Natal 1½d, Edward VII, c.1902
The Witness
March 28, 2025.
At 17:26 UTC, a file began uploading to a decentralized storage network. No announcement. No thread. No launch party. Just a transaction — and a decision to say nothing.
The network’s epoch counter read 1. The very first epoch of Walrus mainnet — Sui blockchain’s permanent storage layer. The data was distributed across independent nodes worldwide, erasure-coded across a hundred storage operators. As long as a third of them remain honest, every byte is recoverable. Perfectly. Forever.
Sixty stamps. One complete pane. Each scanned at 4,800 DPI — files ranging from 90 to 150 megabytes each. Every perforation tooth. Every paper fiber. Every microscopic variation in a printer’s ink from 1902. The full pane alone: over a gigabyte, nearly five gigabytes encoded on-chain.
The stamps are from Natal. British colonial postal history. King Edward VII. 1½ penny denomination, issued 1902. They predate the formation of South Africa by eight years. Pristine — mint condition, original gum, virtually no toning, perfect perforations. A complete pane, intact.
Nobody knew. That was the point. The timestamp is on-chain. It cannot be changed, backdated, or forged. The chain witnessed it before anyone else did.
Epoch 2.
One year later: here we are.
The Collection
The complete pane.
Ten rows, six columns. Every position documented, every stamp scanned individually. Click any stamp to see its Walrus record. The blob IDs below are not marketing — they are addresses on a permanent network where the actual scan lives.
The Record
What does “permanent” mean?
Walrus is a decentralized storage network built on Sui. It uses erasure coding — the same mathematics that underlies deep-space communication — to distribute data across a hundred independent storage operators. No single operator holds your data. No single operator can delete it.
It is not IPFS. It is not a hard drive with a backup. It is a cryptographic commitment, made on a public blockchain, that this data existed at this moment. The on-chain certificate is the proof. Anyone can verify it.
Each stamp scan has a Walrus blob ID — a content-addressed identifier derived from the file itself. If one byte changes, the blob ID changes. The blob ID in the chain is the scan. They are the same thing.

Authentication
A physical stamp carries its own fingerprint: the precise geometry of its perforations, the distribution of ink under the paper fibers, micro-variations in the gum on the reverse. At 4,800 DPI, these are visible. A forgery cannot reproduce them without possessing the original. The scan is the reference. The chain is the notary.
Tooling for direct scan comparison is in development.
