SF Bitcoin Devs Seminar: Distributed Consensus Systems with Reality Keys

1. A walk-through of the different approaches to getting information about the external world into a distributed consensus system, including:

• Alt-coins with their own distributed consensus about facts (Truthcoin, SchellingCoin etc)

• Signed data feeds (for Counterparty, Ethereum etc)

• Transaction-signing oracles (Codius, the "BitEthereum" concept)

• Hash-locking

• Conditional key release (Reality Keys)

2. Worked examples using Bitcoin and Reality Keys, featuring:

• Using non-standard branching transactions

• Creating atomic transactions

• Creating stealth keys using ECC arithmetic

• Combining keys to make standard transactions
