Core Chain

Stake Core with Kiln, enterprise-grade staking

What is Core Chain? 

Core Chain is a Bitcoin-powered, EVM-compatible Layer 1 blockchain with smart contracts that enables BTC staking, a feature traditionally unavailable to Bitcoin holders. Core Chain uses a Delegated Proof of Work mechanism that mixes dPOS-derived economic security and rehypothecated Bitcoin Mining power and is managed by the CoreDAO.

How is Core Chain implemented?


Core Chain uses the Ethereum Virtual Machine (EVM) for its execution environment. Core Chain has a BTC bridge enshrined into the protocol, which locks BTC on Bitcoin to mint coreBTC on Core Chain. 

In the minting process of coreBTC, users send BTC to a Locker's Bitcoin address, which is then monitored by Porter to submit transaction proof to the Core Chain smart contract, allowing for verification via the Bitcoin Light Client and subsequent minting of equivalent coreBTC tokens.

In the protection phase of coreBTC, Lockers deposit overcollateralized assets, with Liquidators monitoring and enforcing liquidation if collateral levels fall, using coreBTC to purchase Locker's tokens at a discount and burning coreBTC in the process, while Guardians oversee Lockers for misbehavior, penalizing violations by slashing collateral and burning equivalent coreBTC.

In the burning phase of coreBTC, users request the burning of coreBTC, specifying a Bitcoin address, triggering the smart contract to burn the coreBTC tokens and notify the Locker, who then sends the equivalent BTC to the user's address, with the transaction verified by the Bitcoin Light Client.

Why should you stake your assets?

Staking offers a secure and reliable method to earn rewards from your digital assets. These rewards come from both the native currency inflation of the blockchain and/or a portion of transaction fees. With Core Chain, the rewards are distributed via the Core Token. It has a total supply of 2.1 billion, to be distributed through block rewards over 81 years.

You can stake your Core Chain to:
  • Earn Core Token
  • Put your treasury to work
  • Bring new opportunities by enabling your users to earn staking rewards

CoreDAO FAQ

What does Delegated Proof of Work (DPoW) mean?

plus

Delayed Proof of Work (dPoW) is a consensus algorithm that merges the features of both Proof of Work PoW and dPoS. Learn more here.

When will I receive CORE rewards?

plus

You will receive the first reward after 48 hours, followed by subsequent rewards every 24 hours thereafter.

Does interest compound when staking CORE?

plus

For now, CoreDAO doesn’t have a built-in compound interest mechanism.

Is there a minimum and maximum amount to stake for CORE?

plus

There is no minimum amount to stake CORE.

Do I maintain custody of my CORE tokens? Is CORE staking non-custodial?

plus

While you may maintain self-custody of your staked CORE (ideally using a Ledger hardware wallet), you may also choose a third-party custodian to control the withdrawal of your staked CORE (i.e. Fireblocks).

What is the lockup period to stake CORE? When can I unstake and withdraw my CORE?

plus

You can unstake and withdraw your tokens at any time, you will receive them instantly.

What are the risks associated with staking CORE?

plus

A validators can be slashed from accrued rewards should it fail to mine 50 blocks in a row. If it fails to mine 150 blocks in a row it can be slashed by 10% of the tokens delegated and be jailed for 3 days, meaning it won't be able to mine blocks during this time.

How do rewards and penalties work on Core Chain?

plus

Rewards come from the fees paid on the CORE chains and the emissions of the CORE token. Stakers will earn a yield on their staked CORE.

What is the average block time on Core Chain?

plus

The average block time on Core Chain is 3 seconds.

What is a Gross Reward Rate (GRR) and how is it different from a Net Reward Rate (NRR)?

plus

In the context of staking blockchains, the gross reward rate (GRR) refers to the total or gross amount of rewards earned from staking before deducting any fees or expenses. This is a reward rate that fluctuates with the operations of the protocol and the performance of validators, it is not set by Kiln. The net reward rate (NRR), on the other hand, takes into account the deductions or expenses, providing a measure of the actual rewards received after subtracting fees or costs.

Where can I learn more about CoreDAO?

plus

You can learn more about CoreDAO on their official white paper.

Gross Reward Rate (GRR) may change over time and vary depending on the open source blockchain protocol code. In addition, fees might be deducted from the gross effective rewards earned.
