Last year, I wrote a @Cointelegraph research article on Batched Threshold Encryption (BTE) and how it could help reduce malicious MEV on Ethereum. Going through the article again, I though to share here as well. For context, on public mempools, anyone can see your transaction before it is included in a block on the blockchain. Bad actors use that window to jump ahead of your trade and profit at your expense. To solve this, Encrypted mempools was developed. It can hide transactions by encryption until they are decrypted by the right person (server) to be included in a block. The standard way to do this is to split a decryption key across multiple servers. Each server must decrypt every transaction one by one and post its piece of the answer onchain at the right time. But that gets expensive very fast. BTE helps reduce this cost because it requires servers to agree on a shared mathematical curve and use it to release one small piece of data that unlocks every transaction in the batch at once. The original BTE design came out in 2024. Since then, three successive designs, one-time setup BTE, BEAT-MEV, and BEAST-MEV, have each removed a different coordination bottleneck. BEAST-MEV now decrypts batches of 512 transactions in under one second with no coordination required between servers beforehand. My article traces the full progression of BTE and explains why L2s like Espresso and Radius are the most natural early adopters if BTE can be enshrined on Ethereum.
