Laptop Versus Axe   Message List

Greetings, people of the decentralization group!

Here is the highlight of my presentation at CodeCon last weekend. CodeCon's
prime directive is that every presentation has to have a live demo of working
code, and that the presenter has to be an author of that code.

For my demo, I leaned an axe against the speaker's podium, strapped safety
goggles around my neck, and then I showed three laptops on stage, each running a
Tahoe node, and then uploaded a movie file to the Tahoe grid made up of those
three nodes. (This means the file gets automatically encrypted, digitally
signed, and erasure-coded.)

Then I explained that after uploading your movie to the Tahoe grid, you might
turn off your Tahoe node and go away. And while you are gone, something BAD
might happen...

... That's a very good question. The minimal answer is "Yes". The short answer is that you don't rely on the storage servers for confidentiality (all data is...

That's interesting. Just curious, is it easy to deploy this in a web-facing manner? For example, at Expensify we store a bunch of receipt images. We...
