What's Hedera?

Hedera Hashgraph (or just Hedera) showed up in 2019. It runs on something called Hashgraph consensus. Instead of the usual blockchain way of doing things with blocks, Hashgraph uses a gossip system and virtual voting to sort things out. This means it's really fast, makes things fair, wraps up transactions quick, and keeps everything secure.

In 2024, the folks at Hedera got the patents for Hashgraph and made the code open source with the Linux Foundation's Hiero project. Cool, huh?

Cool Tech Stuff

Speed: Hedera can do over 10,000 transactions per second (TPS) when it's running smoothly. Also, transactions are done in just 3–5 seconds. That's way faster than Ethereum.

Transaction Costs: Fees are steady and super cheap (around $0.0001 per token transfer). And it's carbon-negative, making it much better for the environment than power-hungry blockchains like Bitcoin.

Services: Hedera gives you three key services using APIs and SDKs.

Smart Contract Service: Run Solidity contracts quickly and cheaply.

Token Service: Create and handle tokens easily (both standard and unique ones) with rules.

Consensus Service: A dependable way to track events. It works well for businesses and IoT stuff.

How It's Being Used

  1. DeFi, Payments, and Small Payments: Hedera makes super-quick, cheap transfers doable, which is awesome for payments, sending money, and helping out online creators. Like, Shinhan Bank in South Korea is using Hedera to make cross-border payments fast and easy.
     
  2. Supply Chains and Knowing Where Stuff Comes From: Big names like Avery Dennison are using Hedera to keep tabs on products and make sure they're real. Its secure record-keeping helps show where things came from and lets you check up on them.
     
  3. Digital Tokens and IDs: You can use this stuff for anything from NFT spots (like LG Art Lab) to owning parts of buildings and setting up ID systems that play by the rules.
     
  4. Health and Keeping Data Safe: Hedera's system can securely keep track of medical records, test info, and where drugs are in the supply chain. Outfits like Safe Health Systems are already using it to keep things private and trustworthy.
     
  5. Green Stuff and Tracking Carbon: Stuff built on Hedera, like the Guardian 2.0 system, lets you track carbon offsets, so you can be transparent about climate stuff and stop fraud.
     
  6. Energy and Voting: Hedera helps with things like people trading energy directly, running small power grids, and setting up voting systems that are clear and open—making things better for the planet and for democracy.
     
  7. Business Tasks and Storing Files: From AdsDax fighting ad scams to using Hedera for keeping files safe and running company tasks, Hedera's getting used all over the place.
     
  8. Other Stuff People Are Doing: Pfizer and the UK's NHS used Hedera to watch how COVID-19 vaccines were being stored with sensors. Projects like Agryo are putting farmer-lender info online to make things clear. Cool new ideas include DOVU's tokenized carbon credits and Tune.fm's streaming setup.

What’s Coming Up for Hedera?

Hedera's getting bigger, especially with things like tokenizing assets, digital IDs, and green energy options. By open-sourcing with the Linux Foundation’s Hiero project, they’re getting more people to join in and invent stuff. Plus, they're always trying to make it faster, making it even better for companies.

Why do companies choose Hedera blockchain?

  • Super Quick Transactions: Hedera processes transactions super fast, typically in just 3–5 seconds. This speed lets businesses deal with tons of transactions without slowing things down. Everything stays smooth, even when it's busy.
  • Affordable, Stable Fees: Hedera's transaction fees are super cheap, like tiny fractions of a cent, no matter what’s going on with the market. Since costs are easy to predict, businesses can make solid budget plans. That's awesome for business growth without cost surprises.
  • Best Security Around: Hedera uses something called the asynchronous Byzantine Fault Tolerant (aBFT) consensus algorithm. This is one of the safest ways to keep data safe on networks. It locks out the bad guys, making it a secure pick for vital business apps.
  • Good for the Earth: Unlike older blockchains that use loads of power, Hedera uses almost none. The system cuts down on carbon use, which is a great fit for companies that value being green and hitting their ESG goals.
  • Well-Governed and Controlled​​​​​: Hedera is managed by well known companies like Google, IBM, and Boeing. This setup helps keep things transparent, fair, and trustworthy. The platform then meets tough requirements and standards.
  • Handles a Whole Lot​​​​​: Hedera can handle thousands of transactions each second without a problem. This ability to grow is perfect for companies doing business all over the world, supporting millions of users on one network.

Basically

Hedera Hashgraph is a pretty neat distributed ledger tech. It’s got really fast transactions, doesn't use much energy, has a solid group of big companies backing it, and lets Blockchain Developers use both EVM and native tools. No matter if you're building something for Web3, starting a big business system, or trying to be more eco-friendly, Hedera's a good platform that's ready for the future.
