Let’s delve into Cardano’s core technologies and the challenges it currently faces.

Cardano’s Unique Proof-of-Stake Mechanism: Ouroboros

One of Cardano’s most significant features is its unique Proof-of-Stake (PoS) consensus algorithm, Ouroboros. It is the world’s first academically peer-reviewed and ‘security-proven’ Proof-of-Stake protocol. It sustainably decentralizes the Cardano network without sacrificing security. This academic rigor significantly contributes to the blockchain’s robustness and stability, helping to identify and resolve potential issues before they become actual problems. Ouroboros addresses the energy inefficiency of Bitcoin’s Proof-of-Work (PoW) mechanism, solidifying its position as an environmentally friendly blockchain.

Layered Architecture and Scalability Solutions

Cardano boasts an architecture composed of two independent layers. One is the Cardano Settlement Layer (CSL), responsible for recording financial transactions, and the other is the Cardano Computation Layer (CCL), which supports the execution of smart contracts and decentralized applications (dApps). This layer separation reduces network load, increasing transaction processing speed and lowering fees.

• Improved Throughput: A public testnet for the Leios upgrade, aiming to improve network throughput by up to 60 times, is scheduled for June 2026.
• Enhanced Privacy: The Midnight mainnet, a privacy-focused sidechain, was already launched at the end of March 2026, with institutions like Google Cloud participating in node operations.
• Other Scalability: Other scalability solutions such as Hydra and Mithril are also under continuous development.

Decentralized Governance and Ecosystem Challenges

Cardano embraces community-driven decentralized governance as a core value, strengthening its treasury system and community decision-making processes through the Voltaire era. Notably, CIP-1694 on-chain governance is fully operational, providing a system where ADA holders can directly vote on protocol changes and more.

However, the Cardano ecosystem has recently faced several challenges. Founder Charles Hoskinson expressed disappointment regarding community support for treasury funding, and indeed, the 2026 Cardano Summit was canceled after its funding proposal was rejected. Hoskinson also warned that more projects might close in the second half of 2026 due to weak market conditions and funding issues. Nevertheless, the recent approval of active cryptocurrency ETFs, including ADA, by the U.S. Securities and Exchange Commission (SEC) suggests increased accessibility for institutional investors.

Cardano has forged its unique path in the blockchain ecosystem based on academically-backed technology and a community-centric philosophy. While currently experiencing market difficulties and internal struggles, Ouroboros, its layered architecture, and continuous development of scalability solutions still demonstrate Cardano’s potential. It remains to be seen whether Cardano will overcome these challenges and prove its value as a true third-generation blockchain.

게시물 Cardano: 3 Key Technologies and Latest Trends Amidst a Bear Market이 솜삽 블로그에 처음 등장했습니다.

The Iranian rial has plummeted to an all-time low, and hyperinflation is shaking the lives of its citizens to their core. A situation where money turns into mere scraps of paper in just a few days is not just a distant story. This crisis, caused by a combination of an unstable international situation and complex economic woes, clearly demonstrates how vulnerable the value of money, which we take for granted, can be.

Iranian Rial Plummets: The Moment Money Becomes Worthless

On April 29, 2026 (local time), the Iranian rial exchange rate hit an all-time low of 1.81 million rials per U.S. dollar. This was a sharp drop of over 15% in just two days. The Iranian economy was directly hit by the collapse of its currency value as demand for dollars surged due to reduced oil exports and foreign currency inflows from the prolonged blockade of the Strait of Hormuz.

The sharp drop in the exchange rate immediately led to price increases. Analysis suggests a high probability of overall price increases for food, medicine, and raw materials. The International Monetary Fund (IMF) projected Iran’s economy to contract by 6.1% this year, with inflation reaching 68.9%. This is a typical sign of hyperinflation, where the purchasing power of money disappears incredibly quickly, beyond just rising prices.

• Exchange Rate Surge: Rial value dropped over 15% in two days, reaching 1.81 million rials per dollar.
• Price Increases: Concerns about overall price increases for essential goods like food and medicine.
• Economic Contraction: IMF projects Iran’s economy to shrink by 6.1% with 68.9% inflation.

South Korea’s Economy: Growth Amidst Instability

While Iran’s situation is extreme, the South Korean economy is not entirely safe either. In 2026, South Korea’s economy is expected to see a moderate recovery of around 2% driven by consumption-led domestic demand. However, structural weaknesses such as lower growth potential than pre-pandemic levels and sensitivity to changes in external conditions persist.

