Original Article Title: Why dTAO is broken

Editor's Note: Bittensor's dTAO mechanism was originally designed to distribute TAO release more fairly, but it exposed problems within just one month of launch. The SN28 subnet exploited a mechanism vulnerability, driving TAO release into meme coin hype, ultimately being intervened by foundation centralization. As decentralization progresses, similar events may be unstoppable, turning Bittensor into a generalized incentive network rather than an AI project. The core issue lies in the lack of a unified goal.

The following is the original content (reorganized for better readability):

Out of Control dTAO Mechanism? Bittensor is Derailing from the AI Track

I am someone who has zero resistance to novel tokenomics. Watching crypto protocols continuously adjust their incentive mechanisms can sometimes seem smart—until they inevitably run into issues, which makes the process itself quite fascinating. So when Bittensor launched the dynamic $TAO (dTAO) system on Valentine's Day (was this @const_reborn's Valentine's gift?), I was immediately drawn in.

The idea was simple: to provide a new, more "fair" way of distributing TAO release, allowing various subnets to more reasonably receive TAO.

However, in less than a month, problems emerged. It turns out that a design that looks reasonable may not necessarily survive in a free market.

dTAO's Operating Mechanism

A quick review of dTAO's operation:

1. Each subnet has its own subnet token ($SN), which exists as a TAO-SN-based UniV2-type native liquidity pool (LP). However, the "staking" of TAO to receive SN is essentially the same as "swapping" TAO for SN. The only difference is: you cannot add additional liquidity to the pool or directly trade between different SN tokens (e.g., SN1 → SN2), but you can indirectly swap through TAO (SN1 → TAO → SN2).

2. TAO release is distributed based on each subnet's SN token price. They use a moving average price to smooth out price fluctuations and prevent price manipulation.

3. The supply of SN tokens is also very high, with a total supply cap of 21 million, similar to TAO and BTC. A portion of it goes into the TAO-SN liquidity pool, while the rest is allocated to the stakeholders of the subnet (miners, validators, subnet owners).

4. The amount of SN tokens entering the TAO-SN liquidity pool depends on how much SN is needed to 'balance' the entry of TAO into the pool, ensuring that the price of SN remains stable in terms of TAO valuation and increasing liquidity at the same time.

5. However, if the calculated amount of SN that the subnet receives exceeds its maximum release amount (based on the SN release curve), the SN release will be capped, leading to an increase in the price of SN in terms of TAO valuation.

Core Assumption of the dTAO Mechanism

Point (2) of the dTAO mechanism is based on a core assumption: a subnet with a higher market value creates more value for the Bittensor network and should therefore receive a larger TAO release.

However, the reality is that in the crypto market, the highest-priced tokens are often those that receive the most attention, hype, strongest marketing, and even have Ponzi-like characteristics. That's why the valuations of L1 chains and meme coins are always relatively high.

The intention behind the mechanism design is good because it assumes that subnets truly creating value will buy back SN tokens through generating revenue, driving up the SN price, and thus receiving more TAO release. But I find this logic a bit naive.

Meme Coin Subnet & Collapsing Tokenomics

Prior to the launch of dTAO, I had discussions with several crypto analysts about the apparent flaws in the dTAO tokenomics model – high market cap ≠ high revenue, nor does it equate to truly creating more value.

However, I didn't expect this theory to be validated by the market so quickly. The operation of a free market is always full of surprises.

Right before the dTAO upgrade, an anonymous user took over Subnet 281 and turned it directly into a meme coin subnet, naming it the 'TAO Accumulation Corporation,' abbreviated as the 'LOL-subnet.' This clearly had nothing to do with AI.

On its (now deleted) GitHub page, it once stated... No mining needed, just holding—completely turned into a Ponzi scheme.

In the LOL-subnet (Subnet 281), miners do not need to run any code, and the validator scoring mechanism is entirely based on the amount of subnet tokens held by the miner. The more SN28 tokens held, the more TAO is released.

In reality, the following occurred: Speculators buy SN28 tokens → SN28 price increases, SN28 price increase → more TAO released, if TAO release exceeds the subnet's token release limit → SN28 price continues to rise, released SN28 tokens are distributed to "miners" based on their holding proportion → the more SN28 held, the more received, in order to get more TAO, more people buy SN28 → higher price → Ponzi cycle continues.

