Setting aside market value and hype, what exactly determines the long-term success of a blockchain? Gavin Wood, co-founder of Ethereum, proponent of the Web3 concept, and creator of Polkadot, shared his evaluation of blockchain's five key criteria.

In an interview with Forbes, Gavin Wood, a visionary in the crypto industry, explained which factors can make blockchain projects successful and which can cause them to fail. He also shared some useful assessment criteria and provided direct analysis of the most popular blockchain projects today.

His analytical approach helps us better understand the price fluctuations of leading cryptocurrencies in the blockchain space. For example, why did ETH's market cap drop from its 2021 peak of $575 billion to its current $394 billion? Why did SOL's market cap break its all-time high, reaching $115 billion, while Polkadot's DOT (launched around the same time) dropped to $9 billion? Wood not only observed the numerical changes but also identified the key reasons behind the influences driving these changes.

Gavin Wood's Five Blockchain Evaluation Criteria

Currently, there are hundreds of blockchains, each with its unique technology, use cases, and adoption. To help us identify truly promising blockchains, Gavin Wood has outlined five fundamental criteria for assessing them.

· Resilience: The cornerstone of Web3, resilience combines cryptography, decentralization, and game theory to protect the blockchain from attacks and ensure its long-term stability.

· Performance: Performance not only refers to scalability but also measures a network's efficiency in processing and completing tasks.

· Generality: Blockchain's support for multiple applications and programmability.

· Accessibility: The ease with which users, developers, applications, and bots interact with the network.

· Consistency: The ability of a system to maintain fast and consistent communication within its network.

Resilience: Uncompromisable Standard

While blockchain can emphasize different characteristics, there is one standard that absolutely cannot be compromised, and that is decentralization and resilience. This standard is difficult to assess, requires long-term attention, but is the most important.

Gavin Wood stated: "Blockchains that overlook decentralization and resilience should not be called Web3."

He continued: "For example, we see that on Ethereum's L2 networks, there is a fixed set of validators managed by a specific company, right? This is clearly not a feature of Web3."

Evaluating a blockchain's resilience is usually summarized as assessing the degree of its decentralization. Wood proposed several questions for evaluation:

Who makes protocol decisions?

Does the governance structure have a clear or low-barrier-to-entry way in?

And then there's the Nakamoto coefficient, which measures the number of participants needed to disrupt the network.

Finally, Wood also mentioned a more overarching issue, such as whether there is a single entity that can dominate the entire project's direction and "fully control the ecosystem, suppressing other voices and viewpoints."

Gavin is satisfied with the decentralization of Polkadot and states that its Nakamoto coefficient is quite high. According to Nakaflow's data, Polkadot currently has a Nakamoto coefficient of 149, which means that at least 149 independent validators need to come together to disrupt this network. In comparison, the scores of some other major blockchains are much lower, such as Solana with a score of 19 and Ethereum with just 2.

However, the barrier to entry remains a concern.

Saudi Arabia's KAUST research scientist Maurantonio Caprolu, who has co-authored multiple papers on Polkadot with Professor Roberto Di Pietro, describes the high barrier to entry issue.

"Until 2022, to become an active validator, an average stake of around 1.8 million DOT was needed (equivalent to approximately $32 million at the time). Even now, this minimum staking requirement remains high, actually favoring institutional players who can afford the significant DOT token cost to participate."

From Gavin's defined resilience standard, Ethereum's weaknesses become apparent. Ethereum is often criticized for the significant influence of Vitalik Buterin. Particularly, a recent post of his on X—"The person deciding the new EF (Ethereum Foundation) leadership team is me"—has escalated this controversy further.

One might ask: Given Gavin Wood's significant role in Polkadot, does Polkadot also face the risk of a narrative dominated by Gavin? Wood acknowledges the weight of his name, but he emphasizes that Polkadot's governance is community-driven. He cites some successful community-led proposals, such as reducing DOT's inflation rate, as examples, demonstrating Polkadot's decentralized decision-making process.

The Polkassembly governance platform further enhances community participation and will launch an OpenGov-compliant framework in 2023. Caprolu and his team believe that OpenGov can "enhance inclusivity and reduce centralization of power." However, researchers point out: "Since this system is still in its early stages, more time and data are needed to verify whether OpenGov can successfully alleviate the centralization tendencies observed in our governance 1.0 (i.e., the governance model before Polkadot)."

Performance: What Comes at What Price?

Various blockchains have taken different approaches to enhancing performance, but they all face the common challenge of finding a balance between performance improvement, decentralization, and consistency.

Take Ethereum as an example. Wood explained, "Initially, they planned to use sharding technology to shard the EVM into the network. However, they later abandoned this plan and instead chose to support L2 solutions. In reality, they didn't do anything and just let others build chains, ensuring the security of these chains through Ethereum." This approach led to a lack of consistency, even impacting security. Wood believes that "after Ethereum is combined with L2, it is not actually the real Ethereum anymore because L2 does not provide the same level of security."

Furthermore, Gavin believes that Solana sacrificed decentralization.

