# Building Quorum
Clone the repository and build the source:
```
git clone https://github.com/jpmorganchase/quorum.git
cd quorum
make all
make test
```
Binaries are placed within `./build/bin`, most notably `geth` and `bootnode`. Either add this directory to your `$PATH` or copy those two bins into your PATH:
```sh
# assumes that /usr/local/bin is in your PATH
cp ./build/bin/geth ./build/bin/bootnode /usr/local/bin/

# Hacking on Quorum / various notes
## Testing with Constellation
### `tm.conf`
Replace with appropriate absolute paths:
TODO(joel): figure out how to use relative paths
```
url = "http://127.0.0.1:9000/"
port = 9000
socket = "/Users/joel/go/src/github.com/ethereum/go-ethereum/qdata/tm.ipc"
othernodes = []
storage = "/Users/joel/go/src/github.com/ethereum/go-ethereum/qdata/constellation"
publickeys = ["/Users/joel/go/src/github.com/ethereum/go-ethereum/qdata/test.pub"]
privatekeys = ["/Users/joel/go/src/github.com/ethereum/go-ethereum/qdata/test.key"]
```
Run constellation:
```
> mkdir qdata
> constellation-node tm.conf
```
Now you should be able to run the private state tests as well: `env PRIVATE_CONFIG=(pwd)/tm.conf go test ./...`.
## How does private state work?
Let's look at the EVM structure:
```go
type EVM struct {
...
// StateDB gives access to the underlying state
StateDB StateDB
// Depth is the current call stack
depth int
...
publicState PublicState
privateState PrivateState
states [1027]*state.StateDB
currentStateDepth uint
readOnly bool
readOnlyDepth uint
}
```
The vanilla EVM has a call depth limit of 1024. Our `states` parallel the EVM call stack, recording as contracts in the public and private state call back and forth to each other. Note it doesn't have to be a "public -> private -> public -> private" back-and-forth chain. It can be any sequence of { public, private }.
The interface for calling is this `Push` / `Pop` sequence:
```go
evm.Push(getDualState(evm, addr))
defer func() { evm.Pop() }()
// ... do work in the pushed state
```
The definitions of `Push` and `Pop` are simple and important enough to duplicate here:
```go
func (env *EVM) Push(statedb StateDB) {
if env.privateState != statedb {
env.readOnly = true
env.readOnlyDepth = env.currentStateDepth
}
if castedStateDb, ok := statedb.(*state.StateDB); ok {
env.states[env.currentStateDepth] = castedStateDb
env.currentStateDepth++
}
env.StateDB = statedb
}
func (env *EVM) Pop() {
env.currentStateDepth--
if env.readOnly && env.currentStateDepth == env.readOnlyDepth {
env.readOnly = false
}
env.StateDB = env.states[env.currentStateDepth-1]
}
```
Note the invariant that `StateDB` always points to the current state db.
The other interesting note is read only mode. Any time we call from the private state into the public state (`env.privateState != statedb`), we require anything deeper to be *read only*. Private state transactions can't affect public state, so we throw an EVM exception on any mutating operation (`SELFDESTRUCT, CREATE, SSTORE, LOG0, LOG1, LOG2, LOG3, LOG4`). Question: have any more mutating operations been added? Question: could we not mutate deeper private state?

## Building the source
## Architecture
For prerequisites and detailed build instructions please read the
[Installation Instructions](https://github.com/ethereum/go-ethereum/wiki/Building-Ethereum)
on the wiki.

## Quickstart
or, to build the full suite of utilities:
The quickest way to get started with Quorum is using [VirtualBox](https://www.virtualbox.org/wiki/Downloads) and [Vagrant](https://www.vagrantup.com/downloads.html):
make all
## Executables
The go-ethereum project comes with several wrappers/executables found in the `cmd` directory.
