Blockchain and its underlying distributed ledger technology seems a perfect fit for organizations seeking to enhance transactional security, speed up processing and reduce infrastructure costs via a federated system that verifies the transacting parties without a central authority. With its open, consensus-driven and shared system, blockchain eliminates traditional trust tropes such as paper trails and proposes a faster, more secure and instantaneous throughput of transactions. It fosters trust via a shared version of truth — a distributed ledger, accessible to all participants, that cannot be altered without a consensus.
However, to deliver on its promise, the distributed ledger must be assured from a business process and technology standpoint. This requires the verification of underlying preset conditions, encoded as business logic, for a syndicated network of nodes to authenticate a transaction. Data immutability, integrity and interoperability in a blockchain network are crucial, as well as its performance and security.
As a result, a QA strategy is hypercritical for organizations seeking to move blockchain from proofs of concept and pilots into everyday production.
