For posterity: it turns out the boot process was failing on the peer nodes (revealed by examining logs of the failed docker containers); I solved this error (and a few previous errors by adding `GODEBUG=netdns=go` to the environment for the `cli` and `peer` nodes. Not sure what this does (yet) and not sure why my setup didn't work out of the box.

Hello everybody. We are understanding this sample project: https://github.com/hyperledger/fabric-samples/tree/release-1.1/fabric-ca but its bringing some concerns. Apparently the setup script brings up the orderer and also creates a bootstrap channel, but the run script creates another channel with that same name. It is not really clear what is the flow of those steps, should we create all the channels at orderer and sync them ourselves to the rest of the peers or is the right way to create it again after orderer bootstrapped?

Hi everybody, someone can post a sample configtx. yaml for the sample first network with the ACL lines needed to add a new organization into the channel with only a specified organization member signature? Without a majority of signatures as default. I have tried to put "OR ('Org1MSP. member')" at several levels of configtx. yaml on the first network sample (1.2.0) using hints from https://github.com/hyperledger/fabric/blob/master/sampleconfig/configtx.yaml. The objective is that Org3 can get into the channel with only Org1 approval. Thanks a lot.

In the chaincode example, marbles has a gethistoric function but I did not like it. What I've seen and what really looks cool and hyperledger explorer, it connects a front end to a backend and peer listener, monitoring all the events that happen and showing it in a dashboard. I'm in the process of implementing it for, using features of it in a new front end.

Hi I have couple of queries - 1. Private Data collections - I could not find private data history , GetHistoryForKey - returns only public data Note: i am using public data as normal ledger , whilst only private data as Collections 2. Is there any way i can find say recent 10 blocks from ledger, i dont see any API for it. The one we have is getBlockByTxID , which become quite tedious , since first we need to invoke transaction history and then invoke for each one of them to get Block . Any simpler way to this ?

dave.enyeart (Fri, 24 Aug 2018 10:08:13 GMT):
@nukulsharma The API for getting history of private data is not available yet... it will become available in an upcoming release, you can track it's progress here: https://jira.hyperledger.org/browse/FAB-5094.To get the last N blocks, you can use the event service, read about it here: https://fabric-sdk-node.github.io/tutorial-channel-events.html

Hello. I've recently begun Blockchain development. I have a doubt regarding the Fabcar chaincode (https://github.com/hyperledger/fabric-samples/tree/release-1.2/chaincode/fabcar/go)... When I try to install and instantiate the chaincode using the cli container, I am facing unmarshalling errors during the instantiation. It is highly likely that I am not passing the arguments in the command line correctly. How do I modify the line "peer chaincode instantiate -n mycc -v 0 -c '{"Args":["a","10"]}' -C myc" to get my Fabcar chaincode to work? Thanks.

Hi all, Am new to fabric and have gotten started with the fabric-samples directory and have created the first-application and first-network. However, I'm unable to create a private collection (as per section 4.5), something breaks down with orderer-peer communication and channel does not create or can instantiate chaincode. Thus I'm wondering if anyone can point me to a working repo (github or otherwise) where a simple application has been demoed with private collection feature. It is critical for my use-case but its the one thing thats not working. Simplest configuration will suffice- 1 org, 1 peer network.

dave.enyeart (Mon, 15 Oct 2018 11:10:09 GMT):
The private data tutorial uses the first-network docker network. The private data aspects do nothing to interfere with the CLI-peer-orderer communication. I'd suggest to re-clone fabric-samples in a new directory and utilize the instructions that are known to work:

sheetal-hlf (Tue, 16 Oct 2018 09:48:47 GMT):
Couple of questions on Private Data 1. Does requiredPeerCount attribute in Private Data depend on the endorsement policy of chaincode? for e.g. if endorsement policy is -P "AND('Org1MSP.member','Org2MSP.member')" then requiredPeerCount=2 if endorsement policy is -P "OR('Org1MSP.member','Org2MSP.member')" then requiredPeerCount=1 2. Also if I want multiple orgs to endorse the transaction then they must have access to Private Data if endorsement policy is -P "AND('Org1MSP.member','Org2MSP.member')" then policy for private data must be "OR('Org1MSP.member', 'Org2MSP.member')" Any comments are appreciated.

I'm trying to create or load a marbles private collection example using or that uses the node sdk. I'm not finding any good repositories or examples. The fabric-sdk-node.github.io is not as helpful as fabric documentation. ANyone can help me find a working demo (i need api access thus node sdk and I need private collections working, thus marbles)- anything else similar would also help.

I have made modifications to the fabcar.js (contract) in the FabCar example, but the changes are not reflected when I query the ledger afterwards. As of now, I have come to know that I need to install & upgrade the chaincode. So how can we do that? Plus, I have tried running the following command: "docker exec cli peer chaincode install" on the terminal but I get this error "Error: error getting chaincode code fabcar: path to chaincode does not exist: /opt/gopath/..fabric-samples/chaincode/fabcar/javascript/lib" What am I doing wrong?

[ ](https://chat.hyperledger.org/channel/fabric-samples?msg=dNRMgegA7ApWh9EFc) @DawoodJehangir You have the correct approach - just an error in the path name ... The first time you `install` and then `instantiate`, the second time you `install` then `upgrade` The path name you specify is the pathname *within* the cli docker container, so the path you want is likely to be `/opt/gopath/src/github.com/fabcar/javascript/lib` You can verify it first by looking at the folder in the container `docker exec cli ls /opt/gopath/src/github.com/fabcar/javascript/lib`

rthatcher (Fri, 22 Feb 2019 11:55:04 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-samples?msg=Y7rT56snuaNtYbqvd) @DawoodJehangir Goods news that the install worked. The upgrade command will be something like: `peer chaincode upgrade -n fabcar -v 1.1.0 -l node -c '{"Args":["initLedger"]}' -C mychannel` Note that you should have changed the version number in the `package.json` before the install and it is this new version number you use on the upgrade command.

DawoodJehangir (Fri, 22 Feb 2019 12:10:44 GMT):
@rthatcher Thanks for your help. One thing that I'd like to mention is that I didn't change the version number in package.json. I only changed it in the command "-v 1.0 => -v 1.1" and it worked correctly. The modifications in the Init Ledger are being reflected now. Is there something wrong if we don't change it in package.json?

[ ](https://chat.hyperledger.org/channel/fabric-samples?msg=G5BPgy5y8HrsnPyFr) @richzhao I have just worked through the steps up to and including instantiate on my test VM - so it looks OK to me - can you share some information on your environment etc: 1. What OS are you using (I have Ubuntu 18.04) 2. What version of docker and docker compose? 3. Can you show output of `docker ps -a` command 4. Can you show the output of the peer container (starting with the line "[lscc] executeInstall -> INFO 03b Installed Chaincode [papercontract] Version [0] to peer") It is possible the problem was a temporary connection problem to dockerhub - have you retried the instantiate command?

@richzhao please can you send the next few lines of your peer log - or post the whole thing somewhere where I can grab it. Also are you seeing any errors in the couchdb log? Can you show output of docker images command ?
