Hello Laszlo, I would like to differ a bit. Orderer does not check for endorsement policy or endorsements. It just simply orders the transaction into a block which in turn becomes finality. Thus

yes, you maybe can not get the latest info about height. But if the channel is alive the height will not be static. There are always transactions around. I am not sure how much sense it will make to

I have a same concern here, a proposed new feature to provide a more updated block height is expose a query service from orderer, instead of from peer. For who is current leader peer, I gues it

First, if the format of the new channel config is allowed, there is not an easy way to operate like a roll back. But I think you can extract the previous version of channel config via parsing

Greetings, I have collected the name and email from everyone who has expressed interest in this effort. I would like to call one more time for people to respond to this call to be part of the working

Xiaohan, Thanks for asking, it was resolved a long time ago, around August 12 something. Cheers, Don (Don) Chunshen Li Blockchain Consultant / Hyperledger Fabric Application Developer

Hi, Don, Have you resolved this issue later? Thanks, Xiaohan Don Li <lichunshen84@...> 于2018年8月11日周六 上午10:22写道：

Angie, When you are invoking a smart contract, the smart contract defines the endorsement policy. Specifically it includes, which Peers, have to endorse the policy to make the transaction valid. In

Hi experts The fabric official document about "adding an org to channel" says we need to edit the config manually to add a new org. I worry it is possible to make the channel not work if there is any

Thank you , kindly confirm how is the consensus happens for the private fields in collections and how is it different from without collections. I believe Fabric does not have consensus on fields, is

Hi list members, I'm starting to have some fun developing blockchain applications in Node.js with Hyperledger Fabric. Here's a recent one that I put together

If you want peers from all organizations to validate transactions, you would use a single channel with N private data collections. The hashes are required for validation. If you want complete data

Jk, My attempt at your questions below. Anyone please correct me if wrong. 1. What is the best setup for a resilient network? How many orderers and peers should I have? Are 2 orderer pods

Hello Sanjeev Kumar, Hope you are doing good. Lucky to find someone facing the same issue. In the first network example, we have another script which adds 3rd organizatoin directly. run 1. ./eyfn.sh

Hi All, wondering if someone could help us with this error. we get this error when trying to send a proposal to a peer (using nodejs) E1206 17:31:05.562807000 140736009634688

Hi, I'm curious to know if anyone / any company has leveraged Hyperledger Fabric platform for identity theft / fraud prevention and/or simply called identity management. Along the same line of

Hi All - thank you for the valuable inputs. I have few related queries relevant to the answers :) - In my collection configuration I have just 3-4 Orgs (out of 25 total) having a chunk of the

There’s a hash of the private collection document stored on the ledger.

I have a simple fabric network with an orderer in solo mode and single peer connected. The network is used by two spring-boot apps, each of them using a separate channel. Both apps and fabric nodes

Hi, The Private Data stored in the transient DB until the Orderer validates the transaction. Then the private data only be stored in SideDB of a Peer. In the SideDB of only those Peers who have
