🔐 What Is Crypto Staking? A Beginner’s Guide

Yogi Nelson

Welcome to the BlockchainAIForum

As the crypto ecosystem continues to evolve, one term that frequently comes up is “staking.” But what exactly does staking mean, and why is it important in the blockchain world? This guide will break down staking in a clear, concise way—covering how it works, who participates, what the benefits and risks are, and what regulators are saying.

🌱 What Is Staking?

Staking is the process of locking up your cryptocurrency to support the operations of a blockchain network. In return, you earn rewards—usually more of that same cryptocurrency. It’s a bit like earning interest in a traditional savings account, except instead of a bank, you’re helping a decentralized blockchain stay secure and functional.

🧠 How Does Staking Work?

Staking is central to a type of blockchain consensus mechanism known as Proof of Stake (PoS). Unlike Proof of Work (PoW)—which relies on energy-intensive mining—PoS requires users to stake (i.e., lock up) tokens to help validate transactions and secure the network. The more you stake, the higher your chances of being selected to validate blocks and earn rewards. Here’s how it works:

  1. You hold a PoS-supported cryptocurrency (e.g., Ethereum, Cardano, Solana).
  2. You lock up your tokens in a wallet or with a staking provider.
  3. The network selects stakers (or validators) to confirm transactions.
  4. You earn staking rewards, typically paid out regularly.

Who Can Stake:

Anyone with supported tokens can stake. There are three main ways to participate:

  • Solo staking: You run your own validator node. This requires technical expertise and minimum token requirements (e.g., 32 ETH for Ethereum).
  • Pooled staking: You join a group of stakers to combine assets and share rewards. Good for beginners.
  • Exchange staking: Centralized platforms (like Coinbase or Binance) offer staking-as-a-service.

💰 What Are the Benefits? There are several advantages to staking your crypto.

✅ Earn Passive Income: Stakers receive regular rewards—similar to earning interest. This can be a valuable source of income for long-term holders.

✅ Support the Network: By staking, you’re helping secure the blockchain and process transactions, contributing to its decentralization.

✅ Lower Energy Use: Unlike mining, staking doesn’t require heavy computing power or electricity, making it more environmentally friendly.

⚠️ What Are the Risks? Staking isn’t risk-free. Consider the following before jumping in:

❌ Lock-Up Periods: Some networks require you to lock your tokens for a set period. During that time, you can’t sell or trade them.

❌ Slashing: If a validator behaves maliciously or makes errors, a portion of staked funds may be “slashed” (penalized).

❌ Platform Risk. If you stake through a third party (like an exchange), your funds depend on their security and practices.

❌ Market Volatility. If you stake through a third party (like an exchange), your funds depend on their security and practices.

🏛️ What Are Regulators Saying?

🇺🇸 United States. The U.S. Securities and Exchange Commission (SEC) has raised concerns that staking services offered by exchanges may qualify as unregistered securities offerings. In 2023, Kraken paid a $30 million fine and shut down its staking service for U.S. users. The main issue lies in custodial staking—when a third-party holds users’ assets and manages staking on their behalf. However, with a crypto friendly administration in place the coast is clear!

🇪🇺 Europe. In the EU, regulators are taking a more measured approach, aiming to provide clarity through the Markets in Crypto-Assets (MiCA) regulation. MiCA may allow staking under clear consumer protection guidelines. Regulatory frameworks are still evolving. Crypto users should stay informed and compliant in their respective jurisdictions.

🔍 Tips for Beginner Stakers. If you’re new to staking, follow these best practices:

  • ✅ Research the blockchain you want to stake on (e.g., its inflation rate, validator performance, and reward schedule).
  • ✅ Use a reputable wallet or exchange with transparent fees and security.
  • ✅ Start small to learn how the process works before committing large amounts.
  • ✅ Stay updated with network upgrades and policy changes.

🧭 Popular Staking Coins. Here are a few major cryptocurrencies that support staking:

CoinNetworkEst. Annual Reward
EthereumEthereum 2.0~3–5%
CardanoADA~3–6%
SolanaSOL~5–8%

To stake, or not to stake, that’s the question. By now you should know the answer.

