Brett
Thanks for the quick response. I did go through the PR, seems like an excellent addition. May I ask a simple question?
If you use REST API for osnadmin, you would need to supply the ca-cert,client-cert and client-key. How do you plan to accept these for the API? This would be very helpful in cases where you cannot depend on the CLI? Would be very grateful for any pointers/tips.

Re: Fabric 2.0: commit readiness returns false but approvalformyorg returned success

Manindra Singh
 

Hi Nikhil,

In response to your following comment, I re-ran the commit readiness command with those options but still get the same result:
"I do not see the following parameters on the commit readiness command: --init-required true --signature-policy "AND ('Org1MSP.peer','Org2MSP.peer')" "
Command: peer lifecycle chaincode checkcommitreadiness -o orderer.example.com:7050 --channelID allarewelcome --tls --cafile $ORDERER_TLS_CA -name sacc --version 1.0 --sequence 1 --init-required true --signature-policy "AND ('Org1MSP.peer','Org2MSP.peer')" --output json

Output:
{
"approvals": {
"Org1MSP": false,
"Org2MSP": false
}
}

Hi Chris,

In response to your following comment, please find the result of querying installed chaincodes, $CC_PACKAGE_ID on Org1 peer(same result comes for Org2 peer also):
"If you query the peer for installed chaincodes, what is the output?
You are using a variable export ($CC_PACKAGE_ID) to represent the packageID. Please note actual value of $CC_PACKAGE_ID and make sure it matches the one in your output (in this instance from your log below...sacc_1.0:5562f868f6fd43ff8873f403aa52bc6928161fec933065d0b81e2193f6038bd0)"

Re: Fabric 2.0: commit readiness returns false but approvalformyorg returned success

Manindra Singh
 

Hi,

I have a network of 2 orgs - Org1 and Org2. I am getting the same error when checking commit readiness using following even though I ran approveformyorg on both Orgs:
Command: peer lifecycle chaincode checkcommitreadiness --channelID allarewelcome --name sacc --version 1.0 --sequence 1 --output json
Output:
{
"approvals": {
"Org1MSP": false,
"Org2MSP": false
}
}

Executed the approveformyorg command on both Org1 and Org2:
Command: peer lifecycle chaincode approveformyorg -o orderer.example.com:7050 --tls --cafile $ORDERER_TLS_CA --name sacc --version 1.0 --channelID allarewelcome --sequence 1 --package-id $CC_PACKAGE_ID --init-required true --signature-policy "AND ('Org1MSP.peer','Org2MSP.peer')"
Output for Org1:

Similar output for Org2 also. As mentioned by Siddharth, signature policy is also specified in approveformyorg command but still getting the same issue. Can anyone help with anything else that is missing? Please let me know if I need to provide any more details.

Questions when using API Server

Deok Youb Kim
 

I compose the system with the following structure.

Mobile App <-> Api Server <-> Fabric Network(Peer, Orderer)

I want to manage the user's key and certificate in the mobile app. In this case, what should be done when invoke and query?

For example, when performing a query, QueryByChaincodeRequest is created in the Mobile App, and after passing it to API Server, the API Server wants to perform Query using the MSP information of the user. This is because I want to manage the user's key only in the Mobile App.

I make QueryByChaincodeRequest in Mobile App and try to deliver it to API Server using Serialized, but QueryByChaincodeRequest doesn't seem to be serialized.
Also, the UserContext inside QueryByChaincodeRequest contains the user's key and certificate information, so it seems that this is not what I want.

Is it possible to construct this way? I wonder how to do it.

Thank your help

Hyperledger Fabric with SoftHSM2 #fabric #hsm

pchomsinsap@...
 

Hi I have been trying to get Hyperledger Fabric (v2.0.1) to connect to SoftHSM2 (v2.5.0), but haven't been successful at that. The main purpose is to create a secret key for symmetric encryption/decryption and securely store the key inside the SoftHSM2. I plan to send unencrypted data from the Fabric smart contract to be encrypted by SoftHSM2 and send back to smart contract to be stored on blockchain ledger. Likewise, I plan to send encrypted data from blockchain to be decrypted by SoftHSM2 and unencrypted data back to smart contract then the users.

My issue is when I package my chaincode and invoke smart contract method, Fabric is not able to find the file with .so extension. In my case, the file is libsofhsm2.so. I've tested my code outside of Fabric to make sure that key generation, encryption, and decryption functions work.

Should I try to package Fabric chaincode manually into the .tar.gz file? Would that be an correct approach? I first thought that Fabric smart contract would be able to locate external file on my computer but maybe I was wrong? I have also looked into configuring Fabric to use PKCS11 but wasn't successful (https://hyperledger-fabric.readthedocs.io/en/release-2.0/dev-setup/build.html?highlight=softhsm2). I thought that this configuration is for Fabric to store user private keys in SoftHSM2 but all I want to store is a secret key which is separate from this. I don't know if this is relevant but the smart contract is written in Javascript instead of Go.

Any help or suggestion would really be appreciated. Thank you!

Getting block data in a user chaincode #hyperledger-fabric #qscc

@secure12
 

Block data can be retrieved invoking the QSCC using its, e.g. GetBlockByNumber(), functions. However, qscc cannot be invoked from other chaincodes (line 96 of https://github.com/hyperledger/fabric/blob/master/core/scc/qscc/query.go).

Is it possible for user chaincodes to get block data, either directly from the ledger or using QSCC?

I know it is easy to get blocks using the SDK, but we would like the block data be used to ensure consistency between most peers' ledger, so we reckon the block retrieval should be done in the chaincode level.
Why cannot do range query on composite key? #fabric #fabric-questions

Yueming Xu
 

I see that fabric-chaincode-go implementation limits GetStateByRange to only simple keys. However, it would be nice if I can get a set of composite keys by range and then fetch corresponding state data by using the state key embedded in the returned composite keys. 


Is this a limitation of how composite keys are implemented, or is it a limitation of the fabric-chaincode-go package only?
Re: Hyperledger Fabric Operator

DAVID VIEJO POMATA
 

Hello again,

We released a new version of the Hyperledger Fabric Operator which includes:
  • New Kubectl plugin to create a network with a few commands
  • Parametrization for the peer and ordering service

If there is any doubt, please let me know :)

Regards.

Why does only the first peer report TLS handshake errors? #tls #docker-compose #fabric-questions

chin-kai.ong@...
 

I am trying to deploy a three-orderer two-peer network in Docker swarm, but somehow I keep seeing TLS handshake errors logged in only the first peer.

I'm working with Fabric 1.4.9, and these are the commands I run:
1. cryptogen generate --config=./crypto-config.yaml
2. docker stack deploy --compose-file=docker-compose-orderer.yaml fabric
3. docker stack deploy --compose-file=docker-compose-peer.yaml fabric

Please let me know if there's any other information that I should add to this post. I'm really not that familiar working with Fabric, and I've spent days trying to resolve this but I don't know where to look.

Network Hardware Requirement

q p <arthus.dot@...>
 

Hello there, I wanted to know if there is a document somewhere about the question of hardware requirements for a network, for example RAM, type of disk, bandwidth for one peer, for one orderer etc etc..

Thank you in advance
