The document discusses the challenges of developing decentralized applications and proposes an integrated development environment called Mix. Developing DApps is difficult due to the need to debug across different environments like Ethereum, Whisper and Swarm, as well as different programming languages like Solidity and JavaScript. Mix aims to solve this through deep integration between its components for documentation, testing, compiling, debugging, blockchain state, transactions, deployment and source code management to provide a unified experience for developing DApps.

1. The IDE: “Mix”
What and Why

2. Problem
Writing software is hard, but...
We have processes (e.g. Kanban, Unit testing)
We have services (e.g. Github)
We have technology (e.g. Git, debuggers)

3. Problem
Writing ÐApps is hard.
Diverse debugging env (eth, shh, bzz, more?)
Different languages (Solidity, JS, …)

4. What’s Happening?

5. What’s Happening
The many protocols
Ethereum
...need to debug with blockchain in specific state
Whisper
...need to debug with Whisper having particular messages available
Swarm
...need to debug with Swarm having particular data available

6. Solution?
Integration, integration, integration!

11. Documentation
integration
... for as-you-write documentation health
and preview

12. Test integration
...for as-you-write information on tests passed and reasons for failures

13. Compiler integration
...for as-you-write information on code
health, valid invariants, code structure
and canonical code formatting
Debugger integration
...for as-you-debug annotation on
variable values and assertion truth
.

14. State integration
...allow testing and debugging with arbitrary
State(s)/Blockchain(s)
Transaction integration
...for testing & debugging particular method
combinations
Blockchain/Swarm
integration
...one-step deploy

15. Git integration
...for TODOs, undo stack, time management
Contract repo integration
...for external contract usage and documentation rendering

16. Github repo integration
...for file/resource management, distribution
Github issue integration
...for task/feature/project management, collaboration
