What is Explorer?
Explorer is an GUI tool that provides a highly usable interface for 0Chain services. Explorer renders all 0Chain configurations relevant  in one place. That saves a lot of time from operations, eliminating the need for looking storage config, transaction, and wallet information. Explorer seamlessly works with any 0chain service. Check out a video on how to use the GUI to upload, download, update, delete, and share files and folders on the 0Chain dStorage platform.

​
Getting Started with Explorer
To try the explorer visit the one 0Chain network at: https://beta.0chain.net/
Creating Wallet and Allocation
 Accessing the Explorer for first time from the browser will prompt you to create a wallet and allocation or recover wallet.
A wallet contains your ZCN tokens to perform storage functionalities on 0Chain dStorage. To recover a wallet you should have a mnemonic phrase for your old 0chain wallet. For instructions on how to recover using mnemonic visit the recover wallet section.​
 To create a new wallet and save files on 0chain decentralized network, click on create wallet and allocation.
After clicking on create wallet and allocation, you will be redirected to files sections of the 0Stor which is the 0Chain's decentralized storage platform. (The Files section will be highlighted with the light blue color and shows the list of the files uploaded by the user on 0Chain dStorage).
Check Wallet Balance
You can check your current ZCN token Balance in the upper right corner (which is 0.00 in the below screenshot). By default, 0.5 tokens are locked in write and read pools when you create a wallet.

Get Test Tokens
Storing files on 0Chain dStorage, require ZCN tokens to get some test tokens lets use the send me test ZCN feature located in the 0wallet section.
1. Navigate to 0Wallet on the upper right.
2. Click on Send me Test ZCN Blue Button at the centre.
3. You will see our Balance increased by 1 ZCN token in the upper right corner.
Storing and Sharing Files with Explorer
Once you have some ZCN tokens in your wallet, you can use explorer to store files through 0Stor 0Chain decentralized storage platform. 
1. Navigate to 0Stor in the upper left corner of Explorer dashboard.
2. You will see various sections listed: Allocations, Files Transactions, and Shared.
Allocations
Allocations by default is selected and highlighted in blue. The Allocations section will have various subsections listed (List of Allocations, Create new Allocation, Update Allocation, Lock Read Tokens, Lock Write tokens, Read Pool Info, and Write Pool Info). By default the List of Allocations subsection is selected and highlighted in blue.
List of Allocations
In the List of Allocations section, an allocation (a storage space) by default is created for you on the 0Chain dStorage network.
The allocation was created when you clicked on create wallet and allocation during your initial access to explorer. Every allocation has an allocation id and has a size. The default size here for the storage space specified by the 0Chain is about 2147483648 (2GB). Data shards and parity shards are set to 4 and 2 by default which specify download/upload speeds and availability for the allocation.
Also, the Allocation is selected by default (highlighted in green) for storing files since there is no other allocation listed.
Types of Allocations
Using Explorer you can create multiple storage spaces (allocations) of different types to suit your storage needs. A default allocation created by 0Chain is of 2GB in size but if you want an allocation that is larger and has better availability. You can create that by clicking on the create new allocation (+) button under the Allocations section.
After Clicking on Create new Allocation button it will be highlighted in blue and prompts you to specify a simple or advance allocation.
Creating a Simple Allocation
A simple allocation only requires the size of the storage space that has to be allocated and automatically determines the number of tokens that has to be locked for creating that storage space. For example let's create an allocation of size 4GB.
The Total cost and tokens locked came out to be $ 0.002060 and $ 0.0028170933. By clicking on create new allocation button, the new allocation will be created and you will be redirected to transactions sections where you can see the amount of tokens locked for your customized allocation.
 As you can see in the above screenshot, a new allocation with an id is created 2 minutes ago with 0.1 locked tokens and 0.5 locked read tokens*. The tokens are deducted from the wallet and total balance has become 0.4 on the upper right.
* Locking of read tokens might not be required depending upon the explorer implementation.

Now the allocation can be used to store files and is set as a default allocation. To verify the size of the allocation, click on the allocations button on the right.
Here you can verify the specified size of the allocation and select the allocation to use for storage.
Creating an Advance Allocation
An advance allocation can be created by specifying various other parameters other than size.
Preferred Blobbers: These are used by users to store files on their own blobbers (storage providers).
Data Shards: Increased Data Sharders provides high download/upload speeds for files. (Default is 4).
Parity Shards: Increased parity sharders ensures high availability. (Default is 2).
Size: Size of the storage space (Default is 2GB).
Write Price: Cost of writing data onto the allocation. A range has to be specified depending upon the size of the allocation and other parameters. (Lower write price means less amount of write pools tokens required for locking).
Read Price: Cost of reading data stored on the allocation. A range is specified depending upon the size of the allocation and other parameters. (Lower write price means less amount of write pools tokens required for locking).
Challenge Completion Time: Lower challenge completion time results into better SLA. (Default is 3600 sec).
 For instance, let's create a 2GB Allocation which has 5 Data Shards for fast downloads and 2500 seconds completion time for better SLA. 
As you can see, it requires 0.0015 tokens for creating allocation. Click on create new allocation button to create an advance allocation To verify allocation check your allocation info by navigating to 0Stor in the upper left corner of Explorer dashboard.
Here you can see the specified allocation details during the creation of an advance allocation.
Updating an Allocation
To update the configuration of an allocation using Explorer,
1.Navigate to the 0Stor
2.Click on update allocation.
Here Allocation ID for the allocation whose configuration has to be updated is required. Allocation Variables that can be changed for a particular allocation are:
Expiry: Allocation Expiry Time
Size: Size of the Allocation.
An allocation id can be fetched by clicking on list of allocations on the left .Here is a sample screenshot:
3.For example lets update the allocation which has 4294967296(4 GB) of size for smaller size (1GB) and decrease its expiry time to a day. Click on the allocation id which has a size of 4GB that is: 
4.You will see the following output .Copy the allocation id specified to the Hash variable.
 5. Navigate back to Update Allocation by clicking on 0Stor on the upper left area and paste the allocation id to change expiry date and size for a particular allocation.
