Primecoin is a rather interesting digital currency. It was developed by Sunny King, one of the same developers that created PPCoin and invented Proof-of-stake. Primecoin does not follow the same rules as the other currencies, and has a built in mathematical benefit. Due to the way it is mined, Primecoin actually discovers previously unknown prime numbers.

Primecoin does not follow the same rules as the other currencies, and has a built in mathematical benefit. Due to the way it is mined, Primecoin actually discovers previously unknown prime numbers. The innovative prime proof-of-work in Primecoin not only provides security and minting to the network, but also generates a special form of prime number chains of interest to mathematical research. Thus primecoin network is energy-multiuse, compared to bitcoin network. Primecoin is designed to sustain a prosperous mining market and high level of security, while maintaining good scarcity property like gold. Primecoin also processes payment transactions 10x faster than bitcoin network. All in all, Primecoin presents itself as an extremely interesting experiment; for the first time, we have a currency whose mining algorithm has a secondary value, and at the same time Primecoin, unlike so many other coins before it, actually makes serious attempts to improve on Bitcoin in unrelated aspects. Not taking into account Bitcoin’s massive headstart, Primecoin may well be the first alternative coin to actually be better than Bitcoin, giving the currency the potential for a bright future ahead.
Tripio is the first travel marketplace based on the blockchain. It leverages the decentralized network provided by blockchain technologies to directly connect global customers and service providers. Moreover, it builds a service ecosystem based on transparent, tamper-resistant trust and incentives. The blockchain technologies Tripio leverages help reduce transactional and operational costs in travel industries, as well as improve customer experience in their respective products and services. On the Tripio platform, a service provider can publish her unique service terms and conditions using smart contracts. From the moment a purchase initiates to the end of the travel, every step along the way can be enforced and monitored by smart contracts. Should disputes arise, Tripio provides dispute resolution by means of community selfgovernment mechanisms. Tripio comprises of its dApps and a set of Tripio Protocols that forms the basis of the new ecosystem. The Tripio dApp and the Tripio Protocals are powered by the ERC-20 utility token called the TRIO token. Customers may use Tripio dApps directly. At the same, any third-party may build its own dApp by leveraging the open Ethereum protocols.