In particular, the won/dollar exchange rate is likely to remain high, above 1,350 won, and its volatility is expected to increase. This could put pressure on households and businesses by increasing import prices. Furthermore, high household debt continues to restrict interest rate cuts. The rapid increase in national debt, despite the government’s expansionary fiscal policy, is also a risk factor that cannot be overlooked.

• Moderate Growth: South Korean economy projected to grow around 2% in 2026.
• High Exchange Rate: Won/dollar exchange rate expected to stabilize above 1,350 won with increased volatility.
• Household Debt Burden: Concerns about restricted interest rate cuts and rising national debt.

Unstable Financial Markets: Protecting Asset Value

Global economic uncertainty remains high. U.S. political events (such as changes in the Fed chair, Supreme Court rulings, and midterm elections) are expected to have an impact throughout 2026, but their ripple effects are difficult to predict. This macroeconomic environment directly affects various financial asset markets, including stocks and cryptocurrencies.

Indeed, in the cryptocurrency market, an unstable supply and demand structure has been observed where large investors (whales) in XRP (Ripple) are selling off their holdings to realize profits, and individual investors are buying them up. This is interpreted as a typical precursor to a bearish reversal, increasing tension about a sharp price drop. Even the price of gold, considered a safe-haven asset, is observed to fluctuate depending on the earnings announcements of big tech companies. Ultimately, this proves that a cautious approach is needed to protect asset values during unstable times.

• Global Uncertainty: Unpredictable variables like U.S. political events exist.
• Cryptocurrency Market Instability: XRP whale selling and individual buying raise concerns about a downturn.
• Safe-Haven Asset Volatility: Gold prices also sensitive to external factors like big tech earnings.

The value of money is not immutable. From Iran’s hyperinflation crisis to South Korea’s latent instability and the unpredictable trends in global financial markets, the world of money we encounter daily is constantly changing. In such times, wisdom is desperately needed to coolly analyze phenomena and establish one’s own standards rather than blindly following trends. Gaining insight into money is the way to protect our lives.

Frankly, XRP has long been associated with the image of a “remittance coin.” But now, it’s evolving beyond a simple remittance tool into a financial platform where massive capital moves. The recent news of its full integration into the Solana ecosystem and the launch of ‘wXRP’ surprised many. It’s certainly enough to capture significant market attention.

XRP Ledger Opens New Horizons in the Real-World Asset (RWA) Tokenization Market

The XRP Ledger is currently showcasing an unprecedented presence in the RWA market. Over the past month, RWA transfer volume within the network surged by an astonishing 875%, reaching $101.7 million (approximately 140 billion KRW). It’s not just the transfer volume that’s growing. The total RWA value on the XRP network is currently around $2.498 billion (approximately 3.45 trillion KRW), on the verge of breaking $2.5 billion. Isn’t that incredible?

Notably, $1.482 billion in new assets have flowed in this year alone, demonstrating rapid growth. This is a strong signal that users are moving beyond simply holding assets to actively utilizing them within the network. Experts believe this improved liquidity will be a harbinger of major global institutions entering the market.

• RWA Transfer Volume Surge: Increased by 875% in one month, reaching $101.7 million.
• Total RWA Value Advancement: Approximately $2.498 billion, nearing $2.5 billion.
• New Asset Inflow: An additional $1.482 billion flowed in this year alone.

Joining the Solana Ecosystem and Launching ‘wXRP’: The Beginning of Cross-Chain Expansion

Another hot topic for the XRP Ledger is its integration into the Solana ecosystem. With the official launch of ‘wXRP’ on the Solana network, XRP can now be utilized in various Solana-based decentralized applications (dApps). It’s also worth noting that major partners like Ripple, Hex Trust, and LayerZero participated in this collaboration.

Immediately after this news broke, the XRP price surged by 5.15% in a single day, touching the $1.50 mark. Solana (SOL) also rose by over 4%. I believe this signifies more than just asset movement; it represents the combination of the XRP Ledger’s strengths – fast transaction speeds and low costs – with Solana’s robust user base. It feels like the barriers between blockchains are rapidly breaking down through cross-chain technology.

