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.


Have a look at Bitpays bitcore: https://bitcore.io/guides

Edit October 2018: this software is no longer reliable.

  • It seems to not be supported anymore. The last update is 0.12.1 version from last year...

  • I guess stopping at 0.12.1 was done intentionally. But not sure. Jun 5, 2017 at 8:25
  • I wouldn't recommend anyone use that software: it's unmaintained and unreliable.
