Blockchain & Web3

Practical uses for blockchain and Web3.

Traceability, smart contracts, verifiable identity and digital assets: we support you from selecting the use case to integrating it into your information system.

Start with your business need

Sharing information between partners, verifying a credential, tracking an asset or establishing shared governance: we start with your business objective. We compare blockchain and Web3 approaches with the alternatives, then assess their value against your costs, constraints and users’ needs.

Our approach brings together technical design, user experience and the rules governing participation. Your teams gain a shared basis for making decisions, experimenting and preparing for operation.

What we offer

  • Enablement and scoping — give leadership and technical teams a shared understanding, assess use cases and document the investment decision.
  • Architecture and smart contracts — compare public chains, permissioned chains and layer 2 solutions; design and test smart contracts, and prepare their security review and an external audit suited to the risks.
  • Traceability and certification — design the tracking of physical or digital assets, specifying data sources, responsibilities and checks between the real world and the ledger.
  • Identity and digital assets — explore verifiable credentials, decentralised identity and tokenisation, working with legal and finance teams to assess their implications.
  • Governance and user experience — define roles, permissions and decision rules, including for decentralised autonomous organisations (DAOs), and design accessible journeys with an integrated digital wallet.
  • Integration and operations — connect the solution to your information system and establish key management, monitoring and operating procedures.

From scoping to implementation

  1. Assess the opportunity — clarify the problem, participants, alternatives and success criteria. The deliverable: a reasoned recommendation and a prioritised scope.
  2. Test the use case — build a prototype and evaluate it with users against integration constraints and security requirements. The deliverable: measurable results to inform the next decision.
  3. Prepare for production — define the target architecture, governance, controls and operating plan, then support implementation and the handover to your teams.

Examples of possible engagements

  • An opportunity study and traceability prototype for an agri-food supply chain.
  • A verifiable credentials scheme for a certification body.
  • A prototype journey with an integrated digital wallet and an assessment of a tokenisation model.
  • Integration of a permissioned ledger and smart contracts into an existing information system.
