Chapter 1: What is CeDeFi?

CeDeFi, a blend of centralized finance (CeFi) and decentralized finance (DeFi), promises to enhance transparency, spur innovation, and broaden accessibility in finance. Let's delve deeper into this concept.

Neither centralized exchanges (CEX) nor decentralized exchanges (DEX) have successfully integrated sovereign identities (SSI) into their frameworks. The question remains: Can CeDeFi truly revolutionize the financial sector?

As digital transformation accelerates, financial services are increasingly confronted with challenges surrounding security, control, and transparency. Consequently, decentralized finance projects have caught the eye of users seeking more democratic oversight over their financial dealings.

In September 2020, Binance Smart Chain (BSC) was introduced as a fully programmable alternative to the Binance Chain, enabling smart contracts from the start. As DeFi began thriving on Ethereum while Binance DEX struggled for traction, Binance identified a critical missing feature: the ability to execute smart contracts and allow other teams to create their applications.

To address this, Binance made a strategic choice. Rather than modifying the existing Binance Chain to include smart contract capabilities—which would have compromised performance—they opted to create a parallel chain, leading to the birth of Binance Smart Chain.

Creating a brand-new smart contract platform from the ground up typically requires extensive research and development time. Instead, Binance capitalized on the familiarity users and developers had with Ethereum by forking Ethereum’s Go client. However, merely forking Ethereum wouldn’t suffice; thus, Binance optimized the new chain for lower fees and enhanced transaction speeds, albeit at the cost of decentralization and censorship resistance.

This optimization involved replacing Ethereum's Proof-of-Work consensus mechanism with a Proof-of-Staked-Authority model and adjusting parameters like block time and gas limits.

The Scalability Trilemma, a concept introduced by Vitalik Buterin, highlights the trade-offs inherent in blockchain architecture. Each blockchain must navigate three fundamental attributes: security, scalability, and decentralization, which cannot all be maximized at once. Improving one often necessitates sacrificing another.

Sharding, an approach chosen by Ethereum, attempts to solve this issue by dividing a blockchain into smaller segments known as shards. However, even sharded blockchains struggle to handle extreme transaction volumes without compromising decentralization and security.

This is why the Ethereum community has turned to Layer 2 solutions, which aim to enhance scalability without sacrificing the essential qualities of the blockchain. It’s unsurprising that numerous projects have emerged that, despite the Scalability Trilemma, opted to scale by compromising on other attributes.

This strategy mirrors the approach taken by Binance Smart Chain. Unlike Ethereum and Bitcoin, Binance Smart Chain does not offer block subsidy rewards. Validators are compensated solely through transaction fees in BNB, with no fixed rewards per block. While the PoSA consensus model allows for quick block times and reduced fees, it sacrifices decentralization and network security.

Users cannot validate the blockchain as easily as they can on Bitcoin or Ethereum. Even if permissionless validation were possible, it would be challenging to do so on standard consumer hardware due to the rapid growth of the state on Binance Smart Chain compared to Ethereum.

CeDeFi enables users to engage with DeFi without incurring exorbitant transaction fees. The affordability encourages experimentation with various DeFi protocols, including decentralized exchanges, lending platforms, liquidity aggregators, and yield farming tools.

Furthermore, CeDeFi familiarizes users with essential DeFi tools like Metamask while providing new teams the opportunity to deploy their smart contracts at a fraction of the cost compared to the Ethereum blockchain. This facilitates testing and gathering feedback on projects, which is often more effective within an ecosystem offering real economic incentives rather than a simple testnet.

Binance Smart Chain has rapidly garnered significant traction, attracting a considerable user base and trading volume in a short time. The decision to fork Ethereum while allowing users and developers to engage with familiar DeFi tools proved to be a shrewd move, coinciding perfectly with market demand.

As millions of new users enter the cryptocurrency arena, it is crucial for them to understand the distinctions between DeFi and CeDeFi, enabling informed decision-making.

Ultimately, we must contemplate: What is the primary benefit of a blockchain that isn't fully decentralized and permissionless? Is it merely audibility? Is this truly the core value proposition of the entire cryptocurrency landscape? Maintain your critical thinking!
