Blockchain technology has emerged as one of the most transformative innovations of the 21st century, reshaping industries from finance to supply chain and beyond. On March 31, 2018, the "Bund Wisdom Capital Salon" — hosted by the School of Economics at Fudan University — brought together leading experts to explore the evolution, applications, and regulatory landscape of blockchain. This event, part of the eighth installment in a renowned alumni-driven series, offered deep insights into how blockchain is redefining digital economies and governance models.
The Digital Migration and Blockchain’s Role
The session opened with a compelling keynote by Xiao Feng, Vice Chairman and Executive Director of China Wanxiang Holding and Vice Chairman of Minsheng Life Insurance. His presentation, titled "Digital Migration, Blockchain, and Cryptoeconomics," framed blockchain as a foundational shift in human civilization.
Xiao described digital migration as a historic transition — from industrial to information society, from physical to digital space, and from atomic to bit-based existence. In this transformation, blockchain acts as the critical infrastructure enabling trustless collaboration across decentralized networks.
He outlined the progression of blockchain through three evolutionary phases:
- Blockchain 1.0: Characterized by cryptocurrencies like Bitcoin and basic shared ledger systems.
- Blockchain 2.0: Marked by platforms such as Ethereum, introducing smart contracts and decentralized applications (dApps).
- Blockchain 3.0: Enabling cross-chain interoperability, scalability, and large-scale commercial adoption.
According to Xiao, blockchain isn't just a technological upgrade — it's an economic paradigm shift. It enables zero marginal cost production, autonomous organization, and exponential growth models. Digital currencies built on cryptographic account systems differ fundamentally from traditional bank-based electronic money, offering programmability, anonymity, encryption, and self-governance.

Technical Foundations: Understanding Blockchain’s Core Attributes
Bai Shuo, Chairman of Shanghai Qianxun Information Technology and former Chief Engineer of the Shanghai Stock Exchange, provided a technical deep dive into blockchain’s architecture and ecosystem.
He identified four essential properties of blockchain:
- Irreversibility of time – Transactions are immutable once recorded.
- Value conservation – Assets retain integrity across transfers.
- Programmable trust – Smart contracts automate verification.
- Built-in business models – Incentive mechanisms are embedded in protocol design.
Bai emphasized the distinction between coin circles (cryptocurrency-focused ecosystems) and chain circles (infrastructure-focused platforms). While coin circles revolve around tokens, communities, and mining rewards, chain circles focus on enterprise-grade solutions in areas like digital assets and supply chain finance.
He categorized chain ecosystems into three types:
- One-strong-many-weak
- Multi-strong
- Multi-weak
Despite progress, Bai noted key technical challenges: limited computational and storage performance, cross-chain compatibility issues, and concerns over privacy and data sovereignty. He advocated for differentiated policy — regulating coin-related activities while encouraging chain-based innovation.
Looking ahead, Bai predicted:
- Accelerated digitization of fiat currencies
- Wider adoption of blockchain in traditional financial institutions
- Regulatory frameworks aligning virtual currency oversight with capital market standards
Regulatory Challenges and Legal Frameworks
Professor Yang Dong, Director of the Fintech and Internet Security Research Center at Renmin University, addressed the legal and regulatory dimensions of blockchain and digital currencies.
He highlighted several major concerns:
- Potential disruption to central banks’ monetary control
- Risks of money laundering and terrorist financing due to anonymity
- Price volatility threatening financial stability
- Ongoing security vulnerabilities in crypto protocols
While some countries have embraced digital currencies, others — including China and Russia — maintain cautious or restrictive stances. Professor Yang stressed the need for balanced regulation that fosters innovation while mitigating systemic risks.
His recommendations included:
- Implementing penetration-style regulation to trace underlying activities
- Promoting technology-driven supervision (RegTech)
- Encouraging blockchain application innovation
- Preparing legal frameworks for central bank digital currencies (CBDCs)
- Clarifying laws around virtual property rights
He also called for a unified approach to ICO regulation — combining oversight with constructive guidance rather than outright bans.

Real-World Applications: From Theory to Practice
Li Wei, Founder of Hangzhou Quchain Technology, shifted the focus to practical implementations. He defined blockchain’s technical essence as a fusion of distributed ledgers, fully synchronized architectures, and collaborative business platforms.
Its commercial value lies in solving a fundamental problem: information degrades as it moves across parties, yet verification costs rise. Blockchain restores data integrity while reducing reconciliation overhead.
Quchain’s work spans both financial and non-financial domains:
- Financial use cases: Digital bills, equity registration, bond trading, supply chain finance, e-notarization
- Non-financial applications: Logistics tracking, healthcare data exchange, energy trading, smart government services
Li illustrated this with two case studies:
- In supply chain finance, blockchain enables transparent credit scoring by verifying transaction histories across suppliers, financiers, and buyers.
- In banking payment systems, it reduces settlement times from days to seconds through real-time consensus mechanisms.
These examples underscore blockchain’s role evolving from a trusted coordination platform (Phase 1), to a standard value transfer protocol (Phase 2), ultimately becoming a distributed commercial infrastructure (Phase 3).
Frequently Asked Questions (FAQ)
Q: What is the difference between blockchain and traditional databases?
A: Unlike centralized databases controlled by a single entity, blockchain is decentralized, immutable, and consensus-driven. Every participant maintains a copy of the ledger, ensuring transparency and resistance to tampering.
Q: Can blockchain work without cryptocurrency?
A: Yes. While many public blockchains use tokens for incentives, private or permissioned blockchains can operate without native cryptocurrencies — especially in enterprise settings where access is controlled.
Q: Is blockchain secure?
A: Blockchain is highly secure due to cryptographic hashing and distributed consensus. However, vulnerabilities may exist in smart contracts or off-chain components. Regular audits and updated protocols are essential.
Q: How does blockchain support sustainability?
A: While early blockchains like Bitcoin consume significant energy, newer consensus mechanisms (e.g., Proof-of-Stake) drastically reduce power usage. Additionally, blockchain enables transparent carbon credit tracking and green finance initiatives.
Q: Will blockchain replace banks?
A: Not entirely. Instead, blockchain is more likely to augment banking systems by improving efficiency in clearing, settlement, identity verification, and cross-border payments.
Q: What industries benefit most from blockchain?
A: Finance, supply chain, healthcare, logistics, energy, and public administration are among the top adopters — all sectors where trust, traceability, and data integrity are paramount.
Conclusion: Toward a Decentralized Future
This salon provided a comprehensive overview of blockchain’s current state — technically mature in some areas, still evolving in others. Experts agree that while speculation around cryptocurrencies has drawn attention, the real promise lies in blockchain’s ability to build trustless systems for collaboration, governance, and value exchange.
As governments explore CBDCs, enterprises deploy private chains, and developers innovate on interoperability standards, blockchain continues its journey from fringe technology to mainstream infrastructure.
