According to Foresight News, blockchain analysis company Chainalysis stated that the 300 bitcoins received by the founder of Silk Road may have originated from early suppliers of the dark web market AlphaBay. Chainalysis claims there are reasonable grounds to suspect that these funds came from AlphaBay.
Foresight News noted that AlphaBay was a dark web market for illegal goods and services founded by Alexandre Cazes, which was shut down in 2017.
