How this market settles

This market will resolve to “Yes” if, by December 31, 2026, 11:59 PM ET, a quantum-resistant protocol upgrade is activated on the Bitcoin mainnet. Otherwise, this market will resolve to “No.” To qualify, the upgrade must satisfy all of the following: - The upgrade must constitute a consensus-layer change to the Bitcoin protocol that is live and enforced on the Bitcoin mainnet by the deadline. Proposals, drafts, code releases, miner signaling, node adoption, or activation on testnets or alternative networks do not qualify on their own. - The upgrade must enable the use of a post-quantum-secure signature scheme for standard Bitcoin transactions on the Bitcoin mainnet. The scheme must be intended to provide meaningful resistance against quantum attacks on transaction signing (e.g., attacks against ECDSA or successor schemes). Purely theoretical proposals, wallet-level changes, off-chain solutions, layer-2 systems, or other non-consensus-layer mitigations do not qualify. - The upgrade must make such quantum-resistant transaction types valid under Bitcoin consensus rules and generally available for use on the Bitcoin mainnet, even if their use is optional or not yet widely adopted. “Activated” means the upgrade has reached the point at which its rules are enforced on Bitcoin mainnet blocks under consensus rules, following any required activation thresholds or lock-in periods. The resolution source will be a consensus of credible reporting.

What could still go wrong

  • Resolution source is defined as 'a consensus of credible reporting,' which is subjective and undefined — no specific authoritative sources (e.g., Bitcoin Core releases, specific news outlets) are named, leaving room for dispute about what constitutes credible consensus.
  • The term 'meaningful resistance against quantum attacks' is subjective and could be disputed if a proposed scheme is contested in the cryptographic community as insufficiently quantum-resistant.
  • The phrase 'generally available for use on the Bitcoin mainnet' lacks a precise technical definition — it is unclear what threshold of availability satisfies this condition.
  • 'Standard Bitcoin transactions' is not precisely defined, potentially creating ambiguity about whether a new transaction type counts as 'standard.'
  • No specific BIP number or upgrade mechanism is referenced, so evaluators must judge whether any given upgrade qualifies based on the criteria, introducing interpretation risk.
  • Timezone boundary: 'December 31, 2026, 11:59 PM ET' maps to 2027-01-01T04:59:00Z, which matches the end date, but ET daylight saving ambiguity (EST vs EDT) could affect exact cutoff though December 31 would be EST (UTC-5), so this appears consistent.

    Against yes

    In the proposed system, if a hacker uses a quantum computer to derive an old private key and attempts to transfer funds, they must first lock up collateral from their quantum-resistant wallet
