@Coredao_Org has built a mechanism that lets $BTC holders participate in validator elections without transferring their coins off the Bitcoin network. The process relies on CheckLockTimeVerify (CLTV), a Bitcoin-native scripting opcode that has been part of the protocol since 2015. CLTV is a Bitcoin script operation that restricts transaction outputs from being spent until a specified absolute time or block height is reached. No bridging, wrapping, or third-party custody is involved.
By creating a transaction with a CLTV script, Bitcoin holders can make their coins temporarily unspendable while including metadata that allows Core to recognize their participation in consensus. That metadata specifies which validator the holder wants to support and the address where $CORE rewards should land. The Bitcoin itself never leaves the holder's wallet.
Delegating Bitcoin for staking rewards through Core's self-custodial product does not require any asset transfers or bridging onto the Core blockchain or to validators. Even if the validators or the Core blockchain go down, users' assets remain in their complete custody and can be redeemed after the timelock expires on the Bitcoin network.
Once a timelock transaction is broadcast, relayers scan the Bitcoin network for those locks, read the embedded validator choice, and update election weights on Core accordingly. When a Bitcoin holder stakes with Core, they participate in the election of Core validators. When a staker's designated validator is elected, it helps secure the Core blockchain in exchange for $CORE token rewards, which are then largely allocated back to the Bitcoin stakers that elected it.
The timelock grants voting power proportional to the Bitcoin amount locked. More Bitcoin staked means more influence in validator selection. Rewards scale accordingly and stop when the lock expires. Core's documentation is explicit that there is no auto-renewal: after the lock period ends, Bitcoin becomes spendable again, and to continue staking, users must create a new timelock.
Staking constitutes two-thirds of Core's Satoshi Plus consensus, enabling both Bitcoin and $CORE token holders to help secure the network and earn rewards. For long-term holders who prefer to stay on the Bitcoin blockchain, the model offers a way to put idle capital to work without introducing new trust assumptions.
