Onchian blockchain

1.

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies

blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a bitcoin network transaction, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

some areas where blockchain can be used can be as follows:

& ᦇ 9642; Smart contract; Securities trading; E-commerce; Internet of things; Social communication; File storage; Proof of existence; Authentication

&9642; Equity crowdfunding

we can compare the development of blockchain with the development of the Internet itself. In the future, something called finance Internet will be formed on the Internet. This thing is based on blockchain, and its precursor is bitcoin, that is, traditional finance starts from private chain and instry chain (LAN), bitcoin series starts from public chain (WAN), They all express the same concept - digital asset, and finally converge to an intermediate equilibrium point

The evolution mode of

blockchain is as follows:

& 9642; Blockchain 1.0 digital currency; Blockchain 2.0 digital assets and smart contracts; Blockchain 3.0: implementation of distributed applications in various instries

Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

if such technology wants to be put into application, the biggest problem is the "Impossible Triangle problem"

that is, scalability, decentralization and security cannot be achieved at the same time, and only two of them can be achieved

most of the existing public chain projects in the market are difficult to put into use on a large scale

3. 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.

4. At present, the centralized exchanges are more popular, such as currency security, gate and fire currency, and gate is more convenient to access gold. However, decentralized trading is a trend in the future. Now, in the area of decentralized trading, the Luyin agreement is doing better in China.

5. tolerable. The police have Internet experts. Besides, if you are cheated, you can only call the police and ask for their help. Personal point of view, for reference only.

In short, blockchain is a distributed bank accounting system, a trust network without central institutions, and a distributed database. Because of its distributed storage, decentralization and other characteristics, it can effectively prevent tampering and repudiation, and has incomparable system stability compared with the traditional mode

based on the above characteristics, blockchain technology has been combined with the financial instry, and has been applied on a large scale, and has made remarkable achievements. In August 2016, we, together with onchain, jointly launched an open blockchain alliance "falian" based on Microsoft trusted cloud technology and open platform, and Microsoft comprehensive technology and open platform

based on the technical support of "French chain", we have reached a cooperation with Alibaba mailbox and launched the world's first e-mail deposit proct based on blockchain technology. With the growth of the Internet environment, the demand for e-Cert will also grow, and our "legal chain" will play a greater role

Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies

in a narrow sense, blockchain is a kind of chained data structure composed of data blocks connected in sequence according to the time sequence, and it can not be tampered with and forged by cryptography

it is an important feature of electronic contract system, which can not be tampered with and forged, and effectively improve the security of electronic contract

in 2016, we, together with Microsoft (China) and onchain, jointly launched the establishment of "French chain", which deeply integrates electronic contract and blockchain technology. Digital fingerprint information such as signing time, signing subject and file hash value of electronic contract will be broadcast to the respective nodes of all members of "French chain". Once all the information is stored, no party can tamper with it, so as to realize the anti tampering of electronic evidence and ensure its objective authenticity

9. Yunxiang is a national team. It has a lot of cooperation with banks. The state does not allow it to issue money, but can only do technology chain
all business scenarios can operate the blockchain, which is the database. The token financial system needs to wait for the opening of national policies.
