Doroidotchi - The Tamagotchi-like Smart Contract

I've wanted to sit down and get a bit more familiar with ethereum and Solidity, but I tend to do best with an idea to pull off. Although it's a big job to be involved in the financial revolution, sometimes you just need something silly to hack out in an

Hey, can I see your yellow badge?

The Yellow Badge is a mark found on some of the most tired, stressed, and driven patrons of DEF CON. These people walk with a purpose, talk with a coarse throat, and are always eager to share what they have been working on (assuming nothing is on fire at the

Cryptocurrencies

Coin Canaries

Knowing when a breach has taken place is extremely important - nobody in an organization will begin to react appropriately if everything appears to be running smoothly. Unfortunately, it can be quite difficult to actually detect, at least until it's too late. Our hot wallet sure is running low! Time

Generating Addresses in PostgreSQL

During my initial dirty-hack of the coindroids system for defcon/defcoin, we took a lazy step and just pre-populated an address table with a boatload of addresses generated outside the system.

Giving some Fucks

Thanks to sites like Coingen [http://coingen.io], creating your own altcoin is a pretty simple process to initiate. As the owner of the domain fuckcoin.com, I was happy to see somebody create just that, Fuckcoins [http://fuckco.in]. My lifelong dream of a domain name actually paying off

Deploying an Electrum Buildpack to Heroku

Long story short, I had an idea for a project but no real time to make it happen. Rather than let my initial research go to waste, here are the steps I took to get the Electrum [https://electrum.org] Bitcoin client running on Heroku [https://heroku.com]. Warning## Storing
