TitleCreation of a functioning blockchain explorer for Hyperledger Sawtooth



Blockchain is a back-end technology. However, for many of ScanTrust’s customer projects, customers still want a way to be able to “see” what is happening in the blockchain.  They want to see the blocks being created, transactions committed, and ideally be able to make sense of what is inside the transaction. For this you need a blockchain explorer.  

In our vision, the explorer is an application that both listens to events happening inside the blockchain (via websockets) as well as calling the sawtooth API, with an intuitive front-end for the user. The ideal explorer would be generic across sawtooth installations, but extensible by developers to add understanding of the customer data in the transactions (since it is often in a binary format) for display.  

ScanTrust uses Hyperledger Sawtooth for several customer projects. The task of the intern would consist of creating a generic blockchain explorer for Hyperledger Sawtooth that ScanTrust will be able to use in current and future customer projects. This means that the intern will use a front-end framework to build an application that listens to ScanTrust’s existing Sawtooth infrastructure.
