TOPIC GUIDE 16 / Architecture & Web3

Ethereum Decentralized Platform

Review Ethereum as an execution layer inside a complete application. Keep contracts, interfaces, data access, and upgrade powers in the same design.

Architecture & tradeoffsPractical next stepsOpen to read

Define the rule to be enforced

Start with a narrow application invariant, such as who may issue a membership and how revocation changes access. Describe it independently of a frontend. Ethereum’s dapp documentation separates contract execution from the interface that presents it to a user.

Identify the state the application treats as authoritative and the information assembled for convenience by an indexer. An attractive dashboard does not tell a reviewer which layer actually enforces permissions.

Prototype the full transaction journey

Build account selection, request preparation, user authorization, submission, and the application’s chosen confirmation behavior. Include a rejected request, a delayed response, and a stale page. Make uncertainty visible rather than treating any returned identifier as a complete success condition.

Keep test and production environments distinct. Record the intended deployment identifiers with the interface release and verify them during review. Never request a reader’s private key or seed phrase to diagnose an application problem.

Include operating dependencies in the comparison

Record RPC access, derived indexes, hosting, naming, and administrative authority. Test an alternative endpoint and a reconstructed interface in staging. Describe what remains functional when an optional service is unavailable.

Compare the same user journey on another execution environment when that is a genuine design question. Use implementation clarity, rule enforcement, recovery behavior, and total operating effort as criteria. Avoid a universal chain ranking based on isolated fee or speed claims.

Questions worth asking

Is a contract enough to make the entire site decentralized?

No. Its frontend, naming, RPC access, external data, and administrative controls remain separate parts of the application architecture.

How should Ethereum be compared with Solana?

Prototype the same small application and compare state modeling, permissions, wallet behavior, data access, recovery, and operating effort under documented conditions.
