Blockchain Security - MEV (Miner Extractable Value) is a persistent issue, with approximately $300 thousand lost to sandwich attacks last month [1] - Threshold encryption offers protection by encrypting the mempool, hiding transactions until block inclusion [1] - Shutter pioneered threshold encryption, initially with per-epoch encryption, later improved to per-transaction encryption, now live on Gnosis Chain [1] Vulnerabilities - A critical flaw was revealed: when the epoch key was reconstructed, all transactions became public, including those not yet included in the block [2]

Solana Ecosystem Improvement - Addresses three major critiques: extractive sandwich attacks, institutional sequencing control, and onchain CLOB building difficulties [1] - Introduces a solution that tackles all three issues simultaneously [1] Key Technological Advancements - Implements a private encrypted mempool to prevent sandwich attacks [1] - Enables app-specific sequencing for building onchain CLOBs [1] - Provides verifiable ordering, allowing institutions to build without MEV concerns [1] - Improves transaction landing efficiency [1] Industry Impact - Represents a significant change in Solana's history [1]

RT chris (@chrischang43)1/7 Almost a month has passed since epoch 805.Sharing the latest sandwich <-> validator data for epoch 819@MarinadeFinance removed the worst offenders from their stake pools, which has had a significant impact in reducing sandwich attacks on Solana https://t.co/7gUbXYmUQb ...
