Technical deficiencies of blockchain

Publish: 2021-04-20 15:27:23
1. "blockchain is a shared distributed database technology, and its advantages are mainly manifested in three aspects: distributed decentralization, no need to trust the system, tamper proof and encryption security."
first, the meaning of blockchain technology
blockchain technology is a kind of technology that uses decentralized consensus mechanism to maintain a complete, distributed and tamper proof ledger database. It can enable the participants in the blockchain to realize a unified ledger system without establishing a trust relationship. The block is a public account book, which needs multi-point maintenance; Chain is covered with timestamps, which can not be forged. Blockchain is essentially a technology that focuses on security and credibility rather than efficiency
at present, there is a database behind all systems, that is, a large account book. So it's very important who keeps this account book. Now, whose system is who will keep accounts, and the bank accounts are the records of each bank, and Alipay's account is Ali. But now in the blockchain system, everyone in the system can have the opportunity to participate in bookkeeping. If there are new transaction data changes in a certain period of time, everyone in the system can make bookkeeping. The system will judge the fastest and best bookkeeper in this period, write the recorded content into the account book, and send the content of the account book to all other people in the system for backup. In this way, everyone in the system has a complete account book
as a result, the data becomes very secure. Tamperers need to modify more than half of the system node data at the same time to truly tamper with the data. The cost of such tampering is so high that it is almost impossible. For example, bitcoin has been running for more than seven years, and countless hackers around the world have tried to attack bitcoin, but so far there have been no trading errors. It can be considered that bitcoin blockchain has been proved to be a safe and reliable system. Therefore, it can be considered that blockchain technology is a way for the whole people to participate in bookkeeping, and what it will bring is the innovation of bookkeeping.
2. At present, there are still many problems in the practical application of blockchain technology, such as low performance, less transaction frequency per unit time, lack of technology application ecological environment, lack of relevant application cases and fraud in the name of blockchain.
3. The first factor is to promote on-demand trading and rece unnecessary trading volume. In the node, the positive n-order matrix is a natural cabinet for data storage. Its output uniqueness perfectly solves the integrity of sealed data. The use of pointer greatly improves the feasibility of this scheme. Shortening the verification time can increase the transaction frequency. Chainnova is a blockchain company. I feel it's very good.
4. "One of the important reasons why the working theory of smart contracts has not been realized is the lack of digital systems and technologies that can support programmable contracts. The emergence of blockchain technology solves this problem. It can not only support programmable contracts, but also has the advantages of decentralization, non tampering, transparent and traceable process, so it is naturally suitable for smart contracts. Therefore, it can also be said that smart contract is one of the characteristics of blockchain technology "
the smart contract based on blockchain technology can not only give play to the advantages of smart contract in cost efficiency, but also avoid the interference of malicious behavior on the normal execution of the contract. The smart contract is written into the blockchain in digital form, and the characteristics of blockchain technology ensure that the whole process of storage, reading and execution is transparent, traceable and tamperable. At the same time, a set of state machine system is constructed by the consensus algorithm of the blockchain, so that the intelligent contract can run efficiently.
5. The mines in Outland should be the most valuable, but it's hard to mine, and the mines in pandaliya are also good
under the ideal situation of big bird mount + no one grabs the mines with you + opposing camp doesn't kill you + familiar with the mines, more than 1000g per hour
under normal circumstances, e to various interference factors, 500g per hour is good, minus 200g per hour, the actual income is 300g per hour, If you are engaged in manual mining, you should also consider the fatigue factor. The more mining, the lower the efficiency. It is not recommended to use this lowest level method of earning money. Just like the wage earners in big cities, they can barely earn a living (point card money), but they have no future

8. Jinwowo thinks that if blockchain technology wants to be widely used in China, the first problems to be solved are as follows:
1 - blockchain is too large
2 - blockchain data confirmation time
3 - deal with the issue of transaction frequency
4 - the development of blockchain technology is restricted by the current system
5 - the integration cost of blockchain technology and existing systems is relatively high
9. According to the analysis of jinwowo network technology, although many of the infrastructure and applications of blockchain are not perfect and mature, as long as they reach the critical point required by a certain application, there will be suitable projects running out, successfully detonating the market and creating commercial value. Of course, they will first reap rich returns, rather than cutting leeks that many people worry about and despise
in the embryonic stage of blockchain development, various enterprises and companies are flocking to the market for fear of falling behind others. This is the case with the market. The early opportunities are not seized, and the last share is just a drop in the bucket for the former.
10. Most business development needs to establish a certain trust foundation, especially in the cross agent scenario. Blockchain can provide very effective help for application scenarios with difficult trust establishment and high trust maintenance cost.
