Agenda

1. Problems with the internet

2. What is Blockstack?

3. How to build an Ethereum wallet in 3 lines of code

What are the internet’s biggest problems?

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

The problem?

The problem?Centralization!

Imagine

1. No data silos

2. No middlemen

3. No ads

4. No tracking

5. No passwords

6. No lock in

We can do better

with decentralization

How to decentralize?

Move apps & data to the edge of the network

Get rid of servers

What is Blockstack?

Blockstack is a new internet for decentralized apps where you own your data and apps run locally without remote servers.

What is Blockstack?

Blockstack handles the complexity

{ Authentication

Storage

Identity

Naming

Blockchain

App AppApp

Blockstack makes building decentralized apps easy

Without Blockstack With Blockstack

Servers Serverless

Databases Personal storage APIs

Identity management to build Identity built-in

Payment systems to build Payments built-in

No encryption Encryption built-in

No data integrity Signatures built-in

Decentralized, serverless apps A decentralized payment network

A decentralized directory for names, public keys, and pointers to storage locations

Open protocols for identity and authentication

1. Single Page JavaScript ApplicationsDecentralized, serverless apps 2. Bitcoin, Ethereum or Stacks A decentralized payment network

3. Blockstack Core A decentralized directory for names, public keys, and pointers to storage locations

4. Blockstack ID Open protocols for identity and authentication

Make an Ethereum wallet Blockstack app

in only 3 lines of code!

What is an Ethereum wallet?

Public/Private key pair

Address (hash of public key)

Crypto Wallet Challenges

1. On-boarding the user

2. Securely storing the private key

3. Backing up wallets

MyEtherWallet

How would this look on Blockstack?

Blockstack is a better experience for users

Look Ma! Only 3 lines of code!

Blockstack is easier for developers

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
