This lesson explores the pivotal components of Hedera, clarifying its functionalities and the importance of its HBAR token, while also drawing interesting parallels to traditional finance constructs. Understanding these elements is essential for anyone looking to navigate the increasingly intricate realm of digital currencies and decentralized applications.

Core Concepts

  1. Hashgraph

    • Traditional Finance: A Hashgraph is a distributed ledger technology similar to blockchain, primarily designed for secure and swift transactions. In traditional finance, the concept revolves around efficient information sharing among parties.
    • Crypto Context: In the crypto world, Hashgraph offers advantages over traditional blockchain systems by avoiding the “blockchain trilemma” of scalability, security, and decentralization. It does this by using a directed acyclic graph (DAG) structure.
    • Importance: For newcomers to crypto, understanding Hashgraph is crucial as it showcases an innovative alternative to conventional blockchain limitations.
  2. Nodes

    • Traditional Finance: Nodes in a financial network refer to individual participants such as banks or payment systems, performing functions crucial to transaction processing.
    • Crypto Context: In Hedera, nodes are software programs that run on computers, maintaining transaction history and the ledger.
    • Importance: Knowing how nodes operate helps newcomers to understand the decentralized nature of blockchain technology.
  3. Proof-of-Stake (PoS)

    • Traditional Finance: PoS is akin to how decisions in a cooperative or shareholders’ meeting might be made, where power is distributed according to ownership.
    • Crypto Context: In Hedera’s implementation, users stake HBAR tokens to validate transactions, thereby influencing network decisions.
    • Importance: This concept is fundamental in illustrating how different cryptocurrencies manage security and validate transactions.
  4. Consensus Mechanism

    • Traditional Finance: Consensus in traditional finance might involve regulatory approvals or auditing processes to confirm transaction validity.
    • Crypto Context: Hedera’s consensus mechanism allows transactions to be validated when two-thirds of nodes agree, a more efficient process compared to the 51% needed in blockchains.
    • Importance: Understanding consensus mechanisms is vital for grasping how trust and security are maintained in decentralized networks.
  5. Gossip Protocol

    • Traditional Finance: Gossip in finance refers to market rumors affecting stock prices and investment decisions.
    • Crypto Context: In Hedera, nodes communicate frequently to share transaction updates, mimicking the spread of gossip for reliable data dissemination.
    • Importance: This concept highlights how information flows in decentralized systems and keeps all participants informed.
  6. HBAR Token

    • Traditional Finance: The HBAR token is akin to a currency used in transactions and services, much like how fees are paid in traditional finance.
    • Crypto Context: HBAR is the native currency of Hedera, necessary for executing transactions and staking.
    • Importance: A thorough understanding of HBAR is essential for anyone engaging with the Hedera platform, as it ties directly to the network’s operational success.

Key Steps

1. Understanding Hashgraph’s Structure

  • Key Points:
    • Unlike traditional blockchains, Hashgraph uses a directed acyclic graph (DAG) for transaction ordering.
    • It addresses the blockchain trilemma by excelling in decentralization, security, and scalability.
  • Detailed Explanation: Hashgraph’s unique structure allows it to efficiently manage transactions without sacrificing speed or security, making it an attractive option for fast-paced digital economies. In contrast to blockchains, which frequently compromise one aspect for another, Hashgraph aims to surpass these limitations.
  • Parallels to Traditional Finance: Traditional financial systems must balance various competing interests, much like how blockchain platforms struggle with trade-offs.

2. The Role of Nodes

  • Key Points:
    • Nodes maintain the network’s integrity and share transactional information.
    • Anyone can set up a node, contributing to decentralized management.
  • Detailed Explanation: Each node records transactions and communicates with others to keep the ledger updated. This openness fosters a democratized network environment where anyone can contribute, much more so than traditional financial systems that often require authority or expertise to participate.
  • Parallels to Traditional Finance: This mirrors stock exchanges, where brokerages rely on decentralized participants for execution and reporting of trades.

3. The Consensus Mechanism

  • Key Points:
    • A two-thirds agreement among nodes is sufficient for transaction validation.
    • This is more efficient than the traditional 51% requirement in blockchains.
  • Detailed Explanation: This method enhances transaction speed and reduces the risks associated with centralization typical in some blockchain networks. With less consensus needed, Hedera can process thousands of transactions per second.
  • Parallels to Traditional Finance: Think of this like stakeholders needing to agree on business decisions, where too many voices can lead to gridlock.

4. The HBAR Token and Its Importance

  • Key Points:
    • HBAR is required for transaction fees and securing the network.
    • Fixed transaction fees make financial planning easier for developers and businesses.
  • Detailed Explanation: The predictable cost of transactions ensures that users can interact without fearing sudden price spikes, which can be a common pitfall in other cryptocurrency platforms.
  • Parallels to Traditional Finance: Just as businesses factor in transaction costs in traditional economics to maintain efficient operations, so too should crypto projects simplify fee structures.

