Net bitcoin RPC

1. Do you want to learn blockchain development technology or just want to know what blockchain is? If it is the former, you can look at the code of other blockchain projects and learn about it first. If it is the latter, we can pay attention to some good blockchain we media. Blockchain is an emerging instry. There is no ready-made training course. It depends on self exploration and understanding.

2. The development is OK. I think it is more stable than other platforms.

3.

In addition to the complete implementation of bitcoin's core protocol, bitcoin node software also includes an optional but important function mole -- Wallet:

you can regard the wallet as a safe to store all your keys and addresses, and also encapsulate many technical concepts and details of bitcoin, So that it can be understood and accepted by people other than geeks. Therefore, bitcoin enables node wallet by default. If you want to disable the wallet function, for example, you can set the disablewallet option in the configuration file:

disablewallet = 1

the wallet mole will track all address related transactions managed by it, so it can update the balance information of the wallet in time. This function is very important because there is no concept of account in bitcoin. Bitcoin is e-cash scattered among transactions. If there is no wallet to help track transactions related to our address, it is difficult to figure out how many bitcoins we hold in total

Many RPC calls provided by

nodes are implemented by wallet mole. For example, when we call the getnewaddress command, the wallet mole generates the key and address and automatically adds them to the wallet, so its related transactions will automatically affect the balance of the wallet. Similarly, when we call getbalance, the wallet mole will collect the bitcoin on all addresses and return the total amount

9. Digital currency refers to the digitization of money. Digitization doesn't mean scanning. This is just like digital signature. Digital signature does not mean scanning your signature into a digital image, or using the touchpad to obtain the signature, let alone your signature. Digital currency is often mistaken for virtual currency. But virtual currency refers to non real currency. For example, when you play "Three Kingdoms" (game) or "grand Voyage", you have money, and that money is virtual. Of course, the virtual money will also have its real value. For example, if you buy her / his account from another player, you can get all the virtual assets of that player, and then it will be much easier for you to continue playing. Virtual money is not necessarily digital. For example, children play games with pebbles as virtual currency.
