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?

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 -``` - -This command will: - - * 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`. - -### Full node on the Ethereum test network - -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 +```sh +git clone https://github.com/jpmorganchase/quorum-examples +cd quorum-examples +vagrant up +# (should take 5 or so minutes) +vagrant ssh ``` -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. - -Specifying the `--testnet` flag however will reconfigure your Geth instance a bit: - - * 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 /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.* +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. -### Configuration - -As an alternative to passing the numerous flags to the `geth` binary, you can also pass a configuration file via: - -``` -$ geth --config /path/to/your_config.toml -``` +```sh +# (from within vagrant env, use `vagrant ssh` to enter) +ubuntu@ubuntu-xenial:~$ cd quorum-examples/7nodes -To get an idea how the file should look like you can use the `dumpconfig` subcommand to export your existing configuration: +$ ./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 +$ ./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 ``` -$ 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 -``` +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). -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. +Connect to any of the nodes and inspect them using the following commands: -### Programatically interfacing Geth nodes +```sh +$ geth attach ipc:qdata/dd1/geth.ipc +$ geth attach ipc:qdata/dd2/geth.ipc +... +$ geth attach ipc:qdata/dd7/geth.ipc -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.

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.

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 `/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.
