Got it — blockchain design patterns, focused on systems-level concepts.

You're familiar with general system design (to some extent) and want to strengthen knowledge of particular blockchain design patterns. Before we start, a few quick clarifiers so I can tailor questions and explanations:

Pick the subtopics you want to focus on (select all that apply)

Consensus algorithms (PoW, PoS, BFT variants)
Layer-1 scaling (sharding, state rent, execution engines)
Layer-2 patterns (rollups, payment channels, sidechains)
Data availability & erasure coding
Finality & fork-choice (instant vs probabilistic)
State management & storage patterns (account vs UTXO, pruning)
Security patterns (slashing, fraud proofs, exit games)
Governance & upgrade patterns (on-chain/off-chain upgrades)
Interoperability (bridges, IBC-like relayers)
Decentralization vs performance trade-offs

What depth do you want? Conceptual (high-level patterns, intuition) Architectural (component diagrams, trade-offs) Implementation (protocol messages, pseudo-code)

Optional: Tell me about your background and goal in one short sentence

Anything else that would help me tailor this?

Learning: I am familiar with general system design (not that much) but I am in t
