Yes, thanks. I've edited the original for clarity. -gt-

Okay, for anyone who has been following this, I FINALLY got it completely solved. The sixth field is indeed used in computing the block hash. It turns out this is actually a well know addition to stratum mining - but I…

Thanks for that information. I imagine an Antminer cannot just choose arbitrarily to use this "if it feels like it" because the only way the pool can reconstruct the block header is if there is agreement on how it is…

I’ve got a question about that last part in my mining.submit JSON right after the Nonce (the "09b66000"). "1AGf9v4rYBSAnMXi8rvE6nxutC5ZoaVfNa.425" // Miner ID "3782626", // Job ID "ec100000000000", // Extranonce2…

In case anyone still cares about this post, I should mention that I FINALLY go the thing 100% solved. After wondering about the extra "sixth field" that the miner was submitting after the usual five fields that are…

Well, apparently it is not that easy. I STILL cannot produce a decent hash. I've been working with an older version of cgminer that supports BTC mining, and I've written a program to act as a fake pool which serves up…

Well, here's an update for anyone who cares. I now FINALLY have all the bits and pieces I need to sort this out. From greg's "learn me a bit coin" website, I found an example of everything EXCEPT the coinbase value.…

Hello, sdfasdf I had a look at the URL you sent. I note that the author includes a commented out test "blockheader" and he is hashing it correctly. I know this for two reasons, i), the hash value obtained makes sense,…

Yes, thanks, Cricktor. Of all the source information I was able to find, this one (which I already knew about) came the closest to solving my troubles. It filled in a lot of holes, but still lacks a 100% completely…

I've been searching for two weeks for a detailed breakdown of how to hash the block header, but nothing covers the entire process. So I figured I'd reach out here for some help. I'm coding for BTC mining using a CPU. I…
