Bitcoind address index Does anyone know some reliable Bitcoind fork which allows to use address index?
I know that there are 
 https://github.com/bitpay/bitcoin and
 https://github.com/btcdrak/bitcoin/releases

But is seems that there are not supported any more.

What I really need, it is getting unspend outputs for any address (not for the wallet only), and it need to work fast(max 1-5s).
The scantxoutset RPC in 0.17+ will do what you want, although unless you batch query several addresses at once it may be a bit slower than what you were asking for.
