This part two of a two part series on muti-signature addresses and wallets. This is important technology for massively improving bitcoin security. In part one we generated a multisig address/wallet. In this part, we'lll walk you through all the steps necessary to spend the funds, going line by line through some simple python code and generating a payment in bitcoind.

In many ways, multisig addresses are the answer to most of bitcoin's concerns and fears of theft. And now its time to scale up massive implementation for them. Originally introduced into the bitcoin client a few years ago, multisignature addresses massively more secure than regular ones. Their adoption by all wallet manufacturers is coming. But, for you techies and voyeurs, we'll jump inside the ideas of multi-sig and even program the stuff. Hope you enjoy.

Bitcoin 101 - Fun with Brain Wallets (Making and Playing With Them) - Bitcoin Security

There's no idea in Bitcoin more science fiction ready than the idea of brain wallets. To actually hold your wealth inside your head (and no where else) is something that can be done only with bitcoins. In this video we set up and play with a number of brain wallets (of course they aren't really brain wallets if we tell everyone the passwords and private keys...but you get the idea). Whether you are a fiction writer or an escaping refugee, this video is for you.

Welcom to WBN's Bitcoin 101 Blackboard Series -- a full beginner to expert course in bitcoin. We hope you enjoy. And remember the official WBN launch is coming up : January 1st, 2014.

Our Notes:  We are working on a much better and safer way to store your private information so that it's extremely hard for anyone to get no matter what.  It has to do with old technology.  Sometimes that is just the best way.

Bitcoin 101 - Getting Your BTCs out of Your Paper Wallets & Cold

Are your bitcoins stuck in cold storage or on your paper wallet? Sure those are both GREAT places to keep them, but how do you get them out? That's the goal of this video. Hopefully by the end of these videos you will no longer be afraid to take your bitcoins out of the reaches of malware programmers.

This is part two of our bitcoin security series. Here's the intro to the series...


Bitcoin security? UGH!!! Way too many bitcoins are being stolen by crafty malware programmers.

Bitcoin does so many things better than banks (trusts, escrows, programmable money, cheap transfers, instant accounts, etc.), but one area that is not quite so nice, is security.

While the bitcoin network, itself, appears bullet-proof, lots of bitcoins are being stolen, via hacking, malware and flaws in online wallets and even google's random number generator.

The answer is to get your bitcoins entirely offline, and the two ways to do this are paper wallets and cold storage. The previous video is an introduction to making both, while this video focuses on how to get your bitcoins out of cold storage (to spend, to move to another wallet, etc).

James walks you through the software and ideas used in making 'sloppy' offline wallets (which are great to have). He also gives suggestions at making even better offline wallets. This is the first of many videos we will make on bitcoin security, and the least technical.

We hope you'll enjoy.

Here's the public address to the wallet we sent the funds too...good luck...hope you get there first.
