Metronome (MET) was launched in 2017 and claims to be the first self-governing, “cross-blockchain” cryptocurrency. It aims to be the dominant cryptocurrency used across a multitude of blockchains and is “built-to-last”The team behind the project believes that mass blockchain cryptocurrency adoption requires a currency that is not tied specifically to one blockchain but is rather compatible with any and all. As such, Metronome follows three fundamental principles that it believes can help it to achieve its goals. These are self-governance, reliability, and portability.What are Metronome’s key features and how does it work?As touched upon, Metronome has three core design principles. Metronome’s functions and its MET token are governed by four smart contracts. These are Ledger, Auction, Proceeds, and Autonomous Converter.Self-governance is reflected in the project by the fact that the founders of Metronome have no control of the system after launch. Governance is managed by a community of users, via autonomous smart contracts. Also, there is public access to all sale opportunities, Reliability is another fundamental principle. MET is designed to have a low but continuous issuance rate, i.e. steady and predictable token supply via descending price auctions. The Metronome team specifically did so as they believe it will mean MET behaves more like a FIAT currency, and in turn, hopes that its users will use it as one.Metronome’s portability is achieved through its ability to move between blockchains. What is noteworthy about Metronome?Through Metronome’s focus on multi-chain compatibility, the project hopes to increases its adoption and long-term prospects. Metronome is also unique for the fact that its payment feature allows subscriptions. Users can set up recurring payments between themselves and other parties through a set of smart contracts. What can Metronome be used for?Metronome states that it was designed for use cases that hold reliability at the center of its needs. Possible use cases include:Payment Settlement (Mass Pay allowing users to send tokens to more than one address in one action, and subscriptions allowing users to set up recurring payments easily and reliably).Decentralized store of value.Metronome also expects its communities and other institutions to “discover their own use for Metronome”, as such the MET token has potential to be used in across a variety of sectors.