What is Hedera Hashgraph? HBAR Review (2024 Updated) 
https://www.youtube.com/watch?v=5gqfUx9wgoI
Transcript:
 Imagine Hedera as a public network, much like the internet or those blockchain systems we discussed before.  But instead of relying on blocks, Hedera leverages a cutting-edge technology called Hashgraph.  This approach to data management is like a fresh take on how things are verified,  using a system called proof-of-stake to reach consensus.
 I know that might sound like a mouthful, but don’t worry. By the end of  this video, you’ll have a clear understanding of what it all means. Welcome to Whiteboard Invest,  your number one go-to source for clear and concise investing knowledge explanation.  Here, we break down complex financial concepts using a simple whiteboard format,  making learning about investing accessible  to everyone.
 In this video, we’ll be diving deep into Hedera Hashgraph.  We’ll explore what it does, how its HBAR token functions, and meet the minds behind its development.  By unpacking these elements, including the tokenomics, we’ll equip you to make informed  predictions about its future.  Let’s hit the ground running.
 The internet, like a giant public forum, allows anyone to contribute and share information freely.  Most folks have a general grasp that the internet is essentially a platform for exchanging information.  The inner workings of the internet might be a mystery to most users, and that’s perfectly fine.  After all, you don’t need to be a mechanic to drive a car.
 Just like enjoying a smooth ride, using the Internet doesn’t require  a deep dive into its complex mechanisms. The Internet wasn’t always this  user-friendly content creation platform. Thankfully, technological advancements  have paved the way for smoother and easier building and sharing online.  Hedera is crafting a set of tools aimed  at simplifying the process of building on a novel type of decentralized network known as Hashgraphs.
 So this brings us to the first big question, what is a Hashgraph? Delving into Hedera’s  functionalities requires a grasp of Hashgraphs, the underlying information sharing technology  that powers Hedera’s operations.  For those acquainted with blockchains, you might be aware of the so-called blockchain trilemma,  a conundrum involving decentralization, security, and scalability.
 The blockchain trilemma essentially highlights the inherent challenge for blockchains  to excel in all three aspects simultaneously.  Typically, a blockchain can optimize two of  these aspects at best, leaving the third one compromised. Hashgraph technology, however,  claims to circumvent this trilemma.
 Unlike blockchains, Hedera utilizes a unique technology  called a directed acyclic graph, DAG, to order transactions on the network. This distinct approach supposedly allows  them to achieve all three aspects of the trilemma. The inner workings might be intricate, but for  those familiar with IOTA, Hedera shares some similarities.
 Similar to proof-of-stake blockchains,  Hedera leverages a network of nodes that anyone can participate in by running a node,  contributing to the overall health of the network. By now you might be scratching your head. leverages a network of nodes that anyone can participate in by running a node, contributing  to the overall health of the network. By now you might be scratching your head.
 What exactly is a  node? In simpler terms, a node is a software program that resides on a computer and is  responsible for storing and updating both the network’s transaction history, the ledger, and  its current state. So theoretically even you could contribute to the network by running your own node.  Now the magic of Hashgraph lies in its ability to ensure every occurrence on the network, be it a  transaction, a message, a smart contract, or any other form of data exchange,  finds its way into the ledger. Each event recorded on the Hashgraph ledger
 carries four crucial pieces of information. A timestamp, pinpointing the exact moment the  transaction entered the ledger. The transaction details, the specific nature of the transaction  itself. A unique fingerprint of the previous message. This fingerprint, called a hash,  acts like a digital signature for the most recent  message created by the node.
 Another fingerprint, similar to the previous one, this hash identifies  the latest message from the node that relayed the current transaction. These four elements work  together to create a secure and transparent record of everything happening on the Hashgraph network.  To simplify things, let’s imagine a phone call as an event on the Hashgraph. When you call your  friend, the phone logs the time you receive the call.
 During the  call, you might tell them about a cool new video game you bought, transaction  content. You might also mention you called your brother earlier to share the  same news, linking to previous event.  Just like this phone call analogy, every event on the Hashgraph ledger captures four key details – the time it happened, the content itself, and references to past events that tie everything together.
 In essence, a Hashgraph operates like a meticulous record keeper, meticulously tracking all the information  exchanged between each participant or node on the network. It maintains a comprehensive history of  every message sent and received, ensuring that no event goes unnoticed.
