As we wrote before, many NFT storage methods are fragile to some extent, and worse, can be destroyed. If the NFT contract points to a centralized server or even IPFS, purchasing the NFT may give you a 404-it is usually only a matter of time.
Arweave solves the problems of NFT storage, metadata permanence and even smart contracts. But until recently, people paid attention to this issue. As we begin to see OpenSea better NFT and other major markets and Arweave integration and the connection Arweave casting NFT technology to other chains, the need for a truly decentralized NFT casting method of the artist, the future looks Very bright, no steep learning curve.
Koii Network, the creator of the new attention economy, has just released a set of atomic NFT standards. This standard and peripheral technologies such as Finnie will enable creators to cast their NFTs at a very low cost and ensure that they will always exist. Let us have a deeper understanding of what an atomic NFT is and how it works.
NFT and atomic NFT
NFTs are traditionally created by writing custom smart contracts and linking the generated tokens to the asset URL. Whether it is a one-time NFT or an algorithm-generated collection, the amount of work to write a smart contract is as much (or more) as it sounds. In addition, URLs linked to NFT assets are full of centralization and reliability issues. NFT OG (team dota) and one of the most valuable CryptoPunks in the world have recently experienced downtime, and 404 processing has been performed on all centralized resources pointed to by punk NFTs.
When larvalabs.com goes down, is my CryptoPunk still valuable or is it also a loss of impermanence?
For a more reliable, cheaper, and less time-consuming method, check out Atomic NFT.
Atomic NFT is a single Arweave transaction, including:
- Asset file
- Metadata file
- Smart contract
This makes all content permanently immutable and permanent, so collectors don’t have to worry about broken NFT links they own within 5 years, and artists don’t have to worry about continuing to pay for their centralized storage solutions.
Examine atomic NFT standards
Koii atomic NFT objects are stored in the state of the SmartWeave contract. Each NFT has an owner, title, artist name, description, and other metadata that enables the surrounding code to perform its function:
Koii provides three SmartWeave contract templates, each of which is designed for different purposes:
- Standard NFT, similar to uploading and deploying content for each new koi.rocks or Finnie Wallet;
- ERC-1155 compatible bridges a contract can be transferred to the NFT Ethernet Square main network;
- Dynamic NFT contracts, used to deploy NFTs that evolve based on specific conditions;
The new document site atomicnft.com shares the txid of each contract for inspection and use.
Koii has prepared a sample function to facilitate the transfer of NFT to the new owner. This makes it possible to develop a market application linked to this function to buy and sell atomic NFTs.
Koii is built on the basis of static NFT and also supports dynamic NFT. The example below is the daffodil NFT, which blooms when it receives attention (to earn KOII).
Since SmartWeave contracts are as programmable as traditional Ethereum smart contracts, art of any complexity can be creative in the process of interacting with art.
Use Koii and Arweave to create atomic NFT
Koii offers several cheap and permanent methods for casting atomic NFTs.
The first method is through koi.rocks , which is a follower leaderboard, you can earn KOII every time you check the NFT.
Another way is to use Finnie Wallet -a Koii browser extension similar to ArConnect or MetaMask. Finnie stores all uploaded content in a gallery and will soon provide the ability to bridge NFT to other chains.
The third method is the most technical but also provides the most control- using Koii’s pre – made SmartWeave contract .
You can find contracts and examples on how to use them on the atomicnft.com documentation site. One of the best things about this method is that the bridging function has been provided; NFTs using Koii ERC-1155 contracts can be found in OpenSea and Rarible, etc. On the popular market.
Transaction Atomic NFT
Except for the NFT minted with Koii’s custom ERC-1155 contract, atomic NFT trading is not yet fully supported-but the features that support it are very close to release.
Finnie is enabled by browser extensions to upload NFT, in order to bridge to Ethernet Square, Polkadot , Tezos, Binance and Avalanche. There is currently a buy button on koi.rocks, which will use Verto’s newly launched NFT market, but the integration has not yet been completed.
Verto has also worked closely with Koii to allow any atomic NFT to be listed, which will provide great possibilities for creators to monetize their work.
There is also a public poll requesting that OpenSea directly support Arweave and Koii NFT on the platform, you can support it here (https://opensea.nolt.io/1499).
