hey guys! just wanted to know what you guys think about bringing ebpf to the polkadot ecosystem. for those who don’t know, solana uses ebpf runtime in the userland to execute their smart contracts. the reason why i like their execution model is because of the program verification done by the ebpf r…

I’d be keen to see a parachain bringing this to the ecosystem.

What a coincidence. @pepyakin and me did a hackathon last week with exactly this subject. We ported pallet-contracts to to accept eBPF contracts to see if it is viable to support this bytecode. It isn’t Solana compatible but uses the pallet-contracts API. We got a proof of concept working. There wi…

[image] abhi: the reason why i like their execution model is because of the program verification done by the ebpf runtime before it is executed. @abhi , could you explain more about this? I tried searching but couldn’t find a good explanation of what kind of verification is being done.

I think what they are talking about here is the static verification that the kernel uses to elide gas metering and bound checks. However, Solana uses a modified eBPF which is turing complete and does all of this at runtime. So this doesn’t really apply here. Using the original eBPF would be a real …

@Alex thanks for explaining. [image] Alex: PITA What does that stand for?

Urban Dictionary: PITA P.I.T.A is an acronym that stands for Pain In The Ass
