Polyhedra’s ZK Prover Tops Speed Rankings in First Proof Arena Results

Polyhedra Network, a blockchain project focused on zero-knowledge (ZK) proofs, has released the first set of data from its new Proof Arena, a benchmarking platform designed to evaluate and compare different ZK provers.

According to the team, "The data includes comparisons of provers from Polyhedra, Polygon, Linea and StarkWare – Expander, Plonky3, GNARK, Halo2 respectively. Results: the Expander prover is significantly faster in terms of proof generation time and peak memory; Plonky3 achieves stellar performance in terms of setup and verification time, and GNARK has the smallest proof size."

Sui First Among L1 Chains to Run Scion Architecture, Countering Internet Routing Attacks

Sui, a blockchain built around the Move smart-contracts programming language, has become the first layer-1 project to drop the aging Border Gateway Protocol (BGP) and is now running Scion’s next-generation network architecture.

According to the team: "The upgrade provides validators with a complete defense against the internet routing attacks that have caused other networks to experience major downtime. Sui's resilience to network hijacking and DDoS attacks is greatly enhanced by the implementation of Scion, which enables failover between networks. Validators maintain consensus during attacks, improving epoch rewards. Full nodes benefit from better state sync, eliminating bottlenecks and retry delays." (SUI)
