The Blockchain Trilemma

The Blockchain Trilemma


Blockchain is a technology that has emerged partly to provide greater freedom and fluidity in managing money. Moreover, it acts as a technology that accelerates the exchange of information and valuable assets between participants in a process, eliminating the dependence on intermediaries.

As for the characteristics of Blockchain technology, we could highlight three:

  • Immutable and shared: It only allows information to be added. Therefore, it is a record of information that cannot be modified. In addition, an identical copy of the information is distributed to all participants.

  • Decentralised and scalable: There is no central operator, which makes it highly reliable as there is no single point of failure or attack. In addition, participants are organised by common consensus to validate stored information. Moreover, it has the ability to grow naturally, so the platform’s power can grow progressively and based on demand.

  • Secure and robust: blockchain technology uses cryptography to store information, which makes it immune to fraud. It is also worth mentioning that it draws on increased computational power by combining the computing power of all connected computers.

What is this trilemma about?

However, there is a problem linked to this technology: the so-called Blockchain Trilemma, a term coined by Vitalik Buterin. It consists of any developer having to sacrifice one of these characteristics to make room for the other two:




Scalability:

In the blockchain, scalability refers to how large a network can expand in the future while maintaining the current transaction speed and performance level. When scalability and decentralisation operate together, security suffers because security prevents innovations that would allow the decentralised network to scale. This occurs because decentralised networks are difficult to scale since they require much effort to operate.

Security:

Blockchain networks are not entirely secure, as a hacker can modify a blockchain and manipulate transactions if he gains control of more than half of the network (51%). Therefore, the more nodes there are in a blockchain, the more secure it is.




Decentralisation

Most protocols use Proof of Work (PoW) to achieve greater decentralisation. This means that much energy is needed to operate, making transactions per second very low and, therefore, more difficult to scale.

Solutions to the Blockchain Trilemma





In trying to solve this problem, some projects do so at layer 1, while others seek to address their weaknesses through a layer 2 solution.

Advertisement


Layer 1:


Advertisement

Layer 1 networks refer to blockchains, while layer 2 protocols refer to a third party’s integration of a layer 1 blockchain. For example, Bitcoin, Litecoin and Ethereum are layer 1 blockchains.


Layer 1 scalability solutions augment the base layer of the protocol itself to improve its scalability. They change the rules of the protocol to increase the speed and capacity to process transactions while adapting to process more data and serve more users.

For example, a layer 1 scalability solution could increase the amount of data contained in each block on the blockchain.

An example of a layer 1 enhancement is sharding, which in a nutshell, consists of dividing the state of the entire network into different data sets called shards. In this way, nodes have to maintain less of the network, which makes their work more manageable.

These network shards are processed at the same time in parallel, allowing sequential work. Individual shards provide evidence to the main blockchain and interact with each other to share addresses, balances and other data using inter-shard communication protocols.


Layer 2:

Layer 2 solutions refer to a network that operates on top of a blockchain to improve its scalability and efficiency. This type of solution passes part of the transaction load to an adjacent system that handles most of the network processing and reports back to the main blockchain upon completion of the results. In this way, the main blockchain is decongested.

For example, the Lightning Network is a layer 2 solution created to improve the transaction speeds of the Bitcoin network.

Other layers 2 examples are:


– Nested blockchains

Advertisement


Nested blockchains are one blockchain built on top of another. A nested blockchain generally includes a primary blockchain that sets the parameters and a secondary network where executions occur. 

Advertisement


– Sidechains


Advertisement

These are a sidechain associated with the primary blockchain via a bidirectional connection. The purpose of sidechains is focused on managing a large number of transactions, as a sidechain could support the primary chain in validating different transactions in blockchain networks. In this way, the primary chain finds enough time to solve security problems.


– State Channels

Advertisement


State channels facilitate the option of transacting without regard to the primary chains, allowing miners to spend less time on verification.

Advertisement


State channels do not rely on verifying transactions at layer 1 of the blockchain and use smart contracts to do so. Once a transaction is completed, state channels ensure that the resulting state is stored in the primary layer. 


Advertisement

– Rollups


Rollups are layer 2 protocols that can perform computations outside the primary chain. In addition, rollups can help manage transactions without any interference at the primary layer. As a result, rollups guarantee the higher performance of blockchain transactions while ensuring cost reduction. 

