This document summarizes Ant Blockchain technology and use cases. It describes how blockchain can enable shared records, communication and processing logic between institutions. It then outlines key features of the Ant Blockchain platform including high performance, global deployment capabilities, and enhanced security. Several example use cases are described, such as a charity platform, mutual aid program, and supplier provenance tracking.

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
