Blocknet (sometimes referred to as Block) is a decentralized, platform-as-a-service protocol that connects the nodes of different blockchains. As you probably know, there are hundreds, if not thousands, of blockchains that currently exist, and this number is showing no signs of slowing down its growth anytime soon. Many of these chains, though, are unable to communicate and interact with each other, creating small groups of siloed ecosystems. And, the inability of these groups to work together is holding back the entire blockchain industry. To solve this problem, Blocknet is working to make blockchains interoperable, mobile, and modular. This enables different chains to provide microservices to each other in a peer-to-peer fashion at higher security, faster speeds, and more efficient scalability than today’s current options. Blocknet is aiming to be the “Internet of Blockchains” through inter-blockchain connective services. Simply put, Blocknet enables you to develop on one blockchain, Ethereum for example, but access the functionality of other chains, like NEO. The team is building the infrastructure using three core components that work together to provide three primary services for these inter-chain decentralized applications (dapps). The XBridge, a blockchain router, is the backbone of the Blocknet platform. It’s the first peer-to-peer protocol to connect nodes on different blockchains, allowing them to communicate with one another. Using the XBridge, you’ll not only be able to perform cross-chain atomic swaps, but you’ll also be able to transfer additional data and execute smart contracts across chains. Blocknet uses a Proof-of-Stake consensus algorithm with three types of nodes to maintain the network. Service nodes collect and distribute trade fees on the platform as well as prevent spamming and DDoS attacks. To run a service node, you need to hold at least 5,000 BLOCK and keep your node computer running at all times. The Blocknet team recommends that, if you plan to run a service node, you should also run multiple full node wallets of whichever coins you want to support. This maximizes the trading fees you receive. Staking nodes confirm network transactions. When running a staking node, you’ll receive 9-14% annual returns from block rewards as well as a portion of the trading fees. There’s no minimum BLOCK amount you need to keep in your wallet to receive these, but you need to keep the wallet running at all times. There’s limited information available on the Blocknet team. Dan Metcalf and Arlyn Culwick founded Blocknet in 2014 as a fork of PIVX. According to his LinkedIn page, Metcalf was a Bitcoin developer for 5 years as well as a Senior DevOps Engineer at Philips. Outside of Blocknet, Culwick is also the PR and Media Liaison for XCurrency. Blocknet launched the service nodes on their main net in September 2017, and on March 1st, 2018, the team will release the beta version of the DEX. The project has also partnered with the 0x protocol to add ERC20 token support on the platform. Blocknet is connecting the isolated blockchain systems that currently exist to create one, cohesive ecosystem. Through the platform’s XBridge, the team is building a blockchain Internet in which you can build dapps that utilize features from several different chains. Starting with a DEX, the project has a lot on its roadmap including a service delivery system for blockchains to provide and receive payment for providing functionality to other chains. This is a complex project, but Blocknet already has the partnerships in place (0x, Poloniex) to see it through to the end. Blocknet consists of the following coins: XCurrency, Stealth, SonicScrewdriver, Fibre, Librexcoin, APEXcoin, BitSwift, XCash, UtilityCoin
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.
