Protocols are vital components of Blockchain technologies that enable information to be shared across cryptocurrency networks reliably and securely. In the field of computing, protocols are necessarily rules that define how information and data are allowed to be transferred between various computer systems. Protocols define the way that data should be structured to be accepted into a computer system, and they create safeguards to prevent malicious users from causing damage. Protocols for Blockchain are similar as they enable server nodes to exchange data over the internet that all network systems can understand.
