there is a Bill functionality in my DApp, which need gather millions of EOS action data to make up a token transfer data for front end to display.
the question is, it takes quite a long time. if it is executed in client side, every time the user refresh, the Dapp regathers again and again.
so I wanna establish a server to do the stuff, but as we know , DApp is decentralized, it bases on chain, not on traditional backend. idk whether it is ok to do so.
need advice, thanks.
