Chain Parameters

Module parameters configured on XYZ Chain

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.
