Hedera for Music Streaming Micropayments

The Hedera Hashgraph Network



Idea Inception

While at Brown University, Andrew Antar started Musicians@Brown, a student group for musicians to collaborate with each other, jam, and form bands. Upon its initial success on campus, Andrew began designing a music social network and recruiting Brown's top engineering talent. Meanwhile at University of Pennsylvania, Brian Antar was producing beats for local rap/hip-hop artists and recording sessions at Penn Studios. Upon searching for ways to independently distribute tracks while retaining full control, Brian saw it didnt exist and decided to create a direct-to-fan music marketplace where artists can control their pricing and distribute music directly to their fans. Once the brothers realized they were both simultaneously creating music platforms, they combined their ideas and efforts to create the ultimate global social music marketplace platform for artists and fans to share their music.

As the platform scaled up, made significant investments into its uncompressed audio file conversion technology to be able to upload and stream thousands of large original master files seamlessly.


A Token Idea

With the constant challenges of running a fiat marketplace with banks and credit cards, the founders felt that in order to truly fulfill their full vision for, they needed a way to fully tokenize the marketplace to enable micropayments directly to artists and allow for a decentralized music economy to flourish where artists and fans can earn tokens by streaming and curating music. The founders embarked on a search to find the best distributed ledger technology and cryptocurrency software platform available to enable micropayments and tokenization of the marketplace.
