  sech1: have there been any recent-ish changes in the way xmrig/xmrig-proxy/p2pool split the workloads via the top 8 nonce bits?
• 15:06
  merope
  Or perhaps some pool software updates that may have influenced it
• 16:28
  sech1
  no changes
• 16:28
  merope
  Hmmmm
• 16:28
  merope
  The nonce patterns have shifted a little bit, and I'm not sure why

  Could be just from the high difficulty, perhaps

  i can;t access those files :(
• 16:30
  merope
  Oh, I thought they'd get bridged properly
• 16:31
  merope
  One sec, let me upload to imgur
• 16:31
  gingeropolous
  oh wait
• 16:31
  gingeropolous
  they are coming in on matrix now
• 16:31
  gingeropolous
  merope,
• 16:31
  merope
  Ah, perhaps they were still uploading then

  I just saw download URLs here, and they downloaded fine

  this sounds like something sech1 has been monitoring for a while
• 16:33
  merope
  Oh? I thought I was the only one

  a live nonce pattern viewer, like on a website, would be cool
• 16:33
  gingeropolous
  like part of a network monitor
• 16:33
  merope
  it really would

  unfortunately my web dev skills are virtually nonexistant
• 16:34
  merope
  but if anyone knows how to create a pretty interface, I can provide the backend/data to visualize

  "pretty"

  Anyway, the shift seems to have happened around block 2528000-2530000

  P2pool?
• 20:06
  garth
  Is the nonce for P2pool the same for all xmrig mining?
• 20:10
  merope
  Yes, though your question is kinda malformed
• 20:11
  merope
  The block template + nonce used for mining is always in the same format for everyone, because it's strictly defined by the protocol

  sech1: how did you compile the p2pool binary for macOS? it dynamically links to a couple dependencies
• 22:38

  Github CI

  It was compiled on MacOS 10.15
