What is consensus?

We all agree on somethingthe Two Generals’ ProblemPaxos is a consensus protocol in an unreliable networkRaft is an alternative to PaxosBitcoin

a thought experiment meant to illustrate the pitfalls and design challenges of attempting to coordinate an action by communicating over an unreliable linkwikipedia

The Two Generals’ Problem

Solutions

Paxos Super complex Few implementationsRaft Simple, tons of implementationsTrusted peers, Sybil Attack

Bitcoin fights Sybil with Proof of Work. Yay! But is wasteful :(

Enter the Blockchain

Ethereum

running “contracts” on virtual machinecontract = code and stateself executing and inforcing turing complete

Two ways to interact with Ethereum

LocallyQuery valuesrun a program and examine its outputnothing saved

GloballySave values to blockchainCommit a transaction (run program)global consensus

This is important, remember this!

Artificial Intelligence (Almost)

What is a perceptron?

The perceptron algorithm dates back to the late 1950s; its first implementation, in custom hardware, was one of the first artificial neural networks to be produced. (wikipedia)

Tim that wasn’t artificial intelligence. Not even close.

13

Who cares?

14

email: tim@we-are-prot.com | twitter:@readevalprint

Answer: You do.

15

Practical applicationNeural nets can compute any function*Universal Approximation TheoremCommunity trained intelligence Local usage maintains privacysiri calls home, shame *continuous

email: tim@we-are-prot.com | twitter:@readevalprint

Answer: Your kids do.

16

Can a deterministic system have self awareness?If general artificial intelligence is developed and run on a censorship proof networkWho can stop it? See also: AI in a box

Bonus question

Remember before: Local interactions can be purely ephemeral. Global transactions are committed.Equal to parallel dreams indistinguishable from reality but never remembered. Would local instances have rights? Is it ethical to run without committing results?
