Understanding the XRP Ledger and Its Validators

Before we get into the nitty-gritty of setting up your own validator, let’s quickly unpack what the XRP Ledger XRPL is and why validators are so important to it.

The XRP Ledger is a public, decentralized blockchain that was created for fast, low-cost global payments. It’s distinct from many other cryptocurrencies because it wasn’t designed for mining or staking in the traditional sense. Instead, it uses a unique process called the Ripple Protocol Consensus Algorithm RPCA. Think of it like a group of trusted friends all agreeing on the same version of events in real-time, rather than waiting for one person to solve a complex puzzle like Bitcoin’s Proof-of-Work or for people to put up large sums of money as collateral like Ethereum’s Proof-of-Stake.

So, what exactly does an XRP validator do? Essentially, these are independent servers, run by individuals, universities, companies, or exchanges, that work together to maintain the integrity of the XRPL. Their main job is to verify and approve transactions by constantly checking for authenticity and proper formatting. Every three to five seconds, these validators reach a supermajority consensus, meaning at least 80% of trusted validators agree on the next set of transactions to be added to the ledger. This incredibly fast consensus process is what allows the XRPL to handle up to 1,500 transactions per second and potentially more with payment channels, with transactions achieving finality in just 3-5 seconds.

Beyond just verifying transactions, validators also play a crucial role in the XRPL’s governance. They have the opportunity to vote on amendments and fees, which are proposed changes to the protocol. This gives them a real voice in shaping the network’s evolution, ensuring it remains robust and adapts to new needs. Without these validators, the XRP Ledger wouldn’t be able to achieve its speed, efficiency, and security, making them the true backbone of the network.

Is Becoming an XRP Validator Right for You?

Running an XRP validator isn’t for everyone, and it’s important to understand the realities before you commit. It’s a role that demands technical proficiency, dedication, and a commitment to the network’s health.

The “No Direct Rewards” Reality for Mainnet Validators

One of the biggest distinctions for XRPL mainnet validators, compared to many other blockchain validators, is the absence of direct economic incentives in the form of XRP rewards. This is a deliberate design choice. The XRP Ledger’s consensus mechanism doesn’t rely on “mining” or “staking” to issue new tokens or distribute fees to validators. Instead, transaction fees on the XRPL are small amounts of XRP that are burned, reducing the total supply over time and acting as a deterrent against spam. This means that if you’re looking to run a mainnet validator purely for a passive income stream through direct XRP payouts, you might be in for a surprise.

So, why do people run them then? The motivation for mainnet validators is typically rooted in a demonstrated interest in the long-term health and decentralization of the XRP Ledger. Validators gain the ability to influence the network’s direction by voting on amendments and proposed changes, and they contribute to its overall security and stability. For businesses, exchanges, or institutions that heavily rely on the XRPL, running a validator is a way to ensure the network remains reliable and aligned with their interests. For individuals, it’s often a passion project, a way to contribute to a technology they believe in, and to ensure they have their own independent, trusted view of the ledger.

XRPL EVM Sidechain Validators: An Alternative for Rewards

Now, here’s a crucial point: while the mainnet XRPL doesn’t directly reward validators, an exciting development is the XRPL EVM Sidechain. This is a separate network designed to bring Ethereum’s smart contract capabilities to the XRP Ledger, and it will reward its chain validators with XRP tokens. If earning direct XRP rewards for validation is a key driver for you, becoming a validator on the XRPL EVM Sidechain could be the path. This sidechain operates with its own set of validator requirements and mechanisms, and it collects gas fees in XRP to reward its validators. It’s a growing area, and being an early participant could offer different opportunities.

Commitment & Responsibilities

Regardless of whether you choose the mainnet or the EVM sidechain, being a validator is a serious commitment. You’ll need to: Buying a 1 kg Gold Bar: Your Ultimate Guide to Smart Investment

• Maintain High Availability: Strive for 100% uptime. A good validator is always running and submitting votes for every proposed ledger. Downtime can impact your influence and reliability.
• Agree with the Network: Your validator’s votes should consistently match the consensus outcome. Disagreement might signal outdated software or configuration issues.
• Be Timely: Quick processing and agreement are key to the XRPL’s efficiency.
• Be Involved: Staying updated with XRPL developments and participating in community discussions e.g., XRPChat, Discord is crucial. Announcing maintenance ahead of time is a good practice.

