Transactions are grouped into blocks.
Miners (computing nodes) validate transactions and add blocks to a public ledger called the blockchain.
Miners who successfully add blocks are rewarded (with newly minted Bitcoin + transaction fees).
The blockchain ensures transparency, immutability, and prevents double-spending.
Mining is the process by which network participants (miners) solve cryptographic puzzles to validate transactions and create new blocks. It’s how new bitcoins are introduced and how network security is maintained.
