Hedera Hashgraph is a public network that is designed to offer high-grade services for digital currencies, smart contracts, and file storage purposes. Being a third generation distributed ledger technology (DLT), it solves several problems inherent in its predecessors, the blockchain technology.
Hedera Hashgraph was developed by Leemon Baird and Mance Harmon in 2016. Rather than using blocks like blockchains, the Hashgraph uses a graph-like structure to capture data about transactions. This makes it more efficient and reliable, with the ability to process hundreds of thousands of transactions per second, making it an attractive option for businesses and organizations looking for high-speed, secure, and trustworthy solutions.
The technology behind Hedera Hashgraph, called the 'hashgraph consensus', claims to provide unprecedented speed, security, and fairness. Unlike Blockchain, which uses 'Proof-of-Work' (a time-consuming and expensive process) to validate and record transactions, Hedera Hashgraph stands out by adopting the 'Gossip about Gossip' and 'Virtual Voting' mechanism. It doesn't require the massive energy consumption, enhances security, and speeds up transactions.
One of the standout features of Hedera Hashgraph is that it is governed by the Hedera Governing Council, a group of renowned global enterprises across industries. These companies oversee changes to the software run by the nodes in the Hedera public network. Council members, including IBM, Google, LG, and more, assure network stability, guarantee continuous decentralization, and make crucial decisions for the future of the platform.
Hedera also has a native cryptocurrency, the HBAR, which plays a vital role in securing the network, accessing services on the platform, and incentivizing node participants for contributing to network functionality. The HBAR will be used to power decentralized applications, build peer-to-peer payment and micropayment business models, and protect the network from malicious actors.
In terms of security, Hedera is designed to be robust against attacks. It achieves consensus quickly because it doesn’t need to keep a record of the entire transaction history. Furthermore, the hashgraph algorithm uses asynchronous Byzantine fault tolerance (ABFT), making it resilient to Distributed Denial of Service (DDoS) attacks.
From an application standpoint, Hedera Hashgraph can be applied in various sectors. One key area is in maintaining public records such as property deeds and academic degrees. Additionally, it could also revolutionise industries like gaming, supply chain, and IoT devices by allowing faster, instant data synchronization.
In conclusion, Hedera Hashgraph offers unique capabilities that have the potential to revolutionize the way we transact, interact, and make decisions as a collective. If it can deliver on its promises, it could potentially outpace traditional blockchain technologies. However, as with any new technology, it will need time to mature, and its adoption will depend on its ability to convince organizations of its advantages and inspire the confidence of users and programmers. It remains an intriguing development in the world of digital technologies and one to watch in the future.
