Upgrading MultiChain

  1. Stop any running nodes: multichain-cli [chain-name] stop  (on Linux use ps -x to check for multichaind processes).
  2. Follow the regular installation instructions, overwriting the older executables.
  3. Restart any nodes required: multichaind [chain-name] -daemon

Next steps

Once MultiChain is installed, you can proceed with the steps in Getting Started or dive straight into the developer guide. You can also install the Explorer for web-based browsing of your blockchain’s activity or the Web Demo for a simple interface for many APIs.

Compiling from sources

If you prefer, you can also compile MultiChain 1.0.x for Ubuntu Linux, Windows or Mac OS X from the source code at Github.
