{ "title": "Engineering Sybil Resistance in Decentralized Systems", "content": | # Sybil Resistance in Decentralized Systems: A Technical Perspective Decentralized systems, such as those found in DeFi, are vulnerable to Sybil attacks. These attacks occur when an attacker creates multiple fake identities to manipulate the system. In this article, we'll explore the engineering approach to achieving Sybil resistance in decentralized systems. ## The Problem: Sybil Attacks in DeFi Sybil attacks are a significant concern in decentralized systems, as they can be used to manipulate voting outcomes, control resources, or disrupt the normal functioning of the system. The lack of a centralized authority makes it challenging to verify the authenticity of user identities. ## Standard Tools and Approaches Traditional solutions, such as CAPTCHAs or IP blocking, are often ineffective in decentralized systems. These approaches rely on a centralized authority to enforce the rules and can be easily bypassed by sophisticated attackers. ## Trestle's Solution: A Decentralized Identity Verification Approach Trestle offers a decentralized identity verification approach that uses a combination of cryptographic techniques and game theory to achieve Sybil resistance. By leveraging a reputation system and incentiv
