I just make @Filips course in EOS . I learned that persistant memory has to be payed…but it is some how time limited. In Etherium I can persist small data on chain, like IPFS hashes. Is this also possible in EOS ? Persist something forever ?
best regards
Erhard
Hey @Erhard, hope you are well.
I found this article which i think will explain in detail the persistent storages options for EOSIO, maybe you wanna take a look
