Decentralized platform architecture: map the real dependencies
A practical framework for separating interface delivery, execution, data, and administrative control—and testing the dependencies that remain.
Map what you control, what you trust, and what you can replace. Start with the application’s dependencies—not its technology labels.
Decentralization is a question about how authority and dependencies are distributed. Review the interface, identity, execution, data availability, and administration separately. A system may distribute one layer while concentrating another, so a single yes-or-no label hides useful information.
Ethereum’s technical introduction distinguishes a dapp’s smart contract from its frontend. Use that distinction as a starting point, then include the domain, hosting account, RPC endpoint, indexer, and release process in your own map. The useful unit of analysis is a complete action a person needs to perform.
Choose one action, such as reading a membership status or submitting an authorized change. Draw the request from the browser to the component that makes the final decision. Mark where information is cached, interpreted, signed, or stored. An apparently simple page can rely on several independently administered systems.
For each dependency, ask who can alter its behavior and what happens when it is unavailable. A second interface mirror might preserve read-only information without restoring an unavailable API. Describe that limited recovery honestly rather than claiming the whole application has failed over.
A small publication and an application managing shared permissions need different guarantees. Start with the failure that would be unacceptable, then decide which administrative or delivery boundaries need an alternative. More components also mean more maintenance, testing, and coordination.
Write a decision record with the accepted dependencies, rejected alternatives, and evidence still required. Keep the conventional architecture in the comparison. A simpler system with a tested exit path may serve a requirement better than a complicated system whose independence has never been exercised.

No. Specify the required coordination or payment function first. A public static publication can use distributed content delivery without issuing a new token.
Do not assume it is. Record the remaining trust assumptions around software, administrators, data sources, and operators, even when one layer uses shared execution.
