This article will explain in detail the example analysis of the new blockchain database in SunlightDB 2017. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

What is a blockchain? Since last year, the concept of blockchain has been popular, especially in some developed countries. Blockchain has also been given the name of subversion, which has the potential to sweep the world. Blockchain will be the first to hit the financial sector, which in turn will affect the wider economy.

The prediction is based on several core characteristics of the block chain: decentralization, distributed ledger, point-to-point transmission, untamperable and so on. Because the birth of blockchain is magical, and its development has attracted attention with the rise of bitcoin around the world, many people will confuse the relationship between blockchain and bitcoin. Blockchain is actually the underlying supporting technology of Bitcoin, and from a certain point of view, Bitcoin can be seen as the first practical application of blockchain generated at the same time.

Blockchain is essentially a decentralized distributed ledger database. The blockchain itself is actually a string of data blocks generated by using cryptography, each of which contains multiple valid confirmations of bitcoin online transactions. Whenever encrypted transactions occur, miners with powerful computing power in the network begin to use algorithms to decrypt and verify transactions and create new blocks to record the latest transactions. The new block is added linearly to the end of the original block chain in chronological order, and the account book will continue to grow and extend.

Through complex public and private keys, the blockchain network broadcasts the books of all transactions of the entire financial network in real time, distributes the transaction records to each client in real time, and ensures that everyone can only modify their own property. Of course, there are other people's trading records in the ledger, although you can see the value and the corresponding trading address (made up of a long period of disordered letters and numbers). But you can't know the true identity of the trader without borrowing other techniques.

As a specific distributed data access technology, block chain technology participates in the calculation and recording of data through multiple computing nodes in the network, and verifies the validity of its information. From this point, blockchain technology is also a specific database technology. This kind of database can obtain data credibility based on network-wide consensus.

The Internet has entered the era of big data, but at present, our big data is still in a very basic stage. But when entering the blockchain database stage, it will enter the big data era of real strong trust endorsement. All the data in it is of indestructible quality, and no one has the ability or need to question it. From the previous development, we can notice that the development of data is somewhat close to Maslow's hierarchy of needs theory. After realizing the needs of survival and use, it will naturally develop towards higher requirements. Of course, security is only a stage in the development of data, and it will eventually develop towards artificial intelligence, which is the requirement of data self-realization.

SunlightDB 2017 is a decentralized database. Developed in C language, it has the performance of millions of writes per second, PB-level data storage and subsecond response time. SunlightDB was designed from a distributed database, adding many blockchain features through innovation, such as decentralized control, creation and movement of digital assets. SunlightDB inherits the characteristics of modern distributed database: throughput and capacity are linearly related to the number of nodes, fully support SQL query language, efficient query and rights management. Because it is built on existing distributed databases, it also inherits enterprise-level robustness at the code level.

SunlightDB 2017's new blockchain database complements decentralized processing platforms such as Ethernet Fong and decentralized file systems like Inter Planetary File System (IPFS).

As Melanie Swan puts it in her book blockchain: a Blueprint and Guide to the New economy: blockchain is like running a new application layer over existing Internet basic protocols. It enables the Internet to make such as real-time payments or execute more complex forward financial contracts. Any currency, financial contract, digital or physical asset can be exchanged for value through a similar "blockchain system".

And SunlightDB is such a blockchain system.

"do you know what the TCP/IP agreement is?

Actually, you don't need to know.

All you have to do is connect a network cable

You can intervene in the Internet.

It's fine if you can use it.

The same is true of the blockchain. "
