Sia is a decentralized cloud storage platform similar in concept to Dropbox and other centralized storage provider where instead of renting storage space from a centralized entity, clients rent storage space from other peers. The only difference is Sia uses blockchain to facilitate transactions Nodes provide storage to clients using the Sia blockchain as contracts. Before storing the data, the data is encrypted into many pieces and uploaded to different hosts. Siacoin is created by David Vorick and Luke Champine of Nebulous Inc. As the traditional storage platforms are higher in cost, more expensive and data is not well protected. Siacoin promises to offer secured storage transactions with smart contracts which is more affordable and reliable. Moreover, it is completely open source which means many individuals have contributed to Siacoin’s software hence there will be an active community building innovative applications on top if the Sia API. In 2018, Siacoin aims to introduce file sharing and be the go-to cloud storage platform for companies. Their goal is divided into 3 time frames which are short-term, medium-term and long-term development. Short-term development focuses on file sharing between Sia users. This allows Sia users to share files in the platform without having to take it off the cloud while increasing network utilization. Medium-term development’s goal is to enhance partnerships. This means reaching out to large companies like Netflix and Dropbox to hopefully be able to be their storage and distribution framework. Lastly, long-term development aims to expand its horizon to share files with non-Sia users and support mobile wallets.
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.
