Proof of Liquidity FAQ
Initially, MGX-KSM will be eligible for PoL. After a short transitionary period, more pairs will be added.
Yes, you can delegate your stake to multiple collators.
As in Kusama, 7 days are required to perform unbonding on Proof-of-Liquidity.
As of 2023-03-28, the maximum is 12 delegators per collator. We expect this number to rise within a few runtime upgrades.
Everyone can run a node. Selection into the active set is permissionless and dependent on the most liquidity put at stake.
As of July 2023, a maximum of 25 nodes can be in the active set. Our mid-term ambition is to have 100, but this is subject to technical challenges we need to overcome.
The nodes with the highest liquidity will get selected for collation.
No. Each node selects a single type of liquidity when joining the candidate pool. But node operators are free to set up additional nodes if they want to cover other pairs. We are working to make multiple pairs possible in the future.
We don’t know the practical limit yet.
In general, it is considered that parachain collators only produce valid blocks for relay chain Validators to validate against them. The idea is that Validators provide security.
In the case of Mangata, Collators protect against an additional attack vector that Validators do not: front-running. This is an economic attack vector that is generally not considered central to running a blockchain. But in practice, front-running and MEV increasingly degrade the quality of a network.

To protect against this network, we developed Themis Protocol, which prevents front-running by introducing a novel method to split block production between nodes. This introduces the need for Collators also to build an actual network.
You can acquire liquidity by adding it to the DEX.
The minimum bond is 3m MGX in value.
How much stake do I need to get into the active set?
To find out how much your LP is worth, check out: How to check the value of an LP token. For example, if there is a total of 1T LP tokens and the MGX side of the liquidity pool is 1M MGX, then the total pool is worth 2M MGX, and 1 LP token is 2M / 1T = 0.002 MGX.
Node operators get 20% of collation rewards. Collation rewards are 240m MGX per year. That’s 20m MGX per month, split up amongst all collators in the active set.
The rewards of a node are dependent on the successful collation of blocks (era points). The rewards of individual delegators are dependent on their share of the liquidity within the node.
At the end of each session, about every 4 hours.
Only MGX-based liquidity is allowed for Proof-of-Liquidity. The amount of MGX in the LP can thus be compared and determines the relative value of the pools.
We have identified slashable behavior, but have not yet identified it as slashable. We want to gather more real-world data before making further design decisions.
We consider setting up a similar program.
This error most likely happens because you are not in the tab with the UI Workaround. Please follow the instructions and links in the appropriate tabs.
- Geographical Decentralization vs. Missed Blocks vs. Missing Transactions: How does geographical decentralization affect the network, when blocks are missed that are needed to decrypt transactions.
- What are the actual hardware requirements?
- is scheduleBondMore AND executeBondMore really needed or could this be compressed into a single extrinsic
- Assign a few collators to run archive nodes
- Figure out correct firewall setup
- Investigating: Only a single peer?
- 1.Got this warning during compiling. The code is compiling, so not a big deal. I think that the Cargo is type-checking the code. Probably a good idea for devs to update the code to clean up the unused imports.
