GriDB: Scaling Blockchain Database via Sharding and Off-Chain Cross-Shard Mechanism

Summary: GriDB restores sharded blockchain DB scalability by moving heavy cross‑shard exchanges off‑chain: a few randomly chosen delegates jointly produce succinct proofs that on‑chain consensus merely verifies, tolerating Byzantine faults. New authenticated data structures provide completeness/correctness/freshness/availability for verifiable relational cross‑shard queries and an off‑chain live load‑balancer enables scalable queries and updates.
