# Staking

Stacks Dual Stacking allows participants to earn **Bitcoin-denominated rewards** through **Proof-of-Transfer (PoX)**, the consensus mechanism that secures the Stacks network. Bitcoin committed to Dual Stacking accrues BTC rewards, which may be enhanced by holding STX or by deploying BTC within the Stacks DeFi ecosystem.

{% hint style="success" %}
hBTC qualifies for the **maximum 10x Dual Stacking reward tier** by deploying into DeFi.
{% endhint %}

Proof-of-Transfer rewards have been active since 2021, with **over 3,740 BTC distributed** to participants since inception.

Dual Stacking rewards are distributed to the vault contracts on a bi-weekly basis and are smoothed into the vault’s daily NAV through prorated accounting (1/14 per day). All sBTC rewards are redeployed into active DeFi strategies and automatically compounded.

Historically, base Dual Stacking rewards have ranged between 0.3%–0.5% APY. By qualifying for the maximum 10x Dual Stacking tier, hBTC benefits from an enhanced reward rate, historically equivalent to approximately **3%–5% APY**.
