Problems solved by technology

[0004] However, in the above-mentioned process of using encrypted currency for transactions, the encrypted currency used by the user must be consistent with the encrypted currency supported by the merchant's terminal in order to make the above-mentioned transaction successful

However, there are thousands of cryptocurrencies currently in use, and each cryptocurrency requires its own digital wallet to be used, which limits the use of cryptocurrencies. At the same time, if the cryptocurrencies used by merchants and users are inconsistent During the transaction, it is impossible to convert between different cryptocurrencies during the transaction, resulting in the inability to carry out the transaction, which limits the flexibility of the use of cryptocurrencies
