Cairo 0 is felts all the way down. Everything is a felt and developers are viscerally aware of this.
string? felt. array? felt*. u256? felt, felt.

I was curious how much faster "state of the art performance" is than
@CairoLang
"legacy" proof system for zkVM
Ran the numbers:
Fib 10000 on M2 Max:
SP1 8.02s
Cairo w/
@class_lambda
Platinum prover: 2.9s
So SP1 SOA is 2.75x slower 🤔
Imagine with GKR and logup
Cairo still…
3/ SP1 is 100% open-source and achieves state of the art performance on real-world workloads.
Its speed comes from using the latest ZKP research, with a cross-table lookup architecture, a customizable “precompile” system that can accelerate any performance bottleneck, and more.

cairo changes the game
a common misconception is that cairo programs need to be run "onchain"
ultimately, only proof validation needs to be onchain
the prover can be anyone, even your worst enemy
thats the power of computational integrity and what enables massive scalability
What if we just used
@CairoLang
for what it is, a way to generate zk proofs easily, and built software without actually running all of it on-chain.
Ex: P2P game where all players share proofs of play, and the final state is sent on-chain.
Is this an L3 with extra steps?

We'll have over over ten games deployed on Slot next month 👀
