Testnet 3000 Genesis Parameters

This genesis time puts nighttime in the pacific (early-ish for San Francisco and late-ish for Korea: Timezone chart).

"genesis_time": "2019-10-03T14:00:00Z",

},

Distribution

Main params are the same as cosmos hub 3 and 2 except community pool, and withdraw address. withdraw_addr_enabled should be set when txs are enabled Disable community pool by setting tax to 0.

"distribution": {
    "fee_pool": {

Mint

Mint has same parameters as hubs 1, 2, and 3 except

• block_per_year calculated from test 2000 block time (6.24s per block, 365.25 days/year)
• inflation which is just the initial value for inflation, set to the min, as hub 1 did ref: cosmos/cosmos-sdk#2846 annual_provisions is fine to start at zero, the setting here is just the initial value. It gets computed each block from the inflation percentage and the total supply.

    "mint": {
        "minter": {
            "inflation": "0.070000000000000000",
            "annual_provisions": "0.000000000000000000"

        }
    },

Auth

Same params as hub 3, 2, and 1. But now accounts are stored under auth rather than genaccounts

"auth": {
    "params": {
        "max_memo_characters": "512",
        "tx_sig_limit": "7",
        "tx_size_cost_per_byte": "10",

    }
    "accounts": [...]
},

Params

params has no genesis state

"params": null

Gov

Same params as the cosmos hubs except voting_period is capped by the unbonding time, and deposit_period is a week to better match testnet timelines. Note: voting period must be less than unbonding period otherwise people could vote, redelegate, then vote again.

"gov": {
    "starting_proposal_id": "1",
    "deposits": null,
    "votes": null,
    "proposals": null,
    "deposit_params": {
        "min_deposit": [
            {

                "amount": "512000000"
            }
            ],
        "max_deposit_period": "604800000000000" // 1 week
    },
    "voting_params": {
        "voting_period": "259200000000000" // 3 days, has to be ≤ unbonding time
    },
    "tally_params": {

    }
},

Staking

Params same as hub 3, 2, and 1 except for unbonding time which is 3 days. (gaia testnet 13k used 3 days)

"staking": {
    "params": {
        "unbonding_time": "259200000000000", // 3 days
        "max_validators": 100,
        "max_entries": 7,

    },
    "last_total_power": "0",
    "last_validator_powers": null,
    "validators": null,
    "delegations": null,
    "unbonding_delegations": null,
    "redelegations": null,
    "exported": false
},

Slashing

Currently all the same cosmos hub 3, 2, and 1 except max_evidence_age which is set to the staking unbonding time

"slashing": {
    "params": {
        "max_evidence_age": "259200000000000", // 3 days, must be same as unbonding period
        "signed_blocks_window": "10000", // 17.33hrs hours @ 6.24s block time (block time of testnet 2000)
        "min_signed_per_window": "0.050000000000000000", // can be down for up to 16.46hrs without slashing
        "downtime_jail_duration": "600000000000", // 10min
        "slash_fraction_double_sign": "0.050000000000000000",
        "slash_fraction_downtime": "0.000100000000000000"
    },
    "signing_infos": {},
    "missed_blocks": {}
},

Supply

Note: neither add-genesis-account or collect-gentx modifies the supply. If it's empty here, then it's set when the chain starts based on the accounts.

"supply": {
    "supply": {
        "total": []
    }
}
