Denarius' cryptographic hashing algorithm, Tribus, is ASIC resistant, and consists of three of the most secure and popular cryptographic algorithms. Denarius is named after a Roman coin that was widely used during the peak of the Roman Empire.

Bitcoin Cash is a cryptocurrency that was created as a result of a hard fork of the original Bitcoin blockchain that took place in 2017. Due to the open source nature of the Bitcoin protocol, and the lack of a central governing body to resolve disputes, the Bitcoin community became extremely divided about what to do about rising fees and slow transaction times. As the platform's transaction volume increased, and the associated fees to confirm them also increased dramatically, many people began advocating for a larger block size.
In mid 2017, a group of developers introduced segregated witness technology, or SegWit, that was designed to increase Bitcoin's scalability by moving some transaction details off of the blockchain. Segwit was meant to resolve the issues that revolved around the growing amount of transaction data, but many members of the Bitcoin community felt that it undermined the original vision outlined by Satoshi Nakamoto.
On August 1, 2017, they initiated a hard fork of the protocol that created Bitcoin Cash and implemented an increased block size of 8mb. At the time of the fork, bitcoin holders automatically became owners of the same number of Bitcoin Cash units. The increased block size led to faster transaction times and made Bitcoin Cash easier to use as a medium of exchange.
