-**Note**
-
-The `bytes32 bondId` can be constructed using the `keccak256` hash of a given identifier.
-For example, the `L2OutputOracle` can create a `bondId` by taking the `keccak256` hash of
-the `l2BlockNumber` associated with the output proposal since there will only ever be one
-outstanding output proposal for a given `l2BlockNumber`.
-This also avoids the issue where an output proposer can have multiple bonds if bonds were
-instead tied to the address of the output proposer.
-
-## Bond Manager Implementation
-
-Initially, the bond manager will only be used by the `L2OutputOracle` contract
-for output proposals in the attestation [dispute game](./dispute-game-interface.md). Since
-the attestation dispute game has a permissioned set of attestors, there are no
-intermediate steps in the game that would require bonds.
-
-In the future however, Fault-based dispute games will be introduced and will
-require bond management. In addition to the bond posted by the output proposer,
-bonds will be posted at each step of the dispute game. Once the game is resolved,
-bonds are dispersed to either the output challengers or defenders
-(including the proposer).
