Aptos ships native encrypted mempool as four-year vesting ends

Aptos has turned on an optional encrypted mempool on its mainnet, letting users hide a transaction’s contents until a block is finalized. The feature is expected to defend against front-running, and it went live on the same day that the Aptos network’s four-year token unlock schedule came to an end. Aptos has added an optional encrypted mempool to its network, and it’s aimed at traders. Users can now hide which function their transaction calls and what inputs it uses. The feature comes from Aptos Improvement Proposal 144 (AIP-144), written by Aptos Labs cryptographer Rex Fernando.
