🔮 How Oracles Work in the Blockchain World — Featuring Chainlink

Yogi Nelson

by Yogi Nelson

Welcome to the BlockchainAIForum

🧱 What Is an Oracle?

An oracle is a service that provides external data to a blockchain. It tells the blockchain what’s going on in the real world so that smart contracts can act on that data. But of course there is more to the story and if you stay with me for three minutes, you will gain a deeper understanding. Let’s dive in.

Why Do Blockchains Need Oracles?

Blockchains are closed systems. They are deliberately isolated from the outside world to remain secure and tamper-proof. However, many blockchain applications—especially smart contracts—need real-world data to function. Examples include:

– Sports scores for betting apps
– Weather conditions for crop insurance
– Stock prices for decentralized finance (DeFi)
– Currency exchange rates for cross-border payments

⚙️ How Do Oracles Work?

Oracles act like data messengers, feeding smart contracts the trusted information they need. Perhaps think of an oracle as a messenger. Let’s walk through a simple example: A decentralized insurance contract pays out to farmers if rainfall in a certain area is below a specified threshold. Here’s how oracles help:

1. Smart Contract Request: The insurance contract sends a request for weather data.
2. Oracle Receives Request: The oracle picks up the request and fetches the required data (e.g., from a weather API).
3. Data Is Verified: The data is often verified or corroborated across multiple sources to ensure it is accurate.
4. Data Is Delivered: The oracle sends the verified data back to the smart contract.
5. Action Is Taken: Based on the data, the smart contract executes its logic—e.g., issuing a payout.

🔐 The Problem with Centralized Oracles

If you use just one oracle to provide this data, you create a central point of failure. What if that oracle lies, is hacked, or goes offline? Suddenly, the whole smart contract system becomes compromised. This defeats the purpose of using decentralized technology in the first place. Hence, decentralized oracles are the solution—bringing multiple data sources and multiple oracles together to reach consensus and maintain integrity.

🌐 Enter Chainlink: The Leading Oracle Network

Chainlink is the most widely adopted decentralized oracle network in the blockchain space. Launched in 2017 by Sergey Nazarov and Steve Ellis, Chainlink was designed to solve the “oracle problem”—how to bring secure and reliable off-chain data onto the blockchain without introducing a point of failure.

🧩 How Chainlink Works

Chainlink operates through a decentralized network of nodes that provide external data to smart contracts. Here’s a high-level overview:

📝 1. Request Initiation. A smart contract emits a request for data. Chainlink picks it up.

👥 2. Oracle Selection. Chainlink matches the request to a set of independent oracles. These nodes are chosen based on reputation and performance metrics.

📡 3. Data Aggregation. Each oracle retrieves data from external sources (APIs, IoT devices, market data feeds, etc.). Then, Chainlink aggregates all the responses to eliminate outliers and produce a trustworthy data point.

💎 4. Result Delivery. The final data is delivered back to the smart contract, triggering its execution.

🪙 5. Incentives and Penalties. Oracles earn LINK tokens as payment for honest work. Malicious or inaccurate nodes are penalized by losing stake or reputation.

🛡️ Why Chainlink Stands Out


– Decentralization: No single point of failure; multiple nodes verify the data.
– Data Quality: Chainlink uses multiple premium data providers and APIs.
– Security: Nodes stake LINK tokens, aligning their incentives with accuracy.
– Wide Adoption: Used by projects like Aave, Synthetix, Compound, and even Google Cloud for blockchain integrations.
– Cross-Chain Compatibility: With its Cross-Chain Interoperability Protocol (CCIP), Chainlink can facilitate oracle services across multiple blockchains.

🧠 Chainlink Use Cases

– DeFi: Real-time price feeds for assets (e.g., ETH/USD), interest rates, and lending protocols.
– Insurance: Weather data or flight status for automated claims processing.
– Gaming: Random number generation (RNG) for fairness in blockchain-based games.
– Enterprise: Secure off-chain data feeds from traditional institutions like banks and cloud services.

