## Forking
|

|
|
@ -85,7 +85,7 @@ For instance, to create a fork and work on a branch of it, I would:
|
|||
- Create the fork on github, using the fork button.
|
||||
- Go to the original repo checked out locally (i.e. `$GOPATH/src/github.com/cosmos/cosmos-sdk`)
|
||||
- `git remote rename origin upstream`
|
||||
- `git remote add origin git@github.com:ebuchman/basecoin.git`
|
||||
- `git remote add origin git@github.com:ebuchman/cosmos-sdk.git`
|
||||
|
||||
Now `origin` refers to my fork and `upstream` refers to the Cosmos-SDK version.
|
||||
So I can `git push -u origin master` to update my fork, and make pull requests to Cosmos-SDK from there.

# Basecoin Example
|
||||
|
||||
Here we explain how to get started with a basic Basecoin blockchain, how
|
||||
to send transactions between accounts using the ``basecli`` tool, and
|
||||
what is happening under the hood.
|
||||
|
||||
## Setup and Install
|
||||
|
||||
You will need to have go installed on your computer. Please refer to the [cosmos testnet tutorial](https://cosmos.network/validators/tutorial), which will always have the most updated instructions on how to get setup with go and the cosmos repository.
|
||||
|
||||
Once you have go installed, run the command:
|
||||
|
||||
```
|
||||
go get github.com/cosmos/cosmos-sdk
|
||||
```
|
||||
|
||||
There will be an error stating `can't load package: package github.com/cosmos/cosmos-sdk: no Go files`, however you can ignore this error, it doesn't affect us. Now change directories to:
|
||||
|
||||
```
|
||||
cd $GOPATH/src/github.com/cosmos/cosmos-sdk
|
||||
```
|
||||
|
||||
And run :
|
||||
|
||||
```
|
||||
make tools // run make update_tools if you already had it installed
|
||||
make get_vendor_deps
|
||||
make install_examples
|
||||
```
|
||||
Then run `make install_examples`, which creates binaries for `basecli` and `basecoind`. You can look at the Makefile if you want to see the details on what these make commands are doing.
|
||||
|
||||
## Using basecli and basecoind
|
||||
|
||||
Check the versions by running:
|
||||
|
||||
```
|
||||
basecli version
|
||||
basecoind version
|
||||
```
|
||||
|
||||
They should read something like `0.17.1-5d18d5f`, but the versions will be constantly updating so don't worry if your version is higher that 0.17.1. That's a good thing.
|
||||
|
||||
Note that you can always check help in the terminal by running `basecli -h` or `basecoind -h`. It is good to check these out if you are stuck, because updates to the code base might slightly change the commands, and you might find the correct command in there.
|
||||
|
||||
Let's start by initializing the basecoind daemon. Run the command
|
||||
|
||||
```
|
||||
basecoind init
|
||||
```
|
||||
|
||||
And you should see something like this:
|
||||
|
||||
```
|
||||
{
|
||||
"chain_id": "test-chain-z77iHG",
|
||||
"node_id": "e14c5056212b5736e201dd1d64c89246f3288129",
|
||||
"app_message": {
|
||||
"secret": "pluck life bracket worry guilt wink upgrade olive tilt output reform census member trouble around abandon"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
This creates the `~/.basecoind folder`, which has config.toml, genesis.json, node_key.json, priv_validator.json. Take some time to review what is contained in these files if you want to understand what is going on at a deeper level.
|
||||
|
||||
|
||||
## Generating keys
|
||||
|
||||
The next thing we'll need to do is add the key from priv_validator.json to the gaiacli key manager. For this we need the 16 word seed that represents the private key, and a password. You can also get the 16 word seed from the output seen above, under `"secret"`. Then run the command:
|
||||
|
||||
```
|
||||
basecli keys add alice --recover
|
||||
```
|
||||
|
||||
Which will give you three prompts:
|
||||
|
||||
```
|
||||
Enter a passphrase for your key:
|
||||
Repeat the passphrase:
|
||||
Enter your recovery seed phrase:
|
||||
```
|
||||
|
||||
You just created your first locally stored key, under the name alice, and this account is linked to the private key that is running the basecoind validator node. Once you do this, the ~/.basecli folder is created, which will hold the alice key and any other keys you make. Now that you have the key for alice, you can start up the blockchain by running
|
||||
|
||||
```
|
||||
basecoind start
|
||||
```
|
||||
|
||||
You should see blocks being created at a fast rate, with a lot of output in the terminal.
