Run as a node

Run gonex

../_images/runs-gonex.png

All basic configuration parameters were set when launching the file gonex.exe, but you need running as following below configuration for the stable system:

Window:

> gonex --datadir "C:\gonex\data" --rpc --rpcapi "web3,net,eth" --rpccorsdomain "*,https://vnbig.com" --ethstats "vnbig:nty2018@stats.nexty.io" console

Linux:

> sudo ./gonex --datadir "/home/{user_name}/gonex_data" --rpc --rpcapi "web3,net,eth" --rpccorsdomain "*, https://vnbig.com" --ethstats " vnbig:nty2018@stats.nexty.io" console

Connection peers

By default, gonex will automatically connect to other peers in the nexty network (connection time is 2-10 minutes or faster), but in case it is blocked by firewall or other policies, you can manual connect to other peers by command are as follows:

  1. Add node manual by command:

  1. Add node by config file:

You can configure permanent static nodes by putting something like the following into file <datadir>/static-nodes.json (eg: Window: C:\Gonex\data\static-nodes.json; Linux: /home/{user}/gonex_data/), run gonex again.

  • String “pending” - for the pending state/transactions

Web3

  1. Create new wallet

Keythereum is a JavaScript tool to generate, import and export Ethereum keys. This provides a simple way to use the same account locally and in web wallets. It can be used for verifiable cold storage wallets.

Keythereum uses the same key derivation functions (PBKDF2-SHA256 or scrypt), symmetric ciphers (AES-128-CTR or AES-128-CBC), and message authentication codes as nexty. You can export your generated key to file, copy it to your data directory’s keystore, and immediately start using it in your local Ethereum client.

For detail see https://github.com/ethereumjs/keythereum