Advertisement




Conclusions


Advertisement

A blockchain should have security, decentralisation and scalability. However, achieving a perfect balance in these three factors is difficult, which causes the Blockchain Trilemma: trying to improve scalability makes security and decentralisation suffer. On the other hand, improving the latter causes scalability to suffer.


The idea is to look for a second-layer solution that gets this problem out of the way. In this way, we can get scalability in these solutions while the first layer takes care of decentralisation and security.

Crypto Markets Struggle as BTC Slips Below $64K

Published

on

the-defiant

BTC failed to hold key support levels, dragging the wider crypto market lower.

Cryptocurrency markets are under pressure again, with traders reacting to broader AI-linked fears, lingering macro uncertainty and signs of waning institutional demand. Today, Feb. 24, total crypto market capitalization slipped 2.5%, currently hovering around $2.27 trillion.

Bitcoin (BTC) slid from about $66,000 on Monday morning, Feb. 23, to near $63,700 at press time, marking a 3% daily decline. BTC’s weekly losses are around 6%.

Ethereum (ETH) tracked BTC’s move, falling 3% to $1,840, and down 5.4% on the week.

Among the rest of the top-10 assets, most are seeing mild to moderate losses today. XRP is down 1.7% to $1.35, BNB lost 3.6% to about $585, and Solana (SOL) declined 3% to $77.

Figure Heloc (FIGR_HELOC) was the only top-10 large-cap in the green this morning, up 1.5%.

Oversold

Alex Thorn, head of firmwide research at Galaxy Digital, noted in an X post today that BTC is approaching all-time oversold territory, with weekly RSI readings lower than any moment outside the deepest bear markets, citing November-December 2018 and mid-2022 as rare comparable periods.

Wintermute analysts highlighted in another X post today that Bitcoin has repeatedly failed to break through the $70,000 mark in the past two weeks, while ETH dipped below the psychologically important $1,900 mark.

“Multiple times over the past decade, growth scares have triggered rotations that ultimately reversed as risk appetite returned and the market found its way back to momentum,” the analysts noted.

They added that thin liquidity with derivatives signals a lack of directional conviction. Some selective interest in altcoins from high-net-worth investors briefly emerged mid-week but quickly faded.

Big Movers and Liquidations

Looking at the top-100 assets by market cap, PIPPIN gained the most, up 6.6% to $0.77 on the day, while Monero (XMR) rose 3.4% to $325.

On the downside, Bitcoin Cash (BCH) led losses at 11% to $475.40, followed by NEXO, down 5.5% to $0.80.

According to CoinGlass data, around 137,000 traders were liquidated over the past 24 hours, with total losses of $412.9 million, where BTC accounted for $156.3 million and ETH for $131.7 million, while other altcoins accounted for $22.1 million.

ETFs and Macro Conditions

Spot Bitcoin ETFs saw $203.8 million in outflows on Monday, bringing cumulative assets to $80.7 billion. Ethereum ETFs recorded $49.4 million in outflows, with total net assets now at $10.4 billion, per SoSoValue data.

Macro conditions still feel shaky. Shares of IBM plunged about 13% on Monday, Feb. 23 — the stock’s steepest drop in more than 25 years. The selloff came after Anthropic said its Claude Code tool can automate COBOL modernization, the old-school language that still rakes in serious revenue for IBM.

Adding to the nervous mood, analysts at Citrini Research warned in a Feb. 22 note that rapid AI adoption could displace large numbers of white‑collar jobs, squeeze consumer spending, and put pressure on both financial and tech sectors.

In comments to investors on Monday, JPMorgan CEO Jamie Dimon drew comparisons between current credit and risk dynamics and those seen in the run‑up to the 2008 financial crisis, fueling more caution among investors.

GCC Leaders Fast-Track GenAI Adoption Across Tax, Finance and Legal Sectors

Published

on

Crypto Breaking News

Editor’s note: The GCC region is moving quickly from experimenting with Generative AI to embedding it across core business functions. Deloitte’s newly released survey of tax, finance and legal leaders shows a clear acceleration in GenAI adoption, driven by a demand for smarter research, decision support and quality assurance. As regional companies navigate data privacy, governance and implementation roadmaps, this editorial note highlights momentum and the remaining gaps that organizations must address to translate ambition into measurable outcomes.

