Module `Tezos_raw_protocol_alpha.Operation_repr`Source

Tezos Protocol Implementation - Low level Repr. of Operations

Defines kinds of operations that can be performed on chain:

preendorsement
endorsement
double baking evidence
double preendorsing evidence
double endorsing evidence
seed nonce revelation
account activation
proposal (see: Voting_repr)
ballot (see: Voting_repr)
failing noop
manager operation (which in turn has several types):
revelation
transaction
origination
delegation
set deposits limitation
smart rollup origination
smart rollup add messages
smart rollup publish
smart rollup cement
smart rollup refute
smart rollup timeout
smart rollup execute outbox message
smart rollup recover bond
zk rollup origination
zk rollup publish
zk rollup update

Each of them can be encoded as raw bytes. Operations are distinguished at type level using phantom type parameters. packed_operation type allows for unifying them when required, for instance to put them on a single list.

An operation contains the operation header information in shell and all data related to the operation itself in protocol_data.

Sourceand 'kind protocol_data = {

A protocol_data wraps together a signature for the operation and the contents of the operation itself.

A contents_list is a list of contents, the GADT guarantees two invariants:

the list is not empty, and
if the list has several elements then it only contains manager operations.

Each operation belongs to a validation pass that is an integer abstracting its priority in a block. Except Failing_noop.

Sourceval consensus_pass : int

The validation pass of consensus operations.

Sourceval voting_pass : int

The validation pass of voting operations.

Sourceval anonymous_pass : int

The validation pass of anonymous operations.

Sourceval manager_pass : int

The validation pass of anonymous operations.

Sourceval acceptable_pass : packed_operation -> int option

acceptable_pass op returns either the validation_pass of op when defines and None when op is Failing_noop.

Sourceval compare_by_passes : packed_operation -> packed_operation -> int

compare_by_passes orders two operations in the reverse order of their acceptable passes.

Source

val compare : 
  (Tezos_protocol_environment_alpha.Operation_hash.t * packed_operation) ->
  (Tezos_protocol_environment_alpha.Operation_hash.t * packed_operation) ->
  int

compare (oph1,op1) (oph2,op2) defines a total ordering relation on operations.

The following requirements must be satisfied: oph1 is the Operation.hash op1, oph2 is Operation.hash op2, and that op1 and op2 are valid in the same context.

compare (oph1,op1) (oph2,op2) = 0 happens only if Operation_hash.compare oph1 oph2 = 0, meaning when op1 and op2 are structurally identical.

Two valid operations of different validation_pass are compared according to acceptable_passes: the one with the smaller pass being the greater.

Two valid operations of the same validation_pass are compared according to a weight, computed thanks to their static information.

The global order is as follows:

Endorsement and Preendorsement > Dal_attestation > Proposals > Ballot > Double_preendorsement_evidence > Double_endorsement_evidence > Double_baking_evidence > Vdf_revelation > Seed_nonce_revelation > Activate_account > Drain_delegate > Manager_operation.

Endorsement and Preendorsement are compared by the pair of their level and round such as the farther to the current state level and round is greater; e.g. the greater pair in lexicographic order being the better. When equal and both operations being of the same kind, we compare their slot: the The smaller being the better, assuming that the more slots an endorser has, the smaller is its smallest slot. When the pair is equal and comparing an Endorsement]toa{!Preendorsement, the Endorsement is better.

Two Dal_attestation ops are compared in the lexicographic order of the pair of their number of endorsed slots as available and their endorsers.

Two voting operations are compared in the lexicographic order of the pair of their period and source. A Proposals is better than a Ballot.

Two denunciations of the same kind are compared such as the farther to the current state the better. For Double_baking_evidence in the case of equality, they are compared by the hashes of their first denounced block_header.

Two Vdf_revelation ops are compared by their solution.

Two Seed_nonce_relevation ops are compared by their level.

Two Activate_account ops are compared by their id.

Two Drain_delegate ops are compared by their delegate.

Two Manager_operations are compared in the lexicographic order of the pair of their fee/gas_limit ratios and source.

Sourceval unsigned_operation_length : _ operation -> int
