Many people utilize JSON format for assets stored on the ledger, the order items can therefore be a JSON array. Just be careful to utilize deterministic JSON marshaling in your chaincode, as described

Hi , I am trying to map assets from Hyperledger composer to Hyperledger fabric V2. In Hyperledger composer, there is model defined in .cto file, where I can have, e.g. asset Order identified by orderN

Hi, If you want to get the next bookmark then the below code example should work: ``` const temp = await ctx.stub.getStateByRangeWithPagination("", "", pageSize, bookmark); // bookmark to get the next

As far as I know, a contract is an instance class with the contract annotation. When does the Fabric runtime instantiate the contract class? When does the instance get disposed? From my experience, if

From what I understand, only "query" (read only) transactions work cross-invoking in different channels. If state is modified by chaincode, then channel has to be same as callers chaincode. In the exa

It's less about a race and more about consistency. (A race can cause an inconsistency.) Imagine that when you run the contract on peer one, the sequence observed by the ledger is ["data1", "data2"]; o