| Command | Description |
|:----------:|-------------|
| **`geth`** | Our main Ethereum CLI client. It is the entry point into the Ethereum network (main-, test- or private net), capable of running as a full node (default) archive node (retaining all historical state) or a light node (retrieving data live). It can be used by other processes as a gateway into the Ethereum network via JSON RPC endpoints exposed on top of HTTP, WebSocket and/or IPC transports. `geth --help` and the [CLI Wiki page](https://github.com/ethereum/go-ethereum/wiki/Command-Line-Options) for command line options. |
| `abigen` | Source code generator to convert Ethereum contract definitions into easy to use, compile-time type-safe Go packages. It operates on plain [Ethereum contract ABIs](https://github.com/ethereum/wiki/wiki/Ethereum-Contract-ABI) with expanded functionality if the contract bytecode is also available. However it also accepts Solidity source files, making development much more streamlined. Please see our [Native DApps](https://github.com/ethereum/go-ethereum/wiki/Native-DApps:-Go-bindings-to-Ethereum-contracts) wiki page for details. |
| `bootnode` | Stripped down version of our Ethereum client implementation that only takes part in the network node discovery protocol, but does not run any of the higher level application protocols. It can be used as a lightweight bootstrap node to aid in finding peers in private networks. |
| `evm` | Developer utility version of the EVM (Ethereum Virtual Machine) that is capable of running bytecode snippets within a configurable environment and execution mode. Its purpose is to allow insolated, fine-grained debugging of EVM opcodes (e.g. `evm --code 60ff60ff --debug`). |
| `gethrpctest` | Developer utility tool to support our [ethereum/rpc-test](https://github.com/ethereum/rpc-tests) test suite which validates baseline conformity to the [Ethereum JSON RPC](https://github.com/ethereum/wiki/wiki/JSON-RPC) specs. Please see the [test suite's readme](https://github.com/ethereum/rpc-tests/blob/master/README.md) for details. |
| `rlpdump` | Developer utility tool to convert binary RLP ([Recursive Length Prefix](https://github.com/ethereum/wiki/wiki/RLP)) dumps (data encoding used by the Ethereum protocol both network as well as consensus wise) to user friendlier hierarchical representation (e.g. `rlpdump --hex CE0183FFFFFFC4C304050583616263`). |
| `swarm` | swarm daemon and tools. This is the entrypoint for the swarm network. `swarm --help` for command line options and subcommands. See https://swarm-guide.readthedocs.io for swarm documentation. |
| `puppeth` | a CLI wizard that aids in creating a new Ethereum network. |
## Running geth
Going through all the possible command line flags is out of scope here (please consult our
[CLI Wiki page](https://github.com/ethereum/go-ethereum/wiki/Command-Line-Options)), but we've
enumerated a few common parameter combos to get you up to speed quickly on how you can run your
own Geth instance.
### Full node on the main Ethereum network
By far the most common scenario is people wanting to simply interact with the Ethereum network:
create accounts; transfer funds; deploy and interact with contracts. For this particular use-case
the user doesn't care about years-old historical data, so we can fast-sync quickly to the current
state of the network. To do so:
```
$ geth --fast --cache=512 console
```sh
git clone https://github.com/jpmorganchase/quorum-examples
cd quorum-examples
vagrant up
# (should take 5 or so minutes)
vagrant ssh
```
This command will:
Now that you have a fully-functioning Quorum environment set up, let's run the 7-node cluster example. This will spin up several nodes with a mix of voters, block makers, and unprivileged nodes.
* Start geth in fast sync mode (`--fast`), causing it to download more data in exchange for avoiding
processing the entire history of the Ethereum network, which is very CPU intensive.
* Bump the memory allowance of the database to 512MB (`--cache=512`), which can help significantly in
sync times especially for HDD users. This flag is optional and you can set it as high or as low as
you'd like, though we'd recommend the 512MB - 2GB range.
* Start up Geth's built-in interactive [JavaScript console](https://github.com/ethereum/go-ethereum/wiki/JavaScript-Console),
(via the trailing `console` subcommand) through which you can invoke all official [`web3` methods](https://github.com/ethereum/wiki/wiki/JavaScript-API)
as well as Geth's own [management APIs](https://github.com/ethereum/go-ethereum/wiki/Management-APIs).
This too is optional and if you leave it out you can always attach to an already running Geth instance
with `geth attach`.
```sh
# (from within vagrant env, use `vagrant ssh` to enter)
ubuntu@ubuntu-xenial:~$ cd quorum-examples/7nodes
### Full node on the Ethereum test network
$ ./init.sh
# (output condensed for clarity)
[*] Cleaning up temporary data directories
[*] Configuring node 1
[*] Configuring node 2 as block maker and voter
[*] Configuring node 3
[*] Configuring node 4 as voter
[*] Configuring node 5 as voter
[*] Configuring node 6
[*] Configuring node 7
Transitioning towards developers, if you'd like to play around with creating Ethereum contracts, you
almost certainly would like to do that without any real money involved until you get the hang of the
entire system. In other words, instead of attaching to the main network, you want to join the **test**
network with your node, which is fully equivalent to the main network, but with play-Ether only.
```
$ geth --testnet --fast --cache=512 console
$ ./start.sh
[*] Starting Constellation nodes
[*] Starting bootnode... waiting... done
[*] Starting node 1
[*] Starting node 2
[*] Starting node 3
[*] Starting node 4
[*] Starting node 5
[*] Starting node 6
[*] Starting node 7
[*] Unlocking account and sending first transaction
Contract transaction send: TransactionHash: 0xbfb7bfb97ba9bacbf768e67ac8ef05e4ac6960fc1eeb6ab38247db91448b8ec6 waiting to be mined...
true
```
The `--fast`, `--cache` flags and `console` subcommand have the exact same meaning as above and they
are equally useful on the testnet too. Please see above for their explanations if you've skipped to
here.
