# Core Features of sBTC

sBTC offers several core features that make it a powerful trust-minimized Bitcoin bridge between Stacks and Bitcoin:

{% step %}
**1:1 Bitcoin Backing**

Each sBTC token is backed by an equivalent amount of Bitcoin in the peg wallet. This ensures that sBTC maintains a stable value relative to BTC.
{% endstep %}

{% step %}
**Decentralized Management**

The sBTC peg wallet is maintained and managed by a set of sBTC signers. This decentralized approach enhances security and reduces single points of failure.
{% endstep %}

{% step %}
**Quick Conversions**

sBTC facilitates rapid movement between BTC and sBTC:

* BTC to sBTC conversion can be completed within 3 Bitcoin blocks
* sBTC to BTC conversion can be completed within 6 Bitcoin blocks
  {% endstep %}

{% step %}
**SIP-010 Compatibility**

sBTC adheres to the SIP-010 fungible token standard on the Stacks blockchain. This ensures wide compatibility with Stacks wallets and applications.
{% endstep %}

{% step %}
**Community Governance**

The initial sBTC signing set is determined by a community vote, weighted by STX holdings. This approach ensures that the community has a say in the management of the sBTC system.
{% endstep %}

{% step %}
**Signer Key Rotation**

sBTC signers have the ability to rotate their private keys, enhancing long-term security of the system.
{% endstep %}

{% step %}
**Transaction Fee Sponsorship**

sBTC transactions on Stacks can be sponsored, allowing users to pay transaction fees in sBTC instead of STX.
{% endstep %}
{% endstepper %}
