EOS.IO - The Most Powerful Infrastructure for Decentralized Applications

Build Status

Welcome to the EOS.IO source code repository! EOS.IO software enables developers to create and deploy high-performance, horizontally scalable, blockchain infrastructure upon which decentralized applications can be built.

This code is currently alpha-quality and under rapid development. That said, there is plenty early experimenters can do including running a private multi-node test network and developing applications (smart contracts).

The public testnet described in the wiki is running the dawn-2.x branch. The master branch is no longer compatible with the public testnet. Instructions are provided below for building a local testnet using the master branch. This document will be updated later with instructions for running on the dawn-3.x public testnet.

Supported Operating Systems

EOS.IO currently supports the following operating systems:

  1. Amazon 2017.09 and higher.
  2. Centos 7.
  3. Fedora 25 and higher (Fedora 27 recommended).
  4. Mint 18.
  5. Ubuntu 16.04 (Ubuntu 16.10 recommended).
  6. MacOS Darwin 10.12 and higher (MacOS 10.13.x recommended).

Getting Started

The following instructions detail the process of getting the software, building it, running a simple test network that produces blocks, account creation and uploading a sample contract to the blockchain.

Setting up a build/development environment

Getting the code

To download all of the code, clone the eos repository and its submodules.

git clone https://github.com/eosio/eos --recursive

If a repo is cloned without the --recursive flag, the submodules can be retrieved after the fact by running this command from within the repo:

git submodule update --init --recursive

Building the executables

EOS comes with a number of programs:

  • nodeos - server-side blockchain node component
  • cleos - command line interface to interact with the blockchain
  • keosd - EOS wallet
  • eosio-launcher - application for nodes network composing and deployment; more on eosio-launcher

The build places content in the eos/build folder. The executables can be found in subfolders within the eos/build/programs folder.

Automated build script

There is an automated build script that can install all dependencies and build EOS. We are working on supporting other Linux/Unix distributions in future releases.

Run the build script.

cd eos
./eosio_build.sh

Manual build

To manually build, use the following steps to create a build folder within your eos folder and then perform the build. The steps below assume the eos repository was cloned into your home (i.e., ~) folder.

cd ~
mkdir -p ~/eos/build && cd ~/eos/build
cmake -DBINARYEN_BIN=~/binaryen/bin -DWASM_ROOT=~/wasm-compiler/llvm -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl -DOPENSSL_LIBRARIES=/usr/local/opt/openssl/lib ..
make -j$( nproc )

Out-of-source builds are also supported. To override clang's default choice in compiler, add these flags to the CMake command:

-DCMAKE_CXX_COMPILER=/path/to/c++ -DCMAKE_C_COMPILER=/path/to/cc

For a debug build, add -DCMAKE_BUILD_TYPE=Debug. Other common build types include Release and RelWithDebInfo.

To run the test suite after building, run the chain_test executable in the tests folder.

Build validation

Optionally, a set of tests can be run against your build to perform some basic validation.

cd build
make test

Install the executables

For ease of contract development, content can be installed in the /usr/local folder using the make install target. This step is run from the build folder. Adequate permission is required to install.

cd build
sudo make install

Running a node

Running a single-node testnet

After successfully building the project, the nodeos binary should be present in the build/programs/nodeos folder. nodeos can be run directly from the build folder using programs/nodeos/nodeos.

nodeos uses a custom configuration folder. The location of this folder is determined by your system.

  • Mac OS: ~/Library/Application Support/eosio/nodeos/config
  • Linux: ~/.local/share/eosio/nodeos/config

The build seeds this folder with a default genesis.json file. Alternatively, a configuration folder can be specified using the --config-dir command line argument to nodeos. If you use this option, you will need to manually copy a genesis.json file to your config folder.

nodeos will need a properly configured config.ini file in order to do meaningful work. On startup, nodeos looks in the config folder for config.ini. If one is not found, a default config.ini file is created. If you do not already have a config.ini file ready to use, run nodeos and then close it immediately with Ctrl-C. A default configuration (config.ini) will have been created in the config folder. Edit the config.ini file, adding/updating the following settings to the defaults already in place:

