Is pg_credereum still mantained?

[ROBERT-MCDOWELL]

Hi,

does it work with PG 12.3?
I'm looking for an extension to start a blockchain project public/private and want to integrate postgresql.
thanks

hello there, is this project dead? I want to know as I would like to fork and use it thanks

btw, I tried to compile it with postgresql 13 and got compile error:
