Hedera vs Katana

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.

Katana is a DeFi Layer-1 chain incubated by Polygon Labs and GSR, designed to maximize on-chain liquidity and real yield. Its Vaultbridge system redeploys bridged assets like ETH and USDC into yield strategies on Ethereum, while Chain-owned Liquidity (CoL) channels 100% of sequencer fees into deep, protocol-controlled liquidity pools. Katana’s native AUSD stablecoin, backed by US Treasuries, powers lending markets and DEX liquidity with off-chain yield incentives.
