What is the core content of blockchain?

Blockchain is a distributed, immutable ledger technology that records all transaction records and is shared through the entire network. Its core contents include:

1. Distributed ledger:

Blockchain stores transaction records in a distributed ledger scattered on multiple computers (called nodes). This eliminates the risk of a single point of failure because there is no centralized storage point that can be compromised or tampered with.

2. Non-modifiable:

Once a transaction is recorded on the blockchain, it cannot be changed or deleted. This is achieved through cryptographic hash functions and consensus mechanisms that ensure the security and irreversibility of the ledger.

3. Transparency:

All transaction records on the blockchain are visible to everyone on the network. This increases transparency and accountability as everyone can review and verify transactions.

4. Consensus mechanism:

The consensus mechanism is the protocol used by the blockchain network to reach consensus and verify transactions. By using proof-of-work, proof-of-stake, or other consensus algorithms, nodes can agree on the valid state of the blockchain.

5. Smart Contracts:

Blockchain allows the creation and deployment of smart contracts, which are programs that are stored on the blockchain and automatically execute predefined rules. This enables developers to create decentralized applications (dApps) without relying on centralized intermediaries.

6. Decentralization:

The blockchain network does not rely on any single entity. Instead, it is controlled by nodes dispersed across the globe. This eliminates the risk of centralized control and ensures the network is resilient and censorship-resistant.
