After discussing RWA, let's talk about something noteworthy on ETH and Solana.

Let's Start with ETH

One of the most noteworthy things on ETH is Justin's earlier proposal of Native Rollup, which is an extension of the current Based Rollup, with significantly increased implementation complexity.

First, let's briefly talk about Based Rollup -

This is what Puffer/Taiko is working on. Compared to traditional L2, the sequencing rights are given to L1. The main advantages are twofold: first, L1 can capture more value, and second, all Based Rollups theoretically achieve interoperability.

Initially, I had doubts about the interoperability aspect. However, when I spoke with a team working on a Based Rollup project and asked the Founder about it, it was confirmed that interoperability is indeed achievable. This is because within any 12-second Slot on L1, a specific selected validator is responsible for block production, and all Based Rollup sequencing is handled by that selected validator, allowing these Based Rollups to achieve interoperability.

However, two subsequent issues arise:

1. The current major L2 solutions that hold crucial positions may have no motivation to transition to Based Rollup.

2. If in the future there are dozens or even hundreds of Based Rollups, then the burden on the validator responsible for block production on L1 each time would be significantly increased. Their hardware requirements would undoubtedly need to be much higher than they are now. Also, since validators are randomly selected, it means that the hardware requirements for all Candidates would need to keep up. Otherwise, you wouldn't be able to handle the sequencing of dozens or hundreds of L2 solutions. This would inevitably have a substantial impact on the decentralization of the ETH Validators.

Regarding these two concerns, I welcome everyone to leave me a comment to exchange ideas and discuss.

Let's Talk About Native Rollup

While Based Rollup delegates sequencing rights to L1 validators, Native Rollup delegates the proof system to L1 validators by introducing a precompile to make L1 aware of the state transitions within each block of the Native Rollup (this precompile likely needs to be added in a hard fork upgrade at some point). Initially, the proof system uses Re-execution (where L1 validators run transactions themselves) as the starting solution, with Real-Time Proving (based on Snark proof) as an optimization strategy later on. However, this would require a significant advancement in ZK technology (being able to produce a block proof in a few seconds, which is currently far from reality, probably requiring at least 3-5 more years).

Native has three noteworthy aspects

1. One thing worth mentioning is that you will find that this is actually quite similar to ETH's original scaling solution. Isn't this Rollup? Isn't this sharding?

2. Another point is that you will find ETH and Solana have intersected at a certain point. Solana's two scaling projects, MagicBlock's Ephemeral Rollup and Lollipop's Extended Execution Layer, share some similarities with Native Rollup's concept, giving a sense of sharding

3. The third point, which I am not entirely 100% sure about but I believe/hope is the case, is that Native Rollup and projects like MagicBlock provide a user experience where users do not need to switch networks. This means that on MetaMask/Phantom, you will always stay on ETH/Solana L1, and your assets will not go through the bridging process to move between L2. Native/Ephemeral Rollup acts as an external execution layer to perform computations, settling automatically on L1, thereby avoiding liquidity silos

However, the ideal is always abundant, the reality is harsh. Not to mention the technical challenges and implementation timeline, just the existing Layer 2 benefits territorial issue makes it difficult for people to be optimistic. The development of the crypto world has moved beyond the cypherpunk spirit and tech utopianism, and now resembles different factions

As for the upcoming Prague upgrade next month, there are already numerous online articles interpreting it, so I won't elaborate further here. Hopefully, after this upgrade, EIP-7702 can resolve the chaos caused by various account abstractions in different EIPs and present a chain-level ultimate solution. However, whether end-users and developers will bear the consequences is Another Story

Now, let's talk about Solana

Recently, two notable things about Solana are worth mentioning

One of them is the recently popular SIMD-0228 proposal

The proposal is mainly about changing Sol's current inflation, transitioning from a fixed 15% yearly reduction in issuance to an inflation rate dynamically adjusted based on staking rate

In general, it has the following features

1. MEV (Miner Extractable Value) income enhancement (Solana's MEV income in Q4 2024 was 10 times higher than in Q1, but with Pump.fun cooling down, I am quite curious about the MEV income level in 2025)

2. Implemented Dynamic Increase, with three equilibrium points set at 65%, 50%, and 33% based on the staking ratio

3. The new proposal is not overly detrimental to small and medium validators

4. It can be seen that Solana is also transitioning from "overpaying for security" to "finding the minimum necessary payment"

This proposal ultimately failed because it did not receive the required 66.7% majority vote, but it was close as it received around 61%.

Although the proposal did not pass, there are two interesting points worth mentioning:

1. Anatoly did not seem too discouraged. He believes that "Solana's governance needs to be fast and decisive, and quick governance actions will be key to seeking better solutions." In other words, the failure of SIMD-0228 to pass also reflects the efficiency of Solana's network governance. This proposal, from initiation by Multicoin to community discussion to the end of the vote, took only about a month. "Quick approval/failure," and then on to the next one, which is crucial for the rapid evolution of Solana.

