Parameter Blockchain.5-GoodNode

include AbstractNode with type ev = Event.t with type value = Block.block
type value = Block.block

The type of the values for which consensus is being reached.

type ev = Event.t

The type of the events being handled.

type node_data

The protocol specific data stored by the node.

type t = (node_data, value) template

The type representing a node and its state. Consists of apllying the value and node_data to the template.

Create the initial state of a node.

  • parameter node_id

    the id to be assigned to the node

  • parameter neighbors

    the node's neighbors

  • parameter region

    the node's region

val handle : t -> ev -> t

Receives the state of a node and an event, returning the resulting state.

  • parameter node

    the state of a node

  • parameter event

    the event to be processed by the node

val compare : t -> t -> int

Compares two nodes. Returns whether they are in the same state.

  • parameter node1

    the state of a node

  • parameter node2

    the state of a node

val state : t -> value

Get the consensus target of a node.

  • parameter node

    the state of a node

val state_id : t -> int

Return an integer that identifies the state of the node.

  • parameter node

    the state of a node

val parameters : unit -> string

Return a JSON string containing the relevant parameters (and values) for the Node's consensus algorithm

val chain_height : t -> int

Obtain the height of the chain stored in the node.

  • parameter node
