# Base Calculations

Introducing Stroom's Mainnet Point Program - a specially crafted system designed to reward Stroom protocol users. By engaging with `strBTC` (Stroom BTC) — a BTC Liquid Staking Token (LST) that operates across the Ethereum DeFi ecosystem — you earn Stroom points, which make you eligible for certain benefits that will be announced later. 

The Point Program will consist of three phases: soft launch, native staking, and economic security. Each phase will introduce dynamic bonuses and point multipliers that will change over time. Keep an eye on this article's changes, and you will always be up to date with the terms of point accrual. 

## Phase 0 – Soft Launch

Duration: August 5, 2025 – Now

Key elements:

* No native BTC via Stroom bridge: Users deposit `wBTC` and receive `strBTC` via an immutable converter contract that performs the `wBTC` <-> `strBTC` conversion on-chain
* First DeFi integrations for `strBTC`
* Available at [app.stroom.network/convert](https://app.stroom.network/convert)

#### Point Accrual

Stroom points represent the number of owned `strBTC` and can be increased with different multipliers.&#x20;

**Stroom Points = strBTC × ΔEthereum Block Height + DeFi Bonuses**

* <sub>strBTC — Amount of owned strBTC</sub>
* <sub>ΔEthereum Block Height — Number of Ethereum blocks that the address holds strBTC</sub>
* <sub>DeFi Bonuses — Additional points you can earn for using strBTC on specified DeFi protocols</sub>

**Point Leaderboard**

Your total number of points will be available via the [app.stroom.network/leaderboard](https://app.stroom.network/leaderboard) on the Mainnet tab. Points are refreshed every 24 hours.
