Members of Bitcoin Alpha 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.

Members of Bitcoin Alpha 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.

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.

In this work we study the bitcoin-otc and bitcoin-alpha networks. These networks are modeled as directed weighted signed networks (WSNs) with users as nodes and time-stamped edges …

Network types Directed : directed network Undirected : undirected network Bipartite : bipartite network Multigraph : network has multiple edges between a pair of nodes Temporal : for each …

Due to the anonymity, there is a need to identify untrustworthy Bitcoin traders to avoid risky transactions. Bitcoin OTC2 and Bitcoin Alpha3 are two major Bitcoin rating datasets [7].

Our third source of data is the Bitcoin Alpha Trust Network, which is also available on SNAP. This dataset is similar in almost every way to the OTC bitcoin trust network.

We will perform our analysis on two main data sets: bitcoin-alpha and bitcoin-otc. Both bitcoin-alpha and bitcoin-otc are trust networks comprised of user ratings on various IRC channels.

In recent years, Bitcoin has established itself as the leading decentralized, cryp-tographic currency. In the process, the value of individual Bitcoin currency has skyrocketed in value, …

However, this hold out was maintained to ensure comparability with the results of node2vec, in which the validation set was used to pick the parameters p, q for each of Bitcoin OTC (p 0.25,q …
