“Hedera’s unique approach combines high throughput with strong security measures to create a more stable and efficient environment for blockchain applications,” says a representative from COINOTAG.
Explore how Hedera Hashgraph is transforming DLT with its high-speed, low-cost solutions and unique governance, offering a viable alternative to traditional blockchains.
What is Hedera Hashgraph?
Hedera Hashgraph is a public distributed ledger platform and governing body designed for the real-world enterprise adoption of decentralized applications (DApps), digital payments, and asset tokenization.
➤ Hedera employs the hashgraph consensus algorithm, developed by Dr. Leemon Baird, which delivers high performance, robust security, and effective governance.
The platform is governed by a council of leading global enterprises, which it claims promotes decentralization and stability.
Hedera’s key features include:
- High throughput: It enables hundreds of thousands of transactions per second, ideal for large-scale applications.
- Security: Achieves asynchronous Byzantine Fault Tolerance (aBFT), offering a high standard of security resilient to DDoS attacks.
- Fairness: Transactions are ordered based on their arrival sequence, preventing manipulation and front-running.
- Stability: The network incorporates measures to prevent forking, maintaining its integrity.
- Governance: The decentralized model led by the Hedera Governing Council ensures inclusive decision-making.
How Hedera Hashgraph works
Hedera Hashgraph distinguishes itself from traditional blockchains through its unique consensus model. Instead of relying on proof-of-work (PoW) or proof-of-stake (PoS), it uses a hashgraph consensus algorithm that emphasizes speed, security, and fairness without necessitating energy-intensive mining.
This innovative approach allows for rapid and scalable transaction processing while preserving decentralized trust.
Hashgraph consensus
Hashgraph can be viewed as an evolution of blockchain consensus mechanisms.
While blockchains arrange transactions in sequential blocks verified by validators, Hashgraph operates with a graph of cryptographically linked events, allowing asynchronous transaction recording while achieving network consensus.
In this model, all nodes participate in consensus, which invites comprehensive network engagement.
➤ Hedera’s consensus mechanism leverages gossip-about-gossip and virtual voting to drive speed and operational efficiency.
Virtual voting and gossip protocol
The gossip-based protocol allows each node to randomly connect with others to exchange transaction and historical data, thereby propelling rapid consensus throughout the network.
This efficient dissemination of information enables nodes to swiftly agree on transaction ordering, eliminating the need for dedicated leaders. Additionally, gossip-about-gossip allows nodes to share cryptographic hashes, supporting a complete transaction history with minimal communication overhead.
For instance, when Peter completes a transaction with Tony, he shares it with Tony, who in turn shares it with Bruce, ensuring swift propagation across the network without heavy mining requirements.
The virtual voting mechanism strengthens this model by permitting nodes to infer votes based on shared histories, which lessens latency and escalates throughput.
Fair ordering and timestamping
Hedera enhances transparency by implementing median timestamping for transaction ordering.
Each transaction receives a consensus timestamp based on the median from the timestamps reported by two-thirds of nodes, preventing manipulative practices.
In summary:
➤ Fair timestamping: Calculated via the median of incoming timestamps.
➤ Consensus-based ordering: Transactions are processed according to their consensus timestamps.
➤ Immutability: Transactions are permanently recorded once consensus is achieved.
Security and Byzantine Fault Tolerance (aBFT)
Hedera’s aBFT mechanism guarantees security even in scenarios where some nodes act maliciously or fall silent.
This consensus structure ensures that confirmed transactions are non-reversible, achieving certainty absent from traditional blockchain systems.
Hedera’s design effectively minimizes single points of failure, offering defenses against common threats like DDoS attacks and Sybil attacks.
Fork prevention and network stability
Hedera’s architecture avoids the forking issues common in open-source blockchain environments by ensuring a cohesive network through governance and technical provisions.
The Hedera Governing Council enforces any network modifications carefully, maintaining a unified and immutable ledger that is particularly advantageous for sensitive applications.
