I am looking for a tool that can read the blockchain and:
- Runs on my own server using the blockchain/p2p network for input
- Quickly return the balance for any address
- Quickly send a payment from any private key
Your use case might be a fit for the modular server implementation you see in my footer.
Lets discuss what you need, so I create support for.
BTW: Running the bitsofproof server gives you a normalized relational dstabase of the blockchain, sobalances can be queried via SQL. I also consider to add pruned view of unspent output.
