$In the cryptocurrency field, Bitcoin (BTC), as the undisputed pioneer and king, has become a benchmark for the value storage of digital assets since its inception due to its decentralization and fixed total supply characteristics, profoundly influencing the global financial landscape. However, Bitcoin has limitations in smart contract functionalities and participation in complex financial activities, creating a clear gap with the rapidly developing decentralized finance (DeFi) world. The emergence of BounceBit is like a ray of light, opening a door to diversified earnings for Bitcoin holders through its innovative CeDeFi framework and BTC restaking chain, while also reshaping the entire landscape of crypto finance.

The dilemma of Bitcoin and the booming development of DeFi

Bitcoin was born in 2009, and Satoshi Nakamoto's creation first gave people a digital currency based on a decentralized ledger that does not require trusting third parties. Over the past decade, Bitcoin’s price has repeatedly set new highs, and its market capitalization accounts for a significant portion of the entire cryptocurrency market, becoming a crucial component in many investors' asset allocations, widely regarded as 'digital gold', serving as a store of value and a safe-haven asset.

However, the original intention of Bitcoin's design was not to achieve complex financial functions. Its smart contract capability is extremely limited; while the script language based on Bitcoin can implement simple transaction logic, it is far from comparable to smart contract platforms like Ethereum and is difficult to support a rich array of DeFi applications like lending, trading, and liquidity mining. The Bitcoin network also faces bottlenecks in transaction processing speed; during network congestion, transaction confirmation times are long, and transaction fees are high, significantly limiting the application of Bitcoin in everyday financial transaction scenarios.

In contrast, DeFi has rapidly risen based on smart contract platforms like Ethereum. The DeFi ecosystem provides a wide variety of financial services, from decentralized lending protocols like Aave and Compound to trading platforms such as Uniswap and SushiSwap that employ automated market maker (AMM) models, and various liquidity mining, yield farming, and other innovative features, allowing users to freely conduct asset borrowing, trading, and investment operations without traditional financial intermediaries, achieving asset appreciation. The rapid development of DeFi has attracted a large influx of funds and developers, showcasing strong innovative vitality. However, DeFi is not without flaws; issues such as smart contract vulnerabilities, impermanent loss, market manipulation, and lack of effective regulation constantly threaten the security of users' assets and the stable development of the DeFi ecosystem.

BounceBit's CeDeFi innovative architecture

1. Fusion of centralization and decentralization

BounceBit has innovatively proposed the CeDeFi (Centralized Empowered Decentralized Finance) framework, aimed at integrating the advantages of CeFi and DeFi while overcoming the shortcomings of both. In the BounceBit system, the custody of user assets adopts a centralized model, collaborating with compliant and experienced custody institutions Mainnet Digital and Ceffu. These two custody institutions have a good reputation and strict security measures in the field of crypto asset custody. After users deposit Bitcoin into the BounceBit protocol, their assets are securely held in regulated custody accounts, greatly reducing the risk of theft and loss, addressing the long-standing issue in DeFi of asset loss due to smart contract attacks, while also meeting regulatory compliance requirements, allowing institutional investors and ordinary users to participate with greater peace of mind.

2. Unique design of the dual-token PoS mechanism

BounceBit adopts a unique dual-token Proof of Stake (PoS) mechanism, which is one of its core innovations. The platform has two key tokens: the native token BB and the Bitcoin-backed BBTC. In the BounceBit network, validators need to stake both BBTC and BB to participate in block production and maintain network security. This dual-token design brings multiple advantages. On one hand, it fully utilizes Bitcoin's security, incorporating Bitcoin into the staking system, allowing the BounceBit network to inherit Bitcoin's strong security foundation; on the other hand, the introduction of the native token BB incentivizes more participants to actively participate in network validation and governance, enhancing the decentralization and stability of the network. The platform also has a comprehensive penalty mechanism (Slashing) and reputation system. If a validator engages in malicious behavior, such as double spending attacks or intentionally delaying block production, some of their staked tokens will be partially forfeited, and their reputation will be damaged, affecting their future earnings and participation eligibility in the network; while honest validators can earn substantial rewards, including newly generated tokens and transaction fee sharing, ensuring the normal operation and security of the network.

3. EVM compatibility expands application boundaries

BounceBit has achieved full compatibility with the Ethereum Virtual Machine (EVM). This feature is significant as it allows thousands of smart contracts and decentralized applications (DApps) on Ethereum to easily migrate to the BounceBit platform. Developers do not need to relearn a new programming language and development framework, as they can utilize the existing tech stack to develop on BounceBit, greatly reducing development costs and barriers. This not only enriches the variety of applications in the BounceBit ecosystem but also attracts developers and users from the Ethereum ecosystem, promoting the rapid prosperity of the BounceBit ecosystem. For example, popular DeFi lending protocols and NFT markets based on Ethereum can run on BounceBit after simple adaptations, allowing Bitcoin holders to enjoy the convenience and benefits brought by these innovative applications.

Analysis of BounceBit's revenue model

1. CeFi yields: Robust low-risk arbitrage

In terms of CeFi yields, BounceBit has established partnerships with several centralized exchanges, utilizing professional quantitative trading teams and algorithms to obtain profits for users through low-risk strategies such as funding rate arbitrage. Funding rate arbitrage takes advantage of the differences in Bitcoin funding rates between different exchanges. For example, at certain times, the Bitcoin lending rate on Exchange A is 3% annually, while on Exchange B, it is 5% annually. BounceBit can borrow Bitcoin at a lower rate on Exchange A and lend it out at a higher rate on Exchange B, earning the interest differential. This arbitrage strategy is relatively low risk and provides stable returns. Furthermore, by cooperating with compliant custody institutions, it ensures the safety of user assets during trading. Users do not need to monitor complex market conditions and trading operations; they can simply deposit Bitcoin into the BounceBit platform and enjoy this portion of CeFi yields.

2. DeFi yields: Diverse on-chain financial activities

In the DeFi yield section, BounceBit offers users a rich variety of choices. Users can utilize the mapped BBTC tokens to participate in various DeFi applications. In the lending market, users can use BBTC as collateral to borrow other digital currencies or lend out their BBTC to earn interest. Taking the Aave protocol as an example, users deposit BBTC into Aave's lending pool, and Aave will provide corresponding interest returns based on market supply and demand and risk assessment, with the current annual interest rate fluctuating around 4% - 8%. In the liquidity mining field, users can pair BBTC with other digital currencies to provide liquidity to automated market maker (AMM) platforms, such as the application of Uniswap's fork on BounceBit. By providing liquidity, users help maintain market trading depth and liquidity, thereby earning transaction fee sharing and liquidity mining reward tokens issued by the platform. The value of these reward tokens may increase with the platform's development, bringing additional earnings to users.

3. Staking and restaking yields: Enhancing capital efficiency

Staking and restaking are major highlights of BounceBit's revenue model. By staking BBTC and BB, users participate in node validation in the BounceBit network and can earn node operation rewards, including newly generated BB tokens and transaction fee sharing. The LSD (Liquid Staking Derivative) tokens generated from staking have unique value, allowing users to use them for restaking in other protocols without解除 the original staking status, achieving a layering of earnings. For example, users can stake LSD tokens into the Restake Finance protocol, which will utilize LSD tokens for restaking across different validation nodes and networks, bringing additional earnings to users. This restaking mechanism greatly improves capital efficiency, allowing users' assets to work across multiple scenarios, maximizing earnings. Depending on market conditions and the yield levels of different protocols, the comprehensive annualized yield from staking and restaking can reach 10% - 20% or even higher.
