10	Financial System Challenges & Opportunities	What are the tradeoffs of centralized institutions and markets in the financial sector? Which challenges of the financial sector—periodic crises, concentrated risks, economic rents, legacy systems, processing risks, financial inclusion—might present opportunities for blockchain applications? How does blockchain technology fit within other trends—particularly with regard to technology—facing the financial sector in 2018?
11	Blockchain Economics	How do decentralized blockchain applications affect the cost of verification and the cost of networking? How do blockchain applications affect market power? What might the economics and organization of the Internet—with its protocol layers and applications—tell us about the future of blockchain technology? What lessons should be drawn from crypto skeptics—Krugman, Stiglitz, Roubini, Gates,  Buffett, Dimon, & others about the economic potential for blockchain technology? What is an answer to the oft stated query:‘what problem do cryptocurrencies solve?’
12	Assessing Use Cases	What potential benefits—in terms of reducing costs of trust—are there when adopting blockchain technology applications? How might potential use cases be assessed for the trade-offs of decentralized vs. centralized applications? What are the potential strategic benefits from blockchain applications? What are the attributes of potential use cases and sectors that might best capture value from such applications? How important are the benefits of censorship resistance to this analysis? How can you separate rigorous analysis from mere assertion and hype in the blockchain ecosystem?
13	Payments, Part 1	What are the major trends—mobile apps, digital wallets, open banking, and enhanced methods of bank transfers & authentication—in payment systems today? What lessons can be drawn from non-blockchain payment innovations, such as Alipay, WeChat Pay, M-Pesa, India’s IMPS, and U.S. mobile payment apps? What are the challenges and opportunities in the current cross-border payment system architecture?
14	Payments, Part 2	What lessons can be drawn from the challenges for blockchain related payment applications? Might Layer 2 solutions, such as Lightening, resolve these challenges? What are the opportunities in cross-border payments? In domestic P2P or P2B payments? What are tradeoffs of utilizing permissioned vs. permissionless payment applications?
15	Central Banks & Commercial Banking, Part 1	What strategic considerations should go into Central Banks thinking of expanding access to digital reserves through central bank digital currency (CBDC)? How might design considerations—retail vs wholesale access; token or account based; interest bearing and level of service—weigh in such decisions? What are the challenges CBDCs might pose to commercial banking models, monetary policy implementation, payment systems resilience and financial stability?
16	Central Banks & Commercial Banking, Part 2	What lessons, if any, can be drawn from related experimentation— Ecuador, Senegal, Philippines— to date? Might stable value coins spur central banks into adopting CBDCs? What might Mastercard be considering with their patent for ‘blockchain currency’ fractional reserves? What recommendations would you have for Sweden’s Riksbank (dating from 1668, the world’s first central bank) for possible adoption of e-krona?
