# Constants and Mimir ## Overview The network launched with a set number of constants, which has not changed. Constants can be overridden via Mimir and nodes have the ability to [**vote on**](https://docs.mayaprotocol.com/node-docs/mayanodes/overview#node-voting) and change Mimir values. Mimir setting can be created and changed without a corresponding Constant. **Values** * Constant Values:[**https://midgard.mayachain.info/v2/mayachain/constants**](https://midgard.mayachain.info/v2/mayachain/constants) * Mimir Values: [**https://midgard.mayachain.info/v2/mayachain/mimir**](https://midgard.mayachain.info/v2/mayachain/mimir) **Key**: * No Star or Hash - Constant only, no Mimir override. * Star (\*) indicates a Mimir override of a Constant * Hash (#) indicates Mimir with no Constant. ## Outbound Transactions `OutboundTransactionFee`: Amount of cacao to withhold on all outbound transactions (1e8 notation) ### Scheduled Outbound `MaxTxOutOffset`: Max number of blocks a scheduled outbound transaction can be delayed `MinTxOutVolumeThreshold`: Quantity of outbound value (in 1e8 cacao) in a block before its considered "full" and additional value is pushed into the next block `TxOutDelayMax`: Maximum number of blocks a scheduled transaction can be delayed `TxOutDelayRate`: Rate of which scheduled transactions are delayed ## **Swapping** `HaltTrading`: Pause all trading `HaltTrading`: Pause trading on a specific chain `MaxSwapsPerBlock`: Artificial limit on the number of swaps that a single block with process `MinSwapsPerBlock`: Process all swaps if the queue is equal to or smaller than this number ### **Synths** `MaxSynthPerAssetDepth`: The amount of synths allowed per pool relative to the pool depth `BurnSynths`#: Enable/Disable burning synths `MintSynths`\*: Enable/Disable minting synths `VirtualMultSynths`: The amount of increase the pool depths for calculating swap fees of synths ## **LP Management** `PauseLP`\*: Pauses the ability for LPs to add/remove liquidity `PauseLP`\*: Pauses the ability for LPs to add/remove liquidity, per chain `MaximumLiquidityCacao`\*: Max cacao capped on the pools known as the ‘soft cap’ `LiquidityLockUpBlocks`: The number of blocks LP can withdraw after their liquidity ### **Impermanent Loss Protection** `FullImpLossProtectionBlocks`\*: Number of blocks before an LP gets full imp loss protection `ILP-DISABLED-`\*: Enable/Disable imp loss protection per asset ## **Chain Management** `HaltChainGlobal`\*: Pause observations on all chains (chain clients) `HaltTrading`: Stops swaps and additions, if done, will result in refunds. Observations still occur. `HaltChain`\*: Pause a specific blockchain `HaltChain`\*: Pause a specific blockchain `NodePauseChainGlobal`: Individual node controlled means to pause all chains `NodePauseChainBlocks`: Number of block a node operator can pause/resume the chains for `BlocksPerYear`: Blocks in a year `MaxUTXOsToSpend`\*: Max UTXOs to be spent in one block `MinimumNodesForBFT`: Minimum node count to keep the network running. Below this, Ragnarök is performed. ### **Fee Management** `NativeTransactionFee`: Cacao fee on all on chain txs `TNSRegisterFee`: Registration fee for new MAYAName, in cacao `TNSFeeOnSale`: fee for TNS sale in basis points `TNSFeePerBlock`: per block cost for TNS, in cacao ### **Solvency Checker** `StopSolvencyCheck`#: Enable/Disable Solvency Checker `StopSolvencyCheck`#: Enable/Disable Solvency Checker, per chain `PermittedSolvencyGap`: The amount of funds permitted to be "insolvent". This gives the network a little bit of "wiggle room" for margin of error ## **Node Management** `MaximumBondInCacao`: Sets an upper cap on how much a node can bond `MinimumBondInCacao`\*: Sets a lower bound on bond for a node to be considered to be churned in `ValidatorMaxRewardRatio`\*: the ratio to MinimumBondInCacao at which validators stop receiving rewards proportional to their bond ### **Yggdrasil Management** `YggFundLimit`: Funding limit for yggdrasil vaults (percentage) `YggFundRetry`\*: Number of blocks to wait before attempting to fund a yggdrasil again `StopFundYggdrasil`#: Enable/Disable yggdrasil funding `ObservationDelayFlexibility`\*: Number of blocks of flexibility for a validator to get their slash points taken off for making an observation `PoolDepthForYggFundingMin`\*: the minimum pool depth in CACAO required for ygg funding `MinimumNodesForYggdrasil`: No yggdrasil pools if MAYANode have less than 6 active nodes ### **Slashing Management** `LackOfObservationPenalty`: Add two slash points for each block where a node does not observe `SigningTransactionPeriod`: How many blocks before a request to sign a tx by yggdrasil pool, is counted as delinquent. `DoubleSignMaxAge`: Number of blocks to limit double signing a block `FailKeygenSlashPoints`: Slash for 720 blocks, which equals 1 hour `FailKeysignSlashPoints`: Slash for 2 blocks `ObserveSlashPoints`: the number of slashpoints for making an observation (redeems later if observation reaches consensus `ObservationDelayFlexibility`: number of blocks of flexibility for a validator to get their slash points taken off for making an observation `JailTimeKeygen`: blocks a node account is jailed for failing to keygen. DO NOT drop below TSS timeout `JailTimeKeysign`: blocks a node account is jailed for failing to keysign. DO NOT drop below TSS timeout ### **Churning** `AsgardSize`: Defines the number of members to an Asgard vault `MinSlashPointsForBadValidator`: Min quantity of slash points needed to be considered "bad" and be marked for churn out `BondLockupPeriod`: Lockout period that a node must wait before being allowed to unbond `ChurnInterval`\*: Number of blocks between each churn `HaltChurning`: Pause churning `DesiredValidatorSet`: Max number of validators `FundMigrationInterval`\*: Number of blocks between attempts to migrate funds between asgard vaults during a migration `NumberOfNewNodesPerChurn`#: Number of targeted additional nodes added to the validator set each churn `BadValidatorRedline`\*: Redline multiplier to find a multitude of bad actors `BadValidatorRate`: Rate to mark a validator to be rotated out for bad behavior `OldValidatorRate`: Rate to mark a validator to be rotated out for age `LowBondValidatorRate`: Rate to mark a validator to be rotated out for low bond ## **Economics** `EmissionCurve`\*: How quickly cacao is emitted from the reserve in block rewards `IncentiveCurve`\*: The split between nodes and LPs while the balance is optimal `MaxAvailablePools`: Maximum number of pools allowed on the network. Gas pools (native pools) are excluded from this. `MinCacaoPoolDepth`\*: Minimum number of cacao to be considered to become active `PoolCycle`\*: Number of blocks the network will churn the pools (add/remove new available pools) `StagedPoolCost`: Number of cacao (1e8 notation) that a stage pool is deducted on each pool cycle.
