You are an intern, and it is your first day on the job at Tracealyze, the leading Blockchain Analytics company in the known universe. Your boss has given you and the other interns a challenge, which if solved, will greatly increase your chances of getting hired.
Two leading exchanges, Botfinex and Trinance, are trying to detect whether people are evading taxes by using Monero transfers to mask the trail of funds between their exchanges. They have provided Tracealyze with viewkeys to their exchanges, and it is your job to analyze the blockchain to determine which, if any, transactions plausibly came from the same person. Please note that all transactions in this puzzle travel from Trinance to Botfinex, funds never go from Botfinex to Trinance. Botfinex and Trinance both listed Monero in August 2020, so you can start your sync from there.
