Called It
Log what you expect to learn before a course, then prove how much you actually grew.
Keep a private log of what you read and watch, then sell anonymized slices only when you choose.
Try it live, freeYour USDC is locked in a smart contract, not sent to us. We can only collect it by delivering before 28 Oct 2026. If we miss it, you take it back yourself from My apps, no permission needed. We can also refund you any time. View the contract on BaseScan.
Promised delivery: 28 Oct 2026 (counted from payment).
Add-ons are not part of this payment. Once your app is delivered you can request them from My apps, and you only pay if you say yes to the quote.
Leo realizes brands profit from his browsing. Attention Ledger stores his history encrypted locally, and he opts in to sell aggregated topic slices to researchers for USDC, revoking anytime.
Local capture extension, encrypted vault, consent receipt contract, buyer request board
Reshape it entirely: new features, your flows, your brand end to end, integrations you need. We scope it with you.
Per-buyer consent data sales exist as a hackathon prototype; an individual-held attention log with revocation is uncommon.
Vana DataDAOs pool user data, Brave Rewards pays for ad attention, and Consent Protocol (HackFS) let users choose which data to sell and to whom.
Checked with web searches in October 2026. A search is not proof that nothing similar exists, and the market moves fast, so we recheck before every build.
User-owned data theme; eligibility unknown
The complete Attention Ledger app: members keep an encrypted log of what they read and watch on their own device, sell anonymized cohort averages only under their own rules, and revoke any licence, with a paywall and crypto checkout built in.
Every buyer gets the same finished app. Basic branding and copy changes come through a quick form.
Your admin side: revenue, paywall editor, users, rules and the agent log.
Referral and growth mechanics, switched on when you are ready to grow.
Keeping a ledger and saying no are free. Members can go Pro for deeper tools, research labs pay for buyer seats, and the owner takes a small fee on each slice sold.
The owner keeps a 10% fee on each slice (adjustable), halved for Pro members. Gas for receipts is under $0.01 and can be sponsored.
Prices are yours to set. Illustrative, not a promise of income.

Custom work from $3,000: your own topic taxonomy, a buyer agreement flow for your jurisdiction, integration with a lab's survey tool, extra languages or a white label panel for a university. Scoped on a call.
The recipe (how it is built, the data, costs, risks, build order, the pitch and the demo script) is unlocked when your app is paid in full.
People's browsing and watching history is already sold by ad networks and data brokers, without their say or a share. Some people would gladly help research with anonymized averages, on their own terms, but have no private way to keep the log, set rules and revoke.
Vana DataDAOs pool user data for AI training, Brave Rewards pays users for viewing ads, and Consent Protocol, an ETHGlobal HackFS project, let users choose which data to sell and to whom. What we did not find is an individual-held attention log, kept encrypted on the person's device, that answers buyer requests with aggregated slices under personal rules and supports revocation. The consent selling idea exists as a prototype; the on-device ledger with revocable licences is the uncommon part.

Make a person's attention theirs to price, lend and take back, so research can learn from it without anyone being watched.
A mirror of your week Every Sunday the ledger shows where your hours went. Most people come for the mirror, not the money.
Saying no feels good Watching the agent refuse an ad broker on your behalf is a small, satisfying moment of control.
Revocation is real Taking back a yes with one tap, and seeing future deliveries stop, builds trust that keeps people opted in.

Cost per use: unlocked when your app is paid in full.
Users share their weekly mirror and refusals. Researchers who get useful slices post more requests, which draws more users who want to be part of studies they care about.

Nine routes from one vessel. Tap a port to open its chart.
Every ad network already sells a slice of what you read and watch; you just never see the money or the buyer. Attention Ledger keeps a member's history encrypted on their own device and lets them sell anonymized topic slices to researchers only when they say yes, with a consent receipt onchain and revocation any time. Owning it means you run the consent marketplace: your brand on the extension, your buyer relationships, and your platform fee on every consented sale.
The capture extension, encrypted vault, consent receipt contract and buyer request board are built. You brand it, deploy from your wallet with the guide and publish the extension under your name. Expect a few extra steps for the browser store listing.
Consent based sales of anonymized, aggregated data can be lawful, but privacy law varies (GDPR, state laws and others). Before your first paid sale, get a privacy lawyer to review your terms and buyer agreements. Never sell raw histories.
Many will not, and that is reasonable. Publish exactly what is captured, keep data encrypted on device, open source the extension if you can, and start with people who already know you.
Academic researchers, market research firms and media studies groups who need consented panels. Start with one researcher you can reach personally.
Small amounts at first, often a few dollars a month. Be honest: it is about control and fair pay, not income replacement.
Buyers pay per consented data slice; members receive most of it and you keep a clearly disclosed platform fee. Researchers can also pay a monthly subscription for panel access.
Illustrative stages, not a forecast. Results depend on you and the market; nothing here is guaranteed.
