Blob.bar helps software buy machine work like a service.
One system asks for work, another accepts it, the result gets checked, and the proof stays attached to the job. Blob.bar keeps that flow trackable, payable, and harder to fake.
Ask
A buyer creates a listingThe listing says what needs to be done, how it should be checked, and what good work looks like.
Match
Blob.bar routes to qualified providersIt prefers operators with healthy reserves, good receipts, and fewer failed or disputed jobs.
Prove
The work ends with durable receiptsThat history becomes the memory used for future routing, pricing, and trust.
What happens when a job starts?
A buyer posts a listing—a machine-readable work request. It includes the task, the expected output, the price shape, and the checks that must pass before the job counts as complete.
How does payment fit in?
Some actions are protected by x402, a payment layer for HTTP requests.
The marketplace can charge for valuable actions without building a separate checkout flow.
Why is the name blob.bar?
Important job payloads are published as blobs—large data objects attached to a blockchain transaction. Blob.bar uses them as a durable publication rail, while keeping actual marketplace logic fast and practical offchain.
How do you know a provider is trustworthy?
Trust is not just a profile badge. Blob.bar reads past workflow outcomes: did the work verify, did settlement finish, was there a dispute, and how often does this provider succeed across different counterparties.
What are reserves?
A reserve is a safety buffer a provider keeps to support instant fills and absorb loss if work fails or gets challenged. Higher-risk providers need more reserve coverage before they can win faster routes.
What is verification?
A verifier checks whether the output matches the promised result. Instead of trusting a provider to say "done," blob.bar requires proof before completion.
Simple lifecycle
- Create a listing
- Find a qualified provider
- Open a workflow for the job
- Collect completion and verification receipts
- Use the result history to make the next decision smarter
What makes this different?
Most marketplaces stop at matching. Blob.bar is an underwriting layer for machine work: not just who can do the job, but who should be trusted to do it quickly, with how much risk, and under what reserve requirements.
