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.
Particl is an open-source and decentralized privacy platform built on the blockchain specifically designed to work with any cryptocurrency. It allows decentralized applications (Dapps) of all sorts to be built within a secure, highly-scalable environment and be integrated directly into Particl’s flagship wallet: Particl Desktop Particl's mission is to foster a new decentralized, private and democratic economy supported by its platform and native currency (PART). All the fees generated by the platform are paid to the PART coin holders who are securing the network. PART is a privacy coin built from the Bitcoin Core codebase and is always updated to its latest version (currently 0.16.0). Capitalizing on the latest Bitcoin codebase not only allows the Particl platform to benefit from both Bitcoin’s stability and security, but also enables developers to leverage and easily fork any product, service and technology development from the Bitcoin developer community. Particl Cold Staking is enabled by smart-contract functionality and lets users securely delegate staking powers to “staking nodes” which contain no coin. The purpose of these “staking nodes” is to provide a dedicated resource connected to the Particl blockchain and stake on behalf of another wallet without being able to spend its coins. In other words, it allows users to stake offline coins. Particl's decentralized marketplace is built with privacy at its core and offers a low-cost, secure and scalable e-commerce experience. Designed to work with almost any coin, it uses several privacy-enhancing features such as default private transactions, encrypted data, secure messaging, IP address anonymization, metadata stripping, private listings and more. It is exclusively governed by the Particl community which also earns all the fees generated by the marketplace. Particl is designed so that users can easily use and build decentralized applications that can then be integrated directly into Particl Desktop. These applications foster the decentralized, private and trustless Particl economy and are built using native privacy smart-contracts. PART can be sent as three different privacy states, each with their own degree of privacy and cost: Public, Blind, Anonymous. Each state has a purpose within our privacy platform and also provides the user full control of the linkability and traceability of their transactions. Particl is the first coin in history to deploy these privacy protocols on a Bitcoin Core codebase. The Particl platform accepts a wide range of cryptocurrencies and provides maximum privacy at the same time. By using atomic swaps and third-party integrations, all incoming currency transactions are automatically converted into PART, Particl’s native currency. This way, you can use your favorite cryptocurrency while being protected by PART’s powerful privacy features.
