Layer 1 security refers to the protective measures implemented at the base layer of a blockchain network. This foundational layer is responsible for processing transactions and maintaining the integrity of the ledger. Security at this level is critical because it directly affects the network’s reliability and resistance to attacks. Common security mechanisms include consensus algorithms like Proof of Work or Proof of Stake. These algorithms ensure that transactions are validated correctly and that the network remains decentralized.Additionally, Layer 1 security involves safeguarding against various threats, such as double-spending and Sybil attacks. Network participants must validate transactions and reach consensus to prevent malicious activities. Overall, robust Layer 1 security establishes trust among users and supports the long-term viability of the blockchain network. It plays a crucial role in ensuring that all transactions are transparent, traceable, and secure.
