However, this method has many limitations and is inconvenient in many cases. For example, it needs to generate and save pictures, and complete shooting, printing and picture transmission. It is still difficult to use for quick communication and memory in daily scenes.
[0006] At the same time, the issue of trust between the two parties in online transactions has received widespread attention. In the field of encrypted digital currency, due to the anonymity of the public key address, it is impossible to effectively associate the address with the real identity of the individual. The payer is easy to worry about whether the payee will deny the payment, which will cause some transactions to fail due to trust issues

Embodiment Construction
[0034] Such as figure 1 As shown, in an encrypted digital currency network consisting of a public ledger and n users, n users share the same set of public ledgers (such as Bitcoin’s blockchain, or Block Chain), and store the public ledger in the user’s computer. full or partial copy of . The public ledger has extremely high security, and its security is protected by mechanisms such as Proof-of-work. Such as figure 1In , all transactions of the user will be broadcast to other users in the whole network, and finally entered into the public ledger. The public ledger is used to store and disclose the transaction records of n users. The content of each transaction record includes the transaction number, transaction time, public key addresses of the sender and receiver, the amount of encrypted digital currency sent, transaction fees, and additional information Or script content, etc.; n users have their own different public key addresses and private key addresses, these public ke...

The invention discloses an association and retrieval method and system used for public key addresses and user accounts of crypto-currency. The method includes the following steps that: 1, verified public key addresses are published for users in a crypto-currency network; 2, account registration requests of the users are received, and the public key addresses of the users are received, and corresponding relationships between the user accounts and the public key addresses are established; 3, private key addresses corresponding to the verified public key addresses are utilized to transmit crypto-currency of which the amount is larger than 0 to any other public key addresses, so that the crypto-currency can be adopted as verified transactions, and additional information or script content for setting the verified transactions contains check data; and 4, query requests of other users in the crypto-currency network are received, and the public key addresses of registered users are fed back according to the query requests. With the association and retrieval method and system of the invention adopted, the usability, convenience, safety and reliability of crypto-currency transactions can be greatly improved, and economic losses which are caused by situations in which the public key address of the users are tampered and posed by other people can be avoided.
Description
technical field [0001] The invention belongs to the technical field of encrypted digital currency, and in particular relates to a method for associating and retrieving public key addresses of encrypted digital currency and user accounts and a system thereof. Background technique [0002] In recent years, various encrypted digital currencies (CryptoCurrency) based on global public ledgers (such as blockchain technology), such as Bitcoin, Litecoin, Dogecoin, etc., have begun to be widely used and popular on the Internet. More than ten million dollars and growing. At present, well-known companies and institutions such as Wikipedia, Dell Computer, Newegg, and PayPal support the use of encrypted digital currency payment represented by Bitcoin as a transaction method. [0003] Although there are many social controversies in encrypted digital currencies such as Bitcoin, the technical means used in them have high innovation value. The public ledger used by a typical encrypted digi...
