Alternative ordering in subnet applications (22Q2 brainstorming)

[jsoares]

• HC subnets for consensus-less payments (preferably in-house)
• Matej’s work and follow-ups
  • We’re doing some (theoretical) research on that w/ P. Kuznetsov and YA. Pignolet in case you are interested :)
  • Sui from Mysten Labs is creating a mixed consensus/consensusless blockchain
• GNU Taler
• Asynchronous BFT replication systems with relaxed/mixed (other than total-order) consistency in execute-then-order model (STM-like semantics with VM assistance?)
