EWHA-CHAIN 18th Cohort | 4th Regular Session Recap ✨

On October 06, EWHA-CHAIN held its fourth regular session at Ewha Womans University with @namyura_ from Sentient.

The first part of the session focused on the limitations of a closed AI ecosystem dependent on a few tech y of Open AI. Yura introduced Sentient’s core initiatives, detailing how to protect open-source contributors' rights through Ownership and Provenance proofs, as well as the impact of Harness improvements on AI performance.

The second part shifted to building an open-source ecosystem and proving AI model ownership utilizing Fingerprinting technology. She shared diverse insights, introducing the ARENA platform and EvoSkill—which continuously improves itself through inter-agent learning—along with open AI infrastructure like ROMA and builder support programs.

We sincerely thank Yura Nam for sharing her experiences and valuable insights with us.

And thank you to everyone who joined us for the session!

Had an amazing session with @Ewhachain at Ewha Womans University 🏫

Spoke to a room full of brilliant students about a question I keep coming back to:

If AI models can be copied in minutes — who actually owns them?

That's the problem @SentientAGI is solving.

Covered a lot of Why AI infrastructure is dangerously concentrated
→ How fingerprinting proves model ownership
→ What open-source AI actually looks like in practice (EvoSkill, Arena, ROMA)

Huge thank you to everyone who showed up and asked such thoughtful questions : ) And stay tuned with @sentient_found 's upcoming updates!

EWHA-CHAIN 18th Cohort | 2nd Regular Session Recap ✨

On September 15, we held our second regular session at Ewha Womans University under the theme, “Solana’s Perspective on STOs & RWAs: Opportunities in the Korean Market.”

This session explored the evolving landscape of on-cemergence and business models of stablecoins to the growing connection between RWAs and DeFi.

We also looked at global RWA cases and Korea’s evolving token securities landscape, exploring how Solana connects traditional finance with public blockchain infrastructure and the opportunities this presents in the Korean market.

A special thank you to Chaerin Kim (APAC Tech, Solana Foundation, @decentra1ized_) for sharing valuable insights and experiences with us.

Thank you to everyone who joined us!

📊 On-Chain Data Analysis Project with Google Cloud 📊

Undergraduates rarely get the chance to work with real enterprise infrastructure. In this program, our members queried raw Ethereum and Solana transactions directly from BigQuery's public datasets.

Our sincere thanks to iiiiiiii for making this possible 💚

🧐 Two members documented what they found working directly with Google Cloud BigQuery.

① The Enterprise Blockchain Design Dilemma — Chaeyun Cho (17th cohort, Computer Science '23)
Across roughly 16.45M valid contract calls on Ethereum (Jun 2 – Jul 1, 2026, excluding simple transfers), USDT and USDC alone accounted for over 75%. From there, the piece works through on-chain bottlenecks and the trade-offs of each mitigation pattern.

② On-Chain Data Analysis: Weeks 1–2 — Yeju Jang (School of Software, Eltec College of Engineering)
A working log comparing Ethereum and Solana across usage, reliability, and active addresses.
🔗 bit.ly/gcp-bigquery
🔗 GitHub — github.com/yeju0829/ewha-…

Learning Points
📌 A failed hypothesis is still a result — We expected fees to rise with transaction volume. Over the period we examined, that didn't hold.
📌 Most of the work happens before you reach the data — Dataset subscription steps, free-tier quotas, type errors in the visualization layer. Clearing these one by one was a large part of the job.

EWHA-CHAIN is a student organization built around hands-on industry projects.

Thank you to every partner who worked with us and to all our 17th cohort members — and please look forward to what our 18th cohort takes on next.

Thank you 💚

✍ Google × Solana AI Agentic Workshop recap, and our hands-on notes

On August 31, the @googlecloud × @SolanaFndn AI Agentic private workshop was held at Google's Seoul office. Fintech and financial institutions, along with companies building agent businesses, gathered to work d AI and Solana's payment rails connect in practice.

📍 Part 1 ㅣThe New Agentic Economy with Google Cloud AI × Web3
@Jimiiiiiiiiii (Web3 Account Manager) made the case for why agentic commerce, and why now. She covered the approach of treating open protocols and crypto as a payment interface agents can read, illustrated with pay.sh, co-launched with the Solana Foundation. She also walked through the neutrality strategy behind donating ADK, A2A, and AP2 to external foundations — lowering adoption barriers without locking anyone into a single vendor.

📍 Part 2 ㅣAgent Payment on Google Cloud
Seongyul Bae (Customer Engineer, Cloocus) covered how AP2 actually gets implemented. He explained the structure that replaces screen-based authentication with headless signed mandates: the user signs once, the scope of amount, duration, and payment method is carried in the mandate, and that scope is independently verified at settlement. He also ran a live demo of an agent autonomously purchasing external data to deepen its analysis, and laid out — from a practitioner's view — what enterprises should prepare before adopting AP2.

📍 Part 3ㅣBlockchain as the New Payment Infrastructure for the Agent Economy
@decentra1ized_ (APAC Tech, Solana Foundation) covered why blockchain becomes the financial rail for agent payments. She walked through how smart contracts, stablecoins, and wallets together make verifiable payment possible without a bank account, and closed on AP2 and x402 as complements rather than rivals — AP2 handling trust and authorization, x402 handling execution.

Thanks to Google, Solana, Superteam Korea, and Cloocus for making this happen, and to Jimi Lee, Chaerin Kim, @kristintto, and Scott Lee. 🙇‍♀️

Meanwhile, EWHA-CHAIN has spent the past two months implementing and studying these layers hands-on.

※ All four club projects are learning demos. No real sales, payments, or transfers occurred.

① How it gets built — Google Antigravity 2.0 (Yurim Kim, Artificial Intelligence 7C4lLeIJ
② The merchant contract — UCP (Ayoung Seo, Artificial Intelligence)
👉 github.com/say-117/UCP-de…
③ Agent-to-agent communication — A2A (Sooji Lim, Business Administration)
👉 bit.ly/google-a2a
④ Payment authorization — AP2 (Siwon Choi, Computer Science & Engineering)
👉 github.com/SiwonChoi25/Fl…

Who verifies the delegation scope?
Who cleans up the catalog so machines can read it?
And where does human approval need to remain?

The questions we ran into while building turned out to overlap exactly with what the industry was discussing at the workshop.

The questions we ran into while building found their place one by one through this workshop. It gave us a much clearer sense of where agentic commerce is heading, and we'll keep studying this space and sharing what we learn.

There's still far more to learn, but these two months gave us a real sense of the structure agentic commerce is being built on. We'll keep following where it goes. 🌝✍️
