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.

Nimiq is a browser based blockchain. It was written in Javascript ES6 and because of this, the complete blockchain runs in the browser. The main goal of Nimiq is to solve the payment solution, and to provide a browser based payment solution of sending money. They also have nearly instant transactions as well. Nimiq is a CPU only mineable coin, since it uses the Aragon2D algorithm. Nimiq intends to lower barriers of entry for blockchain technology, and make it accessible for mainstream use. With an operational betanet already live, users can experience how simple it is to mine inside a browser - installation free. Nimiq is making blockchain technology as accessible as the internet, with a vision to truly decentralize the web. Current available cryptocurrencies are complicated and counterintuitive for the average person to use. True internet decentralization is impossible if access to blockchain technology is limited to only the technically oriented people. Until blockchain can be picked up with general recognition and general usage, its true power remains unrealized. Nimiq originally began as an ERC20 (Ethereum) token, known as NET or Nimiq Exchange Token. Nimiq held its ICO throughout June and July of 2017, and raised over 10 million USD. NET trading was enabled shortly after the ICO, and development began on the project’s Github. NET was converted to NIM, the currency that is based on the Nimiq blockchain and network, on March 31st of 2018. Nimiq’s wallet (Nimiq Safe) is built right into the Nimiq website, which means there is no need to download or sync a wallet application. The wallet will lead you through a setup guide, which will help backup and secure your wallet in the case of data loss. As the Nimiq wallet is based in the browser, however, erasing your cache could delete your balance – so keeping a backup is highly recommended.
