Aptos $APT has just activated the Encrypted Mempool on mainnet, an option that encrypts transaction contents while validators order them. They are only decrypted once the block is finalized.

The mechanism uses the same set of validators that already produces the blocks, without adding an external committee. For institutions and AI agents moving large orders, it reduces exposure to bots that read the mempool.

Gas costs increase, and there are a few extra milliseconds of latency. How practical is it when the market moves fast?
