# Changelog
## 0.24.1
*August 21st, 2018*
BUG FIXES
* Gaia
- [x/slashing] Evidence tracking now uses validator address instead of validator pubkey
## 0.24.0
*August 13th, 2018*
BREAKING CHANGES
* Gaia REST API (`gaiacli advanced rest-server`)
- [x/stake] \#1880 More REST-ful endpoints (large refactor)
- [x/slashing] \#1866 `/slashing/signing_info` takes cosmosvalpub instead of cosmosvaladdr
- use time.Time instead of int64 for time. See Tendermint v0.23.0
- Signatures are no longer Amino encoded with prefixes (just encoded as raw
bytes) - see Tendermint v0.23.0
* Gaia CLI (`gaiacli`)
- [x/stake] change `--keybase-sig` to `--identity`
- [x/stake] \#1828 Force user to specify amount on create-validator command by removing default
- [x/gov] Change `--proposalID` to `--proposal-id`
- [x/stake, x/gov] \#1606 Use `--from` instead of adhoc flags like `--address-validator`
and `--proposer` to indicate the sender address.
- \#1551 Remove `--name` completely
- Genesis/key creation (`gaiad init`) now supports user-provided key passwords
* Gaia
- [x/stake] Inflation doesn't use rationals in calculation (performance boost)
- [x/stake] Persist a map from `addr->pubkey` in the state since BeginBlock
doesn't provide pubkeys.
- [x/gov] \#1781 Added tags sub-package, changed tags to use dash-case
- [x/gov] \#1688 Governance parameters are now stored in globalparams store
- [x/gov] \#1859 Slash validators who do not vote on a proposal
- [x/gov] \#1914 added TallyResult type that gets stored in Proposal after tallying is finished
* SDK
- [baseapp] Msgs are no longer run on CheckTx, removed `ctx.IsCheckTx()`
- [baseapp] NewBaseApp constructor takes sdk.TxDecoder as argument instead of wire.Codec
- [types] sdk.NewCoin takes sdk.Int, sdk.NewInt64Coin takes int64
- [x/auth] Default TxDecoder can be found in `x/auth` rather than baseapp
- [client] \#1551: Refactored `CoreContext` to `TxContext` and `QueryContext`
- Removed all tx related fields and logic (building & signing) to separate
structure `TxContext` in `x/auth/client/context`
* Tendermint
- v0.22.5 -> See [Tendermint PR](https://github.com/tendermint/tendermint/pull/1966)
- change all the cryptography imports.
- v0.23.0 -> See
[Changelog](https://github.com/tendermint/tendermint/blob/v0.23.0/CHANGELOG.md#0230)
and [SDK PR](https://github.com/cosmos/cosmos-sdk/pull/1927)
- BeginBlock no longer includes crypto.Pubkey
- use time.Time instead of int64 for time.
FEATURES
* Gaia REST API (`gaiacli advanced rest-server`)
- [x/gov] Can now query governance proposals by ProposalStatus
* Gaia CLI (`gaiacli`)
- [x/gov] added `query-proposals` command. Can filter by `depositer`, `voter`, and `status`
- [x/stake] \#2043 Added staking query cli cmds for unbonding-delegations and redelegations
* Gaia
- [networks] Added ansible scripts to upgrade seed nodes on a network
* SDK
- [x/mock/simulation] Randomized simulation framework
- Modules specify invariants and operations, preferably in an x/[module]/simulation package
- Modules can test random combinations of their own operations
- Applications can integrate operations and invariants from modules together for an integrated simulation
- Simulates Tendermint's algorithm for validator set updates
- Simulates validator signing/downtime with a Markov chain, and occaisional double-signatures
- Includes simulated operations & invariants for staking, slashing, governance, and bank modules
- [store] \#1481 Add transient store
- [baseapp] Initialize validator set on ResponseInitChain
- [baseapp] added BaseApp.Seal - ability to seal baseapp parameters once they've been set
- [cosmos-sdk-cli] New `cosmos-sdk-cli` tool to quickly initialize a new
SDK-based project
- [scripts] added log output monitoring to DataDog using Ansible scripts
IMPROVEMENTS

- [x/gov] Initial governance parameters can now be set in the genesis file
- [x/stake] \#1815 Sped up the processing of `EditValidator` txs.
