What are the good blockchains

1. The market is roughly divided into
1. The underlying chain platform providers, such as ant / network, usually only provide chain and development tools, but the specific instry / scenario solutions and development delivery capabilities are limited, which is not their focus. They want to use blockchain packaging to sell more cloud services
2. Blockchain solution companies usually provide blockchain solutions in their own familiar fields, but most of them are small and medium-sized teams or start-up teams. Most of them have little difference in blockchain technology capabilities and have a deep understanding of their respective fields
however, the biggest problem for such companies is that because the blockchain instry is still in its early stage and there is no mature business model or profit model, most of them need external investment to continue their life, which leads to the difficulty in guaranteeing their service ability or continuous performance ability, and frankly speaking, their business is unstable
on the other hand, because it is not a professional end-to-end delivery or professional outsourcing, it has no mature methods, team and project management to ensure the efficient and complete delivery of a blockchain solution. So for buyers, it is easy to get out of control in the process of project development, or it is difficult to get satisfactory delivery results in the end.

2. Now the blockchain is in a big fire. Many blockchain companies at home and abroad are developing very well. As I know, we have cooperated with many large enterprises and government departments to solve many problems with blockchain technology. If you don't understand, please feel free to ask questions
3. The development of this instry in the market is particularly good. Now all instries pay more attention to this aspect. First of all, we should choose according to the demand, and also pay attention to the strength and effect of the team. We know that Baker chain blockchain has a good evaluation in the instry, good reputation and good performance in all aspects. You can consult first
4. I feel better
5. There are a lot of blockchains in China, although compared with the number of enterprises in other instries, they are very few. For example, Yingtang Zhongchuang has a good reputation at present, mainly for the underlying technical services and instry solutions of blockchain. That is to say, an underlying blockchain is built, and an adaptation layer is built on it, so that enterprises can quickly establish commercial applications.
6. Blockchain is a key project in the 13th five year plan for national informatization. It is parallel with artificial intelligence, big data, driverless and other projects. With the support of the government, blockchain technology has developed rapidly, and China's blockchain instry is expected to take the lead in the world
at present, the number of domestic blockchain related companies is increasing, among which fast online has always been in the leading position
up to now, we have independently developed 100 + Internet financial procts and provided innovative suggestions and solutions based on our years of instry experience and advantages
as the development platform of blockchain, she only focuses on the innovation of blockchain technology and proct development. There is an overall personalized solution from research and consultation, project start-up to the final system launch and later maintenance upgrade.

7. Blockchain mainly solves the trust and security problems of transactions, so it proposes four technological innovations to solve this problem:
(1) distributed ledger, that is, transaction bookkeeping is completed by multiple nodes distributed in different places, and each node records complete accounts, so they can participate in monitoring the legitimacy of transactions, At the same time, they can testify together
different from traditional distributed storage, the uniqueness of distributed storage of blockchain is mainly reflected in two aspects: one is that each node of blockchain stores complete data according to block chain structure, while traditional distributed storage generally stores data in multiple copies according to certain rules. Second, the storage of each node in the blockchain is independent and has the same status, which relies on the consensus mechanism to ensure the consistency of storage, while the traditional distributed storage generally synchronizes data from the central node to other backup nodes[ 8]
no single node can record the account data separately, so as to avoid the possibility that a single bookkeeper is controlled or bribed to record false accounts. In theory, unless all the nodes are destroyed, the accounts will not be lost, so as to ensure the security of the account data
(2) asymmetric encryption and authorization technology, the transaction information stored on the blockchain is public, but the account identity information is highly encrypted, which can only be accessed under the authorization of the data owner, thus ensuring the data security and personal privacy
(3) consensus mechanism is how to reach a consensus among all accounting nodes to determine the validity of a record, which is not only a means of identification, but also a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and achieve a balance between efficiency and security
the consensus mechanism of blockchain has the characteristics of "the minority is subordinate to the majority" and "everyone is equal", in which "the minority is subordinate to the majority" does not completely refer to the number of nodes, but also can be the computing power, the number of shares or other characteristics that can be compared by computers“ "Everyone is equal" means that when the nodes meet the conditions, all nodes have the right to put forward the consensus results first, and then directly recognized by other nodes, and finally may become the final consensus results. Taking bitcoin as an example, the workload proof is adopted. Only when more than 51% of the accounting nodes in the whole network are controlled can a nonexistent record be forged. When there are enough nodes in the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
(4) smart contract, which is based on these trusted and tamperable data, can automatically execute some pre-defined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and reliable, it is easy to carry out automatic claim settlement in some standardized insurance procts

8. Bochat is good. You can chat and trade
9. 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.
10. Coin security is the No.1 exchange in cryptocurrency, which means that coin security has a more complete ecology than Ethereum. In the future, the public chain can feed back the business of coin security master station, so from the perspective of ecology, coin security has a larger pattern.
