What is Centralized Finance (CeFi)

Centralized Finance (CeFi) refers to cryptocurrency financial services lending, borrowing, savings, trading, and yield generation offered by centralized companies that maintain custody of user funds and operate under traditional business and regulatory structures. CeFi is positioned between traditional finance (TradFi) and fully decentralized finance (DeFi).

WHAT CEFI OFFERS

Crypto Lending: Users deposit cryptocurrency with a CeFi platform and earn interest. The platform lends these funds to institutional borrowers and retail margin traders. BlockFi, Celsius, and Nexo were prominent examples.
Crypto Borrowing: Users pledge cryptocurrency as collateral and borrow fiat or stablecoins useful for accessing liquidity without selling appreciated crypto.
Crypto Earn Accounts: Fixed or flexible savings products paying APY on crypto deposits competing with traditional savings rates.
OTC Trading: Large-volume trades executed directly with the exchange's trading desk, outside the public order book.
Fiat Services: Bank-integrated products allowing seamless conversion between fiat and crypto.

CEFI VS. DEFI

Custody: CeFi holds your funds (custodial). DeFi is non-custodial you control your private keys.

Accessibility: CeFi requires KYC and sometimes minimum deposits. DeFi is permissionless anyone with a wallet can participate.
Regulation: CeFi operates under financial regulations. DeFi protocols are code-governed with no legal entity.
Speed of Innovation: DeFi moves faster; CeFi offers more familiar interfaces and customer support.
Risk Profile: CeFi carries counterparty/insolvency risk. DeFi carries smart contract and oracle risk.

THE 2022 CEFI COLLAPSE

The dramatic failures of Celsius Network, BlockFi, Voyager, and ultimately FTX in 2022 exposed the systemic risks of CeFi specifically the misuse of customer funds for proprietary trading and the lack of transparency in reserve management. These collapses caused billions in user losses and accelerated interest in self-custody and DeFi alternatives.

SURVIVING CEFI PLAYERS

Exchanges with earn products (Binance Earn, Coinbase), regulated lenders, and compliant OTC desks continue to serve institutional and retail users who prefer the familiarity of centralized services.

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.
