Top Tips for Finding High-Quality but Cheap Blockchain Courses

Blockchain technology has attracted widespread attention in multiple fields in recent years. From developers to business analysts to entrepreneurs, more and more people are aware of the importance of mastering blockchain technology. However, the high cost of learning blockchain technology makes many learners hesitate.

1. What is blockchain?

1. Definition of blockchain

Blockchain is a distributed database that connects information data blocks in chronological order through a "chain structure" and records and verifies them in an encrypted manner.

Block: a storage unit of data, each block contains transaction records, timestamps, hash values of the previous block and other information.

Chain: a chain structure that connects all blocks through encryption algorithms to ensure data continuity and security.

2. Three core features of blockchain

Decentralization: data is not stored in a single server or organization, but distributed on multiple nodes to avoid single point failure.

Immutability: through encryption and consensus mechanisms, any stored data cannot be easily modified or deleted.

Transparency: all participants can view ledger records to increase trust (depending on whether it is a public chain or a private chain).

3. Classification of blockchain

• Public blockchain

Features: completely open, anyone can participate in transactions and verification.

Application: cryptocurrency networks such as Bitcoin and Ethereum.

• Private Blockchain

Features: Only specific organizations or individuals are allowed to access.

Applications: Internal data management and auditing of enterprises.

• Consortium Blockchain

Features: Jointly managed by multiple organizations, participants must obtain authorization.

Applications: Supply chain management, interbank payments.
