BitCrystals are Counterparty assets which acts as game currency for EverdreamSoft’s upcoming mobile game Spells of Genesis (SoG) and trading card game Moonga. BitCrystals come about because the game creators believe that players should be able to keep their game assets outside the control of game developers' databases and like a normal economy, allow for free trade of the virtual goods. There was a crowdsale of the BitCrystals token where 70% of the 100 million total tokens were made available for purchase. The remaining 30% were given to early supporters and contributors. All unsold BitCrystals were burned on October 2015. A total of 974.13 BTC was raised during the crowdsale.
Zen is a decentralized financial platform, built from scratch with the goal of providing people with a secure, scalable and useful infrastructure for creating their own financial instruments, and trading them directly without intermediaries.The Zen blockchain is secured by multiple proof-of-work algorithms, with token-holder voting on the balance between them. Multi-hash mining creates robust incentives for miners to deliver efficient, reliable security.Zen smart contracts are written and secured by a subset of the F* functional programming language, allowing users to: A) Prove the amount of resources a contract will consume and provide the necessary fees for running the contract to miners, removing the need for a “gas” based system.B) Prove their contracts meet a given specification, meaning they can prove the contract will definitely do (or not do) something given a specific set of parameters.The Zen platform comes with a built-in solution for oracles, which provide contracts with useful real world data.Finally, Zen is integrated with the Bitcoin blockchain, allowing contracts to observe and respond to native bitcoin transactions
