Warranty Repairs: How Multiple Companies Can Stop Disputing Status Updates
A customer takes a laptop in for warranty repair. The retailer says it handed the device over to the service center on Tuesday. The service center claims it only received it on Thursday. The manufacturer can see only a record of the repair approval. How can they determine where those two days were lost?
For several independent companies, a shared record can be useful, with each handover confirmed by the party responsible for it.
A supplier sees one part of the process, a contractor sees another, and a bank or platform operator sees a third. When a dispute arises, the parties have to gather correspondence, compare document versions, and determine which record was created first.
Such processes need a shared, verifiable layer that allows participants to keep using their own systems.
What Is Worth Recording?
There is no need to move all documentation onto the blockchain. A more practical approach is to record only the key events that multiple parties need to see.
For example: a contract is confirmed, a request is accepted, goods are handed over, work is completed, a status changes, or a transaction is approved.
Each record shows what happened, when it happened, and which participant confirmed the action.
Participant Permissions
A shared history does not mean everyone has the same level of access.
A system can assign different roles: one organization creates a record, another confirms it, and a third is only allowed to view a particular status.
For critical operations, multisig can be used to require approval from multiple participants before an action is executed.
Transparency Without Exposing Everything
Verifiability does not require publishing commercial documents, personal data, or internal correspondence on a public blockchain.
Identifiers, hashes, statuses, or records of specific actions can be stored on-chain, while the documents themselves remain in corporate systems.
This gives participants access to a shared history while keeping sensitive information outside the public blockchain.
Integrations Matter More Than a Separate Interface
A practical enterprise solution should integrate with existing CRM and ERP systems, customer portals, and internal services.
APIs allow relevant events to be recorded on the blockchain automatically and their statuses to be retrieved. Employees do not need to manually duplicate every action in a separate blockchain application.
Where Decimal Fits In
DecimalChain provides the core components for these use cases: transactions, tokens, multisig, EVM smart contracts, APIs, SDKs, and a blockchain explorer.
Each project determines which events need to be recorded, who is authorized to create them, and which data must remain off-chain.
The main value of a shared history emerges when several companies need to verify the same confirmed event without constantly reconciling records across different databases.
