A cryptocurrency transaction is usually a rapid and straightforward process. Bitcoin, for example, can be exchanged between digital wallets using only a smartphone or computer. Public and private keys and various incentive schemes such as proof-of-work and proof-of-stake are used to safeguard these transfers. Payments in cryptocurrencies are growing more popular among large corporations and in industries such as fashion and pharmaceuticals.

Mining computers compile valid transactions into a new block and attempt to generate the cryptographic link to the previous block by finding a solution to a complex algorithm. When a computer succeeds in generating the link, it adds the block to its version of the blockchain file and broadcasts the update across the network.
Altcoins also sometimes differ in the method of verification used to authenticate transactions. While some altcoins use Proof-of-Work systems, others use Proof-of-Stake consensus, which replaces miners with validators. Proof-Of-Stake mining requires a lot less energy and fewer resources than Proof-Of-Work systems since Proof-Of-Work miners have to do much more ‘work’ to mine blocks.
