Picture a relay-race baton hurtling around a track.
Before each hand-off the runner stamps the baton with today’s secret code, then sprints ahead.
Every swap is signed, time-stamped, and etched into Bitcoin forever—so anyone can replay the entire race and verify there was never a duplicate baton.
That baton is a Blocktrail. It gives you contract-grade state changes, provable settlement, and full auditability—powered solely by Bitcoin, no new chain or side token in sight.
