Breaking Changes

Keys Migration

Any existing keys that were managed via Keybase in prior versions must be migrated. To migrate keys, execute the following:

$ terracli keys migrate [--home] [--keyring-backend]

The above command will provide a prompt for each existing key and ask if you wish for it to be skipped or not. If the key is not to be skipped, you must provide the correct passphrase for it to be migrated successfully.

Pruning Configuration

The operator can now set the pruning options by passing a pruning configuration via command line option or app.toml. The pruning flag supports the following options: default, everything, nothing, custom - see the PR for further details. If the operator chooses custom, they may want to provide either of the granular pruning values:

  • pruning-keep-recent
  • pruning-keep-every
  • pruning-interval

The former two options dictate how many recent versions are kept on disk and the offset of what versions are kept after that respectively, and the latter defines the height interval in which versions are deleted in a batch.

The operator, who wants to upgrade the node from v0.3 to v0.4, must change pruning option in app.toml to one of above options.

API Changes

  • The block_meta field has been removed from /blocks/{block_height} becasuse it was redandunt data with block_header.
  • The whitelist of/oracle/parameters response has been changed from []string to []{ name: string; tobin_tax: string; }

0.3.0

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.

New EndPoints
(GET)/gov/proposals
(GET)/gov/proposals/{proposalId}
(GET)/gov/proposals/{proposalId}/proposer
(GET)/gov/proposals/{proposalId}/deposits

#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
/market/terra_pool_delta

#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/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

0.2.4

Bug fixes

#196 peek epoch seigniorage

Change PeekEpochSeigniorage to compute seigniorage by subtracting current issuance from previous issuance

#198 Use next block for treasury tax and reward update

updateTaxPolicy and updateRewardPolicy are updating new tax-rate and reward-weight with current ctx. The ctx height is the last block of current epoch, but treasury should update next epoch's tax-rate and reward-weight at the last block of current epoch. In updateTaxPolicy and updateRewardPolicy, change ctx input of keeper setter to ctx with next epoch height.

  • #140 Client querier bug fix (distr outstanding rewards)

  • #140 Fix budget module to delete all votes when submitter withdraws the program and to use DeleteVotesForProgram to delete all votes for a program.

Improvements

#140 Msg Types

cosmos-sdk/MsgSend => pay/MsgSend
cosmos-sdk/MsgMultiSend => pay/MsgMultiSend

cosmos-sdk/MsgCreateValidator => staking/MsgCreateValidator
cosmos-sdk/MsgEditValidator => staking/MsgEditValidator
cosmos-sdk/MsgDelegate => staking/MsgDelegate
cosmos-sdk/MsgUndelegate => staking/MsgUndelegate
cosmos-sdk/MsgBeginRedelegate => staking/MsgBeginRedelegate

cosmos-sdk/MsgWithdrawDelegationReward => distribution/MsgWithdrawDelegationReward
cosmos-sdk/MsgWithdrawValidatorCommission => distribution/MsgWithdrawValidatorCommission
cosmos-sdk/MsgModifyWithdrawAddress => distribution/MsgModifyWithdrawAddress

cosmos-sdk/MsgUnjail => slashing/MsgUnjail

#140 Oracle updates prevoting/voting

MsgPriceFeed is split into MsgPricePrevote and MsgPriceVote

Period  |  P1 |  P2 |  P3 |  ...    |
Prevote |  O  |  O  |  O  |  ...    |
        |-----\-----\-----\-----    |
Vote    |     |  O  |  O  |  ...    |

In prevote stage, a validator should submit the hash of the part of real vote msg to prove the validator is not just copying other validators price vote. In vote phrase, the validator should reveal the real price by submitting MsgPriceVote with salt.

The submission order has to be kept in (vote -> prevote) order. If an prevote comes early, it will replace previous prevote so next vote, which reveals the proof for previous prevote, will be failed.

#148 Oracle voting right delegation

By using the oracle/MsgDelegateFeederPermission a validator can assign the right to vote to another account at any time. The validator account will preserve its right to vote at any time.

#140 & #148 Rest Interface Update

Change rest interface url
"/distribution/parameters" => "/distribution/params"
"/staking/parameters" => "/staking/params"
Change request body
Send request body
From:
type SendReq struct {
	BaseReq rest.BaseReq `json:"base_req"`
	Amount   sdk.Coins    `json:"coins"`
}

To:
type SendReq struct {
	BaseReq rest.BaseReq `json:"base_req"`
	Coins   sdk.Coins    `json:"coins"`
}
New rest interfaces
(GET/POST) "/oracle/denoms/{%s}/votes"
(GET/POST) "/oracle/denoms/{%s}/prevotes"
(GET/POST) "/oracle/voters/{%s}/feeder"
(GET/POST) "/market/swap"
(GET/POST) "/market/params"

#140 Add transaction logs for tax and swap amount

Send Tx

Add tax log to send transaction for recording real amount which a transaction pay. Ex) txs/B515331BF9EA9A92AD59A85D593E5A2B170E3D297C59E85DDA9FA6FF33790E9B

{
  "logs": [
    {
      "msg_index": 0,
      "success": true,
      "log": "{\"tax\":\"400uluna\"}"
    }
  ]
}
Swap Tx

Add swap_coin log to swap transaction for recording the amount of swapped coin along with offered coin

{
  "logs": [
    {
      "msg_index": 0,
      "success": true,
      "log": "{\"swap_coin\":\"400ukrw\"}"
    }
  ]
}

#150 Market Swap protections

Add bidirectional Luna supply change cap on market swaps.

A daily trading cap (luna supply change cap) protects excessive luna volatility. Capping Luna deflation prevents divesting attacks (attacker swaps large amount into terra to avoid slippage) and consensus attacks by limiting access to staking tokens. Early parameters are 2% - 10% on both sides of the trade.

Add bidirectional Luna spread fees on market swaps

To protect against short term price deviations between the open market and the on-chain oracle, we now charge a 2-10% spread on swaps that involve luna.

Change oracle reward scheme from monthly seigniorage to validators to minute distribution

Swap spreads are distributed to oracle ballot winners on the oracle VotePeriod; this vastly shortens distribution periods. Also, all stakeholders receive oracle rewards (includes delegators).

Swaps halt immediately after an illiquid oracle vote

Previously we facilitated swaps for 10 VotePeriods after the last valid oracle ballot. We now stop swaps immediately to prevent arbitrage attacks from price drift.

Parameter Changes

#150 Change MiningRewardWeight.Max from 20% to 90%. This is to reduce volatility in fees at network infancy.

Changed BlocksPerMinute from 12 to 5 to more accurately reflect Columbus block times.
