Core is an EVM-compatible Layer 1 that aligns with Bitcoin through its unique Satoshi Plus consensus mechanism — Bitcoin miners can delegate their hash power to Core validators without redirecting it from Bitcoin mining, earning CORE rewards for what is essentially free additional income. This non-custodial Bitcoin staking model creates a bridge between Bitcoin's security and smart contract functionality. The key innovation is that Bitcoin miners don't need to change their operations at all. They continue mining Bitcoin normally and simply signal their support for Core validators — it's additive, not competitive with Bitcoin mining. This means Core can tap into Bitcoin's enormous hash rate for security signaling without diluting Bitcoin's own security. Core also offers non-custodial BTC staking where Bitcoin holders can earn yield while keeping BTC on the Bitcoin network. Core positions itself in the emerging "BTCfi" (Bitcoin DeFi) sector — the movement to bring DeFi capabilities to Bitcoin holders without requiring them to trust bridges, wrapped tokens, or leaving the Bitcoin network. By letting BTC holders earn yield natively, Core addresses Bitcoin's biggest criticism: that it's a non-productive asset.
Core DAO launched the Core blockchain in early 2023, founded by Rich Rines. The Satoshi Plus whitepaper proposed the novel consensus mechanism combining Bitcoin PoW delegation with PoS. Non-custodial BTC staking launched as the flagship product for Bitcoin holders. Core attracted attention as the BTCfi narrative gained momentum in 2024, with billions in Bitcoin delegated to the network.
Satoshi Plus consensus combines Delegated Proof of Work (from Bitcoin miners) with Delegated Proof of Stake (from CORE stakers). Bitcoin miners include metadata in their coinbase transactions signaling their preferred Core validator — no additional computation required. CORE stakers delegate to validators normally. Both groups earn CORE rewards proportional to their contribution. Non-custodial BTC staking uses time-locked Bitcoin transactions that earn CORE rewards without transferring BTC to Core's chain.
CORE has a maximum supply of 2.1 billion tokens (a nod to Bitcoin's 21 million). Block rewards are distributed to validators based on combined DPoW and DPoS contributions. CORE is used for transaction fees, staking, and governance. A portion of transaction fees is burned, introducing deflationary pressure.
Satoshi Plus lets Bitcoin miners earn additional rewards without changing their operations — non-competitive with Bitcoin.
Bitcoin holders earn yield without bridges, wrapping, or leaving the Bitcoin network.
Full Ethereum tooling support for developers building DeFi on Core.
First-mover in the Bitcoin DeFi narrative with a novel technical approach.
Satoshi Plus combines multiple mechanisms — harder to analyze security guarantees than pure PoW or PoS.
Needs sustained Bitcoin miner delegation and BTC staking to maintain security and value proposition.
Stacks, Babylon, and other Bitcoin L2/sidechain projects compete for the same BTCfi narrative.
Core's dApp ecosystem is smaller than Ethereum, Solana, or established L2s.
You create a time-locked Bitcoin transaction that signals your support for a Core validator. Your BTC never leaves the Bitcoin network — it's locked in your own address with a time constraint. During the lock period, you earn CORE rewards. When the lock expires, your BTC is fully accessible again. No bridges, no wrapping, no counterparty risk.
No — Bitcoin miners continue mining Bitcoin normally. They simply include a small piece of metadata in their coinbase transaction that signals their preferred Core validator. No hash power is diverted from Bitcoin mining. It's purely additive — miners earn extra CORE rewards for essentially zero additional cost.
Both are Bitcoin-adjacent smart contract platforms, but with different approaches. Stacks uses Proof of Transfer (burning STX for BTC rewards) and anchors directly to Bitcoin blocks. Core uses Satoshi Plus (Bitcoin miner delegation + PoS) and offers EVM compatibility. Core has simpler developer onboarding (standard EVM tools); Stacks has deeper Bitcoin integration with Clarity smart contracts.
