DeFAI seems to be the first hot trend for 2025. DeFAI, merging AI automation with decentralized financial innovation. Let me get this out of the way first, I am no expert on DeFAI just learned about it over the weekend. Nothing here is financial advice or recommending you register DeFAI domain names. Reporting on what I am seeing and providing some research info. If you are well heeled on this topic please leave a comment.
CryptoBriefing.com published an article that delves into the topic.
From the article:
DeFAI, the intersection of artificial intelligence (AI) and decentralized finance (DeFi), is rapidly transforming the crypto industry.
This emerging term, though inclusive of AI agents and AI-driven tokens, prominently focuses on the automation of on-chain activities through autonomous trading agents, abstraction layers, and AI-powered decentralized applications (dApps).
The trend initially gained momentum with the AI agent meta, starting with projects like Goat, born from Andy Ayrey’s Truth Terminal experiment, and the subsequent proliferation of AI agents and frameworks.
The AI agent market reached a peak market capitalization of $17 billion, according to CoinGecko data.
However, while related, the DeFAI sector, valued at just $1 billion according to CoinGecko data, distinguishes itself by fostering a real connection between blockchain and AI.
There is more info here which also makes mention of DePIN (“Decentralized Physical Infrastructure Networks”) and DeSCi (“Decentralized Science”).
Domain Registrations
Just like we saw a ton of ETH .extension registrations back in 2021 there are a bunch of DeFAI .extensions registered this past week. The .com was registered in 2015 and surprisigly the .net was registered just 9 days ago.
DotDB.com shows 144 extensions registered but Whoxy shows 149.
