Functions used by the baker

prepare_block global_state block_to_bake prepares a block by:

  • inferring the block timestamp
  • recovering the operations from the mempool if the block is a new proposal, or reusing the operations from block_to_bake's payload if the block is a reproposal
  • generating the seed nonce hash if needed
  • setting the vote for liquidity baking according to the per_block_vote_file
  • calling Block_forge.forge to forge the block
  • signing the block header
  • registering the seed nonce if needed

authorized_consensus_votes global_state unsigned_consensus_vote_batch records and returns the list of unsigned_consensus_vote authorized according to the Baking_highwatermarks. This function emits an event for each unauthorized consensus vote.

forge_and_sign_consensus_vote global_state branch unsigned_consensus_vote forges a consensus operation by encoding the operation consensus content from unsigned_consensus_vote with the branch and then sign it.

compute_round proposal round_durations computes the round from the current timestamp, the proposal's timestamp and the round_durations.

perform_action state action performs the given action using the state

Functions only needed for the baking_lib

sign_consensus_votes global_state unsigned_consensus_vote_batch recovers the authorized consensus votes by calling authorized_consensus_votes, then signs these operation by calling forge_and_sign_consensus_vote, and then creates a batch with Baking_state.make_signed_consensus_vote_batch.

inject_consensus_votes state signed_consensus_vote_batch injects consensus votes from signed_consensus_vote_batch.

update_to_level state level_update computes the delegate slots for the given level and the next one, computes round information by calling compute_round and updates the state accordingly.

val may_get_dal_content : Baking_state.state -> Baking_state.unsigned_consensus_vote -> Tezos_protocol_alpha.Protocol.Alpha_context.dal_content option Tezos_base.TzPervasives.tzresult Lwt.t

may_get_dal_content state unsigned_consensus_vote, if the DAL feature is enabled, recovers the attestable slots by calling Node_rpc.get_attestable_slots and computes the corresponding dal_content.
