DREP CLI

DREP Command Line Interface, a JSON-RPC based client for connecting to the DREP chain to query information on the chain and send transactions.

Features

Provides a decentralized ID system and data privacy protection
Integrates the underlying chain with both smart contracts and novel smart reputation pipes.
Provides the DREP reputation protocols and reputation templates.
Has high performance and high compatibilities.

Installation

Binaries (Windows/Linux/macOS)

Executable binaries can be downloaded from our GitHub page

Build from source code (all platforms)

Clone the repository into the appropriate $GOPATH/src/github.com/drep-project directory.

NOTE: requires Go >= 1.1.11.

  git clone https://github.com/drep-project/drepcli.git
  cd drepcli
  go install

Usage
