Recap | When ZK Meets Guangzhou Youth: A Profound Exchange on the Future of scroll
Abstract:
On December 20th, Scroll joined hands with GXA to host a “hardcore” gathering in Guangzhou. From the in-depth breakdown of ZK principles to the thrilling scaling simulation battle that electrified the audience, we witnessed the power of the next generation of Builders.
Main Content:
On December 20, 2025, the air in Guangzhou was slightly cool. Along the Pearl River, however, a wave of Web3 enthusiasm was quietly heating up.
On this Saturday afternoon, Scroll collaborated with GXA (Guangzhou Blockchain University Student Community) to host the 「Youth Builders Meetup」. It was not a rigid technical presentation, but an in-depth experiment centered on Ethereum scaling, Zero-Knowledge Proofs, privacy computing, and the future form of collaboration.
There were no abstract concept 堆砌 here. From experienced developers to students newly entering the Web3 world, nearly a hundred young Builders gathered, directing their attention to code, mechanisms, and underlying logic.
We chose the most direct way to understand Layer 2—not by listening to “what it is”, but by personally participating in its creation. Through a carefully designed interactive game, everyone experienced the entire process of Ethereum evolving from mainnet congestion to efficient scaling as 「participants」 rather than 「spectators」.
At that moment, technology was no longer cold. It transformed into a future that could be experienced, discussed, and co-constructed.
If you missed the on-site event, this article will take you back to that afternoon of intense ideological collisions and constant inspiration.
01 What is Scroll?
Scroll is a high-performance, secure Ethereum Layer 2 network built for an open economy. Founded on Zero-Knowledge (ZK) Proof technology, it inherits the security of the Ethereum mainnet while significantly improving transaction throughput and confirmation speed, delivering a smoother, low-cost on-chain experience for users.
Unlike many solutions chasing “performance shortcuts”, Scroll adheres to a technical route of high equivalence with Ethereum (zkEVM), maximizing the reproduction of developers’ and users’ real usage patterns on the Ethereum mainnet. This means existing Ethereum applications can almost seamlessly migrate to Scroll without rewriting logic or adapting to new development paradigms.
Meanwhile, Scroll is fully built on open-source infrastructure, with both protocol design and core code open to the community. It is not just a scaling solution, but a public good for Builders: through an open ecological environment, abundant shared resources, and continuous community support, it helps entrepreneurs and development teams accelerate the leap from idea to product.
In Scroll’s view, Layer 2 is not just a “faster chain”, but a crucial step toward a more open, fair, and sustainable Ethereum economy.
02 What is GXA?
GXA Guangzhou Blockchain University Student Community is a blockchain and Web3 learning and innovation community co-initiated by students from Sun Yat-sen University, South China Agricultural University, Jinan University, South China Normal University, Guangdong University of Technology, and Guangdong University of Foreign Studies, open to universities in Guangzhou and even South China.
We are committed to making blockchain spirit truly take root in universities—beyond conceptual popularization, we promote young people to engage with technology itself through systematic learning, real projects, and cross-university collaboration, understand industry operation logic, and participate in the actual construction of the Web3 ecosystem.
GXA takes openness, exploration, and co-creation as its core values: we believe in open-source and collaboration, rejecting empty talk and spectatorship; we encourage a learning path from zero to one and respect in-depth technical exploration; we believe that individual growth and community evolution should nourish each other.
Through technical workshops, Web3 sharing sessions, industry salons, Hackathons, and project incubation, GXA is connecting major universities in Guangzhou to build an open, interconnected, and decentralized youth blockchain network.
Here, blockchain is not a distant future narrative, but a real force that can be learned, practiced, and co-created.
In the wave of decentralization, we choose to unite; in the tide of technology, we choose to create.
03 Hardcore Breakdown: Understand ZK from Scratch
Next was a lecture by Chu Tianying, President of GXA. Titled 「Zero-Knowledge Proofs & Scroll: Reconstructing the Verifiable Future of Blockchain」, this lecture started with a paradox of “trust”—how to complete credible proof without revealing any information—and systematically disassembled the entire process of Zero-Knowledge Proofs (ZK) evolving from cryptographic theory to blockchain infrastructure.
