Hi Is it possible somehow to prevent concurrent states updating from chaincode by putState? So, when I run two concurrent transactions (which update the same key) at the same time I want that the last

You may start configtxlator as a server, and invoke its functions as REST APIs. This is the preferred integration option for Node SDK -- see https://fabric-sdk-node.github.io/tutorial-channel-create.h

Hi, From Node SDK, is there anyway to get stdout from configtxlator as it is possible in shell ? It seems that the --output option can not be omitted using (child_process) exec. Thanks a lot for you h

Thanks for reply. I have tried passing in an outside function as a parameter for registerChaincodeEvent now it does not recognize it as eventCallback function and throws error like "eventCallback para

That is a general nodejs function, not specific for fabric. But AFAIK, you could use outside function and variable inside callback with `closure` pattern or even directly using the context scope. Best

yes, you maybe can not get the latest info about height. But if the channel is alive the height will not be static. There are always transactions around. I am not sure how much sense it will make to k

I have a same concern here, a proposed new feature to provide a more updated block height is expose a query service from orderer, instead of from peer. For who is current leader peer, I gues it could

As we know, one channel can have multiple peers, and when we query ledger height , we need to specify one peer in the channel, but if this peer's ledger is not up to date(e.g. not a leader peer, netwo
