In our first edition, we explored the digital wallet as your gateway to self-sovereignty. Now, we expand that horizon to understand the ecosystem this gateway opens up: Web3.

While "crypto" is often associated with financial speculation, the true revolution lies in how this technology rebuilds the internet and physical infrastructure to empower the individual. This edition breaks down Web3, the rise of Decentralized Physical Infrastructure Networks (DePIN), and how networks like Nodle are disrupting legacy systems with real-world utility.

The internet has evolved through distinct eras, each solving real problems while introducing new ones.

The early internet was fundamentally static. Websites displayed fixed content that users could read but not modify. Individual website owners hosted their content on their own servers without needing permission from giant corporations. This decentralization came at a cost: building websites required technical expertise, navigation was cumbersome, and the experience was fragmented.

Broadband and cloud computing enabled a radical shift. Companies like Google, Facebook, Amazon and YouTube made content creation and sharing frictionless. Anyone could start a blog, upload videos or post thoughts without technical knowledge.

But this convenience had a hidden price. A handful of mega-corporations now controlled the digital landscape. When you used these services, you surrendered your data. Every search query, click and minute spent scrolling was recorded, analyzed and sold to advertisers. Your data became the product. Algorithms determined what you saw, and platforms could unilaterally change their rules, ban your account or demonetize your content. Users became locked into platforms. Your social graph, reputation and digital identity all lived on someone else's servers.

Bitcoin (2009) and Ethereum (2015) created a new primitive: decentralized networks governed by code, not corporations. Applications now run on blockchains - distributed networks where thousands of independent computers collectively maintain the system. No single company owns the network. Your data lives on a distributed ledger that is cryptographically secured and transparent.

This enables revolutionary changes. You hold the private cryptographic keys to your digital assets, identity and data. Web2 requires trusting corporations won't misuse your information or change the rules. Web3 eliminates that need by replacing trust with code and cryptography. You verify transactions yourself. There is no single point of failure. Web3 protocols include tokenomics - native currencies that incentivize participation, ensuring value flows directly to contributors. Applications can compose with each other like building blocks. Your wallet works with any dApp, and your identity can follow you across platforms, standing in sharp contrast to Web2's walled gardens.

Web3 still faces real challenges: transaction fees can spike during network congestion, regulation remains unclear, the learning curve is steep for non-technical users and security risks persist for those who aren't vigilant with their keys.

Technologists are already thinking about what comes next. Web4 would integrate Web3's decentralization with artificial intelligence, the Internet of Things (IoT), augmented reality, and autonomous agents. Autonomous AI agents could independently perceive environments, make decisions, and execute complex transactions without human intervention. The physical and digital worlds would merge completely - IoT sensors embedded everywhere, continuously gathering data. Augmented reality would overlay intelligent information onto the real world.

This raises critical questions: Will decentralized infrastructure and AI lead to genuine distributed power, or will new forms of concentration emerge?

One of the most powerful applications of Web3 is DePIN (Decentralized Physical Infrastructure Networks). Traditionally, building infrastructure like telecom networks, maps or sensor grids required massive corporations or governments to spend billions on hardware and maintenance. DePIN flips this upside down by crowdsourcing infrastructure through token incentives.

Nodle is a prime example. Instead of building cell towers, Nodle leverages the billions of smartphones already in existence. By running the Nodle app, your phone becomes a "node" in a global network, using Bluetooth to securely connect and locate smart devices nearby.

DePIN shifts users from passive consumers to active network partners. In Nodle, this happens on two levels.

The world around us is filled with devices emitting signals - like BLE beacons from headphones or smart tags - broadcasting information like UUIDs or sensor data. Usually, this data disappears into the void. When you install the Nodle app, your smartphone becomes an "Edge Node" that rescues this data. It picks up these signals and adds a timestamp. Crucially, because Bluetooth enables highly accurate positioning, the app calculates and transmits the precise location of the beacon itself, not just the smartphone's general location. This package is securely uploaded to the cloud where it is anonymized and formatted for machine reading.

Advertising Payload format on BLE

This blog is to describe more details on the advertising payload. The Packet data unit for the advertising channel (called the Advertising Channel PDU) includes a 2-byte header and a variable payload from 6 to 37 bytes. The actual length of the payload is defined by the 6-bit Length field in the header of the Advertising Channel PDU.

