Abstract
The present disclosure generally relates to the field of digital currency, more particularly, cryptocurrency and secure payment systems using Public-key cryptography. The new cryptocurrency system utilizes digitally locked coins that can be owned and exchanged anonymously without the need for any owner account. Coin owners exchange coins by sending the digital keys of the coins, and recipients use the received digital keys to change the digital locks of the received coins. The digitally locked coins are tracked in a public book that is maintained centrally or distributively by one or more bookkeepers. The new cryptocurrency system is efficient and provides fast, anonymous, and secure transactions.
