2.
A vigorous "blockchain movement" is sweeping like a wave, threatening everyone around. From last year to this year, the debate over blockchain has never stopped. Is blockchain, as its advocate Chen Weixing said, the "spring of mankind", the "antidote to the global economic collapse", or as his doubter Zhu Xiaohu said, "blockchain is a fake outlet, and there is nothing left except currency speculation"
we think that this instry needs standards, otherwise we will talk about blockchain for a long time, and the concept of talking is not the same, and even some enterprises claim to make their own blockchain, and they just change the database. With the authoritative standard of trusted blockchain, we can screen out the enterprises that obviously sell dog meat, and let the enterprises that really do blockchain technology get endorsement
Ce: how does Tencent solve the problem of talent scarcity in the blockchain field
CAI Yige: our technical talents are basically transformed from Tencent. The blockchain instry is very new, and few people have done blockchain. Just like the arrival of mobile network in those years, it's very difficult for you to recruit Android and IOS developers. We all cultivate ourselves
3. Generally speaking, blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer
among them, the data layer encapsulates the underlying data block and related data encryption and timestamp technologies; The network layer includes distributed networking mechanism, data transmission mechanism and data verification mechanism; The consensus layer mainly encapsulates all kinds of consensus algorithms of network nodes; The incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; The contract layer mainly encapsulates all kinds of scripts, algorithms and smart contracts, which is the basis of the programmable characteristics of blockchain; The application layer encapsulates various application scenarios and cases of blockchain. In this model, chain block structure based on timestamp, consensus mechanism of distributed nodes, economic incentive based on consensus computing power and flexible and programmable smart contract are the most representative innovations of blockchain technology.

4. 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

6. The only criterion for investing in a project is whether the project can make money for itself
blockchain projects are also projects. If you want to add value to your investment, you need to have the following aspects:
1, self-development ability, complete business system and investment guarantee mechanism. This is very important. Many projects do not mention the investment guarantee mechanism, which is to leave a way out for the future
PS: it's said that the project of global integral treasure is quite good. You can pay attention to it.
