Agreement and Public State Changes​

The public state stored in the Gnosis Safe holds a pointer to the off-chain agreement. Any changes to the agreement or public state requires a signature from both parties to be sent to the Gnosis Safe. The pointer to the agreement is an IPLD CID (content identifier) that is stored in a Safe Module.

Private State Changes​

Changes to private state are done off chain and do not require a Gnosis Safe signature. Instead, changes require a signature from both parties directly and the state is stored off chain.

Each state contains a nonce. This nonce is included in the message and signed by each party. The state with the latest nonce that is signed by both parties is considered the current state.
