Shared Sequencers Explained: Why Rollups Care and How Rewards Flow

Nodes, L1/L2, Rollups /

Shared Sequencers Explained: Why Rollups Care and How Rewards Flow Rollups promised cheap, fast transactions secured by a base chain, but most still rely on a single, often centralized sequencer to order transactions. Shared sequencers are the next step: a neutral, decentralized ordering layer multiple rollups can plug into. They aim to improve liveness, censorship […]

Sidechains and State Channels

Nodes, L1/L2, Rollups /

Sidechains & State Channels Two non-rollup scaling approaches: separate chains with their own security, and off-chain micro-transactions with on-chain settlement. TL;DR: Sidechains: Independent consensus + bridge to L1. Cheaper, but inherit sidechain security (not L1). State channels: Lock funds on L1, exchange signed updates off-chain, settle final state on-chain. Great for rapid, repeated interactions. In
