    Governance Adaptation in Distributed Autonomous Organizations (DAOs)
    (2024-01-03) Riggins, Fred; Fosso Wamba, Samuel
    Distributed autonomous organizations (DAOs) are a new organization form that resides entirely on a blockchain. In a DAO, organizational governance rules are hardcoded in an immutable smart contract. This paper examines whether DAOs are able to adapt their governance structures when shocks in the external environment occur. If the DAO is truly decentralized and governance is hardcoded in a smart contract, then effective adaptation may be a challenge. Using case examples, we illustrate approaches to governance adaptation including orderly voting by DAO members, contentious voting with exit by some participants as the DAO evolve, hard forks in the event of negotiation failure, off-chain resolution mechanisms, and the role of a “benevolent dictator”. We provide justification for why DAOs may not be as decentralized as conceptualized if they are to be effective. Our research contributes to the theoretical development of DAO management strategies as this new organizational form evolves.

    Decentralized Oracle Network for Enhanced User Authentication: Transitioning from Centralized Oracle
    (2024-01-03) Gorawska, Anna; Swierzy, Piotr
    Blockchain has gained traction for its decentralized nature, transaction security, transparency, and immutability. However, integrating external information requires using oracle services, which introduce complexities and vulnerabilities that can compromise the reliability and integrity of blockchain-based applications. This paper addresses the challenge of oracle decentralization using our MetaMail system as an example. MetaMail enables user authentication and transaction confirmation in Ethereum via email (using OAuth 2.0 protocol). Initially relying on a centralized oracle, the MetaMail system faced vulnerabilities with the oracle as a single point of failure. The proposed Decentralized Oracle Network (DON) enhances user authentication, validation reliability, security, and trustworthiness, effectively mitigating risks connected to centralized oracles. We discuss the DON's architecture and security considerations. The comparative analysis highlights the advantages of a decentralized approach and emphasizes the potential of DONs for user authentication and data validation in blockchain-based applications.
