BIP-110 Explained: A Beginner’s Guide to Bitcoin’s Anti-Spam Fork Debate
Is Bitcoin’s plan to block “spam” transactions actually more dangerous than the problem it’s trying to solve? That’s the core question dividing the Bitcoin community as BIP-110—a controversial anti-spam fork—nears activation. Michael Saylor, executive chairman of Strategy (the largest corporate Bitcoin holder), fired back at the proposal, warning it sets a “dangerous precedent.” He argued there are “110 things more dangerous to Bitcoin than spam.” For everyday crypto users, this debate is about more than just technical rules—it’s about the fundamental philosophy of what Bitcoin should be. This guide breaks down what BIP-110 actually proposes, why industry leaders are split, and what it means for your Bitcoin transactions and fees.

Understanding Bitcoin Improvement Proposals (BIPs) for Beginners
A Bitcoin Improvement Proposal (BIP) is a formal design document that proposes new features, processes, or changes to the Bitcoin network. Think of it like a suggestion box for the entire Bitcoin community. Anyone can submit a BIP, but for it to become active, miners (who process transactions) and node operators (who validate blocks) must reach consensus and adopt the new rules.
Simple Definition: A BIP is a standardized way for developers, miners, and the community to propose and debate upgrades to Bitcoin’s code.
Why was this created? Bitcoin is decentralized—there’s no CEO or central authority to make decisions. The BIP process creates a structured, transparent way for thousands of independent participants to agree on changes. Without it, upgrades could become chaotic or lead to network splits (forks).
Everyday Analogy: Imagine your neighborhood has no HOA or city council. If someone wants to change the street signs, they can’t just do it alone. They write a proposal (a BIP), post it in the community center, and ask neighbors to vote. If 90% agree, they change the signs. If only 30% agree, there’s a risk of “forks”—two different sign systems that confuse everyone.
Real-world example: The most famous BIPs include SegWit (BIP 141) , which increased Bitcoin’s transaction capacity, and Taproot (BIP 341) , which improved privacy and smart contract capabilities. Both went through years of debate and gradual adoption.
The Technical Details: How BIP-110 Actually Works
BIP-110 proposes to “temporarily limit the size of data fields at the consensus level” to reduce spam on the Bitcoin network. Here’s what that means in plain language:
1. Targeting Inscriptions (Ordinals): The primary target is data inscriptions, popularized by Ordinals—a protocol that allows users to embed arbitrary data (like images, text, or NFTs) directly onto Bitcoin transactions. Critics call this “spam” because it clogs blockspace with non-monetary data.
2. Consensus-Level Limit: BIP-110 would change Bitcoin’s core rules (consensus) to restrict how much extra data can be included in a transaction. This is not a soft suggestion—it would make some currently valid transactions invalid under the new rules.
3. Temporary Implementation: The proposal is advertised as a “temporary” fix to correct “distorted incentives caused by standardizing support for arbitrary data.” The idea is to cool down the Ordinals trend until the community agrees on a more permanent solution.
4. Miner & Node Signaling: For BIP-110 to activate, a majority of Bitcoin’s mining hash rate (computing power) must signal support. As of July 2026, only about 5 EH/s (exahashes per second) have signaled—a tiny fraction of Bitcoin’s total ~600 EH/s. This suggests the proposal may not have enough support to activate.
Why this structure matters: Changing Bitcoin’s consensus rules is a monumental task. Even a small change requires massive coordination and can create a “fork” if a significant minority rejects the change. This is why Saylor warns about “invalidating currently valid, fee-paying transactions.”
Current Market Context: Why This Matters Now
As of July 2026, the Ordinals phenomenon has been a double-edged sword for Bitcoin. On one hand, it has driven record transaction fees (miners earned over $1 billion in inscription-related fees in 2025). On the other, it has clogged blocks, causing average transaction confirmation times to spike during peaks.
Key data points:
- Bitcoin’s average fee in mid-2026 is around $2–$5 per transaction, far lower than the $50+ seen during 2023 Ordinals peaks.
- Market context: The broader crypto market has rallied, with Bitcoin trading near $64,000 and the Crypto Fear & Greed Index at “26 (Fear)”—suggesting cautious sentiment despite recent gains.
- Institutional interest: BlackRock and VanEck led $90 million in Bitcoin ETF inflows in late July, indicating sustained institutional demand despite the BIP-110 debate.
Why this matters now: The debate is not about an immediate crisis. Fees are low, and the network is functioning normally. But the philosophical divide is widening: purists want Bitcoin to remain strictly “digital gold” for monetary transactions only, while others see inscriptions as a legitimate use of block space.
