Shared state
Several independent parties need to verify the same state and accept changes under agreed rules. Who can participate and change those rules must be clear in advance.
← Offers & developmentDAPPS & BLOCKCHAINGood technology.
Good technology.
For the right use case.
Shared rules between independent businesses? Publicly verifiable digital states? We assess whether blockchain offers an advantage and build the right application. A conventional database may be the better answer.
From value to implementationFOUR QUESTIONS BEFORE CHOOSING TECHNOLOGY
A database is a good starting point.
When a responsible operator is accepted, permissions, versioning and a traceable log are usually simpler to implement centrally. A blockchain needs an additional, specific benefit.
Initial technical guidance. Your choices stay on this page and are not transmitted or saved.
WHAT A DAPP ISOne interface.
One interface.
Rules executed together.
A DApp connects a user interface to logic in smart contracts. Users confirm actions with a wallet, for example. The website, data sources and interfaces still need planned operations.
Digital evidence
Evidence should be independently verifiable. We compare anchoring it on a blockchain with simpler signatures and logs. Storing an incorrect input does not make it true.
Open integration
An application needs to work with existing smart contracts. We assess the network, interfaces, fees, key model and dependencies before considering a token of your own.

one-off, including 19% VAT- One use case, up to three participating organisations and one remote clarification round
- Comparison of a central database, signed evidence and suitable blockchain architecture
- Written recommendation with a data model sketch, cost factors and prioritised next steps
- One written follow-up round and a separately priced DApp prototype as a possible next step
Scope & requirements
Technical assessment using the process information provided. No smart contract audit or legal, investment or tax advice. Development, transaction fees, RPC services, hosting and external reviews are separate. A recommendation for a conventional database is a complete and valid outcome.
DApp & smart contract prototype
A bounded workflow on an agreed test network: interface, wallet connection, smart contract logic and integration with existing systems.
- Source code, automated tests and technical documentation
- Test permitted actions, key roles and failure cases explicitly
- Demonstration and acceptance against agreed requirements
Scope, price and schedule follow clarification. A test network prototype is not yet an application approved for real assets.
Request a DApp proposalReview & organised operations
Key management, responsibilities, monitoring, updates and emergency procedures become part of the operations plan. External security reviews are priced separately.
- Account for transaction costs and RPC providers
- Handle confidential content and erasable data separately
- Protect the frontend, indexer and integrations against outages
Limitations are part of the decision.
Transactions cost money, confirmations take time and published contract logic can only be changed using procedures prepared in advance. Wallets and recovery affect usability. Open networks do not automatically make your interface or external data sources resilient.
Technical background: Ethereum: DApp architecture, benefits and limitations. The project assessment also considers solutions without blockchain; legal questions and use with real assets require a separate assessment.
