Ark 101 - Scaling Bitcoin with Transaction Batching
Veronika Kütt

Ark is a Bitcoin-native transaction batching technique that enables scalable, near-instant payments without sacrificing self-custody or Bitcoin finality. It uses a shared UTXO model coordinated by an always-on operator, where most payments are executed offchain and periodically anchored to Bitcoin via onchain settlement.

This workshop introduces the core concepts behind Ark, including Virtual UTXOs (VTXOs), commitment transactions, transaction trees, and unilateral exits. Participants gain an intuitive understanding of Ark’s trust model, how atomicity between batches is enforced without covenants, and where Ark fits into the broader Bitcoin scaling landscape alongside the Lightning Network.

Scaling Bitcoin - Second Layer Solutions and Tradeoffs
Ricki Allardice, Veronika Kütt, joschisan, Gareth Grobler

Bitcoin’s base layer prioritizes security and decentralization, but this comes with strict limits on throughput and latency. As Bitcoin adoption grows, second-layer solutions are becoming essential to scale usage without compromising core properties.

This panel explores the current landscape of Bitcoin scaling approaches, including the Lightning Network, transaction batching techniques, and emerging Layer 2 designs. Panelists will discuss architectural tradeoffs around custody, trust assumptions, liquidity, finality, and user experience, highlighting where different solutions excel, where they fall short, and what open questions remain for scaling Bitcoin sustainably.
