Beldex announced a plan to introduce verifiable random functions (VRFs) in a 2026 mainnet hardfork, but the available official sources do not confirm that the upgrade activated. The proposal would use verifiable pseudorandom outputs to help select consensus participants and a block producer. Beldex presents less predictable selection and faster finality as intended benefits, not independently measured results.
What is a VRF?
A verifiable random function produces an output using a secret key and a corresponding proof. The secret-key holder computes the output; other people can use the associated public key and proof to check that it was generated correctly. As RFC 9381 puts it, “A Verifiable Random Function (VRF) is the public key version of a keyed cryptographic hash.” RFC 9381, published by the IRTF’s Crypto Forum Research Group in 2023, is informational rather than an Internet Standards Track specification.
In a consensus design, this gives participants a way to check a selection value without trusting the node that produced it to report the value honestly. A VRF is a cryptographic primitive, however, not a complete consensus protocol: its security depends on choosing a suitable construction and generating keys correctly.
How is Beldex proposing to use VRFs?
In its January 28, 2026 announcement, Beldex describes its existing consensus as using a fixed 11+1 arrangement, with 7 of 11 nodes required to approve a proposed block. Those figures describe Beldex’s account of its own system; they are not a general rule for proof-of-stake networks.

The proposed flow would have eligible masternodes calculate pseudorandom output values and submit proofs. Nodes whose values fall below a threshold for that round would be eligible to produce a block, and the node with the lowest valid output would be selected as producer. Other participants could verify the output using its proof. This is the proposal as Beldex describes it, not confirmation of deployed behavior. Beldex’s announcement
Why is Beldex adopting VRF-based consensus in 2026?
Beldex says the proposed design is intended to make validator selection less predictable, broaden participation beyond its described fixed quorum, reduce coordination overhead, and reach finality faster by requiring fewer intermediary rounds. The cited material does not provide independent measurements showing that these outcomes have been achieved, nor does it establish how performance would compare under defined network conditions.

How many nodes would participate?
Beldex’s pages give two examples that do not agree in proportion. The January 2026 announcement illustrates approximately 1,200 participants out of 1,800 nodes—about two-thirds. A separate Beldex explainer says that at most 666 of 2,000 nodes participate—about one-third. The pages do not explain whether these describe different subsets or revisions, so neither figure should be treated as a settled protocol parameter. Beldex’s VRF explainer
What a VRF proof does—and does not—guarantee
A valid proof allows others to verify that an output corresponds to the VRF computation for a public key. That does not, by itself, make a consensus protocol unbiased, immune to manipulation, Sybil-proof, quantum-resistant, or invulnerable to a 51% attack. RFC 9381 distinguishes properties such as uniqueness, collision resistance, pseudorandomness, and unpredictability; the construction and key-generation process matter to the security the system actually provides.

The Beldex materials cited here do not include an independent security analysis of the proposed implementation. Assessing its guarantees would require details of the deployed construction, key handling, eligibility threshold, and consensus rules, along with analysis of how those parts work together.

The reviewed official sources do not establish activation. Beldex’s January 2026 post described VRF consensus as a planned change for a scheduled 2026 mainnet hardfork. Its roadmap lists “VRF hardfork release” under Q1 2026 as “Planned.” The Beldex explorer snapshot for October 4, 2026 identifies mainnet Hard Fork v21 and Beldex Version 7.0.3-release, but does not say that VRF consensus is active. A release note, consensus-code change, or explicit activation notice would be needed to verify deployment.
