Each node is a Bitcoin transaction. Each edge is a flow of Bitcoin from one transaction's output into the next transaction's input. Transactions are labeled by the real-world entity behind them: licit (exchanges, wallet providers, miners, licit services) or illicit (scams, malware, ransomware, ponzis, terrorist organizations). 77% are unlabeled.
The dataset spans 49 consecutive ~2-week snapshots. Edges in Elliptic don't cross step boundaries and no node appears in more than one step — so the brush below picks one step at a time, and the graph you see is exactly that step.
Drag the brush, click a bar, or use ←/→ to move through time.
