Crypto 101 | VIDEO: Andreas Antonopoulous: Advanced Bitcoin Scri...

Andreas M. Antonopoulos is an early pioneer, adopter & educator in the Bitcoin/Crypto space if you have not heard of him.

He routinely puts out some of the best information going. He speaks plainly and simply with some humour!

-- Andreas' Logo he uses for his branding, he is fun. That is the top of his head, looking down.

LOL.

He travels the world preaching the Bitcoin, Liberty, Crypto and Blockchain gospel and is one of the most well respected lecturers and teachers in the crypto world!

I always include a library of AA's videos in these posts, just like he does in every one of his YT channel videos. These are things for you to use, save, watch, share, and learn from if you have time now or come back to later if you wish. It's here to help you, with extra resources.

This resource showed up in my email inbox recently, have a watch, share it with those who are learning.

This is the first part of a more technical talk where Andreas explores Bitcoin script, with examples from the 2nd edition of Mastering Bitcoin, focusing on the use of conditional statements, flow control, guard clauses and time locks.

The examples will include advanced multi-signature scripts, hash time lock contracts and asymmetric revocable commitments.

Then he answers questions about Bitcoin's quirky bugs, where Bitcoin differs from Ethereum at a scripting level, how SegWit works, how consensus rules change, and whether Bitcoin is more than just a currency.

This talk took place at the San Francisco Bitcoin Developer (@SFBitcoinDev) meetup on April 3rd, 2017: https://www.meetup.com/SF-Bitcoin-Dev...
