Blockchain architecture in Smart Pedagogy offers valuable social propositions like trust, identity, transparency, immutability, smart contracts and disintermediation.There are multiple practices how to record learners' achievements and present learning transcripts where the most common practices are university issued diplomas and vendor issued certificates.There are social networks which allow users to publish their learning achievements for possible stakeholders; however, the common problem is to verify if published diplomas and certificates are valid.This study experiments with lifelong learning transcript called knowledge passport in blockchain architecture.The proposed scenario allows learners to publish evidence of their learning achievements in desired formats connected with blockchain network for instant authenticity verification.The experimental network consists of three nodes where one is located in Latvia, the second -in the USA, and the third -in Asia.Based on the proposed implementation, such approach much better validates learning evidence, eliminates knowledge passport fraud and reduces organizational workload overhead for stakeholders involved in verification of documents certifying a person's knowledge.
