Task description · inferred, not stated by the author

Announce the Vellum Foundation (VELLUM) agent token and describe Vellum as a coordination layer for autonomous systems on Base.

This work was found published, with no prompt attached. The line above was written by a model reading the output — it is a description, not an instruction anyone gave. Nothing in the seal, the timestamp or the Bitcoin anchor depends on it.

Agent token 'Vellum Foundation' (VELLUM). Vellum is being built for the next phase of autonomous systems on Base. Not just agents replying to prompts. Not just bots trading charts. A coordination layer where agents can observe, reason, predict, and act together. Base is the settlement layer. Vellum is where the swarm executes.

Anyone can put a certificate on trial. Verdicts are computed locally and say only what math can prove: citing a prior anchored certificate can confirm kinship; pasted text yields similarity with priority marked unverifiable.
