How Does Crypto Mining Work?

Explanation of blockchain technology

Blockchain technology serves as the underlying infrastructure for cryptocurrencies, enabling decentralized and transparent peer-to-peer transactions. Each block in the blockchain contains a list of transactions that must be validated by miners before being added to the ledger.

Role of miners in validating transactions

Miners play a crucial role in maintaining the integrity of the blockchain by independently verifying the accuracy of transactions. Through a process known as consensus, miners collectively agree on the validity of new blocks, ensuring that no single entity can manipulate the ledger.

Mining algorithms and hardware

Different cryptocurrencies employ varying mining algorithms, each with its own set of requirements and rewards. For example, Bitcoin utilizes the SHA-256 algorithm, while Ethereum relies on Ethash. Miners must invest in specialized hardware tailored to their chosen algorithm to maximize their mining efficiency.
