0x0f. Introduction to Hyperledger Sawtooth [Blockchain Developers Meetup]

On our last monthly blockchain developers meetup, we had Arian van Eersel introducing us to Hyperledger Sawtooth.
The date of our meetup this time was also very interesting – the 11th anniversary since the first Bitcoin whitepaper was released on 31.10.2008 by Satoshi Nakamoto.
