Web3: business value and challenges


Even when it is yet to see if Web3 will be the next internet revolution in this new wave of distribution, perhaps my preference would be to see it from another angle, which is that Web2 and Web3 coexist, bringing the best cases from the centralization and decentralization universes delivering the ideal internet solutions.

So,  what is Web3, and what is the difference with Web2?

The term Web3 came from Ethereum co-founder Gavin Wood, and it refers to a decentralized online ecosystem based on blockchain. If you have been reading about cryptocurrency, tokens, and blockchain then you have been learning about Web3.

 Web2 term has been introduced for describing the current landscape related to a more centralized technologies controlled by, what some may call, “Big Tech” organizations, such as the social-based ones like Meta (Facebook); but also including Google, Netflix, Amazon, Microsoft, companies in the FinTech space, etc.


dApps, which is the abbreviation for decentralized applications, are programs or digital apps that run on either blockchain or a peer-to-peer network of computers. These applications are essentially decentralized to a great extent and cannot be controlled by a single authority.

Web3 business value

  1. More control for the consumer. Users own their data, having the liberty to share it or keep it private
    Less surveillance by the companies. 
  2. Smart contracts and NFTs can be used to connect directly to the owners of their work
  3. It is to assume that web3 technologies could be more stable and accessible due to their decentralization and distribution.
  4. Decentralization applications can host unlimited number of participants on both sides of any transaction



What is Proof of Work?

Proof of work ( PoW) is a form of cryptographic proof in which one party (the prover) proves to others (the verifiers) that a certain amount of a specific computational effort has been expended.


What is Smart Contract?

Smart contracts are simply programs stored on a blockchain that run when predetermined conditions are met. They typically are used to automate the execution of an agreement so that all participants can be immediately certain of the outcome, without any intermediary’s involvement or time loss. They can also automate a workflow, triggering the next action when conditions are met.

Some of the challenges with Web3

  • Harder to moderate and filter content, giving a window to cybercrimes, hate speech, and misinformation.
    Scalability. Web3 is slower due to the P2P.
  • Web3 uses more computing power, which means the need for more energy. This implies a higher carbon footprint. 
  • Accessibility is an issue as due to the gap with the integration into the modern web browsers

Closing remarks

While some may say that Web3 is the future of the internet, in an uncensored world, I believe that the future lies in the middle that has the right balance between the Web2 and Web3 space.

What it means to be product led

Many successful organizations including Miro, Figma, Spotify, Atlassian are using products as vehicles to drive customer acquisition and growth. These organizations use their products at the centre of their strategy to win customers and retain them.    Photo by Miguel Á. Padriñán via Pexels If you use any of these tools you are aware of the free trials and freemium versions of these products. These organizations use free versions to generate prospects, drive adoption and convert to paying customers. These organizations are always customer focused and drive to provide friction-less customer experience.  Recently I learned about the inner workings of these organizations by taking the course from Mind your Product and Pendo . Currently the course is available for free and I recommend signing up for the course while the offer is available. Please find the details at the end of the post.  I found the course very insightful and I summarized three (3) key pillars of being a product led organ

The Creative Process

By: Herak Sikder I still remember the day I watched “ Finding Nemo ” for the first time. I was feeling bored and wanted to watch something to pass my time. I assumed Finding Nemo to be one of those animated movies that you just watch once and then forget. But soon after I started watching the movie I was totally absorbed by its storyline. It almost felt like I was watching a real life story unfolding in front of my eyes and all the characters seemed to come alive. That was the first time I experienced the movie making magic of Pixar and till this date Pixar movies have not failed to amaze me whether it’s Toy Story, Cars, Monsters Inc., Ratatouille, Up, Wall-e and many more. So I was really excited when I found out that ED Catmull , one of the cofounders of Pixar released his book. I picked up the book from Indigo upon it’s release and I was wasn’t disappointed. Ed tackles a lot of common issues that plagues successful organizations as they expand fast and lose their innov

Designing Habit Forming Mobile Application

Mobile Applications have become an integral part of our daily lives - we use mobile apps as alarm clocks to wake us up in the morning, to create to do lists when we start our day, to communicate with our colleagues at work via apps like Skype. We even check reviews of restaurants to visit on apps like Yelp and we seek entertainment on apps like Netflix and spotify. So what drives us to use these apps so seamlessly in our daily lives? Why we prefer some apps over others? Is there a science behind designing successful mobile apps like Facebook?  Photo by Peter C from Pexels A study in US revealed that a user between the age of 18 and 44 visits the Facebook app on average 14 times a day [1]. This shows that using the Facebook app is a daily routine for many of its users. This makes Facebook a great example of a habit forming mobile app which is designed with human psychology in mind that encourages habit forming behavior in its users .   I recently attended a seminar on the de


Driving Digital Strategy The book " Driving Digital Strategy ", by Sunil Gupta , came at the right time as I have been studying many aspects of the business transformation and the disruption that is happening across the different industries. In this era, as a company leaders, just doing what brought you to this present, not embracing change, not renewing yourself, and important aspects of your business; is an indication that your ego, or comfort, or your fear to change, is not allowing you to move forward... and that potentially will be the "end". That "end" can come in one year, two... perhaps five years... but make no mistake, it is coming. The introduction of this book have key notes that I found extremely relevant to my current research. One of them being the following: "The leaders who achieve 'transformative' results go all-in on digital. That is they don't treat digital strategy as separate from their overall strategy.