We now have a 7-node Quorum cluster with a [private smart contract](https://github.com/jpmorganchase/quorum-examples/blob/master/examples/7nodes/script1.js) (SimpleStorage) sent from `node 1` "for" `node 7` (denoted by the public key passed via `privateFor: ["ROAZBWtSacxXQrOe3FGAqJDyJjFePR5ce4TSIzmJ0Bc="]` in the `sendTransaction` call).
Specifying the `--testnet` flag however will reconfigure your Geth instance a bit:
Connect to any of the nodes and inspect them using the following commands:
* Instead of using the default data directory (`~/.ethereum` on Linux for example), Geth will nest
itself one level deeper into a `testnet` subfolder (`~/.ethereum/testnet` on Linux). Note, on OSX
and Linux this also means that attaching to a running testnet node requires the use of a custom
endpoint since `geth attach` will try to attach to a production node endpoint by default. E.g.
`geth attach <datadir>/testnet/geth.ipc`. Windows users are not affected by this.
* Instead of connecting the main Ethereum network, the client will connect to the test network,
which uses different P2P bootnodes, different network IDs and genesis states.
*Note: Although there are some internal protective measures to prevent transactions from crossing
over between the main network and test network, you should make sure to always use separate accounts
for play-money and real-money. Unless you manually move accounts, Geth will by default correctly
separate the two networks and will not make any accounts available between them.*
```sh
$ geth attach ipc:qdata/dd1/geth.ipc
$ geth attach ipc:qdata/dd2/geth.ipc
...
$ geth attach ipc:qdata/dd7/geth.ipc
### Configuration
As an alternative to passing the numerous flags to the `geth` binary, you can also pass a configuration file via:
# e.g.
```
$ geth --config /path/to/your_config.toml
```
$ geth attach ipc:qdata/dd2/geth.ipc
Welcome to the Geth JavaScript console!
To get an idea how the file should look like you can use the `dumpconfig` subcommand to export your existing configuration:
instance: Geth/v1.5.0-unstable/linux/go1.7.3
coinbase: 0xca843569e3427144cead5e4d5999a3d0ccf92b8e
at block: 679 (Tue, 15 Nov 2016 00:01:05 UTC)
datadir: /home/ubuntu/quorum-examples/7nodes/qdata/dd2
modules: admin:1.0 debug:1.0 eth:1.0 net:1.0 personal:1.0 quorum:1.0 rpc:1.0 txpool:1.0 web3:1.0
```
$ geth --your-favourite-flags dumpconfig
```
*Note: This works only with geth v1.6.0 and above.*
#### Docker quick start
One of the quickest ways to get Ethereum up and running on your machine is by using Docker:
```
docker run -d --name ethereum-node -v /Users/alice/ethereum:/root \
-p 8545:8545 -p 30303:30303 \
ethereum/client-go --fast --cache=512
```
This will start geth in fast sync mode with a DB memory allowance of 512MB just as the above command does. It will also create a persistent volume in your home directory for saving your blockchain as well as map the default ports. There is also an `alpine` tag available for a slim version of the image.
### Programatically interfacing Geth nodes
As a developer, sooner rather than later you'll want to start interacting with Geth and the Ethereum
network via your own programs and not manually through the console. To aid this, Geth has built in
support for a JSON-RPC based APIs ([standard APIs](https://github.com/ethereum/wiki/wiki/JSON-RPC) and
[Geth specific APIs](https://github.com/ethereum/go-ethereum/wiki/Management-APIs)). These can be
exposed via HTTP, WebSockets and IPC (unix sockets on unix based platforms, and named pipes on Windows).
The IPC interface is enabled by default and exposes all the APIs supported by Geth, whereas the HTTP
and WS interfaces need to manually be enabled and only expose a subset of APIs due to security reasons.
These can be turned on/off and configured as you'd expect.
