Previous research has shown that sybils tend to send transactions only within their own community, and only when they intend to attack non-sybil communities. This behaviour creates clear \"bridges\" connecting sybils and non-sybils which can be used as a heuristic to detect attacks.\n\nOur team has been working closely with Gitcoin to develop new techniques which combine graph analysis and machine learning for the automatic detection of patterns such as these bridges. Our grant in the prior round extracted new graph based motifs for sybil detection, providing high precision classification even without the addition of standard features like wallet age. You can read our report on this work here: https://docs.google.com/document/d/1gTvIoHd9tb-68BWFHJgJIbFnAVXMsMtw_UvUEgX2icA/ \n\nBuilding on this, we propose two parallel courses of action. Firstly, we intend to continue this research thread, implementing new detection methods. Secondly, these techniques should be packaged in an intuitive workflow that allows DAOs to easily implement them and understand the output.  \n\n The workflow will include the following steps. Given a new/suspicious wallet we will:\n1. Automatically obtain transaction data of the suspicious user.\n2. Run our previous sybil detection techniques to obtain their graph features and motifs.\n3. Identify bridges and connections between the suspicious user and other communities.\n4. Output a sybil detection score and report of the findings.\n\nThis workflow can also be repeated periodically for the whole community to further improve the model and remove bad actors that pass initial checks. The workflow will be available as a script which can be executed within the DAO’s infrastructure as well as within the Pometry UI currently under development.\t\n\nThe project will be led by a full-time research engineer (Dr. Haaroon Yousaf) for 6 months, supported by the wider Raphtory and Pometry team consisting of leading researchers in graph theory, machine learning and on-chain analytics. Dr. Yousaf is already employed by Pometry, having worked on the initial grant described above. His prior work can be seen here https://www.haaroonyousaf.com.  \n\nThe total cost of this project will be £30,000, covering the salary of the researcher for the proposed period. \n\nNominations; DisruptionJoe and ale.k", "projectTwitter": ""}