- [config] \#1930 Transactions indexer indexes all tags by default.
- [ci] [#2057](https://github.com/cosmos/cosmos-sdk/pull/2057) Run `make localnet-start` on every commit and ensure network reaches at least 10 blocks
* SDK
- [baseapp] \#1587 Allow any alphanumeric character in route
- [baseapp] Allow any alphanumeric character in route
- [tools] Remove `rm -rf vendor/` from `make get_vendor_deps`

- [x/bank] Unit tests are now table-driven
- [tests] Add tests to example apps in docs
- [tests] Fixes ansible scripts to work with AWS too

## v0.24.0 PENDING
^--- PENDING wasn't purged on sdk v0.23.0 release.
BREAKING CHANGES
* Update to tendermint v0.23.0. This involves removing crypto.Pubkey,

## PENDING
BREAKING CHANGES
* API
- \#1880 and \#2000 [x/stake] changed the endpoints to be more REST-ful
* Update to tendermint v0.22.5. This involves changing all of the cryptography imports. [Ref](https://github.com/tendermint/tendermint/pull/1966)

* `gaiacli stake create-validator`
* `gaiacli stake edit-validator`
* [baseapp] NewBaseApp constructor now takes sdk.TxDecoder as argument instead of wire.Codec
* [x/auth] Default TxDecoder can be found in `x/auth` rather than baseapp
* \#1606 The following CLI commands have been switched to use `--from`
* `gaiacli stake create-validator --address-validator`
* `gaiacli stake edit-validator --address-validator`
* `gaiacli stake delegate --address-delegator`
* `gaiacli stake unbond begin --address-delegator`
* `gaiacli stake unbond complete --address-delegator`

* [cli] #1551: Officially removed `--name` from CLI commands
* [cli] Genesis/key creation (`init`) now supports user-provided key passwords
* [cli] unsafe_reset_all, show_validator, and show_node_id have been renamed to unsafe-reset-all, show-validator, and show-node-id
* [cli] \#1901 Flag --address-validator renamed to --validator in stake and slashing commands
* [types] \#1901 Validator interface's GetOwner() renamed to GetOperator()
* [x/stake] \#1901 Validator type's Owner field renamed to Operator; Validator's GetOwner() renamed accordingly to comply with the SDK's Validator interface.
* Gaia REST API (`gaiacli advanced rest-server`)
* [x/stake] Validator.Owner renamed to Validator.Operator
* Gaia CLI (`gaiacli`)
* [x/stake] Validator.Owner renamed to Validator.Operator
* [cli] unsafe_reset_all, show_validator, and show_node_id have been renamed to unsafe-reset-all, show-validator, and show-node-id
* [cli] \#1983 --print-response now defaults to true in commands that create and send a transaction
* [cli] \#1983 you can now pass --pubkey or --address to gaiacli keys show to return a plaintext representation of the key's address or public key for use with other commands
* [cli] \#2061 changed proposalID in governance REST endpoints to proposal-id
* [cli] \#2014 `gaiacli advanced` no longer exists - to access `ibc`, `rest-server`, and `validator-set` commands use `gaiacli ibc`, `gaiacli rest-server`, and `gaiacli tendermint`, respectively
* Gaia
* Make the transient store key use a distinct store key. [#2013](https://github.com/cosmos/cosmos-sdk/pull/2013)
* [x/stake] \#1901 Validator type's Owner field renamed to Operator; Validator's GetOwner() renamed accordingly to comply with the SDK's Validator interface.

## Create your Own Testnet
To create your own testnet, first each validator will need to install gaiad and run gen-tx
```bash
gaiad init gen-tx --name <account_name>
```
This populations `$HOME/.gaiad/gen-tx/` with a json file.
Now these json files need to be aggregated together via Github, a Google form, pastebin or other methods.
Place all files on one computer in `$HOME/.gaiad/gen-tx/`
```bash
gaiad init --gen-txs -o --chain=<chain-name>
```
This will generate a `genesis.json` in `$HOME/.gaiad/config/genesis.json` distribute this file to all validators on your testnet.