|
||||
|
||||
Next we need to make some more keys so we can use the send transaction functionality of basecoin. Open a new terminal, and run the following commands, to make two new accounts, and give each account a password you can remember:
|
||||
|
||||
```
|
||||
basecli keys add bob
|
||||
basecli keys add charlie
|
||||
```
|
||||
|
||||
You can see your keys with the command:
|
||||
|
||||
```
|
||||
basecli keys list
|
||||
```
|
||||
|
||||
You should now see alice, bob and charlie's account all show up.
|
||||
|
||||
```
|
||||
NAME: ADDRESS: PUBKEY:
|
||||
alice cosmos1khygs0qh7gz3p4m39u00mjhvgvc2dcpxhsuh5f cosmospub1addwnpepq0w037u5g7y7lvdvsred2dehg90j84k0weyss5ynysf0nnnax74agrsxns6
|
||||
bob cosmos18se8tz6kwwfga6k2yjsu7n64e9z52nen29rhzz cosmospub1addwnpepqwe97n8lryxrzvamrvjfj24jys3uzf8wndfvqa2l7mh5nsv4jrvdznvyeg6
|
||||
charlie cosmos13wq5mklhn03ljpd4dkph5rflk5a3ssma2ag07q cosmospub1addwnpepqdmtxv35rrmv2dvcr3yhfyxj7dzrd4z4rnhmclksq4g55a4wpl54clvx33l
|
||||
```
|
||||
|
||||
|
||||
## Send transactions
|
||||
|
||||
Lets send bob and charlie some tokens. First, lets query alice's account so we can see what kind of tokens she has:
|
||||
|
||||
```
|
||||
basecli account cosmos1khygs0qh7gz3p4m39u00mjhvgvc2dcpxhsuh5f
|
||||
```
|
||||
|
||||
Where `cosmos1khygs0qh7gz3p4m39u00mjhvgvc2dcpxhsuh5f` is alice's address we got from running `basecli keys list`. You should see a large amount of "mycoin" there. If you search for bob's or charlie's address, the command will fail, because they haven't been added into the blockchain database yet since they have no coins. We need to send them some!
|
||||
|
||||
The following command will send coins from alice, to bob:
|
||||
|
||||
```
|
||||
basecli send --from=alice --amount=10000mycoin --to=cosmos18se8tz6kwwfga6k2yjsu7n64e9z52nen29rhzz
|
||||
--sequence=0 --chain-id=test-chain-AE4XQo
|
||||
```
|
||||
|
||||
Flag Descriptions:
|
||||
- `from` is the name you gave your key
|
||||
- `mycoin` is the name of the token for this basecoin demo, initialized in the genesis.json file
|
||||
- `sequence` is a tally of how many transactions have been made by this account. Since this is the first tx on this account, it is 0
|
||||
- `chain-id` is the unique ID that helps tendermint identify which network to connect to. You can find it in the terminal output from the gaiad daemon in the header block , or in the genesis.json file at `~/.basecoind/config/genesis.json`
|
||||
|
||||
Now if we check bobs account, it should have `10000 mycoin`. You can do so by running :
|
||||
|
||||
```
|
||||
basecli account cosmos18se8tz6kwwfga6k2yjsu7n64e9z52nen29rhzz
|
||||
```
|
||||
|
||||
Now lets send some from bob to charlie. Make sure you send less than bob has, otherwise the transaction will fail:
|
||||
|
||||
```
|
||||
basecli send --from=bob --amount=5000mycoin --to=cosmos13wq5mklhn03ljpd4dkph5rflk5a3ssma2ag07q
|
||||
--sequence=0 --chain-id=test-chain-AE4XQo
|
||||
```
|
||||
|
||||
Note how we use the ``--from`` flag to select a different account to send from.
