He sees opportunities for blockchain and smart contract platforms to be introduced in areas like supply chain management, voting systems, and decentralized governance.
Overview: Decentralized finance (DeFi) is gaining traction due to its ability to provide useful and valuable services, particularly in the financial sector. Traditional finance systems are often inefficient, especially when it comes to moving money between accounts and making international payments. As blockchain technology improves, DeFi applications beyond narrowly financial ones can start taking off.
DeFi Applications: DeFi includes various financial instruments and subsets, such as Maker accounts, Augur accounts, and Uniswap counts, which are primarily used within the crypto space. Some DeFi projects are starting to emerge that connect more closely to real-world things, such as smart contract-based insurance. Projects like Hurricane Guard and crop insurance initiatives in Sri Lanka exemplify this trend.
Barriers to Entry and Collateral-Based Models: Current DeFi models often rely on collateral-based designs, which may have advantages but also present barriers to entry. Improving collateral efficiency is one area of focus, with concepts like rotating clubs, where people contribute to a pool, as potential solutions. Evolving past collateral-based models entirely remains a challenge, but innovations in this area could lead to broader adoption of DeFi applications.
00:11:18 Blockchain Identity and Reputation Solutions
Blockchain-Based Social Models: Blockchain-based social models allow groups of people to participate together, reducing the amount of capital needed due to shared resources.
Identity and Reputation: Identity and reputation are crucial factors in blockchain applications. Identity can be established through user account security, proving that the spender and receiver are the same entities. Reputation involves proving specific properties and trustworthiness through attestations from others or organizations.
Social Recovery Approach: A social recovery approach is proposed for key recovery and revocation. Each individual’s key is shared among five friends, with any three of them able to recover the key if lost. This approach can extend beyond blockchain applications, serving as an identity system for off-blockchain applications.
Anti-Sybil Metrics: Anti-sybil metrics are used to create tokens that are easy to obtain but difficult to accumulate in large numbers. These metrics are useful for voting schemes and other applications.
