HFIPay: Privacy-Preserving, Cross-Chain Cryptocurrency Payments to Human-Friendly Identifiers
Jian Sheng Wang
Human-friendly identifiers such as email addresses and phone numbers are convenient payment targets, but direct mappings from identifiers to blockchain addresses make balances and…
ZK-ACE: Identity-Centric Zero-Knowledge Authorization for Post-Quantum Blockchain Systems
Jian Sheng Wang
Post-quantum signature schemes impose kilobyte-scale on-chain artifacts. Verifying them inside ZK circuits merely relocates the cost via expensive lattice arithmetic in prover circ…
MEV-ACE: Identity-Authenticated Fair Ordering for Proposer-Controlled MEV Mitigation
Jian Sheng Wang
Maximal Extractable Value, or MEV, remains a structural threat to blockchain fairness because a block producer can often observe pending transactions and unilaterally decide their…
n-VM: A Multi-VM Layer-1 Architecture with Shared Identity and Token State
Jian Sheng Wang
Multi-chain ecosystems suffer from fragmented identity, siloed liquidity, and bridge-dependent token transfers. We present n-VM, a Layer-1 architecture that hosts n heterogeneous v…
ACE Runtime - A ZKP-Native Blockchain Runtime with Sub-Second Cryptographic Finality
Jian Sheng Wang
Existing high performance blockchains verify one signature per transaction on the critical path, which creates O(N) verification cost, high hardware pressure, and difficult post qu…
ACE-GF-based Attestation Relay for PQC - Lightweight Mempool Propagation Without On-Path Proofs
Jian Sheng Wang
In post-quantum blockchain settings, objects that require validity proofs (e.g., blob roots, execution-layer or consensus-layer signature aggregates) must be broadcast through memp…
