Hedera Hashgraph: Proof-of-Stake Consensus Without Blockchain

Hedera Hashgraph operates a public distributed ledger that does not rely on a blockchain. The network implements a directed acyclic graph (DAG) data structure combined with the Hashgraph consensus algorithm, a combination that distinguishes it from conventional blockchain architectures. This design delivers ~10,000 transactions per second (TPS) on the mainnet with 3–5 second absolute finality, compared to Ethereum’s ~15–30 TPS and ~13-minute ...
