Day365： Blockchain, Bitcoin Web3， What is their relationship?

1、 Blockchain, the technological cornerstone of Bitcoin

Blockchain is a distributed database technology that ensures the security and immutability of data by dividing it into a series of blocks connected in chronological order. Each block contains a certain number of transaction records and other metadata, as well as the digital fingerprint (hash value) of the previous block, forming an immutable “chain”.

The core characteristics of blockchain:

Decentralization: Blockchain technology does not rely on any centralized institutions or servers, but is jointly maintained through nodes on the network.

Transparency: All transaction records on the blockchain are publicly transparent and accessible to anyone, but the identity of the trader is anonymous.

Non tampering: Once data is written into the blockchain, it cannot be altered or deleted. This feature makes blockchain a reliable way of data storage.

Security: Blockchain uses cryptographic techniques to ensure the security and integrity of data, preventing malicious attacks and data tampering.

Application scenarios of blockchain:

In addition to digital currencies such as Bitcoin, blockchain technology is also widely used in various fields such as smart contracts, supply chain management, the Internet of Things, healthcare, government affairs, justice, energy, and manufacturing. Through…
