lion VS iele-semantics

I've been starting to dabble with digital logic design via Clash (https://clash-lang.org/), and there is a very cool-looking RISC-V SoC project done in that tool that looks fairly serious: https://github.com/standardsemiconductor/lion.

That’s fascinating about the M1. In retrospect it seems like kind of a no-brainer but I doubt I would have thought of it.

SPARC had different memory models at different ISA revs IIRC: it’s been like 20 years since I was dealing with SPARC so I might be misremembering the details. Alpha would have been a better example.

RISC-V is really interesting. I’ve been slowly working through this: https://github.com/standardsemiconductor/lion, highly recommend!

Interesting. Actually, you may be just the person to answer my question: Is it possible/plausible to run a Cardano node on Lion OS on a RISC-V machine? IMO, it would be great for the community if we could run all Cardano stake pools on end to end formally verified machines using open source core and hardware.

In addition, you can actually set the riscv-formal suite to verify correctness by k-induction: https://github.com/SymbioticEDA/riscv-formal/pull/28 https://symbiyosys.readthedocs.io/en/latest/quickstart.html#beyond-bounded-model-checks although I concur that by looking at https://github.com/standardsemiconductor/lion/blob/main/lion-formal/app/Main.hs the lion core is only verified with BMC.

There hasn't been any development in that projects github in almost two years. Was that a prototype? Has that functionality been shelved? What am I missing?

The only parts that have yet to emerge are RINA, IELE, Scaling, and the Governance parts of the project. From what I can tell, scaling is 10-25% complete, IELE/K framework is at least 50% done, RINA might be impossible with internet's hardware, and Governance is being iterated upon with each catalyst proposal..let's say 45% finished.

It's still being actively developed and you can follow the development of IELE here: https://github.com/runtimeverification/iele-semantics/ . Since Cardano is a UTXO-based blockchain, it would need to run in an accounting-style sidechain (which is still an active area of research for POS blockchains)

Wait for the "ocean" of languages that will be introduced to Cardano via iele-semantics - meaning one day I will be able to code smart contracts in Python.