2. Chinese media's interpretation of the inflation rate in this proposal was almost entirely incorrect. The vast majority of Chinese media, including Chinese Twitter, interpreted the inflation part of this proposal as "reducing inflation by 80%," meaning that under the current staking rate of around 65%, inflation would be reduced from around 4.8% to around 0.8%. When I first saw this, I was shocked, and after checking several sources, they all had the same interpretation! How could this be possible without causing validators to revolt! Even if Mev income comes in, with the inflation income instantly reduced by 80%, Validators would be on the verge of a strike... I then checked the original proposal and the interpretation of English-speaking community leaders, and it should actually reduce from 4.8% to around 4% under the current staking rate, rather than directly to 0.8%. I guess the author of an early interpretation article in the Chinese community misread the formula, directly understanding it as reducing to 0.8%, and then all the media outlets and KOLs copied that misconception, leading to a collective misunderstanding...

The second thing to mention is not actually news but something that has been around since 2024, yet I learned about it for the first time while chatting with a founder of an RWA project on Solana. That is the Solana Token Extension, which many may not be aware of, so I will share it here:

Solana Token Extension - A next-generation SPL token standard, meaning a token solution at the Solana chain level, includes features such as privacy transactions (only amount privacy, with both parties unable to hide the transfer), transfer hooks (e.g., requiring KYC, enforcing royalties), non-transferable tokens (similar to SBT), interest-bearing assets, metadata, and so on, totaling 19 features that can be freely combined and used.

This is also why the RWA project adopted Solana as its main blockchain. In addition to high TPS, Solana has chain-level native privacy, KYC, and other token standard solutions that are composable. This is much more flexible than various ERC standalone token standards on the ETH side. For blockchain projects like the next-generation Move chain, it is currently not possible to have such rich native-level usability, making Solana their only choice. This has also strengthened my confidence in Solana. Beyond supporting projects like Pumpfun and Meme, I believe that leveraging Token Extension on Solana can lead to many meaningful projects.

Finally finished talking about ETH and Solana. This weekend, I will write the last post in this series, reflecting on Crypto X AI in 2025.

$COIN Joins S&P 500, but Coinbase Isn't Celebrating

On May 13, S&P Dow Jones Indices announced that Coinbase would officially replace Discover Financial Services in the S&P 500 on May 19. While other companies like Block and MicroStrategy, closely tied to Bitcoin, were already part of the S&P 500, Coinbase became the first cryptocurrency exchange whose primary business is in the index. This also signifies that cryptocurrency is gradually moving from the fringes to the mainstream in the U.S.



On the day of the announcement, Coinbase's stock price surged by 23%, surpassing the $250 mark. However, just 3 days later, Coinbase was hit by two consecutive events: a hack where employees were bribed to steal customer data and a demand for a $20 million ransom, and an investigation by the U.S. Securities and Exchange Commission (SEC) into the authenticity of its claim of having over 100 million "verified users" in its securities filings and marketing materials. These two events acted as mini-bombs, and at the time of writing, Coinbase's stock had already dropped by over 7.3%.


Coincidentally, Discover Financial Services, being replaced by Coinbase, can also be considered the "Coinbase" of the previous payment era. Discover is a U.S.-based digital banking and payment services company headquartered in Illinois, founded in 1960. Its payment network, Discover Network, is the fourth largest payment network apart from Visa, Mastercard, and American Express.


In April, after the approval of the acquisition of Discover by the sixth-largest U.S. bank, Capital One, this well-established digital banking company of over 60 years smoothly handed over its S&P 500 "seat" to this emerging cryptocurrency "bank." This unexpected coincidence also portrayed the handover between the new and old eras in Coinbase's entry into the S&P 500, resembling a relay race scene. However, this relay baton also brought Coinbase's accumulated "external troubles and internal strife" to a tipping point.


Side Effects of ETFs


Over the past decade, cryptocurrency exchanges have been the most stable "profit machines." They play a role in providing liquidity to the entire industry and rely on trading fees to sustain their operations. However, with the comprehensive rollout of ETF products in the U.S. market, this profit model is facing unprecedented challenges. As the leader in the "American stack," with over 80% of its business coming from the U.S., Coinbase is most affected by this.



Starting from the approval of Bitcoin and Ethereum spot ETFs, traditional financial capital has significantly onboarded users and funds that originally belonged to exchanges in a more cost-effective, compliant, and transparent manner. The transaction fee revenue of cryptocurrency exchanges has started to decline, and this trend may further intensify in the coming months.


