BLUEPRINT

Why it matters and how it really works

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.

The need

Good early calls get lost in group chats and deleted threads, and anyone can claim they said something first. Analysts, writers and ordinary sharp people have no simple, portable way to prove what they said, when, and who stood with them.

What exists and what is new

Pieces of this already exist: Ethereum Attestation Service (EAS) lets anyone sign a dated statement on Base, Zora and Paragraph let writers mint posts, and prediction markets such as Polymarket and Manifold record forecasts with money or play money attached. What is different here is the combination, not a new primitive: a plain-language take with a check-back date, co-signs and linked counter-takes from other wallets, honest weighting of fresh wallets, and a settle-it-yourself track record page, with no betting involved. Novelty is modest; the value is in the format and the habit.

The data it runs on

Unlocked when your app is paid in full

1.The mission

Make it normal to put your name and a date on what you believe, and to be judged on the record rather than on who shouts loudest.

2.Why people can't resist it

Receipts for being early A dated, signed take you can link from your bio ends every 'I told you so' argument.

Bring your people Co-signing takes 30 seconds and puts the co-signer on the record too, so friends share it.

Check-back day The take comes due on a date you chose. Settling it in public, hit or miss, keeps people coming back.

4.Pricing

Cost per use: unlocked when your app is paid in full.

Free $0

Post up to 5 takes a month, co-sign anything, public track record page.

Verified page $15 per month

Unlimited takes, custom domain track record page, export, and a verified badge for analysts and writers.

Community $300 per month

Branded instance for a research group or newsletter with its own take wall, moderation tools and leaderboards.

5.Growth loop

Every take is a link, and every co-sign asks someone to share it. Settled takes produce a screenshot-worthy card. Analysts who build a record link it from their bios, which brings their readers in to co-sign.

8.Where this is going

Now
A barbershop argument gets settled with a signed, dated take and a wall of co-signs.
Next
Analysts and writers link verified track record pages instead of follower counts.
Later
Newsrooms and research groups run their own take walls and publish their hit rates.
Far
Public talk rewards people who are right early and honest when wrong, because the record is open to everyone.

OWNER PLAYBOOK

Own it, then chart your voyage

Nine routes from one vessel. Tap a port to open its chart.

Why own Proof of Opinion

Proof of Opinion lets you put your name on a take onchain, mint it as a shareable badge, and let others co-sign it. Post your calls on a social app and the record can be deleted, buried or locked behind someone else's feed. Own it on Base and your track record of takes, your co-signers and your brand live under your wallet, provable forever.

What’s stopping you?

“I can't code.”

You do not need to. You pick the name, logo and color, and the app is ready to post takes, mint badges and collect co-signs on Base.

“What if my take is wrong, forever?”

That is the point and the risk. A public record of wrong takes is also proof you are honest. Post takes you are willing to stand behind, and add follow up notes when you learn something.

“Will anyone co-sign?”

Not at first, unless you ask. Start by asking 5 people who already agree with you to co-sign your first take. Co-signs grow from people you already talk to.

“Can people use it to post harmful claims?”

It is your instance, so you set the rules. Keep posting open to your community only at first, write a short content policy, and hide badges that break it from your front end.

“Is it really mine?”

Yes. Deployed from your wallet on Base, under your domain. The takes and badges are onchain and not tied to any platform account.
