What is Blockchain?
In essence, blockchain is a distributed and decentralized network database system. All node maintainers jointly manage, transmit and synchronize data, store data in block and chain structure, and use cryptography to guarantee the security of transmission and access, which can realize a technical system where data is stored consistently and cannot be manipulated or changed.
What is Address?
Calculated by a series of cryptographic algorithms, address is a long string of character codes. Each wallet has a unique address, and once created, all blockchain wallet addresses cannot be changed. The address is like a "bank account" for transferring or receiving money.
