This market will resolve to "Yes" if the Fusaka upgrade is implemented on the Ethereum mainnet by December 31, 2025, 11:59 PM ET. Otherwise, this market will resolve to "No." Implementation means that Fusaka is live and functioning on the Ethereum mainnet, not merely announced, proposed, or deployed to a testnet. For the purposes of this market, "Fusaka" refers to any protocol, upgrade, application, or standard officially titled "Fusaka," or which is commonly referred to as "Fusaka" and includes EOF (EVM Object Format) or PeerDAS (Peer Data Availability Sampling). The primary resolution source for this market is the Ethereum blockchain, however a consensus of credible reporting may also be used.
