For tipsters, creators and anyone claiming an edge
Seal your own record
The machinery on this site does not care whose predictions it measures. Send us yours before kickoff and they go into a hash chain under exactly the same rules as ours — sealed, anchored, never rewritten — and the record is published whichever way it goes. That last part is the whole offer. Anyone can show you a screenshot of a winner.
What you get, precisely
The same rules as ours
One chain per person, under guests/<you>/. Each entry carries
the SHA-256 of the one before it, gets an OpenTimestamps proof anchored into a
Bitcoin block, and is verified by the same standalone
verifier anyone can run against your chain without
installing anything. First publication wins. Nothing is ever rewritten, including
by you.
Measured by closing line value
Your price against the market-average closing price for the same selection. CLV is the accepted evidence of edge and it converges in hundreds of bets where profit is still noise. Flat-stakes profit and loss is shown too, labelled as the noisier number. Where a sealed Asian-handicap line and the closing line differ, the entry is settled and shown but no CLV is claimed — unlike lines are not divided as though they were the same bet.
What you do not get
No editing. No deleting a bad week. No "since I changed my approach" restart. No ROI headline. If you seal a month of losers, this site publishes a month of losers under your name, and the point of coming here is that a reader knows that before they look.
Coverage
Anything football-data.co.uk publishes a closing price for — around forty competitions across Europe and beyond, well past the 11 divisions our own model prices. A selection with no closing benchmark cannot be given CLV and we will say so rather than invent one.
How it works today
Deliberately manual, and worth being straight about: there is no submission form yet, because there is no guest yet and building the form first would be building the wrong thing. You send an entry before kickoff — a message is enough — and the operator runs one command. The chain and the anchor do the rest.

That is the whole entry. Pick and price, sealed before the whistle, nothing else — no reasoning to be judged on, no stake to be argued about. Your entry is timestamped when we receive it and it is graded from the first publication.
Nobody has done this yet
There is no guest record on this site, and rather than leave that to be discovered we would rather say it on the page that makes the offer. The code is written and tested, the rules above are the rules, and the first person through the door gets the first chain. If that is you, the terms are the same as ours: free, public, and not editable afterwards.
Why you might not want this
Worth saying plainly, because a page that only lists reasons to say yes is the sort of page this site exists to be the opposite of.
It can only hurt a bad record
If you do not have an edge, this will show that, in public, permanently, and there is no mechanism for taking it down. That is not a side effect we are apologising for; it is the product.
It is slow
CLV converges faster than profit and it is still not fast. A few hundred entries before the number means much, which is months of ordinary volume. Nothing here will settle an argument this week.
