A Block Creator is an entity that generates new blocks in a blockchain. These blocks contain transaction data that is grouped together based on a specific time frame. In proof-of-work systems, block creators are often referred to as miners. They compete to solve complex mathematical puzzles to validate transactions.

The first to solve the puzzle adds the new block to the blockchain and is rewarded with cryptocurrency, incentivizing them to participate in the network. In proof-of-stake systems, block creators are selected based on the number of coins they hold or are willing to “stake.” This method is more energy-efficient, as it does not require intense computational power.

Successful block creators in this model earn transaction fees or newly minted coins as a reward. Overall, block creators play a crucial role in maintaining the security and integrity of the blockchain, ensuring that transactions are verified and added in a trustworthy manner. Their efforts prevent double-spending and maintain the shared ledger that users rely on.
