Comment on Proton Now Has a Bitcoin Wallet

Until homeomorphic encryption becomes a thing, cloud can’t be secure or private.
every exchange I’ve looked at holds the keys to your account
Exchanges, are not wallets. You’re supposed to move the coins out of the exchange for safekeeping. If you can’t, then it’s not a crypto exchange, it’s an ETF peddler.
how a user can actually buy bitcoin using Proton Wallet.
Wallets, are not exchanges. They can link to exchanges, like Metamask does, but their core function is to hold your keys.

Why do you need homeomorphic encryption? Isn’t client-side encryption good enough for most use cases?

Yes. Homomorphic encryption is for data processing, not data storage.

I am aware. What processing is only possible in the cloud, and not locally?

Client-side is not cloud.
Yes, you can keep client-side reasonably secure. You can’t send the data for cloud processing and seriously expect much security or privacy… for now. Encrypt client-side and use cloud as storage… maybe; encryption algorithms also have a “best by” date.
