[image] 1/5 I expected the first public testnet experience to teach me about the blockchain. Instead, it taught me how people begin to understand one. Watching @RetiumChain's wallet launch changed the question for me.

[image] 1/5 I used to think blockchain scalability was mostly about processing more transactions. But studying @RetiumChain changed the question for me. The deeper challenge is not only execution. It is how a protocol distributes different responsibilities across its architecture.

[image] 1/5 I used to think transaction fees were simply the cost of using a blockchain. But @RetiumChain's Logic Weight made me separate two things: competitive bidding → market-driven price Logic Weight → computational-cost-based price Same fee. Different resource model.

[image] 1/5 Why does @RetiumChain place a separate stage between Validation and Execution? Its transaction pipeline calls that stage: Staging. That raises a more interesting question: what happens between “valid” and “execute”?

[image] 1/5 I used to think determinism was one property of a blockchain. In @RetiumChain, it appears in two different places: Prime factors make block structure reproducible. WASM makes contract execution reproducible. So why does one network need both?

[image] 1/5 I used to think deterministic execution solved the agreement problem. In @RetiumChain: same contract + same input + same state → same result across nodes. Yet validators still need consensus. Because reproducibility and network agreement solve different problems.

[image] 1/5 Why does @RetiumChain separate transaction finality from block finality? I used to assume they described the same process. But Retium treats them as two different paths. So what does each one actually describe?
