Blockchain is a trustful machine that is connected to crypt economic and the application of that is the Bitcoin. This is connected to bitcoin and enable peer-to-peer (P2P)- of the people, to the people, for the people, to use that.
To perform transactions on the blockchain, it is necessary a wallet- a program that store and exchange bitcoins and is protected by a cryptographic method. If a message is encrypted with a specific public key, only the owner of the paired private key will be able to decrypt and read the message. On the other way, if you encrypt a message with your private key, only the paired public key can be used to decrypt it.
This system incentives the people use blockchain and keep the network secure.
