With just one line
Bitcoin miners can now participate in the Core DAO validator election process without changing the mining method or allocating computing power resources between the two networks. This mechanism is called delegated proof of work (DPoW) and is a core component of the Core Network Satoshi Plus consensus system.
When Bitcoin miners want to delegate proof of work to the Core network, they simply add data in the op_return field of the Coinbase transaction, specifying the Core verifiers to support and the address to receive the CORE reward. This operation is done during the Bitcoin block mining process, so miners do not have to make a trade-off between protecting the Bitcoin network and the Core network.
The design is designed to achieve mutual benefit: Bitcoin miners receive a second block reward by receiving the CORE token reward, while the Core network benefits from Bitcoin's security and decentralized infrastructure. This additional reward stream does not require any additional calculation, and the economic logic is very clear for miners who are already operating on a large scale.
How to calculate the validator score
In each round, the Core network counts the number of blocks generated by each miner on the Bitcoin network on the same day a week before, thereby calculating the Bitcoin computing power associated with each validator. This computing power value is combined with the other two inputs to generate the final ranking.
The validator selection for the Core Network follows a structured multi-stage process based on the Satoshi Plus consensus. The consensus integrates delegated proof of workload (DPoW), delegated proof of equity (DPoS), and self-custodial Bitcoin pledges into a unified hybrid scoring system. At the end of each round, the verifiers are ranked based on a mixed score, and the top 27 verifiers with the highest scores will be selected into the set of verifiers for the next round.
As Bitcoin block rewards decrease over time, the CORE reward stream provides miners with an additional source of income to compensate for their activities on the Bitcoin and Core networks. For mining pools that want to diversify their revenue without increasing operational burdens, DPoW provides a low-threshold entry point that allows them to easily enter the Core ecosystem.
