Blockchain technology implementation process
Publish: 2021-04-29 22:17:09
1. From the perspective of data, blockchain is a kind of distributed database or distributed shared general ledger. The "distributed" here is not only reflected in the distributed storage of data, but also reflected in the distributed records of data. From the perspective of effect, blockchain can generate a set of time sequence, tamper proof and trustworthy database
blockchain has four core technologies. The first one is block + chain, which is the most core and basic technology in blockchain. The second core technology is distributed structure. The ingenious design of blockchain structure is to let every node participating in data transaction record and store all data. The third core technology is asymmetric encryption algorithm, and the fourth core technology is script, which can be understood as a programmable smart contract.

2. This concept was proposed in the white paper [1] of Nakamoto Tsung, who created the first block, namely "Genesis block"< On January 3, 2009, the founder of bitcoin, Mr. Nakamoto, left an unchangeable sentence in the genesis block:
"the times 03 / Jan / 2009 Chancellor on brink of second low for banks (on January 3, 2009, the chancellor of the exchequer was on the verge of implementing the second round of bank emergency assistance)."
at that time, the British Chancellor of the exchequer, darling, was forced to consider a second attempt to relieve the banking crisis, which was the headline of the front page article of the times that day
the time stamp service and existence proof of blockchain, the time generated by the first blockchain and the events that happened at that time are permanently preserved
BTCC, a bitcoin company, launched a service "Millennium chain" in 2015, namely blockchain lettering service, which is based on the above principles. Users can use this service to engrave text on the blockchain and save it permanently
bitcoin, Ruitai coin, Laite coin, dogcoin, Ethereum and other digital currencies will use blockchain technology.

3. 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.

4. The application of blockchain technology in life has just started, but the changes it brings are very huge. This kind of change comes from all aspects, and will have an important impact on our ordinary people's lives
"now the college entrance examination is a lifetime, but if we use the form of blockchain, we can record all the learning records and extracurricular activities of a child from the age of six to the college entrance examination. So the examiners of the college entrance examination don't need to pass an exam or an interview to decide the selection of talents. They can decide what kind of talents they want through all their records. "
about the application of blockchain technology, Qin Yi, partner of Deloitte global financial services, said when introcing it to Jinping media
as for blockchain, more explanations in China still stay at the conceptual level, and there is no really large-scale popular application in China, so we have to say that blockchain still keeps a certain distance from the public. In this interview, I believe it can help you have a deeper understanding of blockchain
blockchain is disintermediation
blockchain, and many explanations are decentralization. Different from the general explanation. "It's not decentralization, it's disintermediation," says Qin
because data is distributed in a distributed way, there is a strong security mechanism in it. Qin Yi said: "because no matter which server is serving, the entire data storage is not easy to detect. But most importantly, because of the reliability of the data, we don't need an intermediary to prove who you are, but rely on a record that we can trust each other to promote any transaction in our life
in her opinion, blockchain is actually a database, but when storing data, it has its own characteristics, such as security, integrity, authenticity, non tamperability, etc
for this technology, Qin Yi concluded: such technology will bring earth shaking changes to life
how to embody the commercial value
compared with foreign blockchain technology, domestic blockchain technology is still in a stage of popularization and cognition. What kind of business value will the future blockchain bring us? Looking at the progress abroad, maybe you can see some possibilities
"two weeks ago (on April 20), Bank of Ireland and Deloitte jointly issued a statement. Three months ago, Ireland's International Investment Banking Department asked Deloitte to help design and track the investment behavior of its clients. Strengthen the understanding of customers. In order to meet the regulatory requirements of Europe, they have successfully completed the validation model through the efforts of the past three months. "
a Deloitte executive also said that if this technology can be applied, it will greatly rece the transaction costs of the instry
Deloitte also published a report in 2016, saying that 2016 will be the first year for blockchain to move from laboratory to real life. Bubi (Beijing) Network Technology Co., Ltd. (hereinafter referred to as Bubi) is a leading blockchain technology service provider in China. Since its establishment, Bubi has been focusing on the R & D and innovation of blockchain technology and procts. It has a number of core technologies, and has made substantial innovation in many aspects, forming a number of core technology achievements, such as mathematically proven distributed consensus technology, distributed consensus technology, and so on Fast large-scale account book access technology, multi chain general ledger technology supporting business form expansion, interconnection technology between heterogeneous blockchains, etc. We have developed our own blockchain basic service platform, which has been applied in equity, supply chain, credit and other fields. Bubi has been committed to building an open value circulation network with the core of decentralized (polycentric) trust, so that digital assets can flow freely
with the in-depth development of many companies, the effect of blockchain technology on the life of ordinary people is becoming more and more obvious.

5. Yes, more and more blockchain technologies will be applied in the future, hoping to benefit modern society.
6. The workflow of blockchain technology is analyzed as follows:
1 - the sending node broadcasts new data records to the whole network
2 - the receiving node checks the received data record information
3 - all receiving nodes in the whole network implement consensus algorithm for blocks
4-blocks are formally included in the blockchain for storage after the consensus algorithm process
nodes always regard the longest blockchain as the right one, and continue to verify and extend the chain in turn.
