The problem
Provenance without a mark
Thousands of teams build on Ethereum. None of them share a way to say so. Intel solved this for chips in 1991: a small mark inside someone else's product that made the invisible layer legible. Ethereum's invisible layer has no equivalent.
The move
One lockup, no permission
Two rows of bordered cells in a monospaced grid. The slashed zero and the trigraph E carry the provenance; the border makes it a stamp rather than a logo. Anything made on the network can wear it, the same way the network works: without asking.
Form
A stamp, not a logo
Bordered cells read as certification. It sits on a product the way a hallmark sits on silver: small, factual, checkable.
Type
Machine voice
Monospaced caps, the alphabet of infrastructure. The slashed zero is borrowed from terminals, where ambiguity is a bug.
