On-chain PrivacyOct 15, 2026
Why privacy coins may not be enough to protect on-chain trading strategies
A PANews-translated article argues that renewed interest in on-chain privacy goes well beyond a niche cypherpunk theme. In a market where public ledgers expose wallet balances, trading habits, venue preferences and even activity patterns, the piece says privacy tools that only hide value transfer fail to protect the parts traders care about most: intent, trigger conditions, timing and execution parameters.
The article reviews existing approaches across dark pool trading and spot execution. It cites Renegade, which uses MPC for matching and zero-knowledge proofs for on-chain verification, Aster’s hidden orders and hidden positions, private RPC systems such as Flashbots Protect and MEV Blocker, and Shutter’s threshold-encrypted mempool. In the author’s view, each tool helps at one stage of the trading lifecycle, but none provides a general privacy layer for programmable strategies.
The report then focuses on Nillion’s proposed primitive, Covenants, described as sealed "if-this-then-that" instructions that remain hidden until preset conditions are met. It says the first implementation under the project’s "Dusk" phase is planned for Ethereum mainnet, with later stages extending to multiple chains, external data sources and more complex private logic. The article also points to use cases including sealed-bid auctions, protocol safeguards, private conditional orders and cross-chain triggers, while presenting Covenants as part of a broader push toward what it calls "encrypted markets."
