Decentralized trust systems, supported by blockchain technology, have the potential to reshape the way we manage trust and cooperation. This thesis delves into three fundamental aspects of blockchain-based decentralized governance systems, drawing parallels with the traditional legislative, executive, and judicial branches of governance. We explore the key challenges in each area. First, we introduce a judicial framework for blockchain systems by investigating the forensic support capabilities of a wide range of consensus protocols. This adds a crucial post-breach layer to traditional consensus mechanisms, enabling the identification and accountability of malicious actors following a security breach. Second, to strengthen the legislative branch in a cross-chain world, we present the TrustBoost protocol, which enhances trust across interoperable blockchains without requiring weaker chains to sacrifice their sovereignty, addressing the security imbalances that arise in cross-chain applications. Lastly, the dissertation proposes an incentivized watchtower network, secured by the Proof of Diligence protocol, for Layer 2 optimistic rollups. We develop a cryptoeconomic model that ensures diligent monitoring of transactions through properly aligned incentives, filling the gap in the executive role.
