Abstract
En 中文
Light client verification is foundational for resource-constrained devices to achieve decentralized trust in consortium blockchains. However, traditional schemes such as Simplified Payment Verification (SPV) incur linear storage growth O(L) with block height. Although Merkle Mountain Range (MMR) accumulators offer theoretically logarithmic efficiency, current implementations face a critical deployment barrier: they rely on hard forks to embed accumulator roots into block headers. For deployed consortium blockchains, this necessitates invasive protocol upgrades that disrupt service continuity, rendering such solutions operationally prohibitive.
