Webinar - Build a decentralized app with the Hedera Cryptocurrency API


Published on

While cryptocurrency like ether and bitcoin has been a rollercoaster of late, one thing is clear: decentralized payments can help disrupt unfair industries and create new business models. With the speed and low-fees of Hedera Hashgraph, sending a fraction of a cent can help enable new opportunities like device to device IoT payments, more secure browsing online, and more.

In this talk we'll cover:
- Disruptive micropayment use cases
- How Hedera and hashgraph make micropayments possible
- Features of the Hedera Cryptocurrency API
- Hear from the developers from the open source, cryptocurrency transactions over HTTP project Payper