Technical Savvy Required

This isn’t a “set it and forget it” kind of task. You’ll need:

• Linux Command Line Skills: Most rippled installations and configurations happen via command line on a Linux operating system.
• Basic Networking Knowledge: Understanding ports, firewalls, and network connectivity is essential.
• Familiarity with Blockchain Concepts: A solid grasp of how decentralized networks and consensus mechanisms work will help you troubleshoot and contribute effectively.

If you’re ready for the challenge and motivated by contributing to a fast, efficient, and decentralized financial future, then let’s get into the specifics.

Essential Gear: Hardware and Software Requirements

Alright, let’s talk about the hardware and software you’ll need to get your XRP validator up and running. Remember, consistent performance is key for a good validator, so aiming for the recommended specifications rather than just the minimum is always a smart move.

Operating System

For stability, security, and compatibility, Linux is the go-to operating system for running rippled servers. SE Ranking vs Semrush vs Ahrefs: Which SEO Tool Should You Pick in 2025?

• Recommended: Ubuntu LTS, latest release, Red Hat Enterprise Linux latest release, or a compatible Debian-based Linux distribution. Ubuntu 20.04 or later is often recommended for simplicity.

CPU Processor

Your CPU needs to handle the parallel processing involved in validation and network synchronization.

• Minimum: 64-bit x86_64, 4+ cores.
• Recommended for Production: 3+ GHz 64-bit x86_64 processor with 8+ cores e.g., Intel Xeon. Higher core counts help under heavy load.

RAM Memory

Sufficient memory is vital for smooth operation, especially during peak network load and for handling large database operations.

• Minimum: 16 GB+.
• Recommended for Production: 64 GB.

Disk Storage

Fast storage is critical for maintaining a responsive node database and quickly processing state updates. Sustained IOPS Input/Output Operations Per Second are more important than burst speeds.

• Type: SSD / NVMe NVMe is generally faster.
• Performance: 10,000 IOPS sustained not burst or peak or better.
• Capacity: Minimum 50 GB for the database partition. For an XRPL EVM Sidechain node, 250 GB SSD minimum is suggested, with 1TB cloud storage for recommended setups.
• Important Note: Avoid using Amazon Elastic Block Store AWS EBS as its latency can be too high to reliably sync.

Network

A stable and fast internet connection is non-negotiable for timely propagation of blocks and efficient peer discovery.

• Speed: A stable 100 Mbps connection or faster is recommended. Some suggest speeds above 200 Mbps for optimal performance, though lower speeds might work for non-intensive use.
• Interface: Enterprise data center network with a gigabit network interface on the host is recommended for production environments.
• Location: Choose a server location with low latency to the XRPL network, often near major data centers in the U.S. or Europe.

Software

• rippled server: This is the core software that runs the XRP Ledger node and enables validation.
• validator-keys tool: Included with the rippled package, used to generate your validator keys.
• SSH Client: For securely accessing your server remotely e.g., Termius, PuTTY.

Choosing Your Server Environment

You essentially have two main options for hosting your validator:

1. Cloud Virtual Private Server VPS: This is often the easiest and most flexible option, especially for beginners. Providers like Amazon Web Services AWS, Google Cloud, or Hetzner offer virtual machines that meet these specifications. This typically costs anywhere from $20-$50 per month, depending on the specs you choose.
2. Dedicated Physical Server: If you have the expertise and want full control, you can build or purchase a physical server. This gives you direct control over hardware, but also means you’re responsible for all maintenance, power, cooling, and physical security.

For reliable performance in production environments, running on bare metal with the recommended specs is often suggested. However, a well-configured cloud VPS can also be highly effective.

Your Step-by-Step Roadmap to Becoming an XRP Validator

let’s get into the practical steps of setting up your very own XRP Ledger validator. This might look like a lot, but we’ll break it down into manageable parts. I’ll assume you’re using a fresh Ubuntu Linux server, which is a popular and well-documented choice.

Step 1: Choose Your Server Environment

First things first, decide where your validator will live. As we discussed, a Cloud VPS is usually the simplest route. Pick a reputable cloud provider Hetzner, AWS, Google Cloud are common choices and spin up a new virtual machine that meets or exceeds the recommended hardware specifications we just covered. Make sure you select a Linux distribution like Ubuntu LTS. Once your server is provisioned, you’ll get an IP address, a username often root or ubuntu, and a password or an SSH key. Keep these safe! What is a Commercial Blender? The Ultimate Guide for Your Business

Step 2: Install rippled The Core Software

This is where you’ll start getting your hands dirty with the command line. You’ll use an SSH client like Termius, which is pretty user-friendly for beginners to connect to your server.