HTTP based JSON-RPC API options:
* `--rpc` Enable the HTTP-RPC server
* `--rpcaddr` HTTP-RPC server listening interface (default: "localhost")
* `--rpcport` HTTP-RPC server listening port (default: 8545)
* `--rpcapi` API's offered over the HTTP-RPC interface (default: "eth,net,web3")
* `--rpccorsdomain` Comma separated list of domains from which to accept cross origin requests (browser enforced)
* `--ws` Enable the WS-RPC server
* `--wsaddr` WS-RPC server listening interface (default: "localhost")
* `--wsport` WS-RPC server listening port (default: 8546)
* `--wsapi` API's offered over the WS-RPC interface (default: "eth,net,web3")
* `--wsorigins` Origins from which to accept websockets requests
* `--ipcdisable` Disable the IPC-RPC server
* `--ipcapi` API's offered over the IPC-RPC interface (default: "admin,debug,eth,miner,net,personal,shh,txpool,web3")
* `--ipcpath` Filename for IPC socket/pipe within the datadir (explicit paths escape it)
You'll need to use your own programming environments' capabilities (libraries, tools, etc) to connect
via HTTP, WS or IPC to a Geth node configured with the above flags and you'll need to speak [JSON-RPC](http://www.jsonrpc.org/specification)
on all transports. You can reuse the same connection for multiple requests!
**Note: Please understand the security implications of opening up an HTTP/WS based transport before
doing so! Hackers on the internet are actively trying to subvert Ethereum nodes with exposed APIs!
Further, all browser tabs can access locally running webservers, so malicious webpages could try to
subvert locally available APIs!**
### Operating a private network
Maintaining your own private network is more involved as a lot of configurations taken for granted in
the official networks need to be manually set up.
#### Defining the private genesis state
First, you'll need to create the genesis state of your networks, which all nodes need to be aware of
and agree upon. This consists of a small JSON file (e.g. call it `genesis.json`):
```json
> quorum.nodeInfo
{
"config": {
"chainId": 0,
"homesteadBlock": 0,
"eip155Block": 0,
"eip158Block": 0
},
"alloc" : {},
"coinbase" : "0x0000000000000000000000000000000000000000",
"difficulty" : "0x20000",
"extraData" : "",
"gasLimit" : "0x2fefd8",
"nonce" : "0x0000000000000042",
"mixhash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
"parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
"timestamp" : "0x00"
blockMakerAccount: "0xca843569e3427144cead5e4d5999a3d0ccf92b8e",
blockmakestrategy: {
maxblocktime: 10,
minblocktime: 3,
status: "active",
type: "deadline"
},
canCreateBlocks: true,
canVote: true,
voteAccount: "0x0fbdc686b912d7722dc86510934589e0aaf3b55a"
}
# let's look at the private txn created earlier:
> eth.getTransaction("0xbfb7bfb97ba9bacbf768e67ac8ef05e4ac6960fc1eeb6ab38247db91448b8ec6")
{
blockHash: "0xb6aec633ef1f79daddc071bec8a56b7099ab08ac9ff2dc2764ffb34d5a8d15f8",
blockNumber: 1,
from: "0xed9d02e382b34818e88b88a309c7fe71e65f419d",
gas: 300000,
gasPrice: 0,
hash: "0xbfb7bfb97ba9bacbf768e67ac8ef05e4ac6960fc1eeb6ab38247db91448b8ec6",
input: "0x9820c1a5869713757565daede6fcec57f3a6b45d659e59e72c98c531dcba9ed206fd0012c75ce72dc8b48cd079ac08536d3214b1a4043da8cea85be858b39c1d",
nonce: 0,
r: "0x226615349dc143a26852d91d2dff1e57b4259b576f675b06173e9972850089e7",
s: "0x45d74765c5400c5c280dd6285a84032bdcb1de85a846e87b57e9e0cedad6c427",
to: null,
transactionIndex: 1,
v: "0x25",
value: 0
}
```
The above fields should be fine for most purposes, although we'd recommend changing the `nonce` to
some random value so you prevent unknown remote nodes from being able to connect to you. If you'd
like to pre-fund some accounts for easier testing, you can populate the `alloc` field with account
configs:
Note in particular the `v` field of "0x25" (37 in decimal) which marks this transaction as having a private payload (input).
```json
"alloc": {
"0x0000000000000000000000000000000000000001": {"balance": "111111111"},
"0x0000000000000000000000000000000000000002": {"balance": "222222222"}
}
```
## Demonstrating Privacy
Documentation detailing steps to demonstrate the privacy features of Quorum can be found in [quorum-examples/7nodes/README](https://github.com/jpmorganchase/quorum-examples/tree/master/examples/7nodes/README.md).
With the genesis state defined in the above JSON file, you'll need to initialize **every** Geth node
with it prior to starting it up to ensure all blockchain parameters are correctly set:
## Further Reading
```
$ geth init path/to/genesis.json
```
Further documentation can be found in the [docs](docs/) folder and on the [wiki](https://github.com/jpmorganchase/quorum/wiki/).
