Process engine based on blockchain

1. blockchain is a distributed database system participated by nodes. Its characteristics are unchangeable and unforgeable. We can also understand it as an account book system. It is an important concept of bitcoin. A of the complete bitcoin blockchain records every transaction. Through this information, we can find the value of every address at any point in history

blockchain is composed of a series of data blocks generated by cryptographic methods. Each block contains the hash value of the previous block, which is connected to the current block from the original block to form a blockchain.

2. First of all, we must pass the technical audit. Different exchanges have different needs. Most of the processes are relatively simple, but the audit takes a long time. Star Trading in the audit will be very fast, on the currency process do not understand the place there is a special 1v1 service, simple and fast.

3. The procurement process includes information collection, inquiry, price comparison, price negotiation, evaluation, sample request, decision, requisition, order, coordination and communication, expediting, purchase acceptance and payment.

4. Due to the changeable situation of traditional agriculture from proction to transportation and then selling food, farmers can't make much money, and they have to worry about the deterioration and accumulation of vegetables. Dmtc finds a way from the aspect of blockchain, and uses the traceable technology of blockchain to perfectly monitor food, which greatly reces the cost and difficulty.

5. Now the most mature application of blockchain technology is encryption of digital currency, and the issue of digital currency is also called ICO. The process of blockchain ICO: entity establishment,
legal compliance, private placement, community establishment
I learned that there is a unicorn company in Singapore that focuses on blockchain ICO. I hope it can help you.

6. First of all, suppose a person with an empty backpack who has just started the game. On the first morning, it's better to roll the trees first to get enough boards and sticks, and make a wooden manuscript ahead of time. When you see the sun to the west, you're going to start looking for the mine

how to find it<

first press "m" to change the map type to cave

the place with deep color on the map is the mine cave, and the place with light color indicates high altitude.

if you can't see the mine cave, it means there is no cave in a certain depth, then you can try to dig down for a period of time, and generally you can see the mine cave

now what you need to do is to find a small mine - because what you need to do is not to dig, but to find a center for your mine

it would be better if you could get some coal

when you get to the mine cave, you'd better not dig the mine first, which may cause you to fall into a big mine cave

don't act rashly after you find the mine cave, check the whole cave first, and insert the torch. Seal all entrances to the ground

you can make a workbench first

you can also consider making a box, but I don't recommend that unless you have enough wood

you have to wait here for the next day unless you have a bed

on the second day, the first thing is to get out of the cave and build a cabin above your mine cave. It should be fully equipped with boxes, furnaces and fires. It's better to have a bed and a door. It's also necessary to figure out with the mine cave, but it's necessary to put a trap door to prevent monsters from climbing up in the middle of the night

you can do these things in a day

on the third day, you will start mining. First of all, you should take a good wooden manuscript (if you have stone, you can use stone manuscript), torch, food, wooden sword, and bow and arrow

and some stone and wood

of course, if there are stones, first integrate stone manuscript and stone sword< In the early stage, there were two kinds of most important ores:

coal mine and iron mine

iron ore is a necessary tool for making iron tools

if you want to excavate from your mine, you'd better make a door to separate your mine from other mines

the best shape of the excavated mine is 2 * 2 square type

if monsters are found, they should be eliminated in time, especially JJ monsters

remember, don't go into the big mine blindly, and don't go into the underground Canyon or abandoned mine.

7. In what area

8. Many projects belong to the new infrastructure category. Just take the procts and solutions launched by lierda group as an example: (information communication, 5g and other infrastructure network construction) lierda lorawan solution has low power consumption, strong anti-interference, low cost and high capacity; Lilda NB IOT solution has wide signal coverage, strong penetration ability, ultra-low power consumption, ultra-high sensitivity, strong anti-interference and low cost Smart city, municipal pipe network) has a mature underground parking energy-saving lighting system to rece lighting costs, system rability and reliability, save maintenance costs, improve management efficiency Artificial intelligence) Intelligent Hotel solutions meet the personalized needs of customers and make the hotel management service more efficient and orderly

9. Blockchain is a kind of encryption algorithm technology, and ether clown is a kind of game. If they are put together, it is a kind of game based on blockchain technology and secondary development of ether chain. This kind of game belongs to the indivial's own coin issuing process, which is not strict and has the suspicion of pyramid selling

10. Blockchain technology workflow and software analysis: 1 - new data record of sending node is broadcast to the whole network; 2 - receiving data record information of node for inspection; 3 - the received node block of the whole network performs consensus calculation; 4 - the blockchain consensus algorithm is incorporated into the blockchain storage node, and the blockchain continues to extend the blockchain according to the basic verification
