Which blockchains can you actually mine?
TBB separates true mining from staking and validator operation, then compares the practical entry barriers of mineable networks.
Ease of Entry, not profitability.
TBB's Participation Ease score uses the same formula for every chain: 25% hardware barrier, 20% existing TBB accessibility, 20% capital barrier, 15% setup complexity, 10% energy burden and 10% operator openness. It does not estimate token returns, mining profit, staking yield or investment merit.

TBB keeps the terms honest.
Bitcoin and Centronium are represented as mineable because work is performed to earn block/mining rewards. Proof-of-stake networks are described as staking, validating, delegating, baking or node operation instead of being mislabeled as mining.
No fabricated dollar entry prices.
Where a protocol publishes a fixed requirement, TBB states it. Where the requirement is dynamic, elected or dependent on hardware/stake markets, TBB publishes a barrier class and explanation instead of freezing a misleading dollar estimate.
