
What This Actually Means for Bitcoin’s Governance (The Ugly Part)
Forget the technical specs for a moment. The deeper issue is what this fight reveals about how Bitcoin gets changed, or doesn’t.
Core 30 changed the defaults first. No contentious fork, no dramatic showdown. Just a policy shift at the node relay level that the anti-spam faction found completely unacceptable. BIP-110 is the response, and its proponents are trying to win a governance argument by flooding the visible signal layer with nodes. Whether those nodes represent real economic actors is the entire question.
Lopp’s framing is precise: economic weight is what actually determines consensus. Miners who control hashrate. Exchanges that process volume. Wallet providers serving millions of users. None of that shows up in a node count chart. A soft fork that can’t bring those actors along doesn’t activate. It just creates noise, and potentially a chain split at 55%, before failing.
Bitcoin has been in this exact room before. The difference this cycle is that Core changed defaults before the governance fight concluded, and BIP-110’s proponents are running a far more organized distribution effort than previous dissenters managed. That makes the situation louder. It doesn’t make it more resolved.
The Taproot Collateral Damage Nobody Wants to Talk About
If BIP-110 somehow activates, the Taproot implications aren’t trivial. Developers building on advanced Taproot constructions would be working in a temporarily hostile environment. OP_SUCCESS hooks are a core part of Taproot’s upgrade path. Restricting them during deployment isn’t a minor inconvenience. It’s a constraint on Bitcoin’s ability to evolve during a window that could last months.
Supporters frame it as a temporary cost worth paying to restore Bitcoin’s monetary focus. Critics point out that temporary restrictions in consensus systems have a habit of becoming permanent because the political will to unwind them evaporates once the immediate fight is over.
The Risk Factor Every Bitcoin Holder Should Internalize
Honestly, if you hold BTC and you’re not tracking this, you should be. Here’s the concrete risk breakdown:
- Chain split risk: A 55% activation threshold is genuinely dangerous. It’s not a supermajority. It leaves a substantial minority potentially running incompatible consensus rules. Exchanges would be forced to choose sides or halt withdrawals. Price would react violently.
- Developer friction: Any ambiguity about Bitcoin’s data policy delays serious application development. Projects building on Taproot features will slow down or route around Bitcoin entirely.
- Governance erosion: If node count manipulation becomes an accepted tactic, every future Bitcoin governance fight gets dirtier. The signal layer becomes noise permanently.
- Activation failure scenario: If BIP-110 fails to reach 55% and the September 2026 deadline passes, Bitcoin spends six to nine months in governance theater while the actual OP_RETURN policy question stays unresolved. That’s not a neutral outcome. That’s wasted momentum and residual community fracture.
Pro-tip: Watch miner signaling, not node counts. When major mining pools start publicly declaring positions on BIP-110, that’s the real signal. Node charts are noise right now. Hashrate distribution by pool is the metric that actually predicts activation outcomes. If you see coordinated pool signaling above 50%, start thinking about exchange counterparty risk and potential withdrawal freezes during any contested activation window. That’s where the real exposure sits.

Frequently Asked Questions
What are red flags in crypto investments?
When navigating the cryptocurrency space, it is crucial to stay vigilant against common red flags. According to financial regulators, major warning signs include unsolicited loan offers, excessive margin trading options, or platforms promising to “match” your funds to double or triple your investment. Fraudulent platforms often guarantee unrealistically high returns with little to no risk. Especially during times of network hype or technical controversy—such as the recent power struggles over Bitcoin anti-spam proposals—scammers capitalize on investor confusion. Always remember that in crypto, you cannot get something for nothing. If an investment opportunity relies on manipulated data or seems too good to be true, it is likely a scam.
How do I verify a crypto exchange’s legitimacy?
Verifying a crypto exchange requires careful research and due diligence. Start by checking if the platform is registered with official regulatory bodies, such as searching the FinCEN MSB registrant database in the United States. While registration alone does not guarantee absolute protection against fraud, the vast majority of scams involve unregistered people and products. Be highly suspicious of platforms with no physical address, clearly fake contact details, or those operating entirely offshore with zero operational transparency. Just as the Bitcoin network relies on genuine, verifiable nodes rather than “faked” sybil entities to maintain its integrity, you must demand verifiable credentials from any platform handling your digital wealth.
What is the Bitcoin anti-spam proposal and why is it causing a power struggle?
The Bitcoin anti-spam proposal is a contentious network discussion aimed at filtering out non-financial “spam” data, such as Ordinals (NFTs) and BRC-20 tokens, from the blockchain. Proponents of the proposal argue that these data-heavy transactions bloat the network, slow down transaction times, and artificially drive up fees for everyday users trying to send money. This has ignited a fierce power struggle within the Bitcoin ecosystem. On one side are network purists who believe Bitcoin should strictly function as a peer-to-peer electronic cash system. On the opposing side are miners who profit immensely from the increased transaction fee revenue, as well as developers who argue that Bitcoin’s base layer must remain entirely permissionless and uncensored.
What does it mean when Bitcoin nodes are ‘faked’ or spoofed?
‘Faking’ or spoofing Bitcoin nodes involves spinning up thousands of cheap, virtual, or cloud-based nodes that do not process meaningful economic activity or contribute to true network consensus. In the context of the recent anti-spam power struggle, malicious actors use these fake nodes to artificially inflate signaling numbers. Their goal is to create a false illusion of massive grassroots community support (or opposition) for a specific protocol change. By manipulating these node counts, actors attempt to hijack Bitcoin’s decentralized governance process, making it difficult for developers to gauge true economic consensus and highlighting the dangers of relying solely on raw node metrics.
