Validator / Lightning Node Setup

Hardware/OS requirements

  • 16 Gb HD, 2 cores, 8 GB Ram

  • Debian 12 GNU/Linux Operating System.

How to set up your Lightning node

The Easiest way: NaaS

Using a Node-as-a-Service (NaaS) service provider consists in delegating all technical aspects to a service provider.

Nodeops providers who support Script Network nodes:

    * [https://nodeops.xyz](https://nodeops.xyz)

The 1liner Installer

You would allocate a debian Operating system and run the 1-liner installer, converting it into a node in minutes.

The downloads screen provides access to different method for running a node.

Support for node installations has been discontinued for platforms Windows and Mac.

Here are the steps: https://download.script.tv

screenshot__downloads_1liner

This is the sequence of steps for a manual installation:

  • 1.- get a debian-12 VM in a datacentre or as a raspberry pi or headless computer. (e.g linode.com, digitalocean.com)

  • 2.- ssh as root. (Priviledged access to the VM command shell).

  • 3.- paste the 1-liner installer you copied from downloads page. Press Enter.

  • 5.- wait for a few minutes… Voila! your node is up and running!.

  • 6.- Follow on-screen instructions on further step like licensing and staking your node.

stv - The CLI interface

stv is the command you’d use to operate the node.

Have a detailed explanation of its functions in the sysop manual, available at

sysop_manual

script_tv__stvtool_manual.pdf

A walkthrough video is also available at

https://x.com/manic_beret/status/1865704546011377953

More on stv below.

Developer node

  • Build it all from sources. for devs and devops.

Follow instructions at our github page: https://github.com/scriptnetwork/script-4

You have successfully completed your node setup.

All following items check out:

  • ssh as root to your node. This action is perfomed ideally by muscle memory, but much better providing seamless experience is to set up passwordless authentication

      linux/Mac: `ssh root@<your node>`
          Windows: `putty` [download](https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html)
screenshot__user_node_root_login

  • switch to user ‘stv’ and go to home directory /home/stv (stv)

  • run the program stv

screenshot__user_node_stv_scriptcli

Automatic software updates

Automatic software updates feature is enabled by default. It can be disabled deleting the file /etc/cron.d/script_tv_updates and restating cron: systemctl restart cron

Check the Release Notes.

The document can also be found in the node at /var/script_tv/release_notes.md

Node bash shell

About GNU/Linux

Main SYSOP interface: Text Command-line console, also known as shell.

Linux prompts. Line Prefixes is given by the computer to indicate us context: user and path

        root:~$

SYSOP role operates under user root, and can control all aspects of the operating system. This prompt indicates that our path in the filesystem is /root (root home directory)

        root:/home/stv

This prompt indicate we are SYSOP, although our current path in the filesystem is /home/stv (stv user’s home directory again)

        stv:~$

Finally, this prompt indicates our hat is Script-Network user and that our current directory is home (/home/stv)

SYSOP/nodeop Role/hat: user root

Available commands for SYSOPs:

        * script_tv__uninstall.sh           # uninstalls the node software.
                * script_tv__test.sh                # subsystem health checks 
                * script_tv__ctl stop               # stops all services for node maintenance
                * script_tv__ctl start              # resume all services after node maintenance
                * cat /var/script_tv/data_sheet     # Prints Operational Data sheet detailing daemons, URLs and ports used among other technical data.

SCRIPT P2P Network. Nodeops the linux user stv

Changing to user stv from root

        root$ stv                # change to user stv

Returning back to root user (SYSOP mode)

        stv:~$ exit
                root$

stv - the CLI Command-Line-Interface to the script network

the stv command is an alias to the program bin/stvtool. It must always been executed as user stv.

Some of the commands are mentioned here below, but the full documentation for stv with all its functions can be found at

[script_tv__stvtool_manual.pdf](https://download.script.tv](https://download.script.tv/files/script_tv__stvtool_manual.pdf)

From the returned information we learn:

  • Our node address is 0x8d1F3236d790415d631d554091dE7A25913FB561

  • we are on testnet network

  • our peer_id is our node address, for node-node communications.

  • The genesis block hash 0x42a81f3f7ef0a5297997c8428ae945d5176f07082224b006f1979a5ebbe2744c must match on all nodes of this network.

  • Other information about the chain: block height, last block (current_hash).

  • Syncing indicates the type of activity that is going on. true/false indicates whether an sync activity is ongoing or not.

Your keys are stored in directory /home/stv/script4/wallet/keys/plain

        stv:~$ find script4/wallet/keys/plain -exec cat {} \;

As protection against loss, we encourage you to backup the keys directory.

Backup

Use stv backup to produce a downloadable file with your keys: It provides with scp commands ready to be executed in remote computers to fetch the backup, either from inside the LAN or from internet (WAN).

stv:~$ stv backup
        Deleting previous backup files
        find: unknown predicate `-maxdepth=1'
        Copying gov key from /home/stv/script4/gov/key/

testnet Faucet:

Obtain testnet tokens from our faucet at script.tv

Every script node has a faucet service that would -kindly- transfer you funds on request. The objective of testnet is to give users the opportunity to test the system using ‘play money’.

However if we run a mainnet node we would use an exchange and buy tokens instead.

Using stv CLI tool you would invoke faucet this way:

stv:~$ stv faucet
        Tx 0x0c91f018443240fc69cc438e793045966ef350da22bf19eca9ba6a1746e3b68c
        Explorer link: https://explorer-user-testnet.mm.cto.script.tv/txs/0x0c91f018443240fc69cc438e793045966ef350da22bf19eca9ba6a1746e3b68c
        Funds will arrive in seconds, check balance.

And seconds after verify balance:

stv:~$ stv balance
        Address 0x8a95c6C85A4eB294c4dCB764867717C7CDf1f072
            SCPT: 1000.000000000000000000
            SPAY: 100.000000000000000000

The command can be repeated as many times as wished up to a balance limit of 1M. We can easy earn tokens this way.

By feeding with tokens your node address your faucet is automatically enabled using it as source of funds and making the faucet service available to other participants in the script network.

Lightning node. Main setup workflow.

Lightning nodes are nodes that cooperate securing and guaranteeing its resilience and reliability, forming a trustable network of untrusted nodes, following the breakthrough by Satoshi Nakamoto.

In order to become one your just installed node must be upgraded.

The steps for upgrading the software are:

  • acquire 20.000 SCPT (or tSCPT for testnet)

  • purchase a Lightning license.

  • stake the node.

With the stv interface:

stv:~$ stv --lightning faucet      #only on testnet
        stv:~$ stv --lightning buy_license
        stv:~$ stv --lightning stake

An example of such run is:

stv@:~$ stv --lightning faucet
        Faucet for lightning.
        Tx 0x14f85252c2175e1290c1924b0d4630df6333fa45d22ea5d505128b34a318cb93

For those who have purchased a license via https://nodesale.script.tv

the steps for upgrading the node to lighning are:

stv:~$ stv redeem
        stv:~$ stv --lightning stake

The redeem function will give you a personalized URL you would use to prove the ownership of the wallet with which you did the purchase. Once verified you would obtain a lighniung license for the node.
