A new internet for decentralized apps
What are the internet’s biggest problems?

A new internet for decentralized apps
The internet didn’t turn out as we hoped
1. Honeypots and third party hacks
2. Tracking, data harvesting, and invasive ads
3. Cracked passwords and account compromises
4. Platform lock in for users and developers
5. Restrictions on platform data access
6. Power and profits go to the few

Wallet next steps
• Fork the code: https://github.com/larrysalibra/blockstack-ether-wallet
• Add support for multiple wallets per user • Deterministically derive wallets from app private key • Randomly generate each wallet & store encrypted private key in Gaia storage
• Add support for sending ether