#### Creating the rendezvous point
## See also
With all nodes that you want to run initialized to the desired genesis state, you'll need to start a
bootstrap node that others can use to find each other in your network and/or over the internet. The
clean way is to configure and run a dedicated bootnode:
* [Quorum](https://github.com/jpmorganchase/quorum): this repository
* [Constellation](https://github.com/jpmorganchase/constellation): peer-to-peer encrypted message exchange for transaction privacy
* [Raft Consensus Documentation](raft/doc.md)
* [quorum-examples](https://github.com/jpmorganchase/quorum-examples): example quorum clusters
* [Quorum Wiki](https://github.com/jpmorganchase/quorum/wiki)
```
$ bootnode --genkey=boot.key
$ bootnode --nodekey=boot.key
```
## Third Party Tools/Libraries
With the bootnode online, it will display an [`enode` URL](https://github.com/ethereum/wiki/wiki/enode-url-format)
that other nodes can use to connect to it and exchange peer information. Make sure to replace the
displayed IP address information (most probably `[::]`) with your externally accessible IP to get the
actual `enode` URL.
The following Quorum-related libraries/applications have been created by Third Parties and as such are not specifically endorsed by J.P. Morgan. A big thanks to the developers for improving the tooling around Quorum!
*Note: You could also use a full fledged Geth node as a bootnode, but it's the less recommended way.*
* [Quorum-Genesis](https://github.com/davebryson/quorum-genesis) - A simple CL utility for Quorum to help populate the genesis file with voters and makers
* [QuorumNetworkManager](https://github.com/ConsenSys/QuorumNetworkManager) - makes creating & managing Quorum networks easy
* [web3j-quorum](https://github.com/web3j/quorum) - an extension to the web3j Java library providing support for the Quorum API
* [Nethereum Quorum](https://github.com/Nethereum/Nethereum/tree/master/src/Nethereum.Quorum) - a .net Quorum adapter
#### Starting up your member nodes
## Contributing
With the bootnode operational and externally reachable (you can try `telnet <ip> <port>` to ensure
it's indeed reachable), start every subsequent Geth node pointed to the bootnode for peer discovery
via the `--bootnodes` flag. It will probably also be desirable to keep the data directory of your
private network separated, so do also specify a custom `--datadir` flag.
Thank you for your interest in contributing to Quorum!
```
$ geth --datadir=path/to/custom/data/folder --bootnodes=<bootnode-enode-url-from-above>
```
*Note: Since your network will be completely cut off from the main and test networks, you'll also
need to configure a miner to process transactions and create new blocks for you.*
#### Running a private miner
Mining on the public Ethereum network is a complex task as it's only feasible using GPUs, requiring
an OpenCL or CUDA enabled `ethminer` instance. For information on such a setup, please consult the
[EtherMining subreddit](https://www.reddit.com/r/EtherMining/) and the [Genoil miner](https://github.com/Genoil/cpp-ethereum)
repository.
In a private network setting however, a single CPU miner instance is more than enough for practical
purposes as it can produce a stable stream of blocks at the correct intervals without needing heavy
resources (consider running on a single thread, no need for multiple ones either). To start a Geth
instance for mining, run it with all your usual flags, extended by:
```
$ geth <usual-flags> --mine --minerthreads=1 --etherbase=0x0000000000000000000000000000000000000000
```
Which will start mining bocks and transactions on a single CPU thread, crediting all proceedings to
the account specified by `--etherbase`. You can further tune the mining by changing the default gas
limit blocks converge to (`--targetgaslimit`) and the price transactions are accepted at (`--gasprice`).

# API
## Privacy APIs
### `web3.eth.sendTransaction(object)` was modified to support private transactions
```js
web3.eth.sendTransaction(transactionObject [, callback])
```
Sends a transaction to the network.
##### Parameters
1. `Object` - The transaction object to send:
- `from`: `String` - The address for the sending account. Uses the [web3.eth.defaultAccount](#web3ethdefaultaccount) property, if not specified.
- `to`: `String` - (optional) The destination address of the message, left undefined for a contract-creation transaction.
- `value`: `Number|String|BigNumber` - (optional) The value transferred for the transaction in Wei, also the endowment if it's a contract-creation transaction.
- `gas`: `Number|String|BigNumber` - (optional, default: To-Be-Determined) The amount of gas to use for the transaction (unused gas is refunded).
- <strike>`gasPrice`: `Number|String|BigNumber` - (optional, default: To-Be-Determined) The price of gas for this transaction in wei, defaults to the mean network gas price.</strike>
- `data`: `String` - (optional) Either a [byte string](https://github.com/ethereum/wiki/wiki/Solidity,-Docs-and-ABI) containing the associated data of the message, or in the case of a contract-creation transaction, the initialisation code.
- `nonce`: `Number` - (optional) Integer of a nonce. This allows to overwrite your own pending transactions that use the same nonce.