"Solana's strategy is to make its validators more powerful and ensure good connectivity among these validators. To achieve this goal, Solana reduced the number of validators. Because to improve connectivity between two validators, it usually requires reducing the number of participating validators. The result of this approach is that Solana's Nakamoto coefficient has decreased because fewer validators mean fewer participants can control the network, thus reducing the level of decentralization."

Gavin Wood referred to Solana as "a highly synchronous scaling strategy," where its speed is limited by the processing power of a single machine and the speed of syncing data. Although this approach can achieve rapid scaling in the early stages, it will ultimately be bottlenecked by hardware and network limitations.

For Wood, "many other proof-of-stake chains are similar. They don't have a consistent scaling strategy. To handle more data, they simply reduce the number of validators and increase speed."

Polkadot's approach is different from Solana's; it achieves network scaling and optimization by adding more validators. Specifically, Polkadot enhances decentralization by increasing the number of validators rather than decreasing them. With more validators participating, Polkadot not only maintains decentralization but also allows the network to operate faster. In other words, Polkadot optimizes performance through "scaling" without sacrificing decentralization for speed.

Universality: True Turing Completeness

Gavin Wood defines blockchain universality by measuring the ease with which Web2 applications can transition to Web3. More specifically, he measures universality based on how many different types of computational tasks a blockchain can support and the complexity of these tasks.

Ethereum introduced the concept of Turing completeness, meaning it can execute any computable task. However, as Wood pointed out, Ethereum has not fully realized this. This is because it is subject to gas limits and block size constraints, and computation must fit within these limits, restricting the range of complex problems it can solve.

Polkadot aims to eliminate these constraints through its parachain model. Parachains execute their own logic in a WebAssembly environment, as long as the computation completes within seconds. This setup allows parachains to handle larger datasets. Currently, Ethereum allows about 15 million EVM gas per block, while for Polkadot, this number is equivalent to 18 billion gas.

Nevertheless, Polkadot's generality, like Ethereum, is still quantitative, not qualitative. It extends computational capacity but does not fundamentally change the scope of computation. With the upcoming JAM upgrade, this scenario will change. The JAM upgrade promises to enable "continuations," where computation can pause and resume between blocks.

Soulla Louca, the head of the University of Cyprus Blockchain Initiative, believes that removing the limitation of single-block computation could be a significant breakthrough. She explains:

"While other blockchains have mechanisms for processing complex computations (e.g., layer 2 solutions, optimistic rollups), no other blockchain currently offers a built-in continuations mechanism similar to what JAM proposes. This capability could provide Polkadot with a significant advantage, supporting more complex and general-purpose applications, especially advanced applications like complex financial instruments, large-scale data processing, on-chain AI/ML, and more."

Consistency: Overcoming Barriers

Consistency is a key challenge facing the blockchain ecosystem. Both Ethereum's L2 and Polkadot's parachains encounter difficulties in this area. As Wood described, they operate in isolated environments, and cross-chain interactions are often slow, expensive, and potentially insecure unless a co-ordination system is introduced. However, such a system also poses its own challenges as it requires supercomputing to perform coordination, inevitably leading to centralization.

Wood acknowledged that consensus is not Polkadot's primary focus. Although some integrations and bridging have taken place over the past year, parallel chains still face consistency issues.

This issue was also highlighted by OriginTrail founder Tomaž Levak. His company has developed a DeSci (Decentralized Science) protocol aimed at structuring and connecting real-world data for AI and enterprise applications, running on its own Polkadot parachain. Levak stated that while "the performance and customization capabilities brought by Polkadot's technical design are very unique in meeting demands," he hopes to see "enhanced bridging infrastructure with other blockchain ecosystems."

Accessibility: Usability Testing

In the blockchain space, the general perception is that Polkadot technology is very powerful but hard to understand. However, Wood pointed out that due to upgrades to the XCM (Cross-Chain Message) system and ecosystem wallets, Polkadot's accessibility has significantly improved over the past year. Similarly, Tomaž Levak also stated that OriginTrail's end users "rarely interact directly with the blockchain layer, as a user-friendly interface ensures a smooth experience."

However, despite this, consistency issues still exist, hindering accessibility. Wood stated that JAM will address this issue by providing shared data availability storage, where services can be built to completely hide the consistency issues users face.

In terms of developer engagement, Wood proudly pointed out that Polkadot has had many "serious" full-time developers. In fact, Electric Capital's developer report ranks Polkadot's tech stack third in the crypto space. Currently, Polkadot has 467 full-time developers, second only to Solana (599) and Ethereum (3562). However, Wood believes the actual number is higher, as the 35 teams working on JAM are in a closed-source environment and not included in the report.

Overall, currently, no blockchain has been able to master all five of these benchmarks perfectly. As Gavin Wood stated:

"Some blockchain systems have great performance but lack consistency, like Polkadot. Others, like Ethereum, perform well in terms of consistency but have lower performance. If you look at Solana, it does well in terms of consistency but lacks resilience and decentralization. Therefore, currently you can choose some of these features, but no blockchain can meet all these requirements simultaneously."

The real winners will be those who adapt to change in the blockchain space without compromising on the core principles of Web3. The question is: Which blockchain will be the first to find this balance?

$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.
