Developer Sandbox

There are three options for running a sandbox.
1.​Run only a local sandbox server​
1.Minimal setup
2.good for quickly testing APIs
3.Better feedback metrics
2.​Run a test server and client​
1.Much closer to production experience
2.Needed if multiple clients are used
3.Factom setup needed on two different computers
3.​Run a Dockerized Factom sandbox​
1.Zero setup
2.Good if you are already familiar with Docker
3.Almost the same as running a local sandbox server
Setup a Local Sandbox Factom Server
Install Factom Binaries
Download the appropriate Factom binary package from factom.org. Installers for for Windows, Mac, and Linux are hosted at https://github.com/FactomProject/distribution. Directions for installing Factom Federation may be found here.
Install the binaries like you would any other for your OS. The install directions walk you through various operating systems. Do not run them yet, as you will be making your own fresh blockchain instead of using the public one.
 If you did run factomd before setup, follow the directions found here to reset the blockchain.
Three programs are installed: factomd, factom-walletd, and factom-cli. You may also wish to install the GUI Enterprise Wallet.
Factomdis the main program. It manages the blockchain, connects to the public network, and enforces the network rules.
factom-walletd is an application for holding private keys. It builds Factoid transactions and handles crypto related operations to add user data into Factom.
Factom-cli is a program for users to interface with factomd and factom-walletd. It may be used to create Chains, Entries, and Factoid transactions.
Configure Factomd for Sandbox use
Create a folder in your user home folder. The folder should be called .factom. If factomd has been run on your computer before this folder will already exist and may already contain part of the Factom blockchain.
In a terminal on Linux or  Mac, run: 
mkdir -p ~/.factom/m2
or Windows: 
mkdir %HOMEDRIVE%%HOMEPATH%\.factom\m2
Save the configuration file factomd.conf to your .factom/m2 directory. Open factomd.conf and edit the following:
Change the line Network from MAIN to LOCAL
This will cause factomd to run on its own local network rather than the Factom main network.
Change the line NodeMode from FULL to SERVER
This will make factomd create a blockchain.
Optionally, adjust DirectoryBlockInSeconds. 600 gives 10 minute blocks, which is more realistic
The default is for 6 second blocks which is easier to develop with, but may causesome strange behavior and errors.
For easier debugging, change the logLevel to debug. This exports pointers to data which is added into Factom to the ~/.factom/data/export/ directory. Adding new entries will add new files to the directory with the specified ChainID.
Run Factomd in sandbox mode
In a terminal window, run:
factomd -network=CUSTOM -customnet="mycustomnet" -exclusive=true
In a new terminal window, run:
factom-walletd
In a new terminal window, run:
factom-cli properties
Result should be similar to:
% factom-cli properties
CLI Version: 0.2.0.2
Factomd Version: 0.4.0.2
Factomd API Version: 2.0
Wallet Version: 0.2.0.2
Wallet API Version: 2.0
Windows users have a desktop shortcut for both first and second command, for the last one you might have to browse to the install location of factom-cli, or it might be in the path.
Once factomd is running you can use an internet browser and navigate to view the factomdControl Panel, found at http://localhost:8090.
Charge an Entry Credit key
We use a Factoid key which has a balance of 40000 in the genesis block. It has since been depleted on main net, but can be used on sandbox systems. 
The private key is: Fs3E9gV6DXsYzf7Fqx1fVBQPQXV695eP3k5XbmHEZVRLkMdD9qCK 
The public key is: FA2jK2HcLnRdS94dEcU27rF3meoJfpUcZPSinpb7AwQvPRY6RL1Q
To import the address, run:
factom-cli importaddress Fs3E9gV6DXsYzf7Fqx1fVBQPQXV695eP3k5XbmHEZVRLkMdD9qCK
Now lets generate a new Entry Credit address:
factom-cli newecaddress
To verify that you've imported and generated your addresses you can list them:
factom-cli listaddresses
Result should be similar to:
FA2jK2HcLnRdS94dEcU27rF3meoJfpUcZPSinpb7AwQvPRY6RL1Q 40000
EC2kMjtY5jB5sLLzFtfzaA2rU92fqdNeiWNWjvtKmYQoG7fXFTmG 0
​
% Named the addresses fa1 and ec1
% fa1=FA2jK2HcLnRdS94dEcU27rF3meoJfpUcZPSinpb7AwQvPRY6RL1Q
% ec1=EC2kMjtY5jB5sLLzFtfzaA2rU92fqdNeiWNWjvtKmYQoG7fXFTmG
Then purchase Entry Credits using our Factoid address.
factom-cli buyec $fa1 $ec1 10000
Result:
TxID: ce18d00316508dd44a02d20bb3d9ee15f909bd9a099dd1b9b4576e2688f8f42a
Status: TransactionACK
If you want to check your EC balance run:
factom-cli balance $ec1
Make Entries into Factom
All Entries in Factom need to be in a Chain. First, make a Chain for your entries to live in.
% echo "This is the payload of the first Entry in my chain" | factom-cli addchain -n thisIsAChainName -n moreChainNameHere $ec1

It makes the chain with ChainID: 23985c922e9cdd5ec09c7f52a7c715bc9e26295778ead5d54e30a0a6215783c8
Check the status of the Chain.

