Designed from scratch for storing, managing, and issuing digital assets, Waves (WAVES) is an open source decentralized blockchain platform that enables anyone to create their own internal digital currencies. Building on approaches implemented by NXT to make adding new transaction types possible, WAVES approaches this practice via plug-ins that do not require an update to the core software, but instead may be installed as extensions on top of it. As a result, clients not running software with these additional plug-ins may still relay custom transaction types without the need to support a mandatory hard fork of the core code.
