1. The private key is your bank card password, and the address is your bank account number, but the private key is more important. With the private key, you can push out the address. If you forget the private key, you will lose everything. The signature is personalization, plus a verification procere. The wallet is a small ATM, which can be sent after the update. If the wallet file is saved, it will be OK. BTC China is OK, and you can buy money.
2. 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!

3. The digital signature in bitcoin is generated by the initiator in the transaction. In order to ensure that this transaction is initiated by this person, and the data is not tampered with ring transmission. Digital signature is simply a complete transaction information, compressed into a fixed format string by digital digest technology, and then generated a private key by asymmetric encryption technology. The complete transaction information and digital signature are sent to the miner. The miner decrypts the digital signature with the public key of the transaction initiator. If the decryption is successful, the transaction data will be written into the block.

6. The ID of bitcoin transaction you said should be the address of bitcoin wallet. If the address of bitcoin wallet is wrong, you can't send out bitcoin, it will prompt you to go wrong. Another is that bitcoin transactions will be broadcast all over the network. The records of bitcoin transactions can be queried by anyone and cannot be modified
a bitcoin address is like a physical address or an e-mail address. This is the only information you need to provide when someone pays you bitcoin. An important difference, however, is that each address should only be used for a single transaction
block chain is a public record of bitcoin transactions in chronological order. The block chain is shared by all bitcoin users. It is used to verify the permanence of bitcoin transactions and prevent double consumption.

7. This kind of thing also believe ah, recently the RMB appreciation, you know, also replace the RMB nonsense are made up, who told you, scold him a liar, let him go
8. Blockchain is a technology and bitcoin is a proct
the proct has been finalized, you can only choose to accept or not, but the technology can be applied to all walks of life
