Answer all questions below and test your knowledge.

1
In early 2026, the core trade-off between a validium and a volition using the same ZK proof system for an L2 is primarily defined by what?
Question 1
2
As of early 2026, a primary stated advantage of a sovereign rollup over a smart contract rollup (e.g., an Optimistic or ZK Rollup) is its ability to:
Question 2
3
The 'shared sequencer' model proposed for modular blockchain stacks in 2025-2026 aims to primarily address which limitation?
Question 3
4
In late 2025, a significant shift in ZK-Rollup design involved moving from monolithic proof systems to modular proof aggregation. What is the primary technical benefit of this layered proof architecture?
Question 4
5
As of 2026, the concept of 'enshrined rollups' as part of an L1 protocol design is primarily debated for its potential impact on:
Question 5
6
What is the defining cryptographic feature that distinguishes a 'STARK-based' validity proof from a 'SNARK-based' one, a distinction still fundamental in 2026 implementations?
Question 6
7
In the context of modular blockchains, the term 'interoperability stack' (IBC, LayerZero, etc.) as of 2026 solves a fundamentally different problem than a 'shared sequencer network'. What is that core difference?
Question 7
8
The 'state expiry' model, revisited in Ethereum roadmaps around 2026, proposes to address long-term state growth by:
Question 8
