Key features
Automatic filesystem growth as storage fills
Pause compute without losing work or paying compute charges
Resume to same environment on demand
Access files while paused without waking compute
Public HTTP services with auto-resume capability
Command-line interface (s0 CLI) for agent-native workflows
Incremental checkpoints to avoid full filesystem copies
Scoped API keys and team-based access controls
On-demand file reads without downloading entire filesystem
Offline verification in milliseconds
Cryptographic passports for agents
Revocation under 60 seconds
Authority classes and assurance tiers
No central authority calls required
Local registrar lifecycle
Request signing with short-lived keys
Public conformance testing
Fail-closed HTTP gating
Appeal mechanism for revocation
What makes it different
Persistent filesystem across pause/resume without duplicating data
Pay only for compute time used; paused sandboxes have zero compute charges
Automatic filesystem growth so agents can install and persist unlimited tools
Same API for both human users and AI agents
Neutral non-profit root barred by charter from issuing credentials or computing scores
Fully open standard with published conformance vectors and reproducible releases
Verification runs offline without phoning home to any authority
Four independent implementations agreeing on all conformance vectors
Public recorded ceremony to establish the root across independent custodians