🔮 The Future of Oracles and Chainlink

Oracles will be crucial to the next phase of blockchain innovation. As smart contracts evolve beyond simple logic to govern real-world activities, oracles will need to deliver ever-more reliable, real-time data. Chainlink’s future lies not just in being an oracle, but in becoming a full-fledged interoperability layer between blockchains and the world. Chainlink is leading the charge in:

– Verifiable randomness
– Proof of reserves
– Secure cross-chain communication
– Zero-knowledge data oracles

🧭 Final Thoughts

Oracles are the unsung heroes of the blockchain world—essential yet often misunderstood. Without them, smart contracts would be powerful but blind. Chainlink provides the vision, security, and scalability that modern decentralized applications (dApps) demand. As Web3 grows, Chainlink’s decentralized oracle network is poised to become a foundational infrastructure—powering everything from finance to insurance to gaming. If you’re building or investing in blockchain projects, understanding oracles—and Chainlink—is no longer optional. It’s essential.

My oracle message is stay informed and until next time,

How the Government of Italy Is Using Blockchain

Yogi Nelson

Exploring the Past, Present, and Future of Public Sector Innovation

by Yogi Nelson

Welcome to the BlockchainAIForum

A Digital Renaissance in the Italian Government

I post this article in honor of Italy from the great city of Milan, Italy! Unbelievable! Italy, a country known for its ancient traditions and rich cultural legacy, is undergoing a quiet digital revolution. I’m hoping to see it and much more. In recent years, the Italian government has embraced blockchain technology not just as a buzzword, but as a functional tool to modernize its public sector. From notarization services to education credentials, Italy is leveraging blockchain for transparency, efficiency, and trust.

📜 A Timeline of Blockchain Adoption in Italy

2018: First Steps
Italy became one of the first European Union countries to formally define blockchain in law. In 2019, the government issued a decree recognizing the legal validity of digital records stored on blockchain—a foundational move that paved the way for official use.

2020–2022: Strategic Framework
The Italian Ministry for Economic Development (MiSE) launched a Task Force on Distributed Ledger Technologies, laying out strategies to promote public-private blockchain initiatives. It also joined the European Blockchain Partnership (EBP), a consortium working toward a cross-border blockchain infrastructure.

🧾 Use Case: Blockchain for Notarization

One of the earliest blockchain applications adopted by the Italian government is document time stamping and notarization. Using blockchain, Italians can certify ownership, creation dates, and authenticity of documents without going through traditional notary services. This includes contracts, intellectual property, and even digital art. In Puerto Rico, where I live, our legal system, shares, and suffers from, many of the same antiquated notarization system. Its awful.

Key Player: Blockchain Italia.io
In collaboration with municipal governments, Blockchain Italia developed Dedit.io, a blockchain-based notarization platform now used by various public entities for legal proof and traceability.

🎓 Use Case: Education Credentials

The University of Cagliari partnered with the Italian Ministry of Education to launch a pilot program that issues blockchain-verified diplomas and academic records. This model is now being reviewed for nationwide rollout, potentially replacing traditional paper certificates.

Benefits include:
– Instant verification of credentials for employers and foreign institutions
– Tamper-proof and accessible from anywhere
– Reduces fraud and administrative overhead

🏛️ Use Case: Public Procurement Transparency

Italy has a long-standing battle against corruption and opaque procurement practices. Blockchain is offering new tools to digitize and audit public contracts.

Pilot Projects:
– Veneto Region initiated a blockchain-based procurement pilot to digitally track bidding processes and vendor compliance.
– Blockchain systems help ensure that once a public tender is published, terms cannot be altered, increasing trust among vendors.

🖼️ Use Case: Cultural Heritage and NFTs

Italy’s Ministry of Culture has partnered with private companies to use blockchain for art and cultural preservation.

