LayerZero is a full-chain interoperability protocol that allows applications deployed on different chains to communicate with each other without any intermediate chain or consensus mechanism. As an important information transfer foundation, LayerZero opens up a new dimension of cross-chain composition and functionality.

Before LayerZero appeared, the most vocal solutions in the cross-chain market were Cosmos and Polkadot.

Polkadot achieves cross-chain communication through repeaters and parachains, allowing parachains and repeaters to share a security model, but if consensus damage occurs, liquidity on all chains can be stolen immediately, which cannot guarantee all blocks chain security. Cosmos uses IBC, Hub, and Peg Zone to achieve interoperability between chains, and requires Cosmos Hub to decide which Zones can connect to it through governance, and unselected Zones can choose other methods, which provides network Great flexibility. Zone needs to pledge a certain amount of ATOM to connect to Cosmos Hub. The process is relatively simple and fast, and the cost is also low, but this is also considered to be one of the reasons why it is vulnerable to attacks, and it also has security risks.

And LayerZero combines the advantages of the above two solutions, through the "Ultra Light Node" (ultra-light node) to achieve not only connecting every contract on a blockchain chain, but also connecting to any other blockchain for each contract. A security layer is established through the open relayer system and the security properties of established oracles (Chainlink and Band) to achieve the dual purpose of security and cost-effectiveness.

In addition to security, LayerZero also means that users can perform pledge transactions, mint NFT, and play games without knowing the underlying chain that executes the transaction. These only need to be executed with one transaction, and the agreement will The chain with the lower gas fee is automatically selected for execution.

• StargateFinance（https://stargate.finance/）

StargateFinance is a composable Omnichain native asset bridge, allowing users and dApps to transfer native assets across chains while accessing the protocol's unified liquidity pool. About two weeks after its launch, StargateFinance reached a TVL of about US$4 billion, and it was launched on Ethereum, Polgon, Avalanche, BNB Chain, Fantom, Arbitrum, and Optimism. The top three chains with liquidity are Ethereum, BNB, and Avalanche. At present, the TVL of StargateFinance has reached 2.5 billion US dollars.

Full chain NFT

• gh0stlygh0sts（https://linktr.ee/gh0stlygh0sts）

Gh0stly Gh0sts is the first full-chain NFT (omnichain NFT), based on the cross-chain interoperability protocol LayerZero, which can be issued on multiple chains and realize atomic-level cross-chain transfers between multiple chains. Gh0stly Gh0sts A pfp collection of ghost images with a total supply of 7710, also supports mint on seven different blockchains (Ethereum, Polygon, Arbitrum, Optimism, BSC, Avalanche, Fantom). Each NFT will use the background color to represent its birth chain, and the border color to represent the current chain. For example, yellow represents the BNB chain, and a gray border represents Ethereum.

Gh0stly Gh0sts released mint at a free price on April 4th. On April 5th, it once rushed to the top of the OpenSea daily trading list. It broke through 1 ETH for a short time. The current floor price is 0.484 ETH, and the transaction volume is 5.3K ETH.

• tiny dinos（https://linktr.ee/tinydinosnft）

tiny dinos is also a full-chain NFT, containing 10,000 pixel dinosaur pfp, which can be mint free on 7 chains. Two days after mint was released, tiny dinos began to receive a lot of attention, with sales of 2,000ETH within 10 days, making it stand out among many blue-chip projects. At present, the floor price of tiny dinos is 0.227ETH, and the trading volume is 2400ETH. In the past 24 hours, a total of 283 pieces were sold, approximately 64.28 ETH, with a daily sales increase of 0.08%.

working principle:

working principle:

1. Each NFT collection has a source chain;

2. When bridging from its source chain, the NFT is transferred and locked in Parakeet's bridge contract, and a new NFT is minted on the target chain;

3. When transferring on 2 non-source chains, Parakeet uses a burn and mint mechanism where the source NFT is destroyed and a new NFT is minted on the target chain. 4. When transferring from a non-source chain to the source chain, the source NFT is destroyed, while the originally locked NFT on the original chain is unlocked and transferred.

Currently, parakeet.dao is in the testnet stage, now you can visithttps://faucet.paradigm.xyz/Receive test tokens and enter the official website to connect to the Rinkeby test wallet to transfer NFT between different chains.

• Catddle（https://catddle.com/）

Catddle is the first full-chain NFT cat raising game, using the first ERC721-O protocol to develop NFT smart contracts. ERC721-O is an extension of the ERC721 protocol. It adopts a LayerZero-based cross-chain solution. At the same time, it adds a non-blocking extension of NFT cross-chain on the basis of the original ERC721. properties and status.

• Omniverse DAO（https://twitter.com/omniversedao）

Omniverse is an ecosystem of community-driven worlds, games, and dApps, all connected through a seamless interoperable experience.

Omniverse currently has two major products:

Omni Wars It is a full-chain competitive to earn (C2E) strategy game developed by Omniverse DAO. OmniWars can achieve seamless interoperability between chains through the LayerZero protocol to bring a real metaverse experience. The game is expected to be out of beta at the end of the year.

Omni X A set of smart contract implementations and interfaces to support full-chain DAOs, NFT marketplaces, and GameFi projects. Omni X will include full-chain tools such as: gnosis secure multi-signature, game NFT market framework, governance platform, full-chain ERC-20, ERC-721 and ERC-1155 token standards for full-chain companies and communities. It is expected to be released in the third quarter.
