Layer 1 (L1) Governance, as exemplified by networks like Ethereum (via EIPs) and Cosmos (via on-chain proposals), excels at providing cryptoeconomic finality and shared security. A protocol's rules are enforced by the base layer's validators, creating a unified security budget. For example, Ethereum's ~$50B in staked ETH secures all applications simultaneously, making it the benchmark for high-value, immutable state. This model minimizes sovereignty but maximizes censorship resistance and liveness guarantees.
