Description
Distributed Blockbuilding is a HashCloak research project conducted in collaboration with Flashbots. It studies practical construction of distributed blockbuilders, combining privacy-enhancing technologies, advanced cryptography, algorithmic game theory, and cooperative game theory to address builder incentives, coalition defection, cheat-proof mechanisms, and ecosystem tradeoffs in MEV-related blockbuilding.Category: Uncategorized
Publicly Verifiable & Private Collaborative ML Model Training
Project Links
Description
HashCloak's R&D project explores publicly verifiable computation over private shared state through a privacy-preserving logistic-regression training pipeline. It combines TACEO's co-noir framework and a collaborative-SNARKs backend with fixed-point arithmetic and polynomial sigmoid approximations, demonstrating simulated three-party MPC training on commodity hardware.Category: Uncategorized
