Aptos has introduced a proposal for a native encrypted mempool system designed to protect users from frontrunning, censorship, and transaction order manipulation while maintaining network speed and transparency.
If approved through governance, Aptos said the feature would make it the first Layer 1 blockchain to provide built in encrypted transaction submission directly at the protocol level.
The proposed system would allow users to submit transactions privately with a single click while ensuring that full transaction details remain publicly accessible onchain after block confirmation.
Aptos Seeks to Reduce MEV Exploitation
According to Aptos, the upgrade arrives as decentralized exchange activity continues expanding rapidly across the crypto market.
The company noted that decentralized exchange spot trading volumes consistently exceeded $200 billion per month throughout 2025 and averaged approximately $476 billion monthly during the third quarter.
Although decentralized exchanges removed dependence on centralized custody and settlement systems, Aptos pointed out that most blockchain networks still expose pending transactions before they are finalized.
This visibility enables validators and other network participants to monitor trading activity and potentially exploit transactions before execution.
Aptos explained that this environment has fueled the growth of the maximal extractable value market, commonly known as MEV, where validators and traders profit by reordering, censoring, or exploiting pending transactions.
The proposed encrypted mempool aims to eliminate this exposure by keeping transaction intent hidden until execution while preserving the network’s existing security model.
How the Encrypted Mempool Works
Aptos Labs explained that the system relies on threshold cryptography combined with a distributed key generation process that occurs before every validator epoch.
Under the proposed design, transactions are submitted as encrypted payloads, and validators collectively decrypt them only after a block has already been ordered.
The company noted that traditional encrypted transaction systems often struggle with scalability because validators must individually communicate and process partial decryptions for each transaction. This creates significant communication overhead, computational strain, and increased network latency.
To address these limitations, Aptos researchers developed a batched threshold decryption system that enables validators to generate a single partial decryption for an entire group of encrypted transactions instead of processing them separately.
According to Aptos, this method dramatically lowers communication and computation costs while allowing much of the processing work to be completed ahead of time.
The company also stated that the system is designed to prevent replay attacks, remove the need for users to compete for encryption access, and eliminate repeated transaction submissions.
Aptos added that the encrypted mempool integrates directly with the network’s consensus protocol while introducing only minimal additional latency.
APT Token Sees Strong Monthly Growth Despite Minor Pullback
Aptos’ native token, APT, has recorded steady gains over the past month, climbing from around $0.82 in mid April to nearly $1.10 by mid May.
During the rally, the token briefly surged above the $1.20 level before retreating slightly.
Over the last 24 hours, however, APT declined by nearly 2 percent and was trading close to the $1.10 mark at the time of writing.#crypto#cryptonews https://coinsignals.net https://t.me/coinsignalpublic
