Blockchain
Originally powering Bitcoin, blockchain transcends its origins. This digital ledger thrives on data batches called blocks that are distributed across countless computers, a strategy that ensures security through decentralization. To tamper with it is futile, as altering data necessitates changing copies on every computer—a security strategy that works on safety in numbers.

To add a block, a computer cracks a puzzle, signaling readiness to the network, which is a process known as proof of work. Once accepted, a new block joins the chain. Information from the blockchain, a trusted and distributed public ledger, assures accuracy.
