Solution Architecture Design

We design the architecture for blockchain systems, selecting the right platform, chain and trust model for your requirements. We define onchain components, identity, custody, integrations, operating responsibilities, data flows and security controls. You get a target architecture, documented design decisions, delivery roadmap and cost and timeline ranges, with build-vs-buy recommendations where appropriate.

How it works

1
Define the decision
We agree what you have to decide, by when, and what evidence would be enough.
2
Assess the current state
We review your existing systems, constraints, teams and undocumented dependencies.
3
Compare the options
We evaluate blockchain and non-blockchain approaches, documenting the trade-offs and reasoning behind each option.
4
Test the critical assumption
Where analysis isn't enough, we build a technical spike or run a benchmark to validate it.
5
Design the target architecture
We draw components, data flows, trust boundaries and controls, and record the alternatives we rejected.
6
Attach numbers
We give you increments, dependencies, team shape, risks, and cost and timeline ranges.
7
Stay available
We can act as design authority, evaluate vendors, review implementation, and update the design as things change.

Frequently asked questions

What is blockchain solution architecture design?

The work of deciding how a system should be built before it is built: which platform, which trust model, which components run onchain, how identity and custody work, how it integrates with existing systems, and who operates it. LimeChain delivers it as a decision document with recorded alternatives and cost ranges, so the choices can be reviewed and challenged later rather than inferred from code.

Will LimeChain tell us not to build?

Yes, when that is the honest answer. A recommendation not to build, to buy instead, or to solve the problem with conventional technology is a valid and common outcome. LimeChain's architects test whether a decentralized component adds enough value to justify its operational complexity. Finding the answer early is cheaper than finding it after a build has started.

What do we actually receive?

A target architecture with system context, component and deployment views, data and transaction flows, trust boundaries and security controls; a record of the key decisions and the alternatives rejected; the results of any benchmarks or spikes; and a delivery roadmap with increments, dependencies, risks and cost and timeline ranges.

Do you need access to our existing systems?

Access to documentation, architecture, integration points and the people who operate them makes the output materially better, but full system access is not always required. LimeChain works within whatever your security policy allows and states clearly which conclusions are evidence-based and which are assumptions still needing testing. Sensitive material can be analyzed under a private-only model policy.

How is this different from a proof of concept?

An architecture engagement answers how the system should be built and what it will take. A proof of concept answers whether one specific technical assumption holds. They are often sequenced: architecture identifies the assumption that could invalidate the plan, and a short spike tests it. LimeChain builds those spikes inside the architecture engagement when analysis alone cannot resolve the question.

Can LimeChain stay involved after the architecture is delivered?

Yes. LimeChain can continue as design authority through delivery, support vendor selection and evaluation, review implementation against the agreed architecture, and update the architecture as requirements or external dependencies change. This is common where your team or a third-party integrator does the build and needs an independent technical counterpart.
