The Coinbase exchange received a patent making the purchase of crypto safer
Its main idea is encryption of the user's secret key. Existing systems do not provide a solution for maintaining security over private keys - as they believe in Coinbase.
The application temporarily freezes transactions if it becomes necessary to verify their authenticity. The patent explains:
«At any point in time after the master key is loaded, the system can be frozen. The system can be unfrozen using keys from the key ceremony.»
Good solution. With all these hackings, security is really above all.
