# Cryptocurrency > **Machine-Evolution Nexus:** [[articles/Digital Darwinism and the Invisible World of Machine Evolution|Digital Darwinism and the Invisible World of Machine Evolution]] provides the evolutionary and computational context for this supporting concept. **Domain:** Distributed Systems / Economics **Doc Type:** Supporting Canonical Node **Maturity:** Developed ## Definition Cryptocurrency is digitally represented value transferred and accounted for through cryptographic protocols and distributed consensus. ## Nexus Context Bitcoin, Ethereum and their forks create technical lineages whose persistence depends on software, validators, markets and communities rather than biological reproduction. ## Markets as an application of computational inference [[wiki/The Alan Turing Institute|The Alan Turing Institute]] supplies a concrete adjacent token-market example: its [2021 NFT study](https://www.turing.ac.uk/blog/non-fungible-tokens-can-we-predict-price-theyll-sell) examined price patterns using machine learning, transaction history, and trader-network information. [[wiki/Convergence Research|Convergence Research]] places market modeling beside other uses of inference and prediction, and keeps high-frequency execution and the funding of future machine infrastructure as separately specified questions. NFTs and cryptocurrencies occupy different roles within the wider token economy. ## Relationships [[wiki/Blockchain|Blockchain]], [[wiki/Bitcoin|Bitcoin]], [[wiki/Ethereum|Ethereum]], [[wiki/Technological Evolution|Technological Evolution]] ## Sources / Provenance - Developed from the cited research in the central article and the surrounding continuity, rights and evolutionary architecture.
