To understand Layer 2, start with this article

Since the second half of 2020, Bitcoin has been out of the loop, and Ethereum has become one of the biggest topics in the circle.

Ethereum 2.0 creation block officially opened; The long-debated EIP1559 proposal was added to the hard fork upgrade in July 2021, provoking strong opposition from miners; The price of Ethereum hit an all-time high, the DEFI market was hot, and Gas bills went up. All of this has also led to the expectation of Ethereum's Layer2 expansion scheme, which has begun to pay attention to blossom.

In order to help readers better understand Layer2's ecology and current situation, Rulse Blockbeats has sorted out the following articles:

introduction

Learn about Ethereum Layer2 Capacity Expansion in a Minute

What's the Layer2 expansion going on? What is the difference between projects such as Optimism, XDAI, OMG and Loopring? We'll answer those questions next.    

Technological development of the Layer 2 ecology of "a hundred flowers bloom"

How is the latest Layer 2 development going? What are the solutions? What will be the impact on Ethereum itself when Layer 2 enters the application?    

Ethereum Extensibility Solution Rollup

Rollup is very popular in the Ethereum community and will be a key scalability solution for Ethereum for the foreseeable future. But what exactly is the technology, what can you expect from it, and how will you use it? Ethereum founder V God himself wrote this article to try to answer some of these key questions.

Some thoughts on Layer2

What will the eagerly awaited Layer2 bring to the NFT space?

Although there are many limitations, Ethereum network is still the most ecological and perfect blockchain underlying platform in the blockchain world, and it is still the first choice for projects that want to carry blockchain technology. What is the development of NFT tracks for the Ethereum network, and how does the highly anticipated Layer2 solution enable NFT tracks?    

Why are there so many Layer2 solutions but nobody uses them?

As can be seen from the above popular science article, Ethereum's Layer 2 projects are already very rich, but Ethereum is still blocked. Why are Layer 2 applications rarely used?