# Load the testnet genesis state, which creates some initial block producers with the default key
genesis-json = /path/to/eos/source/genesis.json
 # Enable production on a stale chain, since a single-node test chain is pretty much always stale
enable-stale-production = true
# Enable block production with the testnet producers
producer-name = eosio
# Load the block producer plugin, so you can produce blocks
plugin = eosio::producer_plugin
# Wallet plugin
plugin = eosio::wallet_api_plugin
# As well as API and HTTP plugins
plugin = eosio::chain_api_plugin
plugin = eosio::http_plugin

Now it should be possible to run nodeos and see it begin producing blocks.

When running nodeos you should get log messages similar to below. It means the blocks are successfully produced.

1575001ms thread-0   chain_controller.cpp:235      _push_block          ] initm #1 @2017-09-04T04:26:15  | 0 trx, 0 pending, exectime_ms=0
1575001ms thread-0   producer_plugin.cpp:207       block_production_loo ] initm generated block #1 @ 2017-09-04T04:26:15 with 0 trxs  0 pending
1578001ms thread-0   chain_controller.cpp:235      _push_block          ] initc #2 @2017-09-04T04:26:18  | 0 trx, 0 pending, exectime_ms=0
1578001ms thread-0   producer_plugin.cpp:207       block_production_loo ] initc generated block #2 @ 2017-09-04T04:26:18 with 0 trxs  0 pending
...

nodeos stores runtime data (e.g., shared memory and log content) in a custom data folder. The location of this folder is determined by your system.

  • Mac OS: ~/Library/Application Support/eosio/nodeos/data
  • Linux: ~/.local/share/eosio/nodeos/data

A data folder can be specified using the --data-dir command line argument to nodeos.

Running a multi-node local testnet

To run a local testnet you can use the eosio-launcher application provided in the ~/eos/build/programs/eosio-launcher folder.

For testing purposes you will run two local production nodes talking to each other.

cd ~/eos/build
cp ../genesis.json ./
./programs/eosio-launcher/eosio-launcher -p2 --skip-signature

This command will generate two data folders for each instance of the node: tn_data_00 and tn_data_01.

You should see the following response:

spawning child, programs/nodeos/nodeos --skip-transaction-signatures --data-dir tn_data_0
spawning child, programs/nodeos/nodeos --skip-transaction-signatures --data-dir tn_data_1

To confirm the nodes are running, run the following cleos commands:

~/eos/build/programs/cleos
./cleos -p 8888 get info
./cleos -p 8889 get info

For each command, you should get a JSON response with blockchain information.

You can read more on eosio-launcher and its settings here

Running a local node connected to the public testnet

The master branch is no longer compatible with the dawn-2.x public testnet. To run on the public testnet, please see dawn-2.x/eos/README.md

Next Steps

Further documentation is available in the wiki. Wiki pages include detailed reference documentation for all programs and tools and the database schema and API. The wiki also includes a section describing smart contract development. A simple walkthrough of the "currency" contract follows.

Example "Currency" Contract Walkthrough

EOS comes with example contracts that can be uploaded and run for testing purposes. Next we demonstrate how to upload and interact with the sample contract "currency".

Example smart contracts

First, run the node

cd ~/eos/build/programs/nodeos/
./nodeos

Setting up a wallet and importing account key

As you've previously added plugin = eosio::wallet_api_plugin into config.ini, EOS wallet will be running as a part of nodeos process. Every contract requires an associated account, so first, create a wallet.

cd ~/eos/build/programs/cleos/
./cleos wallet create # Outputs a password that you need to save to be able to lock/unlock the wallet

For the purpose of this walkthrough, import the private key of the eosio account, a system account included within genesis.json, so that you're able to issue API commands under authority of an existing account. The private key referenced below is found within your config.ini and is provided to you for testing purposes.

./cleos wallet import 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3

Creating accounts for sample "currency" contract

First, generate some public/private key pairs that will be later assigned as owner_key and active_key.

cd ~/eos/build/programs/cleos/
./cleos create key # owner_key
./cleos create key # active_key

This will output two pairs of public and private keys

Private key: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
Public key: EOSXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

Important: Save the values for future reference.

