Key Points Summary
Babylon is an innovative project that aims to enhance the economic security of Proof of Stake (PoS) blockchains and the security of decentralized applications (dApps) by allowing Bitcoin holders to stake their Bitcoin (BTC) and earn rewards.
Babylon leverages three unique features of Bitcoin, including its timestamp service, block space, and asset value.
Through Babylon, Bitcoin holders can lock their BTC on the Bitcoin network to participate in the security of PoS. These staked BTC are then used to secure various PoS ecosystems, such as Cosmos, Polygon, and Bitcoin's second-layer network.
1. What is Babylon?
Babylon is an innovative project that aims to enhance the economic security of Proof of Stake (PoS) blockchains and the security of decentralized applications (dApps) by allowing Bitcoin holders to utilize idle Bitcoin and earn rewards.
Babylon allows users to provide security for other blockchains and protocols by staking Bitcoin (BTC), expanding the role of Bitcoin in decentralized finance. This process does not require cross-chain, wrapping, pegging, or custody of staked Bitcoin. The project achieves this goal by leveraging three unique features of Bitcoin—its timestamp service, block space, and asset value. Babylon aims to extract security from the pioneering blockchain platform of Bitcoin and distribute it to various Proof of Stake (PoS) ecosystems, such as Cosmos, Polygon, and Bitcoin's second-layer network.
1) Team and Financing
The Babylon team consists of key figures and renowned scholars, including co-founders David Tse and Fisher Yu. Babylon also has an advisory team providing professional guidance and strategic insights. The project's ecosystem continues to grow through collaborations with multiple partners, including Lombard, Akash Network, Binance Web3 Wallet, Injective (INJ), Cosmos Hub, and OKX Wallet.
Babylon has received strong support and financing, reflecting market confidence in its innovative approach. For example, in December 2023, the project raised over $18 million from top investors, including Polychain Capital, Hack VC, OKX Ventures, Polygon Ventures, and others. This substantial investment will be used to develop Babylon's Bitcoin staking protocol, positioning Bitcoin as a decentralized staking asset.
With a strong team and ample funding, Babylon has gained a favorable position in the market by combining Bitcoin's security with decentralized finance (DeFi). Its unique staking protocol aims to expand the utility of Bitcoin and enhance the security of PoS blockchains, demonstrating the project's commitment to on-chain integrity.
2) How Does Babylon Work?
As mentioned earlier, Babylon is able to provide security for Proof of Stake (PoS) chains by leveraging three unique features of Bitcoin—timestamp service, block space, and asset value. These elements form the core of Babylon's security sharing protocol, including the Bitcoin staking protocol, Bitcoin timestamp protocol, and Bitcoin data availability protocol.
These protocols work together to ensure the effective utilization of Bitcoin's robust features to enhance the security and efficiency of various PoS networks. Here are detailed explanations of these protocols and how they operate.
2. Bitcoin Staking Protocol
Bitcoin holders can use Babylon's Bitcoin staking protocol on PoS chains, application chains, and applications by staking (and restaking) their BTC to secure the protocols and earn rewards. Unlike traditional staking methods, this protocol does not require cross-chain, wrapping, or third-party custody of staked Bitcoin.
The staking protocol serves two intertwined functions. Firstly, it enhances the security of the Proof of Stake chain and applications through Bitcoin staking. Additionally, it incentivizes Bitcoin holders to participate in Babylon's security model through a reward mechanism.

Notably, Babylon's staking protocol claims that the BTC deposited into the protocol is "as secure as possible." For example, as long as participants use the protocol in good faith and do not attack the PoS chain, the staked Bitcoin is secure and can be withdrawn. Additionally, due to Babylon's use of the Bitcoin timestamp protocol, the unbinding of staked assets is typically safe and swift without the need for social consensus.
In summary, the BTC staking protocol is designed as a modular plugin compatible with various Proof of Stake (PoS) chains. By integrating Bitcoin's robust security into these blockchains, Babylon aims to expand the utility of BTC beyond just a store of value or medium of exchange.
