Editing Digital currency (section)

=== Digital versus cryptocurrency ===
[[Cryptocurrency]] is a sub-type of digital currency and a digital [[asset]] that relies on [[cryptography]] to chain together [[digital signature]]s of asset transfers, [[peer-to-peer]] networking and [[decentralization]]. In some cases a [[proof-of-work]] or [[proof-of-stake]] scheme is used to create and manage the currency.<ref name="ars1">{{Cite web |url=https://arstechnica.com/business/2013/05/wary-of-bitcoin-a-guide-to-some-other-cryptocurrencies/ |title=Wary of Bitcoin?
