Introduction to Java blockchain
-
the underlying development of blockchain can't be realized with Java
-
as the upper development, you just need to dock according to the given open source interface, and then develop what you need with the language you are good at
-
now there are many blockchain system templates, you can see which development cases

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:

to do the upper development, you only need to dock according to the given open source interface, and then use the language you are good at to develop what you need

The solution to watch water, mirror fog:
< UL >with a few layers of toilet paper or easy to absorb moisture flannelette will watch tightly, put under the bulb baking for about 30 minutes, you can eliminate the water mist inside, but avoid it close to the bulb or directly baking, so as not to cause surface heat deformation
with the surface facing inward and the bottom shell facing outward, put it on the wrist. After a few hours, the water mist in the watch can also be eliminated
if there is silica gel, put the silica gel and the watch with water into a closed container. After a few hours, take out the watch, and the water mist in the watch will disappear
if the watch is seriously affected by water, it is better to send it to the watch shop to wipe oil to eliminate the water in the watch, so as to avoid rust of parts in the watch
note: in order to prolong the service life of the watch, try to avoid fog and water droplets in the waterproof watch. Do not wear the watch when washing face, bathing, swimming and other "hydrophilic" activities. Do not be affected by water vapor and hot vapor. In rainy days, do not be affected by rain
