High level summary​

  • Leios prototype development (Treasury Funding Initiative 4: Ouroboros Leios Implementation):
    • Closed an attack on the way nodes announce Endorser Blocks. The attack made honest nodes disconnect from each other (#2179, for ouroboros-leios#1029).
    • db-analyser now reads Leios chains. The tool replays a chain and reports the cost to apply each block. The reports now cover the transactions of each certified Endorser Block, their total size, and the time to read them (#2181, for ouroboros-leios#1023).
  • Maintenance and support (Treasury Funding Initiative 17: Maintenance and Support):
    • Forward-ported the new snapshot interval and the mempool allocation fix from the 4.x release line to the main development branch. The 2026-08-11 update describes both changes (#2209, #2215).