The lecture first addressed Ethereum’s structural dilemma: for the sake of decentralization and security, global nodes must repeatedly execute the same computations, leading to limited throughput, lack of privacy, and unstable user experience. This is not a parameter issue, but an inevitable cost at the architectural level. It is against this background that Rollups, especially ZK Rollups, have become the only path with “deterministic scaling capabilities”.
Through the intuitive “Alibaba’s Cave” thought experiment, we explained the three core axioms of Zero-Knowledge Proofs—completeness, soundness, and zero-knowledge—and further pointed out that the true subversion of ZK lies not only in privacy, but in “computational compression”—replacing global repetitive execution with one expensive computation + one mathematical proof.
On this basis, the lecture deeply analyzed the working principle of ZK Rollup and focused on how Scroll has engineered the “magic of ZK” into practical application: from Scroll Node responsible for transaction sequencing and instant pre-confirmation, to the distributed and specialized Roller Network, and then to bridging and verification contracts that inherit Ethereum’s security, Scroll has built a zkEVM architecture fully equivalent to Ethereum, allowing developers to migrate and deploy applications with almost no learning cost.
More importantly, Scroll has not only pursued theoretical optimality but also directly addressed three major practical challenges of ZK: proof generation speed, system cost control, and developer experience. Through distributed proving, GPU acceleration, recursive proving, and a highly compatible toolchain, Scroll has transformed ZK from a “technology only experts can use” into an infrastructure that is almost “invisible” to developers.
The lecture concluded with a vision of the future supported by ZK × Scroll: from compliant finance, on-chain identity, and high-frequency DeFi, to cross-chain games, L3 ecosystems, and even ZKML (Zero-Knowledge Machine Learning) and privacy public infrastructure. A clear trend is emerging—ZK is evolving from an “optional feature” to the “default architecture for verifiable systems”.
Just as HTTPS is to the Internet, ZK is becoming the universal language of the blockchain world. Scroll’s choice is not “ZK-first”, but “developer-first”: hiding complex cryptography behind the system, allowing every Builder to focus solely on creation itself.
The next decade of blockchain will be a decade of verifiability. And ZK is the underlying answer to this verifiability.
04 Scroll Ecosystem: Latest Progress and Open Economy Vision
At this offline exchange, Scroll guests sorted out the most important recent developments of the Scroll ecosystem and comprehensively demonstrated the panoramic view of the “open economy” that Scroll is building, covering infrastructure, privacy finance, stablecoin innovation, and ecological support.
The lecture first introduced the latest Galileo upgrade of the Scroll mainnet. As the third major update this year, Galileo is fully compatible with Ethereum’s latest execution layer changes, significantly improving network robustness and ZK proof performance while maintaining low fees: including more complete EVM compatibility, a more refined rollup fee structure, and approximately 50% compression in proof cycles. This upgrade marks a key step forward for Scroll in terms of security, performance, and infrastructure maintainability.
Subsequently, it focused on Scroll’s native privacy solution, Cloak. Cloak is not an “extreme privacy tool”, but aims to be auditable, compliant, and implementable, introducing Zero-Knowledge Proofs into real financial and consumption scenarios. Based on Scroll L2 and Validium architecture, Cloak enables privacy protection for on-chain transactions while maintaining verifiability, and supports gas-free and real-world payments. Currently, multiple application chains including cross-border payments and privacy consumption cards have been launched on Cloak, proving that “practical privacy” is becoming a reality.
The ecological part showcased a batch of rapidly growing applications on Scroll: from the one-stop DeFi platform Honeypop, to ether.fi CashCard with a transaction volume exceeding 100 million US dollars, to the “wallet-free, gas-free” savings application Polystream for ordinary users, as well as the AI-based yield engine SynthOS and social payment tool ChatterPay. The Scroll ecosystem is constantly extending to real users and high-frequency scenarios.
Finally, the lecture introduced Scroll’s entrepreneurship and developer support program, OpenEconomy. This program is committed to helping developers move from “writing code” to “building products and companies”, providing long-term, systematic entrepreneurial support for technical creators through forms such as Open Campus Accelerator and Vibe Code Camp.
Overall, this sharing not only demonstrated Scroll’s latest progress in ZK infrastructure, privacy finance, and ecological construction, but also clearly conveyed a signal: Scroll is not just a Layer 2, but is building a truly usable and sustainable open economic foundation for developers and users.

