GHOST

The ephemeral execution layer for autonomous AI agents. Scoped, short-lived credentials with Ed25519-signed, tamper-evident residue — give your agent a body that vanishes the moment its task is done.

01What GHOST is

GHOST is the execution-safety layer beneath the x402 agentic web. Where NEXUS-402, 402PROOF and the XAH Portal handle discovery and payment, GHOST handles the dangerous part: actually running the task. It hands an agent a short-lived, scoped credential, supervises the execution, signs a tamper-evident record of everything that happened, and then evaporates — leaving cryptographic residue instead of a standing attack surface.

02Why it matters

No standing secrets. Credentials are minted per task, scoped to exactly what the agent needs, and expire on completion. Nothing lingers in a .env file to leak.
Cryptographic residue. Every action is Ed25519-signed and tamper-evident. You get proof of what ran without trusting the runtime.
Ephemeral by default. The execution body self-destructs — memory, state, and logic wiped after the receipt is fired.
Stack-native. Drops directly beneath NEXUS-402, 402PROOF, SqueezeOS and the XAH Portal.

03Lifecycle

$ ghost spawn # mint scoped, short-lived credential
$ ghost possess # attach agent to the ephemeral body
$ ghost act # execute task under supervision
$ ghost evaporate # wipe state, fire signed receipt
$ ghost replay # verify residue offline, anytime
→ execution proven · zero standing surface

04Install

$ pip install ghost-layer
# CLI: ghost spawn | possess | act | evaporate | replay

05The rest of the stack

Give your agent a body that vanishes.

GHOST is open-source and free. Ephemeral credentials, cryptographic proof, zero standing attack surface.