|
||||
|
||||
Lets now try to send from bob back to alice:
|
||||
|
||||
```
|
||||
basecli send --from=bob --amount=3000mycoin --to=cosmos1khygs0qh7gz3p4m39u00mjhvgvc2dcpxhsuh5f
|
||||
--sequence=1 --chain-id=test-chain-AE4XQo
|
||||
```
|
||||
|
||||
Notice that the sequence is now 1, since we have already recorded bobs 1st transaction as `sequence 0`. Also note the ``hash`` value in the response in the terminal - this is the hash of the transaction. We can query for the transaction with this command:
|
||||
|
||||
```
|
||||
basecli tx <INSERT HASH HERE>
|
||||
```
|
||||
|
||||
It will return the details of the transaction hash, such as how many coins were send and to which address, and on what block it occurred.
|
||||
|
||||
That is the basic implementation of basecoin!
|
||||
|
||||
|
||||
## Reset the basecoind blockchain and basecli data
|
||||
|
||||
**WARNING:** Running these commands will wipe out any existing
|
||||
information in both the ``~/.basecli`` and ``~/.basecoind`` directories,
|
||||
including private keys. This should be no problem considering that basecoin
|
||||
is just an example, but it is always good to pay extra attention when
|
||||
you are removing private keys, in any scenario involving a blockchain.
|
||||
|
||||
To remove all the files created and refresh your environment (e.g., if
|
||||
starting this tutorial again or trying something new), the following
|
||||
commands are run:
|
||||
|
||||
```
|
||||
basecoind unsafe-reset-all
|
||||
rm -rf ~/.basecoind
|
||||
rm -rf ~/.basecli
|
||||
```
|
||||
|
||||
## Technical Details on how Basecoin Works
|
||||
|
||||
This section describes some of the more technical aspects for what is going on under the hood of Basecoin.
|
||||
|
||||
## Proof
|
||||
|
||||
Even if you don't see it in the UI, the result of every query comes with
|
||||
a proof. This is a Merkle proof that the result of the query is actually
|
||||
contained in the state. And the state's Merkle root is contained in a
|
||||
recent block header. Behind the scenes, ``basecli`` will not only
|
||||
verify that this state matches the header, but also that the header is
|
||||
properly signed by the known validator set. It will even update the
|
||||
validator set as needed, so long as there have not been major changes
|
||||
and it is secure to do so. So, if you wonder why the query may take a
|
||||
second... there is a lot of work going on in the background to make sure
|
||||
even a lying full node can't trick your client.
|
||||
|
||||
## Accounts and Transactions
|
||||
|
||||
For a better understanding of how to further use the tools, it helps to
|
||||
understand the underlying data structures, so lets look at accounts and transactions.
|
||||
|
||||
### Accounts
|
||||
|
||||
The Basecoin state consists entirely of a set of accounts. Each account
|
||||
contains an address, a public key, a balance in many different coin denominations,
|
||||
and a strictly increasing sequence number for replay protection. This
|
||||
type of account was directly inspired by accounts in Ethereum, and is
|
||||
unlike Bitcoin's use of Unspent Transaction Outputs (UTXOs).
|
||||
|
||||
```
|
||||
type BaseAccount struct {
|
||||
Address sdk.Address `json:"address"`
|
||||
Coins sdk.Coins `json:"coins"`
|
||||
PubKey crypto.PubKey `json:"public_key"`
|
||||
Sequence int64 `json:"sequence"`
|
||||
}
|
||||
```
|
||||
|
||||
You can also add more fields to accounts, and basecoin actually does so. Basecoin
|
||||
adds a Name field in order to show how easily the base account structure can be
|
||||
modified to suit any applications needs. It takes the `auth.BaseAccount` we see above,
|
||||
and extends it with `Name`.
