Centralization Risk

Overview

Centralization risk arises when one organization or small group can control upgrades, keys, validation, transaction ordering, custody, pricing, access, or emergency actions. Concentration can improve efficiency while creating a single point of failure or coercion.

The risk may exist despite decentralized branding if users rely on one frontend, sequencer, oracle, bridge, cloud provider, stablecoin issuer, or governance bloc. Failure, compromise, collusion, censorship, regulation, or insolvency at the concentrated component can affect the wider system.

Assessment should identify actual decision rights and operational dependencies, not count nominal participants alone. Mitigations include independent operators, distributed keys, transparent governance, exit options, fallback infrastructure, limits, and credible processes for replacing failed or malicious parties.

Centralization risk is the exposure created when critical authority, infrastructure, data, liquidity, or decision-making depends on too few parties. Centralization risk depends on who can actually control or interrupt critical functions, not simply how many visible participants exist.

For Centralization Risk, the assessment should evaluate the exposure created when critical authority, infrastructure, data, liquidity, or decision-making depends on too few parties. The assessment record should separate observed evidence supporting the exposure created when critical authority, infrastructure, data, liquidity, or decision-making depends on too few parties from assumptions, state the time horizon and existing controls, and identify who owns any remaining exposure. Monitoring should test whether the conditions described in the exposure created when critical authority, infrastructure, data, liquidity, or decision-making depends on too few parties have changed enough to require a new rating, treatment, or approval.

Decision-makers should use findings about the exposure created when critical authority, infrastructure, data, liquidity, or decision-making depends on too few parties to select treatment, assign remediation, set review thresholds, and document why any residual exposure is accepted.
