1/ Everyone knows that time is money. In the digital realm, however, money is also intricately related to time. It has to be.


2/ Among other things, money solves a coordination problem. Trading a single good against others solves the combinatorial explosion of a barter economy. It is a scalability solution that allows coordination across large groups of people.

3/ The two basic forms of money are ledgers (made of information) and physical tokens (made of atoms). Physical tokens keep track of themselves. Ledgers need someone who is in charge.

4/ In the informational realm, only ledgers exist. And to make sure that transactions on a ledger are in order, a concept of time is required. In other words: Tokens are timeless, ledgers are not.

5/ A decentralized system can't rely on our human concept of time. A trustless, non-local time is required. Trustless, because we must not introduce a third party. Non-local because we don't have the luxury of a central frame of reference.


@dergigi very insightful. A trust minimized globally accessible clock is incredibly valuable. It allows us to measure value.