 This is essentially what a  hashgraph does, but imagine there’s a little privacy involved. It tracks all the information for each person, or node, they interact with.  So, let’s say you call your friend, just like before.  The hashgraph logs the call, timestamp, and the content.  You mentioning the new video game.  But instead of mentioning you called your brother first,  you might tell a white lie and say it was your sister.
 Modified transaction content. The hashgraph would still record who you actually interacted with, your  sister, but it wouldn’t expose the details of your conversation or the identity of the person you  might be trying to keep private. This becomes a real sticking point, especially when dealing with  money.
 Imagine you’re trying to snag that  limited edition sneaker online, but someone else swoops in and claims they bought it first.  How do you know who’s telling the truth? Now, the beauty of the hashgraph lies in preventing  that sneaker snafu. Here’s why.
 Your sister, whoever she talks to next everyone they all get the same information each message carries a timestamp  acting like a receipt this timestamp proves your call with your sister happened before you or she  spoke to anyone else essentially every person on the network just like everyone in our phone  call example receives a copy of these events This ensures everyone has the exact same information,  eliminating any confusion about who gets the limited edition kicks.
 While Hashgraph shares some similarities with blockchain, there’s a key difference.  Unlike blockchains, Hashgraph keeps the actual content of messages under wraps.  It uses a technique called hashing, which scrambles the message  content into a unique code.
 This way, everyone on the network knows a message happened, like  seeing a call log, but they can’t decipher the details of the conversation itself, like  the content of the call. This adds an extra layer of privacy to the network. We mentioned  IOTA uses a similar technology called a DAG.  Remember how I explained everyone gets a copy of events on a hash graph?  IOTA takes a different approach.
 They rely on a central figure called a coordinator to verify transactions  and ensure there’s one smooth flow of information.  Now, this coordinator is a bit of a hot topic.  Some say it makes IOTA less decentralized than a true dream team. It’s like having a referee on the field, making sure things  run smoothly, but some folks prefer a completely player-run game.
 Hedera tackles this similar  challenge with a twist. They call it the gossip protocol. Imagine a network of friends constantly buzzing with the latest news,  just like middle school gossip.  That’s essentially how Hedera’s nodes operate.  Each node shares transaction data with others,  spreading information throughout the network just like juicy gossip flies through the hallways.
 This constant communication ensures everyone stays on the same page  and prevents any  misinformation from taking hold. All this juicy gossip gets scrambled into secret codes, similar  to how we might whisper secrets in middle school. These codes are called hashes, and the way they’re  connected forms a special kind of network, a directed acyclic graph. DAG for short.
 That’s why Hedera cleverly named  their system Hashgraph. It perfectly captures the essence. A network of whispers, hashes,  forming a connected structure, graph. But what about those pesky lies and manipulations that  could potentially spread like wildfire through this gossip network. Can Hedera handle fraudulent  transactions or misleading gossip? Fun fact, in Hedera’s gossip world, only two-thirds of the  nodes need to agree on the information for transactions to keep flowing smoothly.
 That’s  different from blockchains, where a whopping 51% majority needs to be on the same page.  This 51% number is a big deal in crypto circles because  folks worry about bad actors taking over the network. Luckily, no one’s managed to pull off  a 51% attack yet. Now, let’s shift gears and meet the minds behind Hedera Hashgraph.
 It’s not just a fancy technology. It’s a company headquartered in Dallas, Texas.  The story starts with Lehman Baird,  the genius who invented Hashgraph, and his partner in crime, Mance Harmon. Together,  they brought Hedera Hashgraph to life. As I mentioned earlier, Hedera isn’t just the brainchild  of two individuals. It’s a collective effort backed by 39 impressive entities. You might recognize some of these big names.
 Google,  Boeing, IBM, LG, and Ubisoft are just a few. These heavyweights have joined forces to support  Hedera’s vision, bringing together their expertise and resources to fuel its growth.  Unlike some shadowy organizations, Hedera operates with complete transparency.  The board of directors and  management team are all doxxed, meaning all their information is readily available for anyone to  check out. No anonymity here. They play it straight up.
 Hedera’s mission is crystal clear,  to empower developers worldwide. They’ve built a toolbox of services on their core Hashgraph network, making it a  breeze for anyone to create applications. Their goal? To fling open the doors and make this  powerful technology accessible to everyone, everywhere. Hedera throws down the gauntlet  at blockchain. They believe it’s too sluggish, too complex, and simply not secure enough for widespread use.
 Hey, whether you agree  with that critique is a whole other story. In their eyes, Hashgraph technology is the answer,  offering the speed and security that blockchain seems to lack. Hedera’s services are like a magic  wand, simplifying the use of their Hashgraph technology. They’re all about making it easy for anyone to jump in and start building on their network.