- `privateFrom`: `String` - (optional) When sending a private transaction, the sending party's base64-encoded public key to use. If not present *and* passing `privateFor`, use the default key as configured in the `TransactionManager`.
- `privateFor`: `List<String>` - (optional) When sending a private transaction, an array of the recipients' base64-encoded public keys.
2. `Function` - (optional) If you pass a callback the HTTP request is made asynchronous. See [this note](#using-callbacks) for details.
##### Returns
`String` - The 32 Bytes transaction hash as HEX string.
If the transaction was a contract creation use [web3.eth.getTransactionReceipt()](#web3gettransactionreceipt) to get the contract address, after the transaction was mined.
##### Example
```js
// compiled solidity source code using https://chriseth.github.io/cpp-ethereum/
var code = "603d80600c6000396000f3007c01000000000000000000000000000000000000000000000000000000006000350463c6888fa18114602d57005b6007600435028060005260206000f3";
web3.eth.sendTransaction({
data: code,
privateFor: ["ROAZBWtSacxXQrOe3FGAqJDyJjFePR5ce4TSIzmJ0Bc="]
},
function(err, address) {
if (!err) {
console.log(address); // "0x7f9fade1c0d57a7af66ab4ead7c2eb7b11a91385"
}
}
});
```
## QuorumChain APIs
Quorum provides an API to inspect the current state of the voting contract.
### `quorum.nodeInfo` returns the quorum capabilities of this node
Example output for a node that is configured as block maker and voter:
```
> quorum.nodeInfo
{
blockMakerAccount: "0xed9d02e382b34818e88b88a309c7fe71e65f419d",
blockmakestrategy: {
maxblocktime: 6,
minblocktime: 3,
status: "active",
type: "deadline"
},
canCreateBlocks: true,
canVote: true,
voteAccount: "0xed9d02e382b34818e88b88a309c7fe71e65f419d"
}
```
### `quorum.vote` votes for the given hash to be the canonical head on the current height and returns the tx hash
```
> quorum.vote(eth.getBlock("latest").hash)
"0x16c69b9bdf9f10c64e65dbfe50bc997d2bc1ed321c6041db602908b7f6cab2a9"
```
### `quorum.canonicalHash` returns the canonical hash for the given block height (add 1 for the hash that the current pending block will be based on top of)
```
> quorum.canonicalHash(eth.blockNumber+1)
"0xf2c8a36d0c54c7013246fddebfc29bc881f6f10f74f761d511b5ebfaa103adfa"
```
### `quorum.isVoter` returns whether the given address is allowed to vote for new blocks
```
> quorum.isVoter("0xed9d02e382b34818e88b88a309c7fe71e65f419d")
true
```
### `quorum.isBlockMaker` returns whether the given address is allowed to make blocks
```
> quorum.isBlockMaker("0xed9d02e382b34818e88b88a309c7fe71e65f419d")
true
```
### `quorum.makeBlock` orders the node to create a block bypassing block maker strategy
```
> quorum.makeBlock()
"0x3a07e82a48ab3c19a3d09d247e189e3a3041d1d9eafd2e1515b4ddd5b016bfd9"
```
### `quorum.pauseBlockMaker` (temporary) orders the node to stop creating blocks
```
> quorum.pauseBlockMaker()
null
> quorum.nodeInfo
{
blockMakerAccount: "0xed9d02e382b34818e88b88a309c7fe71e65f419d",
blockmakestrategy: {
maxblocktime: 6,
minblocktime: 3,
status: "paused",
type: "deadline"
},
canCreateBlocks: true,
canVote: true,
voteAccount: "0xed9d02e382b34818e88b88a309c7fe71e65f419d"
}
```
### `quorum.resumeBlockMaker` instructs a paused node to begin creating blocks again
```
> quorum.resumeBlockMaker()
null
> quorum.nodeInfo
{
blockMakerAccount: "0xed9d02e382b34818e88b88a309c7fe71e65f419d",
blockmakestrategy: {
maxblocktime: 6,
minblocktime: 3,
status: "active",
type: "deadline"
},
canCreateBlocks: true,
canVote: true,
voteAccount: "0xed9d02e382b34818e88b88a309c7fe71e65f419d"
}
```

# Design
## Consensus algorithm
Quorum introduces a new consensus algorithm called QuorumChain, a majority
voting protocol where a subset of nodes within the network are given the
`voting` role. The voting role allows a node to vote on which block should be the
canonical head at a particular height. The block with the most votes will win
and is considered the canonical head of the chain.
Block creation is only allowed by nodes with the `block maker` role.
A node with this role can create a block, sign the block and put the signature within the `ExtraData` field of the block.
