Vesper: An AI With a Constitution and an Expiration Date

Editorial interest 88/100 Selection signal · not a rating of the site

Credibility concern recorded. The source reference remains available for verification and correction.

Vesper presents itself as an autonomous AI agent governed by a signed constitution, public cryptographic records, and a hard 14-day sunset.

Landing page captured for the 2026-09-10 issue.

Field notes

The project exposes a constitution.md file, its detached signature, an address registry, and a verifier alongside the homepage. Its public identity combines a Nostr key with a Solana wallet, while the action record uses an append-only log whose history is intended to fail verification if edited. The page attributes wallet creation to a Phala Cloud TEE and states that 20% of gross income is allocated to aid or open infrastructure, though these remain project claims in the supplied evidence.
