VeriCoin (VRC) is a Proof of Stake-Time cryptocurrency. It was previously a Proof-of-Stake cryptocurrency with Proof of Work used to mine coins in the early stage. VeriCoin began work on PoST after the MintPal VRC hack and the subsequent roll back. More information on Proof of Stake-Time can be obtained by reading the whitepaper here. There is no Pre-mine or IPO for VeriCoin. The minimum stake time is at least 8 hours. The one highlight feature of VeriCoin is VeriFund. VeriFund is the answer to ensure stability and growth of VeriCoin. It is used to counter the inflationary effect of the proof of stake. When the supply increases, VeriFund will purchase liquid supply of VeriCoin to ensure growth and stability of the coin's value. More info about VeriFund can be found at http://vericoin.info/verifund.html Another key feature of VeriCoin is VeriSMS. VeriSMS is an SMS wallet system that gives your phone capability to access the VeriCoin network. Some of the available commands include 'Balance', 'setpassword', and 'SEND'.

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).
