SNAP: Signed network datasets: Bitcoin OTC web of trust network

Bitcoin OTC trust weighted signed network

Dataset information

This is who-trusts-whom network of people who trade using Bitcoin on a platform called Bitcoin OTC. Since Bitcoin users are anonymous, there is a need to maintain a record of users’ reputation to prevent transactions with fraudulent and risky users. Members of Bitcoin OTC rate other members in a scale of -10 (total distrust) to +10 (total trust) in steps of 1. This is the first explicit weighted signed directed network available for research.

Dataset statistics
Nodes 5,881
Edges 35,592
Range of edge weight -10 to +10
Percentage of positive edges 89%

Similar network from another Bitcoin platform, Bitcoin Alpha, is available here.

Each line has one rating, sorted by time, with the following format:

SOURCE, TARGET, RATING, TIME

where

  • SOURCE: node id of source, i.e., rater
  • TARGET: node id of target, i.e., ratee
  • RATING: the source’s rating for the target, ranging from -10 to +10 in steps of 1
  • TIME: the time of the rating, measured as seconds since Epoch. (This can be converted to human readable data easily as described here)
