Hi

Thanks for writing this library. I'm using it to create a test Bitcoin payment channel server, and I'd really like to keep the terminal output clean, so I'd love it if you could make this optional:

By the way, I have written some code for a couple of additional RPC calls. The code is in my repo: master...runeksvendsen:master
Let me know if you want me to create a pull request. I haven't added tests for the calls, and currently don't plan to, but I haven't experienced any issues yet, except internal errors from bitcoind when I forget to limit the number of QuickCheck test runs, and accidentally spam it with 100 transactions in a second.

Hi, thanks for your work on this library. I created a simple demo using the bitcoin-api package, and based off https://github.com/solatis/haskell-bitcoin-api/blob/master/test/Network/Bitcoin/Api/WalletSpec.hs, the demo is https://github.com/ketzacoatl/btc-monitor/blob/master/src/Main.hs. It compiles just fine, but at runtime I get this funny error I don't know what to do about:

Now sending JSON command: "{\"jsonrpc\":\"2.0\",\"params\":[\"mywallet\"],\"method\":\"getaccount\",\"id\":1}"
Now sending JSON command: "{\"jsonrpc\":\"2.0\",\"params\":[1,false],\"method\":\"listaccounts\",\"id\":1}"
Now sending JSON command: "{\"jsonrpc\":\"2.0\",\"params\":[],\"method\":\"getinfo\",\"id\":1}"
btc-trx-monitor: JSONError "Error in $.result.balance: expected Integer, encountered floating number 1.3"

This 1.3 is coming from bitcoind when I query a real wallet that has BTC in it from a faucet (this is on the testnet).

Am I doing something wrong, or is there an error in the library? When I review the test specs, I'm not sure I see coverage for floating point numbers.

    Perhaps you meant ‘Btc._blockTxns’ (imported from Data.Bitcoin.Block)
