Sigma

  • Security issue identified in Sigma thanks to a responsible disclosure via our bug bounty system (many thanks to the researcher who reached out to us). Patched with no incident. New release 13.8.8 incoming today. (13.8.6 and 13.8.7 were internal releases)
  • Sigma will be re-enabled  past block 220720 which is around December 5th.
  • Final testing of sigma verification and proving improvements which now have multi-threading support with huge improvements in syncing speed and also multi-spend proving for multi-threaded systems. #776

Lelantus

  • Draft paper on hierarchical 1-out-of-many Proofs completed and submitted for peer review.
  • This new construction can reduce proof generations times and allow for more efficient batch verification at the cost of slightly larger proofs.
  • Helping Monero Research Labs review Triptych to also see if there are any techniques that can be used to improve Lelantus

Mnemonic Support

  • New wallets created will have full mnemonic seed backup support (including for Sigma mints) #641
