T-EDGE: Temporal WEighted MultiDiGraph Embedding for Ethereum Transaction Network Analysis

1 code implementation13 May 2019 Jiajing Wu, Dan Lin, Zibin Zheng, Qi Yuan

By taking the realistic rules and features of transaction networks into consideration, we first model the Ethereum transaction network as a Temporal Weighted Multidigraph (TWMDG), where each node is a unique Ethereum account and each edge represents a transaction weighted by amount and assigned with timestamp.
