• Reasons for choosing ZK-Rollup technology: Easily achieve the goal of licensing fairness and decentralization
• The powerful expansion capability and exit mechanism of ZK-Rollup technology is worthy of becoming the darling of the encryption world
• The Starknet Chinese community is attracting more developers to understand ZK through science information and educational activities
• How can developers grasp the ZK technology dividend? Learn technical documents, try to write code, and play the composability function on the chain

**Why choose ZK-Rollup? **Security, Fairness and Decentralization

Developers who are familiar with zero-knowledge proofs should know that the biggest advantage of ZK technology lies in security and privacy. In addition, both ZK era and Starknet natively support the account abstraction function, bringing a new experience to Web3 users. "We can expect that native support for account abstraction on both ZK era and Starknet is the only way for Web3 user volume to reach a higher level", Aaron said confidently. Using account abstraction, we can resolve the dilemma of high fees and long cycles in the traditional transaction process, and can also rely on ZK technology to enhance the privacy and security of the account to achieve licensing fairness and The goal of decentralization is a positive sign for user experience. "Blockchain and smart contracts themselves implement account abstraction at the bottom layer based on the principles of fairness and transparency. Whoever can develop an excellent wallet application faster can gain more advantages in the user market" .

However, while ZK-Rollup technology gives developers new opportunities, it is also full of challenges. "Many challenges in ZK technology itself come from the immaturity of the technology itself, such as the immaturity of the code that leads to false evidence," Mr. Icer summarized. Specifically, the first challenge is contract limitation, only very few specified information in the transfer records summarized by users are aggregated; the second challenge is support for complex logic, currently supports ZK EVM's technical attempts and performance improvement are still not ideal, "Facing the impossible triangle of the blockchain - security, scalability, decentralization, ZK-Rollup inherits the security of the main chain, but But it does not fully guarantee decentralization”; the third challenge is comprehensive risk, many platforms like ZK-Rollup support have exposed technical defects in contract upgrades, exit mechanisms, etc., which is worthy of vigilance . Facing the long-term development of the future, when ZK-Rollup technology is applied to the platform construction and project development process, it still requires top developers to maintain the awareness of "seeking advantages and avoiding disadvantages" in order to truly maximize strengths and avoid weaknesses.

ZK-Rollup technology and other expansion solutions** realize the advantages of "complementary"**

Technology and Ecology take advantage of each

Just as the development of ZK-Rollup technology is gradually flourishing, the relationship between ZK-Rollup and Ethereum and other Layer1 blockchain expansion solutions has begun to be discussed by developers. Many developers believe that there is a competitive relationship between them, which is not conducive to subsequent collaborative development. In this regard, Mr. Leo objected, he believes that this competitive relationship can also be regarded as a "complementary" relationship, both ecology and technology have their own strengths, "For example, Starknet helps Ethereum Fang uses ZK technology or solutions to better achieve expansion and improve operating performance.

Encourage developers to continue exploring

In addition, Ethereum’s infrastructure can have more potential for innovative exploration, such as the development of Layer2 applications, then this can also promote the development of the future market.” In the face of such a seemingly competitive technological ecology , **Developers' continuous exploration on different Layer2 or public chains is also a kind of "complementary" **, we should strive to give full play to our technological advantages in order to stand out in the market competition.

Build technical cooperation scheme

Even though the competition in the technology market is brutal, developers who choose ZK-Rollup technology are not on the wrong path. At present, ZK-Rollup technology has become the "sweet pastry" in the encryption world. The most important reason is that it improves scalability and has strong expansion capabilities without compromising the security of the main chain* *. In addition, ZK-Rollup has sufficient security guarantees. In the event of failure or shutdown, as long as there is a complete exit mechanism, users may withdraw their funds. With its flexible technical processing capabilities, ZK-Rollup will also explore a set of unique collaborative development solutions to achieve "complementary" development with more technical systems.

ZK-Rollup Application Forerunner ——Starknet's innovative experiment

In order to better move towards the encrypted world, Starknet has achieved outstanding results using ZK technology. Different from the previous ZK technology, Starknet uses ZK VM, **"****Although part of the operating efficiency is sacrificed, it can improve ZK performance, reduce the cost of use, and fully meet the expansion requirements", Mr. Leo pointed out. In addition, Starknet's custom developer language - Cairo, is used to support the abstraction of native accounts, and is committed to creating a convenient and easy-to-use contract wallet.

Starknet can achieve faster and more complex calculations on the chain, meeting the development needs of full-chain games. Many potential full-chain games and derivative games have been developed on Starknet. At the same time, Starknet also promotes dynamic NFT to settle in the full-chain game projects to realize various game ideas.

The developed Starknet Chinese community is also absorbing more Web3 developers to join the technology ecology. Teacher Leo introduced: "At present, the Starknet Chinese community is mainly doing two things, one is technical science popularization, doing daily information updates around the Twitter platform, and translating technical science content; the second is developer education, Help developers developing in the Crypto field to enter the Starknet ecosystem smoothly. In the future, Starknet will also hold educational training and hackathon competitions from time to time.” I believe that Starknet, which brings together more developers, will also develop amazing products.

**Grasp the investment opportunities of ZK technology, **Developers still need to improve their technical strength

As venture capitalists, Mr. Yuxing and Mr. Leek also saw investment opportunities behind the ZK-Rollup technology. “I am very concerned about the technological innovation of ZK-Rollup itself. For example, full-chain games are the industry direction worth investing in under the ZK-Rollup technology system; in addition, the combination of artificial intelligence technologies such as ZKML and ZK is also a potential game for future development. Dao,” said Teacher Yuxing. Compared with the specific investment track, Teacher Leek suggested that everyone look at ZK-Rollup technology from a more macro perspective. He pointed out that we need to solve the development problems faced by ZK-Rollup from two aspects: technology and ecology. Only by cultivating more developers, establishing a benign community ecology, and designing technical tools with excellent performance can ZK-Rollup incubate more investment-worthy projects. When we find a new technical narrative, we must also see the status quo of ecological development, which is the most important proposition.

"In the face of investment and development opportunities in the ZK field, it still depends on whether there are leading DApps to rise in the future." It is undeniable that as the infrastructure of the chain, the construction of ZK-Rollup in terms of transactions, loans, stable coins, etc. is still in progress. In the early stage, Teacher Leek looks forward to the birth of new projects on the ZKML track in the future.

For developers, in addition to grasping the investment trend of ZK-Rollup technology, ** need to improve their own development capabilities in order to grasp development opportunities. **Guest teachers present suggested that developers who are interested in ZK-Rollup should further focus on targeted learning of technical documents (to understand the basic principles and algorithm logic of ZK technology); contestants with development experience can try to write ZK-Rollup technology Code, improving technical skills will have a broader perspective. On this basis, Developers should give full play to the technical advantages of blockchain originality and composability, continuously innovate and explore the possibility of technology coupling, so that ZK-Rollup can also shine in the future of Web3 hot!
