Is a merge of the two networks a possibility? Main net has increased to 3.1Ph/s and Jtoomim to 7.6Ph/s. A combined 10.7Ph/s would be good to see and may help attract more to the pool.
The 3 PH/s spike on mainnet is over. It was probably just someone renting on Nicehash for an hour or so. Mainnet is back to ~1 PH/s.
It is not possible to "merge" the two networks. They are separate share chains. What is possible is for people to switch chains so that everyone is on the same chain.
Also the mainnet reward is much more often in line with jtoomim these days. Presumably some development has taken place there...?
No, it's not. At this particular moment, I see:
16.72565364 BTC/block on mainnet in 1681 transactions
17.48822478 BTC/block on jtoomimnet in 2026 transactions
You have to look at the actual shares being mined to see the difference. The "Current block value" metric on a node's front page shows the value before mainnet's transaction trimming takes place.
Something to keep in mind is that the bug/design flaw on mainnet that forces small blocks is intermittent. It shows up when a Bitcoin block has been recently published, and disappears a few minutes later. Just because they show the same thing at one moment doesn't mean it will always be the same.
Is is possible to run P2Pool on 64bit versions of Python, etc??
Both 32 bit and 64 bit versions of Python should work. I don't think I've tested with 32 bit versions before, though.
