Exploring the Hedera Ecosystem

In the previous article on Hedera, we explored the basics of Hedera Hashgraph and the network around Hedera. We also learnt about the 'Gossip about Gossip' and 'Virtual Voting'. In this article, we will learn more about the ecosystem that empowers Hedera.

Headera Governing Council

Hedera Governing Council is a decentralized governing body that oversees the direction and governance of the Hedera network. The council is made up of 39 leading global organizations from various industries, including finance, technology, and telecommunications. The council members are responsible for ensuring the stability and security of the network, as well as making decisions about its future development.

Hedera Hashgraph mitigates decentralization concerns through a clear division of governance and consensus. This governance structure ensures that no single company, a select few developers, or node operators hold excessive sway or dominance over the network. Council members are subject to a maximum term limit of three years, with the option for up to two consecutive terms, each possessing an equal vote in shaping network and platform decisions. Swirlds, the creator of Hashgraph, has a permanent seat and equal vote.

The Purpose of the Council

The primary purpose of the Hedera Governing Council is to ensure that Hedera Hashgraph remains decentralized, stable, and secure. It achieves this by representing a diverse range of stakeholders and interests, preventing any single entity from having undue control over the network. Here are some key responsibilities and roles of the council:

Consensus Decisions: Council members participate in consensus decisions regarding network upgrades, policies, and key changes, making sure that these decisions reflect a broad consensus among various stakeholders.
Network Stability: They work collectively to maintain the stability, security, and performance of the Hedera network. This includes addressing any potential threats or vulnerabilities promptly.
Access Control: The council has a say in onboarding new members, ensuring that only reputable organizations with a vested interest in the network's success can join.
Legal and Regulatory Compliance: Council members assist in navigating legal and regulatory challenges, contributing to the platform's global compliance efforts.

Consensus and Mirror Nodes: The Backbone of Hedera Hashgraph

At the heart of Hedera Hashgraph's innovative distributed ledger technology (DLT) are two crucial components: the Consensus Mechanism and Mirror Nodes. These elements work in tandem to ensure the security, transparency, and reliability of the network.

Consensus Mechanism in Hedera Hashgraph

Hedera Hashgraph employs a unique consensus mechanism known as Asynchronous Byzantine Fault Tolerance (ABFT). This mechanism is designed to achieve high levels of security and efficiency. Here's how it works:

Gossip Protocol: Hedera Hashgraph nodes communicate with each other using a Gossip Protocol. In this process, nodes share information about transactions and events they have witnessed.
Eventual Consistency: Over time, nodes collectively build a directed acyclic graph (DAG) structure known as the Hashgraph. This DAG contains all transactions and their consensus timestamps.
ABFT Consensus: The ABFT consensus algorithm ensures that all nodes eventually agree on the order and validity of transactions without the need for resource-intensive proof-of-work (PoW) or proof-of-stake (PoS) mechanisms. This results in high throughput and low latency.
Timestamping: Hedera Hashgraph uses a system of timestamps to order transactions accurately. This mechanism prevents issues like double-spending and ensures the integrity of the ledger.
Fairness: The consensus mechanism promotes fairness by allowing nodes to take turns proposing and voting on transactions. No single node or group of nodes has undue control over the network
