# Token Supply and Issuance

<figure><img src="/files/lFRBdvUcCC0QciUoq5FC" alt=""><figcaption></figcaption></figure>

Bitcoin Solaris (BTC-S) has a fixed total supply of 21 million tokens, mirroring Bitcoin's supply model. The token distribution is as follows:

1. Initial Minting: 7 million BTC-S (33.33% of total supply)
   * Reserved for development, marketing, and ecosystem growth
2. Mineable Supply: 14 million BTC-S (66.67% of total supply)
   * To be minted through mining over approximately 90 years

Mining Schedule:

* Initial block reward: 50 BTC-S
* Halving events occur every 210,000 blocks (approximately every 4 years)
* Block time target: 10 minutes

The mining schedule follows a geometric series, similar to Bitcoin:

* First 4 years: 50 BTC-S per block
* Next 4 years: 25 BTC-S per block
* Next 4 years: 12.5 BTC-S per block
* And so on...

This halving mechanism ensures a gradual and predictable release of new tokens, promoting long-term stability and scarcity. The extended 90-year mining period is achieved through a combination of smaller block rewards in later years and potential adjustments to the halving schedule, which will be determined by network governance as the project evolves.

The dual-layer structure of Bitcoin Solaris allows for efficient distribution of mining rewards:

* Base Layer: Focuses on transaction validation and security
* Solaris Layer: Handles smart contract execution and DApp interactions

Mining rewards are distributed across both layers, incentivizing participation in all aspects of the network's operations.
