Layer 1: Core IT, Operations & Foundation Market: Kaia: Merged Klaytn–Finschia EVM Layer‑1 for Developers
Kaia is an EVM-compatible Layer 1 blockchain formed in August 2024 by merging Klaytn (Kakao's chain) and Finschia (LINE's chain). Kaia uses BFT proof-of-stake consensus with ~1-second block times and immediate finality (no reorgs) and retains chain ID 8217. It exposes both the standard eth_* JSON-RPC namespace (recommended for Ethereum tooling) and the legacy klay_* namespace for Kaia-native features. A standout protocol feature is fee delegation, which lets a separate fee-payer account sponsor gas to enable gasless UX via Kaia-native transaction types built with the Kaia SDK. SwiftNodes provides a flat-rate Kaia RPC endpoint (HTTP + WebSocket) for developers to connect to the network.
New EVM Layer‑1 with immediate finality and messaging-app distribution potential is relevant to developers and consumer-focused blockchain apps, but it is a niche infrastructure announcement with limited direct impact on the broader AdTech/MarTech industry.
