This brings me back! During the second year of my bachelor's we had a group project on distributed systems, we basically had to create a blockchain with primecoin PoW, written in service oriented programming language developed at the university of Bologna called Jolie (https://www.jolie-lang.org/)
Interesting!
Does anyone know other innovative PoW chains?
Monero's RandomX is an interesting PoW scheme one designed to be optimized for CPUs. Here is an interesting read about its design https://github.com/tevador/RandomX/blob/master/doc/design.md
Chia uses a very memory-hard PoW system and is usually mined on SSDs.
I've seen a lot of "useful PoW" cryptocurrencies, but they tend to not pan out. For example Gridcoin is just a Proof-of-Stake cryptocurrency with a program that hands out GRC to BOINC contributors.
If you wonder about its financial value, its market cap is around $ 2.5m [1].
