关于共享安全性和独立安全性

It’s important to note that each shard in ETH2 will share the same security as every other shard. In order to break a single shard, you would have to break the entire system. This security model provides much better guarantees of safety than platforms like Cosmos, where every chain is responsible for its own security, resulting in a fragmented and easily attackable network. 

一篇关于 ETH2.0 的文章,ETH2.0 会使用和 Polkadot 一样的共享安全性。文章里说共享安全性相对 Cosmos 这种每条链分别负责自己安全的平台会提供更好的安全保障。这也印证了 Polkadot 的目标是取代 ETH,因为这两者在很多架构上太相似了。但是 Cosmos 的独立安全性也有它的优点。那就是链的主权性和自由性。