📈 The Rise of Tokenized Stocks: A Beginners Guide

Yogi Nelson

Welcome to the BlockchainAIForum

Investing is changing at lightning speed thanks to blockchain technology. One of the most exciting innovations is tokenized stocks. But what exactly are they? How do they work? Why do some investors love them while others worry? Let’s break it down step by step!

🪙 What Are Tokenized Stocks?

Tokenized stocks are digital representations of real-world stocks on a blockchain. Imagine buying shares of Apple or Tesla—but instead of going through a traditional brokerage, you receive tokens on a blockchain that mirror the value of those stocks. Each token typically represents one share (or even a fraction of one share) of a company. These tokens can be traded on blockchain-based platforms just like cryptocurrencies.

🛠️ How Do Tokenized Stocks Work? (Step by Step)

Let’s go through it from start to finish:

1️⃣ Underlying Asset

A real-world stock (for example, Tesla stock) exists and is held in custody by a licensed broker or institution. This entity ensures that the tokens are backed 1:1 by real shares.

2️⃣ Token Creation

A blockchain platform issues tokens representing these shares. Smart contracts automate issuing, transferring, and recording ownership.

3️⃣ Buying and Selling

Investors buy these tokens on crypto exchanges that support them, trading them much like Bitcoin or Ethereum.

4️⃣ Fractional Ownership

Unlike traditional stocks that might require buying whole shares, tokenized stocks allow fractional ownership. You can buy 0.1 of an Apple share, making investing more accessible.

5️⃣ Settlement on the Blockchain

Transactions settle on-chain, recording ownership changes immediately or within minutes instead of days.

💡 Advantages of Tokenized Stocks

  • ✅ 24/7 Trading
    Unlike traditional stock markets that close overnight and on weekends, tokenized stocks can trade at any time.
  • ✅ Global Access
    Anyone with an internet connection and a crypto wallet can invest, opening markets to investors in regions without traditional brokerages.
  • ✅ Fractional Shares
    Tokenization lowers the barrier to entry. Instead of buying a whole $1000 share, you can invest $10.
  • ✅ Faster Settlement
    Blockchain-based settlement can be near-instant, reducing counterparty risk and eliminating some middlemen.
  • ✅ Improved Transparency
    All transactions are recorded on-chain, enhancing traceability and auditability.

⚠️ Disadvantages of Tokenized Stocks

  • ❌ Regulatory Uncertainty
    Regulators are still figuring out how to treat these assets. This uncertainty can lead to sudden changes in availability.
  • ❌ Counterparty Risk
    Tokens are only as good as the custodian holding the real shares. If that custodian is dishonest or goes bankrupt, the backing can vanish.
  • ❌ Limited Platforms
    Not all exchanges support tokenized stocks. Liquidity can be limited compared to traditional markets.
  • ❌ Jurisdictional Restrictions
    Many tokenized stocks cannot legally be sold in certain countries (for example, the U.S.) due to securities laws.

⚖️ The State of Regulations

Regulation is the biggest wild card in the future of tokenized stocks.

  • In the United States, the SEC generally considers these tokens securities. Selling them without proper licenses can be illegal.
  • Some platforms have previously offered tokenized stocks without full regulatory approval, drawing heightened scrutiny.
  • The European Union is taking a more controlled approach. The EU’s MiCA (Markets in Crypto-Assets) framework sets rules for digital assets, but tokenized stocks may fall under existing securities laws.
  • Countries like Switzerland and Singapore have clearer guidelines encouraging innovation while protecting investors.

In short, the landscape is fragmented. Companies issuing tokenized stocks must navigate a patchwork of local laws and face the risk of regulatory crackdowns.

🌍 Real‑World Example: Robinhood’s Tokenized Stocks in Europe

In June 2025, Robinhood made headlines by launching tokenized U.S. stocks and ETFs for users in the European Union and European Economic Area. Through a partnership with the Arbitrum blockchain, Robinhood offers over 200 stock and ETF tokens, including major companies like Apple, Nvidia, and Microsoft, as well as private firms such as OpenAI and SpaceX.

