The blockchain was born from Nakamoto's bitcoin. The essence of the blockchain is a distributed database built on the principle of cryptography. It is also a trusted and sharable public account, which will be published in accordance with strict rules and openness The agreement to amend, everyone can check it, but no single user can tamper with.
Its core features:
1.Go to the center
The use of distributed accounting and storage, there is no centralized management agencies, the system nodes to jointly maintain the data blocks, all nodes have the same rights and obligations
2.Openness
Blockchain data for everyone to open, in addition to trading parties to the private information is encrypted, the entire system is highly transparent
- Information can not be tampered with
Once validated and added to the blockchain, the information is stored forever, and unless more than 51% of the nodes in the system are under control, modifications to the database on a single node are not valid.
Blockchain is mainly to solve the trust and security issues of the transaction. The various digital currencies that have emerged since 2009 are bitcoin, litecoin, dogecoin, OKcoinetc, all based on the public blockchain. In addition to the application of currency, but also in other areas: smart contracts, securities trading, e-commerce, Internet of things, file storage, authentication, etc.
Gong Xin Bao: Blockchain technology to build a point-to-point decentralized data trading platform to solve data trading problems. Simply put, the public letter Po docking data buyers and sellers, when the buyer needs data, the public letter through the blockchain technology broadcast to the entire network, and data sources by querying their own offline database, if there is relevant data, the data buyers and sellers through the implementation of smart contracts Data transactions, data through point-to-point communication, if not no follow-up operation.
Starlight cloud, through distributed cloud storage and distributed cloud computing, will be applied to the smart city services and the Internet of Things scenarios, including merchant distributed cloud storage, distributed hotel, shared teaching, games, smart living, home and smart Delivery and other links, Starlight cloud in these scenarios, to provide users with the data storage, calculation, acquisition, analysis, processing and other functions.
The above example projects are all applications of blockchain beyond digital currency, perhaps adding more blockchain projects.
