The document discusses three potential visions for the future of banking:
1) Ubiquity - Banks actively embed their services across markets and industries to play a more pervasive role. They focus on modularity and agility to seamlessly integrate financial services into value chains. 
2) Centrality - An open banking platform changes the relationship between fintechs and banks, with fintechs becoming paying customers. Banks focus on high-value opportunities and maximizing core competencies through automation and analytics. 
3) Nodality - Customers perform many traditional bank functions that have been automated or disintermediated. Banks provide infrastructure and act as trusted nodes connecting individuals and micro-banks powered by blockchain.