🎁 Launch Incentive & Scope

Robinhood incentivized early adoption by giving European users who onboarded before July 7, 2025, €5 worth of OpenAI and SpaceX tokenized shares. However, these tokens are backed by a special purpose vehicle (SPV) and do not confer actual ownership, voting rights, or dividends.

🚀 Market Impact & Strategy

Robinhood’s stock price surged as much as 12–13%, hitting record highs after the announcement. Analysts see this move as a major revenue expansion opportunity, with the potential to scale globally as regulation evolves. Robinhood is also developing its own Layer 2 blockchain optimized for tokenized real-world assets.

🧾 Key Considerations

  • Synthetic Exposure: These tokens offer price exposure but do not represent real equity. OpenAI, for example, publicly distanced itself from the offering, clarifying it was launched without its authorization.
  • Regulatory Scrutiny: Authorities such as Lithuania’s central bank and the European Securities and Markets Authority (ESMA) are reviewing the offering to ensure compliance with securities laws.

Robinhood’s European launch shows both the promise of tokenized stocks—greater accessibility, 24/7 trading—and the complexities of regulation and legal frameworks.

🔮 The Future of Tokenized Stocks

Tokenized stocks aim to democratize investing, making it cheaper, faster, and more global. If regulators can agree on consistent, investor-friendly rules, tokenized stocks could become as mainstream as ETFs.

But challenges remain. The sector will need:

  • Stronger custodial frameworks
  • Clearer, harmonized regulations
  • Greater public awareness and education

📌 Conclusion

Tokenized stocks are a compelling example of blockchain reshaping traditional finance. By enabling fractional, 24/7, globally accessible trading, they break down old barriers. But they also introduce new risks—especially around regulation and custodial integrity.

As the technology matures, we may see the best of both worlds: the reliability of traditional markets combined with the innovation of blockchain. For now, investors should stay informed, understand the risks, and watch the evolving regulatory landscape carefully.

Tornado Cash Legal Update: OFAC Sanctions Lifted

Yogi Nelson

Welcome to the Blockchain & AI Forum, where your questions are answered!  Today I answer Malik’s question: “what’s the latest news in the Tornado Cash legal case”?

What is Tornado Cash. Before jumping to the answer, first a moment to understand what is Tornado Cash.  Tornado Cash is a non-custodialprivacy protocol allowing permissionless shielded transactions on Ethereum and derivative networks. In plain English, Tornado Cash is an application that does not hold your crypto currency–you own it, you store it.  Tornado Cash facilitates transactions on the Ethereum blockchain without requiring permission while maintaining your privacy.  How does Tornado Cash maintains privacy?

Tornado Cash = Privacy.  Tornado Cash achieves anonymity by breaking the on-chain link between source and destination addresses through “anonymity pools”.  However, Tornado Cash does not preserve privacy by comingling assets; it uses zero knowledge cryptography.  What’s more, Tornado Cash relies on Ethereum—a decentralized protocol where transactions neither can be changed or altered.  Hence, nobody – including the original developers – can modify or inhibit the protocol or the transactions. What more information about how Tornado Cash works?  Click   How does Tornado Cash work? and Tips to remain anonymous.

What is the Office of Foreign Assets Control—OFAC.  OFAC is an office within the U.S. Treasury Department.  It claims to enforce economic and trade sanctions against specific countries, regimes, individuals, and entitles that pose threats to U.S. national security, foreign policy, or economy.  In other words, the enemy de jour of the U.S. government.  By the way, although OFAC was formally created in 1950, the use of sanctions by the U.S. government goes back to 1812! 

Tornado Cash Placed on OFAC Sanction List. August 8, 2022, OFAC placed Tornado Cash on the sanctions list.  According to the OFAC press release https://home.treasury.gov/news/press-releases/jy0916, “Tornado Cash, is a crypto currency mixer which has been used to launder more than $7 billion worth of virtual currency since its creation in 2019.”  However, OFAC’s statement is partially incorrect on the facts.  Tornado Cash is not a currency mixer nor is it property.  This error, deliberate or not, is materially important as we will see in a moment.  Let’s move on to what happened last week.