Key points

  • GenAI adoption is accelerating across tax, finance and legal functions in the GCC.
  • Non-adoption fell from 52% in 2024 to 29% in 2025, with participation rising 47% year over year.
  • Priorities have shifted toward research and analysis (41%) and quality improvement (38%).
  • Only 18% are piloting GenAI, 9% are scaling, and 10% have enterprise-wide AI strategies and governance in place; 63% remain in pre-implementation.
  • Automation remains a major opportunity, with 53% prioritizing automation; emphasis on research and data analysis (41%).

Why this matters

GenAI adoption in the GCC signals a shift from experimentation to strategic capability across tax, finance and legal functions. The findings underscore the importance of governance, robust operating models and workforce readiness to translate momentum into measurable business value and trusted, scalable deployment across enterprises. With rising confidence in AI’s long-term potential, organizations must balance speed with quality, risk controls and responsible governance to sustain momentum.

What to watch next

  • Move from pilots to enterprise-wide AI strategies and governance frameworks.
  • Strengthen governance, operating models and adoption roadmaps.
  • Invest in data quality and capability development for deeper analytics.
  • Monitor automation opportunities and balance between speed and quality.

GCC Leaders Accelerate GenAI Adoption in Tax, Finance and Legal Functions

 A new Deloitte survey reveals rapid uptake across the region, alongside growing gaps in governance, strategy and implementation.

Dubai, UAE – 24 February, 2026: A new regional survey by Deloitte’s Tax & Legal business shows that organizations across the GCC are rapidly adopting Generative AI (GenAI) in tax, finance, and legal functions – but many are still struggling to move from experimentation to enterprise-wide impact.

Based on insights from senior tax and finance leaders across Saudi Arabia, the UAE, Qatar, and Kuwait, the survey shows rapid acceleration in GenAI adoption across the GCC. Non-adoption fell sharply from 52% in 2024 to 29% in 2025, while survey participation rose 47% year over year. The survey results indicate that GenAI has become a mainstream strategic priority for regional leadership teams.

While early adoption focused on basic productivity tasks such as email drafting, priorities have moved toward research and analysis (41%) and accuracy and quality improvement (38%). This reflects a transition from efficiency-led experimentation to more strategic value creation. At the same time, 93% of respondents expect AI to have a significant impact on their organizations, highlighting strong regional confidence in the technology’s long-term potential.

Yet despite this momentum, execution remains a key challenge. While 18% of organizations are actively piloting GenAI use cases, only 9% have begun scaling solutions, and just 10% report having enterprise-wide AI strategies and governance frameworks in place. More than 63% remain in pre-implementation stages, underscoring the need for clearer operating models, stronger governance, and structured adoption roadmaps to translate ambition into measurable outcomes.

Automation continues to be a major opportunity area, with 53% of respondents prioritizing automation, particularly in data validation and data reconciliation. However, leaders are increasingly emphasizing quality over speed, with research and data analysis accounting for 41% of current GenAI applications, signalling demand for deeper analytical support rather than simple task automation.

Implementation approaches vary widely across the region. While some organizations are adopting subscription-based or hybrid models, 38% say they are still exploring how to operationalize GenAI, reinforcing the need for advisory support to bridge strategy and execution.

Reflecting on the regional landscape, Muhammad Bahemia, Middle East Tax Leader at Deloitte, said: “The pace of Generative AI adoption across the GCC reflects a region that is both ambitious and pragmatic. Leaders clearly recognize the technology’s potential, but many are now confronting the harder question of how to scale it responsibly. Through our work across tax, finance, and legal functions, Deloitte is helping organizations translate innovation into disciplined execution; strengthening governance, building capabilities, and embedding AI in ways that deliver measurable value and enduring trust.”

Further commenting on the findings, Mohamed Serokh, Partner, at Deloitte Middle East, said: “What we’re seeing across the GCC is a clear shift from curiosity to action. Leaders recognize GenAI’s potential to fundamentally reshape tax, finance, and legal functions, particularly in research, analysis, and quality improvement. However, our survey also shows that many organizations are still navigating how to move from pilots to scalable impact. Success will depend on strong governance, capability development, and a disciplined approach to implementation.”

