The document discusses the potential and pitfalls of blockchain technology and cryptocurrency, emphasizing Bitcoin's speculative nature and the various use cases where blockchain may not be necessary. It outlines seven inspirations for decentralization, including identity management, data ownership, and decentralized organizations, while also highlighting threats posed by centralized entities like Facebook's Libra coin. Additionally, it provides guidance on getting started with blockchain technology, primarily through the Ethereum platform.

1. Decentralize all
the things

4. The Dunning Kruger effect

5. blockchain ~= event store
a looooong list of ordered transactions
kept by a huge network, secured by a consensus mechanism

6. 7 inspirations

7. 1. Money & Currency
crypto trading & Decentralized Finance Products (DeFi)
payment transactions
simple, transparent, international
super fast: Lightning network / Raiden
crowd funding, ICOs
3rd world micro payments, credits and banking systems
Stable Coins (DAI, Libra)

8. There are poor ideas,
bad ones and
Facebook's Libra
The Real Threat From
Facebook's Libra Coin

Privacy, Bad for
CompetitionWhy Facebook’s Libra
Cryptocurrency Will Be
ad For Everyone
Why Facebook’s New
Libra Coin is Good — and
Really Bad — for the
World

9. 2. Data
unlock data silos (e.g. Spotify)
decouple data sources from data sinks
create new value chains on data
near realtime, public data distribution
earn tokens for data ingestion
let others make sense of your data
see what Spotify saved about you...
… and only they can utilize! @stadolf

10. 3. Identity
maintain your very own self sovereign identity
let others prove identity fragments by verifiable claims
works across ledgers (DID)
get rid of centralized traceable user profiles
eliminate need for password authentication
only disclose data that’s mandatory for a use case

11. 4. Assets & Ownership
ERC721 / Non fungible tokens (NFT)
proof of ownership
real estate, fine arts, concert tickets, diamonds
IoT: digital twins
ticket markets / maximum price regulations
trading of unique crypto assets
“everything that you consider paying for
has a price and therefore a value”
@stadolf

12. 5. Computation
monetize idling CPUs
perfect for “serverless” computing / FaaS
earn tokens for offering computing resources
spend tokens for using resources
perform computation on encrypted data (!)
@stadolf

13. 6. Organizations
decentralized autonomous organizations (“DAOs”)
organizational transparence
minimal costs of governance
unstoppable (not even by Putin, Erdogan or Trump!)
rules are set by token holder’s votes, stakes and reputation
+ networks of DAOs can control each other
= decentralized jurisdiction (Aragon Court just out!)
@stadolf

15. 7. Society
vote in public elections with your own identity
include people’s opinion on governments’ decisions
move public infrastructure into trusted, uncompromisable networks
healthcare, transport, insurances, ecology, public real estate,...
develop independent solutions
faster, better UX, network effects!
utilize open governmental data
@stadolf

16. Which Governments Are
Using Blockchain Right Now?
How is the UK
government using
blockchain?

19. This is really
going to
happen!

20. Getting started
no need to deeply understand “crypto” or “consensus”
everything meaningful is built on Ethereum smart contracts
+ install Metamask, lookup OpenZeppelin, Solidity, ERC20/721
most things only require frontend skills / Javascript!
understand decentralized storage (and Oracles)
+ IPFS, Arweave, StorJ, Chainlink
earn Open Source bounties on Gitcoin
consider starting with an “out of the box” solution (Blockstack, 3box)

21. and remember Dunning-Kruger...
