Briefing

The paper addresses the persistent ambiguity in defining and measuring blockchain decentralization by proposing a novel, stratified methodology. This framework dissects the system into eight distinct layers → from hardware and network to consensus and governance → allowing for a unified, granular analysis of centralization risks at each stratum. The most important implication is the introduction of a formal, consistent tool, the Minimum Decentralization Test, which shifts the field from subjective decentralization claims to objective, multi-dimensional security and stability metrics.

Context

Prior to this research, the concept of decentralization in blockchain systems was highly contested and often reduced to a single aspect, such as consensus participation or node count. This prevailing theoretical limitation resulted in subjective claims and a lack of a consistent, multi-faceted framework to holistically assess how centralization risk in one layer, such as hardware or economics, could compromise the entire system’s foundational properties like safety and liveness.

Each conduit culminates in a cluster of clear, ice-like crystalline particles, set against a soft grey background

Analysis

The core idea is an eight-layer stratification of a blockchain system → hardware, software, network, consensus, economics, client API, governance, and geography. By examining each layer, the methodology isolates specific centralization risks that threaten distributed ledger properties. This fundamentally differs from previous approaches by providing a unified method for measuring decentralization across all relevant components. The framework culminates in the practical Minimum Decentralization Test (MDT) , which quickly identifies “problematic” centralized layers that cause a system to fail its decentralization potential.

Parameters

Number of Layers → 8 – The total number of strata (hardware, software, network, consensus, economics, client API, governance, geography) used to dissect a blockchain system for comprehensive decentralization analysis.
Key Security Properties → 4 – The properties (safety, liveness, privacy, stability) that are examined at risk due to centralization in each layer.

Outlook

This new stratified methodology establishes a rigorous foundation for future protocol design, enabling developers to identify and mitigate centralization vectors across the entire system stack, rather than focusing solely on the consensus layer. In the next 3-5 years, this framework will likely become the standard for formal security audits and regulatory assessments, unlocking new research avenues focused on optimizing decentralization across the economic and governance layers.

Verdict

The stratified methodology formalizes decentralization from a subjective claim into an objective, multi-dimensional security and architectural metric.