|
||||
|
||||
```
|
||||
type AppAccount struct {
|
||||
auth.BaseAccount
|
||||
Name string `json:"name"`
|
||||
}
|
||||
```
|
||||
|
||||
Within accounts, coin balances are stored. Basecoin is a multi-asset cryptocurrency, so each account can have many
|
||||
different kinds of tokens, which are held in an array.
|
||||
|
||||
```
|
||||
type Coins []Coin
|
||||
|
||||
type Coin struct {
|
||||
Denom string `json:"denom"`
|
||||
Amount int64 `json:"amount"`
|
||||
}
|
||||
```
|
||||
|
||||
If you want to add more coins to a blockchain, you can do so manually in
|
||||
the ``~/.basecoin/genesis.json`` before you start the blockchain for the
|
||||
first time.
|
||||
|
||||
Accounts are serialized and stored in a Merkle tree under the key
|
||||
``base/a/<address>``, where ``<address>`` is the address of the account.
|
||||
Typically, the address of the account is the first 20-bytes of the ``sha256`` hash
|
||||
of the public key, but other formats are acceptable as well, as defined
|
||||
in the `Tendermint crypto
|
||||
library <https://github.com/tendermint/tendermint/tree/master/crypto>`__. The Merkle tree
|
||||
used in Basecoin is a balanced, binary search tree, which we call an
|
||||
`IAVL tree <https://github.com/tendermint/iavl>`__.
|
||||
|
||||
### Transactions
|
||||
|
||||
Basecoin defines a transaction type, the `SendTx`, which allows tokens
|
||||
to be sent to other accounts. The `SendTx` takes a list of inputs and
|
||||
a list of outputs, and transfers all the tokens listed in the inputs
|
||||
from their corresponding accounts to the accounts listed in the output.
|
||||
The `SendTx` is structured as follows:
|
||||
```
|
||||
type SendTx struct {
|
||||
Gas int64 `json:"gas"`
|
||||
Fee Coin `json:"fee"`
|
||||
Inputs []TxInput `json:"inputs"`
|
||||
Outputs []TxOutput `json:"outputs"`
|
||||
}
|
||||
|
||||
type TxInput struct {
|
||||
Address []byte `json:"address"` // Hash of the PubKey
|
||||
Coins Coins `json:"coins"` //
|
||||
Sequence int `json:"sequence"` // Must be 1 greater than the last committed TxInput
|
||||
Signature []byte `json:"signature"` // Depends on the PubKey type and the whole Tx
|
||||
PubKey crypto.PubKey `json:"pub_key"` // Is present iff Sequence == 0
|
||||
}
|
||||
|
||||
type TxOutput struct {
|
||||
Address []byte `json:"address"` // Hash of the PubKey
|
||||
Coins Coins `json:"coins"` //
|
||||
}
|
||||
```
|
||||
Note the `SendTx` includes a field for `Gas` and `Fee`. The
|
||||
`Gas` limits the total amount of computation that can be done by the
|
||||
transaction, while the `Fee` refers to the total amount paid in fees.
|
||||
This is slightly different from Ethereum's concept of `Gas` and
|
||||
`GasPrice`, where `Fee = Gas x GasPrice`. In Basecoin, the `Gas`
|
||||
and `Fee` are independent, and the `GasPrice` is implicit.
|
||||
|
||||
In Basecoin, the `Fee` is meant to be used by the validators to inform
|
||||
the ordering of transactions, like in Bitcoin. And the `Gas` is meant
|
||||
to be used by the application plugin to control its execution. There is
|
||||
currently no means to pass `Fee` information to the Tendermint
|
||||
validators, but it will come soon... so this version of Basecoin does
|
||||
not actually fully implement fees and gas, but it still allows us
|
||||
to send transactions between accounts.
|
||||
|
||||
Note also that the `PubKey` only needs to be sent for
|
||||
`Sequence == 0`. After that, it is stored under the account in the
|
||||
Merkle tree and subsequent transactions can exclude it, using only the
|
||||
`Address` to refer to the sender. Ethereum does not require public
|
||||
keys to be sent in transactions as it uses a different elliptic curve
|
||||
scheme which enables the public key to be derived from the signature
|
||||
itself.
|
||||
|
||||
Finally, note that the use of multiple inputs and multiple outputs
|
||||
allows us to send many different types of tokens between many different
|
||||
accounts at once in an atomic transaction. Thus, the `SendTx` can
|
||||
serve as a basic unit of decentralized exchange. When using multiple
|
||||
inputs and outputs, you must make sure that the sum of coins of the
|
||||
inputs equals the sum of coins of the outputs (no creating money), and
|
||||
that all accounts that provide inputs have signed the transaction.

