Breaking Changes

#265 Oracle refactor & Oracle slashing

Slashing

A validator get slashed SlashFraction% if the one perform any of the following violations in SlashWindow - minValidPerWindow voteperiods over a window of SlashWindow voteperiods:

1. A vote is missing for any of the denom in the whitelist. Oracle voters looking to abstain must still submit a "vote of no confidence", which has 0 for the luna ExchangeRate field of the prevote.
2. A submitted vote is more than max(RewardBand, standard deviation) from the elected median
3. Oracle voters who submit abstain vote with other invalid votes will also get slashed.

Codec Changes

• oracle/MsgDelegateFeederPermission => oracle/MsgDelegateFeedConsent

New End Points

• /oracle/voters/{%s}/miss return the # of vote periods missed in this oracle slash window.

Path Changes

• /oracle/denoms/{denom}/price => /oracle/denoms/{denom}/exchange_rate

Request Body Changes

• POST /oracle/denoms/{denom}/prevotes
• POST /oracle/denoms/{denom}/votes

Price sdk.Dec `json:"price"`

has been changed to

ExchangeRate sdk.Dec `json:"exchange_rate"`

#256 Oracle endpoints improvement

New EndPoints

/oracle/voters/{validator}/votes
/oracle/voters/{validator}/prevotes
/oracle/denoms/prices

#250 Oracle whitelist & Reward distribution update

• Create a whitelist param that stores an array of denoms that are whitelisted by the protocol.
• Edit the oracle Reward Pool of a VotePeriod = oracle module account / (n vote periods).
• Oracle module account is whitelisted in the bank module such that users can donate funds to the oracle module account

#234 Adopt gov module

distribution module already contains community-pool-spend proposal suitable for budget so budget module is removed. There are two custom governance proposals from treasury module; tax-rate-update & reward-weight-update proposals.

#233 Swap constant product

As proposed here, apply constant product to swap feature.

Compute Pools

// Both LUNA and TERRA pools are using SDR units.
cp = basePool*basePool
terraPool = (basePool + terraDelta)
lunaPool = cp/terraPool

LUNA to TERRA swap

// offerAmt must be SDR units
newLunaPool = lunaPool + offerAmt
newTerraPool = cp / newLunaPool
returnAmt = newTerraPool - terraPool

// Swap return SDR Amt to TERRA
returnLunaAmt = market.swap(returnAmt, "LUNA")

TERRA to LUNA swap

// offerAmt must be SDR units
newTerraPool = terraPool + offerAmt
newLunaPool = cp / newTerraPool
returnAmt = newLunaPool - lunaPool

// Swap return SDR Amt to proper TERRA
returnTerraAmt = market.swap(returnAmt, "TERRA")

TERRA to TERRA swap

Apply only fixed tobin-tax without computing and changing pools

New EndPoints

#231 Bump SDK to v0.37.x

REST end points, which are changed

All REST responses now wrap the original resource/result. The response
will contain two fields: height and result.

/market/params => /market/parameters
/oracle/params => /oracle/parameters
/treasury/tax-rate => /treasury/tax_rate
/treasury/tax-rate/{epoch} => /treasury/tax_rate/{epoch}
/treasury/tax-cap => /treasury/tax_cap
/treasury/tax-cap/{denom} => /treasury/tax_cap/{denom}
/treasury/reward-weight => /treasury/reward_weight
/treasury/reward-weight/{epoch} => /treasury/reward_weight/{epoch}
/treasury/tax-proceeds => /treasury/tax_proceeds
/treasury/tax-proceeds/{epoch} => /treasury/tax_proceeds/{epoch}
/treasury/seigniorage-proceeds => /treasury/seigniorage_proceeds
/treasury/seigniorage-proceeds/{epoch} => /treasury/seigniorage_proceeds/{epoch}
/treasury/current-epoch => /treasury/current_epoch
/treasury/params => /treasury/parameters

REST end points, which response object key is removed

/oracle/denoms/{denom}/price
/oracle/denoms/{denom}/prevotes/{voter}
/oracle/denoms/{denom}/prevotes

New REST endpoints

/supply/total
/supply/total/{denomination}
/market/last_day_issuance
/oracle/voters/{%s}/voting_info
/oracle/voting_infos
/treasury/historical_issuance/{epoch}

Codec changes

auth/Account => core/Account
auth/StdTx => core/StdTx
pay/MsgSend => bank/MsgSend
pay/MsgMultiSend => bank/MsgMultiSend

Other Changes

• GradedVestingAccount is fully removed
• LazyGradedVestingAccount's vesting_lazy_schedules is changed to vesting_schedules
• Improve the UX of fee and tax. The sender have to specify fees containing tax amount with following methods.
  1. Use /bank/accounts/{address}/transfers without fees. terracli will compute tax amount and fill fees field containing both gas & tax fee.
  2. Use /txs/estimate_fee to estimate fees of StdTX, and replace StdTx.Fee.Amount to estimated fee
  3. Compute tax with /treasury/tax_rate & /treasury/tax_cap add computed tax with original gas fee
