This paper introduces Flamingo, a system for secure aggregation of data across a large set
of clients. In secure aggregation, a server sums up the private inputs of clients and obtains …

In this whitepaper, we articulate a vision for the evolution of Chainlink beyond its initial
conception in the original Chainlink whitepaper. We foresee an increasingly expansive role …

We present a new succinct zero knowledge argument scheme for layered arithmetic circuits
without trusted setup. The prover time is O (C+ nlogn) and the proof size is O (D logC+ log 2 …

We present CanDID, a platform for practical, user-friendly realization of decentralized
identity, the idea of empowering end users with management of their own credentials. While …

Blockchains are gaining traction and acceptance, not just for cryptocurrencies, but
increasingly as an architecture for distributed computing. In this work we seek solutions that …

Blockchain is a technology with decentralization and immutability features and has been
employed for auditing by many applications. However, immutability sometimes limits the …

Distributed Key Generation (DKG) is a technique to bootstrap threshold cryptosystems
without a trusted party. DKG is an essential building block to many decentralized protocols …

In this article, we propose SPADE, an encrypted data deduplication scheme that resists
compromised key servers and frees users from the key management problem. Specifically …

Byzantine Fault-Tolerant (BFT) State Machine Replication (SMR) is a classical paradigm for
implementing trustworthy services that has received renewed interest with the emergence of …

Existing approaches to secure multiparty computation (MPC) require all participants to
commit to the entire duration of the protocol. As interest in MPC continues to grow, it is …
