## Custom Add-ons for your Sovran Pro

Add-ons are extra features you can have installed before your Sovran Pro is shipped to you or you can install them yourself. 

1. Since Sovran_SystemsOS runs Bitcoin Knots by default as opposed to Bitcion Core, you can customize your Sovran Pro's Bitcoin node to run Bitcoin Core.

2. BIP-110 keeps Bitcoin more efficient as Peer to Peer Cash and you can run it along side your Bitocoin node.
