256b on the blockchain

category: general [glöplog]
I have a small fetish for distributed storage and recently came to think about that some of the smaller demoscene productions could fit inside a Namecoin id/-field (max 520 bytes).

In this example I have inserted Circus by Depth into the Namecoin blockchain in a id/ named after the pouët prodnumber (57280). We can now retrieve the prod with this super-simple python script (assuming that the Namecoin software is running on our computer):

Code: #!/usr/bin/python3 # proof-of-concept retrieval of 256b prods from the Namecoin blockchain. import base64 import json import os output = os.popen('namecoin-cli name_show "id/57280"').read() jstring = json.loads(output)['value'] filename = json.loads(jstring)['name'] mybase64 = json.loads(jstring)['base64'] mybase64 = str.encode(mybase64) mybin = base64.decodebytes(mybase64) myfile = open(filename, 'wb') myfile.write(mybin) myfile.close()

This should give us a file in the current directory called circus, 256 bytes in size, that you can run in an Amiga emulator or transfer to vintage plastic & silicone.

Thank you for your time, over and out.

P.S. Works on my machine ;-)

when can we start mining 256byte intros?

Hey, stop it! Kids in Africa could have eaten those prods!

Code:namecoin-cli name_show "id/miner"

...or link: https://namecha.in/name/id/miner

Look for "value". Granted, not a prod, but only took 35 bytes. ;)

Am I the only one worried that the script alone is 446 bytes?
well, how big is the browser you use to download 256b intros?

I'm not a size coder, I'm just a fan :)

hmmm... how big is the BIOS you use to run your 256b intros ?

256b of what?

Any 256b of course. For the example, click the prod link.

secret hint: almost all 256b use more than 256b vidmem!

Cleaned up the scripts for usage by common men and women.

I also inserted https://www.pouet.net/prod.php?which=65455

Indeed! Best usecase ever!