On `block import`, nodes can verify if the block was signed by one of the nodes that have the `block maker` role.
Nodes can be given no role, one of the roles or both roles through command line arguments.
The collection of addresses with special roles is tracked within the Quorum smart contract.
QuorumChain is implemented in a smart contract pre-deployed on address `0x0000000000000000000000000000000000000020` and can be found [here](https://github.com/jpmorganchase/quorum/blob/master/core/quorum/block_voting.sol).
Voters and block makers can be added or removed and the minimum number of votes before a block is selected as winner can be configured.
## Public/Private State
Quorum supports dual state:
- public state, accessible by all nodes within the network
- private state, only accessible by nodes with the correct permissions
The difference is made through the use of transactions with encrypted (private) and non-encrypted payloads (public).
Nodes can determine if a transaction is private by looking at the `v` value of the signature.
Public transactions have a `v` value of 27 or 28, private transactions have a value of 37 or 38.
If the transaction is private and the node has the ability to decrypt the payload it can execute the transaction.
Nodes who are not involved in the transaction cannot decrypt the payload and process the transaction.
As a result all nodes share a common public state which is created through public transactions and have a local unique private state.
This model imposes a restriction in the ability to modify state in private transactions.
Since its a common use case that a (private) contract reads data from a public contract the virtual machine has the ability to jump into read only mode.
For each call from a private contract to a public contract the virtual machine will change to read only mode.
If the virtual machine is in read only mode and the code tries to make a state change the virtual machine stops execution and throws an exception.
The following transactions are allowed:
S: sender, (X): private, X: public, ->: direction, []: read only mode
```
1. S -> A -> B
2. S -> (A) -> (B)
3. S -> (A) -> [B -> C]
```
The following transaction are unsupported:
```
1. (S) -> A
2. (S) -> (A)
```
### State verification
To determine if nodes are in sync the public state root hash is included in the block.
Since private transactions can only be processed by nodes that are involved its impossible to get global consensus on the private state.
To overcome this issue the RPC method `eth_storageRoot(address[, blockNumber]) -> hash` can be used.
It returns the storage root for the given address at an (optional) block number.
If the optional block number is not given the latest block number is used.
The storage root hash can be on or off chain compared by the parties involved.

# Privacy
## Sending Private Transactions
To send a private transaction, a `PrivateTransactionManager` must be configured. This is the
service which transfers private payloads to their intended recipients, performing
encryption and related operations in the process.
Currently, `constellation` is supported out of the box via the `PRIVATE_CONFIG` environment
variable (please note that this integration method will change in the near future.) See the
`7nodes` folder in the `quorum-examples` repository for a complete example of how to use it.
The transaction sent in `script1.js` is private for node 7's `PrivateTransactionManager`
public key.
Once `constellation` is launched and `PRIVATE_CONFIG` points to a valid configuration file,
a `SendTransaction` call can be made private by specifying the `privateFor` argument.
`privateFor` is a list of public keys of the intended recipients. (Note that in the case of
`constellation`, this public key is distinct from Ethereum account keys.) When a transaction
is private, the transaction contents will be sent to the `PrivateTransactionManager` and the
identifier returned will be placed in the transaction instead. When other Quorum nodes
receive a private transaction, they will query their `PrivateTransactionManager` for the
identifier and replace the transaction contents with the result (if any; nodes which are
not party to a transaction will not be able to retrieve the original contents.)

# Running Quorum
The following new CLI arguments were introduced as part of Quorum:
```
QUORUM OPTIONS:
--voteaccount value Address that is used to vote for blocks
--votepassword value Password to unlock the voting address
--blockmakeraccount value Address that is used to create blocks
--blockmakerpassword value Password to unlock the block maker address
--singleblockmaker Indicate this node is the only node that can create blocks
--minblocktime value Set minimum block time (default: 3)
--maxblocktime value Set max block time (default: 10)
--permissioned If enabled, the node will allow only a defined list of nodes to connect
```
The full list of arguments can be viewed by running `geth --help`.
### Initialize chain
The first step is to generate the genesis block.
The genesis block should include the Quorum voting contract address `0x0000000000000000000000000000000000000020`.
The code can be generated with [browser solidity](http://ethereum.github.io/browser-solidity/#version=soljson-latest.js) (note, use the runtime code) or using the solidity compiler: `solc --optimize --bin-runtime block_voting.sol`.
The `7nodes` directory in the `quorum-examples` repository contains several keys (using an empty password) that are used in the example genesis file:
```
key1 vote key 1
key2 vote key 2
key3 vote key 3
key4 block maker 1
key5 block maker 2
```
Example genesis file (copy to `genesis.json`):
```json
{

Now we can initialize geth:
```
geth init genesis.json
```
The storage key for voters and block makers is calculated with `web3.sha3(<256 bit aligned key value> + <256 bit variable index>)`.
