Hello; could you give me some more info please about how you're sending transactions. Do you have the chaincode logs for example? Or post to rocketchat #fabric-chaincode-java and we can discuss

After upgrading to 1.4.4 i receive the following error in my chaincode logs: `transaction returned with failure: Failed to submit task for processing` I'm sending transactions in a multithread

I followed the tutorial “Adding an Org to a channel”. The new org works, but it does not seem to have an anchor peer defined. How should I update it to include definition of an anchor peer for

Remember that blockchains are decentralized ledgers. What you've done here is essentially tampered/corrupted your own local peer's state database so that it is not in sync with the blockchain blocks.

Dear Brett Logan, Thank for your answer, related to fine-grained access control by adding attributes to identity of the user I found that: 1. It might leak sensitive information of the user inside the

Hello Team, We have containerized an express app using fabric node SDK to interact with the blockchain network. We have deployed this alongside the fabric network on a single VM. While testing with

see this video: https://youtu.be/KOS5CeP-mNY Programming Hyperledger Fabric youtu.be the resolution is very poor but it contains the steps to repro the issue.

Something else must be going on, since what you've described is not possible. New blocks with validated transactions drive the CouchDB state database updates, never the other way around. Watch the

Summary: we created a simple Fabric network that comes with the IBM Blockchain extension and uses CouchDB and one peer and one orderer. we made some chaincode invocation requests and created some data

It was not really a Node SDK limitation but rather a node-gyp issue. We require node-gyp as we use native modules. The latest versions of npm ship with versions of node-gyp which support Python 3.5,
