Latest News:

According to official news, Babylon has launched the Bitcoin staking mainnet, and users can participate in the first phase of the Babylon Bitcoin staking mainnet.

The launch of the Babylon Bitcoin staking mainnet brings a third native use case to Bitcoin assets beyond value storage and simple payments: staking to secure PoS networks and earn rewards.

What is Babylon?

Babylon is a layer 1 blockchain founded by Professor David Tse of Stanford University. The mission of the project is to bring Bitcoin's unparalleled security to all PoS blockchains without any additional energy costs. The team consists of researchers from Stanford University, experienced developers, and seasoned business advisors.

What problem does Babylon solve?

BTC currently has a market value of over $1.97 trillion, but due to issues such as Bitcoin not supporting smart contracts and scalability challenges, its value has long remained locked. Babylon proposes a new way to expand Bitcoin by extracting security from the Bitcoin chain and sharing it with various Proof of Stake (PoS) chains, such as Cosmos, Binance Smart Chain, Polkadot, Polygon, etc., thus providing yields for BTC staking providers while ensuring the security of PoS chains.

Babylon's vision is to extend Bitcoin's security to protect a decentralized world. By leveraging three aspects of Bitcoin—its timestamp service, block space, and asset value—Babylon can transfer Bitcoin's security to numerous Proof of Stake (PoS) chains, thereby creating a more robust and unified ecosystem.

Babylon's Bitcoin staking protocol adopts a remote staking method, overcoming the lack of smart contracts through cryptography, consensus protocol innovations, and optimizing the use of Bitcoin script language. Babylon's staking protocol allows Bitcoin holders to reliably stake Bitcoin without the need to bridge to PoS chains, providing full slashing security guarantees for those chains. This innovative protocol eliminates the need for bridging, wrapping, or custody of staked Bitcoin.

A key aspect of Babylon is its BTC timestamp protocol. It timestamps events from other blockchains onto Bitcoin, allowing these events to enjoy Bitcoin's timestamping like Bitcoin transactions. This effectively borrows the security of Bitcoin as a timestamp server. The BTC timestamp protocol achieves rapid unstaking, composable trust, and reduced security costs to maximize the liquidity of Bitcoin holders. The protocol is designed as a modular plugin that can be used on various PoS consensus algorithms and provides a basis for constructing reset protocols.

Important team members of Babylon:

Mingchao (Fisher) Yu is the founder and CTO of Babylon. From 2015 to 2017, he was a lecturer at the Australian National University and a senior systems engineer at InterfereX Communications. He was a postdoctoral researcher at the University of Southern California from 2017 to 2018. From 2018 to 2022, he served as a senior research engineer and principal engineer at Dolby Laboratories.

David Tse is the co-founder of BabylonChain. David Tse graduated from MIT and later became a professor at Stanford University and the University of Chicago's engineering school. He is a member of the National Academy of Engineering. His research interests include information theory, computational genomics, machine learning, and blockchain.

Babylon Funding Details:

The investment lineup is very impressive, according to Rootdata news:

  • Seed round of $8 million in January 2022

  • 2023 / December Series A $18 million

  • 2024 / May Completion $70 million

  • In addition to the above, Binance Lab also participated in investing in Babylon, but the investment amount has not been disclosed.


Babylon's financing background is considered relatively luxurious within the entire Bitcoin ecosystem and is led by well-known VC Paradigm.

Babylon Vision:

Bitcoin is the first blockchain and remains the top blockchain by total market capitalization. However, its utility is limited beyond value storage due to the small block space, high latency, and lack of programmability. In particular, blockchain practitioners have struggled to extend the Bitcoin chain and broaden its use cases by building side chains and other second-layer projects, but they have faced difficulties in bridging large amounts of Bitcoin to these chains. These bridges are either constrained by security issues, capacity limitations, or both.

Babylon brings an unprecedented important use case for Bitcoin assets: by staking Bitcoin, it provides security for the PoS world. Babylon proves that, at least in this use case, there is no need to bridge Bitcoin assets to other blockchains to provide comprehensive economic security for PoS chains.
