Module Tezos_raw_protocol_013_PtJakart.Operation_reprSource

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
  • tx rollup origination
  • tx rollup batch submission
  • tx rollup commit
  • tx rollup withdraw
  • tx rollup reveal withdrawals
  • smart contract rollup origination

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.

Sourcetype 'kind operation = {
  1. shell : Tezos_protocol_environment_013_PtJakart.Operation.shell_header;
  2. protocol_data : 'kind protocol_data;

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

Sourceand 'kind protocol_data = {
  1. contents : 'kind contents_list;
  2. signature : Tezos_protocol_environment_013_PtJakart.Signature.t option;

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

Sourceand _ contents_list =
  1. | Single : 'kind contents -> 'kind contents_list
  2. | Cons : 'kind Kind.manager contents * 'rest Kind.manager contents_list -> ('kind * 'rest) Kind.manager contents_list

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.

A manager_operation describes management and interactions between contracts (whether implicit or smart).

Counters are used as anti-replay protection mechanism in manager operations: each manager account stores a counter and each manager operation declares a value for the counter. When a manager operation is applied, the value of the counter of its manager is checked and incremented.