The console can be used to calculate the storage key, in this case for vote key 1:
```
> key = "000000000000000000000000ed9d02e382b34818e88b88a309c7fe71e65f419d" + "0000000000000000000000000000000000000000000000000000000000000003"
"000000000000000000000000ed9d02e382b34818e88b88a309c7fe71e65f419d0000000000000000000000000000000000000000000000000000000000000003"
> web3.sha3(key, {"encoding": "hex"})
"0x29ecdbdf95c7f6ceec92d6150c697aa14abeb0f8595dd58d808842ea237d8494"
```
From the above example, the `<256 bit aligned key value>` is the ethereum account address that should be added to the voting map, ed9d02e382b34818e88b88a309c7fe71e65f419d, padded to 256bits. The `<256 bit variable index>` is the index(3) of the canVote mapping in the solidity [voting smart contract](https://github.com/jpmorganchase/quorum/blob/master/core/quorum/block_voting.sol#L42) padded to 256bits. The index is calculated based on the location of canVote:
* Period[] periods --> index 0
* uint public voteThreshold --> index 1
* uint public voterCount --> index 2
* mapping(address => bool) public canVote --> index 3
The `genesis.json` file can be found in the `7nodes` folder in the `quorum-examples` repository.
### Setup Bootnode
Optionally you can set up a bootnode that all the other nodes will first connect to in order to find other peers in the network. You will first need to generate a bootnode key:
1- To generate the key for the first time:
`bootnode –genkey tmp_file.txt //this will start a bootnode with an enode address and generate a key inside a “tmp_file.txt” file`
2- To later restart the bootnode using the same key (and hence use the same enode url):
`bootnode –nodekey tmp_file.txt`
or
`bootnode –nodekeyhex 77bd02ffa26e3fb8f324bda24ae588066f1873d95680104de5bc2db9e7b2e510 // Key from tmp_file.txt`
### Start node
Starting a node is as simple as `geth`. This will start the node without any of the roles and makes the node a spectator. If you have setup a bootnode then be sure to add the `--bootnodes` param to your startup command:
`geth --bootnodes $BOOTNODE_ENODE`
### Voting role
Start a node with the voting role:
```
geth --voteaccount 0xed9d02e382b34818e88b88a309c7fe71e65f419d
```
Optionally the `--votepassword` can be used to unlock the account.
If this flag is omitted the node will prompt for the password.
### Block maker role
Start a node with the block maker role:
```
geth --blockmakeraccount 0x9186eb3d20cbd1f5f992a950d808c4495153abd5
```
Created blocks will be signed with this account.
Optionally the `--blockmakerpassword` can be used to unlock the account.
If this flag is omitted the node will prompt for the password.
## Setup multi-node network
Quorum comes with several scripts to setup a private test network with 7 nodes:
* node 1, has no special roles
* node 2, has the block maker role
* node 3, has no special roles
* node 4, has the voting role
* node 5, has the voting role
* node 6, has no special roles
All scripts can be found in the `7nodes` folder in the `quorum-examples` repository.
1. Step 1, run `init.sh` and initialize data directories (change variables accordingly)
2. Step 2, start nodes with `start.sh` (change variables accordingly)
3. Step 3, stop network with `stop.sh`
## Permissioned Network
Node Permissioning is a feature that controls which nodes can connect to a given node and also to which nodes this node can dial out to. Currently, it is managed at individual node level by the command line flag `--permissioned` while starting the node.
If the `--permissioned` node is present, the node looks for a file named `<data-dir>/permissioned-nodes.json`. This file contains the list of enodes that this node can connect to and also accepts connections only from those nodes. In other words, if permissioning is enabled, only the nodes that are listed in this file become part of the network. It is an error to enable `--permissioned` but not have the `permissioned-nodes.json` file. If the flag is given, but no nodes are present in this file, then this node can neither connect to any node or accept any incoming connections.
The `permissioned-nodes.json` follows following pattern (similar to `static-nodes.json`):
```json
[
"enode://enodehash1@ip1:port1",
"enode://enodehash2@ip2:port2",
"enode://enodehash3@ip3:port3",
]
```
Sample file:
```json
[
"enode://6598638ac5b15ee386210156a43f565fa8c48592489d3e66ac774eac759db9eb52866898cf0c5e597a1595d9e60e1a19c84f77df489324e2f3a967207c047470@127.0.0.1:30300",
]
```
In the current release, every node has its own copy of `permissioned-nodes.json`. In a future release, the permissioned nodes list will be moved to a smart contract, thereby keeping the list on chain and one global list of nodes that connect to the network.
