Recently, I've been observing those "coincidental transfers" on the blockchain—sometimes A sends to B, then B sends to C, and the timing is just right... Many people’s first reaction is insider trading or money laundering. Frankly, don’t rush to jump to conclusions; I usually break down the path first: Is this money coming from the same source (exchange hot wallet, a protocol’s treasury), is it passing through batch consolidations/fee reimbursements/bridges, and does the final destination return to the same set of addresses in rotation? Connecting these nodes, many "coincidences" turn into traceable process footprints. Modularization and the DA layer have recently been hot topics among developers, but for ordinary users, it’s really confusing: longer chains, more points where issues can occur, permissions and custody points hidden deeper... Now, I pay more attention to "who can move this money and when it can stop" when looking at transfers—less guessing the story, first find the switch.
