How VerBnb works
VerBnb settles marketplace disputes with AI validator consensus - no call centers, no courts, fully on-chain. Here's everything you need to use it.
The basics
What is VerBnb?
Step by step
How to submit a dispute
- 1
Choose a category
Pick the dispute type that fits - rental, marketplace, sourcing, or delivery. Each routes to a specialist AI judge.
- 2
Describe your claim
Add the listing or order URL and explain what went wrong in plain English. No legal jargon needed.
- 3
Upload evidence
Drag in photos or documents. They're pinned to IPFS so validators can fetch them independently.
- 4
Submit on-chain
Your dispute is sent to GenLayer. You'll get a transaction link to follow along on the explorer.
- 5
Watch consensus
Track the live tracker as it moves through Submitted → Proposing → Committing → Revealing → Finalized.
- 6
Read your verdict
A refund percentage and the validators' reasoning are written on-chain permanently. Appeal within 7 days if needed.
No jargon
What is AI consensus?
When you submit a dispute, one validator (the leader) reads your evidence and asks an AI model for a fair verdict - usually a refund percentage.
Then every other validator does the same thing on their own, without seeing the leader's answer. If most of them land on a similar result (within 15%), the verdict is accepted and written to the blockchain. If they disagree, a new leader is picked and the round repeats.
Because the answer comes from many independent AIs agreeing - not one company's decision - it's much harder to game.

How appeals work
You have 7 days after a verdict finalizes to appeal it. Open the verdict page and click Appeal, give your reason, and optionally add new evidence.
An appeal triggers re-evaluation by a larger set of validators with a stricter agreement bar, which makes the second verdict harder to overturn. The judge re-runs consensus on the same on-chain evidence and stamps the outcome with its consensus round; the appeal manager finalizes only from that round-bound contract state — the outcome is never supplied off-chain, and a result recorded for one round can never finalize a different round's appeal.
Appeals can escalate: once a round finalizes, either party may open the next round (within the same 7-day window). Every round adds 2 validators and tightens the agreement bar, and every round's outcome stays permanently on-chain — the appeal page shows the full round history.
This works in all four dispute categories: every specialist judge — rental, marketplace, sourcing, and delivery — stores its evidence on-chain and can re-run appeal consensus over it itself.

Dispute categories
Beyond disputes
Suggested Products
The same validator consensus that settles disputes also powers a curation feed. The product-suggester contract fetches roundup pages from an owner-approved allowlist of trusted review sites, each validator independently extracts the top products with an LLM, and the picks are accepted only when the validators' lists agree.
Every suggestion is published on-chain with its source link and timestamp - browse them on the Suggestions page.

Where this is going
Roadmap
Shipped phases are facts; future phases are intent and may shift with GenLayer's own roadmap. Full detail in ROADMAP.md ↗.
Core dispute resolution
Four dispute categories behind a single registry, leader/validator AI consensus, IPFS evidence, and live consensus tracking - all on-chain.
Trust & platform layer
Appeals with a 7-day window, user reputation, fraud pattern detection, and platform analytics - each with its own contract and page.
Curation (Product Suggester)
Validator-consensus product picks from trusted review sites, live at /suggestions. Next: home-page surfacing, scheduled auto-refresh, and more trusted sources.
Real settlement
Escrow so verdicts actually move funds: buyer money held at purchase and released per the refund split, with bonded appeals to deter abuse.
Production hardening
Dispute-state notifications, a security review before any value-bearing deployment, and GenLayer mainnet when the network launches.
Open platform
A marketplace SDK/API so other platforms can plug in disputes, community governance of trusted domains, and new dispute categories.
Questions
FAQ
How long does a verdict take?+
Usually 2–6 hours, sometimes up to 24h depending on validator availability and how much evidence there is to fetch.
Can I appeal a verdict?+
Yes - within 7 days of finalization, in every category. Open the verdict page and click "Appeal". The judge re-runs validator consensus on the same on-chain evidence with a stricter agreement bar, and the result is recorded straight from round-bound contract state. Once a round finalizes you can escalate to the next round: each round adds 2 validators and tightens the bar.
Is my data private?+
Evidence is stored on IPFS, which is public. Don't upload sensitive personal data - only what's needed to prove your claim.
What is GenLayer?+
A blockchain where AI validators independently read evidence and reach consensus on the meaning of a dispute - not just on bytes.
How do validators agree?+
Each validator independently reads the same evidence and asks an LLM for a verdict. They agree if their refund estimates land within 15% of each other.
What does it cost?+
Only the network gas for your dispute transaction. On test networks, grab free GEN from the faucet - there's no platform fee.
What are Suggested Products?+
A curation feature, not a dispute. The product-suggester contract fetches roundup pages from an allowlist of trusted review sites, validators independently extract the top picks with an LLM, and the consensus result is published on-chain at /suggestions.
