Ethereum

Consensus Mechanisms: Blockchain relies on consensus mechanisms, such as Proof of Work (PoW) or Proof of Stake (PoS), to validate transactions and maintain the integrity of the ledger.

Innovation and Adaptability: Consensus mechanisms are continually evolving, with new approaches being developed to address the limitations of existing methods. Innovations like sharding, hybrid consensus models, and layer-2 solutions aim to improve the efficiency, security, and scalability of blockchain networks.
