Polkadot JAM is built on the PVM ISA and it uses an entirely custom instruction set. Last week we announced PVM2 , a re-imagination of the PVM ISA towards standard RISC-V. Our exploration work showed the following: A custom instruction set like PVM is not necessary. We can get competitive performanc…

Blows me away that no developers is interacting with your threads, regardless of their believes… what you are doing is a net positive to the ecosystem, and i highly support the conversation.

Blows me away that no developers is interacting with your threads Probably just in the closed circle here. Our Matrix room is quite active: https://matrix.to/#/#jar:matrix.org And we actually also have interests from existing JAM implementation teams. Of course, before they receive JAM Prize an…

are original and current PolkaVM developers interacting with you on Element? I dont use that platform but I think it is PARAMOUNT that they have a healthy dicussion on what you are exposing here.

Honestly, we have stopped directly comparing with PolkaVM because it’s just slow in our charts. Our development process also revealed a lot of situations where PolkaVM just only publishes benchmarks that favor themselves, and tries to “cheat” on others. (Check the repository for all the specific per…

@sorpaas I’ve been following your publications from a distance. I cannot say I’m fully on top of it all, but with all due respect, I find it really hard to understand why you insist on proceeding with your work within the Polkadot ecosystem and community in a way that seems to work against your own …

We checked legal and we’re actually fully within our rights to name it PVM2. We aren’t referring to PolkaVM. By the way, we want to note that PolkaVM itself has a trademark violation of RISC-V – it’s a non-conformant implementation, and RISC-V International has been pretty clear that you cannot use…

[image] kukabi: In short, I’d like to ask, not rhetorically but genuinely out of curiosity, why are you doing this? For the rest of your questions: yes, we’re doing this deliberately. Our intention posting in this forum is that Polkadot should have a choice. JAR and JAM are both protocols. Co…

I think we have all been in the sidelines on this, I applaud the effort, but the communication tone is hard to take, I agree with You and think the ecosystem would benefit from having this kinds of efforts. Decentralization is max friction and when it comes to techs challenging the status quo, triba…

Moderator note: General reminder to everyone: technical disagreement and criticism are welcome, but please keep the discussion focused on the claims, benchmarks, design choices, and tradeoffs. Avoid speculating about motives, intentions, good faith, or personal character. Let’s keep this thread cons…
