Make money in blockchain

Applications, whether websites or apps, have the right to get your clipboard, that is, when you copy a paragraph, they can steal your copied content like a ghost without your knowledge.

Because the interface for obtaining the copy clipboard is a standard general interface, we also enjoy the convenience of this interface in our daily life and work. For example, when I copy my newly published article on the network, it will be automatically recognized immediately. After I click the pop-up window, I can automatically paste the article link in, which is very convenient.

The core problem to be solved by blockchain is how to establish a "trust" ecosystem to meet the occurrence and development of economic activities under the environment of asymmetric and uncertain information. This problem is called "Byzantine general problem", which is a difficult problem in information machine interaction in a distributed system, that is, how to create a consensus basis for secure information interaction without worrying about data tampering when any node in the whole network cannot trust the other party communicating with it. Blockchain uses the algorithm proof mechanism to ensure the security of the whole network. With it, all nodes in the whole system can automatically and safely exchange data in a de trusted environment.

Combined with the definition of blockchain, blockchain will realize four main characteristics: decentralized, trustless, collective maintenance and reliable database. And the other two features will be derived from the four features: open source and anonymity. If a system does not have these characteristics, it cannot be regarded as an application based on blockchain technology.

[definition]

The strict definition of blockchain refers to the distributed database technology that multiple nodes in the peer-to-peer network jointly maintain a continuous growth chain list ledger constructed by time stamps and orderly recording data blocks through the consensus mechanism designed based on cryptography technology. The technical scheme allows any number of nodes in the participating system to calculate and record all the information exchange data in the system for a period of time into a data block through cryptographic algorithm, and generate the fingerprint of the data block for chain and verification. All participating nodes of the system jointly determine whether the record is true.
