Genesis Parameters

DESMOS will be running with the following parameters at genesis. Most of the parameters can be updated by using a ParameterChangeProposal and the x/gov module. Below we list only the changes to the parameters from the Cosmos SDK modules. All the other parameters values are going to be the default ones.

Base

  • "genesis_time": "2021-08-31T15:00:00Z". 31 Aug 2021 3pm UTC
  • "chain_id": "desmos-1". The Chain ID of the DESMOS mainnet will be desmos-1.

Consensus

  • "max_gas": "100000000". Maximum gas per block is set to 100,000,000. Considering the default 200,000 gas per transaction, this means 500 transactions should be included inside each block.
  • "max_age_duration": "1209600000000000". 2 weeks for double sign evidence.
  • "max_age_num_blocks": "204670". This is calculated by max_age_duration / 5.91 which is the average block time on morpheus-apollo-2 testnet.

Crisis

  • "amount": "13333000000". We will need 13333 DSM to halt the chain if anything goes wrong.

Distribution

  • "community_tax": "0.200000000000000000". The tax on inflation and fees for community pool will be 20%.

Governance

  • "min_deposit": 500000000udesmos. The minimum deposit to make a proposal turn into voting period will be 500 DSM.
  • "max_deposit_period": "259200s". The maxmium deposit period for a proposal will be 259,200 seconds which is 3 days.
  • "voting_period": "604800s". The voting period of a proposal will be 604,800 seconds which is 7 days.

Mint

  • "mint_denom": "udsm". The mint denom will be udsm. This is the smallest unit of the staking token DSM.
  • "inflation_rate_change": "1.000000000000000000". Inflation change rate is set to 1 to have the optimum speed to make the inflation rate change to the target inflation.
  • "inflation_max": "0.000000000000000000" and "inflation_min": "0.000000000000000000". Both parameters are set to 0 at genesis to avoid an imbalanced sudden change of token distribution at launch. These values will be changed by a ParameterChangePropoal right after launch. According to the parameters inside the Governance module, the earliest time for the parameter change to happen will be 7 days after the genesis time. This period of zero inflation will give enough time for token holders to stake until inflation is turned on. The inflation_max will be set to 0.8 and inflation_min will be set to 0.4 as written in the whitepaper.
  • "goal_bonded": "0.9". We see staking ratio can reach over 82% on other networks. We are setting a higher goal_bonded to attract token holders to stake and incentivize early stakers.
  • "blocks_per_year": "5339695". Based on 5.91 seconds of average block time on morpheus-apollo-2 testnet.

Slashing

  • "signed_blocks_window": "150000". This is around 24 hours based on 5.91 seconds block time.
  • "min_signed_per_window": "0.050000000000000000. Validators will be kept on active set if they sign 5% of blocks in every signed_blocks_window.
  • "downtime_jail_duration": "1800s". Down time for uptime jail is 30 minutes.
  • "slash_fraction_double_sign": "0.050000000000000000". Validators and their delegators will encounter 5% slashing on their staked tokens if the validators double sign.
  • "slash_fraction_downtime": "0.000100000000000000". Validators and their delegators will encounter 0.01% slashing on their staked tokens if the validators cannot meet the uptime requirement.

Staking

  • "unbonding_time": "1209600s". Unbonding period on DESMOS is set to 1209600 seconds which is 14 days.
  • "bond_denom": "udsm". The bond denom is udsm. This is the smallest unit of the DSM.