1. Connect to Your Server: Open your SSH client and connect using the IP address, username, and password/SSH key provided by your cloud provider.
2. Update Your System: It’s always a good idea to start with an up-to-date system.

   sudo apt update && sudo apt upgrade -y
   

3. Install Essential Dependencies:
   sudo apt install -y apt-transport-https ca-certificates software-properties-common
4. Add Ripple’s Package Signing GPG Key: This verifies the authenticity of the rippled software.
   wget -q -O – https://repos.ripple.com/repos/api/gpg/key | sudo apt-key add –
5. Add the Ripple Repository to Your System:
   echo “deb https://repos.ripple.com/repos/rippled-deb $lsb_release -cs stable” | sudo tee /etc/apt/sources.list.d/ripple.list
6. Update Your Package List Again and Install rippled:
   sudo apt update
   sudo apt install -y rippled
   This command downloads and installs the rippled server software.

Step 3: Generate Validator Keys & Token

Now that rippled is installed, you need to generate specific keys that identify your server as a validator on the network.

1. Navigate to the rippled Bin Directory:
   cd /opt/ripple/bin/

    ./validator-keys create_keys
   This command will output two important pieces of information: a `validation_secret` and a `validation_public_key`. Crucially, it will also tell you where it stored the `validator-keys.json` file usually in `/home/your-user/.ripple/`. Seriously, store this `validator-keys.json` file securely and offline, like on an encrypted USB drive! If you lose it, you lose control of your validator.
   

2. Generate a Validator Token: This token will be placed in your rippled configuration file.
   ./validator-keys create_token –keyfile /home/your-user/.ripple/validator-keys.json
   Replace /home/your-user/.ripple/validator-keys.json with the actual path if it’s different. This command will output your validator_token. Copy this entire token, including the quotes, as you’ll need it in the next step.

Step 4: Configure rippled for Validation

You need to tell your rippled server to actually act as a validator. This involves editing its main configuration file.

1. Open the rippled.cfg File:
   sudo nano /etc/opt/ripple/rippled.cfg
   You can use vim if you prefer.
2. Add Your Validator Token: Scroll to the very bottom of the file. You’ll want to add a stanza and paste the token you generated in the previous step. It should look something like this:

   eyJ…your_long_validator_token_here…xyz
   Make sure there are no extra spaces or line breaks.

3. Optional: Configure Voting for Fees and Reserves: As a validator, you can also vote on proposed changes to transaction costs and account reserves. If you want to express your preferences, you can add a stanza. For instance, to vote for common values:

   reference_fee = 10
   account_reserve = 10000000 . 10 XRP
   owner_reserve = 2000000 . 2 XRP The Ultimate Guide to Manitowoc Commercial Ice Makers: Chilling Your Business Needs

4. Save and Exit: If using nano, press Ctrl+X, then Y to confirm saving, and Enter.

Step 5: Connect to the Network & Start Service

With the configuration done, it’s time to bring your validator online!

1. Restart the rippled Service:
   sudo systemctl restart rippled.service
2. Verify Your Validator is Running: Give it a minute or two to start and sync. Then, you can check its status and connection.
   sudo systemctl status rippled.service
   You should see “active running”.
   To get more detailed information and confirm it’s acting as a validator, use the server_info command:
   /opt/ripple/bin/rippled server_info
   Look for a pubkey_validator field in the output. this confirms it’s validating. You can also check the peers command to see if your server is connecting to other nodes. If the peers array is null, something’s wrong.

Step 6: Domain Verification & Community Engagement Crucial for Trust

Your validator is technically running, but to gain trust and influence, you need to make yourself known to the community and other validators.

