1. The digital signature of bitcoin is an anti-counterfeiting string generated only by the transferor of bitcoin transfer. By verifying the digital string, on the one hand, it proves that the transaction is initiated by the transferor, on the other hand, it proves that the transaction information has not been changed in the transmission
digital signature shortens transaction information to a fixed length string through digital digest technology. For example, when Niuniu initiates a bitcoin transfer, it needs to first digest the transaction into a string, and then encrypt the digest with its own private key to form a digital signature. After the completion, Niuniu needs to broadcast the original (transaction information) and digital signature to the miner, and the miner uses Niuniu's public key for verification. If the verification is successful, it means that the transaction is indeed sent by Niuniu, and the information has not been changed
at the same time, the private key encrypted by digital signature is inconsistent with the public key decrypted by digital signature, so asymmetric encryption technology is adopted. It looks so complicated. In fact, you only need to input the private key to complete the transfer instantly!

2. This depends on what your bookkeeping base currency is. If it is RMB, you can directly
borrow Bank Deposits - US dollars
borrow Bank Deposits - personal currency
expenses are calculated in RMB. For example, if the entry above is 100 personal currency, it is to borrow 100 US dollars from 100 personal currency, but this US dollar is not a real 100 US dollars, but a US dollar worth 100 RMB....
