3. Blockchain Industry Outlook
Public chains evolving
toward different directions
• Bitcoin, Ethereum, etc. which will
become the future of public chain?
No conclusion yet.
• Major challenge: long delay of
transaction confirmation, high cost
of power consumption
• Main drive of evolution comes from
communities
Consortium chains getting
closer to maturity
• Competition between open source
platforms and enterprise solutions
• A growing number of POCs by big
corporates in various use cases
• NOT YET THERE: still no production
application breakthrough
Ant Blockchain
• Financial-grade consortium chain
infrastructure
• Production-ready for commercial,
government, and financial use cases
• Proprietary platform development,
tackling technical and engineering
challenges
