In 2026, on-chain privacy will move from theory to practice, with experts predicting a shift towards more pragmatic and industrialized solutions. Bobbin Threadbare of Miden predicts that binary privacy models will be abandoned in favor of conditional privacy for high-risk transactions. Khushi Wadhwa of Predicate forecasts that private and compliant stablecoins will rise to become the core payment layer. Paul Brody of Ernst & Young expects that various privacy solutions such as Aztec and Railgun will be deployed from testnets to production environments, but scalability challenges will still remain. Wei Dai of 1kx predicts that "threat-resistant" privacy combining rate limiting and responsible solutions will become the new default, preventing abuse while ensuring the security of on-chain activities.
