+# Working with BFT Orderers
+
+This guide explains how to run `test-network-k8s` with the BFT consensus type.
+
+In the current `test-network-k8s`, a Fabric network with three orderers managed by Org0 is started when using the Raft consensus type. In contrast, when specifying BFT, the network starts with four orderers (`org0-orderer1`, `org0-orderer2`, `org0-orderer3`, and `org0-orderer4`) with the BFT consensus type.
+
+## Running Peers and BFT Orderers, Creating a Channel
+
+Since BFT Orderers are supported only in Fabric v3.0 and later, you must specify `3.0` or later for the `TEST_NETWORK_FABRIC_VERSION` environment variable. Additionally, set `TEST_NETWORK_ORDERER_TYPE` to `bft` to start the Fabric network and create a channel with BFT consensus type. For example:
+
+```shell
+export TEST_NETWORK_FABRIC_VERSION=3.0
+export TEST_NETWORK_ORDERER_TYPE=bft
+
+./network kind
+./network cluster init
+./network up
+./network channel create
+```
+
+The `configtx.yaml` template used for constructing the channel genesis block with BFT consensus type can be found [here](../config/org0/bft/configtx-template.yaml).
+
+## Deploying and Using Chaincode
+
+After creating the channel with the BFT consensus type, you can deploy and interact with chaincode. For example:
+
+```shell
+./network chaincode deploy asset-transfer-basic ../asset-transfer-basic/chaincode-java
+./network chaincode invoke asset-transfer-basic '{"Args":["InitLedger"]}'
+./network chaincode query  asset-transfer-basic '{"Args":["ReadAsset","asset1"]}'
+```
+
+## Troubleshooting
+
+If you encounter issues, try the following troubleshooting steps.
+
+First, run the following command to verify that the environment variables are correctly applied and that the Fabric image and binary versions match:
+
+```shell
+$ ./network
+
+Fabric image versions: Peer (3.0.0), CA (1.5.13)
+Fabric binary versions: Peer (3.0.0), CA (1.5.13)
+
+--- Fabric Information
+Fabric Version          : 3.0
+Fabric CA Version       : 1.5
+Container Registry      : hyperledger
+Network name            : test-network
+Ingress domain          : localho.st
+Channel name            : mychannel
+Orderer type            : bft
+
+(...)
+```
+
+If old Fabric binaries or network artifacts remain, they may cause issues.
+In such cases, clean up the environment using the following commands:
+
+```shell
+./network down
+./network unkind
+
+rm -r bin
+```