1. Domain Verification: This is a critical step to prove your validator is legitimate and controlled by a known entity. You’ll need to:
   • Acquire a Domain: Purchase a domain name e.g., myxrplvalidator.com.
   • Host an xrp-ledger.toml File: On this domain, create and host a file named xrp-ledger.toml at the root e.g., https://myxrplvalidator.com/.well-known/xrp-ledger.toml. This file will contain details about your validator, including its public key, to establish a two-way link between your domain and your validator.
   • Configure DNS: Point your domain’s A record to a web server which can be separate from your validator server that hosts this TOML file.
2. Share Your Public Key: Share your validator’s public key the validation_public_key from Step 3 with the public, especially with other rippled operators. You can do this on your website, social media, or in community forums like XRPChat.
3. Engage with the XRPL Community: Participation in the community is vital. This helps you stay informed about network changes, best practices, and allows others to recognize your commitment. Join official XRPL Discord channels or forums. For the XRPL EVM Sidechain, joining their Discord channel and introducing your validator is a specific step to be proposed for their official validator set.

Congratulations! You’ve successfully set up your XRP Ledger validator. Your server is now contributing to the security and decentralization of the network.

The Unique Node List UNL: Your Path to Influence

You’ve got your validator up and running, which is a huge step! But just running a validator doesn’t automatically give you influence on the XRP Ledger. This is where the Unique Node List UNL comes into play, and it’s super important to understand. Is vpn safe for meetings

Think of a UNL as a personalized “trusted circle” for each rippled server. Every server operator on the XRPL configures their own UNL, which is essentially a list of other validators they trust not to collude or act maliciously. When your validator proposes a new ledger, other servers will only consider your vote if your validator is on their UNL. This trust-based system is a core part of the XRPL’s security model, making it resilient to Sybil attacks where a malicious actor tries to gain control by simply running many nodes because simply adding more validators doesn’t automatically grant influence.

How Your Validator Gets “Trusted”

So, how do you get your validator on other people’s UNLs? It boils down to reliability, transparency, and community trust.

• Default UNLs dUNLs: Most new rippled servers initially default to using curated lists of trusted validators published by entities like the XRP Ledger Foundation XRPLF and Ripple. These lists are seen as reliable sources of consensus.
• Demonstrate Reliability: To get on these published lists, or for individual operators to add you to their custom UNLs, your validator needs to consistently show:
  • High Uptime: As close to 100% as possible. A validator that’s frequently offline won’t be trusted.
  • Agreement: Your validator’s votes should consistently align with the rest of the network’s consensus.
  • Timeliness: Quickly processing and agreeing on ledgers is essential.
• Domain Verification: This is a crucial step to build trust. By linking your validator’s public key to a public domain you own and hosting an xrp-ledger.toml file, you provide verifiable proof of your identity and commitment. This helps UNL publishers and other operators understand who runs your validator.
• Community Engagement: Actively participating in the XRPL community forums like XRPChat or Discord can help you connect with other operators, share your validator’s details, and build a reputation for being a responsible and engaged member. UNL publishers often have their own criteria for adding validators, and community standing can certainly play a role.

The more your validator is included in other UNLs, the more influence it will have in the consensus process and in voting on amendments. It’s a meritocracy based on consistent, honest participation.

Maintaining a Healthy Validator: Ongoing Tasks

Setting up your XRP validator is a fantastic accomplishment, but the work doesn’t stop there. Running a healthy, influential validator is an ongoing commitment. Think of it like taking care of a garden. it needs continuous attention to thrive. Starlink & VPNs: The Ultimate Guide to Staying Private and Unrestricted with Satellite Internet

Here are the key ongoing tasks you’ll need to perform:

1. Monitoring Performance: You need to keep a close eye on your server’s vital signs.

   • CPU, RAM, Disk Usage: Use tools like top or htop Linux command-line utilities to monitor your server’s resource consumption. Ensure these metrics stay well below 80% on average to prevent bottlenecks, especially during peak network activity.
   • Network Synchronization: Check that your rippled server is consistently synced with the network. If it falls behind, it can’t participate effectively in consensus. The server_info command can give you insights into its sync status.
   • Validator Status: Regularly verify that your validator is active and proposing ledgers using sudo systemctl status rippled.service and the rippled server_info command.

2. Regular Software Updates: The rippled software is constantly being improved and updated with new features, security patches, and protocol amendments.

   • Stay Informed: Keep an eye on official XRPL channels website, GitHub, social media for new releases.
   • Timely Updates: When new versions are released, you need to update your server promptly. Running outdated software can lead to your validator disagreeing with the network and losing influence. Manual updates are often recommended for validators so you can troubleshoot any issues immediately.

3. Backups: Your validator keys are incredibly important.

   • Key Files: Always have secure, offline backups of your validator-keys.json file. Losing these keys could mean losing control of your validator and the ability to operate it under your established identity.
   • Configuration Files: It’s also a good idea to back up your rippled.cfg file, especially after making changes.

