1. blockchain technology belongs to the software development instry. If the technology is in place, it's certainly not difficult. Otherwise, if you don't know anything about it, it's extremely difficult. You can measure your own level and outsource if you can't
2. Private key~
3. The analysis of Chongqing jinwowo network is as follows:
each node on the blockchain can verify the integrity and authenticity of the account book to ensure that all transaction information is not tampered with, true and effective
every node on the blockchain keeps copies of all transaction information. When the number of data and participants on the blockchain is very large, the cost of modifying information will be very high. At least 51% of the
computing power of the whole network is needed to modify information, and the modification cost may far exceed the expected revenue
when the information of some nodes is maliciously tampered with, other nodes on the blockchain will find the information that has not formed a "consensus" in a short time and maintain and update it.
4. 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
5. Some, such as Tencent security led the blockchain, based on the cryptographic algorithm that can resist the attack of quantum computing environment, created the overall strong security blockchain solution of trusted data.
6. Before we mentioned the decentralized application platform, we always thought of foreign blockchain solutions. But when we talk about this topic today, we think more of our domestic laikelib. Shanghai Heshu software's laikelib blockchain technology infrastructure is a decentralized blockchain application development platform, which aims to help developers quickly create decentralized applications. Laikelib is easy to use, flexible, convenient and safe. In terms of mode, it is similar to Ethereum and belongs to the underlying technical architecture service of blockchain, but the implementation mechanism is slightly different, which can be found on the official website of Heshu blockchain technology.
7. It must be Tencent's security leading blockchain, which is really a good platform. At present, it has been implemented in many scenarios, such as social welfare, government data sharing and exchange, electronic access certificate, supply chain traceability, etc.
8. At present, many friends are in asproex (Apollo). The management of their family is composed of blockchain elites, bank executives and blockchain technology teams. They have rich experience in the blockchain instry and can learn more about it.
