Do you still remember Satoshi Nakamoto's classic quote 'I want people to see me, but they don't know who I am'? This may be the coolest sentence in the cryptocurrency industry, perfectly interpreting the core spirit of Web3 ——Freedom without permission. In the barbaric era of blockchain, anonymity is our superpower, and everyone is equal before code, whether you are a Wall Street elite or a basement code farmer. But times have changed, my friends. From No Need for License to Accurate Portrait: The Evolutionary Theory of the Coin Circle No need for permission is never meant to make people do shameful things, but for fairness. But the problem now is, how to distinguish between true builders and pure speculators when everyone can participate 'without permission'? How to make the value truly flow to those who deserve it? Simply put, in the encrypted world, the perception of user attributes determines the fairness and efficiency of economic distribution. There are countless projects on the market that identify users. Biometric identification? High cost and significant privacy risks. On chain activity analysis? Witch attacks teach you how to be a person in minutes. Social verification? The brushes have already played this set to pieces. At this point, @ TREX_chain proposed a rather interesting solution: the 5D T-REX Persona system ——A multidimensional user profiling engine that integrates Web2 and Web3. The core logic of T-REX is quite simple and crude: since the problem with Web3 is that it cannot accurately match users and opportunities, then first make the user profile detailed enough, and then use AI to do intelligent matching. It attempts to comprehensively depict user profiles from five dimensions: on chain behavior, social relationships, skill authentication, reputation tags, etc. The project has just been launched and is currently in the early bird stage.

What you should do is to bind all high-quality attributes to the main account, so that the weight is the highest and the airdrop is the most. From the perspective of grooming, T-REX is indeed worth paying attention to. The financing scale of $17 million, endorsement from top institutions, and relatively early participation timing are all factors that airdrop hunters like. More importantly, the design of the Persona system provides early users with a clear path of participation and value accumulation, which is much more transparent than projects that can only "interact and brush volume".
