Blockchain with the most commercial application value
blockchain classification:
1 private chain
refers to the blockchain with certain centralized control. Only the general ledger technology of blockchain is used for bookkeeping. It can be a company or an indivial who enjoys the exclusive write permission of the blockchain. This blockchain is not very different from other distributed storage schemes. The participating nodes are only users themselves, and the access and use of data have strict authority management. Due to the existence of centralized control, alliance chain can also be considered as a private chain
features: because the user has the final say, the data inside can not be changed, and there is not much protection for the third party. Generally used for internal audit. The vice president of fire coin technology believes: there are indeed a large number of scenarios in the private chain that can meet the needs of the real world. Limited decentralization makes it easier to reach a consensus, which can make the transaction faster and more efficient, and can provide more controlled functions. Decentralization is the core value of blockchain technology. If the private chain can not make full use of the decentralized trust base constructed by the public chain in practice, its development space will be limited
2public chain
public blockchain is the earliest blockchain and the most widely used one at present. It refers to a completely decentralized blockchain like bitcoin blockchain, which is not controlled by any organization. Any indivial or group in the world can send a transaction, and the transaction can be effectively confirmed by the blockchain, and anyone can participate in the consensus process. Participants in the consensus process maintain database security through cryptography and built-in economic incentives
features: completely open, uncontrolled, rely on encryption technology to ensure security
3 alliance chain
multiple preselected nodes are designated as bookkeepers within a certain group. The generation of each block is jointly determined by all preselected nodes. Other access nodes can participate in the transaction, but not the bookkeeping process (in essence, it's still managed bookkeeping, but it's just distributed bookkeeping. How many preselected nodes are there, How to decide the bookkeeper of each block becomes the main risk point of the blockchain). Anyone else can make limited query through the open API of the blockchain
the nodes participating in the blockchain are selected in advance, and the nodes are likely to have good network connections. Other consensus algorithms without workload proof can be used on such a blockchain. For example, a blockchain has been established among 100 financial institutions, and more than 67 institutions must agree to reach a consensus
Prospect:
the development of blockchain technology has also brought changes in the operation concepts of various instries. New technologies and new concepts have promoted the new development of various instries. This driving force has a huge impact on society and the promotion of economic activities. Many new instrial phenomena will occur one after another, and the public will wait and see, It is expected that this new technology will be used by all instries and benefit all instries better
in the future, it will be applied in all walks of life.
The mechanism of mineral refresh in the original God is 72 hours (3 days) refresh. Four people form a team to dig the mine, and rotate every day. They can also dig all the mines of four people at one time, once every 4 days. But they still have to go to the blacksmith's place to make iron every day. Crystal ore is refreshed every 3 days, white iron ore is refreshed every 2 days, and iron ore is refreshed every 1 day
for the mining mechanism, there is no upper limit (or the upper limit is very high) for mining every day after the public beta, but the weapon experience materials obtained by forging in different ways at the blacksmith every day have a common upper limit of 300000 (equivalent to 120 crystal minerals, except weapons), which means that iron ore, white iron ore and crystal ore share the upper limit
extended data:
it is suggested that three people should take turns to dig one person's world's mine a day; Suppose we dig a on Monday; Dig B on Tuesday; Dig C on Wednesday; Thursday dig a; By analogy, there will be mines every day. Similarly, Xiaobian suggests that the resources with a brush of 48 hours should be mined once every three days
in the game of the original God, the more advanced the ore, the longer the refresh time. For example, for low-grade ore such as iron ore, the refresh rule is once a day; Pyrite, yeposhi and perlite are refreshed every two days, while crystal ores are refreshed every three days
Yesterday I played for 12 hours. I would like to say that it's very important what planet you arrived at. It took almost an hour to repair the plane at the beginning of the game. Because I found the required isotope and repaired the spaceship, I knew that there was material to dig next to the spaceship. The radar even instructed me to dig (sweat) in the mining area 3 minutes away It's easy to collect meteorites from space.
2. Plutonium can replenish life support devices, mining beams and drive fuel. It can save a little more
< 3. Dig the place It's a mine with small proction on the planet. If you dig too much at one time, the patrolmen will attack you. So half of the patrolmen will come to scan you. Stop mining immediately
4. As long as you enter the house, the patrolmen who attack you will retreat. So there are rare mines in need. As long as there is a room nearby, dig carefully. If the patrolmen attack, just run into the house Break the door and rush into the house. The patrolman will go. But only the house that can't use weapons looks useful. For example, the launch mole should not hide from the patrolman
5. The point of the launch mole on the planet. A launch mole can spend money to increase the space of a suit. I currently drive to 26 spaces. I don't know if the suit is full of 30 spaces
6. Abandoned spaceships can be found on the planet If it's better than the existing one, you should pay attention to it before changing. You need to transfer the goods. Also, the abandoned spaceship needs to be repaired. Pay attention before changing the spaceship. Otherwise, you can't fly after changing the spaceship (but your original spaceship will be left nearby after changing the ship. You can change it back first)

8. The NPC spaceships in the space station and the trade station can interact. They can buy or sell, or buy each other's airplanes
9. If you find the place you want to go to, how can the distance and time keep increasing and decreasing? The representative place is on the other side of the planet. So flying out of the atmosphere and moving, you can accurately find
