ChainIDE#33 What does the era of Full-chain NFT mean?

[子小艺]

Much of the buzz around Omnichain stems from the rise of LayerZero Labs, a Canadian-based team that created the interoperability protocol LayerZero.
Simply put, LayerZero is a messaging layer designed to make it easy for smart contracts to communicate between many blockchains, or indeed any blockchain.
The protocol was initially launched to support EVM compliant projects, namely Ethereum, Arbitrum, Avalanche, BSC, Fantom, Optimism, and Polygon. The LayerZero team also plans to add support for non-EVM chains such as Cosmos Hub and Terra in the future.
LayerZero stands out for its use of ultralight nodes (ULNs), which provide a new model for securely transferring messages between chains in an economical and efficient way.
Therefore, LayerZero's omnichain messaging model differs from the cross-chain model, which requires the use of bridge protocols to migrate or encapsulate assets directly to other chains. For example, if I bridge ETH to Ronin bridge to use Katana decentralized exchange (cross-chain application), my ETH will be transferred directly from Ethereum to Ronin.
The omnichain model also contrasts with the multi-chain model, in which independent communities with different values pursue their own technology stack.
Gh0sts, the first NFT project based on the cross-chain interoperability protocol LayerZero, is the first all-chain (Omnichain)NFT series, with a total of 7,710 NFT being cast for free on 7 supported blockchains. These include Ethereum, Binance, Avalanche, Polygon, Arbitrum, Fantom and Optimism.

On April 5th, this series successfully topped the trading volume of Opensea for nearly 24 hours. The floor price of Opensea Ethereum once reached 0.88ETH(the actual floor price needs to integrate the market data of all 7 chains), but now it has dropped to 0.15ETH, and the total trading volume has exceeded 5,400ETH(nearly 14.5 million US dollars).
After being born on a source chain, a ghostly Gh0sts can contract to move directly between other chains and obtain NFT assets on the target chain that are recognized by the contract. As an example, let's say a user decides to cast his NFT on Avalanche (perhaps to save some Gas). Later he decided to use his Gh0st as his PFP on Twitter (which currently only supports Ethereum mainnet authentication), so he used LayerZero's "traverseChain" feature at Avalanche, with the target chain set to Ethereum. Finally, this NFT can be verified as an ethereum contract asset by the main network in Ethereum.

Discussion:

1. What areas do you think full-chain technology can be extended to in the future and what impact will it have?
2. Do you think full-chain NFT will be the trend of future NFT?
