Aptos Labs Proposes Encrypted Mempool for Aptos (APT) With 27ms Latency Cost

Aptos validators would take on a new duty under a proposal from Aptos Labs: hold pending trade instructions in encrypted form until transaction ordering is complete, then reveal the sealed payloads for execution.

The design, set out in the team's official blog post on October 30, 2025, would let pending APT trades remain hidden until ordering completes. This addition comes with a measured cost of 27ms latency in tests while awaiting a governance vote.
