dauTT 095653af23 Implement rpc server method: sendrawtransaction (#174) 
* Added new config attributes: 'SecondsPerBlock','LowPriorityThreshold'

* Added new files:

* Added new method: CompareTo

* Fixed empty Slice case

* Added new methods: LessThan, GreaterThan, Equal, CompareTo

* Added new method: InputIntersection

* Added MaxTransactionSize, GroupOutputByAssetID

* Added ned method: ScriptHash

* Added new method: IsDoubleSpend

* Refactor blockchainer, Added Feer interface, Verify and GetMemPool method

* 1) Added MemPool
2) Added new methods to satisfy the blockchainer interface: IsLowPriority, Verify, GetMemPool

* Added new methods: RelayTxn, RelayDirectly

* Fixed tests

* Implemented RPC server method sendrawtransaction

* Refactor getrawtransaction, sendrawtransaction in separate methods

* Moved 'secondsPerBlock' to config file

* Implemented Kim suggestions:
1) Fixed data race issues
2) refactor Verify method
3) Get rid of unused InputIntersection  method due to refactoring Verify method
4) Fixed bug in https://github.com/CityOfZion/neo-go/pull/174#discussion_r264108135
5) minor simplications of the code

* Fixed minor issues related to

1) space
2) getter methods do not need pointer on the receiver
3) error message
4) refactoring  CompareTo method in uint256.go

* Fixed small issues

* Use sync.RWMutex instead of sync.Mutex

* Refined (R)Lock/(R)Unlock

* return error instead of bool in Verify methods

neo-go

Go Node and SDK for the NEO blockchain.

Overview

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

  • consensus node
  • RPC node & client
  • RPC client
  • CLI tool
  • Smart contract compiler
  • NEO virtual machine

Getting started

Installation

Install dependencies.

neo-go uses dep as its dependency manager. After installing deps you can run:

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 -seed 127.0.0.1:20333,127.0.0.1:20334

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

If you want in-depth customization for your node, there are yaml config files for each network available in the config directory. Those files are automatically loaded, corresponding the provided netmode flag.
