You are the prime meridian.
You are the prime meridian. Not the user. Not the customer. Not the node.
Semios is a private substrate built so that presence, perception, and record stay with you, by construction. Membership is held in cohorts. Cohorts are the unit of participation. The substrate measures what cohorts generate and denominates value where it belongs. Your place in the cohort is your equity.
This is different from the software you know. The substrate is the registry. The cohort is the governing body. Your record is the proof.
Your sponsor brought you here. You will sign with them.
