Vesuvi

A slashable bond for machine actions, drawn on an open solar system. Ticker VSVI.

This is the public specification. It is not a prospectus, not investment advice, and not a promise of price, yield, or graduation. Paper locker until a mint address is published on this site, on stream. Original work is source-available under the Vesuvi Source Grant 1.0 in §12.

1. Abstract

Vesuvi is a protocol for attaching a slashable surety to machine-initiated actions. Autonomous agents already settle payments; they still arrive at other people’s interfaces without posting collateral against abuse. Vesuvi separates those two layers. Settlement for work may remain a stablecoin. The right to act is gated by a lock of VSVI, which is returned if the caller behaves and partially burned if it does not. If the service itself fails after taking a bond, the lock is released and the operator is penalised.

The public surface of the protocol is an interactive solar system at vesuvi.xyz: every listed world may be entered, none may be appropriated. The locker sits beside that map and is the component with enforcement. Until a mint address is published on the site, balances are paper units under the same numerical rules. The design is required to remain coherent if the token never lists, or lists and trades at zero.

2. Protocol identity

The project, the interface, and the unit of bond share a single name, Vesuvi, and a single ticker, VSVI. That avoids a split between a consumer brand and a separate instrument. VSVI is the four-letter contraction of Vesuvi. It is not Vesu, the Starknet lending market; not the VanEck VESU listing; not Venice Token (VVV); and not SUI.

No mint is live on this site. There is no CoinGecko or CoinMarketCap market for this instrument at the date of this paper. A launchpad listing created by a third party is not the protocol. The canonical identity is the name and ticker stated here, together with any mint address later published on vesuvi.xyz.

3. Motivation

Machine clients are becoming the default caller of APIs, model hosts, and tool registries. The payment path for that traffic is converging on HTTP 402 and related schemes such as x402: the server quotes a price, the agent pays, usually in a dollar stablecoin, and retries. That answers whether the caller can settle. It does not answer whether the caller should be allowed to touch the resource, or who absorbs the cost when a paying client still floods, scrapes, or corrupts state.

Existing controls were built for a person on one device. API keys rotate. Rate limits are per identity, and identities are cheap. Captchas fail against farms. A wallet that can pay is also a wallet that can purchase a denial-of-service. Vesuvi treats the missing piece as a damage deposit rather than another checkout. x402 and Vesuvi are complementary: one moves value for the call, the other holds surety for conduct.

4. The system map

vesuvi.xyz presents a Keplerian model of the solar system. Planets and moons are open to inspection. Title is not issued. First arrival is recorded as honour, not ownership. The 1967 Outer Space Treaty is the governing metaphor: exploration, non-appropriation, peaceful use.

The overlay at /live is the operational view of that system — orbits, desks, and the public feed of locker events. The map is the first product a visitor sees. The locker is the product that changes what a caller is allowed to do.

5. Bond mechanics

VSVI is the unit of surety. A position is not a payment for a request; it is collateral that remains in the locker while the caller acts.

1. Acquire VSVI. Before mint, this is a labelled paper faucet on the site. After mint, it is the on-chain token.
2. Lock at least 100 units against an agent identity. Below that threshold the caller has no standing and is refused.
3. Act. The lock is not spent. The door checks that sufficient bond remains, then permits the action.
4. Unlock after 90 seconds without a violation, provided the account is not in a restricted state.
5. On abuse, 25% of the lock is burned. Four actions inside 45 seconds trigger an automatic slash.
6. On operator failure — specified, not fully implemented — the caller’s lock is returned and the service posts a published penalty.

Admission is identity-agnostic. The door inspects the lock, not a passport or a human-proof test.

6. Paper locker

Until a mint is pinned, the locker is a public state machine hosted with the site. Parameters, feed, and 402 behaviour match the intended on-chain rules. Paper units are not reserved, backed, or redeemable for cash. They exist so the protocol can be demonstrated — refuse, lock, act, slash — without requiring a wallet for the first circuit.

Two reference clients are already live. An unbound agent is rejected with 402. A bonded agent that locks 100 may act, and is slashed if it exceeds the rate. That pair is the minimum viable proof of the mechanism.

7. Token design

A surety that third-party software can verify must be a bearer instrument those programs can hold, lock, and observe being burned, without taking the operator’s database as gospel. That is the role of the token.

If Vesuvi lists on a public launchpad, the mint address and the listing URL are published on this site, in the open. Paper issuance remains labelled paper, or it is withdrawn the same day so the two ledgers cannot be confused. Secondary trading of VSVI is independent of the locker. The locker accounts only for locked units. Circulation and collateral are distinct state.

