BITCOIN LAND 101

Before you buy digital land, understand exactly what it is. No hype — just how inscriptions, the first-is-first rule and listings actually work on Bitcoin.

01 · THE RAW MATERIAL

WHAT IS AN INSCRIPTION?

An inscription is arbitrary data written into the witness of a Bitcoin transaction and attached to one specific satoshi. Once mined it cannot be edited or deleted.

A Bitmap inscription is deliberately boring: it is a plain text file containing something like 840000.bitmap. The value is not the file — it is the fact that it was the first one.

Because the data rides a sat, ownership follows that sat. Whoever controls the output holding it controls the inscription.

02 · THE ONLY RULE THAT MATTERS

HOW FIRST-IS-FIRST WORKS

Bitcoin does not know what a Bitmap is. Bitmap theory is a convention layered on top: for each block height, the earliest inscription whose text is <height>.bitmap is the valid claim on that block.

Anyone can inscribe the same text later. Those inscriptions exist forever, but they are duplicates with no claim — this site marks them as invalid and shows how many were made.

Child claims follow the same rule: <index>.<height>.bitmap and the number of valid parcels can never exceed the transaction count of that block.

  1. 10:02 · 840000.bitmapVALID
  2. 10:41 · 840000.bitmapINVALID
  3. 14:07 · 840000.bitmapINVALID

> FIRST INSCRIPTION FOR A BLOCK WINS. EVERY LATER CLAIM IS A DUPLICATE.

03 · DON'T CONFUSE THESE

INSCRIPTION VS BITMAP VS LISTING

Inscription — the on-chain artifact. It always exists, valid or not.

Bitmap — the accepted claim on a block, derived by applying first-is-first across every inscription. This is the asset.

Listing — not on-chain property at all. It is a partially signed Bitcoin transaction from the holder, offering the inscription at a price. No custody, no escrow: the signature is the listing, and it settles only when a buyer funds and broadcasts it.

  • INSCRIPTION
    the data on a sat
  • BITMAP
    the valid claim on a block
  • LISTING
    a signed offer to sell it
04 · WHY IT IS CALLED LAND

BLOCKS, PARCELS AND BUILDING

Each block becomes a plot whose interior is drawn from its real transactions — the mosaic you see on every bitmap page is packed from actual transaction sizes, so no two look alike.

A bitmap can be subdivided into parcels, one per transaction in that block, each its own child claim with its own owner.

Holders can build on their land — info pages, galleries, shops and 3D worlds — or lease it out to builders instead of selling.
