Erasure‐Coded Sharding and Proof‐of‐Storage for Practical Blockchain Trilemma Balance
IET Blockchain, Volume 6, Issue 1, January/December 2026.The proposed storage‐first blockchain framework resolves the blockchain trilemma by synergistically combining decentralised storage, zero‐knowledge proofs and sharded proof‐of‐storage consensus. Empirical evaluation demonstrates a peak throughput of 2800 transactions per second with low latency and strong Byzantine fault tolerance, while substantially ...
