5. Computers with bitcoin clients are called nodes, and all nodes on the Internet constitute a bitcoin network. Whenever a new bitcoin is generated and traded on a node, the node will broadcast to the nearby bitcoin node, and finally the whole network node will record the transaction information
in the bitcoin network, each node with a client installed has a distributed database to manage bitcoin proction, transaction, query account balance records, and update and record the latest records of changes in the bitcoin system
when you want to send 10 bitcoins to your friends. You need two things, one is the bitcoin address, the other is the corresponding private key. Bitcoin addresses are different from bank accounts. You don't need to sign a bunch of documents to apply for them. They are randomly generated, just a string of letters and numbers. The private key is also a similar string, but this is strictly confidential. The bitcoin address is like a transparent piggy bank. Everyone can see what's in it, but only the person with the private key can open it.
after you send the transaction application, the surrounding nodes will check whether your account has 10 bitcoins. If there are, they will agree to the transaction, and broadcast the message to the nearby nodes, which will be transmitted from one to ten, and from ten to 100, Soon the whole network will confirm the transaction information and write it to the block. Your friend will receive 10 bitcoins, and the transaction will be completed.
if you want to send small bitcoins, in theory, digital currency can be cut infinitely. At present, the smallest bitcoin unit is called "Nakamoto Tsung", which is equivalent to 0.00000001 bitcoins.

6. Bitcoin receives payments almost instantaneously. However, there is an average delay of 10 minutes before the network starts adding your transaction to a block to confirm the transaction and that you can use the received bitcoin. Confirmation means that there is a consensus on the Internet that the bitcoin you receive is not used to pay others, so it is recognized as your property. Once your transaction is included in one block, all subsequent blocks will include it, which will greatly consolidate this consensus and rece the risk of transaction cancellation. Each user can determine the time when the transaction is confirmed, but generally speaking, receiving six confirmations is as safe as waiting six months after a credit card transaction
anyone can become a bitcoin miner by running software on specialized hardware. mining software monitors transaction broadcast through P2P network and performs appropriate tasks to process and confirm these transactions. Bitcoin miners can earn transaction fees paid by users to speed up transaction processing and additional bitcoin issued according to fixed formula

new transactions need to be included in a block with mathematical workload proof before they can be confirmed. This kind of proof is hard to generate because it can only be generated by trying billions of calculations per second. Miners need to run these calculations before their blocks are accepted and rewarded. As more people start mining, the difficulty of finding effective blocks will be automatically increased by the network to ensure that the average time to find a block remains at 10 minutes. Therefore, the competition for mining is very fierce, and no indivial miner can control the content contained in the block chain
workload proof is also designed to rely on previous blocks, which forces the time sequence of block chain. This design makes it extremely difficult to cancel previous transactions, because the workload proof of all subsequent blocks needs to be recalculated. When two blocks are found at the same time, the miner will process the first block received, and once the next block is found, it will be transferred to the longest block chain. This ensures that the mining process maintains a global consistency based on processing capacity
bitcoin miners can neither increase their rewards by cheating, nor deal with the fraulent transactions that destroy the bitcoin network, because all bitcoin nodes will reject the blocks containing invalid data that violate the bitcoin protocol rules. Therefore, even if not all bitcoin miners can be trusted, the bitcoin network is still secure

9. 1. The law of multiplication is extended to fractions
the law of integer multiplication is extended to fractions, so that students can feel the subtle relationship between the multiplication of fractions by integers and the addition of fractions with the same denominator

2. Remember the pithy formula well
brackets should be calculated first with brackets, from front to back without brackets, multiplication and division first, and then addition and subtraction

3 Clear the concept
let students understand that the reciprocal of an integer is one of the original fractions, and the reciprocal of a fraction is to exchange the numerator and denominator
