Direct connection of block chain platform of safe

1.

blockchain includes public blockchain, joint (instry) blockchain and private blockchain. Public chain point-to-point e-cash system: bitcoin, smart contract and decentralized application platform: Ethereum

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. In essence, it is 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 bitcoin network transaction information, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

extended data

according to the different degree of blockchain network centralization, three kinds of blockchains under different application scenarios are differentiated:

1. The blockchain with the whole network open and without user authorization mechanism is called public chain

2. The authorized nodes are allowed to join the network, and the information can be viewed according to the authority. It is often used in the inter agency blockchain, which is called alliance chain or instry chain

3. All the nodes in the network are in the hands of one organization, which is called private chain

alliance chain and private chain are also called licensing chain, and public chain is called non licensing chain

blockchain features

1, decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain

2. Openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent

3. Independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention

4. Safety. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes

5. Anonymity. Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information can be transferred anonymously

1. Jinrong China Financial Instry Co., Ltd.

this is a digital currency trading platform in Hong Kong. At the beginning of trading, it developed on the principle of safeguarding the rights and interests of customers. Similarly, in order to expand trading customers, the company launched the privilege of opening accounts free of charge, and gave customers some concessions in some festivals, This is an important reason why the enterprise takes the first place in the domestic formal blockchain platform

2. Bitfinex

is a digital currency trading platform in Hong Kong, China. It is one of the largest cryptocurrency exchanges in the world. It occupies an important position in the world's cryptocurrency trading and circulation. It also provides the world's most liquid registration policy and plays an important role in the world's trading operations, At present, it occupies the second place in the domestic regular blockchain platform

3. Fire coin network

this is an earlier digital currency trading platform in China, mainly trading bitcoin. As the third instry of domestic regular blockchain platform, it is the trading platform with the largest bitcoin trading volume in China. Many new digital asset trading platforms have been developed under the company, For the future development of the foundation

This is a digital currency trading platform jointly established by some digital currency enthusiasts, and its founder is Zhao CHANGPENG. In fact, this trading platform didn't attract much attention at the beginning. With the continuous operation of the company and the founder's understanding of digital currency, this enterprise has become the top four domestic regular blockchain platforms, which shows the power of this platform

This is one of the most popular digital asset trading platforms in the world. There are many kinds of digital currencies for trading, and their main functions are cash out and derivative trading. They are well-known in the world's exchanges

Blockchain platforms include Ethereum, Asch and other underlying application development platforms

Ethereum, an open source public blockchain platform with smart contract function, provides decentralized Ethereum virtual machine to process point-to-point contract through its special cryptocurrency ether (ETH)

arch, a decentralized application platform based on side chain technology. Asch is designed to lower the threshold of developers, such as using JavaScript as the application programming language and supporting relational database to store transaction data, which is believed to be very attractive to developers and small and medium-sized enterprises

extended data

in 2008, Nakamoto first proposed the concept of blockchain. In the following years, blockchain has become the core component of electronic currency bitcoin: public account book for all transactions

by using peer-to-peer network and distributed timestamp server, the blockchain database can be managed independently. The blockchain invented for bitcoin makes it the first digital currency to solve the problem of repeated consumption. Bitcoin's design is a source of inspiration for other applications

bitcoin is the absolute mainstream of digital currency, and digital currency is in full bloom. Bitcoin, litecoin, dogecoin, dashcoin are common. In addition to currency application, there are various derivative applications, such as Ethereum, Asch and other underlying application development platforms, as well as NXT, SIA, bitstocks, maidsafe, ripple and other instrial applications

4. Triporg travel: it is a blockchain + tourism service platform, which can provide people with train tickets, air tickets and other booking services.

5. Tiger foreign exchange has been committed to using blockchain, big data and other technologies to rece the cost of foreign exchange transactions and make the transactions more transparent and credible

6. Recently, the hottest topic is blockchain. The 24 eldest brothers formed a team to learn blockchain. This event can be regarded as an epic good in the blockchain circle. Starting from the evening of the 25th, bitcoin soared 40% in one day, and then more than n domestic concept coins soared in turn. The whole coin circle was beaten to death. Many aunts in the circle of friends microblog began to study blockchain; On the stock market, the blockchain sector is also very lively, with more than 1000 listed companies claiming to lay out the blockchain field. This shot is really 666. I remember everyone was busy getting rid of blockchain before! It's really forgetful
in a few days, the safe also released the blockchain development plan. It seems that the whole world will be transformed by blockchain. Many people have a kind of blockchain application, which will give the currency transaction and foreign exchange transaction a false identity
blockchain has a natural anti censorship international nature in terms of asset transaction and circulation, and can freely and conveniently circulate without the constraint of traditional concurrent management. On the one hand, there is a great risk, so the safe also said that in China, only RMB can be used for pricing, and anything that may threaten this basis should be prohibited. In a short period of time, it may be difficult for blockchain to achieve anything at the level of foreign exchange transactions. The foreign exchange bureau mentioned the application scenarios of blockchain technology in cross-border trade financing and macro Prudential Management. This direction belongs to the pure technology application direction, which is less related to transactions. At present, it is also the direction that the top priority is to develop, using blockchain technology to optimize the real instry
how to optimize it? Because blockchain has the characteristics of traceability, distributed transparency, tamper proof, etc., for example, in cross-border trade, the data of related parties involved in trade are linked and opened to third parties (such as banks) with permission. In the past, enterprises may need more practical asset mortgage to borrow money from banks, Now, by associating reliable trade data on the blockchain, the bank can know the future cash flow of the enterprise, and can use the operation of the enterprise as asset mortgage to give credit. This will greatly optimize the allocation of assets
another example is the patient information in the hospital. The traditional scenario is that the data of each hospital is independent. Every time you go to a new hospital, you will be asked to do a booklet or a set of examinations. If there is a medical chain open to all hospitals and all information is recorded in this account book, you can avoid a lot of plication and simplify efficiency
it is clear that the priority is to develop blockchain technology to optimize and transform traditional instries, with the focus on the combination with the real economy. I am also very optimistic about this, but in terms of asset trading, the expectation of currency trading and foreign exchange trading should not be too high. After the excitement, it will be calm.

, the world's first electronic wallet cross border remittance service based on block chaining, was launched in Hongkong in June 25th. Hong Kong Alipay AlipayHK users can send remittances to Philippines purse Gcash through block chain technology. p>

ant financial services said that alipayhk cooperated with gcash to become the first e-wallet in the world to use blockchain in the whole link of cross-border remittance, and Standard Chartered Bank was responsible for the day-to-day capital clearing and foreign exchange. Gcash users can consume immediately after they arrive at the account. Cross border remittance can also arrive in real time like domestic transfer, 7 × 24-hour uninterrupted, cost-effective, safe and transparent, it can be said to redefine the "cross-border remittance"

8. The trading principle of sccti contract for difference is similar to that of virtual currency trading. The difference is that when you trade contracts for difference of virtual currency, such as bitcoin, you do not actually hold bitcoin, but trade the price trend of bitcoin,

9. Blockchain is a "big open account book" that uses computer programs to record all transaction information. All those who participate in borrowing know the record information about the big account book, and will not lose "trust" because one of them tampers with the amount or destroys it without permission. In short, the account records are open and transparent, and no one can do anything about it.
