Notable Quotes
Bitcoin Design
It turned out that basically it exists in this narrow design space where anything much different breaks it and makes it less efficient.
Adam Back @adam3us
Layer 2 Revolution
Layer two is really revolutionary because... you can build any functionality you can think of on a higher architectural level.
Tuur Demeester @TuurDemeester
Risks to Bitcoin
The biggest risk is complacency is just losing track of the cypherpunk values that made this project come to life in the first place.
Tuur Demeester @TuurDemeester
Anti-Fragility
The anti fragility is the users and the activist investors who will make a noise... We are the anti fragility.
Adam Back @adam3us
Future Institutions
Building institutions in the meat space is one of the challenges for bitcoin for the next five, 10, probably 100 years.
Tuur Demeester @TuurDemeester
Game Theory Scaling
Bitcoin's game theory seems to scale in the sense that what worked for people mining bitcoin on laptops... seems to continue to work with increasingly large private company miners.
Adam Back @adam3us
Bitcoin vs. Gold
Let's see if bitcoin can compete with gold on a market cap basis. We are... only 10 times away.
Adam Back @adam3us
Cultural Depth
I don't think you can stick a thousand bitcoiners on an island and it's going to turn into some kind of citadel... I think you need a lot more cultural depth.
Tuur Demeester @TuurDemeester
Addressable Market
Hal Finney... thought the addressable market for Bitcoin was $200 trillion. Is thinking big, that's $10 million a coin.
