Security for the Metaverse: Blockchain and Machine Learning Techniques for Intrusion Detection
Bibliographic record
Abstract
Considered to be the next-generation (NextG) Internet, the Metaverse faces various security risks inherited from its predecessor and new specialized threats. It is even more challenging to mitigate these issues in a large-scale setting with numerous wearable devices such as augmented, virtual reality (AR/VR) headsets. In this article, we aim to analyze the security aspect of the Metaverse thoroughly, focusing on blockchain and machine learning (ML) solutions. Firstly, we present a 4-layer architecture of the Metaverse and discuss potential solutions for Metaverse security based on blockchain and ML. Next, we develop a decentralized collaborative intrusion detection system (CIDS) based on blockchain and federated learning (FL) that allows such the Metaverse users to collaboratively protect this digital world. This helps solving the scalability and single-point-of-failure (SPoF) issues of traditional security approaches. Finally, we outline some key challenges and discuss future research directions for Metaverse security.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
