An article reveals the evolution history of Layer 1 to Layer 3
secondary title
Evolution history from Layer 1When we talk about the blockchain, most of the words that come to mind: decentralization, highly decentralized, free operation and other keywords. When technology developers enjoy the dividends of the world on the chain, and users enjoy the functions and services on the chain, they may not have thought about the behind-the-scenes heroes who support all these operations——
Layer, the role played by the role played.
Layer, the Web bomb layer component, serves as a facility to realize the rich and convenient operation experience of the blockchain, and supports the performance and performance of operations on the chain.Well-known public chains such as Ethereum are built on the Layer 1 network, and the developed Layer 2 is also a popular narrative in recent years, but what are the advantages of the recently quietly emerging Layer 3?
This article will focus on Layer 3, and analyze how an evolutionary history from Layer 1 to Layer 2 to Layer 3 allows us to understand the necessity and practical significance of the birth of Layer 3.The forerunner of Layer 1 is a group of blockchain smart contract platforms represented by Ethereum. They compete with Ethereum with a higher degree of decentralization and higher transaction throughput, forming the "vanguard" of the Layer 1 camp. ". But without the infrastructure of Ethereum, the development of these public chains is difficult,
Therefore, many Layer 1s have adopted an "EVM compatible" strategy in order to complement the shortcomings of Ethereum and develop their own advantages.However, the rapid rise of Layer 1 has brought challenges and pressures to platform operations. The limited function of the Ethereum public chain makes it unable to bear the increasing amount of execution and calculation brought about by the rapid development of the ecology.。
In order to complete the transaction in the congested environment of the public chain, you have to pay high transaction coststhen,Layer 2 was born under the banner of fee reduction and capacity expansion
, the basic optimization logic of Layer 2 is to strip and layer the functions of the public chain, leave the consensus mechanism for providing security in Layer 1, delegate the calculation and execution to Layer 2, and promote the public chain to become the settlement layer of Layer 2. It is easier to implement and operate than mechanisms such as cross-chain and sharding. The popularization of Layer 2 applications and the significant reduction in transaction costs can be said to be a very successful industry change.On the premise of retaining the decentralized model, Layer 2 maximizes operational efficiency, but it is still insufficient in highly customized application scenarios.Since the blockchain can be layered, why not provide an independent layer for services?Wouldn't it be more personalized and easier to operate? ——
This was the initial inspiration for Layer 3.Layer 3 is nested on Layer 1 just like Layer 2, and it also has a nested and recursive relationship with Layer 2. The multiplicative effect proved by recursion,Achieve powerful scalabilityBy customizing the data model, the technical turnover rate and functional operation efficiency of the blockchain are accelerated.

The Necessity of the Birth of Layer 3
The necessity of Layer 3 lies in the selection of application scenarios that may actually be encountered. We can discuss such a situation:
What should I do if I send a DApp that can inherit the users and security of Ethereum, but I don’t want to just make a contract?
If choosing Cosmos, Polkadot or Alt-L 1 is excluded, only Rollups can be selected. But the cost of developing an L 2 Rollup is extremely high, how to solve this?
——Use L 3 SDK to develop an application-specific Rollup, namely Layer 3. In short, as analyzed above, Layer 2 is suitable for solving the problem of cost reduction and expansion, while Layer 3 is suitable for applications that require specific scenarios.
Recently, Vitalik, founder of Ethereum, talked about the practical application of Layer 3 and also concluded: "L 2 is used for expansion, and L 3 is used for customizable expansion. This customization accurately matches the special scenarios used by users and the preferences of developers. At the same time, L 3 has the feature of weak trust extension, leaving data availability to a trusted third party or committee to further protect user privacy and use security.”Further,。
If Layer 3 can achieve large-scale application, then privacy computing can be applied to any transaction anytime, anywhereWe all know that the data in the blockchain is encrypted to achieve privacy calculations between data through zero-knowledge proofs, smart contracts, etc., but this requirement cannot be supported by the current Layer 2 infrastructure. If the privacy computing function is successfully placed on Layer 3,。
With its strong scalability, it may be able to make privacy-preserving transactions on Layer 2 possibleIt would be a good choice to translate the combined operations between layers and the same layer to Layer 3, and it would be easier to manipulate and implement。

Looking ahead to Layer 3: A promising role in the Web 3 era
It can be seen that in the evolution history from Layer 1 to Layer 2 to Layer 3, the demand for continuous improvement in technology performance and enhanced experience has prompted Layer to continuously iterate and upgrade to an advanced version. And the process of these upgrades has revolutionized our cognition and views on the blockchain like lightning, so will Layer 3 be just a flash in the pan?
At present, the biggest foothold supporting the survival and development of Layer 3 lies in its ability to provide customized application services for specific scenarios. Layer 3 may open up a new space for Ethereum or blockchain, just like Rollup.The unique advantages of Layer 3 in application scenario services have greatly improved the application-level dilemma that the blockchain industry has long been difficult to break through.High computing volume, large-capacity load capacity, and customization are the obvious technical dividends brought by Layer 3 mature solutions, and they also urge batch after batch of blockchain applications for the Web 3 era to speed up the research and development progress.
For example, on-chain games may become the first batch of projects to deploy Layer 3.However, while seeing the stable and positive development of Layer 3, we also need to be vigilant against the current situation.The risk that the content of many Layer 3 services is inconsistent with user needs
, if these projects that deviate from user needs and specific scene goals are not optimized or improved, then Layer 3 will also become an invisible killer that wastes market resources and development space.For the blockchain industry, the layered model is an excellent solution to expansion.Layer 3 is just a fresh startThey are also expected to become an important part of the underlying logic of technological development in the Web 3 era。
