  In this research, the evolution of Distributed Ledger Technology (DLT) in
supply chains has been mapped from the inception of the technology until June
2020, utilising primarily public data sources. Two hundred seventy-one
blockchain projects operating in the supply chain have been analysed on
parameters such as their inception dates, types of blockchain, stages reached,
sectors applied to and type of organisation that founded the project. We
confirm generally understood trends in the blockchain market with the creation
of projects following the general hype and funding levels in the industry. We
observe most activity in the Agriculture/Grocery sector and the
Freight/Logistics sector. We see the shift of market interest from primarily
private companies (startups) to public companies and consortia and the change
in blockchain adoption from Ethereum to Hyperledger. Finally, we observe higher
success and lower failure rates for Hyperledger-based projects in comparison to
Ethereum-based projects.
