Re: Can chaincode send multiple events in one transaction?
This is the correct behavior. There is only space for a single event. For examplehttps://github.com/hyperledger/fabric-chaincode-go/blob/2d8992/shim/stub.go#L26
We can see the implementation

Can chaincode send multiple events in one transaction?
Hi All,
I'm trying to send multiple events from my Go chaincode using SetEvent(). I use NodeJS' registerChaincodeEvent() to subscribe events.
I can receive an event from chaincode correctly if I emit

NodeSDK Get Latest Orderer Config Block
Hey guys,
I'm having trouble getting the latest config block from the orderer
so I can send it to a joining orderer that was added to the system-channel.
I'm using the getChannelConfigFromOrderer()

Trying to instantiate chaincode, and due to PANIC error on PEER0, and peer crashes.
Impossible to instantiate chaincode, because PEER0 crashes doing the process.

Re: #hyperledger-fabric Problems after peer channel update: PANI 044 Cannot commit block to the ledger due to config currently at sequence 0, cannot validate config at sequence 2
#hyperledger-fabric
The same panic error occur when I do, in sequence:
1) peer channel create
2) peer channel join
3) peer channel update , using AnchorPeer.block
I attach here the entire log of CLI, PEER0 and ORDERER,

Re: Forks and World State
Each peer logs its block commit hash every block at INFO level. The block commit hash is a hash over all valid transactions that are written to state database. So you can compare block commit hashes

Forks and World State
I saw that if the OS is malicious then a fork may happen by sending different peers different blocks. Is that detectable?
If a client made a query to the world state would that be subject to any

Re: One Org - Multiple MSPs & Channels
Well, if you don't define bootstrap peersand you have no anchor peers then the conditions to establish membershipbetween peers are not met, thus peers will not disseminate blocks to eachother.

An org? Sure.
A peer? Well maybe, if you don't useany bootstrap peers or anchor peers so gossip isn't used.

It is true that you'll see higher throughput if you load balance endorsement requests across multiple peers. You likely want multiple peers per org anyways for HA purpose.
I suspect that error message

Re: One Org - Multiple MSPs & Channels
I just saw a few research papers - seems they can be constructed.
But can an org handle thousands of channels?

Re: One Org - Multiple MSPs & Channels
local collections would be nice to use but the business level need to is to completely hide the txn data (ie even that it exists to other members). I did not know anonymous endorsements were viable.
