What is Hedera?
Hedera is a proof-of-stake public distributed ledger which aims to use a combination of a “path to permissionless” (network nodes) and a “path to widespread coin distribution” (HBAR cryptocurrency) to keep the network secure, while working to achieve full decentralization.
Hedera Consensus Service
The Hedera Consensus Service offers applications direct access to the native speed, security, and fair ordering guarantees of the hashgraph consensus algorithm. Using this service, clients can submit messages to the Hedera public ledger for time-stamping and ordering. Clients can also encrypt the message contents, ensuring an application's ability to preserve their user's privacy and prevent the publishing of PII. Messages can include important actionable information in them, events such as for a money transfer settlement, user engagements in an advertising platform, tracking of provenance in a supply chain, and more. These ordered messages will flow out to mirror nodes or clients of mirror nodes for processing in the consensus order. By using Hedera Hashgraph for tamper-proof and verifiable logging of transactions, disparate participants and systems have a real-time view into application events.

The Hedera proof-of-stake public network, powered by hashgraph consensus, achieves the highest-grade of security possible (ABFT), with blazing-fast transaction speeds and incredibly low bandwidth consumption. By combining high-throughput, low fees, and finality in seconds, Hedera leads the way for the future of public ledgers.
Achieve fast, low-latency transactions with guaranteed finality in seconds, not minutes or hours. Hedera is an order of magnitude faster than blockchain alternatives.
The hashgraph data structure and consensus algorithm provides a new platform for distributed consensus. This introduction gives an overview of how hashgraph works, and some of its properties. The goal of a distributed consensus algorithm is to allow a community of users to come to an agreement on the order in which some of the users generated transactions, when no single member is trusted by everyone. In this way, it is a system for generating trust, when individuals do not already trust each other. Hashgraph achieves this in a fundamentally new way.
A blockchain is like a tree that is continuously pruned as it grows – this pruning is necessary to keep the branches of blocks from growing out of control and to ensure the ledger consists of just one chain of blocks. In hashgraph, rather than pruning new growth, such growth is woven back into the body of the ledger.
