By the end of 2024, the total size of CeFi loans will be US$11.2 billion, down 68% from the historical peak in 2022. Alex Thorn, head of research at Galaxy Digital, said in an article on X that based on a review of public documents, bankruptcy documents, and voluntary disclosures by active lenders, by the end of 2024, the total size of centralized finance (CeFi) loans was $11.2 billion, down 68% from the historical peak (ATH) of $34.8 billion in 2022. By the end of 2024, the largest CeFi lenders by outstanding loan book size were: Tether, Galaxy, Ledn, Coinbase, Maple, Unchained, Centrifuge, Goldfinch, Arch, and TrueFi. While DeFi is fairly transparent, CeFi lending is more opaque. However, when combined, the outstanding loan market size is about $30 billion. Today, the outstanding loan market size of DeFi has surpassed CeFi. If you add in collateralized debt position (CDP) stablecoins such as DAI, the size will exceed $35 billion. In fact, DeFi currently accounts for more than 60% of the cryptocurrency lending market.

--- $ETH --- What Exactly is Ethereum? Imagine if the internet could run itself—no middlemen, no centralized servers, and full control in your hands. That’s the idea behind Ethereum. Ethereum is a blockchain platform that allows developers to build smart contracts and decentralized applications (dApps). Unlike Bitcoin, which is mainly digital money, Ethereum is more like a global computer—a place where code runs without being shut down, censored, or tampered with. Launched: July 30, 2015 Native Coin: Ether (ETH) Inventor: Vitalik Buterin Consensus Mechanism: Proof of Stake (as of 2022) --- The Vision Behind Ethereum Vitalik Buterin, a young Canadian-Russian programmer, felt Bitcoin was too limited. He wanted a blockchain that could support a wider range of applications. So he co-founded Ethereum to be programmable—letting people build everything from games to financial tools on the blockchain. Ethereum’s mission? To become the foundation for a decentralized internet (Web3). --- How Ethereum Works 1. Smart Contracts Smart contracts are lines of code that execute automatically when conditions are met. No trust needed. No third party. Just pure automation. Example: A decentralized insurance contract that pays out if a flight gets delayed—without needing an insurer to approve it. 2. Ethereum Virtual Machine (EVM) This is the heart of Ethereum. The EVM runs all the smart contracts and makes sure they work the same way everywhere. 3. Ether (ETH) ETH is used to: Pay for transactions (called gas) Stake and earn rewards as a validator Power apps and smart contracts --- Ethereum’s Major Shift: The Merge In September 2022, Ethereum underwent The Merge, switching from Proof of Work (PoW) to Proof of Stake (PoS). This was a massive upgrade that: Cut energy usage by over 99% Introduced staking, where validators lock up ETH to secure the network It was like replacing a rocket engine mid-flight—and it worked. --- Why Ethereum Matters Ethereum is the backbone of almost everything cool happening in crypto: DeFi (Decentralized Finance): Trade, borrow, and earn without banks NFTs: Digital art, collectibles, and in-game assets DAOs: Online communities running like co-ops with shared ownership Stablecoins: Like USDC and DAI, pegged to the dollar but running on-chain All of this lives on Ethereum or is inspired by its architecture. --- Strengths of Ethereum Flexible and Programmable: You can build almost anything on it.
