1. Decentralization
Traditional currencies are usually issued and managed by central banks, while many cryptocurrencies run on blockchain networks and are jointly maintained by global nodes.
2. Blockchain technology
Blockchain is an open and transparent distributed ledger. All transaction records are encrypted and permanently saved, making them difficult to tamper with.
3. Global circulation
As long as there is Internet, users can transfer and trade money globally.
4. Anonymity and publicity coexist
The account address usually does not directly reveal the real identity, but the transaction records are publicly recorded in the blockchain.

Cryptocurrency assets are stored in the wallet
The transaction is verified through the blockchain network when transferring
After verification is completed, it is recorded in the blockchain
The entire process is ensured by cryptographic algorithms to ensure security.