According to Coinbase's 2024 Q4 financial report, the platform's total trading revenue was $417 million, a 45% year-on-year decrease. The contribution of BTC and ETH's trading revenue dropped from 65% in the same period last year to less than 50%.


This decline is not a result of a decrease in market enthusiasm. In fact, since the approval of the Bitcoin ETF in January 2024, the inflow of BTC into the U.S. market has continued to reach new highs, with asset management giants like BlackRock and Fidelity rapidly expanding their management scale. Data shows that BlackRock's iShares Bitcoin ETF (IBIT) alone has surpassed $17 billion in assets under management. As of mid-May 2025, the cumulative net inflow of 11 major institutional Bitcoin spot ETFs on the market has exceeded $41.5 billion, with a total net asset value of $1214.69 billion, accounting for approximately 5.91% of the total Bitcoin market capitalization.

Institutional investors and some retail investors are shifting towards ETF products, partly due to compliance and tax considerations. On one hand, ETFs have much lower trading costs compared to cryptocurrency exchanges. While Coinbase's spot trading fee rate varies annually in a tiered manner but averages around 1.49%, for example, the management fee for IBIT ETF is only 0.25%, and the majority of ETF institution fees fluctuate around 0.15% to 0.25%.



In other words, the more rational users are, the more likely they are to move from exchanges to ETF products, especially for investors aiming for long-term holdings.


According to multiple sources, several institutions, including VanEck and Grayscale, have submitted applications to the SEC for a Solana (SOL) ETF, with some institutions also planning to submit an XRP ETF proposal. Once approved, this may trigger a new round of fund migration. According to a report submitted by Coinbase to the SEC, as of April, the platform's trading revenue from XRP and Solana accounted for 18% and 10%, nearly one-third of the platform's fee revenue.



However, the Bitcoin and Ethereum ETFs passed in 2024 also reduced the fees for these two tokens on Coinbase from 30% and 15% to 26% and 10%, respectively. If the SOL and XRP ETFs are approved, it will further undermine the core fee revenue of exchanges like Coinbase.


The expansion of ETF products is gradually weakening the financial intermediary status of cryptocurrency exchanges. From their original roles as matchmakers and clearers to now gradually becoming mere "on-ramps and off-ramps" for funds, exchanges are seeing their marginal value squeezed by ETFs.


Robinhood Takes a Stand, Traditional Brokerages Join the Fray


On May 12, 2025, SEC Chairman Paul S. Atkins gave a keynote speech at the Tokenization and Cryptocurrency Working Group roundtable. The theme of his speech revolved around "It is a new day at the SEC," where he indicated that the SEC would not approach enforcement and regulation the same way as before but would instead pave the way for cryptocurrency assets in the U.S. market.



With signs of cryptocurrency compliance such as the SEC's "NEW DAY" declaration, an increasing number of traditional brokerages are attempting to enter the cryptocurrency industry. One of the most representative cases is the well-known U.S. brokerage Robinhood, which began expanding its crypto business in 2018. By the time of its IPO in 2021, Robinhood's crypto business revenue accounted for over 50% of the company, with a significant boost from the Dogecoin "moonshot" promoted by Musk.


In Q1 2025 earnings report, Robinhood showcased strong growth, especially in revenue from cryptocurrency and options trading. Fueled by Trump's Memecoin, cryptocurrency-related revenue reached $250 million, nearly doubling year-over-year. Consequently, Robinhood Gold subscription users reached 3.5 million, a 90% increase from the previous year, with the rapid growth of Robinhood Gold providing the company with a stable source of income.



Meanwhile, RobinHood is actively pursuing acquisitions in the cryptocurrency space. In 2024, it announced a $2 billion acquisition of the long-standing European cryptocurrency exchange Bitstamp. Additionally, Canada's largest cryptocurrency CEX, WonderFi, which recently went public on the Toronto Stock Exchange, also announced its integration with RobinHood Crypto. After obtaining virtual asset licenses in the UK, Canada, Singapore, and other markets, RobinHood has taken a proactive approach in the compliant cryptocurrency trading market.



Furthermore, an increasing number of brokerage firms are exploring the same path. Futu Securities, Tiger Brokers, and others are also dipping their toes into cryptocurrency trading, with some having applied for or obtained the VA license from the Hong Kong SFC. Although their user bases are currently small, traditional brokerages have a natural advantage in user trust, regulatory licenses, and low fee structures. This could pose a threat to native cryptocurrency platforms in the future.



User Data Breach: Is Coinbase Still Secure?


In April 2025, security researchers discovered that some Coinbase user data was leaked on the dark web. While the platform initially responded by attributing it to a "technical misinformation," it still raised concerns among users regarding its security and privacy protection. Just two days before Dow Jones Indexes announced Coinbase's addition to the S&P 500 Index, on May 11, 2025, Coinbase received an email from an unknown threat actor claiming to have obtained customer account information and internal documents, demanding a $20 million ransom to keep the data private. Subsequent investigations confirmed the data breach.