The process adheres to strict compliance guidelines like GDPR: all data is anonymized, and any unused or unrequested data is discarded after a set period, following industry best practices for data privacy and security. If a subscriber has registered a specific device and your phone's data matches it, a Smart Mission automatically triggers a reward event. By simply keeping the app running, you provide the Proof of Connectivity that powers this global digital fabric.

As the network grows, opportunities shift from simply being present to doing something specific. Smart Missions are programmable jobs deployed on the blockchain by paying customers.

A customer like Roole (a major French automobile club) needs to find a stolen car equipped with a Bluetooth tag. They create a Smart Mission on the blockchain containing the target tag's cryptographic ID, a bounty pot of tokens locked in a Smart Contract and the condition "Pay this bounty to the first node that provides a verified location for this ID."

The Smart Mission is registered. The Nodle app's continuous background scanning already captures all Bluetooth signals in the environment. When one matches the specific tag ID from the mission, the data your phone collected - timestamp, location, signal strength - becomes relevant.

You're walking down the street when your phone's Bluetooth radio detects the specific tag ID. The app securely encrypts this location data and signs it with your wallet's key, transmitting this Proof of Connectivity to the blockchain.

The Smart Contract automatically verifies two things:

Is the data valid? Yes, the signature matches.

Is the mission active? Yes, the car is still missing.

The contract executes, unlocking the bounty and transferring it directly to your wallet. The subscriber gets the car's location, and you get paid instantly - all without actively searching for anything.

This model creates a decentralized gig economy. As more subscribers join - logistics firms tracking pallets, cities monitoring air quality sensors, brands authenticating photos - the number of Smart Missions increases. What starts as earning pennies for passive coverage evolves into a dynamic marketplace where your device constantly monitors the environment, matching captured data against active missions, and fulfilling rewards in the background. Your daily movement becomes a stream of passive income.

But Smart Missions aren't limited to locating lost assets. The same infrastructure that powers decentralized asset tracking also powers something equally important: preserving the authenticity of our shared reality. Every photograph you capture and verify with the Click Camera, becomes part of an immutable historical record.

In an era of deepfakes and AI-generated misinformation, proving what is real has never been more critical. Click, a camera app powered by Nodle, uses Web3 technology to transform every user into a trusted witness of reality.

The Problem:

On Web2 platforms, photos are easily manipulated and their origins stripped away. You have no guarantee of when, where or by whom a photo was taken. This fuels misinformation and erodes trust everywhere - from news to product reviews.

The Solution:

Click uses the C2PA standard (Coalition for Content Provenance and Authenticity) adds a manifest with all metadata to the image, which is then cryptographically signs photos the instant they're captured. This creates an immutable chain of custody recorded on the blockchain. Global media group Vivendi already uses Click Certify to authenticate press releases and business documents, ensuring journalists and investors can irrefutably verify a document's origin without needing a central authority to validate it.

Every Click photo - whether it's a sunset, a cat, a historic building or a street mural - becomes a permanent, cryptographically verified record of that moment in time and space. These aren't just personal memories anymore. They're contributions to preserving authentic history on the blockchain. As billions of verified images accumulate across the Nodle network, we build a decentralized archive of reality itself, accessible to anyone and verifiable by everyone.

Click's integration with Nodle's Smart Missions amplifies this impact. Users become verified reporters or data collectors, earning by capturing and authenticating the real world.

The power of Web3 lies in its ability to disrupt inefficient monopolies while complementing existing systems. By using smartphones we already own, Nodle removes the need to manufacture and deploy millions of new hardware sensors, reducing electronic waste and capital expenditure. Solutions built on Nodle don't replace existing institutions - they provide actionable, high-precision data that helps them do their jobs more effectively. Event planners don't replace their professional crews; they gain additional perspectives. Scientists don't abandon fieldwork; they supplement it with crowdsourced data.

Web3 is more than a new financial system; it's a valuable complementary layer that fills infrastructure gaps where building and maintaining centralized systems is prohibitively expensive. DePIN enables services - global asset tracking, worldwide sensor networks, decentralized data collection - that would otherwise be economically unfeasible for any single corporation. Rather than replacing the centralized internet, Web3 extends it with capabilities that were previously impossible.

Whether authenticating a news story with Click, helping recover a stolen car through Roole, updating a sensor's firmware on the fly across the Nodle network, or simply providing connectivity in exchange for rewards, the technology is finally delivering on its promise: utility that empowers the individual and serves the community.

The future isn't about getting rich quick with crypto. It's about building decentralized infrastructure that solves problems centralized systems cannot, ensuring that the value created flows to the people who actually built it.