Eventually, the TAO release officially flowed into... a meme coin! At one point, SN28 even became the 7th-ranked subnet in the Bittensor ecosystem.

Why didn't SN28 completely take over Bittensor? Centralization stepped in and saved Bittensor.

During the rapid expansion of SN28, the Opentensor Foundation directly used their root stake to run custom validator code, encouraging everyone to sell SN28. Ultimately, SN28 plummeted by 98% in a few hours and was completely liquidated.

After the Opentensor Foundation took action, SN28 crashed by 98%.

Essentially, the foundation acted as a centralized entity, preventing the free market from operating under the dTAO mechanism. However, they were able to do so because we are currently in a transitional period—the TAO release mechanism is gradually transitioning from the old model to the dTAO mechanism.

Old TAO Release Mechanism & Transition to dTAO

Under the old mechanism, the top 64 validators with the most TAO staked in SN0 ("Root Subnet") could vote to determine where TAO release goes.

However, this mechanism also suffered from significant incentive issues, especially with large validators (such as Opentensor Foundation, DCG Yuma, Dao5, Polychain, etc.) holding too much power.

For example, potential conflicts of interest include:

They may prioritize allocating TAO to their own investments or incubated subnets.

They may direct TAO issuance to their own running validators and subnets eligible for TAO rewards.

These issues have long existed, and while dTAO was intended to address this centralization problem, the SN28 incident demonstrated that the new mechanism still has significant flaws.

Moving towards decentralization is the right direction, but risks remain

Breaking away from the old mechanism is indeed a step in the right direction towards decentralization. Although this may mean the team will lose some control over TAO issuance, I still commend their choice of a more decentralized reward mechanism.

However, at the time of the SN28 incident, the dTAO mechanism had only just gone live for a week, and SN0 (root subnet) still controlled about 95% of the TAO issuance (as shown by the blue line in the chart below), allowing the Opentensor Foundation to intervene swiftly to prevent further fund inflation.

But the issue is:

· About a year later, SN0's power will gradually decrease to around 20%, at which point it will no longer be able to directly control most of the TAO issuance.

· If there is a future occurrence similar to SN28, it is very likely that no one will be able to intervene through SN0 anymore.

In this scenario, Bittensor may no longer be a "decentralized AI" project and could become a full-fledged meme coin incentive network.

Bittensor is still in the transition period of its issuance mechanism, with control shifting from the old mechanism (SN0 or "root prop") to the new mechanism (dTAO or "alpha prop").

More than just a meme coin, Bittensor could become a generalized incentive network

Even if we assume that in a bear market environment, people will not rush into meme coins, there is still a high probability that Bittensor will become a completely AI-unrelated "generalized incentive network."

For example: If someone launches a decentralized subnet for Bitcoin mining (this concept is not new), it can incentivize a more efficient BTC mining method, then use the mined BTC to continuously repurchase SN tokens, thereby gaining TAO emission.

If this pattern holds, TAO will transition from a decentralized AI project to a broad incentive project. TAO emission will no longer be used to drive AI development but will instead become a subsidy mechanism for various operational costs (OpEx).

Technically, this is not inherently wrong because the Yuma consensus mechanism is designed to achieve consensus on "subjective" work and is not necessarily limited to AI. However, without a clear goal, the entire network may become... meaningless.

Epilogue: Cracks in the dTAO Mechanism Are Already Showing

The dTAO mechanism has only been live for 1 month, and issues have already surfaced.

According to the incentive logic of a free market, without centralizing forces intervening, Bittensor may no longer be an AI project but rather an "attention network" dominated by meme coin subnets or transform into a broad incentive network where various enterprises use TAO emission subsidies for operational costs without driving the development of the Bittensor ecosystem.

I believe Bittensor needs a true "objective function" to align all subnets in the same direction. However, the issue lies in the difficulty of defining an absolute goal in the AI field (AGI?). As we have seen, even the LLM evaluation framework is challenging to make completely fair... That is also why the Yuma consensus mechanism was initially designed to achieve consensus on "subjective" work.

"Tell me the incentive mechanism, and I can tell you the outcome." Peace!

$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.
