An In-Depth Look At Hedera Hashgraph
I have been on the Decentralized Identification (DIDs) bandwagon for a while now. I am tired of storing my data in hundreds of vulnerable places, some I can’t even remember signing up for, until I get a letter informing me that my data was part of a data breach! It is annoying at best, financially destructive at worst. Web3 adoption will end this nightmare.
Today, my focus is on a unique platform that promises to secure your data without blockchain technology – Hedera Hashgraph. Web2 was a way to get people signed up and online at the speed of technology in 1995.
Web3 is Coming
Decentralized Identification is why.
The Web3 migration efforts using Hedera are being shepherded by some of the biggest names in technology, like Google, IBM, Dell, LG, Hitachi, and Service Now, among 33 others.
With this weight behind it, we should take notice.
Hedera Hashgraph is a Distributed Ledger Technology (DLT), but it is not another “Blockchain”. In this review, I will walk you through the difference between blockchains, as used by Bitcoin and Ethereum, and the Hedera Hashgraph.

★★★★★★★★★★ (10/10) based on performance, security, and innovation.
The Five Pillars of Effective Distributed Ledger Technology
What truly makes a Distributed Ledger Technology (DLT) valuable in today’s digital ecosystem:
- Security must be unassailable, ensuring transactions remain tamper-proof once verified.
- Scalability determines real-world viability—can the system handle millions of transactions without buckling under pressure?
- Energy efficiency has emerged as a non-negotiable as we face climate challenges; a DLT should secure assets without environmental devastation.
- Governance structure matters tremendously—who controls updates, fixes vulnerabilities, and steers development affects long-term stability and adoption.
- Practical implementation costs (both financial and technical) determine whether a system remains theoretical or becomes transformative.
These five pillars—security, scalability, sustainability, governance, and accessibility—create the framework we should use to evaluate any DLT that claims to power our Web3 future.
The Classic DLT Model – Bitcoin (2009) and Ethereum (2015)
How Blockchain Works:
- Structure: Data (e.g., transactions like “Alice sends 1 BTC to Bob”) is grouped into “blocks.” Each block is like a page in a ledger book, holding a batch of transactions.
- Blocks are linked in a chain—each one references the previous block’s unique cryptographic hash (a digital fingerprint), forming a chronological sequence.
- Consensus: To add a block, network nodes (computers) must agree it’s valid using a consensus mechanism:
- Bitcoin: Proof of Work (PoW)—Miners solve complex math puzzles, burning energy (885 kWh/transaction) to “win” the right to add a block. Takes ~10 minutes per block.
- Ethereum: Proof of Stake (PoS) since 2022—validators stake ETH to propose blocks, faster (~15 seconds) but still sequential.
- Once agreed, the block is added, and all nodes update their copy of the chain.
- Processing: Transactions are handled one block at a time. If a block holds 2,000 transactions and takes 10 minutes (Bitcoin), that’s ~3.33 transactions per second (TPS). Ethereum manages ~25 TPS pre-sharding—still slow for mass scale.
- Bottleneck: Only one block processes at a time; others wait in a queue (mempool).
- Strengths:
- Secure: It is essentially impossible to alter past blocks due to the hash chain.
- Proven: Bitcoin has run for 15+ years without a major hack.
- Weakness: Slow, energy-intensive (PoW), and costly (Ethereum gas fees spike).
- Visual: Imagine a single-file line of trucks (blocks) unloading goods (transactions) one by one at a warehouse. It’s orderly but sluggish.
The Hedera Hashgraph Model
Hedera Hashgraph, launched in 2018, ditches blocks entirely. It was created to address the limitations of traditional blockchain technologies. Designed to provide a faster, more secure, and scalable platform for decentralized applications and digital trust in a Web3 world.
Launched in 2018 by founders Dr. Leemon Baird and Mance Harmon, its origins stem from a vision to rethink Distributed Ledger Technology (DLT) beyond the constraints of blockchains like Bitcoin and Ethereum.
Here’s the Contrast:
- Structure: No blocks! Instead, transactions are recorded as individual events in a graph-like structure.
- Each event (e.g., “Alice pays Bob”) links to two prior events via hashes, forming a web of connections—not a chain.
- Think of it as a family tree, branching and weaving together, not a straight line.
- Consensus: Uses “gossip about gossip” and virtual voting:
- Gossip: Nodes share new transactions (gossip) with others randomly, attaching timestamps and hashes to prior events they’ve heard about. This spreads data fast.
- Virtual Voting: Nodes don’t vote directly. Instead, each calculates what the network would agree on based on the gossip history (who saw what, when). Asynchronous Byzantine Fault Tolerance (aBFT) ensures consensus even if some nodes fail or act maliciously—final in 3-5 seconds.
- No mining or staking wars—just math and communication.
- Processing: Transactions flow in parallel, not batched into blocks.
- Nodes process events as they hear them, weaving them into the hashgraph simultaneously. Hedera hits 10,000 TPS because it’s not waiting for a single “truck” to unload—many happen at once.
- Example: While Bitcoin processes one block every 10 minutes, Hedera could handle 193 million transactions (your VoterHub scale) in 5.36 hours.
- Strengths:
- Speed: 10,000 TPS vs. Bitcoin’s 3-7 or Ethereum’s 25—parallel beats sequential.
- Efficiency: 0.000003 kWh/transaction, carbon-negative vs. Bitcoin’s 885 kWh.
- Cost: Fixed $0.0001 fees (in HBAR), no gas spikes.
- Weakness: It is less battle-tested than Bitcoin (6 years vs. 15), and council governance isn’t fully permissionless.
- Visual: Picture a bustling network of couriers (nodes) shouting updates to each other across a city, instantly sorting deliveries (transactions) without waiting in line. It’s chaotic but lightning-fast.
