The aim of this thesis is to explore existing post-quantum algorithms in the implementation on blockchain technologies. The choice of which blockchain to study fell on on a project founded by the Linux Foundation in 2015. A non-profit association profit and the largest open source organisation in the world. Such a project by the name of Hyperledger Fabric, is open source and is considered the modular blockchain framework for enterprise blockchain platforms. We will then replace the cryptographic primitives vulnerable new post-quantum algorithms, which are resilient and secure to a possible future advent of quantum computing. The first phase concerns the analysis of the Fabric framework by thoroughly understanding its mechanics and identifying within the various use cases where public key ciphers are used.
