Computing on Bitcoin #33
April 04, 2025 - Week 14

A fresh edition of Computing on Bitcoin News is now available! 📬
This week, we cover the most exciting shifts in ZK rollups, L2 infrastructure, and bridging protocols.
Let's dive in with this week's curated articles

01
Cardano: enabling Bitcoin DeFi via BitVMX & Lightning Hydra

Cardano is integrating with Bitcoin through Lightning Hydra and BitVMX, enabling secure and scalable Bitcoin DeFi. Additionally, Midnight will enhance privacy, facilitating seamless interaction between Bitcoin, Ethereum, and Solana.

02
BitLayer unveils BitVM bridge

BitLayer showcases its BitVM bridge, demonstrating how it enables trust-minimized BTC transfers to Layer 2. The bridge leverages BitVM for efficient verification, reducing reliance on centralized custodians.

🔗 Showcasing Bitlayer's BitVM Bridge
The BitVM Bridge represents a pivotal development in the broader BitVM ecosystem. Rooted in the groundbreaking work of Robin Linus, the BitVM project has established itself as a cornerstone of trust-minimized cross-chain solutions. Bitlayer’s implementation of the BitVM Bridge directly inherits essential low-level components from this project, which has been collaboratively developed by the BitVM Alliance and the wider BitVM community.

On BitVM's evolution and relevance: Kevin He

Kevin He, co-founder of BitLayer, discusses the design of a Bitcoin L2 with on-chain ZK verification. He explores the use of fraud and validity proofs, BitVM contributions, and Bitcoin-friendly STARKs, balancing scalability, security, and programmability.

@Built on Bitcoin
Kevin He, a seasoned blockchain architect with experience launching multiple L1s/L2s (including Huobi Eco Chain), joins the show to discuss Bitlayer. We explore his journey into crypto, the genesis of Bitlayer, and take a deep dive into BitVM technology - what it is, how it works, its current development status (BitVM 2, Alliance progress, auditing), and how Bitlayer is leveraging it to build trust-minimized Bitcoin L2 solutions, focusing on DeFi. Kevin shares insights on the Bitcoin opcode debate, the future of Bitcoin scaling, and reveals Bitlayer's upcoming BitVM bridge mainnet launch.

Citrea: Bitcoin's fee mechanism proposal

Citrea is designing a fee mechanism to enhance Bitcoin’s scalability while maintaining its security. The model ensures that layer-2 transactions contribute to Bitcoin’s economic sustainability by aligning incentives between users and validators.

🔗 Citrea’s Fee Mechanism: Bitcoin Security at Scale
Citrea’s Fee Mechanism: Bitcoin Security at Scale Citrea’s core value proposition is to enable greater expressivity and increase the utility of Bitcoin blockspace without ever leaving Bitcoin. To achieve this, Citrea keeps data availability and verifiability on-chain, on Bitcoin. Consequently, Citrea inscribes its state changes to Bitcoin and generates a zero-knowledge proof that asserts the validity of those changes. However, inscribing every state change, i.e. transaction, to Bitcoin is not feasible due to high transaction costs and Bitcoin's limited blockspace. Instead, Citrea inscribes the state differences, storage slot differences between the initial and latest state of the given batch, to Bitcoin.

That’s all for now! We hope this edition gave you valuable insights into the evolving world of Computing on Bitcoin.
We’ll catch you next Friday with more to unpack. Don’t miss it!
