Who Rewrites Bitcoin? Inside Saylor's Constitutional Case and the Fee Market Blind Spot

Michael Saylor sees a threat, and it is not coming from where the market expects. Hackers, regulators, hostile governments — none of these worry the Strategy chairman. The real danger to Bitcoin, he argues, is internal: the people trying to rewrite the rules from within. He has indicted three proposals with a single hammer. BIP-110, a temporary soft fork that would limit data field sizes to curb blockchain bloat. The covenant family — CTV, CAT, and their kin — promising richer script capabilities for vaults and atomic transactions. And the perennial push for larger blocks. Different mechanisms, different risk profiles, different philosophical roots. Saylor calls all three violations of Bitcoin's unwritten constitution. The backdrop matters, and it starts with a map. BIP-110 is a restrictive change. It shrinks the space for non-payment data, a direct response to the Ordinals inscription wave that has consumed blockspace with everything from JPEGs to text. Its supporters frame it as a return to Satoshi's original vision: peer-to-peer electronic cash, not a decentralized data warehouse. Its opponents — and I count myself among the skeptical here — see a gatekeeper move disguised as maintenance. Who decides which transactions are "legitimate"? Once that question has an answer, the network has quietly accepted a censor. In 2017, sitting in a Tokyo apartment, I spent three months manually auditing ICO smart contracts, hunting for logic flaws hidden in the subtle interactions between otherwise reasonable functions. I found three critical ones in a decentralized storage project's token distribution mechanism. That experience taught me something that has shaped every protocol judgment I have made since: the most dangerous rules are never the explicit ones. They are the ones that change who can participate, silently, without a headline. That is why I take Saylor's warning seriously, even when I disagree with where he points the finger. Covenants are a different creature entirely. They expand Bitcoin Script's expressiveness — enabling vaults, atomic swaps, and more complex contract patterns than the network has ever supported. The promise is genuine. So is the cost. Every new expressive capability introduces a new class of edge cases. I have seen what happens when complexity grows faster than our ability to reason about it: bugs that survive three audits, exploits that live in the interaction layer rather than on the obvious surface. Saylor says covenants would "permanently increase consensus complexity and introduce new attack surfaces." It is the same calculation I reach after a long staring contest with code. He is not wrong. But here is where his argument gets interesting. Saylor's sharpest weapon is the fee market thesis. Bitcoin's miners earn from two streams: block subsidies that are programmed to decay every four years through halvings, and transaction fees. The next halving cuts deeper. Fees must eventually carry the security budget alone. Weaken the fee market — by diluting scarcity or filtering out high-value transactions — and you starve the soldiers protecting the network. Tracing the code back to the conscience, his framing is an ethical one: the fee market is the network's moral economy, the incentive structure that pays the invisible army keeping the ledger honest. The logic chain is elegant: lower fees, lower miner revenue, lower hash rate, weaker security. It is the most coherent defense of Bitcoin's status quo that exists, and it deserves more respect than the innovation-first crowd usually grants it. But precision matters. BIP-110, covenants, and larger blocks are not the same kind of change. BIP-110 restricts what counts as a transaction. Covenants expand what transactions can do. They lie on opposite ends of the governance spectrum. One reduces the attack surface; the other grows it. Anointing both as constitutional violations gives away the game: Saylor's real principle is simply that change itself is the threat. That is a position. It is also the position of a man whose company holds over 400,000 BTC — the largest corporate balance sheet in the ecosystem. He is not a neutral constitutional scholar. He is a stakeholder, and stakeholders must be audited too. Open books, open ledgers, open hearts is an ethos of transparency, after all, and that applies to treasuries as much as to transactions. The fee market logic also has a blind spot, and it is the same one economics students are trained to catch: the assumption that the price of blockspace and the demand for it move in lockstep. Saylor treats the fee pool as a function of unit fees. But fee pools are elastic. Ethereum's fee market has grown through multiple cycles even as gas prices swung wildly, because transaction volume expanded. If BIP-110 concentrates payment traffic into scarce blockspace, short-term miner revenue may actually improve. The proposal's true losers are data-heavy applications — the Ordinals builders and inscribers — not ordinary senders. By framing BIP-110 as a universal threat rather than a targeted trade-off, Saylor skips the very analysis his economics training should demand. Then there is the cultural question, the one no BIP can resolve. Bitcoin's blockspace was purely financial for a decade. Then Ordinals arrived, and people started inscribing art, anchoring identities, storing digital memories. This wave of cultural expression is messy and sometimes absurd. But it is also culture — and culture is the ultimate consensus mechanism. Saylor would like to classify those uses as noise. I have been on the other side of that coin. When my co-founders and I launched Neo-Tokyo Punks, we used NFTs to bridge Edo-period art with generative AI, raising money for museum conservation. We saw what happens when people attach meaning to digital artifacts. That meaning is not a bug. It is the system working. Saylor's constitution metaphor has one weakness that every constitution shares: constitutions are living documents, or they become museum pieces. The question is not whether Bitcoin changes. The question is who gets a voice when change is on the table. In 2017, the block size war was settled by a brutal combination of market pressure and community exhaustion. The same debate is now replaying in different costumes. Building bridges where others build walls is what evangelists do, but it is also what ordinary users do when they find new meaning in old rails. Bitcoin stands at a crossroads between being a fortress and being a foundation. It can be both, but only if the community understands that stability without evolution is its own kind of attack. The audit is not the end, but the beginning. We are in a sideways market, and chop is for positioning. For those watching closely, the signal is not in the price chart. It is in the governance debate — in who is allowed to speak, who is dismissed as noise, and whether the rulebook can bend without breaking. That is the trade that matters.
