Mining

Mining Mechanics

Mining is the core engine of BTB’s token economy, designed to reward long-term participation while ensuring sustainable token issuance. Mining rewards depend on three main factors: miner hashrate, total network hashrate, and the year-specific daily BTB emission schedule.

Reward Calculation Formula

BTB uses a proportional reward distribution model based on network hashrate. Each miner earns BTB according to its share of the total active mining power:

Miner Reward = (Miner Hashrate / Total Network Hashrate) × Daily BTB Emission

Rewards accumulate continuously, but the distribution is settled only when the user claims. Upon claiming, the miner’s state updates — including hashrate decay and cumulative earnings indexing — ensuring rewards reflect the exact mining period.

This design promotes fairness: miners earn rewards precisely according to their real contribution to the network at any point in time.

Linear Hashrate Decay Over 3 Years

Each NFT miner starts with a fixed initial hashrate upon purchase and follows a linear decay schedule:

• Duration: 3 years (1,095 days)

• End State: Hashrate gradually decreases to 0

• Decay Trigger:

  • Decay is only applied when the miner claims

  • Until claiming, rewards are computed based on the hashrate from the miner’s last update

This approach balances user experience and on-chain efficiency — avoiding unnecessary constant updates while ensuring accurate decay accounting.

Yearly Decay of Daily BTB Emission

The mining emission schedule decreases every year to ensure long-term sustainability and to emulate diminishing block subsidies similar to major proof-of-work networks.

Annual daily BTB emission levels:

Year	Daily BTB Emission
Y1	40,000
Y2	34,732
Y3	30,145
Y4	26,182
Y5	22,730
Y6	19,752
Y7	17,146
Y8	14,889
Y9	12,924
Y10	11,221

The declining emission curve ensures the following:

• BTB becomes increasingly scarce over time

• Early miners benefit from higher issuance

• Long-term miners still earn value due to reduced competition and decreasing supply

This combination of miner-level hashrate decay and network-level emission decay creates a balanced economy where long-term participation is rewarded while inflation reduces predictably.