Example: Uffizi Gallery in Florence
The museum launched NFT versions of classical artworks like Botticelli’s The Birth of Venus, recorded on blockchain and sold globally. Proceeds help fund restoration and conservation.

Blockchain Utility:
– Ensures provenance of digital replicas
– Protects copyright and licensing for state-owned works

🚦 Regulation and Compliance

The Italian government, while encouraging innovation, maintains a strong focus on regulatory compliance:

– The 2023 Financial Law includes guidance on crypto asset reporting
– CONSOB and Banca d’Italia oversee blockchain finance to prevent misuse

🔮 Looking Ahead: Future Blockchain Use Cases in Italy

National Digital Identity. Plans are underway to integrate blockchain into Italy’s digital ID system (SPID). This would enable decentralized and self-sovereign identity, putting users in control of their own personal data. Be aware my Italian friends–this could lead to more government control.

Voting and Citizen Engagement. Local governments are exploring blockchain-based voting pilots, especially for expatriate Italians who face challenges in secure remote voting.

Health Records. Better sharing of health data, including vaccination certificates and medical histories.

🌍 Italy’s Role in the EU Blockchain Landscape

As part of the European Blockchain Services Infrastructure (EBSI), Italy contributes to cross-border projects involving:
– Customs and tax compliance
– Academic credential recognition
– Digital business registries

This aligns Italy with the EU’s broader digital transformation goals and strengthens its leadership in public sector blockchain adoption.

🧩 Final Thoughts: Tradition Meets Technology

Italy is proving that blockchain isn’t just for tech startups or financial firms—it’s a foundational technology for transparent, secure, and efficient governance. With well-defined laws, pilot programs, and a collaborative approach, the Italian government is helping set the standard for how blockchain can transform the public sector across Europe.

Time to get back to sight seeing in Milan!

The SEC and CFTC Joint Statement: Impact on Crypto Trading

Yogi Nelson

by Yogi Nelson

Welcome to the BlockchainAIForum

The trend is clear–the crypto market exchanges and traditional market exchanges are engaged and eventually heading towards marriage! Why this bold declaration–the news coming from Washington.

In a landmark move on September 2, 2025, staff from the U.S. Securities and Exchange Commission (SEC) and the Commodity Futures Trading Commission (CFTC) issued a joint statement declaring that exchanges registered with either agency are not prohibited from facilitating trading in certain spot crypto asset products. This declaration, emerging from the coordination between the SEC’s Division of Trading and Markets and the CFTC’s Divisions of Market Oversight and Clearing & Risk, marks a clear regulatory pivot in the landscape of U.S. digital asset markets.

Riding the Wave of “Project Crypto” and “Crypto Sprint”

This initiative forms part of broader frameworks known as Project Crypto (by the SEC) and Crypto Sprint (by the CFTC), both born from recommendations of the President’s Working Group on Digital Asset Markets aimed at fostering U.S. leadership in digital finance innovation. The working group’s report consistently called for regulatory clarity to ensure blockchain experimentation thrives on American soil.

Under these programs, the agencies are collaborating to provide a coordinated path forward: emboldening registered venues to offer leveraged, margined, or financed spot retail commodity transactions — including crypto assets — under existing legal authorities.

What’s Allowed, and How It’s Framed

Importantly, the agencies stress that current law already allows certain registered exchanges—namely SEC-registered national securities exchanges (NSEs) and CFTC-registered designated contract markets (DCMs) or foreign boards of trade (FBOTs)—to facilitate trading in select spot crypto commodity products, even with leverage and margin, without needing new legislation.

This is not, however, a new rule or legal exemption. The statement represents staff views only—it carries no binding force and does not change existing statutes. Exchanges must still proceed through the usual regulatory processes, such as filing rule amendments or requesting relief. Nevertheless, its unlikely “staff” would be permitted to take this action without “approval” from the agencies directors. I make this claim as someone who held senior staff positions in the federal government.

