Title: Multiple Signature Bitcoin Account?
Post by: shamaniotastook on February 26, 2013, 05:41:28 AM
This is something that I am asking to hopefully save some time in unnecessary research and development. I think BitCoin does offer a mechanism to make it so that more than one signature is required to transfer BTC from an account? Please advise if you're aware of such a solution, or the merits/uses of such.

This has multiple use cases (some are explained at http://bitcoin.stackexchange.com/questions/3718/what-are-multi-signature-transactions), but software support is still in its infancy (http://bitcoin.stackexchange.com/questions/3557/how-does-one-make-multisignature-transactions-with-the-bitcoin-client).
