Development of bitjava currency

1.

blockchain projects require high efficiency, so most of the core source code development is using C / C + +. However, if you are doing a blockchain project, unless you need to make a lot of adjustments to the source code, you may not choose to use Java. For general DAPP applications, java development should also be a good choice. For example, in the case of Ethereum blockchain, there is a web3j class library for Java, which is very convenient; bitcoin has bitcoin J class library, which is also easy to use. It still depends on the level of application, what to do, and the situation of the team

share two Java blockchain tutorials:

2. On January 3, 2009, the author of the white paper, Nakamoto Tsung, was located on a small server in Helsinki, Finland. He personally created the first block, the creation block of bitcoin, and won the first 50 bitcoins automatically generated by the system. The first bitcoin came out

bitcoin is a virtual encrypted digital currency in the form of P2P, and point-to-point transmission means a decentralized payment system.

3. Who told you that bitcoin will soon be divided up? Besides, blockchain bitcoin is not a single value function. If you participate in it, you can also save distributed account books. This is not measured by value, and it will make the blockchain era in the future. If you have the strength, I suggest you participate in the proct of the era. Ha ha

4. The 21 million bitcoins are artificially set in the source code. One of the parameters can change the upper limit, but most nodes must be changed uniformly, so it is impossible to change them.

5. BCC perfectly solves the problem of developer centralization left over by BTC history. At present, BCC has four development groups: bitcoin XT, bitcoin classic, bitcoin unlimited and bitcoin ABC. These four development teams are both supporters of big blocks and competitors of bitcoin expansion scheme. At present, they have developed BCC compatible versions. In the future, BCC will have more development teams to participate in the competition.

6. In what area

7. This is not very clear. You can check it on the Internet or on the btc123 navigation. I haven't heard of it in the currency circle for such a long time. I don't know the technology and don't pay much attention to it

bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system.

8. Nakamoto Tsui (a mysterious figure)

9. At present, the actual defender is bitcoin foundation. Basically, chief scientist Gavin Andresen is in power, and his position is similar to Linus and Linux.

10. It depends on what type of mine you work in:
1. Excavators are not allowed to be used in high gas and double outburst mines (unless they are explosion-proof). These mines can only use excavators on the ground, which is no different from other construction sites
2. If the excavator is used in an ordinary mine, there are more risks: the most important risk is hydrogeology, followed by the risk of roof rock falling (collapse), and the risk of st
3. If it is open-pit coal mine, the biggest risk is st, which will lead to silicosis
it is suggested to choose regular large state-owned mines, and the safety facilities and security of indivial and township small coal mines are not in place.
