Technologies of Web3

Technologies of Web3

Web3 is a platform that utilizes the features of all the future technologies, like blockchain, AR, VR, and so on, to develop decentralised applications (dApps) and enhance the user experience immensely.

Let us have a look at the technologies of Web3 here:

Infrastructural Technologies of Web3

Among the multitude of technologies leveraged in Web3, the most basic and critical are the ones used at the foundational level, i.e., the technologies that establish the whole structure of Web3. A few examples of Infrastructure Technologies are:

  • Blockchain Technology: A decentralised and distributed peer-to-peer digital network that facilitates and stores online transactions in several databases, discouraging data manipulation.
  • Crypto mining: It is the technology that allows the participants’ computers to solve complex math problems and earn virtual digital cryptocurrencies like Bitcoin, Ethereum, Dogecoin, etc., for verifying and authorising the transactions on their blockchain network.
  • Distributed Networks: Here, a bulk of tasks can be distributed among other networks to process it fast while sharing the related information among each other easily.
  • AR/VR/XR: Augmented Reality (AR) and Virtual Reality (VR) are cumulatively called Extended Reality (XR). Using eye wearables, the virtual objects will feel like real objects in 3D to our senses. 
  • Cumulative Computing: In this, a complex task will be broken down into simple problems and distributed to other computers in the network to solve it fast and easily.
  • Non-Fungible Tokens (NFTs): These are the encrypted virtual tokens that refer to a unique digital symbol, object, asset, image, art, and so on, that can’t be replaced with something else or its copies.
  • Edge Computing: This is a decentralised and distributed network to store and compute the user data near them in the local edge servers only.

Protocol-based Technologies of Web3

  • Consensus-based Algorithms: In a blockchain network, a consensus-based algorithm in which all the blockchain participants agree to the present state of a distributed ledger by reaching an agreement.
  • Side-Chains:  This technology allows connecting a separate blockchain network with a separate consensus protocol to connect to the main blockchain network. This is done to ease out the congestion in the main blockchain while ensuring data security and privacy.
  • Blockchain Virtual Machines: It is a blockchain algorithm program that mimics the processes of a computer, i.e. it has a virtual CPU, memory, and storage just like a computer and functions just like it.

Examples: Ethereum 1.0, Wanchain, Hashgraph, Ethermint, Solana, Cardano, and many more.

Utility Technologies

  • Multi-Signature: This is a smart contract where the agreement of the majority of participants is a must for transacting assets from the wallet. It ensures divided ownership among the participants.
  • Virtual Blockchain Wallets:  A blockchain wallet is the same as a digital wallet, but it deals with cryptocurrencies, and in this, you can withdraw and encase your invested currency to store in another wallet.
  • Digital Assets: It trades the unique virtual representation of any kind of physical assets, enhances its liquidity, and buys or sells them fast, with low transaction costs.

Services Technologies

  • Data Feeds: It delivers live and fasts trade or transaction data among the crypto markets. Example: Cryptocurrency Data Feed
  • Off-Chain Transactions Computing: Here, the cryptocurrency transaction is moved out of the blockchain by either making an agreement among the involved parties, by having an intermediary guarantor, or by exchanging the asset with a coupon, thus, reducing transaction costs.

Pros and Cons of Web3 Technology

Pros and Cons of Web3 Technology

Pros of Web3 Technology

Let us take a look at the top 11 Benefits of using Web3 technology:

  1. Privacy of data by giving data control in the hands of the users.
  2. Enhance data security and resists censorship of free transparent information by disallowing data manipulation.
  3. It removes the authority of intermediaries like banks, insurance agencies, and governance institutions.
  4. Transparency of data transactions.
  5. Efficient browsing with efficacy in search results.
  6. Enhanced user interaction with the web world.
  7. Free flow of data as distributed nodes gives uninterrupted services.
  8. Personalised solutions to search queries.
  9. Beneficial to artists, creators, and advertisements and marketing industries.
  10. Improves work productivity.
  11. New and better career opportunities with the opening of new technological avenues.

Cons of Web3 Technology

As it is always good to know the negatives of any upcoming technology, let us have a look at them here:

  1. Web2 apps will become obsolete as non-blockchain-based gadgets and apps may have less usability.
  1. Tough to understand and use, i.e., other than Gen-Z kids, older generation users may find it difficult to comprehend these technologies.
  1. It takes away the right to be forgotten from the users, as you can’t edit data without verification by most users on the network.
  1. Lack of strong privacy laws and policies.
  1. Not environment-friendly. The multitude of electronic gadgets will increase the carbon footprint.
  1. Web3 technologies are not yet ready to be adopted by old-style businesses. 
  1. Also, technological errors and user-side difficulties discourage its use in the current scenario.
  1. Menace of hacking, money laundering, terrorism, etc.
  1. The more immersive the technology, the more addictive it is. Web browsing time will skyrocket due to this.
  1. It could be disastrous for mental health.
  1. It may threaten the existence of our economy and civilisation if AI/ML-based machines take over the human mind.

How Web3 Technology will Change the World?

How Web3 Technology will Change the World

The decentralisation revolution in network technologies is the best natural evolution humans could experience. Earlier, a few tech behemoths were accumulating user data and exploiting it for their growth.

Now everyone can earn virtual currency and share profits to verify the authenticity of transactions online. The data control will come back to the hand of the user. The feature of interoperability between platforms will bring a completive environment to the mega-giant companies.

The decentralised blockchains are going to strengthen digital property rights. On the other hand, it will open up endless job opportunities, and that too remote work.

In a way, Web3 will affect the lives of everyone on the internet. We must prepare ourselves to smoothly transition from Web2 to Web3 soon enough.