### Export state
To export state and reload (useful for testing purposes):
```
gaiad export > genesis.json; cp genesis.json ~/.gaiad/config/genesis.json; gaiad start
```

## Abstract
Having the ability to sign messages off-chain has proven to be a fundamental aspect
of nearly any blockchain. The notion of signing messages off-chain has many
added benefits such as saving on computational costs and reducing transaction
throughput and overhead. Within the context of the Cosmos, some of the major
applications of signing such data includes, but is not limited to, providing a
cryptographic secure and verifiable means of proving validator identity and
possibly associating it with some other framework or organization. In addition,
having the ability to sign Cosmos messages with a Ledger or similar HSM device.
A standardized protocol for hashing, signing, and verifying messages that can be
implemented by the Cosmos SDK and other third-party organizations is needed. Such a
standardized protocol subscribes to the following:
* Contains a specification of human-readable and machine-verifiable typed structured data
* Contains a framework for deterministic and injective encoding of structured data
* Utilizes cryptographic secure hashing and signing algorithms
* A framework for supporting extensions and domain separation
* Is invulnerable to chosen ciphertext attacks
* Has protection against potentially signing transactions a user did not intend to
This specification is only concerned with the rationale and the standardized
implementation of Cosmos signed messages. It does **not** concern itself with the
concept of replay attacks as that will be left up to the higher-level application
implementation. If you view signed messages in the means of authorizing some
action or data, then such an application would have to either treat this as
idempotent or have mechanisms in place to reject known signed messages.
## Preliminary
The Cosmos message signing protocol will be parameterized with a cryptographic
secure hashing algorithm `SHA-256` and a signing algorithm `S` that contains
the operations `sign` and `verify` which provide a digital signature over a set
of bytes and verification of a signature respectively.
Note, our goal here is not to provide context and reasoning about why necessarily
these algorithms were chosen apart from the fact they are the defacto algorithms
used in Tendermint and the Cosmos SDK and that they satisfy our needs for such
cryptographic algorithms such as having resistance to collision and second
pre-image attacks, as well as being [deterministic](https://en.wikipedia.org/wiki/Hash_function#Determinism) and [uniform](https://en.wikipedia.org/wiki/Hash_function#Uniformity).
## Specification
Tendermint has a well established protocol for signing messages using a canonical
JSON representation as defined [here](https://github.com/tendermint/tendermint/blob/master/types/canonical_json.go).
An example of such a canonical JSON structure is Tendermint's vote structure:
```golang
type CanonicalJSONVote struct {
ChainID string `json:"@chain_id"`
Type string `json:"@type"`
BlockID CanonicalJSONBlockID `json:"block_id"`
Height int64 `json:"height"`
Round int `json:"round"`
Timestamp string `json:"timestamp"`
VoteType byte `json:"type"`
}
```
With such canonical JSON structures, the specification requires that they include
meta fields: `@chain_id` and `@type`. These meta fields are reserved and must be
included. They are both of type `string`. In addition, fields must be ordered
in lexicographically ascending order.
For the purposes of signing Cosmos messages, the `@chain_id` field must correspond
to the Cosmos chain identifier. The user-agent should **refuse** signing if the
`@chain_id` field does not match the currently active chain! The `@type` field
must equal the constant `"message"`. The `@type` field corresponds to the type of
structure the user will be signing in an application. For now, a user is only
allowed to sign bytes of valid ASCII text ([see here](https://github.com/tendermint/tendermint/blob/master/libs/common/string.go#L61-L74)).
However, this will change and evolve to support additional application-specific
structures that are human-readable and machine-verifiable ([see Future Adaptations](#futureadaptations)).
Thus, we can have a canonical JSON structure for signing Cosmos messages using
the [JSON schema](http://json-schema.org/) specification as such:
```json
{
"$schema": "http://json-schema.org/draft-04/schema#",
"$id": "cosmos/signing/typeData/schema",
"title": "The Cosmos signed message typed data schema.",
"type": "object",
"properties": {
"@chain_id": {
"type": "string",
"description": "The corresponding Cosmos chain identifier.",
"minLength": 1
},
"@type": {
"type": "string",
"description": "The message type. It must be 'message'.",
"enum": [
"message"
]
},
"text": {
"type": "string",
"description": "The valid ASCII text to sign.",
"pattern": "^[\\x20-\\x7E]+$",
"minLength": 1
}
},
"required": [
"@chain_id",
"@type",
"text"
]
}
```
e.g.
```json
{
"@chain_id": "1",
"@type": "message",
"text": "Hello, you can identify me as XYZ on keybase."
