Birth of a DApp
Early hacking via Remix or similar tools
- Quick prototyping Solidity playground
- Slow compilation, cumbersome workflow ¹
Test driven via Truffle or similar tools
Integration of a DApp
Deployment on Ropsten or similar network
- Real-world behavior, multi-user environment
- Live integration, user feedback, launch preparation
Perfect environment... until it goes boom 💥
- Heavy chain due to frequent spam attacks ¹
- Unstable chain due to occasional reorg attacks ²
- Unfriendly chain due to limited test ETH availability ³
¹ Raiden 😇 ² Rinkeby / Kovan ³ Faucets
Run your own network?! 😱
Mixed bag of treats
- Yay – Light, stable, unlimited and shareable
- Noo – Need to deploy, monitor and maintain
- Omg – Genesis (per client), ethstats (auth, bans)
- OmG – Bootnodes (firewall) and signers (accounts)
- Omfg – Explorer, wallet, faucet, guides, website, proxy
Uhm... yeah... hmm...
