Bismuth claims to be the first Python blockchain platform that facilitates full-scale digital utility. Virtually anything can be reportedly created on Bismuth’s modular platform, ranging from simple token issuance to decentralized application (dApp) services. The entire project was created in Python, and every virtual solution built atop the platform can be done in the same language. The Bismuth protocol describes itself as an open-source, unfunded project maintained by the Bismuth Foundation and a community of Python developers
