bitcoin_alpha — Bitcoin Alpha trust network (2017)
- Description
A who-trusts-whom network of users of Bitcoin Alpha, an online platform for trading with Bitcoin. Since Bitcoin users are anonymous, the platform let members rate each other to build a record of reputation that helps prevent transactions with fraudulent or risky users. A directed edge $i \to j$ means that user $i$ rated user $j$, on a scale from -10 (total distrust) to +10 (total trust) in steps of 1 (a rating of 0 is not possible). The data, covering ratings made from November 2010 to January 2016, were collected and released by S. Kumar and collaborators as the first explicit weighted signed directed network available for research.
The network has the following properties:
- Nodes:
name, the anonymized user identifier. - Edges:
rating, the rating (an integer from -10 to +10, excluding 0);time, the time of the rating, in seconds since the Unix epoch (with a resolution of one day).
