Meeting Notes
- Today we're joined by guest Kris Stinson (@StinsonKris on Twitter)
- Lots of media attention, "blockchain this, blockchain that", they're trying to sell you a database
- Microsoft, IBM, governments (even Canada: Cancoin)
- Banks are threatened, unregulated currency (scary!)
- Japan has approved Bitcoin as a currency (legal tender)
- Legal (tax) ramifications: Capital Gains.
Video
- We watch a video with Andreas Antonopolis: Foremost educator on Bitcoin Blockchain for Beginners - YouTube
Types of blockchain currency
- CryptoCurrency Market Capitalizations
- Augur - a "betting" site; deals with contracts
- Based on Ethereum
- DAO - Decentralized Autonomous Organization
- eg. Ethereum
- A decision by this DAO split Ethereum into Ethereum and Ethereum Classic
- Now there are miners working on both branches of the blockchain
- "The mining network" determines whether a fork of the blockchain can happen
How does the blockchain determine "truth"?
- The longest chain wins
- "Rolling back the chain"
- database
- miners
Quantum computers?
- Will change the game!
- Winkelvoss brothers
- Own over 50% of bitcoin?
- This is a problem, they can determine the validity of transactions
Wallets
- Wallets are Public/Private Key encryption containers
- How to get a Bitcoin Donation buttton on our Non-Profit Organization website?
- Just need to publish your wallet's Public Key, no "button" required
- But Shifty Button | ShapeShift | The fastest way to swap cryptocurrencies. No account required
- This will generate a button for multiple currencies;
- Just copy 'n' paste your public wallet address
Other blockchain technologies
- Don't trust The Cloud?
- Authentication
- Filesystems
90 minutes was far too short to cover all aspects of Blockchain Technology; we'll invite Kris Stinson back someday.
