The document is a presentation about blockchain technology for Scala developers given by Marcin Gosk at the Scalar conference on April 7, 2018. The presentation introduces blockchain as more than just cryptocurrency, discusses how blockchain works using peer-to-peer networks and cryptography, and demonstrates how smart contracts and CQRS can be used with blockchain. It also shares sample code from a todo list blockchain application.

Blockchain for scala lovers
- 1. Blockchain for Scala lovers Marcin Gosk mgosk@block11.tech Scalar conference 7 april 2018
- 2. Why it is for me ? 1. blockchain != cryptocurrency (bitcoin) 2. Makes many ideas workable 3. Hottest technology in startup world 4. Rising Scala ecosystem
- 3. Presentation plan 1. Some theory - As Short As Possible 2. Live demo – As Soon As Possible
- 4. How it works ? – P2P
- 5. How it works ? – chain of blocks
- 6. How it works ? – cryptography
- 7. How it works ? – smart contracts & blockchain 2.0
- 8. How it works ? – events and CQRS • Blockchain store and process events (eg: transactions in cryptocurrency) • Blockchain use CQRS concept inside • You need to handle unconfirmed events somehow • You can realativly easy move your CQRS app into blockchain
- 9. Show me your code // https://github.com/mgosk/todo-blockchain object HelloBlockchain { def main(args: Array[String]): Unit = { println("Hello, blockchain!") } }
