Roman Khimov 292051d8df core: get transactions from dao when mempool should not be used
All of these places deal strictly with the chain and shouldn't ever be
bothered with mempool. It also fixes a deadlock on reverification of
non-standard tx:

Go Node and SDK for the NEO blockchain.


codecov CircleCI Report GoDoc GitHub release (latest SemVer) License

Overview

This project aims to be a full port of the original C# NEO project. A complete toolkit for the NEO blockchain, including:

Getting started

Installation

Go: 1.12+

Install dependencies.

neo-go uses GoModules as dependency manager:

make deps

How to setup a node

Docker

Each tagged build is built to docker hub and the :latest tag pointing at the latest tagged build.

By default the CMD is set to run a node on testnet, so to do this simply run:

 docker run -d --name neo-go -p 20332:20332 -p 20333:20333 cityofzion/neo-go

Which will start a node on testnet and expose the nodes port 20333 and 20332 for the JSON-RPC server.

Building

Build the neo-go CLI:

make build

Quick start a NEO node on the private network. This requires the neo-privatenet Docker image running on your machine.

make run

To run the binary directly:

./bin/neo-go node

By default the node will run on the private network, to change his:

./bin/neo-go node --mainnet

Available network flags:

  • --mainnet, -m
  • --privnet, -p
  • --testnet, -t

#Developer notes Nodes have such features as Prometheus and Pprof in order to have additional information about them for debugging.

How to configure Prometheus or Pprof: In config/protocol.*.yml there is

  Prometheus:
    Enabled: true
    Port: 2112

where you can switch on/off and define port. Prometheus is enabled and Pprof is disabled by default.
