What is Digital Rupee (e₹ / CBDC)

The Digital Rupee (e₹) is India's Central Bank Digital Currency (CBDC) — a digital form of the Indian Rupee issued and backed directly by the Reserve Bank of India. Unlike commercial bank deposits or UPI transfers, which are claims on private banks, the Digital Rupee is a direct liability of the RBI — equivalent to holding physical cash in digital form. RBI'S CBDC MANDATE The Finance Minister announced India's CBDC in Union Budget 2022. The RBI launched pilots in 2022-2023 to test the technology and understand usage patterns before a full rollout. The goals: Reduce cash handling costs. Enable programmable payments (conditional disbursements, government transfers). Provide a digital currency option that doesn't rely on private bank intermediaries. Maintain monetary sovereignty in an increasingly digital payments environment. TWO CBDC PILOT TYPES Wholesale CBDC (e₹-W): Launched November 1, 2022. Designed for interbank settlement and government securities transactions. Participants: Select commercial banks. Uses: Settling inter-bank transactions in digital rupees rather than maintaining physical settlement accounts. Retail CBDC (e₹-R): Launched December 1, 2022 in select cities. Designed for general public use — the everyday digital currency. Users hold e₹ in a digital wallet provided by participating banks. Transactions are peer-to-peer, direct, and offline-capable (unlike UPI, which requires internet connectivity). HOW DIGITAL RUPEE DIFFERS FROM UPI AND CRYPTO vs UPI: UPI is a payment rail for transferring existing bank deposits. e₹ is actual money (RBI liability) in a wallet. UPI requires bank account; e₹ wallet can work without one. vs Crypto: e₹ is centralised, permissioned, and issued by the government. Price is fixed (₹1 = 1 e₹ always). No price volatility, no investment use case. CURRENT STATUS AND ROLLOUT RBI conducted retail pilots across 13 cities and 9 commercial banks by 2024. Transaction volumes remained modest — digital India already has UPI dominance. RBI has expressed intent for broader rollout with offline functionality prioritised for rural and low-connectivity areas.

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.
