Scaling blockchain is a balancing act. Layer‑1 solutions like sharding boost raw capacity but can dilute decentralization. Layer‑2 rollups—Optimistic and ZK—off‑chain compute and batch—trade speed for trust assumptions. Sidechains give speed but risk centralization. Each path offers different trade‑offs between speed, cost, and security.

Decentralized insurance flips the old model on its head. Instead of banks underwriting risk, a community of token holders pools capital and uses smart contracts to automatically trigger payouts when predefined parameters are met. This removes intermediaries, cuts costs, and opens coverage to underserved markets. As protocols mature, expect more transparency, lower premiums, and truly global risk sharing.
