  3. 3. : Bitcoin is neither good nor bad nor is it neutral It certainly can’t be un-invented and it also won’t wait for doubters IT’S TECHNOLOGY
  4. 4. BITCOIN FOR THE USER: WALLETS AND EXCHANGES
  5. 5. ‘JUST’ THE FIRST APP ON THE BLOCKCHAIN: CASH MONEY OVER THE INTERNET

  7. 7. THE INTERNET OF PROPERTY Bitcoin will make property flow like the internet made content flow
  8. 8. No single point of failure/control/censorship Not every centralized function had/has a decentralized counterpart, bookkeeping now does NOT JUST A DATABASE BUT DECENTRALIZED
  9. 9. Key to understanding the blockchain is understanding ‘decentralisation’
  10. 10. BITCOIN BEHIND THE CURTAINS: CRYPTOGRAPHY, ALGORITHMS AND MINING
  11. 11. BITCOIN: BLUEPRINT FOR CRYPTOCURRENCIES
  12. 12. REAL INVENTION IS THE BLOCKCHAIN Every bitcoin node is equal and (in principle) - runs the same program - has the same, full copy of the ledger Very effective, resilient and scalable but also: - massive redundancy and inefficiency Current implementation is not up to ‘the’ task: - slow (confirmations take 10m) - limited (transaction volume) - too large for true distributed use (ledger is 42TB currently)
  13. 13. BLOCKCHAIN A decentralized, internetted ledger that makes any property (including money) ‘cash’, transparent and undisputed Allows transactions to be done without the need for trust or third parties. It is (like cash money) a true peer to peer solution. Simple functionality, complicated technology
  14. 14. DECENTRALISED AUTONOMOUS CORPORATIONS Algorithmic companies that run on millions of computers at the same time, without a single point of failure, control or censorship. NEW BLOCKCHAINS: VEN SMARTER LEDGERS, OT JUST DATA, CODE TOO
  15. 15. LA’ZOOZ: ‘UBER’ IMPLEMENTED AS A DAC
