Hedera vs Ink

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.

Ink is Kraken's Ethereum OP Stack Layer-2 built as a DeFi-focused member of the Optimism Superchain. It offers EVM compatibility, low fees and one-second blocks from launch, with sub-second blocks planned, so builders can deploy lending, DEX and yield applications close to Kraken's user base. No dedicated Ink token is mapped yet, so the blockchain is imported without an associated token.
