Ethereum Classic vs Primecoin
What problem does this service solve?
| Ethereum Classic (ETC) is the original version of the Ethereum protocol that was maintained after the hard fork that took place in 2016. Ethereum Classic also aims to be a general purpose blockchain, but the majority of developers prefer the new fork of Ethereum, and most of ETC's on-chain activity is primarily speculative. | Primecoin uses prime number generation to improve Bitcoin's PoW protocol. |

Company Description
Ethereum Classic is the original protocol of Ethereum. As a result of the massive hack on the Ethereum-based DAO, in which around 14% of all ETH in circulation were stolen, a hard fork was proposed to return the stolen funds to their owners. This caused an ideological split revolving around the question of changing previous transactions in the blockchain. Some Ethereum holders rejected the hard fork, and decided to keep using the original protocol, based on the principle that the blockchain is immutable, and cannot be changed. | Primecoin is a cryptocurrency based on finding prime numbers. Identifying prime numbers plays a central role in cryptography. Primecoin's unique Proof-of-Work (PoW) consensus mechanism is able to increase transaction speeds and improve energy efficiency. |
