buying a stock on web2 vs web3 gives interesting properties because of ownership.
for ex: take an instant USD loan on your stock, since you are the owner only your authority(signature) is needed. In web2 world you go through middlemen.
there is practically no attack vector in using infura.
Infura can't fake your can't fake your cryptographic signature. Worst case, they censor txs from your address at which point you can run your own node.
I'm not even talking about an attack vector. I'm talking about a centralized system that is recommended by other developers when Ethereum keeps on making claims of moving forward centralized systems.
If you are an optimist, HN is not the right place to have a "pro" discussion imo. I will outline products that i'm most excited about or use regularly .
2. Stablecoins, especially USDC. I get paid for my consulting in USD from US to India with a tx fee of $0.00025 on Solana. I'm saving a lot compared to using PP/Payoneer.
3. Supporting artists I love with NFT on foundation/ opensea/magic eden(for some reason I never did this before although there are web2 sites for it).
4. Generate yield on your stable coins. I wont mention apps here since they are new and have some smart contract risks to it, DYOR.
5. Creator monetisation using unlock-protocol.com and mirror.xyz.
6. Play to earn models in games(Axie infinity and Aurory).
7. Internet native experiments on inclusive sybil resistant identities(proofofhumanity.id)
"Legitimacy is a pattern of higher-order acceptance. An outcome in some social context is legitimate if the people in that social context broadly accept and play their part in enacting that outcome, and each individual person does so because they expect everyone else to do the same."
