Intro to Decentralization


Over time the internet became highly centralized

1. Blind trust in others

2. No ownership of data

3. Bad for innovaMon

4. Bad for security


The Benefits of decentralization

For users:

1. OpMons

2. Availability

3. Savings

4. InfoSec

For developers & society:

1. Inclusion

2. InnovaMon

3. Independence


…but decentralized apps are hard to build

1. Complexity

2. Security

3. Scalability
