Time, in Bitcoin, is simply work.​​​​​​​​​​​​​​​​ Every 10 minutes, miners compete to add a new block. This process, governed by proof-of-work, acts as a tick of the clock. The difficulty of mining adjusts automatically to maintain this rhythm, meaning the network self-corrects to stay on schedule regardless of how many miners participate. Each block references the one before it, creating a causally ordered sequence — you can always determine what happened before or after something else. This is called chronological consensus without any central authority. Unlike traditional timekeeping (which relies on trusted servers or atomic clocks), Bitcoin’s clock is: ∙ Trustless — no single party controls it ∙ Censorship-resistant — no one can rewind or skip ticks ∙ Global — the same for every participant on 🌎 Earth.
