neo-go Go Node and SDK for the NEO blockchain.
Go Node and SDK for the NEO blockchain.
This project aims to be a full port of the original C# Neo project. A complete toolkit for the NEO blockchain, including:
This branch (master) is under active development now (read: won't work out of the box) and aims to be compatible with Neo 3. For the current stable version compatible with Neo 2 please refer to the master-2.x branch and releases before 0.80.0 (0.7X.Y track). Releases starting from 0.90.0 contain Neo 3 code (0.90.0 being compatible with Neo 3 preview2).
neo-go uses GoModules as dependency manager:
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
20332 for the
Build the neo-go CLI:
Quick start a NEO node on the private network. This requires the neo-privatenet Docker image running on your machine.
To run the binary directly:
By default the node will run on the
private network, to change his:
./bin/neo-go node --mainnet
Available network flags:
If you want to jump-start your mainnet or testnet node with chain archives provided by NGD follow these instructions (when they'd be available for 3.0 networks):
$ wget .../chain.acc.zip # chain dump file $ unzip chain.acc.zip $ ./bin/neo-go db restore -m -i chain.acc # for testnet use '-t' flag instead of '-m'
The process differs from the C# node in that block importing is a separate mode, after it ends the node can be started normally.
Please refer to neo-go smart contract development workshop that shows some simple contracts that can be compiled/deployed/run using neo-go compiler, SDK and private network. For details on how Go code is translated to Neo VM bytecode and what you can and can not do in smart contract please refer to the compiler documentation.
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.

The blockchain is the decentralized database of the blocks of information, which gets recorded in the chain format and linked in a secured crypto graphical manner. This technology ensures proper safety of the data due to its secure nature, and it totally changes how people carry out transactions. It also brings about a faster and secure process of validating information needed to establish reliability.
Training courses for blockchains have become very popular. The software is evolving to become part of the mainstream scheme. The growing need for a safe and secure system is one of the main reasons for this. It also contributed to one of the...
