Hashcash was developed by Adam Back after he had worked on another peer-to-peer networking technology, called Openspark. Hashcash, on the other hand, is designed to be able to fit into a wide range of existing networks. It was designed by taking advantage of certain characteristics of certain standard broadcast protocols (like IP), without making them overly complicated. One of the features of Hashcash that makes it special is that it can be deployed using a standard software application, while at the same time being fully compatible with various IP networks and file formats. Hashcash is essentially designed around two principles: Hash functions utilizing hash codes, and that these functions are exclusive.

Hashcash basically refers to a proof-of-work scheme, which was originally developed by Adam Back at the start of 1997. However, since its inception, many other people have independently discovered ways to implement Hashcash on the bitcoin network and have made it available to the public. In recent times, though, the technology has also been used for the incorporation of the bitcoin network into the public internet, known as Hashcash. This has made the technology more widely available to end-users.

The main goal of Hashcash is to eliminate the need for a central server to act as an intermediary between a user’s computer and the internet, and to eliminate the risk of a central server colliding with a server containing sensitive information that is needed for a proof-of-work algorithm to be valid. By solving these problems, Hashcash enables users to run a number of nodes across the network that each performs the specific work required of each node, validating and signing the transactions. In addition, by eliminating the necessity for a central server to act as an intermediary, Hashcash reduces the overall cost of running a bitcoin node. The reduced costs have led to increased interest in the technology.
