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.

Skychain is an open infrastructure, based on blockchain, which provides the possibility to create, train and use high-quality medical neural networks. IBM estimates the artificial intelligence market in the healthcare sector to reach $200 billion in a few years. Skychain’s goal is to control more than 70% of that market! The way to achieve this goal is to create the best open infrastructure that will accumulate the resources of the majority of participants of this industry and surpass any closed corporate product. The mission of Skychain is to save 10 million patients from premature death due to medical errors within 10 years. Medical errors are the third leading cause of death, but artificial intelligence can dramatically reduce the number of such errors! Skychain intends to provide an infrastructure to radically increase the efficiency of healthcare AI development and training. It will make diagnostic AI systems far more accessible and affordable for the consumer by using blockchain technologies to facilitate safe transactions between the key parties. Skychain is unique. The project is based on the revolutionary approach of using smart contracts to bring together many healthcare big data providers whose data is vital for AI training, thousands of independent AI developers, computational resource providers (crypto miners), and millions of consumers.