What’s Next, and What Market Participants Should Consider

The joint staff statement serves not just as a signal, but as an invitation to market participants. Agencies have pledged to:

  • Promptly review filings and proposals, encouraging engagement from exchanges seeking to list spot crypto products.
  • Address operational and structural questions, including around custody, clearing, margin, and settlement.
  • Support market surveillance and data transparency, encouraging shared price feeds and real-time dissemination of trade data.
  • Balance innovation with investor protection, remaining open to technological advances while ensuring rigorous oversight.

Legal and compliance professionals advise that any firm planning to launch such offerings should prepare thoroughly by addressing these operational points—effectively a checklist for submission—and engage early with regulators.

Views from the Trenches: Optimism vs. Skepticism

The regulatory move has been widely hailed in the industry as a game-changer—a regulatory green light for mainstream U.S. exchanges to consider crypto listings, potentially including Bitcoin and Ether.

But not everyone sees it that way. Some legal analysts have labeled the statement a “nothingburger”, criticizing its non-binding nature and lack of clarity around how “commodity” versus “security” status will be adjudicated—an unresolved core issue in crypto regulation. I do not agree with those legal analysts–but I’m not an attorney nor is this article legal or financial advice.

Harmonizing Frameworks—Next Up: A Joint Roundtable

This statement represents only the first step. On September 5, 2025, the agencies released a strategic follow-up: a joint statement on regulatory harmonization, announcing a public roundtable on September 29, 2025, to align their frameworks further—spanning product definitions, reporting standards, capital requirements, and coordinated innovation exemptions.

SEC Chair Paul Atkins and CFTC Acting Chair Caroline Pham described the session as a pivotal moment to transform U.S. regulatory coordination into a competitive advantage, enhancing clarity and opening the door to financial innovation. Their remarks signal a shared commitment among regulators to make the U.S. marketplace more efficient, innovative, and investor-friendly.

Implications and Forward Outlook

For the crypto industry, this coordinated stance paves a legal path that could bring regulated exchanges into the fold. Institutional venues like Nasdaq, NYSE, CME Group, and Cboe could consider introducing crypto product offerings—once thought off-limits—if they navigate the filing and operational requirements successfully. That is not a “nothing” burger!

Yet, without binding rules or clarified legal definitions, the shape of this new pathway remains uncertain. Regulatory arbitrage and legal ambiguity could persist unless the agencies deliver clear, binding regulations or frameworks.

Conclusion: Cautious Optimism in a Regulatory Renaissance

The joint statement by SEC and CFTC staff marks a meaningful departure from past reluctance—an encouraging signal that the U.S. is repositioning itself as a hub for blockchain-driven innovation. Market participants now have formal permission to explore spot crypto product offerings—if they comply with existing regulatory expectations.

The upcoming September 29th roundtable offers a critical opportunity to transform this gesture into substantive regulatory reality. For firms, token projects, and exchanges, the message is clear: engage early, act boldly, and help shape the evolving regulatory blueprint for the next era of digital asset markets in the U.S.

The Genius Act and Stablecoins: A Game-Changer for Visa and Mastercard?

Yogi Nelson

by Yogi Nelson

Welcome to the BlockchainAIForum

Introduction

Hollywood and Washington, D.C. share a common trait–they both exaggerate! Recently stable coin legislation was passed into law in Washington–our politicians labeled it genius. Is it? Let’s ask that question from the perspective of Visa and Mastercard–the global duopoly of credit cards.

What Is the Genius Act of 2025?

