01 // OCR-Bitcoin
OCR-Bitcoin is based on the OCR-B typeface. It adds Bitcoin symbols and is designed for displaying currency amounts and numeric values with clarity.
02 // History & Cultural Recognition
Fonts have aesthetics, and when used for specific purposes their functional design gains cultural meaning. OCR fonts became tied to balances, serial numbers, values, and money.
By the late 1960s, machines were processing financial documents at scale. OCR-A was introduced in 1966 for machine reading. It worked but was clunky to read. OCR-B followed in 1968, refined for precision and designed to be clear for both machines and humans.

03 // Functional Display
OCR-Bitcoin’s first real-world use is in the Bitcoin Knots logo. It is also integrated into the node client for wallet addresses, currency amounts, and other readouts.
The mock-ups below show how OCR-Bitcoin works as a display font for balances, fees, and transaction data across Bitcoin applications.

02 // What Is a Brand? What Is a Logo?
A brand is what people say about you when you leave the room.
It’s not your logo — it’s your reputation. A logo is a compressed signal of brand/reputation.
One glance unpacks the values, vision, and promise.
It’s like a visual hash.

05 // Font Choice
It's a nod to money.
OCR-A was built in 1966 to do one thing, make money machine-readable.
• Clean enough for humans
• Precise enough for machines
• Standardized by ANSI and ISO
• Used across banking, checks, and ATMs
Plus, it just has that cypherpunk aesthetic.

06 // Why the Slash?
The slash ( / ) is a nod to directory structure used in C++ — the programming language behind Bitcoin.
It represents a path inside the system, a full-node software implementation that’s purely monetary.
Knots is Bitcoin.
And Bitcoin is only money.
