Aptos has a proposal for an encrypted mempool that would keep pending trade instructions hidden until transaction ordering is finished, and tests showed 27 milliseconds of added proposal-to-execution latency. Separate governance coverage shows Proposal No. 206 had nearly unanimous support, but turnout was only 2.69% against a 24.8% quorum requirement, with voting set to end on Oct. 6.

What it means

Who it affects, what changes and what is still unconfirmed

Each sentence links inside to the piece that supports it.

Users and traders on Aptos are the ones who would notice the proposal most directly, because the design would keep pending trade instructions hidden until ordering is complete. The lab’s test result also puts a concrete number on the added delay in that process: 27 milliseconds.

In practice, the proposal changes what can be seen before ordering is complete, while the governance process around it still follows the existing vote-and-quorum structure. Proposal No. 206 already had nearly unanimous support, but the turnout figure was still below the quorum threshold named in the vote update.
