On Monday, Aptos Labs announced via X that Encrypted Mempool is now live on the Aptos mainnet.
With this feature, users can opt in to keep pending transactions encrypted until their block is finalized, lowering the risk of MEV attacks.
Other benefits include;
-
Opt-in, one transaction at a time
-
The function called, and its inputs stay encrypted until execution
-
Senders and fees remain visible
By default, pending transactions are public before they execute, on Aptos and most other chains. Anyone watching can see the details and trade against them.
Encrypted Mempool adds a choice. For transactions that opt in, the validators that order each block are the same ones that decrypt it, and no single validator can decrypt them alone. The option is built into the protocol itself.
Aptos is a scalable layer-1 blockchain based on the Move programming language. APT is the project's native token.
Aptos is a Layer 1 Proof-of-Stake (PoS) blockchain that employs a novel smart contract programming language called Move, a Rust-based programming language that was independently developed by Meta (formerly Facebook)’s Diem blockchain engineers.
Aptos’s vision is a blockchain that brings mainstream adoption to web3 and empowers an ecosystem of DApps to solve real-world user problems.
The PoS blockchain can achieve a theoretical transaction throughput of over 150,000 transactions per second (tps) through parallel execution.
In March 2022, Aptos raised $200 million in a seed round led by the venture capital firm Andreessen Horowitz (a16z). Other crypto heavyweights like Tiger Global and Multicoin Capital took part in the funding round.
Fast forward to July, the startup raised another $200 million in a Series A round with participation from Dragonfly, Apollo Global, Franklin Templeton, Animoca, Jump Crypto, and others.
APT is down 4.3%, trading at $0.8553 per coin. For a start, the Aptos team claims that its network can process over 150,000 TPS. By comparison, Ethereum’s mainnet TPS is around 12 to 15.
This high transaction throughput is enabled by a parallel execution engine (Block-STM)—a Byzantine fault-tolerant (BFT) PoS consensus mechanism. For context, most blockchains execute transactions sequentially, which means that a single failed transaction or high network demand could hold up the entire chain.