The survey concludes that while experimentation is widespread, the next phase for GCC organizations must focus on structured execution. Prioritizing high-impact use cases in research and tax analysis, strengthening governance frameworks, and investing in workforce readiness to support responsible, scaled adoption.

Fluid Proposes Establishing a Foundation Funded by $3M Annual Grant From DAO

Published

on

the-defiant

If approved, the governance proposal by Instadapp’s COO would establish a non-profit foundation to oversee the DeFi protocol’s code, frontend and trademarks.

Fluid DAO is considering a proposal to transfer all of the DeFi platform’s intellectual property into a Cayman Islands foundation, and to approve a $250,000 monthly grant to fund development and operations.

The proposal was submitted on Monday, Feb. 23, by DMH, the COO of Instadapp, the firm behind Fluid. It calls for the creation of the Fluid Foundation governed by DAO votes, a familiar corporate setup for crypto organizations.

Under the plan, “all Fluid Protocol smart contract code,” front-end interfaces, domains, trademarks and related assets would be transferred to the foundation. Once completed, the assets would “belong to the Foundation — not to any individual, company, or labs entity,” DMH wrote.

The foundation would have no owners and would operate through custodians and directors, according to the proposal. Its sole purpose would be to hold and steward the protocol’s intellectual property on behalf of the DAO.

“The Fluid team acts as custodians of the Foundation — not owners,” the proposal states, with FLUID token holders retaining “ultimate authority” through governance.

Control Stays with DAO

The proposal argues that a legal entity is needed as the protocol, which now has over $1 billion in total value locked (TVL), expands and engages with off-chain counterparties. A foundation structure would allow Fluid to meet “AML, KYC, banking, and regulatory requirements” without altering how token-based governance functions, the proposal argues.

Token holders would also retain the power to change foundation policy or shut it down entirely. The proposal says holders could “in an extreme case, dissolve the Foundation entirely through a governance vote.” DMH further elaborated in a response to a comment on the proposal:

Advertisement

“It is very important to understand that in the legal field, token holders and DAO have no rights; this is why we are creating a legal wrapper that can now have ownership rights over the protocol, and this foundation has no ownership.”

To fund the structure, the DAO is being asked to approve a $250,000 monthly grant, or about $3 million a year from its treasury, which is funded by protocol revenue. The budget would cover engineering, infrastructure, security, business development and general operational costs, according to DMH.

‘Foundation Bears the Legal Costs’

Fluid operates a decentralized lending and borrowing protocol, as well as a swap interface. According to data from DefiLlama, that combination has brought Fluid roughly $1.2 billion in TVL and generated about $1.1 million in revenue in January. In August, the platform saw a record high revenue of $1.52 million. Taking Fluid’s best revenue month yet, the grant would consume around 16% of that monthly revenue.

If approved, legal work to transfer the IP is expected to be completed by mid-2026, with Cayman Islands counsel handling the process. The team also plans to move ownership of all EVM deployments under direct DAO governance.

Some raised concerns about liability if the foundation were sued. In response, DMH said that “if the foundation gets sued, the foundation itself bears the legal costs and any liability.”

Over the past 24 hours, FLUID slid 6% from around $2 to $1.88, but has since recovered to $1.96.

The Defiant reached out to Instadapp for comments on the proposal, but hasn’t heard back by press time.

Late last year, a fee-related dispute between the two main entities behind Aave — Aave Labs and Aave DAO — turned into a broader debate on how crypto organizations should be structured.

Tom Lee’s ETH losses at Bitmine exceed FTX customer losses

Tom Lee’s ETH losses at Bitmine exceed FTX customer losses

Tom Lee, founder of Fundstrat and Chairman of ether (ETH) treasury company Bitmine Immersion Technologies, has lost more on ETH using other people’s money than the $8 billion worth of losses suffered by FTX customers.

With 4,422,659 ETH purchased at an average $3,850 apiece, Lee’s company raised capital to buy the asset at over $2,000 more per coin than today’s price.

As a result, he’s lost $8.8 billion of his company’s assets.

