DJCoin, or DJC, is a cryptocurrency for the dance music community. So, what is a cryptocurrency?
As the name suggests, cryptocurrencies are born out of cryptography. This is the ability to encode information so that only parties with the relevant permissions can unlock and decipher that information. The unlocking, as you would expect, is done with keys which are contained in wallets.
Cryptocurrencies use public key cryptography. You need a private key to send money and a public key to receive money. All transactions of cryptocurrencies are recorded publicly on the blockchain.
