  "notes": "In July 2016, following the exploit of The DAO smart contract, the Ethereum community executed a hard fork (block 1,920,000) that reversed the hack by moving the drained funds to a recovery contract. A minority of the network rejected this fork on the grounds of immutability and continued validating the original, unaltered chain history; that continuing chain was renamed Ethereum Classic (ETC), while the forked chain retained the name Ethereum (ETH) and became the chain most commonly referred to today. Source: ethereum.org 'History of Ethereum' page (https://ethereum.org/en/history/#dao-fork), which states the DAO fork split the network and that 'the chain that rejected the bailout became Ethereum Classic.' This is corroborated by Etherscan/Wikipedia accounts of the July 2016 fork. No on-chain computation applies since this is off-chain historical evidence (evidence: panel per the brief)."
