The Skycoin Platform is the most advanced blockchain platform in the world. Developed by early contributors to both Bitcoin and Ethereum, Skycoin’s platform is completely secure, infinitely scalable, and ISP independent. It uses its own specific distributed consensus algorithm, called Obelisk, instead of other commonly used algorithms like proof of work (POW) and proof of stake (POS). Obelisk uses the concept of ‘web of trust dynamics’ which distributes influence over the network and makes consensus decisions depending upon the influence score of each node. Each node subscribes to a select number of other network nodes, and the density of a node’s network of subscribers determines its influence on the network. Skycoin is very fast. With transaction speeds close to 2 seconds and no transaction fees it can rival any other cryptocurrency on the market as a payment method. The transaction costs of Skycoin are covered by Coin Hours. This is value paid to Skycoin holders for each hour they hold a Skycoin. Skycoin is against charging transaction costs and mining incentives as it only drives up the costs of the network. The biggest benefit of Skycoin is that it is energy efficient due to the Web-of-Trust social proof. It can even run on a 30-watt cell phone processor making it great for mobile payments. Centralization becomes less of an issue when anyone can participate in the blockchain. Sia stores tiny pieces of your files on dozens of nodes across the globe. This eliminates any single point of failure and ensures highest possible uptime, on par with other cloud storage providers. A major goal of Skycoin is to promote actual usage of cryptocurrency rather than speculation. Skywire, the flagship application of Skycoin, has the ambitious goal of decentralizing the internet at the hardware level and is about to begin the testnet in April. However, this is just one of the many facets of the Skycoin ecosystem. Skywire will not only provide decentralized bandwidth but also storage and computation, completing the holy trinity of commodities essential for the new internet. Skycoin also has its own ICO platform called Fiber, their own deterministic programming language, CX, derived from Golang, a private decentralized messenger system called Sky-Messenger, and a decentralized social media platform, BBS. Here is another way to think of Skycoin: An open-source, community-owned, hardware-based peer to peer internet designed from first principles and leveraging the incentive system of the blockchain.
SONM is a global operating system that is also a decentralized worldwide fog supercomputer. With SONM, users have access to general-purpose computing services of a cloud-like nature, including IaaS and PaaS, all of which have fog computing as the backend. Hosts around the world can contribute computing power as part of the SONM marketplace. The leaders of SONM are co-founder Sergey Ponomarev and CTO Igor Lebedev. SONM uses the agile development framework with a self-organizing cross-functional team. The Product Management Board defines the market needs to confirm that products meet business requirements. These include Node (Core), Smart Contracts, Wallet (Client), and Distributed Entity and Integration. Each of these teams has multiple developers, including a lead. Other teams include the Product & Analytics and QA teams.SONM always makes customer satisfaction its top priority. SONM studies the rental resource market to figure out exactly what customers need, delivering the advantages like scalability already mentioned. Additionally, customers will benefit from the Infrastructure-as-a-Service platform that supports all types of hardware resources, making it possible to find the exact resource you need. With SONM, consumers can instantly release and grow resources within the computing fog. In addition, security is always maintained regarding the supplier’s reputation. For added security, SONM is working toward hardware-enforced security, as well. Finally, consumers benefit from high market liquidity in purchasing resources and the ability to scale out their application. SONM’s ICO was held on June 15, 2017 and successfully raised $42,000,000. Paolo Tasca, a digital economist and blockchain expert, joined the SONM Advisory Board. Tasca is the Executive Director of the Centre for Blockchain Technologies at University College London, as well as a blockchain consultant to the United Nations and EU Parliament, and the co-editor of “Banking Beyond Banks and Money: A Guide to Banking Services in the Twenty-First Century.”'
