Buy LayerZero (ZRO)

Maximum stock 1 billion tokens. Circulating are 115,000,000 tokens, so there is certainly room for dilution by additional tokens.

After the airdrop, receivers immediately started selling LayerZero, causing the LayerZero price to plummet. But the cryptocurrency managed to recover that quickly.

As you can see, it is called V2. Version 1 is no longer actively maintained. Upgrading to V2 is optional.

LayerZero is a messaging protocol, not a blockchain. By using smart contracts on each chain, LayerZero allows different blockchains to communicate fluidly with each other.

LayerZero is an immutable, censorship-resistant and permissive smart contract protocol that allows anyone on a blockchain to send, verify and execute messages (targeted data) on a supported target network.

Before LayerZero hit the market, dApps had to use bridges to send something to another blockchain.

Immutable contracts

LayerZero solves this by creating immutable contracts on a blockchain, which they call the LayerZero Endpoint contract. This type of contract is used in both an Omnichain Application (OApp) and an Omnichain Fungible Token (OFT) Standard.

The OApp Standard gives developers a generic message passing interface to send and receive data between smart contracts on different blockchains. Any form of smart contract can do this, as in a DAO, DeFi or other types.

Modular safety

Applications can have cross-chain messages verified by decentralized verifier networks (DVN). This allows each app to arrange its own security through an OApp Security Stack, eliminating each app's reliance on centrally arranged authentication.

Permissionless execution

Once a message has been verified by a DVN, it can be executed. This can be done automatically by a configured Executor Of an app.

Anyone can develop and run such an Executor themselves. Even if an Executor disappears, messages can still be executed permissibly.

Until now, blockchains worked in isolation. With LayerZero, it's possible to have an interaction with one blockchain (e.g., Ethereum) that automatically triggers a response on another blockchain (e.g., Binance Smart Chain), without a central authority relaying that trigger.

This is at the heart of LayerZero's omnichain messaging, which reshapes the way blockchains communicate with each other.

Smart contracts

These track the state of affairs on a blockchain by keeping track of who has what through the digital ledger. This ledger is the heart of any smart contract.

LayerZero allows your on-chain application to use a particular or any blockchain as a ledger.

Omnichain contract standards

Because each blockchain is simply a digital ledger and there are no rules for what smart contracts should do on such a ledger, developers can create all sorts of omnichain standards that spell out how contracts on different blockchains can work together.

The two standards offered by LayerZero are the OApp and the OFT standard.

To send a cross-chain message, a user must write a transaction on both the source and target blockchains.

A successfully deployed OApp communicates with the LayerZero Endpoint contract to seamlessly send messages via this protocol from the source to the target chain, allowing developers to focus on the implementation and features of the app they are creating without having to write features at the protocol level.

The Endpoint contract uses an on-chain message library configured by the owner of an OApp to use it to determine how to create a message packet. This packet is then sent to the target blockchain as an event, which contains the address, instructions on how to handle a message and the message itself.

Next is the turn of the Security Stack, which monitors security and after confirmation by an Executor, the message will be executed.

For firm security, protocol updates are optional, only OApp owners can change the security configuration, and all core contracts of the protocol immutable, so an upgrade of a smart contracts does not introduce vulnerabilities.

Cross chain networks have hardly any connectivity and often inconsistent communication interfaces. LayerZero aims to solve this by providing a uniform and densely connected mesh (mesh) network to all supported blockchains.

An Omnichain Mesh Network refers to a taut web, where each chain can communicate directly with every other chain by using a predictable and stable interface, so that data and value transfer across different blockchains is fluid. Security is never lost sight of in this process.

Omnichain features

• Universal Network Semantics. Uniform standard to send packets over chains without censorship.

• Modular security model. DVNs verify messages that can be configured. Developers can choose which security and cost-effective models best suit their application. Configurable block confirmations secure an OApp against block reorganizations on the target blockchain. LayerZero Endpoint provides fundamental security against known dangers on a blockchain, such as replay attacks or unauthorized code changes.

• Pathway security. Each path on the Omnichain can configure its own security to best suit its connection.

• Chain Agnostic Applications. OApps use universal semantics, so they work fluidly between different blockchains.

LayerZero provides template contracts that act as a blueprint for the foundation of your app. The OApp gives developers a generic message passing interface to send data and digital assets between contracts on different blockchains.

Whether you want to get started with DeFi or install a DAO, these contract standards make it very easy.

It also allows you to easily send an Omnichain Fungible Token (OFT) across different blockchains.

By using a default OApp Configuration, you can quickly develop your app, without complex setups or configuration afterwards. This is somewhat similar to the ERC-20 technique.

LayerZero Endpoint is an immutable smart contract that implements a standardized interface for OApps, allowing you to manage security configurations and send and receive uninterrupted messages.

Sending Endpoint shows an interface for an OApp contract, which can be used to send messages. The OApp Config created by the app owner enforces the unique message configuration. A library of possible messages controls how a packet is created and sent.

Receiving Endpoint lets DVNs within the Security Stack listen for packets and verify them in the message library selected by the OApp. If the packets pass the security check they are sent to Endpoint and the message is executed for the receiving application.

A message library is compiled by an OApp owner. This is an immutable authentication library that their application uses. The protocol enforces the unique OApp contract configuration before messages can be sent and received.

Message library enforces which Security Stack and Executors the Endpoint works with.

Message Library ensures on the target chain that the Security Stack that configured this OApp has authenticated the packet first, before it goes to the Endpoint.

The message packet standardizes the format and size of messages sent between different blockchains. This packet structure is compatible with blockchains that use different output environments, such as EVM and non-EVM.

The packet structure contains a number of fields to ensure cross-chain security. The nonce (randomly generated unique number from cryptography) prevents replay attacks and censorship. The global unique identifier (guid) is used to track the message cross chain and along different systems. The misdirection of messages is prevented by identifiers for source and target.

This makes messages traceable and ensures the integrity of messages.

Each OApp can configure a Security Stack consisting of a number of mandatory and optional Decentralized Verifier Networks (DVNs) to check message integrity. This can be used to create an optional threshold for final verification of a message nonce.

Each DVN checks that messages are correct with their own verification scheme, before verifying it in the target chain's message library. If everything is correct, the nonce is sent to the target Endpoint messaging channel for output by an Executor.

With a DVN adapter, you can also integrate the security of third-party networks into the OApp Security Stack, such as bridges and middle chains.

A developer can configure the Security Stack to fit the necessary security and efficiency of the app.

Examples of a DVN are: Layerzero Labs (default), Google Cloud, Polyhedra zkLightClient, Nethermind, Horizen Labs, et cetera.

Executors ensure the seamless output of messages on the target blockchain by following instructions set up by the app owner regarding the automatic transfer of omnichain messages to the target chain.

After the Security Stack verifies the message payload, the Executor goes to work delivering the message.

When tracking cross chain messages, a transaction must be confirmed on both the source and target chain.

The Executor is able to pay gas fees on several blockchains, making it unnecessary for other participants to have tokens from all those blockchains.

Benefits of Executors:

• Automatic output on the target chain.

• Gas management. All gas fees can be paid in the source-chain's gas tokens, eliminating gas problems.

• Adjustable gas settings. Message options allow developers to decide how much gas they want to pay for different omnichain messages.

Developers can configure their own Executor. They can use a custom and existing Executor, they can build one themselves, and they can even work without an Executor and leave it to the user.
