2. All Transactions and Interaction Information Experienced by NFTs Will Accumulate on the NFT Itself, Not Lost Due to Transfer

Past
In the past, purchasing NFTs was like buying a blind box. Although you owned the NFT, you knew nothing about its past. You didn't know who created it, its transaction history, whether it had been stolen, and so on. This lack of transparency and traceability made many people concerned about the security of NFTs.
Now
With the ERC6551 protocol, the transparency and traceability of NFTs have been greatly improved.
Transparency: All information related to NFTs will be publicly available for anyone to view. This means you can easily understand the history and ownership of NFTs, making wiser purchasing decisions.
Traceability: You can query all on-chain data associated with the TBA account address corresponding to the NFT, including transaction records, interaction records, and attribute information. This allows you to understand the usage and value of NFTs, ensuring their authenticity and security.
Examples
Game Character NFTs: You can query the on-chain data of an NFT to understand how many battles it has participated in, what rewards it has received, and which players it has interacted with. This information can help you evaluate the value and rarity of game character NFTs.
Collectible NFTs: You can query the on-chain data of an NFT to understand its origin, creation process, and transaction records. This information can help you verify the authenticity and value of collectible NFTs.
As NFT technology continues to develop, the transparency and traceability of NFTs will further improve. This will make NFTs more secure, reliable, and open up new possibilities for their application.
Summary
Past: NFTs lacked transparency and traceability, making purchasing NFTs akin to buying a blind box.
Now: With the ERC6551 protocol, the transparency and traceability of NFTs have been greatly improved.
Future: The transparency and traceability of NFTs will further improve, making NFTs more secure and reliable.
3. Receive Airdrops Without Snapshot, Directly to Each NFT's Corresponding TBA Account Address

Past
In the past, NFT airdrops usually required a snapshot. The official announcement would specify the snapshot time and record all addresses holding NFTs at that time. Then, airdrop rewards would be distributed to these addresses.
This method had the following issues:
High Workload: Officials needed to manually take snapshots and verify the validity of all addresses, increasing the workload.
Unfairness: If users who held NFTs before the snapshot time subsequently sold them, the new buyers would not receive airdrop rewards.
Now
With the ERC6551 protocol, NFT airdrops can be easier, more convenient, and safer.
No Snapshot Needed: Officials can directly distribute airdrop rewards to the TBA account address corresponding to each NFT, without the need for a snapshot.
Fairer: All users holding NFTs will receive airdrop rewards, regardless of whether they held the NFTs before or after the snapshot time.
Safer: TBA account addresses are unique and cannot be forged, reducing the risk of fraud.
Examples
A project wants to airdrop tokens to all users holding its NFTs. In the past, the project would need to take a snapshot and verify all addresses. Now, the project can directly distribute tokens to the TBA account address corresponding to each NFT, without the need for a snapshot.
A game wants to airdrop in-game items to all players who participated in game testing. In the past, the game would need to record all addresses of players who participated in game testing. Now, the game can directly distribute game items to the TBA account addresses holding game character NFTs.
Summary
Past: NFT airdrops required snapshots, leading to issues such as high workload, unfairness, and high fraud risk.
Now: With the ERC6551 protocol, NFT airdrops can be easier, more convenient, and safer.
Future: NFT airdrops will become more widespread and open up new possibilities for the application of NFTs.
4. The Combination of NFTs and AI: A Key Innovation in Web3

The combination of NFTs and AI is one of the most important innovations in the Web3 field in recent years. Each NFT can embody an AI Agent, which can carry assets and engage in any interaction, with users only needing to send it intent commands.
Using NFTs to carry AI Agents has several significant advantages compared to authorizing directly through wallets:
1. Advantages of NFT's Uniqueness and Non-Fungibility for Agents:
Scarcity: Each NFT is unique, meaning each Agent is also unique. This scarcity increases its value.
Ownership Protection: The non-fungibility of NFTs ensures the ownership of Agents is clear and tamper-proof, protecting the rights of Agent developers and preventing theft or misuse.
2. Programmability and Scalability:
TBA accounts of NFTs can contain rich metadata, including descriptions, attributes, and skills of Agents. This allows the creators to give Agents more functions and characteristics, providing a richer and more personalized interaction experience.
3. Transparency and Verifiability:
NFTs are stored on the blockchain, and their transaction history and ownership changes are public, transparent, and verifiable. This closely binds the interaction data and revenue records of Agents to themselves, enhancing trust and traceability.
4. Establishing a Trading Market:
Through NFTs, it is convenient to establish a trading market for AI Agents. Buyers and sellers can freely trade Agents on the market, and the scarcity and uniqueness of NFTs provide value support for the market. Additionally, leasing and lending markets based on NFTs can achieve more flexible pricing mechanisms and broader participant groups.
5. Serving as a Data Access Layer (DA Layer):
The rich database carried by independent Agents can become a key component of the data access layer (DA Layer) of the Web3 network. This design enables Agents to seamlessly interact with other Web3 applications and services, facilitating smooth data sharing and efficient exchange. This interoperability not only strengthens the connection between various components in the Web3 ecosystem but also helps build a more open, collaborative, and intelligent overall environment.
