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

  5. 5. TECHNOLOGY *Cryptocurrency transactions which do not require a transaction record, but can receive a transaction receipt.
  6. 6. *Early Access Mainnet* is coming here
  7. 7. The Hedera Hashgraph platform is ready to scale and made for developers, offering three initial services: •Cryptocurrency •Smart Contracts •File Storage Hedera Hashgraph platform
  8. 8. Hedera Cryptocurrency API Fast. 100,000+ txn/sec with finality in seconds. Fair. Ordering without manipulation. Low-fees. A fraction of a cent.
  9. 9. Core concepts • Accounts • Public key and more • Have auto-renew period (fee) • Keys & signatures • Natively multi-sig • Thresholds • Hierarchical • Receipts and records

Pay-per Blog Post Alice owns a blog ● Installs Payper Gateway ● Configures price list ● No need to change existing servers Bob is an occasional reader ● Opens an article in the browser ● Sees a Payment Required page / notification ● Uses a micro-payments wallet or browser extension to get access to the article EXAMPLE USE CASE
  16. 16. ● Verification time to zero ● API Users paid for uploading content ● Integrate with front-end components ● Other cryptocurrencies ● Potentially contribute to a standard ● GitHub ○ https://github.com/payperws Open Source Software WHERE WE’RE HEADED
  17. 17. Micro-Payments Platform ● Fast transaction confirmation ● Low fees ● Smart Contracts (for payment channels) ● Hashgraph algorithm ● Formal proofs ● Hedera Network ● gRPC / Protobuf SDK WHY HEDERA?