Competitive Landscape: How Key Figures Compare
The debate over BIP-110 has created clear factions among Bitcoin’s most influential voices:
| Position | Michael Saylor (Strategy) | Luke Dashjr (Ocean Mining) | Adam Back (Blockstream) |
|---|---|---|---|
| Stance on BIP-110 | Strongly opposed—calls it “dangerous precedent” | Strongly supports—seeks to limit non-monetary data | Opposed—calls it “not grounded” and in conflict with permissionless money |
| Main Argument | “Spam is not a problem; the free market solves blockspace” | “Inscriptions distort incentives; consensus change needed” | “Anti-spam rules conflict with free, permissionless money” |
| Philosophy | Bitcoin as store of value; embrace all fee-paying uses | Bitcoin as pure money; non-monetary data harms network | Bitcoin as cypherpunk money; minimal consensus changes |
| User Impact Concern | Valid transactions becoming invalid | Blockspace being wasted on non-monetary data | Losing users disillusioned by changes |
Why this matters: These aren’t minor disagreements. They reflect three fundamentally different visions for Bitcoin’s future—as a digital gold (Saylor), as pure monetary protocol (Dashjr), or as permissionless value transfer (Back).
Practical Applications: Real-World Use Cases
How might BIP-110 affect your daily crypto experience?
- Transaction Fees: If BIP-110 succeeds, spam (inscriptions) would decrease, potentially reducing fees during peaks. Your transaction might confirm faster. User segment: Regular senders/receivers.
- NFTs on Bitcoin: If you hold Ordinals-based NFTs, BIP-110 could make transactions involving them invalid under new rules. You’d need to migrate to other blockchains. User segment: NFT collectors.
- Miner Revenue: Miners earning fees from inscriptions could see a revenue drop. This might push smaller miners out of business, increasing centralization. User segment: Mining pool participants.
- Development Innovation: Other projects building on Bitcoin (like layer-2 solutions) might be discouraged if consensus changes become unpredictable. User segment: Developers, protocol investors.
Risk Analysis: Expert Perspective
Primary Risks:
1. Fragmentation Risk: If BIP-110 activates without overwhelming consensus, it could split the Bitcoin network. Users on the old rules (non-BIP-110) and new rules (BIP-110) would have incompatible transaction sets. This is exactly what Saylor warns about.
2. Invalidation of Valid Transactions: By changing consensus to block inscriptions, BIP-110 would retroactively make some transactions invalid. This sets a precedent that “the consensus can flip at any time”—a scary thought for users relying on Bitcoin’s predictability.
3. Erosion of Permissionless Ethos: Adam Back criticizes the proposal as conflicting with “free cypherpunk permissionless money.” If Bitcoin starts policing what data you can include, where does it stop? Who decides what “spam” is?
Mitigation Strategies:
- User education: Understand the implications before signaling your support (miners) or adjusting your usage.
- Diversify: If you use Bitcoin for inscriptions, consider multi-chain strategies (e.g., Ethereum, Litecoin) to reduce exposure.
- Monitor signaling: BIP-110 currently has extremely low hashrate support (~5 EH/s out of 600+). It likely won’t activate soon, but keep an eye on the signal.
Historical Precedent: The Bitcoin Cash (BCH) fork in 2017 is a cautionary tale. A philosophical disagreement about block size led to a permanent split, confusing users and fragmenting the community. BIP-110 risks repeating that pattern.
Future Outlook: What’s Next
The BIP-110 story is far from over. Here’s what to watch:
1. Miner Signaling (Q3–Q4 2026): With only 5 EH/s currently supporting, the proposal needs a massive increase. If major mining pools (like Foundry or Antpool) signal support, the activation timeline accelerates toward August 2026.
2. Community Consensus: Key figures like Saylor, Back, and Jameson Lopp (Casa CSO) have dismissed BIP-110 as a “nothingburger.” But if the Ordinals craze returns and fees spike again, support could grow.
3. Alternative Solutions: Instead of a controversial hard fork, the community may shift toward second-layer solutions like RGB or Taproot Assets that handle inscriptions without clogging the base layer.
4. Regulatory Attention: If the debate escalates, global regulators (SEC, ESMA under MiCA) may weigh in on what constitutes legitimate Bitcoin use. This could force a compromise.
The most likely scenario: After months of debate, BIP-110 will either fail to reach activation threshold or be replaced by a more nuanced proposal (e.g., a fee-based economic disincentive rather than a consensus ban).
Key Takeaways
- BIP-110 proposes temporarily limiting data fields on Bitcoin to reduce Ordinals-style inscriptions, but critics warn it sets a dangerous precedent of invalidating valid transactions.
- Michael Saylor argues spam is not a current problem and that the free market handles blockspace challenges better than consensus changes.
- Miners have signaled minimal support (~5 EH/s) , suggesting the fork is unlikely to activate soon without a major shift in community sentiment.
- The core conflict is philosophical: should Bitcoin be “digital gold” for monetary use only, or “permissionless money” embracing all data?
