1. In order to make it easier for new people to understand, sister coin will use some metaphors. Although she is not strict, she will understand better
the private key is like your bank card password
the address of bitcoin wallet is like your bank card
as long as you have the bank card and password, anyone can withdraw money from ATM
the address of bitcoin wallet is public, which means that everyone else has your bank card, so your bank card password (private key) becomes very important at this time
once your key is disclosed, others can transfer your bitcoin

2. Bitcoin is an electronic coin proced by open source P2P software. Digital coin is a kind of network virtual asset. Bitcoin is also paraphrased as "bitcoin.". Bitcoin is based on a set of cipher codes and generated by complex algorithms. This rule is not interfered by any indivial or organization and is decentralized; Anyone can download and run the bitcoin client to participate in the proction of bitcoin; Bitcoin uses electronic signature to realize circulation, and checks repeated consumption through P2P distributed network. The generation and consumption of each bitcoin will be recorded through the P2P distributed network and informed to the whole network. There is no possibility of forgery.
3. Each person's wallet has more than one bitcoin address, and each bitcoin address represents a certain number of bitcoins. The bitcoin address is generated through a public key hash (rpiemd + Sha), and the public key is generated by the private key through elliptic curve (ECC). The private key is kept in the bitcoin wallet and should not be disclosed. The public key, together with the bitcoin address, needs to be publicly released through transaction records ring payment transactions, and the effectiveness of payment transactions is verified by the blockchain system.

How are bitcoin addresses and private keys generated? Bitcoin uses elliptic curve algorithm to generate public key and private key, and chooses secp256k1 curve. The generated public key is a 33 byte large number, and the private key is a 32 byte large number. The wallet file wallet.dat directly stores the public key and private key. The bitcoin address we use when receiving and sending bitcoin is obtained after the public key is processed by the algorithm. The specific process is that the public key is first processed by SHA-256 algorithm to get 32 byte hash result, then processed by ripemed algorithm to get 20 byte summary result, and then the address we see is obtained through the character conversion process. This character conversion process is the same as that of the private key. The steps are as follows: first, add the version number to the input content (the summary result of 20 bytes for the public key and the large number of 32 bytes for the private key). After two successive SHA-256 algorithms, take the first 4 bytes of the hash result of the last time as the check code and attach it to the back of the input content, and then encode it with base58, Get the string{ RRRRR}
5. Hello, miner
6. Bitcoin private key is a 256 bit random number generated by SHA-256 algorithm
7. Bitcoin is a hot topic recently. It's a way to make money like lottery, but its appreciation and decline are a bit serious, so I don't mind playing with it.
8. No, there will always be a few different numbers or letters. Because once the phenomenon of repetition occurs, the market may be in chaos. The creator should have thought about what the consequences would be if it happened, so I don't think there will be repetition.
9. Fly to the sky, fly to ariante, and then order camels to the desert.
when you get there, you'll be happy. Go to the desert and knock on the plane map of desert scorpion 29j monster, which is very good.
if you don't think it's easy to knock on the group, you can go to the next layer. There will be more desert marmots.
it's also flat land.
but are you a soldier, If not, it may not be suitable for me. There are many strange pictures in the desert.
it will drop quickly. I think it will be 30 in half a day. I hope you can arrive at 30 as soon as possible.
please accept it·

10. There are mainly two kinds of bitcoin algorithms, which are elliptic curve digital signature algorithm and sha256 hash algorithm
elliptic curve digital signature algorithm is mainly used in the generation process of bitcoin public key and private key, which is the cornerstone of bitcoin system. SHA-256 hash algorithm is mainly used in the workload proof mechanism of bitcoin
the principle of bitcoin generation is the special solution generated by complex operation, and mining is the process of finding the special solution. However, the total number of bitcoin is only 21 million, and with the continuous mining of bitcoin, the more difficult it will be to proce bitcoin, and the cost of acquiring bitcoin may be higher than the price of bitcoin itself
the bitcoin block consists of a block header and the transaction list contained in the block. The size of the block header is 80 bytes, which is composed of 4-byte version number, 32 byte hash value of the previous block, 32 byte Merkle root hash, 4-byte timestamp (current time), 4-byte current difficulty value and 4-byte random number. A block header with a fixed length of 80 bytes is the input string used to prove the workload of bitcoin. Constantly change the random number in the block header, that is, the value of nonce, and do double sha256 operation on the block header after each change, and compare the result value with the target value of the current network. If it is less than the target value, the problem is solved successfully, and the workload is proved to be complete
the essence of bitcoin is actually the unique solution of a set of equations generated by a bunch of complex algorithms. Bitcoin is the first distributed virtual currency in the world, which has no specific distribution center. The network of bitcoin is composed of all users, because there is no center to ensure the security of data.
