package octez-smart-rollup-node-lib

process_head node_ctxt ~predecessor head changes the state of the inbox on disk to react to the operations contained in the block head (where predecessor is the predecessor of head in the L1 chain). It returns a tuple (inbox_hash, inbox, payload_hash, messages) where inbox is the new inbox and inbox_hash its hash, payload_hash is the hash of the merkelized payload for this inbox and messages are the serialized messages present in the block (with the internal messages added by the protocol).

same_as_layer_1 node_ctxt block node_inbox ensures that the rollup node agrees with the L1 node that inbox for block is node_inbox.

Serialize an external messages to the protocol representation. NOTE: so far, in all available protocols, this adds a tag '\001' at the beginning.

Returns the initial global inbox where level is the first level of the protocol with smart rollups.
