Using PGP signatures with bitcoin script OP_CHECKDATASIG

Dr. Mark B. Lundeberg, 2018 August 30 bitcoincash:qqy9myvyt7qffgye5a2mn2vn8ry95qm6asy40ptgx2

Since version 2.1, GnuPG is able to use the very same secp256k1 elliptic curve signature algorithm (ECDSA) as used in bitcoin. Quite soon Bitcoin Cash will add a new script opcode OP_CHECKDATASIG that is able to check signatures not just on the containing transaction, but also on arbitrary data. For fun, let's try to intersect the two signature systems and see what can be done!

Screencasting Framework

The following document is a written account of the Code School screencasting framework. It should be used as a reference of the accompanying screencast on the topic.

Why you should care about screencasting?

You're probably aren't going to take the time to read this document if you're not interested, but there are a lot of nice side effects caused by learning how to create quality screencasts.

1. Communicating more effectively - At Envy Labs we produce screencasts for our clients all the time. Whether it's demoing a new feature or for a presentation for an invester, they're often much more effective and pleasent than a phone call or screen sharing.

  case minutes do
    minutes when minutes in 0..1 ->
      case seconds do
        seconds when seconds in 0..4 ->
          "less than 5 seconds"
        seconds when seconds in 5..9 ->
          "less than 10 seconds"

Using MSYS2 with Visual Studio Code is extremely easy now thanks to the Shell Launcher extension by Tyriar.

First, install the extension and reload Visual Studio Code.

Then, open the settings.json to edit your settings.

Add the field shellLauncher.shells.windows. I recommend using autocompletion here so that all the default shells are added.

You should having something like this now:
