Before You Install
Before installing the Kaia package, it is required to create the associated node information to enroll your node URIs. The Kgen package is provided for CC operators, please follow the steps in the order shown below.
- Download
kgen
Package - Node Key & Node URI Creation
- Node URI Enrollment
Download kgen
Package
First of all, you can download the latest version of kgen
package depending on your operating systems on Download page.
You can find the kgen
binary file under the bin
directory.
Node Key & Node URI Creation
The node key and the node URI are created only once at the beginning. The node URI must be shared with other Core Cells of the Core Cell Network. A CN connects to other CNs and a PN connects to a CN and some PNs using the created node URI. A node URI is created based on the node key by using the downloaded kgen
. The below command line creates nodekey
as well as node_info.json
.
kgen
takes the associated IP and Port number as follows.
$ kgen --ip "123.456.789.012" --port 32323 --file$ lsnodekey node_info.json
The nodekey
is a 64-byte hexadecimal string which is a private key used in the node internally. This private key must be present at the Kaia data directory and be careful not to lose it.
$ cat nodekeyf08f2118c455a6c9c9b5e035d3571e570a719ea61771e268546e796a264acc2b$ mv nodekey ~/kcnd_home
The created file node_info.json
includes the following contents.
Key Name | Description | Example |
---|---|---|
NodeAddress | an address of the associated node | 0xc8a23d67f2471066fa1b07270651fea7e5c0cf78 |
NodeKey | the node key (a.k.a private key) | aaa7248dfdf19418ae9121a0f39db39c5c27a3e404ea7c1b8e020ca8dbe7e71a |
NodeURI | node URI | kni://4f2f47f3bf35a2c576d3345e6e9c49b147d510c05832d2458709f63c3c90c76ead205975d944ed65e77dd4c6f63ebe1ef21d60da95952bc1e200e7487f4d9e1b@123.456.789.012:32323?discport=0 |
node_info.json
contains the node information in a JSON format as follows.
$ cat node_info.json{ "NodeAddress": "0xc8a23d67f2471066fa1b07270651fea7e5c0cf78", "NodeKey": "aaa7248dfdf19418ae9121a0f39db39c5c27a3e404ea7c1b8e020ca8dbe7e71a", "NodeURI": "kni://4f2f47f3bf35a2c576d3345e6e9c49b147d510c05832d2458709f63c3c90c76ead205975d944ed65e77dd4c6f63ebe1ef21d60da95952bc1e200e7487f4d9e1b@123.456.789.012:32323?discport=0"}
Node URI Enrollment
The created node URI should be enrolled to participate in the Core Cell Network (CCN). The process of the enrollment is as follows.
- Create a node URI using
kgen
(node_info.json
) which contains the associated IP and Port number. - Send the information to the official Kaia email address (
bootstrap@klaytn.com
for Mainnet orbaobab@klaytn.com
for Kairos).
The enrolled information should be sent to the official Kaia email address. The format is as follows.
