Security, Privacy, and Ethics in the Web 3.0 Era

Web 3.0, which commonly refers to the technological trends around blockchain and NFTs, is not a substitute for today's Web 2.0 technology (yet). But the trend clearly changes what "literacy" means on the internet, and the new wave requires individuals to have a different mindset.

When people say Web X (X = 1.0, 2.0, 3.0, ...), I personally see X as an indicator of how the physical and digital world are strongly tied to each other; Web 1.0 represents the traditional static websites that were normally treated as a "separate world", whereas Web 2.0 & 3.0 focus more on dynamic user-generated contents that have a direct impact on our day-to-day life.


Our life is supported by the internet at a different level of technological complexity, and as X increases, the norms of real-world societies (e.g., moral and law) become more important to ensure the things comply with security, privacy, and ethics standard. That is, when we publish or consume something on the internet, it is important to have a required level of literacy not to misuse the technology and not to be manipulated by malicious actors.

Here, the level 3 (Web 3.0) is all about decentralization, which:

  1. strengthens the relationship between digital and physical concepts/events;
  2. values individual's autonomy;
  3. changes their incentive model.

Meaning, the role and responsibility of individuals become bigger. Therefore, to support safe & fair adaptation of the technology, "regulation" would play a more important role than it used to in Web 1.0 and 2.0. In fact, you might have heard from people in the NFT communities saying "the regulations haven't caught up with the new technology yet". We have to see how quickly the discussion progresses.

Even though it sounds complicated and challenging, we'd eventually need the corresponding literacy anyway. So, does that mean we need to learn more about the new technologies ASAP e.g., at K-12 education level? Not necessarily. The good news is, at least for now, Web 3.0 is more like a buzzword, and the majority of our life can still be supported by 2.0 (or even 1.0) technology.

Importantly, blockchain is just a tool, and we must focus on a problem itself first and foremost. We should not decentralize the applications for the decentralization sake, as I learned from University at Buffalo's blockchain courses:

they emphasized how focusing on a problem is important for us to apply blockchain techniques. [...] Just like the other advanced techniques (e.g., machine learning), blockchain is not a silver bullet that can resolve arbitrary problems.

There must be real human beings beyond the distributed computing nodes, and hence interacting with the technology with a proper degree of complexity with a corresponding literacy (security, privacy, and ethics) level is critical. It is particularly true after Web 3.0 largely expanded the possibility of applications, but we haven't done a good job even for Web 2.0 yet; unfortunately, the developers have kept leaving a huge room for improvement in the context of ethical product development for the last decade. Starting from a problem (i.e., user's voice)—It is always the foundational step to take.
