Hedera Hashgraph: Blockchain Alternative?

 Hedera Hashgraph: A Blockchain Alternative?

Hedera Hashgraph is not a blockchain—it's a distributed ledger technology (DLT) that uses a unique consensus algorithm called the Hashgraph consensus. Developed by Dr. Leemon Baird and governed by the Hedera Governing Council, Hedera aims to provide faster, fairer, and more energy-efficient alternatives to traditional blockchain platforms.


🧠 What Is Hashgraph?

Hashgraph is a graph-based distributed consensus algorithm that differs from blockchains in key ways:


No blocks


No miners


No chain


Instead, it uses a technique called gossip-about-gossip and virtual voting to achieve consensus quickly and fairly.


⚙️ Key Features of Hedera Hashgraph

Feature Description

Consensus Algorithm Hashgraph (Asynchronous Byzantine Fault Tolerant)

Transaction Speed ~10,000 TPS (for token transfers)

Finality Sub-5 seconds

Energy Efficiency Extremely low (much lower than PoW chains)

Governance 39-member Governing Council, including Google, IBM, LG, Boeing, etc.

Native Token HBAR


🔍 How Hashgraph Works (Simplified)

Gossip Protocol

Nodes randomly gossip about transactions to other nodes.


Gossip About Gossip

Nodes also share metadata about who they’ve talked to and when.


Virtual Voting

Because everyone has the same information, each node can deterministically calculate the outcome of a vote—without actually communicating.


Consensus Time

Each transaction gets a consensus timestamp, which determines the exact order of transactions—ensuring fairness and finality.


🌐 Use Cases of Hedera

Hedera is used in both enterprise and public dApp settings. Key use cases include:


Micropayments and streaming payments (low latency, low fee)


Tokenized assets and stablecoins (via Hedera Token Service)


Decentralized identity (DID)


Supply chain tracking


CBDCs and financial infrastructure


✅ Advantages Over Blockchains

Feature Hedera Traditional Blockchain

Architecture DAG (Directed Acyclic Graph) Chain of blocks

Speed Higher (10k+ TPS) Lower (Ethereum ~15 TPS)

Finality Instant, deterministic Probabilistic or delayed

Energy Use Minimal High (especially PoW)

Governance Transparent, corporate-led council Often pseudonymous or token-based


⚠️ Criticisms & Considerations

Governance Centralization: Some criticize the council model as too centralized, although the council is designed to be globally distributed and term-limited.


Not Permissionless (Yet): Full permissionless node operation is planned but currently limited.


Not a Blockchain: Developers used to blockchain architecture may find Hashgraph’s model unfamiliar.


🔑 Summary

Feature Description

Technology Type DAG-based distributed ledger (not blockchain)

Consensus Hashgraph (aBFT)

Native Token HBAR

TPS 10,000+ (token transfers)

Use Cases Finance, supply chain, identity, payments

Governance 39 global enterprises on the Governing Council


🧠 Final Thoughts

Hedera Hashgraph presents a compelling alternative to traditional blockchains—especially for applications that demand high throughput, low fees, and deterministic finality. Its enterprise-focused governance and innovative consensus model give it a unique position in the Web3 ecosystem, though it still faces challenges in decentralization and adoption.

Handling Frames and Iframes Using Playwright

Handling Frames and Iframes Using Playwright When automating modern web applications, you’ll often come across frames or iframes—HTML elements used to embed another HTML document within the current page. If you're using Playwright for browser automation, knowing how to handle frames properly is crucial for interacting with elements inside them. In this blog, we’ll walk through how to identify, access, and interact with frames and iframes using Playwright with code examples in JavaScript and Python. 🧾 What Are Frames and Iframes? <frame>: Rarely used now; part of the outdated <frameset> HTML structure. <iframe> (inline frame): Embeds another HTML page inside the current one. Common for third-party content like ads, maps, or payment gateways. 🎯 Why Frames Matter in Automation Elements inside an iframe are not part of the main DOM, so trying to interact with them directly will result in errors unless you switch the context to the frame. 🔍 Locating an Iframe in Pla...

Working with Tosca Parameters (Buffer, Dynamic Expressions)

🧪 Working with Tosca Parameters (Buffer, Dynamic Expressions) In Tricentis Tosca, parameters help you make your tests flexible, reusable, and data-driven. Two powerful types of parameters in Tosca are: Buffers Dynamic Expressions Let’s understand each one and how to use them effectively. 🟦 1. What is a Buffer in Tosca? A Buffer is a temporary in-memory storage used to store values during test execution. You can store a value in a buffer and then reuse it anywhere in your test case. 🔹 When to use: Save a value from one step and reuse it later Pass values between test steps or modules Dynamically build test data ✅ How to Create a Buffer In a Tosca TestStep, you use the syntax: text Copy Edit =>BufferName This saves a value to a buffer. Example: Capture an Order ID after placing an order: text Copy Edit ActionMode: Buffer Value: =>OrderID This stores the Order ID in a buffer named OrderID. ✅ How to Use a Buffer You can reuse the buffer value like this: text Copy Edit {B[OrderID]}...