}
```
## Future Adaptations
As applications can vary greatly in domain, it will be vital to support both
domain separation and human-readable and machine-verifiable structures.
Domain separation will allow for application developers to prevent collisions of
otherwise identical structures. It should be designed to be unique per application
use and should directly be used in the signature encoding itself.
Human-readable and machine-verifiable structures will allow end users to sign
more complex structures, apart from just string messages, and still be able to
know exactly what they are signing (opposed to signing a bunch of arbitrary bytes).
Thus, in the future, the Cosmos signing message specification will be expected
to expand upon it's canonical JSON structure to include such functionality.
## API
Application developers and designers should formalize a standard set of APIs that
adhere to the following specification:
-----
### **cosmosSignBytes**
Params:
* `data`: the Cosmos signed message canonical JSON structure
* `address`: the Bech32 Cosmos account address to sign data with
Returns:
* `signature`: the Cosmos signature derived using signing algorithm `S`
-----
### Examples
Using the `secp256k1` as the DSA, `S`:
```javascript
data = {
"@chain_id": "1",
"@type": "message",
"text": "I hereby claim I am ABC on Keybase!"
}
cosmosSignBytes(data, "cosmosaccaddr1pvsch6cddahhrn5e8ekw0us50dpnugwnlfngt3")
> "0x7fc4a495473045022100dec81a9820df0102381cdbf7e8b0f1e2cb64c58e0ecda1324543742e0388e41a02200df37905a6505c1b56a404e23b7473d2c0bc5bcda96771d2dda59df6ed2b98f8"

`gaiacli` is the command line interface to manage accounts and transactions on Cosmos testnets. Here is a list of useful `gaiacli` commands, including usage examples.
### Key Types
### Keys
#### Key Types
There are three types of key representations that are used:
- `cosmosaccaddr`
- Derived from account keys generated by `gaiacli keys add`
- Used to receive funds
- e.g. `cosmosaccaddr15h6vd5f0wqps26zjlwrc6chah08ryu4hzzdwhc`

- `cosmosvalpub`
- Generated when the node is created with `gaiad init`.
- Get this value with `gaiad tendermint show-validator`

### Delegate
### Staking
#### Set up a Validator
Please refer to the [Validator Setup](https://cosmos.network/docs/validators/validator-setup.html) section for a more complete guide on how to set up a validator-candidate.
#### Delegate to a Validator
On the upcoming mainnet, you can delegate `atom` to a validator. These [delegators](/resources/delegators-faq) can receive part of the validator's fee revenue. Read more about the [Cosmos Token Model](https://github.com/cosmos/cosmos/raw/master/Cosmos_Token_Model.pdf).
### Bond Tokens
##### Query Validators
On the testnet, we delegate `steak` instead of `atom`. Here's how you can bond tokens to a testnet validator:
You can query the list of all validators of a specific chain:
```bash
gaiacli stake validators

### Unbond Tokens
##### Query Delegations
If for any reason the validator misbehaves, or you want to unbond a certain amount of tokens, use this following command. You can unbond a specific amount of`shares`\(eg:`12.1`\) or all of them \(`MAX`\).
Once submitted a delegation to a validator, you can see it's information by using the following command:
```bash
gaiacli stake delegation \
--address-delegator=<account_cosmosaccaddr> \
--address-validator=$(gaiad tendermint show-validator)
```
Or if you want to check all your current delegations with disctinct validators:
```bash
gaiacli stake delegations <account_cosmosaccaddr>
```
You can also get previous delegation(s) status by adding the `--height` flag.
#### Unbond Tokens
If for any reason the validator misbehaves, or you just want to unbond a certain amount of tokens, use this following command. You can unbond a specific `shares-amount` (eg:`12.1`\) or a `shares-percent` (eg:`25`) with the corresponding flags.
```bash
gaiacli stake unbond begin \
--validator=$(gaiad tendermint show-validator) \
--shares=MAX \
--address-validator=$(gaiad tendermint show-validator) \
--shares-percent=100 \
--from=<key_name> \
--chain-id=gaia-7005
--chain-id=<chain_id>
```
Later you must use the `gaiacli stake unbond complete` command to finish
unbonding at which point you can can check your balance and your stake
delegation to see that the unbonding went through successfully.
