Every transaction in Bitcoin (BTC and BCH) has a signature, (there are also those that don’t need a signature, we don’t care about these details). Signature is one thing: there is a message (mes), there is a public key (pub), and the public key corresponds to a private key (pri). Signature is to use a private key (pri) to use a specific algorithm for the message (mes) to generate a signature result Sig (pri, mes).

The free module of MOOC is an excellent introduction to cryptocurrency and blockchain. It covers business and technical information.

Monero and Zcash highlight the concept of privacy electronic currency, while Dash, based on its market-oriented strategy, highlights the concept of instant transactions, low handling fees, and global payments.
