Overcoming challenges in on-chain capital markets

To achieve on-chain capital markets, it’s essential to address the challenges of settlement finality and privacy for issuers.

— Yuval Rooz
Convincing issuers to move their records on-chain requires solving settlement finality and privacy issues.
You need to be able to convince issuers to move their books and records to be natively on chain.

— Yuval Rooz
Privacy concerns are a significant barrier for issuers considering on-chain solutions.
How do you give settlement finality and get an issuer to be comfortable if they don’t want their books and records to be public?

If people really had those topics deep in their heart and really said that this is not good for the industry, I would say that those topics would have come about.

— Yuval Rooz
Misconceptions about Canton being a centralized database are incorrect.
Some of the things that have been said, Canton is a centralized database with a coin on top of it, are all things that are not true.

— Yuval Rooz
Understanding what constitutes a centralized versus decentralized network is essential.
Criticism often stems from perceived biases against certain projects.
This insight provides a strong viewpoint on the nature of criticism in the crypto industry.
