Key Takeaways:
- BIP-361 aims to protect bitcoin from quantum computers, which McKinsey warns may emerge between 2027 and 2030.
- Frederic Fosco warns that freezing 35% of the supply would kill bitcoin’s monetary premium and gold status.
- Developers now weigh opt-in BIP-360 tools to offer 100% user sovereignty instead of mandatory coin sunsets.
The Scarcity Myth
The bitcoin community is currently locked in an ideological battle over BIP-361, a controversial proposal designed to shield the network from the looming shadow of quantum computing. On the surface, the math seems compelling: As quantum hardware advances toward the ability to crack legacy Elliptic Curve Digital Signature Algorithm (ECDSA) signatures, the network must migrate to quantum-resistant cryptography or risk a “silent drain” of its most storied addresses.
Critics, however, argue that the proposed cure—a mandatory freeze of non-migrated coins—is far more dangerous than the disease. At the heart of this debate lies a fundamental question: Is bitcoin a protocol of absolute property rights, or a system governed by the shifting consensus of its developers?
Still, some proponents point to a silver lining: a massive supply shock. If the 30% to 35% of bitcoin currently sitting in dormant or lost legacy addresses were to be permanently locked away, the remaining circulating supply would become significantly scarcer. In the vacuum of a spreadsheet, this looks like a guaranteed “scarcity pump.”
Frederic Fosco, co-founder of OP_NET, is not buying it. He views the scarcity argument as a psychological sleight of hand designed to mask a radical shift in bitcoin’s social contract.
“The scarcity pump framing is how you sell confiscation to people who should know better,” Fosco argues. “If a government seized 6 million BTC tomorrow and threw away the keys, that would also be ‘ bullish for scarcity.’ Nobody would celebrate it, because the mechanism matters more than the math.”
The real danger, according to skeptics, is not the technical difficulty of quantum computing but the destruction of bitcoin’s monetary premium. Bitcoin currently trades at a premium specifically because it is perceived as unstoppable money. If that immutability is compromised—even for the “noble” cause of security, as BIP-361 supporters frame it—the market’s perception of the asset could fundamentally shift.
Fosco warns that the consequences of such a move are currently being undermodeled by the market. The day the bitcoin network proves it can or will freeze wallets is the day it ceases to be “digital gold” in the eyes of institutional and sovereign holders.
“The consequence nobody is modeling is the monetary premium collapse,” Fosco says. “ Bitcoin trades where it does because the market believes the rules are immutable and property rights are absolute. The day bitcoin proves it will confiscate coins under sufficiently compelling circumstances, you haven’t made it scarcer; you’ve made it a different asset. One with a governance layer.”
Sovereignty Over Safety
Fosco suggests that the solution already exists in the form of opt-in technology. Protocols like BIP-360 and post-quantum signature schemes like ML-DSA offer a path forward that preserves user choice.
In this view, the role of developers is to provide the armor, not to force the soldiers to wear it. If a holder chooses to remain in a legacy address despite the availability of quantum-resistant alternatives, they are exercising their right to take a personal risk—a cornerstone of the “sovereign individual” philosophy.
“Stop trying to save people from themselves through consensus rules,” Fosco insists. “Quantum-resistant solutions exist right now. … Ship opt-in post-quantum address types, educate holders, build better wallets, make migration the obvious path. But never make someone’s bitcoin unspendable because they didn’t upgrade on your schedule.”
The fear is that once the line is crossed for quantum security, the precedent for coin freezing becomes an open door for traditional forms of financial censorship. If the protocol can be altered to freeze “at-risk” coins, it can be altered to freeze “sanctioned” or “politically incorrect” coins.
“If quantum breaks ECDSA tomorrow, the holders who didn’t migrate bear that risk. That’s their sovereign choice. Bitcoin’s job is to offer the tools, not enforce their use,” Fosco warns. “Cross that line and you’ve built a system that can freeze any coins for any reason deemed important enough. Today it’s quantum. Tomorrow it’s sanctions or dormancy taxes. Same principle.”
A Binary Choice
The BIP-361 debate highlights a growing rift in the digital gold narrative. If bitcoin adopts a governance layer capable of invalidating unspent transaction outputs ( UTXOs) based on their age or technical status, it moves closer to the world of traditional finance, where “edge cases” allow for the freezing of assets.
As the industry stares down the 2027–2030 window for quantum relevance, the community faces a binary choice. As Fosco bluntly puts it:
“Any short-term supply-shock rally gets dwarfed by the long-term repricing of what bitcoin actually is. You don’t get to be digital gold and a system that freezes dormant wallets. Pick one.”
While the threat of a covert quantum attack is a legitimate technical concern, the debate has revealed that bitcoin’s greatest security feature isn’t just its code—it’s its predictability. If the cost of quantum resistance is the death of “not your keys, not your coins,” many believe the price is simply too high to pay.
The battle for bitcoin’s future will not just be fought in the laboratories of quantum researchers, but in the minds of the holders who must decide if they value the math of scarcity over the sanctity of the rules.
