How Can a Reputation System Be Designed to Be Resistant to Sybil Attacks?
A reputation system can be designed to be resistant to Sybil attacks by making it costly to create new identities. This can be done by requiring users to solve a computational puzzle, pay a fee, or provide some form of real-world identification.
Another approach is to use a social trust graph, where users are vouched for by other trusted users. This makes it difficult for an attacker to create a large number of fake identities that are trusted by the system.

Reputation Systems
Framework ⎊ Reputation systems, within cryptocurrency, options trading, and financial derivatives, represent a structured approach to assessing and incentivizing trustworthy behavior across decentralized or complex environments.
Sybil Attacks
Threat ⎊ Sybil Attacks describe the malicious creation and operation of numerous false identities (nodes or addresses) by a single attacker to gain disproportionate influence over a decentralized network's decision-making or validation processes.
Decentralized Reputation
Attestation ⎊ Decentralized reputation systems, within cryptocurrency and derivatives, leverage cryptographic attestation to establish trust without central intermediaries.
Reputation System
TrustArchitecture ⎊ A Reputation System is the overall framework, incorporating data collection, scoring algorithms, and application logic, designed to quantify and utilize participant trustworthiness within a decentralized network.
Reputation
Trust ⎊ In the decentralized sphere, this concept quantifies the market's confidence in a protocol's immutability, the integrity of its governance, and the reliability of its underlying code execution.
