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.

Ethereum Classic is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third party interference. Ethereum Classic is a continuation of the original Ethereum blockchain - the classic version preserving untampered history; free from external interference and subjective tampering of transactions. Transaction Finality Ethereum Classic believes the core value proposition of any blockchain is immutability; valid transactions can never be erased or forgotten. Individuals interacting on Ethereum Classic are governed by this reality; Code is Law. This does not necessarily mean that code replaces existing laws, or that only code is law (there are many geographical jurisdictions), but it gives users the opportunity to enter into a new blockchain-based jurisdiction where agreements are governed by code. By entering into contracts on Ethereum Classic, you can be certain that the network remains neutral. The outcome of transactions will be dictated by code you voluntarily interact with. Unless explicitly defined by the contract code, there are no reversals, no undos, no opt-outs. Transactions are final; applications are unstoppable. Decentralized Governance There are many problems that fester due to centralization and opaqueness; corruption, unaccountability, nepotism, inefficiency and stagnation. Ultimately, centralization leads to fragility; only decentralized systems can stand the test of time. These problems can be only solved by adhering to governance systems that do not rely on a central point of failure. Just like distributed networks and the consensus protocol itself, we believe that only truly decentralized projects can survive in the long run. Ethereum Classic manifests these values by relinquishing control by a formalized central foundation. The only hierarchy is that of transparent meritocracy and mutual reputation. No backroom deals or behind-closed-doors unilateral decision making; just free and open discourse.
