`@hyperledger/cactus-plugin-ledger-connector-sawtooth`

This plugin provides Cacti a way to interact with Sawtooth networks. Using this we can perform:

Check plugin and sawtooth node status.
Monitor new blocks and transactions on the ledger.

Summary

@hyperledger/cactus-plugin-ledger-connector-sawtooth

Getting Started

Clone the git repository on your local machine. Follow these instructions that will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

In the root of the project to install the dependencies execute the command:

npm run configure

Usage

Before running the connector please ensure that Sawtooth node is running and that connector will have direct access to it. Access through a proxy is not supported yet (see https://sawtooth.hyperledger.org/docs/1.2/sysadmin_guide/rest_auth_proxy.html). To use this import public-api and create new PluginLedgerConnectorSawtooth.

const connector = new PluginLedgerConnectorSawtooth({
  instanceId: uuidV4(),
  logLevel: testLogLevel,
  sawtoothRestApiEndpoint: ledgerRestApi,
  watchBlocksPollTime,
});

You can make calls through the connector to the plugin API:

async getStatus(): Promise<StatusResponseV1>

Please note that deployContract() and transact(), although available to call, are not implemented and will throw error on runtime!

SawtoothApiClient

All connector API endpoints are defined in open-api specification. You can use SawtoothApiClient to call remote sawtooth connector functions. It also contain additional utility functions to ease integration.

REST Functions

See DefaultApi for up-to-date listing of supported endpoints.

getStatusV1

Asynchronous Functions (socket.io)

watchBlocksV1

Running the tests

To check that all has been installed correctly and that the plugin has no errors run jest test suites.

Run this command at the project's root:

npx jest cactus-plugin-ledger-connector-sawtooth

This plugin uses Sawtooth REST API OpenAPI specification from https://sawtooth.hyperledger.org/docs/1.2/rest_api/openapi/. We did some changes to the original spec in order to simplify request handling (e.g. change type, mark fields as requried, etc...)
