What does sharing a journal accomplish?

More than people credit. A shared journal is how coaching actually works: someone experienced reads your trades, sees the pattern you cannot see, and tells you. At $29.95/mo^[1] a month — $359.40 a year — Tradervue is a serious tool for that, and kappi does not compete with it, because kappi is not a review product at all.

Where does a shared link stop working?

The moment the reader has an incentive to doubt you. A coach reading your journal is helping you; a prop firm, an investor or a prospective subscriber is deciding whether to risk something on you, and they know the document was assembled by the person it flatters.

Ask what a reader can independently establish from a shared journal. Not whether the trades happened — they may well have. Not whether the numbers add up — they probably do. The unanswerable question is when each row was written, and that is precisely the question that separates a track record from a scrapbook.

Broker-import journals prove what you did after the fact, from data you control. kappi timestamps what you said you would do, before you knew how it would turn out, on a record you cannot edit.

What "verifiable" means here, concretely

Every sealed commit is hashed into a Merkle tree and anchored to Hedera, so the log is append-only and independently checkable.

So the reader does not have to trust kappi either. They check the Merkle root against a public ledger and confirm that the log they are reading is the log that existed at that timestamp. A link that requires trusting the platform has only moved the trust problem one step.

Can you keep trades private and still prove them?

Yes, and that is the reason a recorder is not simply a public journal. Your notes and your trades stay yours until a time of your choosing. A commit is timestamped and sealed the moment it is made, so precedence is fixed immediately, but nothing is readable until you let it open. You decide when it becomes public; you cannot change what it says.

Nobody front-runs a sealed commit, because there is nothing readable to front-run — and the same seal is what stops you rewriting the entry once you know how it went.

When should you pick Tradervue?

When you want review, tagging and reporting over a large fill history, or when a coach or trading group works inside it. Those workflows are mature there and absent here. If nobody is asking you to prove anything, the honest recommendation on this page is the journal.

When should you pick kappi?

When the audience is a stranger. $15 a month, $12.75 through a referral link, and no free tier. At $180 a year against $359.40, running the recorder costs $179.40 less than the journal — but the reason to choose it is what the link means, not what it costs.
