Command Line Interface

Getting Started

Once SASEUL is installed on your node machine, the node is now ready to run. You can execute various predefined SASEUL commands on cli to directly operate your SASEUL node.

You can execute SASEUL commands like below.

1. For docker installed nodes,

   docker exec -i saseul-node saseul-script {commandName}

2. For source code installed nodes, move to the path below.

   cd <Path to source code>
   ./src/saseul-script

Stop

• Stop the node.
• If the stop command fails, the process will be killed.

Usage: : $ saseul-script Stop

Restart

• Restart the node.
• Execute the Start command followed by the Stop command in sequence.

Usage: : $ saseul-script Restart

Kill

• Kill all running processes.

Usage: : $ saseul-script Kill

StartMining

• Starts the mining process.
• It only works when the saseul process is running.

Usage: : $ saseul-script StartMining

StopMining

• Stops the mining process.
• It only works when the saseul process is running.

Usage: : $ saseul-script StopMining

Info

• Display current status information of the node.

Usage: : $ saseul-script Info

Setup Operation

SetEnv

• Set the env information of the node.
• You can configure node information, peer information, miner address, and node endpoint.

Usage: : $ saseul-script SetEnv : $ saseul-script SetEnv —miner

Option	Type	Description
-a —all		Set all env information.
-n —node	string	Set node key
-p —peer	string	Set peer key
-m —miner	string	Set miner address
-e —endpoint	string host:port	Set endpoint ("": reset)
-h —help		help

GetEnv

• Display all env information of the node.
• You can check the node information, peer information, miner address, and node endpoint.

Usage: : $ saseul-script SetEnv : $ saseul-script SetEnv —miner

Option	Type	Description
-a —all		Display all information
-n —node	(null, private_key, public_key, address)	Display node information
-p —peer	(null, private_key, public_key, address)	Display peer information
-m —miner		Display miner address
-e —endpoint		Display endpoint
-h —help		help

Tracker Operation

AddTracker

• Adding a tracker to the peer-to-peer search algorithm.
• If the node is running, peers will typically connect within about 2-3 minutes on average.

Usage: : $ saseul-script AddTracker —peer

ResetTracker

• Deletes all tracker information.
• The peer information is reset to main.saseul.net, aroma.saseul.net, and blanc.saseul.net.

Usage: : $ saseul-script ResetTracker

Peer

• Display peer information.
• Peers containing the node’s data are connected as “Peer”
• Peers not containing the node’s data are connected as “Known Hosts”
• Unreachable peers are not displayed.

Usage: : $ saseul-script Peer

Data Operation

Reset

• Delete all data.
• Tracker data and environment information data will not be deleted.

Usage: : $ saseul-script Reset

ForceSync

• Synchronize blocks quickly from a specific peer.
• The data consistency check is performed after synchronization, so if a malicious node synchronizes, the node can be forked from the network.

Usage: : $ saseul-script ForceSync —peer

RestoreBlock

• Delete some of the latest blocks and resynchronize.
• Deletes the specified number of Resource Blocks and also the Main Blocks recorded in the Resource Blocks.
• This is a feature used to recover block data in case the network is forked.

Usage: : $ saseul-script RestoreBlock —count

RewindBlock

• Delete unfinalized resource blocks and resynchronize.
• This is a function used when there is an error in the consistency of the latest block data.

Usage: : $ saseul-script RewindBlock —count

Rebundling

• Recomputes the status data based on block information.
• This is a function used when there is an error in the consistency of the latest block data.

Usage: : $ saseul-script Rebundling

Smart Contracts and Requests

SendTransaction

• Execute the method of the smart contract to create a transaction and broadcast it.

Usage: : $ saseul-script SendTransaction : $ saseul-script SendTransaction —method Send —data ’{“to”:"

",“amount”:“1000000”}‘

Option	Type	Description
-c —cid	string	Enter the contract ID to call.
-m —method	string	Enter the name of the method to be called.
-k —key	string	Enter the private key to sign the transaction (Optional)
-d —data	string	Enter transaction data (JSON Format)
-h —help		help

LocalRequest

• Execute the method of a smart contract based on data stored in the current node, and display the information

Usage: : $ saseul-script LocalRequest : $ saseul-script LocalRequest —method GetBalance —data ’{“address”:"
