Their Hashgraph technology uses a protocol called “Gossip about Gossip”. Despite what you may think, “Gossip” is actually a well-known computer technology phrase that refers to how computers communicate with each other. The Hashgraph team describes it as “Calling any random node and telling that node everything you know, that it does not know. In distributed ledger technology the “baseline” or minimum bandwidth required is that the transactions go to every node. Gossip about Gossip refers to attaching a small additional amount of information to this Gossip, which contains the last person we talked to, hence, we are gossiping about the information we gossiped. Using this information, we can build the Hashgraph.” - https://squawker.org/technology/blockchain-just-became-obsolete-the-future-is-hashgraph/ This is the key for how Hashgraph would be able to know exactly when consensus would be reached. Another aspect of the blockchain that Hashgraph is aiming to improve is the relative wastefulness of “stale” blocks and also to radically reduce the computing power needed compared to things like proof of work and proof of stake. There is no doubt that Blockchain technology is a great step forward. But it’s very much worth it to note that it has room to improve. And despite the fact that I am finally beginning to feel confident in my own knowledge of how blockchain technology works, I’m finding myself eager to learn more about other ideas on how it can be improved upon. Swirlds’ Hashgraph isn’t the only platform that’s focusing on changing how a blockchain can be tweaked. Byteball and other cryptos using DAGs are more or less on the same page in regards to their ideas for providing alternative options. These are also called blockchain-free cryptocurrencies. The list of these types of cryptocurrencies includes Byteball, as I mentioned before, IOTA, and DagCoin. Basically, a blockchain-free cryptocurrency is any distributed database that uses different tools to achieve essentially the same objectives as a blockchain. These different tools used include what are called DAGs. This stands for Directed Acyclic Graphs. A quick Google search of this will show you an image of a DAG. If you’re like me and imagery tends to help you understand certain concepts, then take into account the context and imagery of a blockchain, and compare it to the imagery of a DAG. It might be a bit easier to wrap your head around how DAGs can be faster and more effecient in certain ways. Now I’m not ashamed to admit that I’m still working towards understanding this concept better so I welcome anyone who can supplement with additional information on ways to break this down to please leave a comment down below so we can all learn more about it.

What is ZOOKO'S TRIANGLE? What does ZOOKO'S TRIANGLE mean? ZOOKO'S TRIANGLE meaning & explanation
What is ZOOKO'S TRIANGLE? What does ZOOKO'S TRIANGLE mean? ZOOKO'S TRIANGLE meaning - ZOOKO'S TRIANGLE definition - ZOOKO'S TRIANGLE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Zooko's triangle is a trilemma of three properties that are generally considered desirable for names of participants in a network protocol: Human-meaningful: Meaningful and memorable (low-entropy) names are provided to the users. Secure: The amount of damage a malicious entity can inflict on the system should be as low as possible. Decentralized: Names correctly resolve to their respective entities without the use of a central authority or service. Zooko Wilcox-O'Hearn conjectured that no single kind of name can achieve more than two. For example: DNSSec offers a secure, human-meaningful naming scheme, but is not secure against compromise by the root; .onion addresses and bitcoin addresses are secure and decentralized but not human-meaningful; and I2P uses name translation services which are secure (as they run locally) and provide human-meaningful names - but fail to provide unique entities when used globally in a decentralised network without authorities. Several systems which exhibit all three properties of Zooko's triangle have now been created, including: Computer scientist Nick Szabo's paper "Secure Property Titles with Owner Authority" illustrated that all three properties can be achieved up to the limits of Byzantine fault tolerance. Activist Aaron Swartz described a naming system based on Bitcoin employing Bitcoin's distributed blockchain as a proof-of-work to establish consensus of domain name ownership. These systems remain vulnerable to Sybil attack, but are secure under Byzantine assumptions. Namecoin now implements the concept. Several platforms implement refutations of Zooko's conjecture, including: Twister (which use the later Aaron Swartz system with a bitcoin-like system), Blockstack (which can run on any blockchain and currently uses Bitcoin), Namecoin (separate blockchain), and Monero OpenAlias.

EP46: Doing Business with the Dash Blockchain w/ Amanda B Johnson
Welcome back! Topics covered in this episode include: Ron Paul and the Modern Freedom Movement Why “money” and “economics” are important to achieving personal liberty Evolution of Crypto-currencies (Bitcoin vs Dash) How Amanda became the first-ever podcast/vblog to get funding DIRECTLY from a blockchain (and why this is a necessary step towards crypto-economic longevity). Tip Liberty Entrepreneurs with Dash! XyJPi91jEW6Zqz6qXX1qxzqpqDhUwhT3gf (or Bitcoin) 1KraNMPw7QMaaLmHsiMj57QKq9GHvZLKgh Amanda B Johnson started down the rabbit-hole of libertarianism and voluntaryism in 2011. At the time she was struggling to find work and became really interested in what caused the economy to become so crappy. She heard about a guy named Ron Paul who was running for President and was shocked when he sounded like he was speaking the truth. With her new found enthusiasm, Amanda started creating liberty related, Ron Paul videos on Youtube and quickly gathered following. She became fascinated with money and economics and the role they play in pursuit of personal freedom and wanted to share her new found perspective with the world. In 2013, Amanda encountered Bitcoin. Like many of us, she read and studied it with passion and eventually wrote blog posts for several large Bitcoin publications including Bitcoin Magazine, CoinTelegraph, Bitcoin.com. In late 2015, Amanda started a YouTube series entitled The Daily Decrypt, which discussed the currency competition and evolution taking place in the crypto space. By mid-2016, she decided to specialize in one network in particular — Dash — which she finds to be the most technically and economically superior thus poised to gain strength, market-cap and influence. She named the new show Dash: Detailed. Amanda and her colleagues are the first ever podcast or video blog to be sponsored and paid DIRECTLY from the Dash blockchain, or any blockchain for that matter. Someone needs to add this to Wikipedia. A self-funding blockchain this is an evolutionary step for cryptocurrencies. Unlike Bitcoin, the Dash blockchain allocates a certain % of the block-reward (or inflationary payout) to fund projects which help build, support and market their network and is much more business-like in their approach.. Dash: Detailed is showing the world how blockchains and crypto-assets can be used to build and support a voluntary community and economy with a open-source and transparency money.

Masternode Setup, Buying Shares, and 'Interest-Bearing Accounts' of the Future | DASH: Detailed
With a current return-on-investment of 10%+ annually, many are wondering how to launch a Dash masternode. Luckily -- unlike in the world of mining -- detailed information on how to begin is not difficult to come by. But for interested investors who don't own 1000 Dash now and won't in the foreseeable future, what is a protocol-level, decentralized solution for the long term?
