Part of Deeptech & High-tech
Blockchain and Digital Trust
Evaluate when a shared ledger helps, trace transactions and design a verifiable credential workflow. Build a local hash chain and an access-controlled registry model. This course teaches architecture and prototypes, not cryptocurrency trading.
Sponsored by InscientechObjectives
- - Compare a database, signed log and blockchain against a concrete trust problem.
- - Compute a hash, link records and explain the limits of local tamper detection.
- - Trace signing, validation, inclusion and finality without exposing private material.
- - Explain ordering, fault assumptions and governance choices.
- - Specify state transitions, permissions and failure cases for a registry.
- - Deliver a tested architecture with explicit off-chain responsibilities.
Prerequisites
Basic files, percentages and logical reasoning. Complete PY or demonstrate equivalent coding skills before the Python labs.
