"Hashgraph is a consensus algorithm used to build and run shared worlds – fully distributed applications that harness the power of the cloud without servers. This algorithm was open sourced under Apache 2.0 license in 2022 to enable broader community participation. Now anyone can develop applications that rapidly achieve consensus, resulting in secure, stable, and sustainable transactions at a fraction of the cost of traditional server-based platforms, without any single point of failure."

"Hedera is the only public ledger – a highly secure and distributed database that everyone can read from and write to – that uses hashgraph consensus, a faster, more secure alternative to blockchain consensus mechanisms. The ledger consists of the platform, a network comprised of consensus and mirror nodes, as well as network services, a set of APIs that allow you to create accounts, mint tokens, write data to the ledger, call smart contracts, and other functions."

"From the team that founded and built out Hedera, Swirlds Labs now leads the development of the Hedera platform and network services, and will be building open source components that enable faster deployment of industry solutions. From the brain of Dr. Leemon Baird, the inventor of hashgraph, Swirlds Labs’ ‘moonshot’ projects will change the way humans and organizations have privacy, security, and trust in their shared worlds."

"A new system, the Swirlds hashgraph consensus algorithm, is proposed for replicated state machines with guaranteed Byzantine fault tolerance. It achieves fairness, in the sense that it is difficult for an attacker to manipulate which of two transactions will be chosen to be first in the consensus order. It has complete asynchrony, no leaders, no round robin, no proof-of-work, eventual consensus with probability one, and high speed in the absence of faults. It is based on a gossip protocol, in which the participants don’t just gossip about transactions. They gossip about gossip. They jointly build a hashgraph reflecting all of the gossip events. This allows Byzantine agreement to be achieved through virtual voting. Alice does not send Bob a vote over the Internet. Instead, Bob calculates what vote Alice would have sent, based on his knowledge of what Alice knows. This yields fair Byzantine agreement on a total order for all transactions, with very little communication overhead beyond the transactions themselves."