Later you must complete the unbonding process by using the `gaiacli stake unbond complete` command:
```bash
gaiacli account <account_cosmosaccaddr>

--address-validator=$(gaiad tendermint show-validator) \
```
Or if you want to check all your current unbonding-delegations with disctinct validators:
```bash
gaiacli stake unbonding-delegations <account_cosmosaccaddr>
```
You can also get previous unbonding-delegation(s) status by adding the `--height` flag.
#### Redelegate Tokens
A redelegation is a type delegation that allows you to bond illiquid tokens from one validator to another:
```bash
gaiacli stake redelegate begin \
--address-validator-source=$(gaiad tendermint show-validator) \
--address-validator-dest=<account_cosmosaccaddr> \
--shares-percent=50 \
--from=<key_name> \
--chain-id=<chain_id>
```
Here you can also redelegate a specific `shares-amount` or a `shares-percent` with the corresponding flags.
Later you must complete the redelegation process by using the `gaiacli stake redelegate complete` command:
```bash
gaiacli stake unbond complete \
--address-validator=$(gaiad tendermint show-validator) \
--from=<key_name> \
--chain-id=<chain_id>
```
##### Query Redelegations
Once you begin an redelegation, you can see it's information by using the following command:
```bash
gaiacli stake redelegation \
--address-delegator=<account_cosmosaccaddr> \
--address-validator-source=$(gaiad tendermint show-validator) \
--address-validator-dest=<account_cosmosaccaddr> \
```
Or if you want to check all your current unbonding-delegations with disctinct validators:
```bash
gaiacli stake redelegations <account_cosmosaccaddr>
```
You can also get previous redelegation(s) status by adding the `--height` flag.
### Governance
Governance is the process from which users in the Cosmos Hub can come to consensus on software upgrades, parameters of the mainnet or on custom text proposals. This is done through voting on proposals, which will be submitted by `Atom` holders on the mainnet.
Some considerations about the voting process:
- Voting is done by bonded `Atom` holders on a 1 bonded `Atom` 1 vote basis
- Delegators inherit the vote of their validator if they don't vote
- **Validators MUST vote on every proposal**. If a validator does not vote on a proposal, they will be **partially slashed**
- Votes are tallied at the end of the voting period (2 weeks on mainnet). Each address can vote multiple times to update its `Option` value (paying the transaction fee each time), only the last casted vote will count as valid
- Voters can choose between options `Yes`, `No`, `NoWithVeto` and `Abstain`
At the end of the voting period, a proposal is accepted if `(YesVotes/(YesVotes+NoVotes+NoWithVetoVotes))>1/2` and `(NoWithVetoVotes/(YesVotes+NoVotes+NoWithVetoVotes))<1/3`. It is rejected otherwise
For more information about the governance process and how it works, please check out the Governance module [specification](https://github.com/cosmos/cosmos-sdk/tree/develop/docs/spec/governance).
#### Create a Governance proposal
In order to create a governance proposal, you must submit an initial deposit along with the proposal details:
- `title`: Title of the proposal
- `description`: Description of the proposal
- `type`: Type of proposal. Must be of value _Text_ (types _SoftwareUpgrade_ and _ParameterChange_ not supported yet).
```bash
gaiacli gov submit-proposal \
--title=<title> \
--description=<description> \
--type=<Text/ParameterChange/SoftwareUpgrade> \
--proposer=<account_cosmosaccaddr> \
--deposit=<40steak> \
--from=<name> \
--chain-id=<chain_id>
```
##### Query proposals
Once created, you can now query information of the proposal:
```bash
gaiacli gov query-proposal \
--proposal-id=<proposal_id>
```
Or query all available proposals:
```bash
gaiacli gov query-proposals
```
You can also query proposals filtered by `voter` or `depositer` by using the corresponding flags.
#### Increase deposit
In order for a proposal to be broadcasted to the network, the amount deposited must be above a `minDeposit` value (default: `10 steak`). If the proposal you previously created didn't meet this requirement, you can still increase the total amount deposited to activate it. Once the minimum deposit is reached, the proposal enters voting period:
```bash
gaiacli gov deposit \
--proposal-id=<proposal_id> \
--depositer=<account_cosmosaccaddr> \
--deposit=<200steak> \
--from=<name> \
--chain-id=<chain_id>
```
> _NOTE_: Proposals that don't meet this requirement will be deleted after `MaxDepositPeriod` is reached.
