That cryptographic proof comes in the form of transactions that are verified and recorded on a blockchain. A blockchain is an open, distributed ledger that records transactions in code. With a blockchain, everyone who uses a cryptocurrency has their own copy of this book to create a unified transaction record. Software logs each new transaction as it happens, and every copy of the blockchain is updated simultaneously with the new information, keeping all records identical and accurate.
To prevent fraud, each transaction is checked using one of two main validation techniques: proof of work or proof of stake. Cryptocurrencies typically use either proof of work or proof of stake to verify transactions. The first computer to do so successfully is rewarded with a small amount of cryptocurrency for its efforts.
This race to solve blockchain puzzles can require an intense amount of computer power and electricity. In practice, that means the miners might barely break even with the crypto they receive for validating transactions, after considering the costs of power and computing resources. To reduce the amount of power necessary to check transactions, some cryptocurrencies use a proof of stake verification method. To discourage fraud, if you are chosen and verify invalid transactions, you forfeit a part of what you staked.
Both proof of stake and proof of work rely on consensus mechanisms to verify transactions. This means while each uses individual users to verify transactions, each verified transaction must be checked and approved by the majority of ledger holders.
