Sitting in a café over the weekend, flipping through the introduction of the GSUI Staking ETF just disclosed by Grayscale Investments, my mind was filled with excitement because the #Sui ecosystem is among the top five in our crypto holdings, and this milestone will bring new opportunities!

For the past two years, there has been a debate in the market about the public chain route. Some bet on the L2 system of ETH, while others bet on the high-performance route of Solana. But by 2026, Sui seems to be quietly following a completely different path.

I am increasingly feeling that Sui's "S2 strategy" + the launch of the ETF could be the most worthwhile core line for long-term tracking and study this year. Below are some of my fragmented thoughts as an observation notebook📒.

1️⃣ #Sui is no longer playing with "modularity," but creating a complete system

The most popular term in the blockchain industry in recent years has been modularity. Simply put, it means breaking down different functions, such as transactions on one chain, data on another layer, and computation on another layer.

The theory is elegant, but using it in practice can be quite cumbersome. Users and developers often have to deal with various L2s back and forth, cross-chain, bridges, liquidity fragmentation... the experience is not ideal.

Sui's approach is exactly the opposite; instead of breaking things apart, it integrates everything.

Now, the Sui protocol stack looks something like this, with #Walrus responsible for data storage, #DeepBook providing the on-chain order book, and #Seal building the privacy infrastructure for the ecosystem, all layered within the same architecture.

This logic feels a bit like the evolution of operating systems in its early days. Many early computers required plugins for various functions, but later systems built these features directly, making it easier for users and developers, and giving large companies more confidence. For traditional institutions, the simpler the underlying architecture, the better; what they often fear is that the base is too complex, leading to uncontrollable stability issues.

2️⃣ RWA + Privacy is actually the key for institutional entry

Many people have been talking about RWA, but few have seriously considered a question: "If everything on-chain is completely transparent, why would institutions come?"

Imagine if a fund bought government bonds, corporate bonds, or private assets on-chain, and all competitors could see their positions in real-time—pretty much no one would dare to play.

Thus, many public chains have been studying ZK privacy over the past two years. Sui's development approach is very pragmatic; Seal has created a dedicated privacy infrastructure for the Sui ecosystem, utilizing cutting-edge cryptographic technologies such as ZKP, homomorphic encryption, and multi-party secure computation to address privacy issues. It acts as a middle layer, allowing privacy features to be easily integrated into existing DApps through simple API calls, enabling users to choose the level of information disclosure on-chain. Information that needs to be shown to regulators can be shown while keeping what shouldn't be public private, which is undoubtedly significant for traditional institutions.

If a public chain can first establish such a Web3 environment where assets can be on-chain, transaction efficiency is higher, privacy can be protected, and compliance is assured, then traditional institutions like Goldman Sachs or BlackRock may genuinely be able to move funds onto the chain. Many think the challenge with RWA is technical, but it is more about institutional frameworks and privacy boundaries.

3️⃣ AI Agent + Blockchain, Sui's structure is somewhat naturally adaptable

One of the hottest narratives in 2026 is actually not AI itself, but AI Agents, such as the popular Openclaw this year, which allows AI to perform tasks autonomously, like automatically subscribing to data, executing trades, automatically settling, and paying service fees.

The issue is that most blockchains are not designed for the "machine economy." However, Sui has a very unique structure—Object Model. In this system, each asset is an "object." Just like files on a computer, they can be directly called, transferred, and combined.

This is very friendly for AI. For example, imagine your AI assistant purchasing a dataset online: AI automatically places an order—pays with stablecoins—completes the asset transfer.

If the GAS fee is zero (thanks to Sui subsidies), then it can be said that the user experience throughout the process is essentially seamless. As transactions between machines begin to occur frequently, this efficiency will become very important.

4️⃣ GSUI Staking ETF, truly starting to change the entry points of funds

What made me stop and think for a long time in the café was actually this: Grayscale's launch of the GSUI Staking ETF on the NYSE Arca, which I believe has been underestimated by many in terms of its impact.

First, Wall Street can now buy public chain assets; currently, the biggest problem for traditional capital is not cognition but the operational threshold. Many institutions are unwilling to manage private keys, use on-chain wallets, or do the staking themselves.

The introduction of GSUI essentially hides all these complicated operations; you only need to buy it through a brokerage account.

Secondly, the ETF includes staking returns; previously, many crypto ETFs only tracked prices. However, if the ETF can include staking profits, then the logic changes.

It resembles a digital asset with cash flow. For institutional investors, this is crucial, especially during market downturns where steady cash flow returns are vital.

Lastly, there is attention from institutions towards the entire Sui ecosystem; currently, the market is not just focusing on SUI itself. Ecosystem components like #Walrus and #DeepBook are also starting to be seen as a whole. If future funds are allocated based on "ecosystems," then Sui will be positioned more like a blockchain operating system.

In summary, I am now heavily invested in #Sui and its ecosystem; the core logic no longer sees it as an ordinary public chain. It feels more like a foundational infrastructure for future finance and AI.

When viewed from different perspectives, in terms of technology: AI Agent's automatic payments and machine economy. In terms of funds: inflows from the GSUI ETF. Ecological perspective: Sui Stack (storage + liquidity + privacy). Throughout the Web3 public chain space, it’s rare to see such a comprehensive public chain logic.

My investment philosophy is simple. Such high-level infrastructure projects are often not about making money through short-term trading. They need to be held gradually, waiting for the narrative to mature. Moreover, the institutional locks for Sui will be fully unlocked this year, so there will be no institutional selling pressure in the future, allowing me to wait for its fruitful results over the next four-year cycle.🧐