# Oracle Module
|
||||
|
||||
`x/oracle` provides a way to receive external information(real world price, events from other chains, etc.) with validators' vote. Each validator make transaction which contains those informations, and Oracle aggregates them until the supermajority signed on it. After then, Oracle sends the information to the actual module that processes the information, and prune the votes from the state.
|
||||
|
||||
## Integration
|
||||
|
||||
See `x/oracle/oracle_test.go` for the code that using Oracle
|
||||
|
||||
To use Oracle in your module, first define a `payload`. It should implement `oracle.Payload` and contain nessesary information for your module. Including nonce is recommended.
|
||||
|
||||
```go
|
||||
type MyPayload struct {
|
||||
Data int
|
||||
Nonce int
|
||||
}
|
||||
```
|
||||
|
||||
When you write a payload, its `.Route()` should return same route with your module is registered on the router. It is because `oracle.Msg` inherits `.Route()` from its embedded payload and it should be handled on the user modules.
|
||||
|
||||
Then route every incoming `oracle.Msg` to `oracle.Keeper.Handler()` with the function that implements `oracle.Handler`.
|
||||
|
||||
```go
|
||||
func NewHandler(keeper Keeper) sdk.Handler {
|
||||
return func(ctx sdk.Context, msg sdk.Msg) sdk.Result {
|
||||
switch msg := msg.(type) {
|
||||
case oracle.Msg:
|
||||
return keeper.oracle.Handle(ctx sdk.Context, p oracle.Payload) sdk.Error {
|
||||
switch p := p.(type) {
|
||||
case MyPayload:
|
||||
return handleMyPayload(ctx, keeper, p)
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
In the previous example, the keeper has an `oracle.Keeper`. `oracle.Keeper`s are generated by `NewKeeper`.
|
||||
|
||||
```go
|
||||
func NewKeeper(key sdk.StoreKey, cdc *codec.Codec, valset sdk.ValidatorSet, supermaj sdk.Dec, timeout int64) Keeper {
|
||||
return Keeper {
|
||||
cdc: cdc,
|
||||
key: key,
|
||||
|
||||
// ValidatorSet to get validators infor
|
||||
valset: valset,
|
||||
|
||||
// The keeper will pass payload
|
||||
// when more than 2/3 signed on it
|
||||
supermaj: supermaj,
|
||||
// The keeper will prune votes after 100 blocks from last sign
|
||||
timeout: timeout,
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Now the validators can send `oracle.Msg`s with `MyPayload` when they want to witness external events.

In the Cosmos SDK, you can see the application of this principle in the

[basecoin examples folder](../examples/basecoin).

[gaia app](../gaia/app/app.go).

|

|

package app
|
||||

func (app *BasecoinApp) initRouterHandlers() {

|

// All handlers must be added here.
|
||||
// The order matters.
|
||||
app.router.AddRoute("bank", bank.NewHandler(app.accountKeeper))
|
||||
app.router.AddRoute("sketchy", sketchy.NewHandler())

}

// register message routes

app.Router().

AddRoute(staking.RouterKey, staking.NewHandler(app.stakingKeeper)).

AddRoute(distr.RouterKey, distr.NewHandler(app.distrKeeper)).

AddRoute(slashing.RouterKey, slashing.NewHandler(app.slashingKeeper)).
|

AddRoute(gov.RouterKey, gov.NewHandler(app.govKeeper))
|

```
|

|

In the Basecoin example, the sketchy handler isn't provided an account
|

mapper, which does provide the bank handler with the capability (in

conjunction with the context of a transaction run).
