Validators

Libre Chain validator node information.

The Libre chain is secured by its decentralized network of validators. These validator nodes are independently owned and located all over the world.

Libre Node Map as of April 2025

Libre validator nodes provide APIs for submitting transactions, chain history for wallets and applications, as well as validation of blocks for which validators are paid.

Validators are paid for each block on the Libre chain that they produce. There is a halvening schedule for block pay which occurs on a superblock. A superblock happens every 15,768,000 seconds.

Initially, validators were paid 4 LIBRE per block and there will be 2 halvenings, one at 6 months and one at 12 months. The block rewards have a terminal rate of 1 LIBRE per block.

Types of Libre Network Nodes

The Libre ecosystem consists of three main types of nodes, each with different functions and requirements:

1. API Nodes

• Function: Serve API requests, provide chain history, and relay transactions

• Difficulty: Easy to set up and maintain

• Requirements: Basic server hardware with sufficient storage

• Rewards: None directly, but they support applications built on Libre

• Ideal for: Application developers, service providers, and community members

2. Validator Nodes

• Function: Produce and validate blocks, maintain consensus, serve APIs

• Difficulty: Moderate to set up, requires ongoing maintenance and monitoring

• Requirements: Higher-grade hardware, reliable connectivity, 24/7 operation

• Rewards: Block production rewards in LIBRE tokens

• Ideal for: Dedicated operators with infrastructure experience

3. CrossLink Nodes

• Function: Validate and process cross-chain transactions between Bitcoin and Libre

• Difficulty: Advanced, typically operated alongside validator nodes

• Requirements: High-performance hardware, dedicated Bitcoin node

• Rewards: Transaction fees in multiple currencies:

  • BTC fees from validating Bitcoin peg-in/peg-out transactions

  • USDT fees from processing stablecoin transfers

• Ideal for: Existing validators seeking additional revenue streams

Most CrossLink operators also run validator nodes, enhancing both the security of the Libre network and the cross-chain bridge while maximizing rewards through multiple fee sources.

For detailed information on running a CrossLink node, see the Libre CrossLink documentation.

You can learn about the existing nodes by visiting these websites:

All validators must review the Libre Governance Docs - which outline the minimum requirements and responsibilities.
