Disable staking power change for protecting the network
This release contains a wasmer version bump from v2.0.0 to v2.2.1. The wasm caches of these two versions are not compatible, thus rebuilding is required. To avoid possible sync delays due to the runtime rebuilding overhead, it is highly recommended that node operators rebuild their wasm cache with the cosmwasm-cache-rebuilder before replacing terrad runtime to v0.5.18.
Node upgrade instructions
- Rebuild your wasm cache using the cosmwasm-cache-rebuilder. This rebuilder can be run simultaneously without killing a running terrad process.
- You can ignore the file already open error. If other errors occur (no disk space, etc), it is safe to run the rebuilder multiple times.
- When the rebuilder is finished, update terrad to v0.5.18 and restart.
- The rebuilder creates a
$TERRA_HOME/data/wasm/cache/modules/v3-wasmer1directory. The$TERRA_HOME/data/wasm/cache/modules/v1can be deleted after updating terrad to v0.5.18.
Additional notes
- 🎉 Wasmer v2.2 supports the much anticipated Apple M1 processor! (See: https://wasmer.io/posts/wasmer-2.2) This means nodes can be run on any arm64 system, such as Apple Silicon machines and AWS Graviton2 Arm64.

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.
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-recentpruning-keep-everypruning-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.

A validator get slashed SlashFraction% if the one perform any of the following violations in SlashWindow - minValidPerWindow voteperiods over a window of SlashWindow voteperiods:
- 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.
- A submitted vote is more than max(
RewardBand, standard deviation) from the elected median - Oracle voters who submit abstain vote with other invalid votes will also get slashed.

- 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.
- Use
/bank/accounts/{address}/transferswithout fees.terracliwill compute tax amount and fill fees field containing both gas & tax fee. - Use
/txs/estimate_feeto estimate fees of StdTX, and replace StdTx.Fee.Amount to estimated fee - Compute tax with
/treasury/tax_rate&/treasury/tax_capadd computed tax with original gas fee
- Use
#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 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.

#150 Market Swap protections
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.
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.
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).
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.
