What does blockchain include

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. Zilliqa is positioned as the bottom public chain, and its core competitiveness is to greatly improve the throughput of TPS (i.e. transaction processing speed) through fragmentation technology. In the latest experiment, the processing capacity of zilliqa test network reaches 2488 TPS, which is more than 100 times of Ethereum's maximum speed of 20 TPS and 355 times of bitcoin! Through fragmentation technology, when the number of nodes in the network is more, the transaction processing speed will be higher. When the number of nodes reaches tens of thousands, the transaction speed will hopefully reach the speed of visa, a centralized organization
zilliqa project's token name is ZIL, which has been circulated and traded on 23 exchanges. Mainstream exchanges such as fire coin and coin an support it, so it is very convenient to participate. ZIL's maximum supply is 21 billion, of which 12.6 billion will be released directly through contracts, and the other 8.4 billion will be released in the form of mining awards within 10 years
the main network of zilliqa will be launched at the end of 2018 or the beginning of 2019, and the mining reward is rich, especially in the early stage. The electric power cost of zilliqa mining is only 1 / 9 of that of Ethereum, so it is more feasible with less energy consumption. In addition, mining can be carried out through GPU graphics card miner, and can simultaneously double dig ZIL and eth, bringing higher benefits for miners

3. At present, blockchain projects can be divided into four categories: currency, platform, application and asset token. Currencies mainly act as the "exchange medium" of blockchain assets, belonging to the general equivalent, similar to the previous gold. Applications in this category include bitcoin, lightcoin, etc. You can learn more about it online

4. 1. Public chain, no official organization and management organization, no central server, participating nodes freely access to the network according to the system rules, not controlled, and work based on consensus mechanism among nodes Subversive: absolutely credible and open) < br > typical case: digital currency represents bitcoin < br > 2. The private chain is built within a group. The operation rules of the system are set according to the requirements of the group, and the modification or read permissions are limited to some extent, while maintaining the authenticity and partial decentralization of the blockchain Typical case: R3 < br > 3. Alliance chain, jointly initiated by several institutions, is between the public chain and the private chain, and has the characteristics of partial decentralization. The read permission on the fast chain in this area may be public or partially public, that is to say, multiple pre selected nodes are designated as bookkeepers internally, and the pre selected nodes compete for bookkeeping permission, Other access nodes can participate in the transaction, but not the accounting process The abilities of the candidates should not be uneven< Br > (relatively credible and open) < br > existing cases: Super ledger < br > example:? In the case of loan diversion, when the user jumps to the other party's website for registration through our link, the docking party can choose to cheat and say that it has not received the user's registration request. However, if we put the user registration behavior into the block, if the docking party wants to receive the user registration behavior, it must pay us at the same time.

5. The classification of Chongqing jinwowo analysis blockchain technology is as follows: according to the participation access mechanism of blockchain, that is, the blockchain account book is not public, we can divide the blockchain into three categories: public chain, private chain and alliance chain.

6. It mainly depends on the functions of the blockchain application app. For example, starting technology is to calculate the development cost of the blockchain according to its functions. If there are many functions and high complexity, the corresponding cost will be relatively high, and the function will be simple, and the price will be very low. Whether it's blockchain wallet, blockchain exchange, blockchain pet game or blockchain points mall, the price is estimated in this way. The main accounting of the development cost is the labor cost and hardware consumption cost, plus some marketing expenses, we can almost determine the price. In one case, the price of the app will be very low, that is, there is a ready-made source code that can meet the needs of customers, and you only need to modify and add some functions to use it.
