Bitcoin Graffiti

a museum of data stored in the blockchain work in progress

Blocks 0–965,470 · every artifact verified against the chain

A timeline of data stored in Bitcoin

Every Bitcoin transaction carries fields that can hold arbitrary bytes, and for as long as the chain has existed people have used them to store things meant to outlast any server: photographs, source code, love letters, protest anthems, leaked documents, prayers, insults. The ledger is replicated by every node and can never be edited, so whatever goes in stays in.

186artifacts catalogued
164rebuilt from raw bytes
2009–2026years spanned
📦 Archive bulk corpora, searchable: 64,024 Coinbase1,610 P2FKH3,607 P2FMS browse the archive →

Every artifact below has been confirmed against the chain, and 164 have been rebuilt from their raw bytes so you can see the file itself rather than a description of it. Read the timeline top to bottom, browse the gallery by type or by method, or open the Archive for every readable message found in blocks 0–965,470 (September 2026).