Evaluating Success
You can get some diagnostic info from the control panel (which incidentally doesn't control anything). Browse to http://localhost:8090.
Your Factom sandbox container is now setup, you're now ready to interact with the Factom blockchain! Why not follow one of the hello-world examples for your favorite client? Head over to the Hello-world examples section for an overview.
Setup a Factom Remote Server
On a remote machine, setup a Factom server. Both the client and server must be run of different machines.

Use the same directions as Install Factom Binaries and Configure Factomd for Sandbox use. Run factomd. Make sure that port 8110 is open on the server. Only factomd needs to be running on the remote server.
Setup Client to use Sandbox Server
Create a folder in your user home folder. The folder should be called .factom/m2. If factomd has been run on your computer before this folder will already exist and may already contain part of the Factom blockchain.
In a terminal on Linux or  Mac, run: 
mkdir -p ~/.factom/m2
or Windows: 
mkdir %HOMEDRIVE%%HOMEPATH%\.factom\m2
Save the configuration file factomd.conf to your .factom/m2 directory. Open factomd.conf and edit the following:
Change the line ServerPubKey from "0426a802617848d4d16d87830fc521f4d136bb2d0c352850919c2679f189613a" to "8cee85c62a9e48039d4ac294da97943c2001be1539809ea5f54721f0c5477a0a"
This will make factomd recognize the sandbox public key instead of the official public key.
Make sure NodeMode is set to FULL for the client node. 
Connect Local Factomd to Sandbox Server
The local machine should be set as a client in the factomd.conf, which is default. Run factomd this way, but use the remote Factom server's IP address.
factomd -network=CUSTOM -customnet="mycustomnet" -exclusive=true -peers="SERVERIP:8110" -prefix="notaserver"
Your Factom sandbox container is now setup, you're now ready to interact with the Factom blockchain! Why not follow one of the hello-world examples for your favorite client? Head over to the Hello-world examples section for an overview.
Run a Dockerized Factom sandbox
Setting up the factom sandbox
A current ANO maintains a docker image for a Factom sandbox. This tutorial assumes you know how to use docker and that it's installed.  To run the Factom sandbox container without any modifications, simply run one of the two below depending on what you need:
Quick start
Quick start with ports exposed
docker run -d --name fct-sandbox laende/fct-sandbox
docker run -d --name fct-sandbox -p "8088:8088" -p "8089:8089" -p "8090:8090" laende/fct-sandbox
The commands above run a Factom node with the following configuration:
Network is set to LOCAL
This will cause factomd to run on its own local network rather than the Factom main network.
NodeMode is set to SERVER
This will make factomd create a blockchain.
DirectoryBlockInSeconds is set to 20
Mainnet runs with 10 minute blocks (600 seconds). Easier to develop with shorter block times, but may cause some strange behavior and errors. 
logLevel is set to debug
This exports pointers to data which is added into Factom to the ~/.factom/data/export/directory. Adding new entries will add new files to the directory with the specified ChainID.
To make Factom's data persist it is recommended to mount a data volume at /root/.factom:

docker run -d -v /root/.factom --name fct-sandbox-volume laende/fct-sandbox
Alternatively, if you wish to do modifications to the factomd.conf file before running you can clone the repository from github:
git clone https://github.com/Laende/fct-docker.git
 Navigate to the fct-docker directory, which contains five files. To configure your local installation of factomd and factomwalletd edit the factomd.conf file. Once you’re happy with the changes, run:
docker build --tag=fct-sandbox .
and:
docker run -d -p "8088:8088" -p "8089:8089" -p "8090:8090" fct-sandbox
Importing wallet with funds to the sandbox container
Now we need a Factom wallet with some funds to start recording entries. We use a Factoid address which has a balance of 20000 FCT in the genesis block. It has since been depleted on mainnet, but can be used on sandbox systems.
The private key is: Fs3E9gV6DXsYzf7Fqx1fVBQPQXV695eP3k5XbmHEZVRLkMdD9qCK 
The public key is: FA2jK2HcLnRdS94dEcU27rF3meoJfpUcZPSinpb7AwQvPRY6RL1Q
Let's import this address to our sandbox container:
docker exec -it fct-sandbox factom-cli importaddress Fs3E9gV6DXsYzf7Fqx1fVBQPQXV695eP3k5XbmHEZVRLkMdD9qCK
This command should return the public key mentioned above. Note it down somewhere as we will be using it later. We now need an Entry Credit address which we’ll generate:
docker exec -it fct-sandbox factom-cli newecaddress
You should see an EC address returned (it starts with EC). Write down this address as well, as we’ll be using it later.
Your Factom sandbox container is now setup, you're now ready to interact with the Factom blockchain! Why not follow one of the hello-world examples for your favorite client? Head over to the Hello-world examples section for an overview..
Resetting the Blockchain
By default, Factom holds all the blockchain, wallet, etc data in the user's home directory in a folder called .factom/m2/custom-database. This may be a hidden folder, so make sure to display hidden folders on your OS.
To reset the blockchain, first close factomd and factom-walletd. Delete all the folders and files in .factom/m2/custom-database except factomd.conf.
