Guide

Install COIN on Linux

The Linux release has the node and the command-line wallet. A handful of commands and you're on the network.

  1. Download the Linux release

    On the Download page, press Download for Linux, and note the SHA-256 hash published with it.

  2. Check the file

    $ sha256sum FILE

    Replace FILE with the file's name and compare the result with the published hash. They must match exactly.

  3. Unpack it

    $ tar -xf FILE

    Then cd into the folder it creates.

  4. Start the node

    $ ./coind

    It connects to the network and downloads the blockchain. To keep it running in the background instead, start it with ./coind --detach and check on it any time with ./coind status.

  5. Create a wallet

    In a second terminal, start the command-line wallet from the same folder. It asks for a name for your wallet file, a password and a language, then shows your 25 words. Write them on paper before you go any further.

    Type address to see the address to give people, and help for everything else.

Let other nodes reach you

Your node works fine with outgoing connections alone. To help new nodes join, allow incoming connections on the peer-to-peer port:

$ sudo ufw allow 38880/tcp

Never open port 38881. It's your node's private control port.