1) Bitcoin Timestamp Protocol
The Bitcoin timestamp protocol is another crucial component of Babylon. This protocol effectively utilizes BTC as a secure timestamp server by recording timestamp events of other blockchains on the Bitcoin network. Essentially, it allows any random data submitted to Babylon to obtain a timestamp from Bitcoin.

The Bitcoin timestamp protocol is particularly useful in enhancing the integrity and security of PoS networks and preventing long-range attacks—where malicious validators attempt to take over a blockchain by forking a fake chain. Through the Bitcoin timestamp, an attacking fork will have a later Bitcoin timestamp, making it unlikely to be selected by anyone. It also establishes synchronization between Bitcoin and PoS blockchains, eliminating the need for social consensus as Bitcoin timestamps are objective.
Furthermore, the timestamp protocol facilitates cross-chain security, rapid staking unbinding, reduced security costs, composable trust, and the bootstrapping of new chains. It achieves these goals by combining the short-term security of Proof of Stake chains with the long-term security of Proof of Work Bitcoin.
2) Bitcoin Data Availability Protocol
Bitcoin Data Availability Protocol utilizes Bitcoin's limited block space to perform critical tasks, such as providing an anti-censorship layer for PoS chains. Bitcoin's block space is renowned for its unparalleled security and resistance to censorship, which is crucial for safeguarding decentralized ecosystems. The data availability protocol ensures that critical data is always accessible and secure, further enhancing the reliability and trustworthiness of PoS chains.
3. Problems Addressed by Babylon
Through its various mechanisms, Babylon provides solutions to challenges in the blockchain ecosystem, including:
1) Establishing Protocol Security for New Chains
New blockchain platforms often face security issues in their early stages. These networks are more susceptible to attacks shortly after launch and typically require robust security infrastructure to maintain their integrity.
With Babylon, newly launched blockchains can leverage the security of Bitcoin to enhance their overall stability and reliability. For example, Babylon's timestamp protocol can help protect new blockchain networks from long-range attacks by utilizing Bitcoin's timestamp.
2) Improving Bitcoin's Capital Efficiency
Babylon allows Bitcoin holders to stake their Bitcoin on PoS chains, thereby increasing the capital efficiency of the Bitcoin ecosystem. As mentioned earlier, the staking protocol eliminates the need for cross-chain, wrapping, or third-party custody of Bitcoin, maintaining liquidity. This ultimately expands the use cases of Bitcoin in the ecosystem, from securing PoS networks to earning staking rewards.
3) Fast Unbinding
In many staking protocols, the process of unbinding stakes can be time-consuming, reducing participants' flexibility and reluctance to detach their assets. However, Babylon ensures fast unbinding by synchronizing Bitcoin with PoS chains through the use of Bitcoin timestamps, allowing users to access their funds quickly.
4. Partners and Ecosystem
As mentioned earlier, Babylon has established a strong ecosystem through strategic partnerships with several prominent projects in the blockchain space. These partnerships focus not only on technology but also on collectively working towards a more secure and efficient decentralized future. Here are some key partners and components of Babylon's ecosystem.
1) Lombard
One of Babylon's most important partners is Lombard, a startup company dedicated to integrating Bitcoin into the DeFi ecosystem. With Babylon's involvement, Lombard raised $16 million to explore the untapped area of re-staking Bitcoin.
It is worth noting that the concept of re-staking was initially introduced on Ethereum through EigenLayer. EigenLayer is a protocol that allows participants to re-stake their staked assets to secure other Ethereum applications and earn additional rewards.
The collaboration between Babylon and Lombard will utilize Lombard's introduction of "Liquid Bitcoin" (LBTC) Token. The LBTC Token is a tradable certificate for Babylon deposits, allowing users to maintain liquidity while staking Bitcoin.
