Chapter 7 is Wei Xu’s home turf. After theory-heavy chapters, Gong pivots to China: where blockchain left the whitepaper and touched invoices, courtrooms, and mango supply chains.
Why China moved fast
Gong opens with big numbers. Gartner projected $176B blockchain market value by 2025 and $3.1T by 2030. Take forecasts with salt, but the direction was clear: governments and enterprises were spending.
China’s angle: low-trust coordination at scale. Finance, logistics, and public records all need shared truth without one boss forging data.
Financial use cases
Supply chain finance. JD Finance’s 2017 asset cloud factory put loan verification on-chain. Three nodes (apply, approve, loan) plus payment channel coupling. Tencent’s 2018 receivables product did similar for SMEs.
Credit data. Gongxinbao and Bubi/Tiancheng built exchange layers for authorized user data. Idea: tamper-proof provenance, searchable listings, less fraud in credit markets.
Insurance. Blockchain for transparent policies and automated claims via smart contracts. China Construction Bank plus IBM pilot. Shanghai Insurance Blockchain Platform (2017) claimed 50,000 fingerprint verifications per second for policy deposits.
These are permissioned consortium chains, not public DeFi. Gong does not pretend they are Bitcoin. They solve reconciliation pain between institutions that already trust each other a little.
Government and courts
Electronic evidence. Zhejiang DataQin’s chain landed in Hangzhou Internet Court. First case where blockchain-stored evidence was accepted. Traceability beats “trust me” screenshots.
Inter-agency data sharing. Guizhou’s judicial big-data platform cut supplementary investigation rates and shortened case times by sharing police, prosecutor, and court records.
Arbitrage Chain (2018). WeBank, Guangzhou Arbitration Commission, and partners put arbitration evidence on-chain. Dispute? Pull hash-verified records instead of mailing paper.
Food safety
Scandals (toxic milk powder, gutter oil, “zombie meat”) pushed traceability demand.
Wal-Mart, JD, IBM, and Tsinghua formed the Safe Food Blockchain Traceability Alliance (2017). Wal-Mart’s mango trace demo dropped from days to 2 seconds. JD put 100+ brands on-chain.
Real benefit: faster recalls, less guessing during outbreaks.
Why China leads on deployment (per the book)
Gong lists policy tailwinds:
- 2016 Five-Year Plan listed blockchain next to AI and IoT
- 2018 Xi Jinping speech flagged blockchain as breakthrough tech
- 2019 patent data: Chinese firms filed ~3x US blockchain patents
- Alibaba, China Unicom, Ping An topped global patent charts
- CESI certification lab stress-tested 30 projects
- DCEP (digital yuan) research: two-tier model (PBOC to banks to public), M0 replacement, better monetary telemetry
My reaction
Chapter 7 reads like a 2018-2019 industry report baked into a textbook. Company names and pilot stats will age. The pattern holds: China’s blockchain story is enterprise and state led, not cypherpunk led.
That is not a knock. Gong is clear these are mostly permissioned systems. They still use consensus, crypto, and incentive design. They just optimize for compliance and throughput, not anonymous money.
Compare to Silicon Valley’s 2017 ICO carnival. China’s output looks boring on Twitter. Boring can mean invoices that reconcile and court evidence that holds up.
DCEP section is snapshot-era. The digital yuan launched in pilots since then. Read it as context for why Gong thought token economics would meet central bank policy, not as current CBDC doctrine.
If you want geopolitical blockchain analysis, this chapter is a useful primary source from inside the Chinese industry conversation.
