Welcome Haibo Yang and haoyu li : create wiki account, join github id to hyperledger team → cello org. https://github.com/hyperledger/cello
LFDT is revising the charter for each project. Please help review and see if there's any comment:
feng yang suggest revise the creating peer node API:
- Only create one peer with the specified name
- Yuanmao Zhu will help fix the issue
feng yang suggests:
- When downloading channel config, remove the hint of downloading succeed
- When creating channel, no need to edit orderer nodes
- When updating the channel (add an org), why need to input the msp_id? Need to update the steps into docs.
Haibo Yang Intern plan: Project Plan - Decentralized Blockchain Network Operation Dashboard
- Docker image for HLF v2.5 (latest is v2.5.9): update all required images
- https://github.com/hyperledger/cello/pull/627: Suggest upgrade node.js to 20+, lots of changes are needed.
