Accumuate API

Architecture

Modules

The Accumulate API is segmented into the following modules:

  • The Network module provides methods for querying network metadata such as TPS
  • The Node module provides methods for querying node metadata such as the node's software version.
  • The Query module provides methods for querying records.
  • The Submit module provides methods for submitting transactions.
Layers

The Accumulate API is composed of the following layers:

  • The Network layer executes Network requests by collating information from all network partitions.
  • The Node layer executes Node requests for a node.
  • The Database Query layer executes Query requests using a database.
  • The Tendermint Submit layer executes Submit requests by forwarding them to Tendermint RPC.
  • The Router layer executes Query and Submit requests by forwarding them to the appropriate network partition or data server.
Implementations
  • JSON-RPC
  • Binary
  • REST?

Methods

Query
  • QueryState(account, fragment..., options) queries the state of an account or an account fragment such as a transaction or other chain entry. QueryState can query at most one record at a time. Queries involving multiple records must use QuerySet.
  • QuerySet(account, fragment..., options) queies a set of records relating to an account, such as directory entries, transactions, etc.
  • Search(scope, recordQuery, options) searches for a record within the scope of an account or identity. For example, Search can locate a transaction on the main chain of any account within an ADI.
Submit
  • Submit(envelope, options) submits a transaction for execution. Submit can also be used to validate a transaction without submitting it.
  • Faucet(account, options) funds a lite account (for testnet only).
Network
  • Metrics() collects metrics from the entire network
Node
  • Status() returns the status of the node
  • Version() returns the software version of the node
  • Describe() returns the network configuration of the node
  • Metrics() collects metrics from the node
