What is FinTech

FinTech (Financial Technology) refers to the use of innovative technology to deliver financial products and services more efficiently, accessibly, and affordably than traditional financial institutions. FinTech encompasses everything from mobile payment apps and digital banking to robo-advisors, peer-to-peer lending, and blockchain-based cryptocurrency representing the most significant transformation of the financial industry since the invention of the credit card.

THE FINTECH SPECTRUM

FinTech is a broad category spanning multiple sub-sectors:

Payments and Transfers: PayPal, Stripe, Razorpay, UPI-based payment apps (PhonePe, Google Pay, Paytm) digital payment infrastructure.

HOW CRYPTO FITS INTO FINTECH

Cryptocurrency and blockchain represent the most radical wing of FinTech attempting not just to improve existing financial services but to rebuild them entirely on decentralised infrastructure. DeFi replicates banking without banks. Stablecoins enable instant cross-border payments without SWIFT delays. NFTs create new ownership and monetisation models. CBDCs represent governments' FinTech response to crypto.

INDIA'S FINTECH ECOSYSTEM

India has emerged as one of the world's leading FinTech markets: UPI processes over 10 billion transactions per month. Fintech unicorns including Razorpay, PhonePe, Paytm, and CRED have attracted billions in investment. India Stack (Aadhaar, UPI, DigiLocker) provides the digital infrastructure. The RBI's Digital Rupee (e-INR) is India's CBDC initiative. Indian crypto exchanges including CoinDCX and WazirX are FIU-IND registered.

Terms in addition to the FinTech

Blockchain

A blockchain is a subset of a distributed database. The Bitcoin inventors originally prototyped the system in 2008. This modern database is made up of separate blocks that are connected together in a chronological chain. Blockchains may be used to store a wide range of data types. It has mostly been utilized as a public ledger for bitcoin transactions to date. A peer-to-peer network comprised of independent nodes uses a consensus process to ensure the blockchain's security and legitimacy. Each node in the network keeps a public and immutable copy of the data.

2 Factor Authentication (2FA)

2 Factor Authentication is a security measure with two layers. It is used by the majority of cryptocurrency exchanges. To log in, you must provide not only a password, but also a code obtained, for example, from the Google authenticator.

Airdrop

An airdrop is a method of distributing coins. End users can typically obtain coins for free or in exchange for doing a small task, such as subscribing to a newsletter, sending a tweet, or inviting others via a personal affiliate link. Cryptocurrency airdrops — the act of depositing cryptocurrency into public crypto wallets — are utilized as a marketing, liquidity creation, and network bootstrapping technique for many different types of blockchain initiatives.

Altcoin

Altcoin - "alternative coin" - is any kind of digital currency other than Bitcoin. Since the launch of Bitcoin, the world's first digital currency, many altcoins (as well as supporting blockchains) have been created. Altcoin digital currencies share many similarities to Bitcoin, but consistently and have significant differences. There are about 20,000 altcoins, and this number is expected to grow significantly in the coming years. Altcoins often develop Bitcoin features. Ethereum, currently the most widely used blockchain, supports digital contracts and separate applications where Bitcoin does not. Altcoins are also often created to cater to the needs of different users. The Litecoin blockchain, for example, can process payments quarterly for the duration of Bitcoin.

Cold Storage

Cold storage is the way to store cryptocurrency offline. The word refers to the use of offline wallets that are not connected to the internet. Cold storage is the most secure way to keep cryptocurrencies since an offline currency becomes less likely to be hacked and stolen. Paper wallets, printed renditions of private keys, and offline hardware and software wallets are all examples of cold storage.