• Official wXRP Launch: XRP can now be used on the Solana network.
• Key Partner Participation: Ripple, Hex Trust, LayerZero, etc.
• Market Reaction: XRP price surged 5.15% immediately after the announcement.

XRP Ledger’s Technical Evolution: XLS-66 Amendment and Market Changes

The XRP Ledger’s technical evolution continues. Validators are currently voting on two amendments, XLS-65 and XLS-66, aimed at enabling lending and improving vault functionalities. However, for these amendments to pass, they require approval from over 80% of all validators, so there’s still a long way to go.

Specifically, an analysis suggests that XLS-66 differs from the ‘easy passive income’ many investors anticipate. Instead of automatically paying interest like a regular deposit, users deposit XRP into a vault and receive ‘Multi-Purpose Tokens (MPTs),’ and the value of the share represented by these MPTs increases. To realize actual profit, one must go through the process of redeeming MPTs back into XRP, so it’s important not to misunderstand it as a ‘money-printing machine.’ Alongside these technical changes, XRP recently surpassed BNB to claim the 4th spot in market capitalization. This can be attributed to a combination of positive factors, such as the launch of the RLUSD stablecoin and increased regulatory clarity.

• XLS-65 and XLS-66 Amendment Voting: Aims to improve lending and vault functionalities.
• XLS-66 Revenue Model: Share value appreciation through Multi-Purpose Tokens (MPTs), not automatic interest payments.
• XRP Market Cap Increase: Surpassed BNB to rank 4th.

The XRP Ledger seems to be going full throttle, emerging as a core player in the RWA market and expanding its cross-chain presence by partnering with the Solana ecosystem. While there are still challenges to address, such as technical amendment voting and complex revenue structures, its future trajectory looks truly promising. It will be crucial to closely monitor these evolving trends.

This situation is quite ironic, actually. The Ethereum ecosystem continues to strengthen fundamentally, from the development of Layer 2 solutions to the increasing demand for stablecoin payments and the growth in staked ETH. Even with the recent approval of spot Ethereum ETFs in the US, institutional investor capital continues to flow in. Today, I want to delve into this ‘unbalanced’ situation of Ethereum.

Ethereum Network: The Real Reason Behind Record-High Activity

The fact that Ethereum recorded 200.4 million mainnet transactions in Q1 2026, reaching an all-time high, is truly remarkable. A 43% increase from the previous quarter is proof of how actively the Ethereum network is operating. But there are a few key reasons behind this increase in activity.

• Activation of Layer 2 Solutions: Ethereum has been actively promoting Layer 2 solutions to address its chronic problems of high gas fees and slow processing speeds. Layer 2 networks like Arbitrum and Optimism significantly reduce transaction costs, leading to more users.
• Increased Demand for Stablecoins: Stablecoins play a crucial role in global on-chain transactions, and over half of stablecoin transactions occur on Ethereum L1 and L2. As demand for digital assets with stable value grows, so does the utilization of the Ethereum network.
• Impact of the Dencun Upgrade: Do you remember the Dencun upgrade that took place last year (2024) in March? With the introduction of EIP-4844, also known as ‘Proto-Danksharding,’ Layer 2 transaction costs were dramatically reduced. This significantly contributed to the increase in network activity.

In fact, Ethereum founder Vitalik Buterin had expected gas fees to decrease by about 60 times or more after the Dencun upgrade, and these effects are indeed being observed. The network is truly growing properly.

Why Has the Price Halved? Conflicting Market Views

It’s honestly hard to understand why Ethereum’s price has fallen by over 50% from its peak, despite record-high network activity. When fundamentals are so strong, but the price is struggling, it suggests the market is looking at other factors. Let’s pinpoint a few:

• Macroeconomic Uncertainty: No matter how well Ethereum performs, if the macroeconomic situation is unfavorable, investor sentiment is bound to shrink. External factors like geopolitical tensions or interest rate hikes are putting pressure on the entire cryptocurrency market.
• Decoupling from Bitcoin: In the past, when Bitcoin rose, Ethereum tended to follow suit, but that’s not always the case anymore. Bitcoin is increasingly seen as ‘digital gold’ by institutional investors, leading to more independent movements. While Ethereum has a strong identity as a ‘productive asset,’ the market still isn’t matching Bitcoin’s rally.
• Profit-Taking Pressure and Tokenomics Concerns: Since many investors bought at the peak, even small rebounds can trigger a flood of profit-taking sales. There are also some concerns about a slowdown in value accumulation after the Dencun upgrade. These factors combined may be limiting price increases.

