SnarkPack: Practical SNARK aggregation
Zero-knowledge SNARKs (zk-SNARKs) are non-interactive proof systems with short and efficiently verifiable proofs. zk-SNARKs are widely used in decentralised systems to address privacy and scalability concerns. One of the main applications is the blockchain, were SNARKs are used to prove computations with private inputs and reduce on-chain footprint verification and transaction sizes.

Increasing software update security through PGP-compatible threshold signatures
Increasing software update security through PGP-compatible threshold signatures Whether we are aware of them or not, software updates and the systems that support them permeate the current software landscape. Given their pervasiveness, it should come as a surprise that software created to manage such updates, broadly referred to as package managers, still pose security concerns.