We begin by understanding the Genius Act. The Genius Act, formally known as the Stablecoin Oversight and Innovation Act, establishes a federal regulatory framework for stablecoins—digital currencies pegged to fiat currencies like the U.S. dollar. What does the Genius Act say:

Key provisions include:
– Stablecoin issuers must be licensed by the Federal Reserve or OCC
– Stablecoins must be 100% backed by cash or equivalent assets
– Monthly audits and public disclosures are required
– Consumer protections are explicitly outlined
– Banks and fintech firms can both issue stablecoins under federal supervision

The Genius Act is designed to provide legal certainty, encouraging both institutional adoption and consumer trust in U.S.-based stablecoins. If it succeeds, it might be worthy of its name.

Visa and Mastercard: The Legacy Model

Visa and Mastercard operate on an intermediated model. In essence, they are transaction toll booths, charging a small fee on every swipe, tap, or click.Their core revenues come from:
– Interchange fees charged to merchants for processing credit and debit card payments
– Network fees for facilitating cross-border transactions
– Fraud protection and authentication services

Why Stablecoins Are a Threat

Stablecoins offer a radically different value proposition:
– Instant settlement without intermediaries
– Lower fees—especially for cross-border payments
– 24/7 functionality with no dependence on banking hours
– Programmable money that can enforce rules, automate transactions, or manage subscriptions

With the Genius Act providing legal legitimacy, peer-to-peer payments, retail purchases, and international remittances using stablecoins could bypass traditional credit card rails altogether. This is akin to hotels v Airbnb, taxis to Uber, etc.

Business Model Disruption: The Risk to Visa and Mastercard

1. Revenue Erosion. If merchants and consumers adopt stablecoins for direct payments, interchange and processing fees could decline. Stablecoin transactions—especially over public blockchains—cut out the middleman.

2. Loss of Control Over Settlement. Credit card networks currently manage the full lifecycle of a transaction: authorization, clearing, settlement. Stablecoins shift settlement to blockchain, reducing the value-add of the traditional networks.

3. Emerging Competitors. Startups offering stablecoin wallets, Layer-2 scaling solutions, and DeFi integrations are becoming new challengers. In this environment, Visa and Mastercard may no longer be gatekeepers.

Strategic Response from the Giants

🔗 Integration with Blockchain Rails. Visa has piloted stablecoin settlement on Ethereum using USDC (Circle’s dollar-backed stablecoin). Mastercard has launched its Multi-Token Network to support digital assets.

🤝 Partnering with Crypto Firms. Both have entered partnerships with crypto companies like Coinbase, Binance, and Crypto.com to issue crypto-backed cards and offer fiat-to-stablecoin bridges.

🧾 Tokenized Settlements. Mastercard has explored tokenized bank deposits and blockchain-based remittances, hoping to stay relevant as money goes digital.

💼 Stablecoin Custody and Consulting
Visa and Mastercard could pivot to providing custodial services, stablecoin security layers, or consulting to central banks and financial institutions looking to adopt blockchain

The Cross-Border Payment Revolution

One of the most immediate impacts may be in international payments. Traditional card-based cross-border transactions are slow and expensive. Visa and Mastercard may be forced to rebuild their international payment models around blockchain rails or risk becoming obsolete in this niche. Stablecoins offer instant settlement with minimal fees. Not only do Visa and Mastercard face stablecoin challenges in this area, they must also deal with Ripple XRP and Stellar Lumens XLM.

Expect disruption in:
– Global e-commerce
– Freelancer payments
– Remittance corridors to developing countries

Privacy, Security, and Trust: A Remaining Edge?

Visa and Mastercard still have strong brand trust and robust fraud protection mechanisms. These features matter for both merchants and consumers. Stablecoins must match or exceed these protections to gain widespread adoption. However, if the Genius Act succeeds in establishing a secure and compliant ecosystem for stablecoins, that edge may erode over time.

What the Future May Hold

The Genius Act creates a legal bridge between traditional finance and blockchain-based payments. This opens the door for:
– Direct merchant payments in stablecoins
– Payroll disbursements via crypto wallets
– Loyalty programs powered by tokens
– “Tap to Pay” using stablecoin-enabled apps

If the Genius Act does create that bridge, Visa and Mastercard may need to reinvent themselves as digital infrastructure companies, offering value-added services such as fraud detection, identity verification, and compliance tools for stablecoin-based systems.

