Each proposer requires to lock a bond, currently set to 0.5 ETH, that can be slashed if any proposal made by them is proven incorrect via a fault proof or a conflicting validity proof. The bond can be withdrawn once the proposer has no more pending proposals that need to be resolved and was not eliminated.\n\nProposals consist of a state root and a reference to their parent and implicitly challenge any sibling proposals who have the same parent. A proposal asserts that the proposed state root constitutes a valid state transition from the parent's state root. To offer efficient zk fault proofs, each proposal must include 3600 intermediate state commitments, each spanning 6 L2 blocks. \n\nProposals target sequential tournament epochs of currently 3600 * 6 L2 blocks. A tournament with a resolved parent tournament, a single child- and no conflicting sibling proposals can be resolved after 3d. \n\nThe **Vanguard** is a privileged actor who can always make the first child proposal on a parent state root. They can, in the worst case, delay each tournament for up to 1mo by not making this first proposal. Sibling proposals made after the Vanguard's initial one or after the 1mo vanguardAdvantage in each tournament are permissionless.",

These children are indirectly challenging each other in a tournament, which can only be resolved if but a single child survives. A state root can be resolved if it is **the only remaining proposal** due to any combination of the following elimination methods: \n1. the proposal's challenge period of 3d has ended before a conflicting proposal was made\n2. the proposal is proven correct with a full validity proof (invalidates all conflicting proposals)\n3. a conflicting sibling proposal is proven faulty\n\nProving any of the 3600 intermediate state commitments in a proposal faulty invalidates the entire proposal. Proving a proposal valid invalidates all conflicting siblings. Pruning of a tournament's children happens strictly chronologically, which guarantees that the first faulty proposal of a given proposer is always pruned first. When pruned, an invalid proposal leads to the elimination of its proposer, which invalidates all their subsequent proposals, slashes their bond, and disallows future proposals by the same address. A slashed bond is transferred to an address chosen by the prover who caused the slashing.\n\nA single remaining child in a tournament can be 'resolved' and will be finalized and usable for withdrawals after an execution delay of 1d (time for the Guardian to manually blacklist malicious state roots).",

But two different zk proofs on unresolved state roots are possible and permissionless: The proveValidity() function proves a state root proposal's full validity, automatically invalidating all conflicting sibling proposals. proveOutputFault() allows any actor to eliminate a state root proposal for which they can prove that any of the 3600 intermediate state transitions in the proposal are not correct. Both are zk proofs of validity, although one is used as an efficient fault proof to invalidate a single conflicting state transition.",

These children are indirectly challenging each other in a tournament, which can only be resolved if but a single child survives. A state root can be resolved if it is **the only remaining proposal** due to any combination of the following elimination methods: \n1. the proposal's challenge period of 7d has ended before a conflicting proposal was made\n2. the proposal is proven correct with a full validity proof (invalidates all conflicting proposals)\n3. a conflicting sibling proposal is proven faulty\n\nProving any of the 3600 intermediate state commitments in a proposal faulty invalidates the entire proposal. Proving a proposal valid invalidates all conflicting siblings. Pruning of a tournament's children happens strictly chronologically, which guarantees that the first faulty proposal of a given proposer is always pruned first. When pruned, an invalid proposal leads to the elimination of its proposer, which invalidates all their subsequent proposals, slashes their bond, and disallows future proposals by the same address. A slashed bond is transferred to an address chosen by the prover who caused the slashing.\n\nA single remaining child in a tournament can be 'resolved' and will be finalized and usable for withdrawals after an execution delay of 3d 12h (time for the Guardian to manually blacklist malicious state roots).",
