Many of us remember the early days of the internet in 1995—dial-up modems, slow-loading websites, and limited functionality. Today, the internet is poised for another transformation, driven by blockchain technology. As outlined in Blockchain Revolution (2016), blockchain shifts the focus from sharing information to securely transferring assets—money, intellectual property, and personal data—without intermediaries like banks or governments. This innovation has far-reaching implications across industries, from finance to healthcare.
Industries Transformed by Blockchain
1. Supply Chain Management
Blockchain ensures transparency in complex supply chains. For example:
- IBM and Walmart collaborated on a blockchain-powered food traceability system to quickly identify contamination sources.
- Seafood fraud affects ~30% of the U.S. market; blockchain can verify origins and reduce mislabeling.
2. Healthcare
Blockchain enables patient-controlled medical records:
- Toronto’s University Health Network lets patients store digital health identities.
- Patients could monetize or donate their data for research via blockchain.
3. Financial Services
Beyond cryptocurrencies, blockchain revolutionizes trade finance:
- Banks adopting blockchain platforms see faster, error-free transactions.
- Tokenization raised over $10 billion in 2018 for startups via equity or utility tokens.

Blockchain for Social Impact
Smart Contracts
- Enforce fair agreements (e.g., ensuring Uber drivers receive equitable pay).
- Musicians like Imogen Heap use blockchain to bypass exploitative industry practices via platforms like Creative Passport.
Energy Efficiency
- Power Ledger’s peer-to-peer energy trading promotes renewable usage and grid efficiency.
Democratic Voting
- Blockchain could enable secure digital voting, increasing participation and trust.
Challenges to Adoption
Despite its potential, barriers include:
- Resistance from industries threatened by decentralization.
- Early adopters (like those in INSEAD’s Blockchain Revolution for the Enterprise course) will gain a competitive edge.
