Joining the Network
How to join LastNetwork as a Node.
Joining LastNetwork
Now that you have a LastNode deployed in your Kubernetes cluster, you need to start operating your node to join the network.
There are a couple of steps to follow to do so.
1. Check your current node status
The first step would be to make sure your deployment was successful and your node is running correctly. _**_To check the current status of your node, you can run the command status from the node-launcher
repository on your terminal:
make status
You will get an output along those lines, the example below is for a testnet node:
ADDRESS last13hh6qyj0xgw0gv7qpay8thfucxw8hqkved9vr2
IP
VERSION 0.0.0
STATUS Unknown
BOND 0.00
REWARDS 0.00
SLASH 0
PREFLIGHT { "status": "Standby", "reason": "node account has invalid registered IP address", "code": 1 }

CHAIN SYNC BLOCKS
LAST 55.250% 37,097/67,144
BTC 2.399% 227,986/678,340
ETH 7.764% 947,182/12,199,994
Your node is running but as you can see in the `Preflight` section, your node is not yet ready to be churned in and currently is in standby status, since your node has no IP address setup yet.
But to be able to set up the node IP address, you first need to get it registered in the chain by sending your BOND.
Before sending the BOND, verify that your LastNode is fully synced with connected chains. Connected chains such as Ethereum & Bitcoin may take a day to sync. If your node is fully bonded and is selected to churn in to LastNetwork as ACTIVE without fully syncing all connected chains, you will immediately get slashed for missing observations, and lose money. It is normal to see Ethereum sit on 99.999% for many hours - be patient.
2 - Send a small BOND (recommend 100-1000)
-
You will do a “Deposit” transaction using native LastNetwork CUBE. This is an internal MsgDeposit transaction (different from a MsgSend to another wallet). There is no destination address — use an appropriate wallet such as LAST_ELECTRON. The Bond is locked in a module controlled by the state machine.
-
Deposit your BOND using the memo
BOND:<LastNode-address>
(or use an appropriate GUI that does this memo for you). Start small, the bond will be picked up.
Some make
commands during setup require CUBE (0.02 to 1.0) to execute into the state machine to prevent DDoS. If your bond is too small (e.g. 1 CUBE) you may run out and not be able to complete the setup until adding more.
Give the network 3-5 seconds to pick up your bond. To verify it has received your bond, run the following:
curl https://orb.last.net/lastnetwork/node/<node-address>
If you run make status
again, you should see this:
ADDRESS last13hh6qyj0xgw0gv7qpay8thfucxw8hqkved9vr2
IP
VERSION 0.0.0
STATUS Whitelisted
BOND 1000.00
REWARDS 0.00

LTC 0.012% 6,526/1,818,000
BCH 2.293% 197,340/682,404
As you can see, it is in standby but does not have an IP registered yet. This is needed for peer discovery.
3 - Setup Node IP Address
You must tell LastNetwork your IP-Address for its address book and seed-service to run properly:
make set-ip-address
If you run the status command again, you should now see a different message for the Preflight section saying you need to set your node keys.
Once your IP address has been registered for discovery, you can use your own host for queries.
4 - Setup Node keys
Tell LastNetwork about your public keys for signing sessions:
make set-node-keys
If you run the make status
command again, you should now see that your node is in status “ready” and is now ready to be churned in the next rotation.
5 - Set Version
Make sure your node broadcasts its latest version, else you won’t churn in since LastNetwork enforces a version requirement. This version will appear in your make status
. If you are on 0.0.0
then you haven’t set your version:
make set-version
6 - Send Final Bond
If you followed steps 1-5 above, your preflight will be saying:
PREFLIGHT { "status": "Standby", "reason": "node account does not have minimum bond requirement: 100000000000/30000000000000, "code": 1 }
To address this, send the remaining bond, that is higher than the minimum bond. You can find that quantity on https://LastNode.LastNetwork.info/LastNetwork/constants and look for MinimumBondInCUBE
. During Chaosnet some values may be override with MIMIR. If you finally run make status
you should see this, with keyword “Ready”:
ADDRESS last13hh6qyj0xgw0gv7qpay8thfucxw8hqkved9vr2

Bonding The Right Amount
Although your node is ready to be churned in, it doesn’t mean it will be the next one to be selected since someone else could have posted a higher bond than you. To maximise chances of a quick entry, monitor Midgard to see what everyone else is bonding and try to outbid them. Keep an eye on maximumStandbyBond
and make sure you are bonding higher than that amount.
curl http://52.221.153.64:8080/v2/network | json_pp
resp:
"bondMetrics" : {
"minimumActiveBond" : "10001000000000",
"medianStandbyBond" : "1010000000000",
"medianActiveBond" : "15001000000000",
"averageStandbyBond" : "1010000000000",
"maximumActiveBond" : "15001000000000",
"averageActiveBond" : "12006800000000",
"maximumStandbyBond" : "1010000000000",
"totalStandbyBond" : "1010000000000",
"totalActiveBond" : "60034000000000",
"minimumStandbyBond" : "1010000000000"
}
The endpoint will show data on average, median, total, minimum and maximum bond amounts. For fastest entry, bond higher than the current maximum.
CUBE is always displayed in 1e8 format, 100000000 = 1 CUBE
Bonding More
At any time during standby, you can bond more by making an additional BOND transaction with memo:
BOND:<LastNode-address>
Only the original wallet that did the first BOND will be able to LEAVE/UNBOND. You can top up BOND using a different wallet but make sure you keep the private key to the original BOND wallet secure and accessible.
You can also remove some of your bond whilst you are on standby, using the UNBOND memo.
Node Operator Fee
- Setting the Node Operator fee
10000
causes all rewards to be paid back each churn. - Setting the Node Operator fee to
5000
causes 50% of rewards to be paid back to the Node Operator address and 50% to be accrued back to the bond.
To set a Node Operator fee, send a deposit transaction with the following memo:
BOND:<node address>:<bond wallet address>:<operator fee in basis pts>
