This workshop addresses the problem of transparency and traceability of data in supply chains. In the first part of the workshop, we will cover the theoretical background of blockchain technologies relevant for supply chains, and analyze potential applications. We will specifically address the potential application of blockchain in the context of tracking data in honey production, distribution and sales, with the goal to reduce forgeries and provide all stakeholders with access to data though the whole chain.

In the second part of the workshop we will presented how smart contracts between honey producers and certification authorities can be implemented on Algorand blockchain using PyTeal library in Python programming language (no previous knowledge of Python is needed). We will explain how smart contract actually works and its lifecycle. Example will also cover data types and main functions that can be used to interact with smart contracts.
