Navigating the Way forward for Cross-Chain Interoperability: An Interview with Dr. Weijia Zhang

By Bradley Stone, EEA Analysis Lead

“It’s an thrilling but difficult time, and we wish to increase the working group, particularly with the rising significance of cross-chain interoperability within the business.”

Cross-chain interoperability is outlined as the power to switch property from one blockchain to a different, ship and obtain messages throughout blockchains, and provoke actions throughout a number of blockchains. Because the blockchain house evolves, cross-chain communication has change into one in every of its most vital facets. This consists of working inside the context of public Ethereum blockchains.

In a dialog with Weijia Zhang, Chair of the EEA Crosschain Interoperability Working Group and Vice President of Engineering at  Wanchain, we delve into the alternatives, challenges, and way forward for cross-chain use instances, DeFi, and requirements. Right here’s what he needed to say:

Weijia, what’s the present state of cross-chain interoperability, and the way is the Crosschain Working Group addressing it?

A: Now we have printed paperwork outlining cross-chain interoperability use instances and tips to assist educate decision-makers and groups on implementing cross-chain expertise with security as a prime precedence. Ongoing work expands upon these efforts and consists of specs that we hope will quickly be adopted by the business as interoperability requirements. It’s an thrilling but difficult time, and we wish to increase the group, particularly with the rising significance of cross-chain interoperability within the business.

You’ve written a textbook and at the moment lead the Sensible Contract Growth course on the College of Texas as an adjunct school. How do you make beneficial content material on this new and continually altering subject?

Educating affords distinctive challenges. College students of blockchain expertise are wanting to be extra concerned in enterprise-level improvement however typically discover themselves drawn exterior of the business. Usually, college students be part of a pilot blockchain mission with a serious company solely to see that mission lose funding or fall off the map in beneath two years. A lot of that’s nonetheless depending on financial circumstances, additionally constrained by the regulatory setting. Nevertheless, the effectiveness of coaching and academic supplies can also be at odds with the velocity of recent developments within the business. Blockchain-related expertise is evolving at a fast tempo. All of this solely accentuates the necessity for satisfactory coaching and training. The ecosystem is behind in hiring folks with the proper expertise, and this hole should be crammed.

Improvements like ZK and layer-two supply options to a few of the most important issues holding again mass adoption of Ethereum, but challenges persist. Are you able to increase on this?

A: ZK could successfully remedy the privateness challenge, however scalability stays a priority on a number of ranges. Nonetheless, the ecosystem is making progress. Ethereum 2.0’s success and improvements like ConsenSys zkEVM are promising indicators. Ethereum’s clean transition to proof-of-stake consensus, the large power financial savings, and the numerous efficiency enhancements improve Ethereum’s enterprise readiness. 

Lastly, Weijia, what’s your outlook on the way forward for cross-chain interoperability?

It’s complicated, however I’m optimistic. We should standardize specs, proceed innovating, and take note of regulation areas. 

Upcoming Hackathon & Name for New Working Group Members
