Up to now, it is quite clear that the inherent limitations of Bitcoin have been the motivation to inspire change and make the greatest leaps forward, with devs reimagining its architecture and expanding the notion of what Bitcoin as a network means, not just what its value is.
An article by Messari provides an in-depth overview of Hemi, a modular Bitcoin Layer-2 embedding a full Bitcoin node within an EVM. It explains Hemi’s Proof-of-Proof consensus, tunneling mechanism, and DeFi ecosystem, and its roadmap toward ZK-based settlement for Ethereum and BitVM2-powered verification for Bitcoin.

Understanding Hemi: A Comprehensive Overview
Efforts to extend Bitcoin’s capabilities through wrapped assets or merged-mined sidechains have introduced tradeoffs in custody, decentralization, and developer flexibility.
Hemi is a modular Layer-2 (L2) protocol designed to address these limitations. Its architecture embeds a full Bitcoin node within an Ethereum Virtual Machine (EVM), enabling Solidity contracts to observe and respond directly to Bitcoin’s UTXO state.
A new BitDevs Buenos Aires meetup has been announced for Thursday, October 30, featuring a talk by Sergio Demian Lerner on BitVMX. Attendance is free with prior registration.

With our advanced zkVM and BitVM2-based architecture, decentralized sequencers, and trustless yield model, we aim to become the go-to infrastructure partner for institutions seeking Bitcoin-based yield solutions.
If market volatility drives Bitcoin prices lower, the ability to stake or lock BTC for sustainable returns will be even more compelling — offering a rational, long-term alternative to selling.
A new article by On-Chain Bitcoin critically examines the trustlessness of Babylon’s BTC vaults, analyzing their BitVM3 and garbled circuit design and highlighting key off-chain trust assumptions behind the system.

Concurrently, technical advancements included a demo by Input Output Hong Kong (IOHK) and FairGate Labs, showcasing Cardano smart contracts operating on Bitcoin via BitVMX and a UPLC-to-RISC-V compiler. This development enabled Bitcoin users to access Cardano-based tools, fueling broader discussions on blockchain interoperability.
That’s it for this week’s Computing on Bitcoin News.
From research deep dives to new community events, Bitcoin’s builder ecosystem keeps accelerating — and we’ll be here to track every step forward.
