☞ Blockchain technology refers to a way for all people to participate in bookkeeping. There is a database behind all systems, and you can think of the database as a big ledger. Currently, they keep their own accounts.
☞ Since there is no centralized intermediary organization, letting everything run automatically through pre-set procedures can not only greatly reduce costs, but also improve efficiency. And since everyone has the same ledger, it can ensure that the ledger recording process is open and transparent.
☞ Blockchain technology is the underlying technology of Bitcoin. Bitcoin has been running very stably for many years without any centralized organization operation and management, without any problems. So some people noticed its underlying technology, abstracted Bitcoin technology, and called it blockchain technology, or distributed ledger technology.
☞ According to a report released by Spain's largest bank Santander, if blockchain technology is used internally by banks around the world around 2020, approximately US$20 billion in costs can be saved each year. Such data is sufficient to illustrate the huge changes and breakthroughs that "blockchain" has brought to the traditional financial field.
☞ Cloud computing is usually defined as the provision of dynamic, easily expandable and often virtualized resources through the Internet, but it is often a centralized organization that provides the cloud computing platform.
The network composed of the blockchain generally has no specific organization, so the blockchain is closer to the definition of a distributed computing system and belongs to a type of distributed computing.
☞ Q Coin is a centralized electronic currency, including the total amount and the way of issuance is controlled by Tencent.
The total amount of Bitcoin and the issuance method are all pre-set by programs and encryption algorithms and run on multiple nodes around the world. No one or organization can modify it, and it is not controlled by any single person or organization.
Q coins are generally called electronic money, or corporate tokens. We call Bitcoin as digital currency or encrypted digital currency.
As a brand-new rule and transaction method, the core of blockchain is decentralization and weakening of credit, which brings about a highly efficient and secure big data sharing model. As a sunrise industry, blockchain is a future trend, but it is also an investment direction that needs to be treated with caution and fully understood.
