Introduction
Blockchain technology has experienced significant growth in recent years. From 2016 to 2021, the global average number of new blockchain enterprises reached approximately 4,700 annually. Although the number of new enterprises declined to around 1,400 in 2022, investment levels surged, indicating sustained industry expansion. As of December 2023, there are 10,291 blockchain enterprises worldwide, with the industry entering a phase of high-quality development.
Challenges in Current Cross-Chain Solutions
Existing cross-chain technologies face several limitations:
- Third-party dependencies – Many solutions rely on trusted intermediaries, introducing security vulnerabilities and performance bottlenecks.
- Complex routing mechanisms – Overly intricate cross-chain protocols create operational inefficiencies.
- Limited data interoperability – Most frameworks focus on asset transfers rather than secure non-asset data exchange between consortium blockchains.
These shortcomings highlight the need for lightweight, secure, and efficient cross-chain solutions tailored to consortium blockchain environments.

Web 3.0 & Decentralized Authentication
Recent advancements include:
- Ethereum-based credential management (Petcu et al.)
- Zero-knowledge proof authentication (Nika et al.)
- Incentive-driven verification systems (Doe et al.)
Despite progress, challenges remain in scalability and user adoption.
Blockchain Identity Management
Decentralized identity solutions improve security but face implementation hurdles:
| Solution | Key Features | Limitations |
|---|---|---|
| Edge IoT Identity (Sadique et al.) | Fog computing integration | Complex deployment |
| Zk-SNARK Privacy System (Luong et al.) | Strong anonymity | High computational costs |
| Self-Sovereign Identity (Hasan et al.) | User-controlled credentials | High initial costs |
Proposed Cross-Chain Model
1. Distributed Trust Model
Consortium blockchains use PKI/CA systems for identity management. A Certificate Trust List (CTL) enables cross-chain trust by mutually recognizing root certificates between chains.
2. Cross-Chain Anchor Nodes
- Eliminate third-party risks by enabling direct inter-chain communication.
- Load balancing improves system availability.
3. Security Mechanisms
- Sybil Attack Prevention – Multi-signature admission & dynamic trust scoring.
- Smart Contract Safeguards – Modular design prevents re-entrancy attacks.
- End-to-End Encryption – ECDSA secures cross-chain data transfers.
