Scalability: The battle between Layer‑1 speed, Layer‑2 roll‑ups, and side‑chains. L1s like Solana and Avalanche offer high throughput but at the cost of centralisation. Roll‑ups keep base‑layer security, adding cost per tx but scaling by orders of magnitude. Side‑chains give speed and custom rules, yet lose the security anchor.