4. Security Practices: Protecting your server from unauthorized access and attacks is paramount. How to Master Crypto Trading: Your Ultimate Guide

   • Firewall Rules: Configure your server’s firewall e.g., ufw on Ubuntu to only allow necessary inbound and outbound traffic. For example, only allow SSH access from specific IP addresses.
   • SSH Key-Based Authentication: Always use SSH keys instead of passwords for remote access to your server. This is much more secure.
   • Regular Security Audits: Periodically review your server’s security settings and logs.
   • No Public WebSocket Access: Your validator server should not be publicly accessible via WebSocket or any other public access method as a precaution against DDoS attempts.

5. Community Engagement: Staying connected with the XRPL community isn’t just for getting your validator noticed. it’s also crucial for ongoing maintenance.

   • Announce Downtime: If you need to perform scheduled maintenance that will take your validator offline, communicate this to the community beforehand.
   • Discuss Issues: If you encounter unexpected problems, the community can be a valuable resource for troubleshooting.

By diligently performing these ongoing tasks, you’ll ensure your XRP validator remains a reliable, trusted, and influential participant in the XRP Ledger network.

XRP Validator vs. Other Blockchain Validators

It’s helpful to put the XRP Ledger’s validation process into context by comparing it to other major blockchains. This really highlights why the XRPL approach is so unique.

Bitcoin Proof-of-Work – PoW

• Consensus: Bitcoin uses Proof-of-Work. Miners compete to solve complex cryptographic puzzles to add new blocks to the blockchain.
• Incentive: Miners are rewarded with newly minted Bitcoin block rewards and transaction fees for successfully adding a block. This incentivizes significant computational power.
• Energy Consumption: PoW is notoriously energy-intensive due to the competitive mining process.
• Finality: Transactions take longer to achieve finality, typically around 10 minutes per block, with further confirmations adding security.

Ethereum Proof-of-Stake – PoS

• Consensus: Since “The Merge,” Ethereum uses Proof-of-Stake. Validators “stake” lock up a significant amount of ETH currently 32 ETH as collateral.
• Incentive: Validators are randomly chosen to propose and attest to new blocks and, in return, earn staking rewards new ETH and a portion of transaction fees. Malicious or unreliable behavior can lead to “slashing” losing some of their staked ETH.
• Energy Consumption: PoS is far more energy-efficient than PoW.
• Finality: Transactions on Ethereum achieve finality much faster than Bitcoin, typically in a few minutes, though it’s still generally slower than XRP Ledger.

XRP Ledger Ripple Protocol Consensus Algorithm – RPCA

• Consensus: The XRPL uses a unique Federated Byzantine Agreement FBA model, specifically the RPCA. Validators agree on the order and validity of transactions every 3-5 seconds by reaching an 80% supermajority consensus on their Unique Node Lists UNLs. There is no “mining” or “staking” of XRP to secure the mainnet.
• Incentive: As discussed, mainnet XRPL validators do not receive direct economic incentives like XRP rewards or a share of transaction fees. Transaction fees are burned. Motivations typically include contributing to decentralization, network security, and having a voice in governance voting on amendments and fees. However, the newer XRPL EVM Sidechain does plan to reward its validators with XRP for securing that specific chain.
• Energy Consumption: RPCA is a lightweight and highly energy-efficient process, significantly more so than PoW, and even generally more efficient than PoS due to its differing trust model.
• Finality: The XRPL boasts extremely fast transaction finality, typically within 3-5 seconds. This speed is crucial for its adoption in cross-border payments.

Key Takeaway: The XRPL stands out because it achieves high speed and low cost without the traditional “rewards” model for its mainnet validators. Instead, it relies on a web of trust and the shared interest of its participants in a healthy, efficient network. While this means no direct XRP earnings for mainnet validation, it also means a highly energy-efficient and rapid settlement system, different from both Bitcoin’s competitive mining and Ethereum’s staked collateral approach. If direct rewards are your focus, exploring the XRPL EVM Sidechain validation would be more aligned. How and Where to Invest in Crypto: Your Friendly Guide for Beginners

Frequently Asked Questions

Do XRP validators earn money?

