最近以太坊的 Layer 2 引起很大的討論
小弟大致上看了一下後還是似懂非懂想請教一下
layer2和側鏈好像都屬於一種擴展以太坊的方案
但差別是只有layer 2才是真正安全的?
layer 2是直接繼承以太坊的安全性的
意思是只要以太坊受算力保護還是安全的
你在layer 2上的資產就是安全的?
而側鏈可以想像成另一條區塊鏈
有自己的共識
所以側鏈的安全並非繼承自以太坊
而是靠自己
然後雖然現在 polygon 被看作是最先出頭的layer 2
但看到不少資料說 polygon 其實不是真正的layer 2 只是側鏈?
Arbitrum、Optimism 才是真正的layer 2
這種說法正確嗎?