Run the create command where eosio is the account authorizing the creation of the currency account and PUBLIC_KEY_1 and PUBLIC_KEY_2 are the values generated by the create key command

./cleos create account eosio currency PUBLIC_KEY_1 PUBLIC_KEY_2

You should then get a JSON response back with a transaction ID confirming it was executed successfully.

Go ahead and check that the account was successfully created

./cleos get account currency

If all went well, you will receive output similar to the following:

{
  "account_name": "currency",
  "eos_balance": "0.0000 EOS",
  "staked_balance": "0.0001 EOS",
  "unstaking_balance": "0.0000 EOS",
  "last_unstaking_time": "2035-10-29T06:32:22",
   ...
}

Now import the active private key generated previously in the wallet:

./cleos wallet import XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

Upload sample "currency" contract to blockchain

Before uploading a contract, verify that there is no current contract:

./cleos get code currency
code hash: 0000000000000000000000000000000000000000000000000000000000000000

With an account for a contract created, upload a sample contract:

./cleos set contract currency ../../contracts/currency/currency.wast ../../contracts/currency/currency.abi

As a response you should get a JSON with a transaction_id field. Your contract was successfully uploaded!

You can also verify that the code has been set with the following command:

./cleos get code currency

It will return something like:

code hash: 9b9db1a7940503a88535517049e64467a6e8f4e9e03af15e9968ec89dd794975

Before using the currency contract, you must issue the currency.

./cleos push action currency issue '{"to":"currency","quantity":"1000.0000 CUR","memo":""}' --permission currency@active

Next verify the currency contract has the proper initial balance:

./cleos get table currency currency account
{
  "rows": [{
     "currency": 1381319428,
     "balance": 10000000
     }
  ],
  "more": false
}

Transfering funds with the sample "currency" contract

Anyone can send any message to any contract at any time, but the contracts may reject messages which are not given necessary permission. Messages are not sent "from" anyone, they are sent "with permission of" one or more accounts and permission levels. The following commands show a "transfer" message being sent to the "currency" contract.

The content of the message is '{"from":"currency","to":"eosio","quantity":"20.0000 CUR","memo":"any string"}'. In this case we are asking the currency contract to transfer funds from itself to someone else. This requires the permission of the currency contract.

./cleos push action currency transfer '{"from":"currency","to":"eosio","quantity":"20.0000 CUR","memo":"my first transfer"}' --permission currency@active

Below is a generalization that shows the currency account is only referenced once, to specify which contract to deliver the transfer message to.

./cleos push action currency transfer '{"from":"${usera}","to":"${userb}","quantity":"20.0000 CUR","memo":""}' --permission ${usera}@active

As confirmation of a successfully submitted transaction, you will receive JSON output that includes a transaction_id field.

Reading sample "currency" contract balance

So now check the state of both of the accounts involved in the previous transaction.

./cleos get table eosio currency account
{
  "rows": [{
      "currency": 1381319428,
      "balance": 200000
       }
    ],
  "more": false
}
./cleos get table currency currency account
{
  "rows": [{
      "currency": 1381319428,
      "balance": 9800000
    }
  ],
  "more": false
}

As expected, the receiving account eosio now has a balance of 20 tokens, and the sending account now has 20 less tokens than its initial supply.

By default LLVM and clang do not include the WASM build target, so you will have to build it yourself:

mkdir  ~/wasm-compiler
cd ~/wasm-compiler
git clone --depth 1 --single-branch --branch release_40 https://github.com/llvm-mirror/llvm.git
cd llvm/tools
git clone --depth 1 --single-branch --branch release_40 https://github.com/llvm-mirror/clang.git
cd ..
mkdir build
cd build
cmake -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX=.. -DLLVM_TARGETS_TO_BUILD= -DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD=WebAssembly -DCMAKE_BUILD_TYPE=Release ../
make -j4 install

Your environment is set up. Now you can build EOS and run a node.