#### Vote on a proposal
After a proposal's deposit reaches the `MinDeposit` value, the voting period opens. Bonded `Atom` holders can then cast vote on it:
```bash
gaiacli gov vote \
--proposal-id=<proposal_id> \
--voter=<account_cosmosaccaddr> \
--option=<Yes/No/NoWithVeto/Abstain> \
--from=<name> \
--chain-id=<chain_id>
```
##### Query vote
Check the vote with the option you just submitted:
```bash
gaiacli gov query-vote \
--proposal-id=<proposal_id> \
--voter=<account_cosmosaccaddr>
```
#### Query Parameters
You can get the current parameters that define high level settings for staking:
```
gaiacli stake parameters
```
With the above command you will get the values for:
- Maximum and minumum Inflation rate
- Maximum annual change in inflation rate,
- Goal of bonded tokens (%)
- Unbonding time
- Maximum numbers of validators
- Coin denomination for staking
All this values can be updated though a `governance` process by submitting a parameter change `proposal`.
#### Query Pool
A staking `Pool` defines the dynamic parameters of the current state. You can query them with the following command:
```
gaiacli stake pool
```
With the `pool` command you will get the values for:
- Loose and bonded tokens
- Token supply
- Current anual inflation and the block in which the last inflation was processed
- Last recorded bonded shares

## Vesting
### Intro and Requirements
This paper specifies vesting account implementation for the Cosmos Hub.
The requirements for this vesting account is that it should be initialized during genesis with
a starting balance X coins and a vesting endtime T. The owner of this account should be able to delegate to validators
and vote with locked coins, however they cannot send locked coins to other accounts until those coins have been unlocked.
The vesting account should also be able to spend any coins it receives from other users.
Thus, the bank module's `MsgSend` handler should error if a vesting account is trying to send an amount that exceeds their
unlocked coin amount.
### Implementation
##### Vesting Account implementation
NOTE: `Now = ctx.BlockHeader().Time`
```go
type VestingAccount interface {
Account
AssertIsVestingAccount() // existence implies that account is vesting.
// Calculates amount of coins that can be sent to other accounts given the current time
SendableCoins(sdk.Context) sdk.Coins
}
// Implements Vesting Account
// Continuously vests by unlocking coins linearly with respect to time
type ContinuousVestingAccount struct {
BaseAccount
OriginalVestingCoins sdk.Coins // Coins in account on Initialization
ReceivedCoins sdk.Coins // Coins received from other accounts
SentCoins sdk.Coins // Coins sent to other accounts
// StartTime and EndTime used to calculate how much of OriginalCoins is unlocked at any given point
StartTime time.Time
EndTime time.Time
}
// Uses time in context to calculate total unlocked coins
SendableCoins(vacc ContinuousVestingAccount, ctx sdk.Context) sdk.Coins:
// Coins unlocked by vesting schedule
unlockedCoins := ReceivedCoins - SentCoins + OriginalVestingCoins * (Now - StartTime) / (EndTime - StartTime)
// Must still check for currentCoins constraint since some unlocked coins may have been delegated.
currentCoins := vacc.BaseAccount.GetCoins()
// min will return sdk.Coins with each denom having the minimum amount from unlockedCoins and currentCoins
return min(unlockedCoins, currentCoins)
```
The `VestingAccount` interface is used to assert that an account is a vesting account like so:
```go
vacc, ok := acc.(VestingAccount); ok
```
as well as to calculate the SendableCoins at any given moment.
The `ContinuousVestingAccount` struct implements the Vesting account interface. It uses `OriginalVestingCoins`, `ReceivedCoins`,
`SentCoins`, `StartTime`, and `EndTime` to calculate how many coins are sendable at any given point.
Since the vesting restrictions need to be implemented on a per-module basis, the `ContinuousVestingAccount` implements
the `Account` interface exactly like `BaseAccount`. Thus, `ContinuousVestingAccount.GetCoins()` will return the total of
both locked coins and unlocked coins currently in the account. Delegated coins are deducted from `Account.GetCoins()`, but do not count against unlocked coins because they are still at stake and will be reinstated (partially if slashed) after waiting the full unbonding period.
