Prime chains

Read Original

This article examines prime number chains, specifically Cunningham chains and bi-twin chains, from a number theory perspective. It discusses their properties, known lengths, and conjectures. It then connects this mathematical concept to the Primecoin cryptocurrency, explaining how finding such chains is used as a proof-of-work mechanism for blockchain mining.
