SDS

The Stratos Decentralized Storage (SDS) network is a scalable, reliable, self-balancing elastic acceleration network driven by data traffic. It accesses data efficiently and safely. The user has the full flexibility to store any data regardless of the size and type.

SDS is composed of many resource nodes (also called PP nodes) that store data, and a few meta nodes (also called indexing or SP nodes) that coordinate everything. The current repository contains the code for resource nodes only. For more information about meta nodes, we will open source it once it's ready.

Here, we provide a concise quickstart guide to help set up and run a SDS resource node. For more details of SDS as well as the Tropos-Incentive-Testnet rewards distribution, please refer to Tropos Incentive Testnet.

Building a Resource Node From Source

git clone https://github.com/stratosnet/sds.git
cd sds
git checkout v0.8.1
make build

Then you will find the executable binary ppd under ./target

Installing the Binary

The binary can be installed to the default $GOPATH/bin folder by running:

make install

The binary should then be runnable from any folder if you have set up go env properly

Creating a SDS Resource Node

Creating a Root Directory for Your Resource Node

To start a resource node, you need to be in a directory dedicated to your resource node. Create a new directory, or go to the root directory of your existing node.

# create a new folder 
mkdir rsnode
cd rsnode

Configuring Your Resource Node

Next, you need to configure your resource node. The binary will help you create a configuration file at configs/config.toml.

ppd config -w -p
# following the instructions to generate a new wallet account or recovery an existing wallet account

You will need to edit a few lines in the configs/config.toml file to configure your resource node.

First, make sure or change the SDS version section in the configs/config.toml file as the following.

[version]
app_ver = 8
min_app_ver = 8
show = 'v0.8.1'

To connect to the Stratos-chain Tropos testnet, make the following changes:

stratos_chain_url = 'https://rest-tropos.thestratos.org:443' 

and then the indexing node list:

[[sp_list]]
p2p_address = ''
p2p_public_key = ''
network_address = '18.223.175.117:8888'
[[sp_list]]
p2p_address = ''
p2p_public_key = ''
network_address = '52.13.28.64:8888'
[[sp_list]]
p2p_address = ''
p2p_public_key = ''
network_address = '46.51.251.196:8888'
[[sp_list]]
p2p_address = ''
p2p_public_key = ''
network_address = '35.73.160.68:8888'
[[sp_list]]
p2p_address = ''
p2p_public_key = ''
network_address = '35.74.33.155:8888'
[[sp_list]]
p2p_address = ''
p2p_public_key = ''
network_address = '18.130.202.53:8888'
[[sp_list]]
p2p_address = ''
p2p_public_key = ''
network_address = '3.9.152.251:8888'

You also need to change the chain_id to the value visible Stratos Explorer right next to the search bar at the top of the page. Currently, it is tropos-4.

chain_id = 'tropos-4'

Finally, make sure to set the network_address to your public IP address and port.

Please note, it is not the meta node network_address in [[sp_list]] section

# if your node is behind a router, you probably need to configure port forwarding on the router
port = '18081'
network_address = 'your node external ip' 

Acquiring STOS Tokens

Before you can do anything with your resource node, you will need to acquire some STOS tokens.
You can get some by using the faucet API:

  curl --header "Content-Type: application/json" --request POST --data '{"denom":"ustos","address":"put_your_wallet_address_here"} ' https://faucet-tropos.thestratos.org/credit

Just put your wallet address in the command above, and you should be good to go.

Starting Your Resource Node

Once your configuration file is set up properly, and you own tokens in your wallet account, you can start your resource node.

to start the node as a daemon in background without interactivity:

# Make sure we are inside the root directory of the resource node
cd rsnode
# start the resource node
ppd start

Starting Mining

In order to interact with the resource node, you need to open a new COMMAND-LINE TERMINAL, and enter the root directory of the same resource node. Then, use ppd terminal command to start the interaction.

# Open a new command-line terminal
# Make sure we are inside the root directory of the resource node
cd rsnode
# Interact with resource node through a set of "ppd terminal" subcommands
ppd terminal

Registering to a Meta Node

Your resource node needs to register to a meta node before doing anything else.
In the ppd terminal command-line terminal, input one of the two following identical commands:

rp
# or
registerpeer

Activating the Resource Node by Staking

Now you need to activate your node within the blockchain.
Use this command in the ppd terminal command-line terminal:

activate stakingAmount feeAmount gasAmount

stakingAmount is the amount of uSTOS you want to stake. A basic amount would be 1000000000.

feeAmount is the amount of uSTOS to pay as a fee for the activation transaction. 10000 would work. it will use default number if not provide

gasAmount is the amount of gas to use for the transaction. 1000000 would be a safe number. it will use default number if not provide

Resource node will start to receive tasks from meta nodes and thus gain mining rewards automatically after it has been activated successfully.

What to Do With a Running Resource Node?

Here are a set of ppd terminal subcommands you can try in the ppd terminal command-line terminal.

You can find more details about these subcommands at ppd terminal subcommands

Check the current status of a resource node

status

Update stake of an active resource node

updateStake stakeDelta fee gas isIncrStake 

stakeDelta is the absolute amount of difference between the original and the updated stake. It should be a positive integer, in the unit of ustos.

isIncrStake is a flag with 0 for decreasing the original stake and 1 for increasing the original stake.

When a resource node is suspended, use this command to update its state and re-start mining by increasing its stake.

Purchase Ozone

Ozone is the unit of traffic used by SDS. Operations involving network traffic require ozone to be executed.
You can purchase ozone with the following command:

prepay purchaseAmount feeAmount gasAmount

purchaseAmount is the amount of uSTOS you want to spend to purchase ozone.

The other two parameters are the same as above.

Query Ozone Balance of Resource Node's Wallet

getoz WALLET_ADDRESS

Upload a File

put FILE_PATH

FILE_PATH is the location of the file to upload, starting from your resource node folder. It is better to be an absolute path.

Upload a media file for streaming

Streaming is the continuous transmission of audio or video files(media files) from a server to a client. In order to upload a streaming file, first you need to install a tool ffmpeg for transcoding multimedia files.

putstream FILE_PATH

List Your Uploaded Files

list
# or
ls

Download a File

get sdm://WALLET_ADDRESS/FILE_HASH SAVE_AS

Every file uploaded to SDS is attributed a unique file hash. You can view the file hash for each of your files when your list your uploaded files.
You can use an optional parameter SAVE_AS to rename the file after downloading

Delete a File

delete FILE_HASH

Share a File

sharefile FILE_HASH DURATION IS_PRIVATE

DURATION is the time period(in seconds) when the file share expires. Put 0 for unlimited time.

IS_PRIVATE is whether the file shared should be protected by a password. Put 0 for no password, and 1 for a password.

After this command has been executed successfully, SDS will provide a password to this shared file, like SharePassword 3gxw. Please keep this password for future use.

List All Shared Files

allshare

Download a Shared File

getsharefile SHARE_LINK PASSWORD

Leave the PASSWORD blank if it's a public shared file.

Cancel File Share

cancelshare SHARE_ID

View Resource Utilization

Type monitor to show the resource utilization monitor, and stopmonitorto hide it.

# show the resource utilization monitor
monitor

# hide the resource utilization monitor
stopmonitor

You can exit the ppd terminal command-line terminal by typing exit and leave the ppd start terminal to run the resource node in background.
