The basic service provided by cryptography is the ability to send. For each request, the server sends the client a freshly generated random challenge r and and a difficulty parameter n, and the client has to produce a solution s …. With symmetric cryptography, the same key is used for both encryption and decryption. More generally, people think of cryptography as the art of mangling information into apparent unintelligibility in a manner allow-ing a secret method of unmangling. Confidentiality Confidentiality is the fundamental security service provided by cryptography.

Is there any cryptocurrency where mining is profitable - Quora

The cryptocurrency profitability depends on a lot of factors, such as equipment cost, your hardware hash rate, power consumption, and the current Bitcoin price (or, for altcoin mining, the current price of that altcoin relative to Bitcoin). The early days of Bitcoin mining are often described as a gold rush. Miners, in turn, get a small reward (a fraction of the cryptocurrency being mined) for their contribution to the blockchain network. CryptoCompare needs javascript enabled in order to work.
