Hedera vs ICP

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.

The Internet Computer (ICP) is a Layer‑1 that runs WebAssembly ‘canisters’ directly on chain, with sub‑second query calls and 2‑second update finality. Boundary nodes translate HTTP requests into signed chain queries, enabling dApps to serve web front‑ends without traditional servers. ICP’s reverse GAS model bills cycles in stable dollar terms, shielding developers from token volatility.
