Aptos said it plans to launch a native encrypted mempool (holding area for pending transactions), subject to governance approval. The blockchain project said the feature would make Aptos the first Layer 1 blockchain (base blockchain network) to offer full confidentiality for transaction intent, while maintaining network speed. In practice, an encrypted mempool is intended to prevent pending transaction details from being openly visible before execution, a design often aimed at improving privacy and limiting information leakage in blockchain trading and transaction processing.
