agree grin Conference(or grin guang zhou meetup).
grin Conference ,which Let others know that the project is still alive,should be held every two years.The source of funds is mainly self-funded, and fundraising is secondary
I think Grin should have a presence at a Proof of Work conference. @oryhp was this the one that you were looking at before? https://powsummit.com/ I bet the CC could fund someone to give a technical presentation at some point. (Handing out shirts could be cool too Where is the Grin “no” list? - #33 by trab ) Old school people might be pleasantly surprised to see Grin is still kicking.
I also think a really good talk could be on the subject of how Grin compares to Lightning specifically and not just Bitcoin. Seeing as how Lightning is also fully interactive, has had attempts to make “vouchers” like slatepacks, and attempts to add privacy.