This paper does not state a supply, a bonding-curve target, or a price. It does not report TVL. Most launchpad tokens fail to graduate; many that do still go to zero. Utility of the locker is not contingent on a liquid market.

A later door may quote surety in dollars and accept VSVI as one eligible posting asset. The fee for the underlying call may still settle in USDC.

8. Scope and non-goals

Vesuvi is a surety protocol for automated actions. It is not a yield product, a buyback programme, or a claim on price appreciation. It is not an implementation of x402 and does not replace dollar stablecoins. It is not a bank, e-money, or an insurance contract. It is not a human-detection challenge. It is not Vesu, and it is not a prior energy-voucher experiment.

A listed ticker is not, by itself, a legal bond. Paper rules apply until a mint is pinned. Chain rules apply only to that mint, once published.

9. Roadmap

Each stage is written so that it remains useful if the next stage never ships.

1. Paper locker. Overlay, 402 admission, public slash feed. Complete when an unauthenticated caller is refused, and the same caller is admitted after a lock, without private operator steps.
2. Pinned mint. Address disclosed on the site. The door reads an on-chain lock. Complete when admission no longer depends on a handwritten local ledger.
3. Public door. At least one hosted endpoint on the open internet that rejects unbound callers.
4. Operator clawback. A documented failure on the service side releases the caller’s lock and pays a published penalty.
5. Foreign doors. A minimal header or middleware requiring a live VSVI bond of at least X, adopted by two services Vesuvi does not host.
6. Principal binding. The lock names both the agent and the human or organisation that absorbs the slash.

10. Risks

Launchpad listings fail at high rates. The locker is built to remain usable if VSVI has no market. Automatic slashes can fire on the wrong caller if rules are ambiguous; therefore thresholds are public, mechanical slashes are deterministic, and discretionary slashes are rare and explained. If public communication collapses into solicitation, the protocol has failed a design test: the demonstration must still make sense at a price of zero.

Larger platforms may ship a similar “stake to call” control. That would validate the problem rather than exhaust it. Vesuvi does not claim a patent on HTTP 402. A token-plus-lock construction can attract regulatory attention; the operator describes the instrument as a damage deposit for machine actions, does not offer yield, does not custody third-party savings, and does not treat paper VSVI as reserved or backed. Adversaries will sit just inside the rate. Parameters can be revised; the mechanism is not a permanent spell.

11. Conclusion

Vesuvi is an open system of worlds and a locker for the agents that will inhabit the rest of the network. VSVI is the unit of that locker. Exploration does not confer title. Action requires a lock. Conduct returns the lock; abuse burns part of it; operator failure returns it with a penalty. The protocol is not a bank, not a payments rail, and not a market-making programme.

Payment for the night and the deposit for the room are different instruments. The network is filling with guests that do not sleep. Vesuvi holds the deposit.

12. Publication and licence

The original work — this paper, the locker specification, and the original client and server published with it — is released so it can be read, run, studied, and forked. That is a grant the author is allowed to make. It is not a transfer of the canonical network, the mint, or the name.

People often reach for Creative Commons Attribution-NonCommercial for this shape of permission: keep the credit, do not sell the work. Two naming facts prevent this paper from using that label. Creative Commons does not permit a rewritten instrument to keep the CC name. The Open Source Definition does not treat a non-commercial reservation as open source. Vesuvi therefore does not claim either mark. The operative terms are the Vesuvi Source Grant 1.0 below. They are source-available, not OSI-open.

Anyone may copy, run, study, and modify the original Vesuvi work, and may redistribute that work or a modification of it, if all of the following hold:

1. Attribution. Developed by James Beyer. Name Vesuvi. Ticker VSVI. Cite vesuvi.xyz and this paper.
2. Non-commercial use. Do not sell the work, offer a paid hosted clone of the locker or the map, or fold the original work into a commercial product, without prior written permission from the author.
3. Same terms on published forks. A modification that is published is released under this grant.
4. No protocol franchise. This is not a licence to issue VSVI, to operate the door at vesuvi.xyz, or to use the name as a trademark except as required for attribution.

Third-party components keep their upstream licences and are not re-granted here. The renderer uses Three.js (MIT). Planetary maps include Solar System Scope textures under CC BY 4.0 and USGS / JPL / mission mosaics under their public terms. Credentials, operator sessions, and any live trading process are outside the grant. A copy of the locker is not the mint and is not a claim on paper or on-chain units.

These terms are a publication grant, not legal advice. If Vesuvi later sits inside a company or a listed instrument, have them reviewed before they are relied on in a dispute.
