Bitcoin Cash is a hard fork of Bitcoin with a protocol upgrade to fix on-chain capacity. Bitcoin Cash intends to be a Bitcoin without Segregated Witness (SegWit) as soft fork, where upgrades of the protocol are done mainly through hard forks and without changing the original economic rules of the Bitcoin. Bitcoin Cash (BCH) is released on 1st August 2017 as an upgraded version of the original Bitcoin Core software. The main upgrade is the increase in the block size limit from 1MB to 8MB. This effectively allows miners on the BCH chain to process up to 8 times more payments per second in comparison to Bitcoin. This makes for faster, cheaper transactions and a much smoother user experience. Why was Bitcoin Cash Created? The main objective of Bitcoin Cash is to to bring back the essential qualities of money inherent in the original Bitcoin software. Over the years, these qualities were filtered out of Bitcoin Core and progress was stifled by various people, organizations, and companies involved in Bitcoin protocol development. The result is that Bitcoin Core is currently unusable as money due to increasingly high fees per transactions and transfer times taking hours to complete. This is all because of the 1MB limitation of Bitcoin Core’s block size, causing it unable to accommodate to large number of transactions. Essentially Bitcoin Cash is a community-activated upgrade (otherwise known as a hard fork) of Bitcoin that increased the block size to 8MB, solving the scaling issues that plague Bitcoin Core today.

DERO is a new, experimental blockchain technology written in Golang with a focus on enhanced Privacy and Smart Contracts while maintaining the transparency and security of the blockchain. The goal is to create a unique state of the art blockchain technology with enhanced Reliability, Privacy, Security, Usability, and Portability by bringing together some of the best proven technologies like CryptoNote Protocol and Smart Contracts, thereby allowing for the creation of Private Smart Contracts. The Dero Project has written a unique new blockchain technology that is based on the CryptoNote protocol. Dero's goal is to create a unique state of the art blockchain technology with enhanced reliability, privacy, security, usability, and portability by bringing together some of the best proven technologies like the CryptoNote protocol and smart contracts, thereby allowing for the creation of truly private smart contracts. The Dero development team has implemented complete SSL across the Dero network which is a first on any blockchain. This encrypts the entirety of our network traffic, which greatly reduces our attack surface, while simultaneously preventing ISPs or other users from analyzing Dero’s network traffic.
