Bitcoin Icon/Logo

SATOSHI PRESENTS a logo/icon to use for Bitcoin and makes it copyright-free. This is no longer the logo being used by bitcoin. org. The current logo is this:

New icon/logo

Satoshi Nakamoto February 24, 2010 09:24:23 PM

New icons, what do you think? Better than the old one?

The perspective shadow was too thick on the larger sizes. Iupdated 32, 48 and the full size.

I release these images into the public domain (copyright-free). Irequest that derivative works be made public domain.

Excellent. This would be a good resource for thoseparticipating in the banner contest. Why unequal dimensions?

My only suggestion would be to make the coin’s text stand out more. At tiny resolutions outlines tend to be come unworkable, so a better option may be to experiment with contrast. Making the text significantly darker than the rest of the coin wouldlikely increase readability. Alternately, you could make the inner circle color darker, and the text lighter.

Good suggestion. I made the B slightly lighter and the background slightly darker. Very slightly. The foreground is now exactly the same colour as the BC in the old one.

It’s kind of OK if you can’t easily read the B in the 16x16. At that size, you just need to see that it’s a coin. It doesn’t matter so much what’s embossed on it, just that there be some detail therebecause it wouldn’t look like a coin if it was a blank smooth circle.

It’s slightly wider than tall because the dark perspective under it goes more to the right than down.

I finished and posted the 32x31 and 48x47 versions in the first message. I like the 48 a lot.

How does everyone feel about the B symbol with the two lines through the outside? Can we live with that as our logo?

How about an SVG version? That way we could automatically generate smaller and larger versions as needed.

I don’t know how to do SVG, but I did the original very large, over500 pixels across, so it can be scaled down. I’ll give the original when I’m finished.

I had to custom tweak each icon size so the vertical linesland square on their pixels, otherwise they’re ugly blurry and inconsistent. Such is the challenge of making icons. The original will be good for scaling to custom sizes between 48 and 500 but not smaller.

Full size 530x529 image for scaling down to custom sizes:
