Hi Fabric Community, the FPC Team is happy to announce a new release of Fabric Private Chaincode -- a framework built on (unmodified) Hyperledger Fabric to enhance data confidentiality for

It looks like you are using legacy chaincode. 'Upgrade' is a transaction on the channel, therefore you only need to do it once for the whole channel, not per peer or per organization. Dave

Hi Team, I have two organizations and two peers each. For some reason, we just upgraded only one peer in each organization (but installed chaincode all peers). Now I need to run all 4 peers but I have

If you update the corresponding 'parent' prefix for every transaction, you could just write it every time instead of read/write. You only receive conflicts when you read/write. e.g. write four records

Yes, that's right. Note that you can update N key/values in the 2nd transaction, if you have such a need. You don't have to update them one at a time. Dave Enyeart "Tomás Peixinho" ---02/08/2021

This could be solved by the following approach: https://www.github.com/hyperledger/fabric-samples/tree/master/high-throughput Basically, you could store all the request as it is, in its own key. Then

Thank you for your feedback, Dave! I see the value of the ranged queries now, that actually makes sense, I hadn't thought about it. It just doesn't serve me very well. However, your idea to separate

Dear Tomás, Have you seen this? Please review the following - perhaps you need to craft the solution to the problem slightly differently and side step the implementation

I don't think it's possible in my project (this is my master's thesis, the idea was defined like this by my thesis advisors, who don't know much about blockchain technology). But I can be more

There is no ability to turn off the phantom validation. The idea behind range queries in update transactions is that you would scope them to a set of keys that you expect won't be updated

Is it possible for you to diversify the range query you would be using? For example: Let's say there are 3 clients, each client can have a namespace in ledger and are only able to update keys in

Good afternoon, I'm developing an application using Hyperledger Fabric that requires me to, in order to do an insertion on the blockchain, check a lot of the stored keys, so that it can know which one

Thanks - Andy Hurt has replied to the comment on stack overflow. Matthew White

Hi Tsvetan, Thanks for that clarification. In fact, that is our ideology also where we're saying participating organisations joining the network can decide whether or not they want to run their own

Hi Samyak Jain, My last point is regarding the technical network layer (not the fabric network). Let's assume there are multiple organizations that each has fabric nodes. From technical networking

Hi Samyak Jain, I expect many of the networks to be hybrid deployments running on very heterogeneous infrastructure and communication over internet is essential (just make sure TLS is always

Hi Community, this is my first time deploying chaincode to a fabric network and I'm fairely new to golang. Right now I'm trying to create a system where a patient can create a permission for a doctor
