Dagger

'Dagger' is a term commonly associated with Ethereum's mining algorithm called 'Ethash'. Ethash is a proof-of-work algorithm used by Ethereum and some other cryptocurrencies for securing their networks and validating transactions. The term 'Dagger' specifically refers to the initial step of the Ethash algorithm.

In the Dagger step, a large data set called the 'DAG' (Directed Acyclic Graph) is generated. This DAG is used in combination with a hashing function to determine the mining solution. The DAG is recalculated periodically, typically every 30,000 blocks in Ethereum, to prevent the development of specialized mining hardware and to maintain a more decentralized mining ecosystem.

Overall, 'Dagger' is a component of the Ethash mining algorithm, specifically referring to the generation and use of the DAG in the mining process.
