Blockchain
Distributed ledger technology, applicable where multiple parties need shared records without a trusted intermediary.
How ready this is, and for what
What it is
Understanding Blockchain
A blockchain is an append-only ledger replicated across parties, where entries are cryptographically linked. Enterprise applications use permissioned ledgers with known participants rather than public networks.
The technology solves one specific problem: shared record-keeping between parties who do not fully trust one another and have no acceptable central authority.
Why it matters
Genuine but narrow. Where a shared record between competing or independent parties is needed and no party can host it, distributed ledger is a reasonable answer. Where a trusted intermediary exists or a shared database would serve, it adds cost and complexity for no benefit.
Problems it addresses
- “Multiple independent parties need a shared record and no single party can host it.”
- “Supply chain provenance cannot be verified across organizational boundaries.”
- “Reconciliation between counterparties is manual and disputed.”
Capabilities
Feasibility assessment
An honest evaluation of whether distributed ledger is warranted — most often it is not.
Permissioned ledger implementation
Known-participant networks with defined governance.
Smart contracts
Automated execution of agreed multi-party logic.
Traceability solutions
Provenance across multi-party supply chains.
Use cases
Supply chain provenance
Verifiable chain of custody across independent organizations.
Multi-party reconciliation
A shared record reducing dispute between counterparties.
Feasibility assessment
Establishing whether a distributed ledger is warranted at all — most often the answer is that a shared database would serve better.
Before you commit
Prerequisites, governance and risks
The questions that determine whether this will work in your environment, rather than in a demonstration.
What has to be true first
- A genuine multi-party trust problem — this is the essential test
- Willing participants; a network of one has no value
- Governance model agreed between parties before implementation
Governance
The most valuable governance activity is the feasibility assessment that concludes a conventional database would be better. Network governance between participants — who joins, who validates, how disputes resolve — is harder than the technology and should be settled first.
Risks
- Applying it where a shared database would serve, at much greater cost
- Network effects — value depends on participation that may not materialize
- Immutability conflicting with data protection rights such as erasure