Final Thoughts

Visa and Mastercard have spent decades building the infrastructure of global payments. Perhaps they felt secure and comfortable in their duopoly positions. The Genius Act and the stablecoin revolution challenge the very foundation of their model. However, disruption does not necessarily mean extinction. Both Visa and Mastercard have deep pockets and talented staff and are embedded in the financial system. The real test is whether they evolve fast enough to embrace the blockchain-powered future, or whether they will be relegated to legacy status as the world transacts in tokens.

Until next time,

 🏛️ Why Do Crypto Companies Set Up Foundations?

Yogi Nelson

by Yogi Nelson

Welcome to the BlockchainAIForum

In the world of cryptocurrencies and blockchain technology, many of the most successful projects are not run entirely by corporations in the traditional sense. Instead, they are supported by non-profit foundations. Ethereum, Cardano, Polkadot, and Tezos all operate under this model. But why? What purpose do these foundations serve, and why are so many of them headquartered in Switzerland?

🌱 What Is a Crypto Foundation?

A crypto foundation is a non-profit organization established to oversee, support, and promote a blockchain project. These foundations are legally registered entities that act as stewards of the project’s codebase, branding, and community. Unlike a traditional company that prioritizes shareholder returns, a foundation is guided by a mission, such as enabling decentralized finance or supporting smart contract development. Think of it as the moral compass and operations hub behind the scenes.

🧰 What Do Crypto Foundations Actually Do?

Foundations wear many hats, and their responsibilities often include:

👨‍💻 Funding Developers – They allocate grants or directly hire developers to maintain and upgrade the protocol.

📣 Marketing & Community Growth – Foundations run educational campaigns, organize conferences, and promote adoption of the blockchain.

⚖️ Legal and Regulatory Advocacy – They advocate for favorable regulations and help navigate legal challenges.

📖 Governance and Roadmaps – They help shape and coordinate the roadmap of the project, though governance can also be decentralized.

📊 Ecosystem Grants – They fund startups, research groups, and hackathons that build on or support the core protocol.

🔒 Safeguarding Intellectual Property – In many cases, they hold the trademarks and copyrights associated with the project.

🚀 How Do Foundations Help a Crypto Project Grow?

Foundations provide a stable and legal structure that helps a project mature and attract broader participation. Here’s how they contribute to growth:

• Attracting Talent

• Building Trust

• Creating Ecosystems

• Fostering Community

• Serving as Legal Entities

💸 How Are Foundations Funded?

Funding typically comes from two main sources:

🪙 Initial Token Allocations – When the cryptocurrency is launched (through an ICO or other means), a percentage of the total supply—often 5% to 20%—is allocated to the foundation.

🧾 Donations and Grants – Some foundations accept voluntary donations from the community, philanthropists, or crypto-focused VCs.

📈 Strategic Investments – In some cases, foundations hold and invest part of their treasury to ensure long-term financial sustainability.

🇨🇭 Why Are So Many Crypto Foundations Based in Switzerland?

Switzerland, particularly the canton of Zug (aka “Crypto Valley”), has become a hotspot for crypto foundations. I visited and the valley is stunning, but beyond the natural beauty, here’s why:

⚖️ Favorable Legal Framework. Until very recently the USA was hostile to crypto projects.

🔐 Privacy and Financial Stability

🌍 Global Neutrality

🧠 Pro-Blockchain Culture

🧭 Examples: Ethereum Foundation, Cardano Foundation, Web3 Foundation, Tezos Foundation

🧾 Final Thoughts

Crypto foundations serve a vital role in the blockchain ecosystem. They’re not just legal wrappers for projects—they are engines for long-term growth, adoption, and legitimacy.

Until next time,
