Adaptive Sharding in Untrusted Environments

Summary: Marlin: adaptive sharding for untrusted environments, using runtime monitoring and dynamic reshuffling to preserve scalability and performance under adversarial nodes. Offers a centralized hypergraph-partitioning baseline and a decentralized, no-trust design that continuously reoptimizes shards for dynamic workloads and attacks.
