Hedera vs Tezos

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.

Tezos is a self‑amending Proof‑of‑Stake Layer‑1 that supports on‑chain governance, letting token holders adopt protocol upgrades without hard forks. Its latest ‘Mumbai’ upgrade activated Smart Rollups, allowing scalable L2s written in Rust and Wasm to inherit Tezos security. Tezos processes ~1 million contract calls daily and is popular for compliant tokenisation of securities in Europe.
