Title: Spending bitcoins from a M of N private key?
Post by: knight22 on May 25, 2014, 05:44:45 PM
If I create a split private key with https://www.bitaddress.org, where am I supposed to use those keys in order to spend the bitcoins?

The m of n on bitaddress is not a bitcoin multisig transaction so as far as the network is concerned there is only a single keypair and corresponding address.  BitAddress is just breaking up this key to provide redundancy when storing it offline. You combine the key parts to form the full key before using it on the network.

To combine the split keys you need to use bitaddress (there is a combine option) which will produce the full private key.  You would then import that into a wallet and use it like any other keypair.

Thanks for your quick reply. Can you point me where I can use a real multsig transaction?
