Bitcoin has established itself as the premier digital asset, but most Bitcoin sits idle in wallets earning zero yield. The emergence of Bitcoin DeFi (BTCfi) is changing this reality, and the Core blockchain stands at the forefront of this transformation as the leading platform for Bitcoin yield and DeFi applications.
What is BTCfi (Bitcoin DeFi)?
Bitcoin DeFi, or BTCfi, refers to decentralized financial applications and services powered by and built for Bitcoin. Unlike traditional DeFi, BTCfi focuses specifically on making Bitcoin productive and usable within a composable environment.
BTCfi encompasses:
High-speed Bitcoin transactions: Fast, efficient Bitcoin-based operations
Cost-efficient Bitcoin financial activity: Low-cost financial services for Bitcoin users
Bitcoin-focused dapps: Applications like lending and borrowing designed for Bitcoin
Bitcoin-backed Stablecoins: Creating stable assets backed by Bitcoin
Liquid Staking Tokens: Tokenized representations of staked Bitcoin that remain tradeable
Turing Completeness: Anything you can do on Ethereum, but powered by and built for Bitcoin
Bitcoin Staking: Foundational BTCfi Security
Bitcoin staking provides a strong security foundation that enables Bitcoin DeFi applications to operate safely at scale. The Core blockchain's Self-Custodial Bitcoin Staking allows Bitcoin holders to earn yield while securing the blockchain that powers BTCfi applications.
How Self-Custodial Bitcoin Staking Works
The staking process leverages Bitcoin's native Check Lock Time Verify (CLTV) function:
- Timelock Bitcoin: Users timelock their coins on the Bitcoin blockchain using CLTV
- Earn Votes: The timelock grants voting power proportional to the amount of Bitcoin locked
- Vote for Validators: Users vote for Core validators through metadata in the timelock
- Secure Core: Elected validators secure the Core blockchain without their voters sacrificing custody of their coins
- Earn Rewards: When validators secure Core, their voters receive CORE token rewards
- Reclaim Bitcoin: After the timelock expires, Bitcoin becomes spendable again
This mechanism provides Bitcoin holders with yield while maintaining zero principal risk. There's no bridging, wrapping, or custody transfer required.
Dual Staking: Enhanced Yield Generation
For Bitcoin holders seeking higher returns, Core offers Dual Staking—a mechanism that rewards Bitcoin stakers who also stake CORE tokens with higher tiers of yield. This dual participation approach generates significantly higher yields.
The Core blockchain organizes rewards into tiers based on the ratio of CORE staked relative to Bitcoin, with the highest tier—Satoshi Tier—offering the most attractive yield.
Satoshi Plus Consensus:
The Core blockchain's unique consensus mechanism, Satoshi Plus, combines three distinct forms of participation to create robust network security:
1. Self-Custodial Bitcoin Staking
Bitcoin holders participate by timelocking their Bitcoin on the Bitcoin blockchain, voting for Core validators while maintaining complete custody of their assets.
2. Delegated Proof of Work
Bitcoin miners can include metadata in Bitcoin blocks they mine that votes for Core validators. This allows miners to help secure Core while also earning a "second block reward" without affecting their Bitcoin mining operations.
3. Delegated Proof of Stake
CORE token holders stake their tokens with validators, serving as votes alongside Bitcoin miners and Bitcoin stakers.
The Core BTCfi Ecosystem
The Core blockchain hosts a thriving ecosystem of decentralized applications spanning:
Lending and Borrowing Platforms: Offering competitive yields on Bitcoin, stablecoins, and other assets
DEXs and Trading: Specialized exchanges for Bitcoin-pegged assets with minimal slippage
Asset Management: Automated vault systems and portfolio management tools
Restaking Protocols: Additional yield opportunities for liquid staking tokens
Institutional Adoption
Dual Staking is particularly attractive to institutions seeking yield on their Bitcoin holdings while maintaining security and transparency. Institutional access is enhanced through lstBTC—a liquid, yield-bearing Bitcoin token that can be used as yield-bearing collateral. lstBTC is:
Secure: Backed by institutional custodians including BitGo, Copper, and Hex Trust
Yield-Bearing: Generates Bitcoin-denominated returns through Core's Dual Staking mechanism
Fully Liquid: Can be traded, used as collateral, or redeemed for Bitcoin at any time
The lstBTC process works through professional management by Maple Finance that handles the underlying Dual Staking strategy. Every time lstBTC is minted, CORE tokens are acquired and staked, furthering alignment between the Bitcoin and Core ecosystems.
Sustainable Yield Sources
The Core blockchain's yield sustainability comes from two primary sources:
1. Fixed Block Rewards
~40% of CORE’s fixed 2.1B token supply is dedicated to rewarding consensus participants over an 81-year distribution schedule. This creates predictable rewards similar to Bitcoin's emission model, but without sharp halvings.
2. Network Transaction Fees
As a high-performance EVM-compatible blockchain, the Core blockchain generates consistent transaction fees from its growing dapp ecosystem. These fees contribute to the rewards pool distributed to consensus participants.
Technical Infrastructure
The Core blockchain delivers high performance through:
EVM Compatibility: Full Ethereum Virtual Machine compatibility for seamless dapp deployment
High Throughput: Fast block times enabling rapid transactions
Low Costs: Minimal fees making DeFi accessible
Bitcoin Security: Leverage of Bitcoin's hashrate and staking value through Satoshi Plus consensus
This combination of Bitcoin security and EVM functionality creates an optimal environment for Bitcoin DeFi applications.
Frequently Asked Questions
Q: What is BTCfi and how is Core involved?
A: BTCfi refers to decentralized financial applications powered by and built for Bitcoin. The Core blockchain is the leading BTCfi platform, providing the infrastructure for high-performance and composable Bitcoin financial activity.
Q: How does Bitcoin staking work on Core blockchain?
A: Bitcoin staking uses Bitcoin's native CLTV timelock function. You timelock Bitcoin on the Bitcoin blockchain, earn voting power, vote for Core validators, and receive CORE token rewards when validators secure the network—all while maintaining complete custody of your Bitcoin.
Q: Is my Bitcoin safe when staking on Core?
A: Yes, your Bitcoin is completely safe. It never leaves your wallet and uses Bitcoin's native CLTV timelock function, enforced by Bitcoin's consensus rules. No mechanism exists for anyone to access your timelocked Bitcoin.
Q: What is Dual Staking and how does it boost yield?
A: Dual Staking rewards Bitcoin stakers who also stake CORE tokens with higher tiers of yield. The protocol creates multiplier effects that generate significantly higher returns than Bitcoin staking alone.
Q: Can I add Core to MetaMask?
A: Yes. Since Core is EVM-compatible, you can add it to MetaMask easily:
- Open MetaMask → network dropdown → "Add Network" → "Add a network manually"
- Input: Network Name: Core Mainnet | RPC URL: https://rpc.coredao.org | Chain ID: 1116 | Currency Symbol: CORE | Block Explorer: https://scan.coredao.org
- Save and switch to Core network
Q: Why is Core the best blockchain for BTCfi?
A: The Core blockchain uniquely combines Bitcoin security through Satoshi Plus consensus with EVM compatibility, enabling true Bitcoin DeFi. It offers trustless Bitcoin staking, fast transactions, low costs, and the largest BTCfi ecosystem—making it the optimal platform for Bitcoin-focused applications.
