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.”'
EtherZero, abbreviated ETZ, is a hard fork on ethereum providing no-fee, high expansibility, real-time transaction or operation feedback services. Aiming to be a general-purpose smart contract platform, ETZ helps developers set up DAPPs that not limited in finance and business scope, but those more frequently used in daily life, to popularize decentralized services to more people and industries. ETZ eliminates the gas fee system from Ethereum network core and adds a Transaction Restriction Policy Protocol layer that associates the threshold, frequency, depth, etc. of initiating transactions with the account balance to combat DDOS like attacks. In particular, ETZ also draws on DASH's two-tier network architecture built with Masternodes transaction verification network and blockchain ledger layer, and its built-in community autonomous system to provide users with real-time operation feedback and high transaction concurrency, no longer need to wait for a long transaction confirmation time. ETZ picks the proven experience of Ethereum on smart contracts, removes its less scalability gas-based fee system and designs a fully accountable trading limit and security strategy against DDOS Class attacks. The final two-tier network composed of the main node and pow consensus layer laid the foundation to achieve free of charge, high concurrency, real-time transactions, independent evolution and several other features. What does no-fee mean to DApp Dev? Taking a simple Todolist DApp as an example, its decentralized implementation can be applied to the team task decomposition process, which requires all participants in the project to know the tasks of other members. Each task is a team consensus result with demand of traceability. The application involves registration of members, additions, deletions and alterations of tasks. According to Ethereum development requirements, all of these operations require gas consumption, which is clearly unreasonable for the users of the application. While in EtherZero, the transaction initiation frequency and the execution depth of smart contracts will be positively related to the balance possessed by the account. This mechanism is similar to POS, it takes into account the fair use of bandwidth and set a relatively high capital threshold required to launch a DDOS attack by malicious attackers while providing free services. This kind of limited and cost-effective free mechanism will spread the decentralized application into the scene of life.
