Leaving
Every 50,000 Blocks (3 days) the system will churn its nodes:
The oldest node, or
The most unreliable node
Churned nodes will be put in standby, but their bond will not automatically be returned. They will be credited any earned rewards in their last session. If they do nothing but keep their cluster online, they will be eventually churned back in.
Alternatively, a node can leave the system voluntarily, in which case they are typically churned out 6 hours later. Leaving is considered permanent, and the node-address is permanently jailed. This prevents abuse of the LEAVE system since leaving at short notice is disruptive.
It is assumed nodes that wish to LEAVE will be away for a significant period of time, so by permanently jailing their address, it forces them to completely destroy and re-build before re-entering. This also ensures they are running the latest software.
You can only unbond when your Node is on "standby", ie, just before it is selected to churn in, or after it is churned out.
If a Node Operator wants to retrieve part of their bond & rewards (such as deciding to take profits and contribute as a liquidity provider in order to maximise yield), they can simply Unbond. This keeps their Node on standby, ready to be churned back in.
To unbond from the system, simply send an UNBOND transaction to the Vault Address with at least 1 satoshi in funds. The amount and type of asset you use to send to THORChain is actually irrelevant, you are simply passing transaction intent to THORChain and proving you own your bond address.
Example, this will draw out 10k in RUNE from the bond, as long as the remaining amount is higher than the minimum bond.
UNBOND:thor1ryr5eancepklax5am8mdpkx6mr0rg4xjnjx6zz:1000000000
You can get your node address, as well as the current vault address by running make status
Only the address that originally bonded the funds can UNBOND or LEAVE. This ensures you can safely leave this system if you no longer have access to your node (but it is still running).
Leaving is considered permanent. There are two steps.
If you are active, send a LEAVE transaction to start a churn-out process. This could take several hours.
If you are standby, send a LEAVE transaction to get your bond back and be permanently jailed.
To leave the system, send the following transaction from your original bond address to the Vault Address: LEAVE:<ADDRESS> with at least 1 satoshi in funds.
Example:
LEAVE:thor1ryr5eancepklax5am8mdpkx6mr0rg4xjnjx6zz
⏱Wait a few hours, verify you are now in standby👀
LEAVE:thor1ryr5eancepklax5am8mdpkx6mr0rg4xjnjx6zz
⏱Wait a few minutes, verify you have received your bond back 👀
🔥 Commence destroying your node 🔥
If your node is both offline and inaccessible, then it will be unable to return any assets in its yggdrasil vaults and it will be slashed 1.5x the value of those assets.
Example: If your node has a $500k bond (in RUNE), but has $100k in assets in its vaults it can't return, it will lose $150k in RUNE from its bond. The Node will get back $350k in its bond.
You should complete this checklist before you do the next step:
Have you sent a final LEAVE transaction and have you received your BOND back - ie 1,000,000 RUNE, and can your account for any slash points or rewards?
If yes, then proceed:
To destroy and remove previously created resources, you can run the command below.
Destroying your cluster will completely destroy your node, including purging all keys on it.
DO NOT DO THIS UNTIL YOUR NODE HAS CHURNED OUT AND YOU HAVE VERIFIED YOUR BOND IS COMPLETELY RETURNED
IF YOU DESTROY A NODE PREMATURELY, YOU MAY LOSE A SIGNIFICANT AMOUNT OF FUNDS
First, destroy the node and tools, this will delete your node then your tooling 1-by-1. Do this from the node-launcher repo:
make destroy destroy-tools
Then destroy the cluster from the cluster-launcher repo:
You will be asked to enter your cluster name and region (the same as what you put in when you first deployed).
make destroy-aws
You will be asked to enter your cluster name and region, as well as your Personal Token (the same as what you put in when you first deployed).
make destroy-do
You will be asked to confirm:
DO NOT DESTROY YOUR NODE UNTIL YOU HAVE CHURNED OUT AND HAVE RECEIVED YOUR FULL BOND BACK IN YOUR CUSTODY
IF YOU DESTROY YOUR NODE WITH FUNDS LOCKED UP - YOU WILL LOSE A SIGNIFICANT QUANTITY OF FUNDS
