# 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

```bash theme={null}
xyzd query staking params --node tcp://localhost:26657
```

<Accordion title="Example Output">
  ```yaml theme={null}
  unbonding_time: 1209600s
  max_validators: 100
  max_entries: 7
  historical_entries: 10000
  bond_denom: uxyz
  min_commission_rate: "0.050000000000000000"
  ```
</Accordion>

## 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

<CardGroup cols={2}>
  <Card title="Double Signing" icon="clone">
    Signing two different blocks at the same height results in:

    * **5% slash** of staked tokens
    * **Permanent tombstone** (can't rejoin validator set)
  </Card>

  <Card title="Downtime" icon="power-off">
    Missing more than 95% of blocks in a window results in:

    * **1% slash** of staked tokens
    * **10 minute jail** (can unjail after)
  </Card>
</CardGroup>

### Query Slashing Params

```bash theme={null}
xyzd query slashing params --node tcp://localhost:26657
```

## Governance Parameters

| `veto_threshold`     | 33.4% (0.334)            | NoWithVeto to reject         |

## 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)

<Warning>
  **Critical:** XYZ Chain has zero inflation. The mint module is effectively disabled.
</Warning>

| 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

```bash theme={null}
xyzd query mint inflation --node tcp://localhost:26657
```

Expected output:

```
0.000000000000000000
```

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

## 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

```bash theme={null}
xyzd query wasm params --node tcp://localhost:26657
```

<Accordion title="Example Output">
  ```yaml theme={null}
  code_upload_access:
    permission: Everybody
    addresses: []
  instantiate_default_permission: Everybody
  ```
</Accordion>

## 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

```bash theme={null}
# 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:

```bash theme={null}
# 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"
}
```

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