sidechain

Polygon PoS is technically a sidechain that uses its own validators rather than Ethereum's security.从技术上讲，Polygon PoS 是一个侧链，它使用自己的验证者而不是以太坊的安全性。

Sidechains offer scalability but at the cost of security—they do not inherit the parent chain's consensus guarantees.侧链提供了可扩展性，但代价是安全性——它们不继承父链的共识保证。
