Blockchain is a new technology that is gradually emerging with the increasing popularity of digital cryptocurrencies such as Bitcoin.

You can implement your own blockchain with less than 200 lines of Go code! Sounds interesting? What better way to learn than to develop a blockchain of your own? Then let's practice together!

In the case of Bitcoin transactions, blockchain trading is not a transaction in the usual sense of hand-delivering, but a transfer. If each transfer needs to construct a transaction data, it would be awkward.

The scalability of the system is the main reason for promoting the development of NoSQL movement, including distributed system coordination, failover, resource management and many other features. That makes NoSQL sound like a big basket that can be stuffed with anything. Although the NoSQL movement does not bring fundamental technological changes to distributed data processing, it still leads to extensive research and practice on protocols and algorithms. It is through these attempts to gradually summarize some effective database construction methods. In this article, I will focus on the distributed features of the NoSQL database ...

PGP itself is a data security product, what security problems does it have? "No data security system is unbreakable," Philzimmermann, author of PGP, said in the PGP document. "PGP is no exception. We look at its security vulnerabilities in order to let users know what will degrade the security of PGP and how to avoid them. Here are the vulnerabilities: passwords or private key leaks, public key tampering, files that you delete are restored, viruses and Trojan horses, physical security is violated (physical security refers to the security of physical resources such as computers) 、...
