• Candidate Blocks

    Blocks created by miners in part of a proof-of-work consensus blockchain. A candidate block broadcasts its hash to check if it is valid. The wining candidate block with a valid hash then creates the next block in the network.

  • Coin Age

    A measure used in Proof of Stake networks to calculate the value of a node's holdings during a given hashing period. Coin age can be used to help gauge transaction legitimacy. Peercoin is a PoS that uses coin age to help determine which node will add a block.

  • Cold Storage

  • Cypherpunk’s Manifesto

    A paper written by Eric Huges that outlines Cypherpunks’ philosophy and vision. This Manifesto was a big influence on many early cryptocurrency enthusiasts.

  • Cypherpunks

    A network of activists that advocated for the widespread use of strong cryptography and privacy-enhancing technologies as a route to social and political change. Cypherpunks were heavily involved in the early development of Bitcoin.
