Crypto exchange Coinbase recently filed for a patent detailing a new system to enable online users to make Bitcoin payments more securely. The patent, filed on August 14, will allow users to make payments directly from their Bitcoin wallet.
The new system will enable users to pay directly in a “key ceremony” which encrypts private user passphrases into a masterkey during checkout to greatly reduce the risk of the keys being stolen. The masterkey serves the function of encrypting private keys and transaction signing, and upon being used the masterkey is deleted.
The system allows for administrators to freeze all processes using what is described as “freeze logic,” presumably in the event that a user reports that they are being hacked or their identity is being assumed.
