Chain Parameters

XYZ Chain modules are configured with specific parameters that govern the blockchain’s behavior. These parameters can be modified through governance proposals.

Staking Parameters

Controls validator operations and delegation.

Parameter	Value	Description
`unbonding_time`	14 days (1,209,600s)	Time to unbond staked tokens
`max_validators`	100	Maximum active validators
`max_entries`	7	Max unbonding/redelegation entries
`historical_entries`	10000	Historical entries for IBC
`bond_denom`	`uxyz`	Token used for staking
`min_commission_rate`	5% (0.05)	Minimum validator commission

Query Staking Params

xyzd query staking params --node tcp://localhost:26657

Example Output

unbonding_time: 1209600s
max_validators: 100
max_entries: 7
historical_entries: 10000
bond_denom: uxyz
min_commission_rate: "0.050000000000000000"

Slashing Parameters

Defines penalties for validator misbehavior.

Parameter	Value	Description
`signed_blocks_window`	10,000	Blocks to track signing
`min_signed_per_window`	5% (0.05)	Minimum signing required
`downtime_jail_duration`	10 minutes (600s)	Jail time for downtime
`slash_fraction_double_sign`	5% (0.05)	Slash for double signing
`slash_fraction_downtime`	1% (0.01)	Slash for downtime

Slashing Scenarios

Double Signing

Signing two different blocks at the same height results in:

5% slash of staked tokens
Permanent tombstone (can’t rejoin validator set)

Downtime

Missing more than 95% of blocks in a window results in:

1% slash of staked tokens
10 minute jail (can unjail after)

Query Slashing Params

xyzd query slashing params --node tcp://localhost:26657

Governance Parameters

Controls proposal and voting mechanics.

Parameter	Value	Description
`min_deposit`	10 XYZ (10,000,000 uxyz)	Minimum deposit for proposal
`max_deposit_period`	2 days (172,800s)	Time to reach min deposit
`voting_period`	2 days (172,800s)	Duration of voting
`quorum`	33.4% (0.334)	Minimum participation
`threshold`	50% (0.5)	Yes votes needed to pass
`veto_threshold`	33.4% (0.334)	NoWithVeto to reject

Query Governance Params

Distribution Parameters

Controls reward distribution.

Parameter	Value	Description
`community_tax`	2% (0.02)	Tax sent to community pool
`withdraw_addr_enabled`	true	Allow custom withdraw address

Mint Parameters (ZERO INFLATION)

Critical: XYZ Chain has zero inflation. The mint module is effectively disabled.

Parameter	Value	Description
`mint_denom`	`uxyz`	Denomination to mint
`inflation`	0	Current inflation rate
`inflation_min`	0	Minimum inflation
`inflation_max`	0	Maximum inflation
`inflation_rate_change`	0	Inflation change rate
`goal_bonded`	0	Target bonded ratio
`blocks_per_year`	6,311,520	Expected blocks/year

Verify Zero Inflation

xyzd query mint inflation --node tcp://localhost:26657

Expected output:

0.000000000000000000

All mint parameters are set to zero, ensuring no new tokens are ever created. Validator rewards come entirely from transaction fees.

Crisis Parameters

Controls the invariant checking mechanism.

Parameter	Value	Description
`constant_fee`	1,000 XYZ	Fee to trigger invariant check

The crisis module allows anyone to halt the chain if a critical invariant is violated (e.g., total supply mismatch). The high fee prevents abuse.

Wasm Parameters

Controls CosmWasm smart contract operations.

Parameter	Value	Description
`code_upload_access`	Everybody	Who can upload contracts
`instantiate_default_permission`	Everybody	Who can instantiate
`max_wasm_code_size`	800 KB	Maximum contract size

Query Wasm Params

xyzd query wasm params --node tcp://localhost:26657

Example Output

code_upload_access:
  permission: Everybody
  addresses: []
instantiate_default_permission: Everybody

IBC Parameters

Inter-Blockchain Communication configuration.

Parameter	Value	Description
`allowed_clients`	All	Supported IBC clients
`max_expected_time_per_block`	30s	Block time for timeouts

Active IBC Channels

# List all channels
xyzd query ibc channel channels --node tcp://localhost:26657

# List connections
xyzd query ibc connection connections --node tcp://localhost:26657

Modifying Parameters

Parameters can be modified through governance proposals:

# Create parameter change proposal
xyzd tx gov submit-proposal param-change proposal.json \
  --from my-key \
  --chain-id xyz-testnet-1

# Example proposal.json
{
  "title": "Update Min Commission Rate",
  "description": "Increase minimum validator commission to 10%",
  "changes": [
    {
      "subspace": "staking",
      "key": "MinCommissionRate",
      "value": "0.100000000000000000"
    }
  ],
  "deposit": "10000000uxyz"
}

Parameter changes require passing a governance vote. The voting period is 2 days and requires 33.4% quorum.
