Since the last research update, IC3 researchers exposed copyright vulnerabilities in current NFT designs, made progress in solving the Selfish Mining problem, designed a system for fair NFT drops, and more!
IC3 researchers examined the mismatch in current NFT practices between copyright law, community expectations, and largely unenforceable current implementations.

The authors present a simple and concretely efficient asynchronous DKG (ADKG) protocol.

The authors present an approach for compressing hash-based signatures using STARKs. Their constructions are directly applicable as scalable solutions for post-quantum secure blockchains

The authors present Colordag, a novel protocol that is an epsilon-sure equilibrium. 
By epsilon-sure equilibrium, they mean that with arbitrarily high probability good behavior is a strict best response. This work provides significant progress in solving the Selfish Mining problem.

The authors present the Filecoin Hierarchical Consensus framework, which aims to overcome the throughput challenges of blockchain consensus by horizontally scaling the network using subnets.

IC3 researchers designed a system for fair NFT drops using CanDID and demoed the system in the ETH Denver Hackathon with a fair drop raffle for a piece of NFT artwork by Zach Lieberman.