 Hedera offers a developer toolkit with three key services.  The Consensus Service. This acts like a digital notary public,  permanently recording and ordering messages on the Hashgraph with timestamps.  The Smart Contract Service  This is a developer’s dream come true.  It lets them build programs using familiar solidity code,  making it easy to create powerful applications on the Hedera network.
 The Token Service  This service is all about transactions.  It empowers applications to seamlessly handle  all their financial interactions within the Hedera ecosystem. Hedera’s services are like a public  park, open to everyone. You don’t have to be a tech guru or own a fancy computer to use them,  and even if you wanted to run your own node, which isn’t possible yet, you wouldn’t need to.
 Hedera is already buzzing with activity.  Hundreds of applications are up and running, from dApps, decentralized applications,  to cutting-edge stuff like stablecoins, decentralized exchanges, and even NFT  marketplaces. The developer scene is hot, with some folks even building games on the platform.  A major perk of Hedera’s EVM, Ethereum Virtual  Machine Compatibility, is that it makes it a breeze to port Ethereum-based applications  over to the Hedera network. This opens up a world of possibilities, allowing developers to leverage
 the power of Hedera’s superior speed and security without starting from scratch. The HBAR token is the lifeblood  of the Hedera network, powering both transactions and network security. It’s  like the digital fuel that keeps things running smoothly. Users pay transaction  fees in HBAR and those fees are then distributed to the network’s node  operators who are responsible for maintaining and securing the system.
 This process, called staking,  ensures that the network remains robust and reliable. It all boils down to this. HBAR is  the native currency of Hedera, just like you need dollars to shop in the US or Ether to use the  Ethereum network. Think of it as the gas in your car. You need it to keep things moving on Hedera.  Unlike some cryptocurrencies that rely on complex puzzles to secure their networks , Hedera takes a different approach.
 They use a system called Proof of Stake,  where users with more HBAR tokens have a greater say in validating transactions.  It’s like having a vote on the  network, and the more skin in the game you have through holding HBAR, the more weight your vote  carries. Heads up for crypto veterans familiar with proof-of-stake.
 Hedera’s version is a bit  different. Unlike some systems where bad actors can get their tokens slashed, basically punished  for misbehaving, Hedera doesn’t have that mechanism  with HBAR. It’s an interesting point that big tech companies haven’t adopted slashing in their  proof-of-stake systems.
 Perhaps it’s because the idea of punishing misbehaving actors by slashing  their tokens isn’t as effective as it seems in theory. After all, if the goal is to deter bad  behavior, wouldn’t it be more  efficient to focus on preventing it in the first place? That’s where Hedera’s approach,  which emphasizes reputation and network governance, might have an edge.
 Adding to the concern,  Hedera’s own documentation suggests that it might only take a third of the network to pull off an attack.  That’s a worrying thought, especially considering the potential consequences of a successful attack.  Hold on. There’s another twist to Hedera’s staking system.  Unlike traditional proof-of-stake, where you directly participate in validating transactions,  Hedera uses a system called deleglegated Proof of Stake. Here’s the deal.
 Instead of voting yourself, you delegate your voting power to one of the mainnet nodes,  those big companies we mentioned earlier. Remember the 39? So, in essence, you’re trusting one of  these major players to cast your vote on your behalf.
 The key thing to understand here is that you don’t directly cast  your vote on the Hedera network. Instead, you entrust your voting power to one of the 39 mainnet  nodes. In other words, you’re essentially giving them the authority to represent your interests  and make decisions on your behalf. When it comes to processing transactions and tokens, Hedera is a real speedster.
 With its unique consensus mechanism, Hedera can handle up to 10,000 transactions per second.  That’s blazing fast compared to many other blockchain networks.  Now, let’s put Hedera’s impressive speed into perspective.  Ethereum, one of the most popular blockchain networks, can only process around 12 transactions per second with its current infrastructure.
 That’s a significant difference, highlighting Hedera’s ability to handle a much higher volume of transactions.  Get this. Transaction fees on Hedera are unbelievably cheap and stable.  They’re fixed at a mere 0.01 RON, regardless of the HBR price or network traffic.  That’s unheard of in the crypto world.
 This means you can transact on Hedera without worrying about  crazy price fluctuations or skyrocketing fees. Even though transaction fees on Hedera are  denominated in HBAR, they’re always pegged to a fixed value of zero to  ozo on dollars this means you’ll never have to worry about unpredictable fee fluctuations  regardless of hbar’s price movements the hbar token first hit the scene in 2018 through a  private funding round here’s the kicker there will only ever be 50 billion HBAR tokens created, ever.
 This limited supply is called a total supply cap. Right now, only about half, around 23 billion  tokens are circulating. That means there will likely be some inflation for a while, as more  tokens are gradually released into the market.
