The network is governed by The Hedera Council, which includes leading global organizations from various sectors, ensuring decentralization and stability.

Understanding Hedera's Technology

Hedera's technology is a groundbreaking innovation in the field of distributed ledger technologies (DLT). Central to this is the Hashgraph consensus algorithm, which sets Hedera apart from traditional blockchain systems. This algorithm is designed to provide high performance, security and fairness.

Hashgraph Consensus

The Hashgraph consensus algorithm is the core of Hedera's technology. Unlike traditional blockchains that rely on proof-of-work (PoW) or proof-of-stake (PoS) mechanisms, Hashgraph uses a process called gossip-about-gossip combined with virtual voting. This approach ensures information about transactions spreads rapidly through the network, similar to how news travels across social media platforms. This method allows Hedera to achieve consensus quickly and fairly, enabling the network to process thousands of transactions per second with finality in just a few seconds.

Smart Contracts

Hedera supports smart contracts, which are self-executing contracts with the terms of the agreement directly written into code. These contracts can automate complex processes and transactions, reducing the need for intermediaries. Hedera's smart contracts are designed to be more predictable and less expensive compared to those on other blockchain platforms, making them highly attractive for enterprise use.

Hedera Consensus Service (HCS)

The Hedera Consensus Service (HCS) offers a way for applications to achieve decentralized trust by providing a decentralized ordering service for application messages. It acts as a trust layer for any application needing verifiable timestamps and ordering of events. This service is particularly useful for applications requiring audit logs, supply chain visibility, and more.

Hedera Token Service (HTS)

The Hedera Token Service (HTS) allows users to create and manage native tokens on the Hedera network. This service supports the issuance of both fungible and non-fungible tokens (NFTs) with configurable compliance features. HTS provides a flexible and robust framework for token management.

Security and Fairness

Hedera’s architecture ensures a high degree of security and fairness. The Hashgraph consensus algorithm guarantees that no single node can manipulate the transaction order, and all nodes participate equally in the consensus process. Furthermore, Hedera's asynchronous Byzantine Fault Tolerance (aBFT) ensures that the network remains secure even in the presence of malicious actors.

Hedera in the Blockchain Ecosystem

Hedera Hashgraph boasts several unique properties that set it apart in the blockchain ecosystem.

At the heart of its innovation is the Hashgraph consensus algorithm, which ensures fast, secure, and fair transaction processing. This technology enables Hedera to handle over 10,000 transactions per second, a significant improvement compared to many blockchain competitors like Bitcoin and Ethereum.

Hedera’s Hashgraph technology employs gossip-about-gossip and virtual voting mechanisms, resulting in rapid and efficient consensus. This method minimizes communication overhead and reduces the time to finality, making Hedera significantly faster and more scalable than traditional blockchain systems. For instance, while Ethereum 2.0 aims to improve scalability, it still cannot match the transaction speed and finality offered by Hedera.

Security and Fairness

Security is a paramount concern in any distributed ledger technology. Hedera provides asynchronous Byzantine Fault Tolerance (aBFT), ensuring that the network remains secure even in the presence of malicious actors.
