09:08:37	 From Joseph Chow : (Time 1 seems dangling in these slides)
09:09:01	 From jonchoi : +1
09:10:04	 From lanerettig : BTC POW currently burns as much energy as Ecuador… not a tiny country
09:11:18	 From jonchoi : yep also worth mentioning PoS uses potential value at loss as the incentive as opposed to realized opex in PoW
09:12:04	 From lanerettig : what does “finality” really mean in a world where someone can disagree, rewind, and fork anyway?
09:12:30	 From @M : I think it means they can’t rewind and fork?
09:12:46	 From danny : it would require manual intervention
09:12:53	 From danny : can always fork :)
09:16:09	 From @M : Is Phil’s question presenting a difference between a “protocol changing fork”, and a reorganization which just rewinds and builds on a previous block?
09:19:53	 From aparnakrishnan : Is there any reason for choosing 50 blocks to be the epoch?

    Terms:

Web3.js: A Javascript library letting you interact with any Ethereum node using the RPC network protocol.
Geth: A heavyweight Ethereum node
Testrpc: A Ethereum node simulator (fast and good for development)
Pudding: A library wrapping web3.js providing a nicer interface for interacting with the node/sending transactions.
Truffle: A framework good for JS developers who want to build prototypes and don't mind the restrictions it imposes. For more customization, just use plain JS, web3.js, and pudding.
Solc: The Solidity compiler