Scroll Scaling Game: When Scaling Mechanisms Are Actually “Run”
If technical sharing solves the problem of “understanding”, then Scroll Scaling Simulation aims to answer another question:
What happens to the blockchain when we actually put people into the network?
At this event, through an interactive simulation, we decomposed the key mechanisms of Ethereum’s evolution from the congested L1 era to the efficient Scroll L2 era into three consecutive on-site experiences.
Starting with “Transaction Waiting”: Everyone is a NodeBefore the game began, the venue entered a seemingly relaxed state that was actually operational.
Participants freely picked up tasks, completed operations, and retained screenshot evidence—this period corresponded to the mempool phase before transactions enter the blockchain.
Many people did not realize at first:
“Waiting + uncertainty” is itself part of the blockchain experience.
And this laid the groundwork for subsequent verification and game theory.
Round 1: Experience ZK’s Mathematical Trust with "Timestamps"In the first phase, all valid actions needed to be “proven” in an extremely simple yet rigorous way.
Participants were required to submit screenshots with timestamps within a specified time as proof of completing their tasks. Instead of repeatedly asking “how did you do it”, the scene only focused on one thing:
Can it be verified?
This mechanism directly corresponds to the ZK Validity Proof approach adopted by Scroll: instead of relying on all nodes to recheck, it only needs to verify the correctness of the proof itself.
Many participants feedback that this was the first time they understood the value of Zero-Knowledge Proofs beyond code.
Round 2: When Only “Human” Consensus RemainsSubsequently, the game deliberately removed technical verification, leaving only “human” judgment.
Each participant needed to stand up to explain the reasons for their actions and cast their Gas chips to those they “were willing to trust”.
This phase highly restored the social consensus model in early L1 or DAO governance:
People with louder voices are more likely to be remembered;Expressive ability affects outcomes;Consensus formation is slow and unstable.
The chaos and uncertainty on site made many people intuitively feel that when consensus cannot be programmed, the system is inevitably costly.
Final Phase: Sequencers Make the Network "Suddenly Faster"In the final round, three participants were selected as “sequencers”.
They needed to collaborate to complete a high-density result packaging and confirmation within a very short time based on all the information from the previous two rounds.
This process simulated Scroll’s high-performance sequencer mechanism: achieving a leap in throughput through batch processing and rapid confirmation.
When the final result was completed before the countdown, the feedback on site was not “the rules are completed”, but—the network actually ran.
Beyond the Mechanism: What Remains?This game did not have a complex reward design, but it brought about very clear cognitive changes for many participants after the end:
ZK is not “more esoteric cryptography”, but lower-cost trust;The problem with L1 is not just slowness, but the consensus method itself;Scroll’s value lies in leaving complexity to the system and giving certainty to users.
As summarized on site:
What Scroll does is not replace trust, but make “verification” the default option.
If you want to truly understand scaling next time, you may not need to read the whitepaper first. Just put yourself into the network.
06 Networking: Ideas and Creativity Grow in Collision
Beyond technical sharing, the networking session of this event became the most active part. Nearly a hundred developers, entrepreneurs, and student Builders formed groups freely, engaging in enthusiastic discussions around Scroll, Cloak, USX, and the Web3 ecosystem.
This was not just “chatting”, but a collision of real value:
Developers exchanged technical implementation details on site, sharing experiences with zkVM and Rollup;Entrepreneurs and students provided rapid feedback on project ideas, inspiring multiple potential cooperation paths;Many participants established connections in a relaxed atmosphere, paving the way for subsequent Hackathons, ecological projects, or entrepreneurial plans.
We saw that the networking session truly achieved the goal of “from information absorption to actual connection”: participants came with questions and left with inspiration; ideas collided in discussions, and creativity incubated in interactions.
As stated in the original intention of the event: in the wave of decentralization, the connection between people is also an important part of ecological growth. This exchange truly released the energy beyond theory and technology.
Conclusion: This Is Just the Starting Point
The event drew to a close amid enthusiastic Networking. As night fell and the lights along the Pearl River lit up, everyone’s enthusiasm for discussion showed no sign of abating.
Some were discussing how to develop privacy payment DApps using Cloak, some were asking about the time of GXA’s next event, and others were reviewing the game theory strategies from the earlier game.