OFAC Removes Tornado Cash from the Sanction List.  Last week, the U.S. Treasury removed Tornado Cash from its sanctions list.  That’s a big deal. To understand what happened let’s take a moment to examine a recent court ruling that led to OFAC removing Tornado Cash from the sanctions list.

Last November, the 5th District Court of Appeals ruled that OFAC exceeded its authority when it put Tornado Cash on the sanctions list.  Essentially, the Court of Appeals reversed an earlier decision by a lower federal court.  The Court of Appeals stated the executive branch’s authority to “block ‘property’ in which a foreign ‘national’ or ‘person’ has an ‘interest’” did not apply in the case of Tornado Cash.  In other words, OFAC has no jurisdiction.  Why?  Because the use of immutable smart contracts — lines of autonomous code on the blockchain intended to preserve anonymity in transactions — do not qualify as property and OFAC can only sanction property.  And, smart contracts, despite their names, are not actually contracts. By the way, Tornado Cash’s legal fees were paid by Coinbase.  Wonderful to have friends with cash! 

No surprise—Tornado Cash value catapulted by 73% after the OFAC full scale retreat.  The story ends with OFAC deciding to “exercise its discretion” by dropping legal actions against Tornado Cash.  Lol!

Challenges and Opportunities in DeFi: University of Zurich’s Taxonomy Report

Yogi Nelson

Namaste Yogis. Welcome to the Blockchain & AI Forum, where your technology questions are answered! Here no question is too mundane. As a bonus, a proverb is also included. Today’s question was submitted by Liz from Paraguay, and she wants to know the latest university research findings on decentralized finance (DeFi).

Liz, you came to the right place. After receiving your question, it piqued my curiosity. Guess what? I found a treasure source of information! Before jumping into the findings, I’ll start by defining DeFi for new members to my blog.

Investopedia says, DeFi is an emerging financial technology, consisting of blockchains, software, and secure distributed ledgers, analogous to those used by crypto currencies. DeFI technology removes third parties and centralized institutions from financial transactions. DeFi challenges traditional finance by empowering individuals with the power to conduct peer-to-peer transactions. Now let’s discuss a research report produced by the University of Zurich, called “A Taxonomy for Decentralized Finance.”
https://www.zora.uzh.ch/id/eprint/254150/1/1_s2.0_S1057521924000152_main.pdf

Finding 1: Ethereum Reigns Supreme
Ethereum founders loved Bitcoin but noticed its limited utility. Their solution was to create Ethereum in 2014 as a second generation blockchain project that could be programmed to run on “smart contracts.” Smart contracts are code written into a blockchain that executes the actions two parties agree to outside the chain. By automating these actions, the need for an intermediary or trust between the parties is removed, and BOOM, you get the foundation upon which DeFi is constructed.

DeFi start-ups love Ethereum. In fact, 36% of all DeFi start-ups use Ethereum as their base layer technology. There are alternatives to Ethereum, including Solana, Cardano, etc. but no other layer one blockchain comes close to Ethereum for DeFi start-ups.

Finding 2: DeFi is Moving Towards Decentralized Governance
DeFi start-ups are built with the goal of eventually becoming decentralized in their governance. This is not surprising. After all, DeFi is constructed on the premise, perils, and promise of decentralization. Earlier this year, the Securities and Exchange Commission (SEC) approved Bitcoin and Ethereum ETFs. The SEC relented and finally recognized the decentralized nature of their governance. Other decentralized layer one blockchain projects may also receive SEC future approval relatively soon.

Finding 3: DeFi Systems Need Interoperability
Blockchain projects are monolingual. Essentially, blockchains don’t “communicate” well with each other. DeFi will not surpass traditional finance until interoperability becomes a DeFI reality.

Today, DeFi projects are essentially incapable of interacting with one another. Yes, there are “bridges” that connect blockchains. However, existing bridges are slow, weak, and incapable of sustaining a large-scale financial system. As Cardano founder Charles Hoskinson has said dozens of times, “… blockchains need to become as interoperable as Wi-Fi for mass adoption to take root.”

