Start Accepting Haypenny in Minutes
Haypenny is a digital currency like no other because it's as close to physical cash as you can get in the digital realm. It requires no wallet (just like cash), and you possess the value contained in the currency purely by virtue of your possessing the block string exclusively.
At the heart of the Haypenny model is the unique "block-split-combine" paradigm, which starts with the very simple concept of a block: a secret string ("block string") which is connected to a balance.
API Concepts
For developers, the Haypenny model is easy to learn, and is exposed through three REST APIs with the following parameters:
Language-specific APIs
Haypenny maintains APIs for the most popular development environments. These modules also contain example code and quick-start information as well:
- JavaScript: hblock-1.0.2.js (see also: client-only JavaScript examples).
- Java: HBlock.java
- PHP: hblock.lib.php (see also: PHP Paywall Example)
- C: hblock.h
You can also view all of Haypenny's APIs in a web UI using the Haypenny API Tester.
Read the Whitepaper
The Haypenny Platform Whitepaper provides formal description the of Haypenny system in a single document. The Haypenny platform was built from the start to handle all of the world's daily transactions and has been benchmarked at over one million transactions per second while securely storing every transaction in a decentralized data store.
The Sandbox
Development can be performed on the Haypenny sandbox site, which can be safely used for testing (although doing your testing on the live site is fine too since there are no transaction fees and you can work with very small amounts).