For validators on the main XRP Ledger XRPL, the answer is generally no, not in the form of direct XRP rewards or transaction fees. Unlike Proof-of-Work like Bitcoin or Proof-of-Stake like Ethereum, the XRPL’s consensus mechanism doesn’t allocate rewards or transaction fees to validators. Transaction fees on the XRPL are small amounts of XRP that are permanently destroyed, reducing the total supply. The primary incentives for running a mainnet XRPL validator are contributing to the network’s decentralization and security, having a voice in its governance e.g., voting on amendments and fees, and promoting a healthy ecosystem that benefits all XRP users. However, it’s important to note that the newer XRPL EVM Sidechain does plan to reward its validators with XRP tokens for securing that specific chain, offering a different incentive model.

How much XRP do I need to stake to become a validator?

You do not need to stake any XRP to become a validator on the main XRP Ledger. The XRPL’s consensus mechanism, the Ripple Protocol Consensus Algorithm RPCA, does not rely on a staking model where tokens are locked up as collateral. This is a significant difference from Proof-of-Stake blockchains like Ethereum, which requires staking 32 ETH to become a validator. For the main XRPL, the only “cost” in terms of XRP is the small amount of XRP required for transaction fees when interacting with the ledger, but these fees are burned, not paid to validators. If you’re interested in staking XRP for potential rewards, you might be looking at third-party staking services or the upcoming XRPL EVM Sidechain, which will have its own requirements, including potentially funding a wallet with XRP.

What are the risks of running an XRP validator?

While you don’t risk losing staked funds because there’s no staking for mainnet validators, there are still risks and responsibilities. The main risks involve operational costs and potential reputational damage. You’ll incur costs for hardware or cloud server rental, electricity, and internet connectivity, which are ongoing expenses. If your validator is unreliable e.g., frequent downtime, inconsistent agreement with the network, it may be removed from Unique Node Lists UNLs, reducing its influence. Additionally, there’s always the general risk of cybersecurity threats to your server, which could compromise your operations or, in a worst-case scenario, contribute to network instability if exploited. It’s crucial to implement strong security measures and maintain your node diligently to mitigate these risks.

How much does it cost to run an XRP validator?

Running an XRP validator primarily involves hardware/cloud rental, electricity, and internet costs. The rippled software itself doesn’t cost anything, and there are no direct XRP fees or staking requirements to operate a validator on the mainnet. Where to buy pc cases

• Hardware: If you opt for a cloud VPS, costs can range from $20-$50 per month for recommended specifications 8+ CPU cores, 64GB RAM, fast SSD. Running a physical server might involve a higher upfront investment several hundred to over a thousand dollars for robust components but potentially lower ongoing costs for electricity if efficiently managed.
• Electricity: The electricity usage is comparable to running an email server. For a dedicated server, this will vary based on your local electricity rates and hardware efficiency.
• Internet: A stable, fast internet connection 100 Mbps or more is essential and part of your regular utility bills.
  Overall, while not “free,” the costs are generally manageable, especially when compared to the high entry barriers e.g., 32 ETH or significant energy consumption of other blockchain validation methods.

Can I run an XRP validator on a home computer?

While it might be technically possible to run a basic rippled node for testing on a commodity home computer, running a reliable and influential XRP validator requires dedicated hardware or a robust cloud server that can guarantee high performance and near 100% uptime.

• Minimum Specs: Home computers rarely meet the recommended specifications 8+ CPU cores, 64GB RAM, high-IOPS NVMe SSD, gigabit network interface for a production validator.
• Reliability: Home internet connections often lack the stability, speed, and consistent uptime needed, and consumer-grade hardware is not designed for 24/7 operation.
• Security: Securing a home computer against various online threats to the level required for a public-facing validator can be challenging.
  For these reasons, using a dedicated server either physical or cloud-based is highly recommended for anyone serious about becoming an XRP validator and contributing reliably to the network.

What is the Unique Node List UNL?

The Unique Node List UNL is a list of trusted validators that each individual XRP Ledger server maintains. When a rippled server whether it’s a full node or a validator receives transaction proposals, it only considers the votes from validators that are on its own UNL. To reach consensus and finalize a ledger, a supermajority at least 80% of the validators on a server’s UNL must agree on the proposed transactions. This trust-based system is fundamental to the XRPL’s security and efficiency, preventing single points of failure and protecting against malicious actors trying to sway the network by simply running many nodes. Each server operator can customize their own UNL, though many default to lists published by trusted entities like the XRP Ledger Foundation and Ripple.