Finding 4: Regulatory Risk
DeFi pioneers are sailing unchartered regulatory waters. I’m not referring to fraud. Fraud is illegal regardless of technology and there are plenty of existing laws against fraud. I’m referring to the failure of Congress to pass DeFi legislation. The result? The SEC has stepped into this power vacuum and has deployed its enforcement authority to decide DeFi policy! Unelected bureaucrats are the bosses. What’s worse, SEC is a captured regulator. Captured by who? Captured by the industry it regulates and the incumbents are not too keen on opening the door to competition.

Let’s end with a proverb from Paraguay, where they are fond of saying: “… a lamb with a little mark will eventually leave the flock”.

Until next time,

WHAT DID VITALIK BUTERIN RECENTLY SAY ABOUT ARTIFICIAL INTELLIGENCE

Yogi Nelson

Namaste Yogis. Welcome to the Blockchain & AI Forum, where questions are answered, mostly correct! Here no question is too mundane. As a bonus, a proverb is also included. Today’s question comes from Art in San Francisco, CA. Art asks what does Vitalik Buterin think of artificial intelligence?

Art, you came to the right place. Before I explain Vitalik’s thoughts, let’s know Buterin first. Vitalik is a 29-year-old Russian Canadian computer programmer and a co-founder of Ethereum. Ethereum is a decentralized blockchain network, known for pioneering smart contracts, among other advancements in computation. From an early age Vitalik demonstrated an amazing ability to grasp mathematics and computer science. That’s not a surprise given his father was a computer scientist. Holy, like father, like son, Batman! Given his genius with computers, it makes sense you would ask what Vitalik makes of AI.

On November 23, Vitalik published his “My Techno Optimism” paper.
https://vitalik.eth.limo/general/2023/11/27/techno_optimism.html?ref=bankless.ghost.io Vitalik’s summary perspective is below followed by highlights from across the major points of his paper.

“I believe in a future that is vastly brighter than the present thanks to radically transformative technology, and I believe in humans and humanity. I reject the mentality that the best we should try to do is to keep the world roughly the same as today but with less greed and more public healthcare. However, I think that not just magnitude but also direction matters. There are certain types of technology that much more reliably make the world better than other types of technology. There are certain types of technology that could, if developed, mitigate the negative impacts of other types of technology. The world over-indexes on some directions of tech development, and under-indexes on others. We need active human intention to choose the directions that we want, as the formula of “maximize profit” will not arrive at them automatically.”

Vitalik Buterin, My Techno-Optisium

Buterin argues there are very high costs to delaying technological progress. He cites life expectancy improvements and the internet, as evidence for not holding back technological advancements. Vitalik makes the case for using advancements in AI to solve environmental challenges, including climate change.

Vitalik believes AI is fundamentally different from previous advancements in technology and therefore requires significantly more consideration. Vitalik says AI is the creation of a new and powerful brain whereas previous inventions were contraptions. “AI is a new type of mind that is rapidly gaining in intelligence, and it stands a serious chance of overtaking humans’ mental faculties and becoming the new apex species on the planet”, says Buterin. Vitalik cites scientists that are worried AI could wipe out humanity! Holy doomsday, Batman!

Buterin, is equally concerned with “digital authoritarianism”. Vitalik points out Open AI, with a mere 500 employees, services 100,000,000 customers with immensely powerful machines! Power could be centralized by just a handful of people one day, is Vitalik’s worry.

Vitalik pens a lengthy narrative regarding the e/acc movement. According to Vitalik, e/acc is “… fundamentally about an appreciation of the truly massive benefits of technological progress, and a desire to accelerate this trend to bring those benefits sooner.” Jeff Bezos is the most prominent advocate. In a point-by-point fashion, Buterin shares what he believes are the implications of e/acc across a range of topics, including: military technology, decentralized governance, cyber security, multi-planetary living, world government, to name a few topics.

We conclude today with this proverb from the Dominican Republic: With patience and calm, a donkey can climb a palm tree. Well said my Caribbean brethren!

Until next time,
