Blockchains allow for decentralized trust through consensus and incentives to address issues caused by centralized trust being hacked in the digital world. While the technology is abstract and complex, blockchains represent a revolution in the economy by enabling new applications like cashless remittances, digital identity, and asset tokenization. However, challenges remain around security, governance, custody, regulation, access to talent, and fragmentation as the industry works to develop mainstream applications beyond just currency.

4. Modern Society = Organized/
Centralized Trust against Chaos

5. Digital Society = Centralized

6. ALL HACKED

8. What are blockchains, why do we need
them, why now?
Trust damaged - > Trust disrupted
Chains are computers you can trust
Non centralized - Consensus - Incentive

9. Why is it so (damn) hard to get
and even more to buy in?
Abstract - by devs 4 devs - Noise - Scary - Complex - Early/No visible mainstream apps
Even Bitcoin alone is hard to get (BTC, BCH, BTG, Segwit, 2x…)

10. IT’S NOT THE REVOLUTION
OF MONEY
IT’s the REVOLUTION OF ECONOMY
(well, depends where and when)
We are the protocol age: TCP/IP, FTP, HTTP(s), SMTP, IMAP…..

11. Some Jargon
BCT/XBT, BCH, ETH
PUMP AND DUMP
HODL
EXCHANGE
WALLET
TXN
GAS
SMART CONTRACTS
ICOs
TO THE MOON

16. Store of Value?

17. Time for Dapps?

18. Key Applications
Crypto ownership
cashless remittances
Digital Identity
Collectibles
(physical and non) Asset tokenization

Security - 5
Scale - 3
Governance - 8
Custody - 9
Regulation - 10
Fragmentation - 5
Access to talent - 10
Too much going on - 9
