The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system. Bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network will get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer

2. BCC started mining at 20:00 on August 1, and separated from bitcoin's main chain in block 478559. Viabtc, China's mining pool, excavated the first BCC block, and then the next block 478560. Before the separation from the main chain, the data stored in the blockchain and the running software are compatible with all bitcoin nodes. After the separation from the main chain, it begins to execute new code and package large blocks. Thus, a new BCC blockchain is born, and BCC also begins to develop independently.

3. The core advantage of blockchain is decentralization. Through the use of encryption algorithm, tree structure and consensus mechanism, trust relationship is established in decentralized distributed network, data distributed multi node encrypted storage is realized, and an open, transparent, tamperable, verifiable and traceable technology system is created, so that each node can store certificates synchronously and supervise together, It can effectively solve the problems of poor reliability and low security in the centralized mode
the blockchain will generate a unique fixed length string based on the hash algorithm, and store it in the network distributed ledger maintained by all of us, so as to achieve tamperable ownership records and statements. Here's an explanation: blockchain is mainly the underlying technology, and right is the concept of application layer. For the application layer of right in blockchain, it is not only to confirm rights, but also to protect rights (infringement detection / forensics, etc.) and solidify electronic evidence after discovering infringement, which is equivalent to electronic storage based on blockchain technology.

Hello, there are several key points in your question that need special attention. I will elaborate them as follows:

1. in your description & quot; Download a bitcoin wallet software & quot;: This step should be cautious. First of all, your goal is to make bitcoin paper wallets offline. What you want to download is actually [bitcoin offline paper wallets making tool], and these tools are intermingled, and some are even very risky. So what kind of [paper wallets making tool] do you want to choose? It must be an open source (that is, the source code is completely open) proction tool that has been recognized by all of us for many years. After many years, it has experienced the test of time. You can search the Internet for a comparative understanding of this point. It is suggested to search the "secure bitcoin offline paper wallet" to learn more about the comparison and be willing to spend more time

2. to make bitcoin offline paper wallet, it is right to "unplug the network cable". At this time, it is true that the computer you make the paper wallet is completely isolated from the whole Internet, which is the meaning of offline. At this time, you need not worry, because the address and private key of bitcoin wallet are just a certificate, Bitcoin doesn't really need to be put into this wallet (it's totally different from the real wallet, but the network can understand it). The address of bitcoin's wallet is just a record of several public books on the bitcoin blockchain network. Therefore, you can safely use the bitcoin offline paper wallet, The key point is that you actually the private key address of the bitcoin offline paper wallet onto the paper, and ensure that there is no mistake. Save the public key to receive other people's bitcoin transfer. Then, the bitcoin offline paper wallet you generate will be fully recognized by the bitcoin network

3. it is mentioned in your problem description that "I write down the public key and private key with paper, then smash the computer to pieces, and then burn down the host screen with fire" - this is not necessary at all. As long as you unplug the network cable in the process of offline making bitcoin offline paper wallet, no one can peek at your screen, So as long as you choose the secure bitcoin offline paper wallet tool, the wallet you get will be secure. Of course, the most important thing is that you should store the note with the private key of the bitcoin offline paper wallet in a fireproof and waterproof safe. As for the computer you use to generate the bitcoin offline paper wallet, you don't need to break it. At most, you can destroy the hard disk. In the safe bitcoin offline paper wallet tutorial searched above, there are detailed instructions on how to do the subsequent processing

4. finally, you mentioned the operation of transferring money to your offline generated bitcoin paper wallet, which is no different from transferring money to any other bitcoin address. The synchronization process is carried out in the whole bitcoin blockchain network and needs to wait, but this is the confirmation process of the whole network

I hope my answer can help you. It is recommended that you fully study before you operate< br />

5. 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.

6. View the usage of mod, and add it in mod option (main interface).

7. Jinwowo network analysis believes that: blockchain technology redefines the generation mode of credit in the network: in the system, participants do not need to know the background information of other people, nor do they need to rely on the guarantee or guarantee of a third party organization. Blockchain technology ensures that the system records, transmits and stores the activities of value transfer, and the final result must be credible.

8. Distributed key generation (dkg): a group of multi-party members are allowed to generate polynomials together, and each party gets the unbiased random key. The result of dkg is that each party can get a key pair and share a public key. I hope my answer can help you, thank you very much!