There was also recent news that Bitmine, an Ethereum treasury management firm, reported a $3.8 billion loss in Q1. Such news can also affect investor sentiment.

Nevertheless, Expectations for Ethereum Remain High?

While Ethereum’s price performance has been somewhat disappointing, I believe there are still many reasons to be optimistic from a long-term perspective. There are even predictions that Ethereum could reach $8,600 by 2026.

• Continued Inflow from Institutional Investors: The fact that the US spot Ethereum ETF recorded net inflows for six consecutive trading days is definitely a positive sign. Large institutions like BlackRock investing in Ethereum means they recognize its value and are looking at it long-term.
• Center of Real-World Asset (RWA) Tokenization: BlackRock CEO Larry Fink also stated that “all funds will exist in tokenized form on the blockchain,” and currently, most global financial institutions are tokenizing real-world assets on Ethereum. This suggests that Ethereum is highly likely to become a core infrastructure of the future financial system.
• Overwhelming Security and Liquidity: Ethereum is supported by over 1 million validators across 84 countries, and the fact that it has never experienced downtime since its launch in 2015 is truly astonishing. This unparalleled security and its dominant role in stablecoin transactions are unique strengths of Ethereum that other blockchains cannot easily replicate.

Honestly, the current Ethereum price is frustrating. The network is growing like crazy, but the price is stagnant. But then again, this situation might actually be an undervalued period. Institutions might be quietly accumulating. Ultimately, time will tell, won’t it?

Frankly, many people get a headache when complex technical discussions come up, right? But the more you learn about Polkadot, the more you’ll realize, ‘this is truly something special.’ I’ll explain why Polkadot is receiving so much attention and what future it envisions, in an easy and fun way, as if I were explaining it to a friend.

The Core of Blockchain Connectivity: Relay Chain and Parachain Structure

Polkadot’s biggest feature lies in its unique network structure. Like a central highway and various local roads, the main chain called the Relay Chain is responsible for the overall network security and consensus, and numerous Parachains are connected to it. These parachains are independent blockchains optimized for their respective roles, and the real charm is that they can be freely designed for specific purposes.

Thanks to this structure, Polkadot excels at solving the interoperability problem where multiple blockchains exchange data and share assets with each other. It overcomes the limitations of existing blockchains that were isolated from each other, allowing them to operate organically within a single ecosystem. This is the fundamental rule, like the ‘internet of blockchains’ that Polkadot dreams of.

• Relay Chain: The heart of the Polkadot network, responsible for overall consensus and security.
• Parachain: An individual blockchain developed for a specific purpose, connected to the Relay Chain to share security while operating independently.
• Bridge: Acts as a bridge connecting external blockchains like Bitcoin or Ethereum to the Polkadot network.

Polkadot 2.0 Innovations: Coretime and Async Backing

The Polkadot 2.0 upgrade, introduced in 2025, brought enormous changes to the network’s operating model. In particular, the concept of Coretime allowed for flexible leasing of computing resources as needed, replacing the previous fixed parachain slot auction method. From a developer’s perspective, the barrier to entry has been significantly lowered, and network resource utilization has been maximized, which I consider a truly achievable innovation.

With the addition of Async Backing technology, block generation speed has become much faster. As a result, transaction processing speed has dramatically improved, and scalability issues have been effectively resolved. These technological advancements are promoting the development of various decentralized applications (dApps) such as DeFi, blockchain games, and asset tokenization.

• Coretime: Allows for flexible purchase of blockchain computing resources in the market, reducing development cost burdens.
• Async Backing: Shortens the block generation interval of parachains, significantly improving network throughput and scalability.
• Improved Cross-Chain Messaging: Makes data exchange between different chains faster and more secure, enhancing interoperability.

The Completion of Decentralization: Strong Governance and Web3 Vision

Polkadot goes beyond being a mere technical platform; it has a clear vision to create a truly decentralized world. At its core is a powerful On-chain Governance (OpenGov) system. Any DOT token holder can propose and vote on network upgrades or policy changes. What’s truly important about this is that the network can be continuously developed without hard forks.

In March 2026, there was also a significant change where the annual issuance of DOT tokens was substantially reduced. With the total supply limited to 2.1 billion, many analysts believe it will have a positive impact on long-term value appreciation. I believe this governance system and token economy are essential elements in making Polkadot’s Web3 era, a ‘fair internet’ where users are the owners, a reality.

