No, no fckn rollups on Bitcoin 😂
zk rollups require newschool cryptography that are not in the spirit of Bitcoin & trusted rollups would require changes to Layer1 to undo transactions which the Bitcoin community would NEVER accept
why not?

I wrote a second paragraph edit to explain. Bitcoin is already scalable through Lightning

Appreciate the added context, and agree that Lightning will help Bitcoin scale too.
Can you point me to any other resources that explain these issues you see with rollups more in depth?
Also curious to hear @lightcoin’s take on the issues you mentioned. He wrote the Bitcoin Rollups research report.

Sources - idk I work in IT/mathematics and have spend a lot of time with zk-proofs such as signatures and hash preimages (their derivatives specifically). I do think they look cryptographically sound for now - but the spirit of Bitcoin has been betting on standard and well established cryptography for a long time. Modern zk-proofs do not have this long history of being unbroken yet
reply
STARK proofs rely on crypto assumptions that are even older than the crypto assumptions bitcoin already relies on (collision-resistant hash vs elliptic curve DLP; see here)
Regarding implementations, there are validity proof implementations that are about the same age as the Schnorr implementation that is used in bitcoin.
