Many blockchain applications require democratic on-chain decision-making. In this work, we propose a community-inclusive decentralised collaborative decision-making system with privacy assurance. Its key component is two-stage voting scheme inspired by choice architecture. Our compatible most existing infrastructures. addition, it supports liquid democracy/delegative for better intelligence. Na...

Privacy-preserving data aggregation in wireless sensor networks (WSNs) with mobile nodes is a challenging problem, as an accurate aggregation result should be derived in a privacy-preserving manner, under the condition that nodes are mobile and have no pre-specified keys for cryptographic operations. In this paper, we focus on the SUM aggregation function and propose two privacy-preserving data...

In this paper we solve the open problem, finding the solutions for privacy-preserving horizontally partitioned linear programs with inequality constraints, proposed recently by Mangasarian, O.L. ( Privacy-preserving horizontally partitioned linear programs, Optim Lett 2011, to appear).