Cybercriminals obtained the data by bribing overseas customer service agents and support staff, mainly in "non-U.S. regions such as India." These agents abused their access to Coinbase's internal customer support system and stole customer data. As early as February this year, blockchain detective ZachXBT revealed on X platform that between December 2024 and January 2025, Coinbase users lost over $65 million to social engineering scams, with the actual amount potentially higher.


Among the victims was a well-known figure, 67-year-old Ed Suman, an established artist in the art world for nearly two decades, having been involved in the creation of artworks such as Jeff Koons' "Balloon Dog" sculpture. Earlier this year, he fell victim to an impersonation scam involving fake Coinbase customer support, resulting in a loss of over $2 million in cryptocurrency. ZachXBT critiqued Coinbase for its inadequate handling of such scams, noting that other major exchanges have not faced similar issues and recommending Coinbase to enhance its security measures.


Amidst a series of ongoing social engineering incidents, although there has not been any impact on user assets at the technical level so far, it has raised concerns among many retail and institutional investors. Especially institutions holding massive assets on Coinbase. Just considering the U.S. BTC ETF institutions, as of mid-May 2025, they collectively hold nearly 840,000 BTC, and 75% of these are custodied by Coinbase. If we price BTC at $100,000, this amount reaches a staggering $63 billion, which is equivalent to the nominal GDP of two Iceland in the year 2024.

In addition, Coinbase Custody also serves over 300 institutional clients, including hedge funds, family offices, pension funds, and endowments. As of the Q1 2025 financial report, Coinbase's total assets under management (including institutional and retail clients) reached $404 billion. The specific amount of institutional custodied assets was not explicitly disclosed in the latest report, but it should still be over 50% based on the Q4 2024 report.

Once this security barrier is breached, not only could the rate of user attrition far exceed expectations, but more importantly, institutional trust in it would undermine the foundation of its business. Therefore, after a hacking event, Coinbase's stock price plummeted significantly.


CEXs are All in Self-Rescue Mode


Facing a decline in spot trading fee revenue, Coinbase is also accelerating its transformation, attempting to find growth opportunities in derivatives and emerging assets. Coinbase acquired a stake in the options platform Deribit at the end of 2024 and announced the official launch of perpetual contract products in 2025. This acquisition fills in Coinbase's gap in options trading and its relatively small global market share.



Deribit has a strong presence in non-U.S. markets, especially in Asia and Europe. The acquisition has enabled Coinbase to gain a dominant position in bitcoin and ethereum options trading on Deribit, accounting for approximately 80% of the global options trading volume, with daily trading volume remaining above $2 billion.


Meanwhile, 80-90% of Deribit's customer base consists of institutional investors, with their professionalism and liquidity in the Bitcoin and Ethereum options market highly favored by institutions. Coinbase's compliance advantage, coupled with its already robust institutional ecosystem, makes it even more suitable. By using institutions as an entry point, it can face the squeeze from giants like Binance and OKX in the derivatives market.



Facing a similar dilemma is Kraken, which is attempting to replicate Binance Futures' model in non-U.S. markets. Since the derivatives market relies more on professional users, fee rates are relatively higher and stickiness is stronger, making it a significant source of revenue for exchanges. In the first half of 2025, Kraken completed the acquisition of TradeStation Crypto and a futures exchange, aiming to build a complete derivatives trading ecosystem to hedge the risk of declining spot transaction fee income.


With the surge of Memecoin in 2024, Binance, OKX, and various CEX platforms began massively listing small-market-cap, highly volatile tokens to activate active trading users. Due to the wealth effect and trading activity of Memecoins, Coinbase was also forced to join the battle, successively listing popular tokens from the Solana ecosystem such as BOOK OF MEME and Dogwifhat. Although these coins are controversial, they are frequently traded, with fee rates several times higher than mainstream coins, serving as a "blood-boosting" method for spot trading.


However, due to its status as a publicly traded company, this practice is a riskier endeavor for Coinbase. Even in the current crypto-friendly environment, the SEC is still investigating whether tokens like SOL, ADA, and SAND constitute securities.


In addition to the forced transformation strategies carried out by the aforementioned CEXs, they are also starting to lay out RWAs and the most talked-about stablecoin payment fields, such as the PYUSD launched through a collaboration between Coinbase and Paypal, Coinbase's support for the Euro stablecoin EURC by Circle that complies with EU MiCA regulatory requirements, or the USD1 launched through a collaboration between Binance and WIFL. In the increasingly crowded trading field, many CEXs have shifted their focus from just the trading market to the application field.


The golden age of transaction fees has quietly ended, and the second half of the crypto exchange platform game has silently begun.
