L2BEAT launches a privacy protocol ranking feature that evaluates adversary models across five threat vectors.
Tech & Launches ·
L2BEAT released a new feature that ranks privacy protocols against five distinct adversary models, addressing the question of who each protocol protects data from. The tool evaluates 11 protocols across three privacy dimensions—link privacy, amount privacy, and recipient privacy—then tests each against public observers, chain analysts, network observers, protocol insiders, and hypothetical future adversaries with advanced capabilities. The assessment uses color coding: green indicates a careful user can defeat the adversary using only the protocol's supported options, yellow signals a leak or reliance on unsupported workarounds, and red means the protocol offers no defense.
Only two protocols—Tornado Cash and Railgun—achieved green ratings across all five adversary types as of the September 2026 feature launch. Tornado Cash holds 745.77 million dollars in total value locked, while Railgun holds 97.75 million dollars. The privileged insider threat proved the widest weakness, breaking seven of the remaining nine protocols. Other tracked protocols include Zama Confidential Tokens, Privacy Pools, STRK-20, Privacy Boost, Umbra Cash, Payy, Cloaked, Fluidkey, and Zcash via NEAR Intents, each with varying TVL and privacy guarantees.
The feature launched with a dedicated summary page showing TVL data tracked over the prior twelve months alongside deposit and withdrawal counts, though the underlying assumptions driving each protocol's threat-model assessment and the mechanisms by which users might defeat each adversary class remain to be fully detailed.
