It is generally believed that a bitcoin transaction will be succ

1. At present, the main transaction modes in bitcoin market are as follows:
1. Legal currency transaction: that is to buy, sell or trade digital assets through legal currency. For example: bitcoin now quote 6 in case, then whether it is credit card or Alipay WeChat, anyway, buying money directly is the legal tender transaction.
2. Currency currency transaction: mainly for transactions between virtual currency and virtual currency, one of which is used as the pricing unit to purchase other currencies. Its trading rules are also based on price priority and time priority
3. Leverage Trading: it is to invest several times of the original amount with small amount of funds. In order to obtain the relative investment object volatility multiple yield, or loss. As the increase or decrease of margin does not move in proportion to the fluctuation of underlying assets, the risk is very high
4. Contract trading: contract trading is the general term for the futures contract trading of the 796 exchange in comparison with the special currency. In June 2013, 796 exchange took the lead in developing bitcoin weekly delivery standard Futures - t + 0 two-way trading virtual commodity barter contract (contract trading) in bitcoin instry

2. Ah, the transaction logic of bitcoin is generally based on a principle of a blockchain, and then as we say, it is a buy and buy out of content

3. The first transaction of bitcoin was not pizza, but took place in the independent forum of bitcoin. In 2009, a person exchanged $5.02 for 5050 bitcoins, and the unit price was the electricity cost of one bitcoin.

Transaction mode of bitcoin

bitcoin is e-cash similar to e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free

a bitcoin address is a string of about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it doesn't need to exchange information online, so it can be offline. More than 2 bitcoin addresses are available. Figuratively speaking, there are about two grains of sand in the world. If there is an earth in each grain of sand, then the total number of bitcoin addresses far exceeds the number of all the sand on all these "earths"

the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which records how much bitcoin you have on it. You can generate bitcoin address at will to store bitcoin. When each bitcoin address is generated, a corresponding private key of the address will be generated. This private key proves that you have ownership of the bitcoin at that address. We can simply understand the bitcoin address as the bank card number, and the private key of the address as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep your address and private key when using bitcoin wallet

after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed. Bitcoin P2P stores all transaction history in a "blockchain.". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. Blockchain is actually a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history. Nakamoto predicts that when the amount of data increases, users hope that not all the data will be stored in their own nodes. In order to achieve this goal, he uses the hash function mechanism. In this way, the client will be able to automatically eliminate those parts that it will never use, such as some very early bitcoin transactions

5. No, the transaction that belongs to you, that is, your utxo will be saved to your bitcoin wallet file, and each payment will be found from your wallet database. If you lose the contents of your wallet, you can use your key information to access the service node to retrieve your utxo. If you lose the key, don't worry.

The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed< br /> 
when we submit a transaction, under normal circumstances, the transaction will eventually be put into a certain block by miners. At this time, we can say that the transaction has obtained 0 confirmations. When there is another blockchain to this exchange in the block, that is, when this exchange in the block is the parent block, we say that this transaction has been confirmed, and so on. How many confirmations a transaction has obtained is just how many blocks the exchange links behind the block.

7. In theory, at the last moment of bolt tightening, the stress on the bolt reaches the allowable strength of the bolt (determined by the strength level of the bolt (e.g. grade 8.8, when the tensile stress of the bolt is 800N / mm2). The force on the bolt can be calculated according to the diameter of the bolt. According to the diameter of the bolt (take the pitch diameter of the thread) and the pitch of the bolt, the inclined angle of the bolt is obtained; According to the static friction coefficient between the pressure (i.e. the force acting on the bolt) and the material, the thrust can be obtained. The thrust multiplied by half of the pitch diameter of the thread should be equal to the torque of tightening the bolt. The moment divided by the arm length from the point of action of the force to the center of the bolt is the force required on the wrench. Of course, this is not the preload of the bolt.
