Initial blockchain query

1. The blockchain can find the transaction direction and address, but you can't confirm who the address belongs to, which means that it is an anonymous and non lost item. Moreover, bitcoin transaction is irreversible, so it can't be recovered after being stolen

3. Blockchain? Do you mean blockchain technology or blockchain information, or things related to the blockchain instry
1) if it's just "blockchain", the direct network can find a good interpretation of "blockchain network"
2) if it is "blockchain technology", the network also has a good interpretation, and all walks of life are also trying to combine with blockchain technology in new fields. Maybe in the future, blockchain technology will be used correctly instead of being used to deceive people
3) if it is "blockchain information", you can go to all kinds of blockchain media or financial media, and almost every day there are relevant blockchain instry information and news reports. Such as: Babbitt, coin you finance, blocknet, golden, daily, etc
4) if it's "blockchain audio", you can go to Himalaya FM, litchi micro class, qianchat and other platforms. For example, the audio related to "voice of money", "Yu Lingxiong", "Wang Feng" and some other financial media blockchain is also good, with various dry goods and in-depth analysis
therefore, the above four points are all related to blockchain. It depends on your choice.

If you want to see a more complete cvsource where you can download the data of your investment, there is a research report database, which includes other databases besides blockchain, but it seems that it can't be downloaded.
