important notes
- The Starknet Foundation has awarded Alpen Labs a grant to accelerate the development of shared validation tools for the broader Bitcoin ecosystem.
- Glock technology uses garbled circuitry and claims to reduce on-chain verification costs by up to 1000 times compared to previous models such as BitVM.
- This initiative aims to unlock use cases for BTCFi, such as native staking and borrowing, without relying on less secure wrapped assets or multisig setups.
Starknet is working with Bitcoin BTC $110,904 24 hour volatility: 0.4% Market capitalization: $2.21 trillion Vol. 24 hours: $7.765 billion Research firm Alpen Labs builds a highly secure, trust-minimized bridge that connects two networks.
The partnership, confirmed on October 15, aims to give native Bitcoin holders access to advanced decentralized finance (DeFi) features directly on the Starknet platform.

A new security model to protect Bitcoin
This effort moves away from traditional bridging models that often result in significant security vulnerabilities.
According to details in the project announcement and technical whitepaper, many existing solutions rely on trusted multi-signature setups, which can allow signers to collude and steal funds.
To get around this, Glock uses a two-party calculation protocol based on garbled circuitry. This design allows for complex validation without revealing private inputs from either chain, eliminating the need for a trusted intermediary.
Starknet’s strategy to become a Bitcoin hub
The partnership is a key part of Starknet’s stated commitment to Bitcoin expansion, a plan first detailed in March 2025 as part of the broader “BTCFi on Starknet” initiative.
To further this goal, the Starknet Foundation awarded Alpen Labs a grant to develop and audit a shared Glock validator intended to become a public good for the broader Bitcoin ecosystem.
This push is supported by a 100 million STRK incentive program designed to encourage development on the network. Alpen Labs claims that its technology is highly efficient, with certain Glock25 variants achieving over 430-550x efficiency compared to models such as BitVM2.
The new bridge allows users to stake and borrow Bitcoin without having to wrap their assets, and the announcement received a positive response from the cryptocurrency community.
The development comes as the broader Bitcoin market weathers turmoil. The ecosystem recently experienced significant drawdowns highlighted by market volatility that led to liquidations of over $19.35 billion.

Despite these challenges, institutional investor belief appears to remain, as exemplified by Strategy Inc.’s ongoing corporate accumulation of 220 BTC.
