Oneapp blockchain

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

2. Blockchain app
what kind of app? Exchanges
wallets
cloud mining machines
or blockchain pets
there are many kinds of them. Please see the following pictures for details

3. Chainstore blockchain application store is a professional application store that integrates all the mainstream applications of blockchain and coin circle. It integrates exchanges, wallets, quotation software, tool software, blockchain information, blockchain games, instry applications, etc.

4. You can download a "coin listening" app, a live answer software. They will share 12 questions every day, and the questions in it are knowledge related to blockchain. A must for beginners! I'm also learning. Let's refuel together~

5. Ptchat (chain language) belongs to blockchain social software. With the help of public chain 3.0 technology, good decentralization and privacy protection performance, it can really meet the privacy needs of users for encrypted transmission of chat content. You can download it.

6. There are also many apps related to blockchain, such as exchanges, wallets, games, etc. What do you need to know? Only one blockchain app can't provide much information. Relevant blockchain information can be found in cryptography.

7. Blockchain cashier box refers to a kind of cashier equipment upgraded from the traditional cashier equipment (POS machine, code scanning gun, two-dimensional code, etc.) system by adding blockchain technology. It is also a landing application of blockchain in the payment instry, which transforms the concept into reality. The encryption technology of blockchain makes the personal consumption data obtained wantonly by the cashier device encrypted. In the past, when consumers paid, their personal account number, consumption amount and consumption area were exposed to the background of businesses, equipment and machines, and intermediate information processing institutions. These data in a certain period of time after statistics for big data analysis, then the consumer's personal fuzzy information can appear on the table of some institutions through a variety of gray channels. For example, telephone promotion, credit card installment, insurance, and even debt collection. With the intervention of blockchain and data encryption, this grey instry has been greatly curbed. The consumption data of consumers should belong to indivials. I want to give it to businesses, I want to get a discount, and so on, I will open it. If I don't want to, then businesses can't bother me. This is the significance of blockchain cash box.

Neo, China's largest cryptocurrency, is growing rapidly, despite government regulations and rumours of restrictions on mining. At present, the currency ranks 12th in the world, with a market value of more than US $12 billion. Indeed, it's growing very fast: now it's $112 per currency, but half a year ago it was only $1

Bitcoin is the first cryptocurrency in the world. It is no accident that it appeared in 2009 after the world financial crisis. At that time, the financial management departments of many countries, including the United States and China, injected a lot of liquidity into their economies in order to overcome the crisis as soon as possible. These measures are called differently: quantitative easing in the United States and anti crisis measures in China. But in any case, its essence is to issue a large amount of money, which leads to its devaluation

just at this time, the idea of uncontrolled payment system and settlement unit with the same name came out of the founder (or team) of bitcoin. Because of this, bitcoin can be accepted by people and graally become popular. Despite the hype of bitcoin's current boom, the reason why we liked bitcoin at the beginning was its liberalization idea and blockchain technology to ensure its operation

blockchain, in short, is a database accessible to all Internet users. Here is a record of who allocated bitcoin to whom. These records are encrypted and recorded point-to-point, so it is almost impossible for this kind of database to fake

9. Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system
blockchain is the underlying technology of bitcoin, like a database ledger, recording all transaction records. Because of its safety and convenience, this technology has graally attracted the attention of the banking and financial instry.
