LayerZero

LayerZero is a cross-chain interoperability platform that enables developers to create that work seamlessly across multiple through a straightforward and uncomplicated interface. LayerZero was founded by , , and in 2021 and is headquartered in Vancouver, British Columbia, Canada. [1][2][3]

Overview

LayerZero is a messaging protocol, not a . It facilitates seamless interaction between using on each chain, Decentralized Verifier Networks (DVNs), and Executors. Implemented on January 29th, 2024, LayerZero V2 separates message verification and execution, giving developers more control over security and execution. It also offers enhanced message throughput, programmability, and other contract-specific improvements, making it a more flexible and efficient messaging protocol. [16]

The update includes Decentralized Verification Networks (DVNs), which replace the V1 Oracle and allow any entity capable of verifying cross-chain data packets to join LayerZero, promoting decentralization. Adapters for and CCIP DVNs are available on and will be on at launch, with additional adapters planned for 2024 to support various native bridges, third-party bridges, middle chains, , and other verification methods, preventing vendor lock-in. The X of Y of N Verification feature provides a modular approach, enabling applications to customize their security by choosing a combination of DVNs, thus optimizing costs and security levels based on specific needs. [16]

Permissionless Execution introduces Executors, a new role that handles execution on the destination chain separately from verification, simplifying payments and offering customizable settings. Each application must configure a Security Stack comprising DVNs, Executors, chain confirmations, MessageLibraries, and chain pathways, granting full control over security settings. Increased throughput is achieved by offering lazy or strict nonce enforcement options, allowing developers to choose between in-order or out-of-order transaction execution, thereby aligning LayerZero’s throughput with the destination chain’s while maintaining censorship resistance. [16]

Enhanced programmability is facilitated by improved protocol contract interfaces, path-specific libraries, new design patterns, and horizontal composability, fostering flexibility and uninterrupted cross-chain transactions. Unified semantics ensure that applications function uniformly across all blockchains with LayerZero endpoints, including non- chains. Finally, the V2 launch supports forward and backward compatibility, aiding teams building on V1. [16]

Ultra-Light Node

Ultra Light Node (ULN) is a novel cross-chain bridging and messaging approach. ULN combines the security of on-chain light with the cost-effectiveness of middle chains. On-chain light receive and validate every block header for each pairwise chain on the opposing chain, making it the most secure way to transmit messages between chains, but it comes with a high cost. Middle chains, on the other hand, are less secure but more cost-effective. [5]

ULN solves this dilemma by performing the same validation as an on-chain light , but instead of keeping all block headers sequentially, block headers are streamed on demand by decentralized . This eliminates the need for a to store every block header, reducing the storage and computational overhead and making it a more cost-effective solution. The oracles are incentivized to provide accurate and reliable block headers, ensuring the security of the messages transmitted between chains. [5]

Infrastructure of LayerZero

Omnichain Mesh Network

LayerZero addresses the limitations of existing cross-chain networks, which often suffer from sparse connectivity and inconsistent communication interfaces, by providing a uniform and densely connected mesh network across all supported blockchains. An Omnichain Mesh Network allows any chain to communicate with any other chain directly using a predictable and stable interface, facilitating seamless data and value transfer across . The LayerZero protocol maintains consistent security and reliability across all connections, despite varying security semantics and design logic among individual . [21]

The network ensures uniform standards for packet delivery, reliable data transfer without censorship, and packets are delivered exactly once to their intended destinations. LayerZero's modular security model offers configurable and non-configurable security guarantees, allowing developers to choose the security and cost-efficiency models that best fit their applications. Decentralized Verifier Networks (DVNs) verify messages and can be configured by applications, while configurable block confirmations protect against block reorganizations on the source chain. Core security features, such as protection against censorship, replay attacks, and unauthorized code changes, are built into the network's immutable interfaces. [21]

The network recognizes that each pathway might require a different security configuration. Pathways, defined by source , source application, destination , and destination application, can be individually configured to tailor security and cost to the specific needs of each connection. This chain-agnostic approach enables developers to create Omnichain Applications (OApps) that operate seamlessly across . [21]

Endpoints

The LayerZero Endpoint is an immutable providing a standardized interface for Omnichain Applications (OApps) to manage security configurations and send and receive messages seamlessly. A LayerZero Endpoint is divided into four modules: Communicator, , Network, and Libraries. The Communicator, , and Network modules make up the core functionality of the endpoint, while new chains are added as additional Libraries. This design allows for easy support of new chains without modifying the core modules. [3][4]

Utility

LayerZero is a infrastructure that provides a range of utilities to developers and users. Its key features include a cross-chain , multi-chain yield aggregator, and multi-chain lending. These utilities allow for seamless transfer of native assets across different chains, access to high-yield opportunities, and cost-efficient lending options. [4]

Cross-Chain Decentralized Exchange

LayerZero facilitates a cross-chain that operates solely with native assets. Unlike traditional designs that use wrapped tokens or go through intermediary sidechains, LayerZero enables with on both chains, allowing users to deposit their native assets on one chain and withdraw native assets from another. With LayerZero's messaging capabilities, direct bridges, , and other pricing models can be implemented. [4]

Multi-Chain Yield Aggregator

When using LayerZero for cross-chain transactions, a multi-chain yield aggregator could tap into the high-yield opportunities across multiple ecosystems, maximizing access to high-yield opportunities and allowing users to take advantage of market inefficiencies. This would be an improvement over single-chain yield aggregators that restrict their access to yield opportunities outside of their current ecosystem and instead would provide more yield opportunities to choose from. [4]

Multi-Chain Lending

Multi-chain lending on LayerZero allows users to take advantage of opportunities on different chains while consolidating their assets on their preferred chain. Through a lending protocol, users can lend their assets on their preferred chain and borrow the desired asset directly on another chain, eliminating the need for costly intermediary steps like bridge and swap fees. [4]

LayerZero Airdrop

On June 14, 2024, the LayerZero team introduced the 'LayerZero Foundation' and also, , the CEO of LayerZero Labs, released his calculations on the ZRO token in a tweet on X; [17]

Ok let's talk some numbers.
23.8% of the supply is going directly to the community and builders. This does not include foundation, growth, etc. Directly to community. 8.5% of this is being distributed day 1 (5% core, 3% RFP, 0.5% community pool) The majority of the remainder will be given over the next 36 months with additional retroactive distribution every 12 months, along with some forward looking RFPs for builders.... - he tweeted on June 14, 2024 [18]

Per the tweet, ZRO has a supply of 1 billion, of which 23.8% is reserved for allocation to community and builders. 23.8% excludes foundation, growth, and other heads. 8.5% of the tokens allocated to the community and builders will be distributed on the first day of the ; the rest will be allocated within three years. The project plans an additional allocation every 12 months, and some forward-looking Request for Proposals (RFPs) will be provided for builders in the ecosystem. [19]

LayerZero Labs also mentioned June 20 as the date for the token while asking users to determine their eligibility status via the official website. [20]
