Install Node Keys

Tue, 10 Nov 2026 10:00:00 +0900

1. Install the nodekey and bls-nodekey into the data directory. The nodekey is the private key of your node, and the bls-nodekey is the BLS secret key used for consensus. Put the nodekey and bls-nodekey files you generated with keytool into the data directory (DATA_DIR=/kaia/kcnd/data). Warning Install both keys before starting kcnd. If kcn cannot find a nodekey in the data directory, it does not stop: it generates a new nodekey (and derives a new bls-nodekey from it) and runs with that identity instead of yours.

2. Modify data/log directory, network, discovery, boot node, reward base and log level information. 1) Your kcnd.conf should be modified as shown below. ** kcnd.conf is located at /etc/kcnd/conf/kcnd.conf for Option 1 (Yum Repo), and /kcn-linux-amd64/conf/kcnd.conf for Option 2 (Archive). Please change the path of the egrep command below for Option 2. $ egrep "^NETWORK|^DATA_DIR|^LOG_DIR|^VERBOSITY|NO_DISCOVER|BOOTNODES|REWARDBASE|ADDITIONAL" /etc/kcnd/conf/kcnd.conf NETWORK="mainnet" NETWORK_ID= VERBOSITY=1 DATA_DIR=/kaia/kcnd/data LOG_DIR=/kaia/kcnd/logs NO_DISCOVER=0 # setting 1 to disable discovery BOOTNODES="kni://b286e4140aea469992146c299f8915e34d59a014c29a045de41e578014761114176f42dece34a54ce1e37f92ab981fe1bb14e54fe23576e1182778c40e6272a2@ston146.node.kaia.io:32323?ntype=bn,kni://a6b61ee786952e3f8b681867d2535485622e80d0b9b7b89f26b2c631e59a4246b5f879487fbde7c324c3308ece0cdb1d7738430bdffce4f7f8c4f5a09eef80a3@ston738.node.kaia.io:32323?ntype=bn,kni://b25838727eb6b4631c8f8910b4f6376fe28041f251ee21129078a61d18d62d0dc2601be5a97eab8bdb5772309f861fddb7192935483813ef20e5716a34266f16@ston903.node.kaia.io:32323?ntype=bn" REWARDBASE="" # ADD YOUR REWARDS ADDRESS GENERATED BY KEYTOOL ADDITIONAL="--state.trie-cache-limit 5000 --state.live-pruning --vmodule blockchain=3"

Log Shipper Configuration

5. Configure the log shipper (Fluent Bit) The kcnd log is shipped by Fluent Bit, a separate process from Telegraf. Whatever happens to log shipping, Telegraf metrics and the kcn process are not affected. 1) Install Fluent Bit Fluent Bit’s official installer detects your distribution and sets up the repository itself. $ curl -fsSL https://raw.githubusercontent.com/fluent/fluent-bit/master/install.sh | sh $ /opt/fluent-bit/bin/fluent-bit --version 2) Create /etc/fluent-bit/kaia-logs.conf This file holds the log shipping configuration. Replace with the same value as hostname in /etc/telegraf/telegraf.d/kaia.conf (e.g. abc-cn).
