Palo Alto blockchain is impossible

1. There are still many domestic enterprises that are actually doing blockchain technology, such as fun chain technology, Vientiane blockchain, energy chain group, complex US technology, Xinghe blockchain, Zhigui technology and medical chain group. They are all well-known enterprises with good technology in the instry. Internet giants basically have blockchain sections.

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. AUV public chain adopts the consensus mechanism of activity proof mechanism, all data are open by default, and its own security is generated through its publicity

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

In the application and development of blockchain, it not only faces the technical constraints of the "Impossible Triangle" paradox, but also risks the erosion of national sovereignty. Theoretically speaking, blockchain uses a set of mathematical algorithms based on consensus to establish a trust network between machines, so as to establish credit through technical endorsement rather than centralized credit institutions. It does not need to implement rules artificially, but is controlled by pre-defined technical rules, which is a completely decentralized approach. But it is not

the "Impossible Triangle" paradox in blockchain

in the application and development of blockchain, another factor that affects and erodes national sovereignty is the anarchism and liberalization tendency that the governance of single technology may bring. Blockchain fundamentally subverts the existing legal supervision system, and realizes "autonomy" purely by pre-defined technical rules, which may improve the convenience and efficiency of operation. However, e to the lack of corresponding legal regulations, it is also easy to cause the infringement of national sovereignty, public interests, various organizations and indivial rights and interests. The application of blockchain not only needs to solve technical problems, but also needs to study and solve the connection and integration of cyberspace and real society< br />

8. 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.

9. "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.

10. Xu Mingxing, a blockchain expert, believes that the balance of "decentralization", "scalability" and "security" has always been a problem hindering the large-scale application of blockchain“ Decentralization, scalability and security form an "Impossible Triangle". The pursuit of "security" and "decentralization" can not give attention to "scalability", the pursuit of "security" and "scalability" can not give attention to "decentralization", and the pursuit of "scalability" and "decentralization" can not give attention to "security". From the perspective of scalability, the throughput of mainstream blockchain platforms is still very low. From the security point of view, malicious nodes will destroy the security and stability of the blockchain system, and the constitution of the blockchain based on public key cryptography may be attacked by quantum computing
Xu Mingxing put forward his own solution for scalability and security, from chain to "network", in the way of DAG, by changing the way of data organization, and in the way of concurrent computing, the processing speed of blockchain is greatly improved. At the same time, fragmentation technology can allocate different nodes to different fragments. Each node only needs to verify the transactions in its own fragment, and does not need to verify the transactions outside the fragment, so as to rece the repeated calculation of nodes
