① What is blockchain technology.ppt

Explain in layman’s terms: If we assume that the database is a ledger, reading and writing the database can be regarded as a kind of accounting The principle of blockchain technology is to find the fastest and best person who can keep accounts within a period of time, let this person keep accounts, and then send this page of information in the ledger to everyone else in the entire system. This is equivalent to changing all the records in the database and sending them to every other node in the entire network, so blockchain technology is also called a distributed
ledger.
Bitcoin, Litecoin, smart contract platform Ethereum, and distributed content publishing platform DECENT all use blockchain technology.

② What is blockchain ppt

From an academic perspective, blockchain is a new application of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. model. Blockchain is essentially a decentralized database.
For example, if you are a woman, every time your boyfriend says something disgusting to you or promises to buy you something, you immediately record it and send it to all your best friends, classmates, Colleagues, as well as various groups and circles of friends, make it impossible for him to deny it anymore. This is called blockchain.
The core advantage of blockchain technology is decentralization. It can achieve decentralized credit in a distributed system where nodes do not need to trust each other by using data encryption, timestamps, distributed consensus and economic incentives. Point-to-point transactions, coordination and collaboration, thus providing solutions to the problems of high cost, low efficiency and insecure data storage common in centralized institutions.
The application fields of blockchain include digital currency, certificates, finance, anti-counterfeiting and traceability, privacy protection, supply chain, entertainment, etc. With the popularity of blockchain and Bitcoin, many related top domain names have been registered. , which has had a relatively large impact on the domain name industry.
