NFTs: A tool for scammers? Or the pillar of a new digital economy? The quality of the debate on NFTs has been low, plagued with strawman, ad-hominem, and circular arguments. In this thread, I provide a rational framework to develop conviction for or against them. Grab a ☕️

Why I think @solana is likely going to do really well next year: 1. There's going to be 10x-100x more demand for NFTs 2. Solana is the only chain that can support that load

@nikitabier Although I generally agree with taxing inheritance heavily, 100% reliance on it creates really perverse incentives for the government. When your main source of income is not aligned with producing value, but with people dying, imagine the kind of policies they'll prioritize...

> 2. Solana is the only chain that can support that load If you want to give away 1M NFTs, and don't use batching, in Ethereum / Polygon you need to take the full chain's compute power for 9hrs. In Solana, it's a 10th of that (<1hr). And with Firedancer, it will be minutes.

This is a bad, dangerous take. 99% of ppl should not roll their own auth. Risks of doing so are: 1. Distracting you from building your core product 2. Putting your users at risk (auth is one of the most vulnerable areas in app sec) 3. Hurting conversion w suboptimal UX

Blockchain fees (gas/rent) are also a problem. This is the biggest reason why Polygon is currently beating Solana on these projects: Solana is 10x more expensive that polygon. However NFT compression, currently rolling out, will make NFTs in Solana 10x cheaper than even MATIC
