Thin wallet / private key remotely

Question

I have a bunch of RPi nodes that I want to communicate with Multichain. Since it's not possible to compile multichain for RPi, I will have to offload the wallets to a remote machine and set up the RPi's to communicate via the RPC - not an issue.

One thing I am wondering though is if it is possible to still store the private keys on the RPi, essentially turning the remote wallets into thin wallets and signing the transactions locally, so the remote wallets do not need the private keys.

Answer 1

Absolutely, this is not a problem. Please get started by reading / working through this tutorial:

http://www.multichain.com/developers/external-key-management/

MultiChain's transaction format and cryptography is bitcoin-compatible, so you can use a bitcoin library on the Raspberry Pi to sign the transactions.

Thank you, this is exactly what I was looking for! I must have missed that in the docs somehow... great, I can continue!
