Confirmation Bias and Bitcoin
... has drawn from a variety of schools of thought: game theory, cryptography, hacker culture, the open source movement and libertarian ideology..
Bitcoin
At it's core, Bitcoin is...
A global decentralised network that allows censorship resistant transfer of value

The internet gave us a decentralised global network that allowed the sharing information
Bitcoin allows us the same with value
This value is secured by cryptography, using an public, append only, blockchain (DTL) maintained by participants and developed by the open-source community
Why is that significant?
- Banking the unbanked
- Remittance markets
- Fight super-inflation
- Protect wealth from unlawful seizure
- Global economies without intermediaries
Fundamental use cases
... and many unimagined use cases

Proof of Work
- PoW Waste = Security of Network
- Synonymous to current systems:
- Vaults, Security Guards, Electric Fencing
- Datacenters, Disaster Recovery Centers
- Counterfeit Preventions
- ...entire Banking infrastructure
Ecological Impact
- Move towards stable green energy
- Huge investments in sustainable computing
- Energy usage not linear to adoption/transactions
- Auto adjusting difficulty
- First a year ran on < 5 computers
- Innovations and protocol changes (PoS, DPoS)
Challenges
- Scaling
- Adoption
- (de)centralisation
- Regulation
- End user security
- User experience
The Future
- Lightning (Instant, Low Fee Payments)
- Rootstock (Smart Contract)
- Tumblebit (Anonymous Payments)
