Governance and Development

Hedera is owned and managed by a governing council of global companies and entities, including Google, Boeing, IBM, and several others. The council has played a significant role in the development and decentralization of the network, including the transition of the hashgraph consensus algorithm to open source.

Technical Details

Hedera Hashgraph uses a "gossip about gossip" protocol to create directed acyclic graphs that time-sequence transactions. Each "gossip" message contains one or more transactions plus a timestamp, a digital signature, and cryptographic hashes of two earlier events. This makes Hashgraph form an asynchronous Byzantine Fault-Tolerant (aBFT) consensus algorithm. The network also employs a variant of Proof of Stake for consensus, which increases efficiency by reducing message-passing.

Storage and History

Hedera Mainnet nodes prioritize consensus and state persistence. The hashgraph, which contains all transactions that change the state, is constantly pruned after transactions are assigned a place in consensus order. Mirror nodes, on the other hand, can store transaction history, allowing for the retrieval of historical transactions and providing a way to store and query historical data from the public ledger while minimizing the use of Hedera network resources.

How Hedera Hashgraph works

Hedera Hashgraph (HBAR) is a decentralized, public ledger technology that uses a unique consensus algorithm called hashgraph. Here's how it works:

Hashgraph Consensus

Hashgraph is a patented algorithm that allows nodes on the network to communicate and agree on the order and validity of transactions. Unlike traditional blockchain consensus mechanisms, hashgraph does not rely on a single miner or validator to choose the next block. Instead, the entire network of nodes comes to a collective agreement on which transactions to add to the ledger.

The consensus process involves two key steps:

  1. Gossip-about-Gossip Protocol: Nodes on the network constantly share information with each other, creating a web of interconnected nodes. This gossip protocol ensures that each node has a comprehensive view of the network and all transactions.
  2. Virtual Voting: Nodes use the information gathered through gossip to vote on the validity and order of transactions. This virtual voting process ensures that the network reaches a consensus on the state of the ledger.
Transaction Processing

Here's how a transaction is processed on the Hedera network:

  1. Client Creates Transaction: A client creates a transaction, which is cryptographically signed to ensure authenticity.
  2. Node Processing: The transaction is submitted to any node on the network, which verifies the transaction and checks if the paying account has sufficient balance to cover the fees.
  3. Consensus: If the transaction is valid, the node adds it to an event and gossips that event to other nodes. The network quickly reaches consensus on the transaction through the gossip-about-gossip protocol and virtual voting.
  4. Immutable Ledger: Once consensus is reached, the transaction is added to the public ledger, which is stored on each node. The ledger is immutable, meaning that once a transaction is confirmed, it cannot be altered or deleted.
HBAR Token

HBAR is the native cryptocurrency of the Hedera network. It serves two primary purposes:

  1. Transaction Fees: HBAR is used to pay for transaction fees on the network. The cost per transaction is extremely low, around $0.0001 USD, making micropayments practical.
  2. Network Security: HBAR is used for staking, which helps secure the network. Nodes on the network stake HBAR to participate in the consensus process and earn rewards. This proof-of-stake mechanism ensures that the network is secure and resistant to malicious attacks.
Network Architecture

The Hedera network consists of two types of nodes:

  1. Consensus Nodes: These nodes are responsible for reaching consensus on transactions and maintaining the public ledger. They are currently permissioned but will be permissionless in the future.
  2. Mirror Nodes: These nodes offer developers a flexible and cost-effective way to store and query historical data for analytics and explorers.
Key Features

Hedera Hashgraph offers several key features that make it attractive for decentralized applications:

  1. High Throughput: The network can process over 10,000 transactions per second, making it much faster than traditional blockchain networks.
  2. Low Latency: Transactions achieve finality within three to five seconds, ensuring fast and secure settlements.
  3. Security: The hashgraph consensus algorithm provides high security and resistance to malicious attacks.
  4. Scalability: The network is designed to be highly scalable, making it suitable for large-scale decentralized applications.

Overall, Hedera Hashgraph offers a fast, secure, and scalable platform for building decentralized applications. Its unique consensus algorithm and native HBAR token make it an attractive option for developers and users alike.
