Currently the full node can offer details of transactions sitting in a queried block but it is not possible for it to provide infos on a particular transaction from its hash because the native tezos DB does not build an index based on transactions hash.
What are the options available to build such an index ? Ocaml pro has open sourced TzScan code but has anyone actually given it a go and been able to reconstruct its db ?
Is there other solutions which people have been experimenting with ?
