Can't the blockchain be broken through

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 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

2. At present, there is no clear legal basis to prove the legitimacy of blockchain investment in China, and there is no law to prohibit the development of blockchain. However, blockchain investment also has great legal risks under the appearance of high income. Because blockchain is only a technology and method, there is no saying whether it is a hoax or not. However, different blockchain investments may be a hoax and more likely to involve crimes according to their forms
first of all, e to its lack of supervision, its circulation and trading forms are mostly similar to the issuance and listing of securities, and there is the behavior of setting up an exchange for trading. Its trading process and trading results are not transparent, and it is difficult to regulate when encountering problems. Moreover, its price formation mechanism is not transparent, and the trading price fluctuates greatly, which is easy to make investors suffer huge losses
secondly, it is not recognized by the central bank and can not be used as currency in China. Once it is subject to policy supervision, it is likely to encounter the risk that no one will take over the offer and the price will plummet, and the property law does not clearly protect the corresponding provisions of digital currency. Therefore, it is very dangerous to speculate on the blockchain, which is equivalent to streaking in the cold winter
finally, although blockchain is not illegal, it can not be ruled out that it is used by a small number of fraudsters and illegal fund raisers as a tool for crime and money laundering
therefore, it is recommended to carefully participate in blockchain investment to avoid irreparable losses.

Because the blockchain technology is not mature at this stage, and the infrastructure is not perfect, many applications are limited, and the overall application is still in a very early stage

First of all, the main function of blockchain is to store information. Any information that needs to be saved can be written to or read from the blockchain, so it is a database. Secondly, anyone can set up a server and join the blockchain network to become a node. In the world of blockchain, there is no central node (decentralization). Every node is equal and keeps the whole database. You can write / read data to any node, because all nodes will be synchronized in the end to ensure the consistency of the blockchain

4. Based on the current consensus of the instry, there are two milestone practices in the development of blockchain. One is bitcoin, which is called the first generation blockchain, and the other is Ethereum, which is called the second generation blockchain. The key breakthrough lies in the realization of smart contract. Blockchain is still in the early stage of development. Now, blockchain policies in various regions are released in competition, and blockchain applications in various regions are constantly landing, Changsha high tech Zone has officially launched a blockchain project, which is called SMIC blockchain service platform. It is a government enterprise service platform. It cooperates with Bank of Changsha, Dean justice, etc., and now it is the stage of collecting enterprises on the chain.

5. Safety still needs to understand the platform carefully, including the risk control measures of the platform. As long as you want to choose a bank deposit, performance insurance, but this is for investment.

6. Blockchain is the underlying technology of bitcoin. You can think of blockchain as a distributed database for storing bitcoin transactions. In the whole network, each node will have a complete blockchain

blockchain technology has realized the key characteristics of tamper proof, decentralization, anonymity, security and reliability. Now more and more instries choose to use blockchain technology. For example, NASDAQ has adopted blockchain technology to realize LINQ, a private equity trading platform. It is more secure, and the transactions stored in the blockchain can not be tampered with, that is to say, once written, it is impossible to be modified. In the future, the application of blockchain will be very wide, and all aspects can be applied to blockchain technology. For example, in the future, schools can store the electronic version of Graation Certificate in the blockchain, which will not be tampered with. Employers can check the authenticity of students' graation certificate by querying the information in the blockchain.

The current development stage of blockchain Technology: financial value period, credit value period and governance value period. Among them, blockchain 3.0 and 4.0 are developing rapidly. It is predicted that there will be a wave of great changes in blockchain technology

ecology makes the main chain and the side chain

ecol ecology makes the team deal with the difficulties faced by the side chain. Through data isolation and cross chain audit, the business data confidentiality and security of the side chain can be guaranteed, and the balance between data transparency and business confidentiality can be solved

and support multi side chain, main side chain communication, asset transfer, both integration and division of labor, both security and convenience. The main chain is mainly responsible for security and consensus. The side chain will provide smart contracts, token issuance, asset trading, cross chain interoperability, and the structure of the main and side chains. Through slimming and pruning technology, it can effectively prevent block swelling, garbage accumulation, and shorten synchronization time. To clear the obstacles for the implementation of high concurrency and lightning network

ecol ecol makes it possible to connect different blockchains through side chain technology, which is the key to solve the problem of slow transmission speed and low efficiency in expanding the external structure of blockchain. In short, the side chain is like a channel, connecting different blockchains together to realize the expansion of blockchain. In the long run, ecolink will graally build a high-speed value Internet belonging to the side chain in the case of developing, applying and proposing solutions

9. First, the POS + pod hybrid consensus mechanism of the exclusive game community greatly improves the efficiency and consistency of the public chain network
Second, community autonomy. All decisions are made by community members. Under the hybrid consensus mechanism, both POS krypton players and pod technology players have higher yield and discourse power, which effectively avoids the impact of centralized computing power and financial resources on the whole game ecology, and thus reces the risk of bifurcation. If a node wants to propose a bifurcation for a certain protocol or standard, all nodes need to participate in the voting. If the pod + POS weighted value of the voting result exceeds 50%, the system defaults to the chain with high weighted value as the effective chain, and all nodes will migrate to the new chain mining at the time agreed in the voting result
thirdly, because game players have requirements for the performance and bandwidth of hardware devices, vs public chain sets the node players involved in accounting into two categories: full node and light node. Players can manually switch between full node and light node. Generally, light node mode is adopted in the process of the game to provide more hardware support for the game, and full node mode is started after the end of the game and ring the hang up period
fourthly, all the transaction rights in the game come from the players. Only after the players are authorized by the exclusive secret key, the game assets can be circulated. At the same time, all transaction data are encrypted by ECC (elliptic encryption algorithm), which is a modern cryptography technology, to ensure the information security of blockchain
fifthly, as a vertical public chain in the game field, vs will first complete the overall solution of decentralized game proction, virtual asset distribution and token economy operation. It includes game engine, developer environment, standard SDK, etc., which reces the difficulty and threshold for game developers to enter blockchain game development from various environments, greatly reces the workload and cost of game development team, and also makes vs public chain highly scalable.

10. "Impossible Triangle of blockchain" means that in a distributed computer system, consistency, availability and partition fault tolerance cannot be guaranteed to be satisfied at the same time, and at most two of them can be satisfied at the same time; System designers need to make choices according to different needs

in the current HNB application scenario and economic model, efficiency should be considered first, and it needs to support larger concurrent transactions and high performance. At the same time, as a system around payment as the core, in the premise of ensuring low delay, we need to avoid double spending problem, so safe and reliable is also crucial. Based on the above analysis, HNB proposes a dpos + algorand algorithm, which elects the consensus group through dpos, and then algorand generates the blockchain

the main advantages of the consensus algorithm based on this combination are as follows: first, the nodes selected by the dpos of identity attribute fully consider the distribution of interests and fairness, and avoid the evil situation of a single group. 2、 In addition, dpos is more stable and relatively high-performance than algorand, which is used to select ordinary users randomly. 3、 Bookkeepers are completely random and secretive, and can't generate specific attacks on them. 4、 On the premise of ensuring the security, we don't do meaningless calculation and save computing resources. 5、 The probability of single bookkeeper bifurcating is close to 0, and the fault tolerance rate is high

in this way, the "Impossible Triangle of blockchain" can also be effectively solved, creating a fully guaranteed community environment for HNB users.
