On November 19, 2024, the Core Foundation announced the official launch of the Fusion upgrade. As the largest Bitcoin DeFi ecosystem today, this revolutionary upgrade of Core aims to introduce two innovative products: Core Dual Staking and Core LstBTC, further integrating Core with Bitcoin and enhancing the decentralized financial value of BTCFi.
“With the full rollout of Fusion, Core will increase the profitability of Bitcoin staking, making the Bitcoin decentralized finance ecosystem more scalable and providing more opportunities for users to earn income,” said Rich Rines, an early Core contributor. “Fusion provides greater scalability and earnings opportunities. It will improve the current Core staking user experience and even attract more participants who want to earn sustainable returns in the BTCFi space.”
The Fusion upgrade introduces two key features to enhance the staking experience: dual staking , which is now available, and LstBTC, which will be launched soon.
1. Double Staking
Double staking is a revolutionary breakthrough for Bitcoin stakers, enabling them to earn higher returns. Double staking increases BTC staking rewards for Bitcoin and CORE token stakers.
2. LstBTC - Liquidity staking token pegged 1:1 to BTC
LstBTC is an ERC-20 liquidity staking token that is pegged 1:1 to Bitcoin (BTC). This innovation allows BTC holders to receive CORE token rewards daily while maintaining Bitcoin liquidity, providing a solution to the long-term choice between staking and liquidity in the DeFi field.
Sustainable staking and superior scalability
The Fusion upgrade enables Core to maintain its leading position in the Bitcoin staking economy, especially in terms of further performance improvement in sustainable returns. The introduction of dual staking and liquid staking tokens not only increases returns, but also ensures the scalability of the network.
Core continues to lead the charge in Bitcoin staking, having launched the first non-custodial Bitcoin staking protocol with over 7,600 BTC staked since April 2024. As the only end-to-end BTCFi solution, Core offers both Bitcoin staking products and Bitcoin-secured smart contracts. In addition to staked Bitcoin and CORE, the Core blockchain is secured on-chain by the hashrate of Bitcoin miners – delegating hashrate to earn CORE token rewards to offset the decline in Bitcoin’s block subsidy. Currently, Core has delegated ~75% of Bitcoin’s hashrate to on-chain validators. With over 100 EVM-compatible dApps, Core is positioned as the #1 Bitcoin scaling chain, supporting tens of thousands of daily active users and over $650M in TVL, secured by Bitcoin miners and stakers. The upcoming “Dual Staking” and “LstBTC” products further solidify Core’s dominance, linking CORE and Bitcoin together in a more sustainable way.
