XDC Network (formerly known as XinFin Network) is a hybrid (public / private) blockchain platform that combines the transparency of public blockchains with the speed and security of private networks. With the help of blockchain technology and state-of-the-art infrastructure, the project intends to provide streamlined financial services to its users.

The protocol’s open-source software uses a delegated-Proof-of-Stake (XDPoS) consensus mechanism, which facilitates fast transactions, interoperability, and cybersecurity. The network can process 2000 transactions per second (TPS), and thanks to interoperable smart contracts and Ethereum Virtual Machine (EVM) compatibility, users can more easily scale their projects.

Hedera is the most used, sustainable, enterprise-grade public network for the decentralized economy that allows individuals and businesses to create powerful decentralized applications (DApps).

It is designed to be a fairer, more efficient system that eliminates some of the limitations that older blockchain-based platforms face — such as slow performance and instability.

It was funded through an initial coin offering (ICO) in August 2018 and first launched open access to its mainnet just over a year later in September 2019. As part of the ICO, investors were able to purchase the platform’s native utility token (HBAR) at the lowest possible pricing.

The HBAR token has a dual role within the Hedera public network.

First and foremost, HBAR the fuel that powers Hedera services, such as smart contracts, file storage and regular transactions. Second, it's used to help secure the network, since HBAR users can stake their tokens to assist with maintaining the integrity of the platform.

Hedera (HBAR) is the native cryptocurrency of Hedera Hashgraph, a platform that is positioned as an alternative to traditional blockchain technology and aims to excel in speed, efficiency and security.

Older blockchains tend to use a consensus mechanism like proof-of-work (PoW) to validate transactions, while younger blockchains opted for proof-of-stake (PoS). The Hedera Hashgraph system has a structure that was created from scratch particularly for the project. Hedera is based on a PoS model that is believed to increase the efficiency of transaction verification in the network, provide a high level of security, and protect the network from hacker attacks. Its ecosystem has the underlying hashgraph consensus algorithm and the global enterprise governing body.

Hedera Hashgraph is a distributed ledger technology (DLT). According to the project website, Hedera differs from other blockchains because it uses a new consensus algorithm called hashgraph. It intends to process and execute transactions faster, eliminate delays, and smooth out the TPS (transactions per second) indicator. Hashgraph is claimed to be an upgrade in transaction speed, cost, and scalability.

Core network services by Hedera:

Consensus Service (HCS). With HCS, clients send messages to the network to negotiate consensus timestamping and order. In this case, the state is stored offline, and users can define privacy and access control.

Hedera Token Service (HTS). Thanks to HTS, token creation and management are available to customers. It supports built-in tokenization.

The goal of Hedera’s hashgraph is to increase the speed of transactions. Moreover, the network is also focused on high-volume operations: micropayments, data integrity and tokenization.

Like the EVM, the Hedera network maintains a virtual machine that writes smart contracts in the Solidity programming language. On top of that, Hedera offers a set of built-in KYC and AML checks.

From a technical point of view, Hedera is a form of distributed ledger technology. It is a hashgraph, or consensus algorithm, where users agree on the order in which transactions should be performed. However, Hedera is not exactly a blockchain. It has its own distinctiveness and works differently. With hashgraph, all transaction branches are merged, no block equivalent is thrown away, and each is used to reach consensus.

One of the most noticeable features of the network is the Gossip-about-Gossip protocol. According to Dr. Leemon Baird, Hedera's inventor, within the system nodes randomly transmit data about themselves to other nodes via hashgraph using the Gossip protocol. Soon, all nodes in a cluster become familiar with each other. Then a certain data structure is formed. It consists of a payload of transactions, a timestamp, a digital signature, and hashes to the previous structures.

HBAR is Hedera's native token that powers applications on the Hedera network. HBAR is utilized to pay for network services, transaction fees, in-app payments and micropayments. Developers can pay network fees with HBAR tokens, namely: work with smart contracts, file storage and currency exchange. HBAR is used to incentivize and pay network nodes.

Hedera Hashgraph has a decentralized governance system that is set apart. All critical decisions about pricing policy, software updates, and wealth management are made by the Governing Council.
