A Practical Approach to Multi-Concurrent Proposers
summary
Proposes a sequencer-driven decoupled state machine replication that assigns each account to one out‑of‑protocol sequencer per epoch, preventing duplicate submissions and fund‑exhaustion waste that collapse throughput in multi‑concurrent proposers. Implements an m‑of‑n inclusion rule requiring m‑of‑n certificates of sequencer references to validate blocks, shifting fee guarantees and ordering to sequencers so fee‑paying TPS approaches block limit × concurrent leaders without the duplicate/failure losses. Tradeoffs: reduced generality and reliance on sequencer selection, but simpler and deployable now.
