A validator node is a special type of full node that participates in “consensus.” By participating in consensus, validator nodes become responsible for verifying, voting on, and maintaining a record of transactions. On the Babylon Mainnet version of the Radix Public Network, there is a maximum of 100 validator nodes at a time. These are selected based on the amount of stake XRD token holders have delegated to them.
Validator nodes underpin the security of any blockchain or DLT network. That is why it is of vital importance to ensure that validator nodes remain both performant and trustworthy.
For Radix, it is vitally important that you, as an XRD token holder, support the security of the network by selecting the best validators to stake to.

Now, let's delve into the concepts mentioned in the provided article on the Radix Public Network, specifically focusing on "Validator Nodes" and related terms:
-
Validator Node:
- A validator node is a specialized type of full node within a blockchain or distributed ledger technology (DLT) network.
- Validator nodes play a crucial role in the consensus process, where they are responsible for verifying, voting on, and maintaining a record of transactions.
- On the Babylon Mainnet version of the Radix Public Network, there is a maximum of 100 validator nodes at a given time.
- The selection of validator nodes is based on the amount of stake XRD token holders have delegated to them.
-
Consensus:
- Consensus is the process by which nodes in a distributed network agree on the state of the system, particularly regarding the order and validity of transactions.
- Validator nodes participate in the consensus mechanism to achieve agreement on the blockchain's state.
-
XRD Token:
- XRD is the native token of the Radix Public Network.
- Token holders can delegate their XRD tokens to validator nodes to participate in the consensus process and support the security of the network.
-
Security of Blockchain or DLT Network:
- Validator nodes are fundamental to the security of any blockchain or DLT network.
- The article emphasizes the importance of ensuring that validator nodes remain both performant and trustworthy to maintain the overall security of the Radix Public Network.
-
Staking:
- XRD token holders can stake their tokens by delegating them to validator nodes.
- Staking is a mechanism that aligns the interests of token holders with the security and integrity of the network.
-
Radix Public Network:
- The Radix Public Network is a blockchain network utilizing the Babylon Mainnet version.
- It relies on a set of validator nodes for achieving consensus and securing the network.
-
Related Reading:
- The article suggests further reading on topics such as how validators are selected on Radix, the concept of a full node, the definition of a validator set, and guidance on running a validator on the Radix network.
In conclusion, the provided article emphasizes the critical role of validator nodes in the Radix Public Network, highlighting their significance in ensuring the security and reliability of the blockchain. This information is crucial for XRD token holders who aim to actively participate in and contribute to the network's consensus mechanism.
FAQs
Validator definition: Node in a proof-of-stake blockchain network responsible for validating transactions and maintaining consensus. A validator is a participant in a blockchain network tasked with confirming transactions and adding them to the blockchain.
How many validators are there in Radix? ›
At the beginning of each epoch, the Radix Protocol will automatically select the 100 validator nodes with the most delegated stake to become the validator set. This stake is the sum of both self-stake and delegated stake.
What is the difference between validator nodes and full nodes? ›
In blockchain and crypto, Validator nodes are what most people think of as a node. These are nodes that are part of that blockchain's validator set and are responsible for validating transactions in consensus with the other validator nodes in the validator set. Full nodes do not conduct consensus.
What is a validator set? ›
A group of validators that are responsible for directly participating in the consensus of a blockchain through either voting, producing, or proposing blocks.
What is a validator? ›
Validators are the operators running each of these independent nodes. These node operators are responsible for running the chain software, validating transactions, proposing new blocks, and ensuring the integrity and security of the network.
How do you become a validator node? ›
How to become a Validator. Becoming a validator requires access to high-performance hardware on a highly available network, as minimum 300 000 TON as a stake. Validators stake Toncoin for a fixed specific term, and the stake is refunded with interest after the completion of a validation round.
Is radix a blockchain? ›
Radix is a blockchain that allows people to create their own decentralized applications. XRD is the native token of Radix, a blockchain that helps people create decentralized finance applications.
What is a radix range? ›
In the number system, the radix or base is the number of distinct digits, including the digit zero, used to represent numbers in a positional numeral system. For instance, the radix (base number) for the decimal system, which is currently the most popular system, is ten since it employs the ten digits from 0 to 9.
Is radix stable or not? ›
It is not an in-place sorting algorithm because it requires extra space. Radix Sort is a stable sort because it maintains the relative order of elements with equal values.
What's the difference between a node and a validator? ›
Validator Nodes accept “writes” to the blockchain, processing and adding user transactions to the ledger. But Full Nodes primarily focus on “reads,” handling user queries and offering scalability to the validators by distributing read request loads.
Stakers are rewarded for helping to validate the ledger. They do this by delegating their stake to validator nodes. Those validators do the legwork of replaying the ledger and send votes to a per-node vote account to which stakers can delegate their stakes.
What are the main components of a validator node? ›
Validator node components
- Mempool Mempool is a component within each node that holds an in-memory buffer of transactions that have been submitted to the blockchain, but not yet agreed upon or executed. ...
- Consensus ...
- Execution ...

A validator is an individual or a group responsible for running software that stores data, verifies transactions, and adds new blocks in a proof-of-stake (PoS) blockchain. Validators are replaced by miners in a proof-of-work (PoW) blockchain.
What is a validator code? ›
A validation code is an extra layer of security that protects customers from fraud when making payments online or over the phone.
How is a validator selected? ›
Under proof-of-stake (POS), validators are chosen based on the number of staked coins they have. Proof-of-stake (POS) was created as an alternative to proof-of-work (POW), the original consensus mechanism used to validate transactions and open new blocks.
How much do validator nodes make? ›
The average ETH staking APY is roughly 4% for validators that do not utilize MEV-Boost. Validators with MEV-Boost enabled average roughly 5.69%.
What is an ETH validator node? ›
Validators are the backbone of the Ethereum PoS consensus mechanism. Their primary role is to participate in the consensus process by proposing and validating blocks of transactions. To become a validator, an individual must stake a certain amount of Ethereum (ETH) as collateral.