At time of writing, ETH is trading at $1,843, down 60% over the past six months alone. Unfortunately, Bitmine Immersion has been buying tons of ETH over that bearish period — increasing losses for its investors at an alarming rate. 

Over the past six months, as ETH was declining 60%, Bitmine Immersion bought an extra 2,708,760 ETH. 

Those progressively disastrous additions increased the company’s losses from $4.8 billion to $8.8 billion.

Bitmine Immersion lost $8.8 billion by buying ETH

It’s not particularly remarkable for digital asset treasury (DAT) companies to have declined in value.

The Wall Street fad, which peaked in early summer 2025, was to overpay for leverage in the hope that the mania would increase to even more exuberant heights, or that the company could convince bond investors or other capital allocators to offer it even more leverage.

In the distant future, all DATs focused on the ultimately limited supply of bitcoin (BTC) or ETH as another reason to invest in these leveraged acquisition strategies, even though their efforts to corner the market usually fizzled within single digit percentages of the outstanding supply of those assets.

What started as modest premiums of a few percentage points quickly ballooned into stock debuts rallying to 23x the value of their crypto holdings.

That once-23x overvalued stock, like many similar treasury stocks, fell 98% by November from its May peak, and is now down over 99%.

Bitmine Immersion is down 88% from its July 2025 high. It’s lost over $600 million on its ETH holdings in the past week.

Within five months of its June 3, 2025 peak, Lee’s company had shed 80% of its stock value. By February 5 of this year, Lee’s ETH treasury had lost $8 billion for investors, and that loss extended to as much as $9 billion intraday this morning.

Coinbase Opens Commission-Free Stock and ETF Trading to All US Users

Coinbase has opened stock and exchange-traded fund trading to all US users, allowing customers to buy and sell equities alongside crypto within the same app on a 24/5 basis. The rollout includes commission-free trading, fractional shares, and instant funding with USD or USDC. 

According to a company post on Tuesday, thousands of stocks are available to trade 24 hours a day, five days a week, with approximately 6,000 securities currently supported and plans to expand that number in the coming weeks.

Coinbase said it aims to introduce stock perpetual futures for non-US users through Coinbase Bermuda Ltd., subject to regulatory approval, and said it intends to offer tokenized equities in the future.

Today’s announcement comes on the heels of Coinbase expanding its prediction markets offering to all 50 US states last month through a partnership with Kalshi, allowing users to trade contracts tied to real-world events across sports, politics and culture.

Tokenized equities gain traction from crypto platforms to Wall Street

Tokenized equities, blockchain-based representations of traditional shares, have emerged as a major theme in crypto over the past year.

In June, more than 60 tokenized stocks became available on crypto exchanges Kraken and Bybit, as well as on Solana-based DeFi platforms. The rollout, led by Backed Finance through its xStocks product, gave users blockchain-based exposure to major companies including Apple, Amazon, Tesla, Nvidia, Meta, Coinbase and Robinhood.

In October, fintech Robinhood expanded its own tokenization program on the Arbitrum blockchain, adding 80 new stock tokens and bringing its total to 493 tokenized assets.

While crypto-native and fintech platforms have led recent rollouts, interest in tokenized equities now extends to some of the world’s largest exchanges.

In September, Nasdaq filed with the US Securities and Exchange Commission (SEC) seeking approval to list tokenized equities, and in November, the exchange’s head of digital assets strategy, Matt Savarese, told CNBC that securing SEC approval to list tokenized versions of exchange-listed stocks is a top priority for the company.

In January, the New York Stock Exchange and its parent company, Intercontinental Exchange, announced plans to develop a platform for trading tokenized stocks and ETFs. The proposed system would support 24/7 trading and instant settlement by combining NYSE’s Pillar matching engine with blockchain-based post-trade infrastructure.

Coinbase also today announced a partnership with Yahoo Finance to enable users to move from researching an asset on Yahoo Finance to executing a trade on Coinbase with one click. Yahoo Finance will incorporate real-time information from Coinbase for asset discovery and tracking.

The US-based exchange said Coinbase One members can earn rewards on USDC (USDC) balances used for trading, and Yahoo Finance users will be offered a one-month trial of Coinbase One Basic as part of the partnership.
