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.

MARK.SPACE is an open-source platform for the creation of 3D/VR/AR-compatible spaces and objects of any purpose, as well as their quick launch and integration into a unique ecosystem. The platform supports a crypto economy and is powered by Blockchain. MARK.SPACE supports all Internet browsers (preferably Chrome) and, at the same time, is compatible with CardBoard, Oculus and HTC Vive. A desktop PC or tablet is all that is needed to create a state-of-the-art VR store, office, community or other space for business or entertainment. The MARK.SPACE universe consists of multiple VR spaces (units), in which each unit can be linked directly to its own top-level domain. The property right to the units is guaranteed by recording all transactions involving units (creation, sale, purchase or rental) on the Blockchain. All unit owners may buy, sell or rent their units to others using smart contracts. MARK.SPACE has an internal currency - the MARK token (MRK), which is a utility token (not a paper bond), allowing all users to sell and buy VR spaces and objects, consume various goods and use services, pay salaries to their employees and to buy ads to promote their businesses through the MARK.SPACE platform. GPU-miners who will be rendering VR spaces and objects for the platform’s users will also receive rewards in MRK tokens (Proof of Work (PoW) Concept).
