Dr. Leemon Baird x Harvard Talk - Hashgraph: New Directions for Blockchains & Distributed Ledgers

So you think $100 HBAR with a 5 trillion market cap? Yeah I think that’s easily in the cards within 10 years. Keep in mind that I suspect 5 trillion 10 years from now will be worth 1 trillion dollars right now with inflation still running hot. That’s very doable maybe we get $200 HBAR.

[@kctheservant]

Great video and great introduction! I just have a different view about "the whole purpose of PoW is to make it run slower". You can argue that it is the result: the transaction is slowed down due to PoW, as PoW is required for the permissionless consensus in blockchain-type DLT (at least today's Bitcoin and Ethereum). It is the result, not the purpose. The purpose is more on something else. Just my opinion.

[@Supremax67]

Naw, it is the purpose. If blocks were being completed too fast, you would end up with excessive amount of forks happening. It needs to go at a maximum speed to avoid splits in the chain. If it is not slowed down by design, it would lose all its value.

[@inflashuns4154]

It is the purpose since he explains you slow it down by solving a useless math problem that's hard to solve because you need a large rig with a lot of electricity. What else would be the purpose of this?

@Dr. Leemon Baird; at the 28min 30sec mark of this viedo, a question was asked which has been mine and is one I can't explain fully since following Hashgraph back in 2016, and from all these videos and white papers I have read on Hashgraph this is the closest you have come to explaining but didn't finish in this viedo. "How does a node KNOW what the node it is about to gosip to KNOWs, before it gosip to it in one way communication; without first comparing each node's version of the hashgraph (which would require multiple transactions and increased bandwidth)". The best I have come up with is the parent node will tell the child node in the gossip workflow everything it can see that the child node can't based on what the parent node can see in their version of the hashgraph they have at that point of time. Which could be telling them some overlapping information they already know but not a lot. The other idea is when one node gosips to another; the child node then gosips back to the parent before moving on. It is also unclear to me how a node would deal with gosiped information from a malicious node that suggests gospi order is different to the nodes version of the hashgraph? Does hash proofs solve this? Can you please do a viedo explaining the "very cleaver ways" Hashgraph nodes can work out what the nood it is about to gosip to KNOWs before it sends gosip information to minimise network traffic and data transfer, which keeps Hashgraph as efficient as you describe in this presentation. Love the "third party algorithm" problems you are solving with Hedera Hashgraph, big fan and love hearing you talk about the mechanics of how Hashgraph works. Keep up the amazing efforts and progress! 🔥

[@dactoanho6026]

The flaw is How do you have the same timestamp reference across the nodes? Now we have to use the NTP hardware with GPS to synchronize the timestamp across the nodes

[@HederaHashgraph]

Hi Dac Toan Ho ! Thank you for the comment. It is a MEDIAN timestamp taken from the entire community. If a node was acting maliciously it could set his internal clock at year 1940, or maybe year 2550. An assumption is made that most members are honest. (We also have to have 2/3 honest nodes for the system to reach consensus - but theorems say this is the best any DLT can be). This is an extremely accurate system. Follow us here: t.me/hashgraph hashgraph.com swirlds.com or hashgraphboard.com Thanks!

[@jayp6955]

So we're going to have islands of private servers that all use their own private blockchains? So the internet isn't going to change, and it will remain centralized? Make the software public, let people spread it like the good virus it is.

[@alexandermearle]

"Gossip about gossip is unprecedented" Excited to see how this DLT platform will integrate into many different industries. It was painful to hear some of these questions. I suppose they are the college of business. But most of the questions indicated no real understanding of block chain protocol and how it's slower then gossip about gossip. I would have thought Harvard college of business would have done their homework.

[@kdanagger6894]

How do you agree on a "good" timestamp? This seems like a MAJOR venerability. Different network latency times between nodes could make it impossible to determine the actual time of an "event".

[@Supremax67]

You need to visit the simple explanation of Hashgraph video. You made a lot of unfounded assumption here. To begin with, you only need more than 2/3 of the nodes to come to consensus, which will also sort the order of the transaction using the median timestamp. Nodes going offline does NOT affect the consensus, neither can a node manipulate the time they came to consensus. You are watching a video on a proven technology. Swirlds has already demonstrated Hashgraph in action.

OPEN SOURCE AND BLOCKCHAIN MIGRATION Will it be released as OPEN SOURCE and when? And will there be some kind of MIGRATION of the current blockchain cryptocurrencies to Hashgraph or Billions of invested dollars will be lost and the TRUST of millions of investors around the World. For example, Bitcoin migrates to Hashgraph and offers 1:1 coin exchange. This will secure Billions in investments Worldwide.

[@SpruceGumRules]

What's the overhead to do the virtual voting? It is a math problem albeit relatively fast compared to proof of work.

[@Supremax67]

Minimal because it is computational while the gossip is bandwidth. So while Gossip is happening, the virtual voting is being cast simultaneously. The bottleneck is the internet, even though I wouldn't call 250k trx a second a bottleneck.

[@TadasTalaikis]

[@jayp6955]

These gossip diagrams remind me of Minkowski space-time diagrams.

[@mbharatm]

How does the protocol take care of inaccurate timestamps or clock sync issues between all the nodes in the graph?

[@patricksweeney556]

It is determined as the median time of the transaction as reported by all nodes. Which means any inaccurate outliers have a negligible effect on the accuracy of the consensus timestamp.

[@loiccartilier6019]

I have two questions: is this censorship resistant? and does it have any privacy attributes?

[@Supremax67]

It supports all functions of privacy, including KYC, PDI, GDPR, etc. What the network is essentially is, it's an algo, not a blockchain. What you build on top of the algo cannot be observed by a 3rd party unless the company itself decided to disclose what they were using it for.

[@Federerking]

I have a question : can alt coins who run blockchains now convert their technology toward harshgraph in the futur if they want to without stepping back from the progress they made previously ?

[@Federerking]

Christopher Corsi Sadly no :/

[@andrewmcdermott2394]

Yes they can I believe it’s just about plug and play with ethereum projects

[@surferboy198]

smart contracts (solidity) for example are possible to run on Hashgraph. They already built this service. But if you built natively on HCS (hedera consensus service) you don't need these slow smart contracts. There is enough information in the HCS that can easily replace smart contracts. Hedera just launched a new service called "scheduled transactions" which is essentially just that. hedera.com/blog/announcing-scheduled-transactions-on-hedera, Leemon made a video over here aswell: kzbin.info/www/bejne/i32blmV3i8mGZ9k

[@jayp6955]

It is better to raise only as much as you need, privately, and release your blockchain to the public only after you have tested it in a controlled environment. You will create a "singularity" when you go public with your coin, because there will be a ton of pent up demand. Is there a way for a developer like myself to get in on this project early? I guess it can't be mined or anything -- but it would be nice to put a stake in the project, or at least play with the development API or SDK or whatever. Do you have a bounded token sale? This is a great way for hobbyists to get tokens, without risking a blow-up valuation in your project.

He is a great teacher, but he confuses them around the 38/40th minute point by making it sound like he's sending the whole history when he is assuming (correctly) that the nodes involved all have the accumulated state (hashes) all along the way already, which is why the two extra hashes 'connect' the current message(s)/transactions to the previous accumulated state. Very interesting, but he missed a chance to illuminate a couple of the people asking questions at that point.
