== Doing an AMA on r/bitcoin right now ==Today for the first time, anyone can create a
multi-signature shared account on Coinkite!
You can keep any combination of keys to yourself. We cannot access your money, and we’ve made it so you can prove that we can’t.
Use the familiar Coinkite web interface to easily create vouchers, email money, pay for things, transfer money between your accounts and everything else. Multisig accounts are fully integrated into Coinkite’s web interface and our
API for developers.You control the signing rules for your account (M-of-N), and we also use this technology to allow multiple Coinkite users to share access to a common account. Finally all kinds of business accounts are possible (and easy too!) with Bitcoin.
With this new feature, we wanted to be able to offer something to the crypto-currency advocates that are nervous whenever a service holds their precious private keys. Therefore, if you choose, any or all of the private keys for a shared account can be kept secret from Coinkite. We are using BIP32 extended public keys, and every payment address for the account will be unique.
Setup Your First Shared Account- Go to your balances page on Coinkite.com
- Click on button: “+ Create More Accounts”
- Give it a name, and for “Account Type” choose “Shared Account”
- Pick N (number of co-signers total) and M (the minimum number of co-signers to authorize a transaction).
