BounceBit's Philosophy

The domain of Bitcoin Layer 2 solutions is undergoing a transformative phase, characterized by the emergence of diverse methodologies and innovative frameworks. BounceBit introduces a paradigm shift, drifting away from Layer 2 and drifting towards the concept of Layer 1 sidechain. We invite you to delve into the philosophy and strategic decisions that form the development of BounceBit—a chain that reenvisions the role of BTC.

Reimagining Bitcoin’s Value: BounceBit’s Asset-Driven PoS Layer 1 Approach

At the core of BounceBit’s innovative framework lies the conviction that Bitcoin’s infrastructure should be predominantly asset-driven, a philosophy that accentuates the versatility of BTC. Rather than tethering itself to the constraining paradigms of existing Layer 2 solutions anchored directly to the Bitcoin blockchain, BounceBit distinguishes itself as a standalone Proof of Stake (PoS) Layer 1 ecosystem. In this distinct network, validators are required to stake both native BounceBit tokens and BTC, establishing a dual-token security system that not only strengthens the network but also enhances the intrinsic value of BTC by enabling its active role in network validation.
This unique approach avoids traditional protocol-level bindings in favor of an asset-level integration, effectively merging the reliability of Bitcoin with the innovative potential of BounceBit’s native functionalities. By doing so, BounceBit creates a symbiotic relationship between BTC and its own token, leveraging the strengths of each to create a more resilient and versatile chain.
Going beyond the confines of the Bitcoin main chain, BounceBit embraces interoperability with EVM-compatible chains, recognizing and incorporating staked assets such as BTCB on the BNB chain and WBTC. This diversifies the use cases for staked BTC but also invites Web 3-wide participation, thereby enriching the entire BTC asset class.

Transparent CeFi as the Bedrock for the BTC Ecosystem

In the context of Bitcoin, the generation of interest on BTC presents a unique challenge, one that differs substantially from the yield-generating mechanisms associated with Ethereum’s Lido. The prevalent Bitcoin protocols, akin to Blast and Manta on Ethereum, fail to yield returns when BTC is held within multi-signature wallets. BounceBit confronts this issue head-on by integrating a transparent centralized finance (CeFi) model, utilizing Mainnet Digital’s custody services complemented by Ceffu's MirrorX technology. This allows Bitcoin to maintain its on-chain presence while at the same time engaging in trading activities on centralized exchanges (CEX). The outcomes of these trades are reconciled on-chain with a T+1 settlement cycle, ensuring liquidity and transparency.
BounceBit’s vision is to reinforce rather than replace the integrity and trust inherent in CeFi. By enhancing its transparency, we establish a new foundational moment for Bitcoin, mirroring Ethereum’s pivotal shift with Lido. Our approach aims to solidify trust in CeFi practices, by giving the right reasons to do so.

Mobilizing Active Bitcoin in the Ecosystem

Recognizing the inherent conservatism of Bitcoin holders, especially regarding the movement of assets from secure cold storage, BounceBit implements an initiative aimed at activating the most liquid and actively used BTC. This segment of Bitcoin is typically engaged on EVM-compatible networks and centralized exchanges, where it is at the core of trading, lending, and borrowing pursuits in search of yield.
BounceBit supports the seamless transition of pure BTC into more agile forms such as BTCB on the BNB chain and Wrapped Bitcoin (WBTC), facilitating their entry into productive activities. Users are provided with the option to deposit their BTC into a secure custody service accessible through the EVM network, thus enabling the bridging of these assets onto the BounceBit platform. This process allows for the accrual of on-chain yields without needing direct interactions with the Bitcoin main chain.
