Aptos Launches Encrypted Mempool on Mainnet, Hiding Trade Instructions Until Ordering
- —AIP-144 splits the process into three stages: payload encryption at submission, ordering, and decryption with execution
- —Validators jointly generate encryption keys per epoch; decryption requires stake-weighted shares rather than a single validator
- —Additional latency is roughly 20 milliseconds per block in 50-node benchmarks
- —Supported in the TypeScript SDK from version 7.0.0; no changes to existing Move contracts
Why it matters: The encrypted mempool reduces MEV exposure on Aptos, but it does not guarantee better execution prices or make accounts anonymous.
