  • Endorsement Policy
  • Metrics exposed by each peer via Prometheus

  • Raise Explorer to the powerful next level Ledger Data Query Platform 

    • Track historical operations for any specific state
  • Automatically analyzing schema of the ledger state

  • Continue on bug fixes, help community in configuring HLExplorer and troubleshooting

  • Integrate the additional features mentioned in the “Contributor Diversity” section into Explorer

Maintainer Diversity

We’ve had a few spot contributors added.  No new maintainers were added. We really need the community to come forward and contribute.

Please find here the maintainers list.  https://github.com/hyperledger/blockchain-explorer/blob/master/MAINTAINERS.md

Contributor Diversity

The current main contributors are from DTCC and Fujitsu. We have 4 unique contributors on   Github   in this quarter.

And we had some proposals for Hyperledger Explorer as below:

  • New contributions
  • EasyDoser
  • This is the outcome of one of the Hyperledger Internship programs. The integration of this feature into Explorer will offer more visibility of the network to users.
  • Ease endorsement operations for Hyperledger based products (EasyDoser)
  • LedgerDataRefiner
  • Fujitsu Lab. has proposed integrating their open-sourced ledger data analytics tool into Explorer. We have started the discussion on how to proceed with this contribution.
  •   https://github.com/FujitsuLaboratories/Ledger-Data-Refiner
  • WIP contributions
  • minifab
  • This project is offering Hyperledger Explorer support as one of their features and we think it will be a good mutual reference. 
  • hyperledger-explorer-made-easy
  • This is a kind of utility tool for the easy setup of Hyperledger Explorer. After evaluating this tool and having a consensus for merging it into the Explorer repo within the team, we might get it included in Explorer as one of the official features.

Additional Information

The insight chart can be found at   Explorer  stats for the last quarter .

From the project lifecycle

Projects seeking to graduate from  Incubation  must meet the criteria defined in the  Incubation Exit Criteria   document.

See the following from the  TSC Decision Log for example of projects that have requested moving to Graduated status:

Arnaud J Le Hors : Should we re-open  Move Hyperledger Explorer from incubation to active status  and have the Explorer community update this page? Or should we have them create a new decision log entry "Move Hyperledger Explorer from Incubation to Graduated status"?

I am in favor of creating a new page

Posted by tkuhrt at Jun 11, 2021 16:41

I agree, this will give us a cleaner track record.
