🔗 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.

Scaling Bitcoin with BitVM & Bitlayer | Kevin He Interview Co-Founder of Bitlayer

@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’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.
