Data availability has been an exciting and new topic for discussion among the #CardanoCommunity recently
But it's also an abstract and complex topic
So here's a thread that simplifies "Data availability"(DA)
And how a DA-Layer would function on #Ethereum 2.0

Data availability is the guarantee that the block proposer published all transaction data for a block
And that the transaction data is available to other network participants
Why is it important?
For this, one must understand how trustlessness work in public blockchains

• Block:
Each block has two major parts:
• The block header:
This contains general information (metadata) about the block
Such as the timestamp, block hash, block number, etc.
• The block body:
This contains the actual transactions processed as part of the block

L1大一统，L2百花齐放，这应该是个基本判断，跟价格，手续费，新入场用户喜好这些一点关系都没有

看看WEB2: 美国，欧洲，澳大利亚为什么没有微信支付/支付宝这么方便&便宜的业务，paypal等为啥手续费这么高？因为中国国内有一个政府行为推动的L1: 银联。
一旦L1割裂，千辛万苦的地推，烧钱砸出来的Visa/Master就有极高的门槛和网络效应，成本长期就转嫁到消费者头上。而且对Visa/Master是回报递增的

至于ETH 手续费虽高，但是随着升级和L2，手续费是递减的。
只要没有范式更新级别的新需求被发现，其它靠手续费低/速度快的选手，在生态复杂度面前没有任何机会。
因为任何业务要在割裂的L1上发展，就和WEB2上没有银联支付的地方发展在线业务一样，各种摩擦高到哭。
