## Sidechain Consensus

Sidechain Consensus refers to the mechanism by which a secondary chain agrees on the order and validity of its transactions. Unlike the main chain, which often uses proof-of-work or proof-of-stake, sidechains can use more flexible and faster consensus algorithms.

These can be optimized for high-frequency trading and low latency, which is ideal for derivative platforms. However, the trade-off is that these chains must eventually anchor their state to the main chain to inherit its security.

The choice of consensus algorithm impacts the decentralization and security profile of the sidechain. It is a fundamental design decision that shapes the performance and trust assumptions of the entire scaling architecture.