Additionally, LBTC can freely transfer between different blockchains, providing users with flexibility and accessibility. This cross-chain capability ensures that Bitcoin holders can leverage DeFi opportunities across multiple platforms.
The collaboration between Lombard and Babylon is part of a broader strategy to connect PoS chains with Bitcoin-backed security, providing limitless DeFi opportunities for Bitcoin holders. This integration not only benefits users but also enhances the liquidity and security of the entire ecosystem.
2) Akash Network
Akash Network is a decentralized cloud infrastructure that empowers users with control over pricing and services while enjoying efficient transactions and minimal environmental impact. The network's collaboration with Babylon enhances its security by integrating Bitcoin's robust features into its Proof of Stake (PoS) system.
These security measures enable Akash to provide users with more secure and cost-effective transaction records and workload deployments. The collaboration with Babylon significantly enhances security and efficiency, further solidifying Akash's position in the market.
Furthermore, this collaboration allows Akash Network to leverage Bitcoin's reliable timestamp service and source of trust. This integration prevents double-spending attacks and supports rapid staking unbinding, providing users with greater flexibility and confidence in asset security.
Ultimately, by leveraging Babylon's technology, Akash can provide better scalability to meet the growing needs of its user base. With advanced security measures, Akash Network aims to provide a secure and cost-effective decentralized cloud solution, continuously pushing the boundaries of decentralized cloud computing.
3) Cosmos Hub
The Cosmos Hub is an independent parallel chain network designed with the Cosmos software development kit (SDK). Through the Bitcoin staking protocol, the collaboration between Cosmos and Babylon allows Bitcoin holders to stake their Bitcoin to secure the Hub's consumer chains and earn additional rewards.
4) Cosmos Hub
Cosmos' blockchain ecosystem enhances the security aggregation of the Cosmos Hub blockchain and all consumer chains by leveraging Babylon's Comet extension. In short, integrating Babylon's technology into the Hub prevents adverse scenarios such as double signatures.
- Bitcoin Layer 2
While Bitcoin is undoubtedly the most secure network in the crypto space, it still has limitations in smart contract functionality and support for other digital assets. This deficiency has led to the development of Bitcoin Layer 2 solutions aimed at expanding Bitcoin's capabilities.
However, these Layer 2 (L2) solutions often rely on third-party custodians or multi-signature bridges to facilitate their operations, contradicting Bitcoin's decentralized principles. Ultimately, this reliance may raise concerns about security and control, as users may find it challenging to trust these intermediaries to properly manage and protect their assets.
Fortunately, Babylon's Bitcoin staking protocol addresses these challenges by allowing users to stake Bitcoin directly. This enhances the security of PoS networks without the need for third-party custody or wrapping. This seamless integration benefits both the Bitcoin ecosystem and PoS networks.
Some Layer 2 projects have already begun utilizing Babylon's Bitcoin staking protocol, including Lorenzo and Bison. For example, Lorenzo is a Bitcoin L2 infrastructure focused on yield-bearing token issuance, trading, and settlement. By leveraging Babylon's staking protocol, Lorenzo enables native Rollups to integrate native BTC assets and stake BTC for yield.
Meanwhile, Bison Network is a Bitcoin-based ZK-STARK Rollup that provides general programmability, allowing developers to design decentralized applications (dApps), smart contracts, and other DeFi tools. Bison essentially offers Bitcoin-native smart contract functionality while using Babylon's infrastructure to enhance transaction efficiency and overall security.
6. Conclusion
Babylon leverages Bitcoin's secure architecture to protect Proof of Stake (PoS) blockchains while allowing Bitcoin holders to securely earn rewards. Its innovative staking protocol not only ensures robust security for PoS chains but also provides users with liquidity and control. The project highlights that Bitcoin is not just a store of value but can also serve as a trusted security pillar for other blockchains. Through strategic partnerships with Lombard and Akash Network, among others, Babylon continues to strengthen its ecosystem and expand its role in the decentralized finance (DeFi) industry.
