Quantum vulnerability and the governance of Satoshi era keys

The theoretical emergence of cryptographically relevant quantum computing poses a direct threat to roughly 1.7 million BTC held in early addresses. These legacy wallets, primarily from the Satoshi era, utilise Pay-to-Public-Key (P2PK) scripts that expose public keys directly on the ledger. A sufficiently powerful quantum computer could derive the corresponding private keys from these public records, effectively granting an attacker the ability to sign transactions for coins that have remained dormant for over a decade.

While the market implications of a 145 billion dollar supply shock are often framed as existential, the technical reality is more nuanced. Current market data suggests that Bitcoin liquidity pools regularly absorb similar volumes of sell side pressure. During active market cycles, long term holders frequently distribute tens of thousands of BTC daily, and exchange inflows often reach nearly one million BTC per month. The volume of the vulnerable P2PK supply is equivalent to approximately three months of typical profit taking. From a purely mechanical perspective, the market possesses the depth to process this transition, provided the distribution is not instantaneous.

However, the true risk is not found in price volatility, but in the trust assumptions required to mitigate the threat. The proposed solutions to protect these dormant funds involve fundamental shifts in Bitcoin governance. Proposals such as BIP-361 suggest a path toward freezing or restricting these vulnerable coins to prevent unauthorised spend by quantum adversaries. This introduces a dangerous precedent for the network. If a majority of nodes agree to invalidate specific UTXOs based on their cryptographic vulnerability, the core promise of censorship resistance is compromised.

The sovereignty of the network rests on the principle that only the holder of the private key can authorise a movement of funds. If the community moves to freeze the Satoshi era coins, it assumes a custodial role over the ledger, deciding which property rights are valid and which are forfeit. This creates a centralisation of authority that mirrors the legacy financial systems Bitcoin was designed to replace. The dilemma is clear: allow a quantum attacker to potentially liquidate the supply, or grant the developer and node class the power to determine who is allowed to spend their bitcoin.

Zero Trust requires acknowledging that any mechanism capable of freezing 'vulnerable' coins is a mechanism that can be used to freeze any coins. The preservation of the protocol's integrity is more vital than the market value of the assets it carries. If the keys are compromised by physics, the network must adapt its cryptography, not its commitment to permissionless ownership.
