What is Heavycoin?

Heavycoin introduces a novel ultra-secure hashing algorithm that employs multiple redundant cryptographic hash functions to secure its block chain. Bitcoin and most other crypto-currencies rely on a single cryptographic hash function, such as SHA-256. Heavycoin aims to improve security by following the old adage of not putting all the eggs in the same basket.