##### Changes to Keepers/Handler
Since a vesting account should be capable of doing everything but sending with its locked coins, the restriction should be
handled at the `bank.Keeper` level. Specifically in methods that are explicitly used for sending like
`sendCoins` and `inputOutputCoins`. These methods must check that an account is a vesting account using the check described above.
```go
if acc is VestingAccount and Now < vestingAccount.EndTime:
// Check if amount is less than currently allowed sendable coins
if msg.Amount > vestingAccount.SendableCoins(ctx) then fail
else:
vestingAccount.SentCoins += msg.Amount
else:
// Account has fully vested, treat like regular account
if msg.Amount > account.GetCoins() then fail
// All checks passed, send the coins
SendCoins(inputs, outputs)
```
Coins that are sent to a vesting account after initialization by users sending them coins should be spendable
immediately after receiving them. Thus, handlers (like staking or bank) that send coins that a vesting account did not
originally own should increment `ReceivedCoins` by the amount sent.
Unlocked coins that are sent to other accounts will increment the vesting account's `SentCoins` attribute.
CONTRACT: Handlers SHOULD NOT update `ReceivedCoins` if they were originally sent from the vesting account. For example, if a vesting account unbonds from a validator, their tokens should be added back to account but staking handlers SHOULD NOT update `ReceivedCoins`.
However when a user sends coins to vesting account, then `ReceivedCoins` SHOULD be incremented.
### Initializing at Genesis
To initialize both vesting accounts and base accounts, the `GenesisAccount` struct will include an EndTime. Accounts meant to be
BaseAccounts will have `EndTime = 0`. The `initChainer` method will parse the GenesisAccount into BaseAccounts and VestingAccounts
as appropriate.
```go
type GenesisAccount struct {
Address sdk.AccAddress `json:"address"`
GenesisCoins sdk.Coins `json:"coins"`
EndTime int64 `json:"lock"`
}
initChainer:
for gacc in GenesisAccounts:
baseAccount := BaseAccount{
Address: gacc.Address,
Coins: gacc.GenesisCoins,
}
if gacc.EndTime != 0:
vestingAccount := ContinuouslyVestingAccount{
BaseAccount: baseAccount,
OriginalVestingCoins: gacc.GenesisCoins,
StartTime: RequestInitChain.Time,
EndTime: gacc.EndTime,
}
AddAccountToState(vestingAccount)
else:
AddAccountToState(baseAccount)

### Formulas
`OriginalVestingCoins`: Amount of coins in account at Genesis
`CurrentCoins`: Coins currently in the baseaccount (both locked and unlocked: `vestingAccount.GetCoins`)
`ReceivedCoins`: Coins received from other accounts (always unlocked)
`LockedCoins`: Coins that are currently locked
`Delegated`: Coins that have been delegated (no longer in account; may be locked or unlocked)
`Sent`: Coins sent to other accounts (MUST be unlocked)
Maximum amount of coins vesting schedule allows to be sent:
`ReceivedCoins - SentCoins + OriginalVestingCoins * (Now - StartTime) / (EndTime - StartTime)`
`ReceivedCoins - SentCoins + OriginalVestingCoins - LockedCoins`
Coins currently in Account:
`CurrentCoins = OriginalVestingCoins + ReceivedCoins - Delegated - Sent`
`CurrentCoins = vestingAccount.GetCoins()`
**Maximum amount of coins spendable right now:**
`min( ReceivedCoins - SentCoins + OriginalVestingCoins - LockedCoins, CurrentCoins )`

### Track Validator Signing Information
In order to keep track of a validator's signatures in the past you can do so by using the `signing-info` command:
```bash
gaiacli stake signing-information <validator-pubkey>\
--chain-id=<chain_id>
```
### Unrevoke Validator
When a validator is `Revoked` for downtime, you must submit an `Unrevoke` transaction in order to be able to get block proposer rewards again (depends on the zone fee distribution).
```bash
gaiacli stake unrevoke \
--from=<key_name> \
--chain-id=<chain_id>
--validator=<account_cosmosaccaddr> \

Your validator has become auto-unbonded. In `gaia-7005`, we unbond validators if they do not vote on `50` of the last `100` blocks. Since blocks are proposed every ~2 seconds, a validator unresponsive for ~100 seconds will become unbonded. This usually happens when your `gaiad` process crashes.
