| Video Discription | On November 20, 2017, Leemon Baird, inventor of hashgraph, spoke at Harvard Business School, giving a comprehensive overview of the consensus algorithm, while taking questions from the audience of students. Leemon first compares the four generations of blockchain technology and then gives a deeper dive into gossip about gossip and Virtual Voting. Timestamps for this video 0:00 Intro 1:03 What is hashgraph? 4:12 How fast is hashgraph? 6:31 How secure is hashgraph? What does asynchronous byzantine mean? 12:23 How fair is hashgraph? (Fair access, fair ordering, & fair timestamps) 16:43 Distributed ledger technology (DLT) generations and their use cases. 26:45 How does the hashgraph algorithm work? 29:59 What incentivizes individuals to gossip? 32:23 Gossip protocol, the fastest most resilient way to get a message out. 33:50 How does hashgraph prevent double spend? 34:43 Consensus for free with math guarantees - gossip about gossip. 40:59 Virtual voting 43:50 How does the number of hashes scale with the number of nodes in the system? 45:53 Can hashgraph be used for a public ledger on a large scale? 48:04 When pitching this technology to enterprises, how do you differentiate hashgraph from traditional blockchain? 50:39 What is the target market that would benefit from hashgraph? 51:26 What is next for hashgraph and why haven't traditional blockchain technologies deployed gossip about gossip or virtual voting? 53:10 What is the value proposition for a game like World of Warcraft? 55:15 How does hashgraph differ from conventional blockchain and how do you get enough users on board for the system to function properly? 57:07 Proof of work and forking. 1:01:08 There are 51% AND 34% attacks on any blockchain/DLT. 1:07:20 How would the cost of a 51% attack differ from a 34% attack? 1:08:32 What kind of transactions per second has hashgraph achieved? 1:10:03 What is the potential (current and future) for the banking industry regarding this technology? 1:12:58 Will there be an ICO? 1:13:45 What is your main product and business model? 1:16:35 Are smart contracts possible? 1:17:24 Will hashgraph swallow up the competition? 1:17:56 Does hashgraph compete with Bitcoin and Ethereum? 1:20:25 Closing and Thanks Telegram: https://t.me/hashgraph Whitepaper: http://www.swirlds.com/downloads/SWIRLDS-TR-2016-01.pdf SDK: http://www.swirlds.com/download #LeemonBaird #Hashgraph #GossipAboutGossip |
