blastmarket.io is built on transparency, verifiable data, and automated resolution to ensure every market settles fairly and accurately.

​
How we ensure fairness

Immutable market terms: Once a market goes live, nothing can be changed. Resolution criteria, data sources, dates, and all parameters are permanently locked at creation. This prevents manipulation by creators, the platform, or any third party.
Market odds change constantly as users react to new information. The price displayed may be different from the price at execution.

​
Public resolution criteria

Every market displays its exact resolution criteria before you trade. You know precisely:
  • What conditions trigger a YES outcome
  • What conditions trigger a NO outcome
  • Which data source will be used for verification
  • When and how the resolution will occur
No hidden rules. No subjective interpretation.

​
Oracle-based resolution

Markets resolve using predetermined data sources:
  • Tier 2 markets: Automated via Chainlink oracles with real-time data feeds
  • Tier 3 markets: Verified using public data sources specified at market creation
The outcome is determined by objective, publicly accessible data, not by BLAST or the market creator.

​
24-hour dispute window

After every resolution, a 24-hour dispute period allows the community to challenge incorrect outcomes. If a market resolves incorrectly due to a data error or misapplication of criteria, users can dispute and trigger a review process.

​
How we ensure accuracy

​
Tier-based validation

Every market is evaluated for verifiability and data quality before going live:
  • Tier 0 (Rejected): Markets vulnerable to manipulation are automatically rejected
  • Tier 1 (Rejected): Markets without reliable data sources are rejected
  • Tier 2 (Approved): Data-rich markets with robust oracle feeds
  • Tier 3 (Approved): Verifiable markets with limited but reliable data sources
This pre-approval process filters out ambiguous, unverifiable, or manipulable markets before they can mislead users.

​
AI-powered market creation

BLAST AI analyzes every market question to:
  • Identify the most reliable data source
  • Generate clear, objective resolution criteria
  • Flag ambiguous or subjective phrasing
  • Suggest optimal resolution timing
This reduces creator error and ensures markets are structured for accurate settlement from the start.

​
Post-resolution verification

All resolutions are on-chain with a reference to the data source used. You can independently verify that:
  • The correct data source was consulted
  • The resolution criteria were applied accurately
  • The outcome matches publicly available information

​
Community accountability

Market creators: Earn fees based on volume, incentivizing them to create clear, accurate, high-quality markets that attract informed users. Dispute system: Any user can challenge resolutions they believe are incorrect, ensuring community oversight and accountability.

​
What fairness means in practice

  • You always know the rules before you trade
  • The rules cannot change after you trade
  • Outcomes are determined by objective data, not opinions
  • You have recourse if something goes wrong
  • All settlements are transparent and verifiable on-chain
blastmarket.io doesn’t decide who wins or loses. The data does.
