What is hashgraph consensus?
The hashgraph consensus algorithm enables distributed consensus in an innovative, efficient way. Hashgraph is a distributed consensus algorithm and data structure that is fast, fair, and secure.
What is Hedera?
Hedera is a fully open source public distributed ledger that utilizes the fast, fair, and secure hashgraph consensus. Its network services include Solidity-based smart contracts, as well as native tokenization and consensus services used to build decentralized applications.
What is asynchronous Byzantine Fault Tolerance (ABFT)?
Asynchronous byzantine fault tolerance (ABFT) is a property of Byzantine fault tolerant consensus algorithms, which allow for honest nodes of a network to guarantee to agree on the timing and order of a set of transactions fairly and securely.
What is gossip about gossip?
Hashgraph utilizes the gossip protocol to send information between network nodes and come to consensus on transactions. Gossip about gossip is the history of how these events are related to each other, through their parent hashes, resulting in a directed acyclic graph (DAG) called a hashgraph.
What is the Hedera mirror network?
The Hedera Mirror Network is a parallel network dedicated to propagating the state and transaction history of the Hedera Main Network.
Open Source at Hedera
Hedera network services code and developer tools are all open source under an Apache 2.0 license. The hashgraph consensus algorithm will be open sourced under Apache 2.0 in 2022.
