This is a curious post. There is apparently a Settle Network and a github repo. But S. Spolu is not listed among the execs running it.

I see a link to https://settle.network which isn't the same as https://settlenetwork.com
Edit: The "settle.network" domain as it sits now was first registered in 2019, well after the last activity on the github repo. So yeah, he let the domain lapse out.
