Bitcoin’s Taproot upgrade, activated in November 2021, was more than just a technical enhancement—it was a quiet revolution. While many initially viewed it as a modest improvement focused on privacy and efficiency, its true potential is now becoming evident through innovative applications like Babylon, a Bitcoin-based staking protocol that has already secured nearly 24,000 BTC, worth over $1.6 billion. This case study not only highlights the power of Taproot but also redefines what’s possible within Bitcoin’s conservative architecture.
The Rise of Babylon: A New Era for Bitcoin Staking
Babylon positions itself as the EigenLayer of Bitcoin—a platform enabling users to “re-stake” their BTC to secure other blockchains and earn yield in return. Unlike traditional layer-2 solutions that process transactions off-chain, Babylon operates by leveraging Bitcoin’s native security through time-locked UTXOs (unspent transaction outputs). Users lock their BTC in a custom transaction, effectively pledging it as collateral to support external networks.

This mechanism doesn’t require changes to Bitcoin’s base layer. Instead, it exploits the flexibility introduced by Taproot and Tapscript, allowing complex spending conditions without bloating the blockchain or compromising privacy.
Why Taproot Matters
Before Taproot, creating multi-path smart contracts on Bitcoin was cumbersome and expensive. Every possible redemption path had to be encoded in the script, making transactions large and costly. Taproot changed that with Merkelized Abstract Syntax Trees (MAST)—a concept first proposed by Johnson Lau in 2013—which allows only the executed branch of a script to be revealed during spending.
For Babylon, this means users can define multiple redemption paths—such as regular withdrawal, slashing conditions, or emergency recovery—without exposing unused logic. All paths are cryptographically hidden until needed, preserving both efficiency and privacy.
How Babylon Leverages Taproot and Tapscript
To participate in Babylon staking, users create a specially crafted Bitcoin transaction that sends funds to themselves under a Taproot output. This output contains:
- A public key (for standard spending)
- A Tapscript tree with multiple spending conditions
- An OP_RETURN output embedding metadata like validator identity and reward address
The real innovation lies in the redemption process. When a user wants to withdraw their staked BTC, they can do so via several predefined routes:
- Normal Withdrawal: After the lock-up period ends, the user signs with their private key.
- Slashing Path: If malicious behavior is detected, a proof is submitted to unlock funds via a different script path.
- Recovery Mechanism: In case of key loss or compromise, a time-delayed recovery option kicks in.
All these paths exist within the same Taproot output but remain invisible unless used—thanks to cryptographic commitments in the MAST structure. This level of flexibility was impossible before Taproot.
Comparing Babylon and CoreDAO: Different Approaches, Same Foundation
Both Babylon and CoreDAO utilize Bitcoin’s time-locking feature to enable staking, but their technical implementations diverge significantly.
- CoreDAO relies on simpler scripting methods, often using pay-to-script-hash (P2SH) structures that expose full script details upon redemption.
- Babylon, by contrast, fully embraces Tapscript’s conditional logic, enabling more sophisticated and private staking mechanisms.
Moreover, while Ordinals introduced NFT-like assets on Bitcoin using brute-force inscription methods, Babylon demonstrates a more elegant use of Taproot—one aligned with Satoshi’s vision of scalable, secure value transfer rather than data bloat.
This distinction underscores an important truth: Taproot wasn’t built for gimmicks—it was built for functionality.
Addressing Criticism: Is Bitcoin Innovation Stagnant?
Critics have long argued that Bitcoin’s development is too slow, risk-averse, or disconnected from modern crypto trends. Some claim its engineers resist meaningful upgrades, favoring stability over progress.
Babylon’s success directly challenges this narrative. By harnessing Taproot’s advanced scripting capabilities, it proves that Bitcoin can support cutting-edge decentralized applications—without sacrificing decentralization or security.
In fact, adoption of Taproot has surpassed expectations:
- Over 90,000 BTC are now held in Taproot addresses
- More than 7% of all Bitcoin transactions use Taproot outputs
- Developer activity around Tapscript-based projects is growing steadily
These numbers reflect not stagnation, but strategic evolution—a deliberate pace that prioritizes robustness over hype.

The Bigger Picture: What Babylon Means for Bitcoin’s Future
Babylon isn’t just another yield-generating protocol. It represents a paradigm shift: Bitcoin as a foundational security layer for the broader blockchain ecosystem.
By allowing BTC holders to lend their hash power and economic security to other chains, Babylon turns passive assets into active participants in cross-chain validation. This concept—known as “restaking”—mirrors EigenLayer’s model on Ethereum but adapts it natively for Bitcoin’s UTXO model and scripting constraints.
And crucially, it does so without forking the network or introducing new tokens on Bitcoin itself. Everything runs atop existing consensus rules, enhanced by Taproot’s expressive power.
Frequently Asked Questions (FAQ)
What is the Taproot upgrade?
Taproot is a Bitcoin soft fork that improves privacy, efficiency, and smart contract functionality by combining Schnorr signatures, MAST, and Tapscript. It enables complex transaction logic while making most transactions look like standard payments.
How does Babylon use Taproot?
Babylon uses Taproot to create multi-path staking contracts where only the executed spending condition is revealed. This allows secure, private, and efficient staking mechanisms without bloating the blockchain.
Is Babylon a layer-2 network?
No. Babylon is not a layer-2 scaling solution. It doesn’t process transactions off-chain. Instead, it’s a protocol that leverages Bitcoin’s security through time-locked UTXOs and cryptographic commitments enabled by Taproot.
Can anyone build apps like Babylon on Bitcoin?
Yes—but with limitations. Developers need deep expertise in Bitcoin scripting and must work within the constraints of its consensus rules. However, Taproot has significantly expanded what’s possible, opening doors for more advanced DeFi-like applications.
Does Babylon mint new tokens on Bitcoin?
No. Babylon does not issue tokens directly on the Bitcoin blockchain. Rewards and points are tracked off-chain or on external chains. The protocol focuses on securing external networks using BTC as collateral.
Is Taproot widely adopted?
Yes. Adoption has grown steadily since 2021. Major wallets like BitBox, Specter, and BlueWallet support Taproot, and high-value transactions increasingly use P2TR (Pay-to-Taproot) addresses for better privacy and lower fees.
Conclusion: Taproot Is Changing the Game
The success of Babylon—securing over $1.6 billion in staked BTC—is not just a win for one project. It’s a validation of Bitcoin’s ongoing innovation and the transformative power of the Taproot upgrade.
Far from being obsolete or stagnant, Bitcoin continues to evolve through carefully engineered upgrades that unlock new functionalities without compromising its core principles. Babylon exemplifies how these enhancements can be used to build secure, scalable, and privacy-preserving systems that extend Bitcoin’s utility far beyond simple payments.
Whether or not you believe in staking or restaking models, one thing is clear: Taproot works, and it's already shaping the future of Bitcoin-based innovation.
