On-chain mining refers to the process by which transactions are verified and added to a blockchain. Miners use their computational power to solve complex mathematical problems, competing to create the next block in the chain. When a miner successfully solves a problem, they validate a block of transactions and broadcast this block to the network.
As a reward for their work, the miner receives newly created cryptocurrency and transaction fees from users whose transactions are included in the block. This process is crucial for maintaining the blockchain’s integrity and security, as it prevents double-spending and ensures that all transactions are legitimate.
On-chain mining occurs directly on the blockchain, differentiating it from other methods such as off-chain solutions, which may involve transactions recorded outside the main chain. The entire process is transparent and relies on a consensus mechanism, usually proof-of-work, where the majority of network participants agree on the validity of the transactions. This decentralized approach enhances security and fosters trust among users.