• OpenGov: A transparent and efficient governance system where DOT token holders directly participate in key network decisions.
• DOT Token Role: Used for governance participation, staking for network security, and securing parachains (or Coretime).
• Web3 Vision: Aims to build a decentralized internet environment where users control their data and assets, free from censorship.

How was our discussion about Polkadot today? While there are many technical aspects, the fact that all of this is an effort to create a better internet world is truly impressive. I’m excited to see how Polkadot will lead the Web3 era in the future.

U.S. Securities and Exchange Commission, Why Was It Created?

In fact, once you understand the background of the U.S. Securities and Exchange Commission (SEC)’s birth, you’ll naturally realize its importance. Back in 1929, the U.S. stock market crashed, the Great Depression hit, and investor confidence plummeted, right? It was then that President Roosevelt, determined to prevent such an event from happening again, established the SEC in 1934 as an independent federal regulatory agency.
Their core mission is threefold: First, to protect investors. Second, to ensure that the securities market operates fairly and orderly. Third, to facilitate capital formation. Joseph P. Kennedy, the first chairman, reportedly laid the groundwork for the SEC by relentlessly cracking down on unfair trading and insider trading, drawing from his own experience(?) of committing all sorts of illegal acts in the securities industry. Ironic, isn’t it? Perhaps that’s why the agency’s strictness and fairness continue to this day.

Virtual Asset Regulation: No Longer a Security?

One of the hottest topics in today’s investment market is virtual assets, or the crypto market, right? For the past 10 years, there has been an ongoing debate between the U.S. Securities and Exchange Commission and the industry over whether crypto is a ‘security’ or not. But in March 2026, the SEC finally issued an official statement: major virtual assets like Bitcoin and Ethereum are ‘digital commodities,’ not ‘securities.’
Frankly, I believe this announcement significantly reduced market uncertainty. Furthermore, the SEC even signed a Memorandum of Understanding (MOU) with the Commodity Futures Trading Commission (CFTC) to coordinate regulatory roles. Now, the big picture of the U.S. virtual asset oversight system is beginning to take shape. This means that those who have been troubled by regulations while investing in crypto can breathe a sigh of relief. Of course, it’s still too early to be entirely optimistic as congressional legislative processes remain, but it’s clearly an important first step.

Tokenized Assets and the Ambition of ‘Project Crypto’

Just as noteworthy as virtual asset regulation is the SEC’s movement regarding tokenized assets. Recently, the U.S. Congress and regulatory authorities have been accelerating discussions on the introduction of tokenized assets. The SEC is preparing to introduce an ‘investment innovation exemption’ for tokenized assets, which is highly likely to function as a type of regulatory sandbox. Simply put, it’s a temporary suspension of regulations to help new technologies establish themselves in the market.
In particular, the SEC, led by Chairman Paul Atkins, is pursuing an ambitious plan called ‘Project Crypto.’ This is a vision to move the traditional securities market onto the blockchain to create a market with instant settlements, which could completely overturn the financial market landscape if realized. However, there are also voices from Wall Street urging caution, arguing that such broad regulatory exemptions could weaken investor protection and cause market confusion. It seems the tug-of-war between innovation and stability will continue.

SpaceX IPO: The Largest in History is Coming?

The SEC’s role is not limited to the crypto market. Their presence in the traditional securities market remains strong. Just in April 2026, news broke that Elon Musk’s SpaceX confidentially submitted a draft registration for an Initial Public Offering (IPO) to the SEC. They are aiming for a June listing, and if successful, it would be the largest IPO in history – absolutely wild, right?
Such a massive IPO is only possible after thorough review by the SEC. Their crucial role is to meticulously examine the extensive documents submitted by companies and ensure that sufficient information is provided to investors. While this process is complex and time-consuming, I believe it is an essential procedure for protecting investors and maintaining market transparency. If such a process didn’t exist, the stock market would probably be a much more chaotic place.
It truly seems like the U.S. Securities and Exchange Commission is working non-stop. From virtual asset regulation to tokenization and mega-IPOs, every decision they make has an enormous ripple effect on the global financial market. I think it’s the attitude of a wise investor to continue paying attention to the SEC’s actions in the future. Well then, I’ll be back with another interesting story next time!
