This market will resolve to “Yes” if any blockchain that existed prior to the creation of this market implements a quantum-resistance related protocol upgrade at any time after the creation of this market and before January 1, 2028 – 00:00 PST.

Otherwise, this market will resolve to “No.”

For the purposes of this market:

- An “existing blockchain” is defined as a public blockchain network that had launched mainnet prior to market deployment.

- A “quantum-resistance related upgrade” is defined as a protocol-level change that introduces or transitions to post-quantum cryptographic primitives (e.g., quantum-resistant signature schemes or key exchange mechanisms) intended to mitigate risks from quantum computing attacks.

- The upgrade must be activated on mainnet, and usable by the general public.

- Research proposals, testnet deployments, optional experimental features, or roadmap announcements do not qualify unless the upgrade is implemented on mainnet.

- Soft forks, hard forks, or coordinated network upgrades all qualify if they meet the above criteria.

- Only upgrades occurring after market deployment are eligible.
