I'm trying to figure out how I'd submit a block in many alt-coins. I originally found this issue in bbqcoin but have since found it in many others. I have bbqcoin (and others) installed from gihub source on Ubuntu 12.04.4

Best I can figure, the closest thing would be sendrawtx.. but that can't be right, can it? I'm thinking at this point I should have taken advantage of the checkout feature, but it's hard to tell what version each coin is on.

Edit: I've found that many coins have this issue as described here: https://github.com/Crypto-Expert/stratum-mining/issues/72

So looks like the solution is to build it yourself, there is a hail-mary workaround which might do the trick but is heavily undocumented. I found reference that you can submit a block through getblocktemplate, https://github.com/moopless/stratum-mining-litecoin/issues/48

When trying with some data I go a json parse error.. has anyone used getblocktemplate submit?
