Without further ado, let’s begin.

What is Web3 Banking?

Web3 Banking defines the use of web3 technology, including blockchain, cryptocurrency, smart contracts, NFTs, DAOs, and more, for conducting banking-related operations. It makes the most of blockchain technology that allows users to leverage cross-border payments.

This technology applies the decentralized blockchain-based principles to financial services. Web3 banking combines the decentralized internet with financial services to let you control your own assets.

Let’s understand it from the base:

Web1: Only read, where users cannot interact with the website. Here, websites are made with HTML and CSS.

Web2: Read and write; here, the internet offers users a platform for interaction. Here, modern platforms such as Facebook and Twitter allow you to connect with the end users.

Web3: Read, Write, Own. This is the new internet of value; here, the decentralized network is integrated.

Web3 banking technology explained: A simple breakdown

Web3 banking is the use of blockchain, smart contracts, and decentralized protocols for delivering banking services.

• Decentralization: Web3 banking technology drives decentralization by replacing financial intermediaries with blockchain technology. Here, the data is distributed across a network for resilience and user control.
• Blockchain Technology: Web3 banking replaces traditional, centralized databases with blockchain technology to offer financial services. This technology offers a transparent, immutable ledger by enabling trustless interactions.
• User Empowerment: The implementation of Web3 technology in banking offers decentralized financial services, which means it offers users the ability to control and manage their finances successfully.

How Does Web3 Technology Differ from Web2 Technology?

Web3 technology differs from Web2 technology through the way it offers decentralization. Web2, known as the interactive and social web, focuses on user-generated content and usability. Web2 technology is dominated by tech giants such as Google, Meta, and Amazon that act as intermediaries to store your data on centralized servers.

However, Web3 technology uses blockchain technology, distributes control across a peer-to-peer network, and allows you to own and control your digital assets.

Blockchain in banking allows banks to cut transaction costs and minimize the settlement times from days to minutes for cross-border transactions.

Before you opt for the Web3 banking system, are you aware of how it works?

Well, if not, then let’s evaluate it all in the following section.

How Does Web3 Banking Work?

Web3 banking replaces traditional banking intermediaries with decentralized networks. This all begins with creating a digital wallet, operating on a decentralized peer-to-peer (P2P) model rather than relying on central servers.

Let’s evaluate the complete working process of Web3 Banking below:

Step 1: Technologies Form the Foundation

This platform uses the latest technologies related to blockchain, smart contracts, crypto wallets, and decentralized protocols to form the foundation and replaces the centralized servers on which traditional banks depend.

Step 2: Users Get a Wallet and Verified Identity

Now, the users create their account or a crypto wallet that holds all the private keys, and then they complete the identity verification via DID. This is the step where the Web3 technology is reusable across platforms without any repeated KYC.

Step 3: Build a Fiat-to-Crypto Bridge

The user deposits fiat or crypto. On-ramp infrastructure converts it into stablecoins or tokenized assets so it can move on-chain while the app still functions like regular money.

Step 4: Smart Contracts Execute the Transactions

When the user sends money, borrows, or even invests, smart contracts automatically function effectively and carry out the actions based on the pre-set rules, with no manual approval and with no intermediary needed.

Step 5: Transaction Is Verified

Now the transaction is verified as the network validates the transaction and records it permanently on the blockchain. AI-powered monitoring simultaneously scans for fraud risks in real time.

Step 6: Near-Instant Settlement

Later, the funds are settled instantly in days, without any requirement os clearing house. This is the step under which confirmation related to the transaction is received. Here, the users retain full control of their funds.
