Peter Rizun spoke at BLISS about his ideas for a RISC-V system in BCH, potentially run in parallel to and eventually maybe even replacing Bitcoin script. Pretty radical change & suggestion, but might have enormous benefits.
Note that Vitalik also suggested moving the ETH EVM to RISC-V not even a month ago too, as Peter references in his talk.
Need a thread to monitor and discuss this trend in the industry as it plays out.
