The Cosmos SDK and the Tendermint codebase have just been updated to patch a security flaw discovered recently. Consequently we have updated the ki-tools to account for this patch and these new versions. We provide hereafter a quick tutorial on how to update the Kazeki validators:

Step 1 :

Fetch the last version of the ki-tools with:

git pull origin master

Step 2 :

Re-install the ki tools by running

make install

Step 3 :

Relaunch your node. This step depends on your setup. Generally you can send a kill signal to the kid process as follows using

kill <pid>

where <pid> can be fetched with :

ps ax | grep kid

Once stopped the node can be restarted with the command:

kid start — home ./kid.

Make sure to run this command in your node home directory where your kid/ and kicli/ folders exist.

We encourage all the validators on the KiChain testnet to update their validators to this latest version as soon as this post is published.
