In August this year, Japanese electronics giant Sony officially announced the launch of its Ethereum Layer 2 expansion, Soneium.

Four months later, German banking giant Deutsche Bank also officially announced the launch of its own Ethereum Layer 2 expansion.

For a detailed introduction to this news, you can refer to the PANews article linked at the end.

This news was announced by the Head of Application Innovation for Deutsche Bank's Asia-Pacific region, with the project named Project Dama 2. Its beta version was launched as early as November, and the official version is expected to be released next year after regulatory approval.

The Layer 2 expansion launched by Deutsche Bank is built on the zkSync Stack architecture, and there are two main features that I find particularly interesting:

First, it uses Soulbound Tokens to establish digital identity.

Second, it employs a Paymaster to allow users to pay network fees.

Soulbound Tokens were a popular technology a year or two ago.

I remember when this technology was first introduced, project teams and users in the ecosystem primarily viewed it as a way to issue various honor tokens, such as recognizing users for participating in events or receiving rewards.

At that time, people's imagination about it was quite narrow, so the hype didn't last long, and few people mentioned it again, let alone launched any large-scale applications based on this technology.

Now, this project uses it to establish users' digital identities, which feels very similar to representing traditional bank personal user information with Soulbound Tokens.

This perspective is significantly different from before. Although this is purely a centralized application, it allows this technology to serve a purpose that was previously unimagined.

So sometimes, the application of technology can truly exceed our imagination—it's possible that the A scenario we long for takes a long time to materialize, but the B scenario we never considered has already come to fruition.

Paymaster is a tool that I really like. I just mentioned this application in a recent article. Its biggest feature is that it allows users to choose other tokens (non-mainnet tokens) to pay transaction fees.

The scenario where I use this tool most frequently is in the zkSync Layer 2 expansion. In these Layer 2 expansions, when I swap various tokens on a DEX and need to pay fees, I usually don't choose ETH but rather some smaller tokens.

This tool provides great convenience for users while also empowering tokens.

One can imagine that if this tool is used in Deutsche Bank's Layer 2 expansion, users could completely pay transaction fees with various stablecoins supported by Deutsche Bank, without needing to use Ethereum.

For ordinary users, they might not even feel the presence of Ethereum or even blockchain. What they see are just various stablecoins on-chain: such as USDC, Euro stablecoins, and so on.

Compared to Sony's use of OP Stack technology to build its own Layer 2 expansion, Deutsche Bank chose zkSync. I think the main reason here is likely due to security considerations.

Layer 2 expansions based on zkSync technology do not require a 7-day waiting period, and each transaction can be confirmed in real-time, which is much better in terms of security, but still lacks efficiency. It sacrifices efficiency for security.

I recall a reader commenting at the end of a recent article, asking whether it is worth holding Starknet tokens now.

Initially, I was optimistic about zkSync being far superior to OP. However, the development of the two ecosystems has shown a clear divergence, with zkSync lagging behind OP, leading me to question whether zkSync would have a chance to catch up in the future.

Looking at it now, if the financial industry, especially financial sectors like banks, follow Deutsche Bank's lead in entering Ethereum's Layer 2 expansions, they will likely choose zkSync based on security considerations. If this trend continues, zkSync still has significant opportunities, though it may take some time.

I still hold all tokens related to zkSync Layer 2 expansions and have never sold any.

I look forward to the resurgence of zkSync technology.

Our Twitter account was recently banned again; this is the second time we've been banned.

We are quite helpless and confused about this: we have never posted inappropriate comments on Twitter, rarely interacted with other accounts, and have not engaged in any commercial activities. We do not understand which rule we violated.

However, we have registered a new Twitter account purely to back up our articles and to provide an open space for communication with our readers.

Our new Twitter account is @Dao_Views.

This Saturday (January 4, 2025), we will hold our first online discussion on this new Twitter account, and everyone can post their questions in the comments under the following link.
