The role of beacon chain: the core engine of Ethereum 2.0

Beacon chain is the core of Ethereum 2.0. Its main function is to manage the PoS consensus mechanism and select and manage validators to participate in block creation and verification, thereby improving efficiency and reducing energy consumption. It is responsible for the staking, activation and exit process of the verifier and coordinates the verifier committee to vote on the block to ensure network security and transactions are carried out in an orderly manner. In addition, the beacon chain is also responsible for the generation of random numbers, the implementation of reward and punishment mechanisms, and cross-shash management, which ultimately ensures the security and stability of the entire Ethereum network.

Beacon chains, as the core engine of Ethereum 2.0, play a multi-faceted and important role, as follows:

1. Consensus mechanism management: Introduce and manage PoS consensus mechanism, select verifiers to create and verify new blocks based on factors such as the number of pledged Ether coins. It is more energy-saving than PoW and reduces hardware dependencies.
2. Verifier Management: Responsible for the pledge, activation, and exit of the verifier. The verifier needs to pledge 32 ETHs, and wait for activation in the queue after pledging, or you can choose to exit.
3. Coordination and Organizational Functions As the coordination center of the entire Ethereum network, the organization validators form a committee to vote on the proposed blocks to ensure that the verification and confirmation of blocks in the network are carried out in an orderly manner.
4. Random number generation: Generate random numbers for the system, used to randomly select verifiers, assign verification tasks, etc., to ensure the fairness and randomness of the network and prevent malicious manipulation.
5. Reward and Punishment Management: Give ether coin rewards to validators who are correctly verified and actively participated, and punish those who are offline or malicious behavior, such as reducing rewards, deducting pledge coins, and maintaining network security and stability.
6. Cross-shash management: manages many shard chains, provides a consensus basis and coordination mechanism for shard chains, promotes cross-shash transactions, records and updates the status of each shard chain, and ensures smooth cross-shash operation.
7. Save network security: Through PoS consensus and verifier management, ensure that only verified legal blocks are added to the chain, prevent malicious attacks and data tampering, and ensure network security and data integrity.
