Hedera vs Stellar

Hedera Hashgraph uses a gossip‑about‑gossip DAG protocol that achieves asynchronous Byzantine fault tolerance and finality in 3‑5 seconds. Governing Council members like Google and IBM run permissioned nodes, and the Hedera Token Service allows issuance without smart‑contract coding. The 2024 ‘Smart Contract 2.0’ release introduced Solidity bytecode support via Hyperledger Besu integration.

Stellar is a payments‑focused blockchain that uses the Stellar Consensus Protocol (SCP), a federated Byzantine agreement where each node chooses its own quorum slices. Anchors issue fiat‑backed tokens, and Stellar’s built‑in DEX offers path payments that can hop through multiple assets in a single transaction. The 2023 Soroban upgrade added WebAssembly smart contracts, enabling on‑chain AMMs, lending and other DeFi primitives.
