Introduction: What is The Core Blockchain?
Launched in January 2023, the Core blockchain is a high-performance, EVM-compatible smart contract platform secured by Bitcoin, and designed for unlocking Bitcoin's potential, particularly within decentralized finance (DeFi).
Combining Features of Bitcoin and Ethereum for a Hybrid Approach
Core's hybrid architecture combines the best of both worlds:
Bitcoin's Security: Leverages Bitcoin's miners through Delegated Proof of Work and the Bitcoin asset’s value through a unique staking mechanism
Ethereum's Functionality: Full EVM compatibility enables smart contracts and DeFi applications
Interoperability: Seamless connection between Bitcoin and the broader DeFi ecosystem
Key Differentiators from Other Blockchains
What sets Core apart from other Layer 1 blockchains:
- Self-Custodial Bitcoin Staking: Bitcoin holders can stake without transferring custody of their assets
- Satoshi Plus Consensus: A novel consensus mechanism combining Delegated Proof of Work (DPoW), Delegated Proof of Stake (DPoS), and Self-Custodial Bitcoin Staking
- Bitcoin Integration, Not Competition: Core complements Bitcoin rather than competing with it. Bitcoin miners can earn additional rewards through Delegated Proof of Work, Bitcoin holders can earn yield through Self-Custodial Bitcoin Staking, and the DeFi ecosystem benefits from Bitcoin's security and network effects.
- Sustainable Economic Model: Core's yield is real, live, and liquid, stemming from transaction fees and a fixed 81-year emission schedule rather than unsustainable yield farming or points. This creates long-term sustainability for both the network and its participants.
Core's Architecture Deep Dive
Satoshi Plus Consensus Mechanism
Satoshi Plus represents a breakthrough in consensus design, combining three distinct elements:
1. Delegated Proof of Work (DPoW) Bitcoin miners can delegate their hash power to Core validators without affecting their Bitcoin mining operations. This creates a symbiotic relationship where:
Miners earn additional rewards from Core
Core gains security from Bitcoin's hash power
No changes required to Bitcoin's protocol
2. Delegated Proof of Stake (DPoS) CORE token holders can stake their tokens to validators, participating in network governance and earning rewards. This provides:
Economic security through staked value
Democratic validator selection
Aligned incentives for network participants
3. Self-Custodial Bitcoin Staking Bitcoin holders can stake their Bitcoin without transferring custody:
Bitcoin remains in users' wallets
Staking occurs through time-locked transactions
Self-ownership maintained throughout the staking period
Bitcoin Security Integration
Core's integration with Bitcoin introduces many security enhancements, including:
Hash Power Delegation: Bitcoin miners contribute computational power to Core's security without compromising their Bitcoin mining operations. This creates a security multiplier effect where Core benefits from Bitcoin's massive hash rate.
Economic Security: By enabling Bitcoin staking, Core adds an economic security layer valued in the billions of dollars. This makes attacks prohibitively expensive.
Decentralization Inheritance: Core's validator set has to earn votes from three different decentralized delegations: Bitcoin mining hash power, staked Bitcoin, and staked CORE.
EVM Compatibility Layer
Core's Ethereum Virtual Machine (EVM) compatibility opens doors for developers and users:
Full Solidity Support: Developers can deploy existing Ethereum smart contracts without modification. Popular protocols can easily expand to Core, bringing their user base and liquidity.
Familiar Tooling: All standard Ethereum development tools work seamlessly:
MetaMask wallet integration
Hardhat and Truffle frameworks
Web3.js and Ethers.js libraries
Block explorers and analytics tools
Gas Efficiency: Core's optimized architecture provides lower transaction costs compared to Ethereum mainnet, making DeFi accessible to more users.
