Talk given in London on Ethereum and how it fits into Web 3.0 or the Post-Snowden web.

1. ethereumethereum
The
ethereum
Experience

3. ethereumethereum
Universal transaction ledger
Protocol determines:
order
meaning
in terms of state change

4. ethereumethereum
Arbitrary state stored between transactions
Arbitrary state changes due to transactions
thus
Provides arbitration & enforcement for
agreements with arbitrary mechanics

5. ethereumethereum
In short
The Crypto-social-contract.
or
Crypto-Law

7. ethereumethereum
Proof-of-Concept V
Significant changes
Ether sale

8. ethereumethereum
Proof-of-Concept V
Web-Tech API
Mutan, Serpent, LLL
Explorer, Debugger
Out soon!

10. ethereumethereum
Significant Changes
Caller pays
Blockchain rent
Contracts as objects (no EXTRO)
Proof-of-Work

11. ethereumethereum
Contracts as objects (no EXTRO)
Cleaner contract inter-op
Sell data in Ethereum as a service

12. ethereumethereum
Proof-of-Work
General-purpose computation
Memory-hard
ASIC would be Ethereum transaction processor
:-)

13. ethereumethereum
Ether sale

15. ethereumethereum
Ether sale
Bear with us
“2 weeks out”
(80% chance it'll happen in a month)

Days

19. ethereumethereum
Problem
Underlying technology predicated on:
Trust (in “authorities”)
Centralisation & specifity

20. ethereumethereum
Trust
Cost of Meddling: ~£0
(Marginal) Cost of Attacking: ~£0
If you must trust, trust people, not orgs!

21. ethereumethereum
Centralisation
Easily made
Easily broken (into)

22. ethereumethereum
Solution?

24. ethereumethereum
Honesty.

25. ethereumethereum
Divide, conquer and be honest
Public? Spread far & wide.
Private? Encrypt, (sign,) spread far & wide.
Agreed? Sign, form consensus, spread far & wide.
Always, automatically, between ourselves.

26. ethereumethereum
Different technology for different interactions:
Publication & distribution
Messaging & bulletins
Agreements & relationships

27. ethereumethereum
Act 3.0

28. ethereumethereum
Web 3.0

30. ethereumethereum
Swarm Publication & distribution
Whisper Messaging & bulletins
Ethereum Agreements & relationships

31. ethereumethereum
Swarm
P2P
as always!
Data sharing
a bit like BitTorrent
Semi-permanent, any size of data.

33. ethereumethereum
Swarm
More agile
Peer-steering & adaption
More secure
Encryption, possibly onion routing
Better incentivisation
Zero-trust logging of contributions

35. ethereumethereum
Whisper
Messaging
Think UDP
Transient publication
Think broadcast
Configurable TTL
Not strictly async or sync

36. ethereumethereum
Whisper
Peer network spreads all message data
Nodes optimse peers to optimise & repair network
Secure
Private content always encrypted
Dark
Messages routed probabilistically based on attributes
Fast/durable trade-off
Shorter-lived messages routed ahead of more permanent

40. ethereumethereum
Ethereum
State of Affairs
Account balances, reputation, …
Agreements
Contracts, unfinished business
Archival
“What happened for it to end up like this?”

41. ethereumethereum
All together...

44. ethereumethereum
Compared to what you know...

46. ethereumethereum
An example:
Marketplace

53. ethereumethereum
No “authorities” to trust.
No centralisation to fail.
Just individuals cooperating under agreement for
mutual benefit.

54. ethereumethereum
Advert is public.
Transction is private.
Payment is agreed.
Just like Real Life.

55. ethereumethereum
The Experience!

56. ethereumethereum
Goals same as always:
Usable
Information-rich
Ease of interaction

57. ethereumethereum
The past...

58. ethereumethereum
Bitcoin

59. ethereumethereum
Multibit

60. ethereumethereum
Great, but it's just one app.
