Kai orders the history.
Each accepted addition has a deterministic causal coordinate. New state extends the same original.
Why a baseball card?
Because a season keeps happening.
A player keeps playing. Scores change. Owners change. The card has to carry what happened before—and remain the same original.
That is Receiz continuity you can hold, play, and inspect.
The season moves.
The card remembers.
Plays become verified history. Score, ownership, and the path here stay connected inside the card.

Watch the continuity
A new play. The same original.
A candidate event is ready to join the card’s history.
Illustrated process. No file or account is changed here.
A final score closes the game. The carried play sequence keeps it open to study: build new scouting views, compare patterns, and trace each result back to the recorded plays.

Not a season of waiting.
The browser holds the verified history and shows the part you are looking at. Scrolling changes the view—not what the card knows.

How the whole season fits
Merkle commitments bind the parts.
Verify that history belongs to the enclosing proof object. A hash alone cannot replace that object.
Checkpoints shorten the path.
Fibonacci checkpoints navigate ancestry without replaying every earlier event for every view.
Store the source. Bound the view.
Durable custody keeps the admitted history. The browser renders a small window and realizes media as needed.
The hard part is keeping the whole story
A score is one number.
A season is everything that led to it.
For each player, plays arrive across games. Each admitted event must stay connected to its time, score contribution, card identity, and earlier history. Ownership adds another history that must survive every handoff.
On a phone, the challenge is not just storing those records. It is keeping the complete verified history available without rebuilding it every time you open a card or making the browser render a season at once.
Receiz keeps the source complete and the visible work small. More history does not mean starting over.
What you actually get
The next owner gets the story, too.
Collect the history.
Keep the card’s issue, play appends, ownership, and career history together.
Inspect what changed.
See the verified events behind the current state. A number does not replace its evidence.
Carry it forward.
Export the complete sealed card. Verify its carried history offline, or continue in a compatible reader.
The export carries history through its sealed head. Later games extend it through verified additions. A card’s ownership is distinct from rights to a player’s name, likeness, or media.
The same primitive, beyond baseball
Your work has a next chapter, too.
A new owner. Another project. A different app. The point is the same: carry the original and its verified history into what comes next.
