LayerZero is an omnichain interoperability protocol that enables seamless and secure communication and transactions across multiple blockchain networks. It aims to facilitate cross-chain integration and create a more interconnected blockchain ecosystem by allowing different blockchain networks to communicate effectively.
LayerZero functions using a unique approach where its core components include Ultra Light Nodes (ULNs), allowing transactions to be verified without heavy node requirements. It uses immutable Endpoints deployed on each blockchain to act as entry and exit points for messages. Verification of cross-chain messages does not rely on traditional consensus mechanisms but instead employs a modular security system involving oracles and relayers, ensuring secure verification and execution.
LayerZero can be utilised in various scenarios, including:
LayerZero was founded by Bryan Pellegrino, Ryan Zarick, and Caleb Banister, who were inspired to solve blockchain communication issues. It has gained significant market presence, made notable achievements like processing over 50 million cross-chain messages, and received substantial funding to support its growth. Major developments include its v2 upgrade, which improved security and interoperability across over 40 blockchains, and the planned launch of its native token, ZRO, in 2024.
