Vertcoin is a decentralized currency owned by its users, a P2P cryptocurrency in the same vein as Bitcoin and Litecoin. Like its two predecessors, Vertcoin exists solely as a currency, and it uses proof of work to reach distributed consensus. Unlike its two predecessors, however, Vertcoin is dedicated to keeping its mining functions decentralized, so contrary to most PoW coins, it’s ASIC resistant. Branding their project as “The people’s coin,” Vertcoin’s team believes that ASIC resistance invites a fairer, more democratized currency for both users and miners. Along these lines, Vertcoin sports its very own 1-click miner, a program meant to make mining more accessible to the general public. The motivation of Vertcoin was the fact that Scrypt-based ASIC mining chip that is used to mine Scrypt derivative coins such as Litecoin and Dogecoin is entering the mass market. That coupled with strong mining pool causes the strength of a cryptocoin to drop as it becomes easier for a specific party to pull a 51% attack and even monopolize the network. Scrypt-Adaptive-Nfactor was created to address that issue. Vertcoin is zero premined and as of the current design, only 84 million coins would ever be created. Vertcoin is said to be the next generation of coins due to its unique hashing algorithm. There may be more altcoins created based on this hashing algorithm in order to defend their network against ASIC miners. Like most all pre-2015 coins, Vertcoin took a deathblow after Mt. Gox was hacked, throwing the entire market into a crypto winter. As such, it was relatively inactive until the revival last spring/summer. Since then, it has had steady climb up the market cap ladder. A 2014 International Business Times article mentions Vertcoin as a potential Bitcoin successor. The article notes that it ''hopes to offer an alternative. By taking the foundations of Bitcoin and making some adjustments, Vertcoin punishes miners who use powerful machines and work together in 'pools' to monopolise the mining market.'' On July 1, 2014, Vertcoin released a wallet supporting Stealth Address transactions. On December 13, 2014 (block 208301), Vertcoin forked from Scrypt-Adaptive-N proof-of-work function to Lyra2RE as a proactive defense against emerging Scrypt-Adaptive-N capable ASICs. On August 10, 2015 (block 347000), Vertcoin forked from Lyra2RE to Lyra2REv2 because a botnet was controlling more than 50% of the hashing power of Vertcoin network. On May 7, 2017, Segregated Witness (SegWit) feature was activated in the main network. SegWit update includes the Lightning Network technology that was also demonstrated in action during the same day.'
Golem is a decentralized supercomputer that is accessible by anyone. The system is made up of the combined power of user’s machines from personal PCs to entire datacenters. Golem is able to compute almost any tasks from CGI rendering through machine learning to scientific learning. It utilizes an ethereum-based transaction system to clear payments between providers, requestors and software developers however it is safe because all computations take place in sandbox environments and are fully isolated from the hosts’ systems. The company released Brass in 2016 which includes Blender and LuxRender which are the two tools for CGI rendering. There are three releases that follows which are Clay, Stone and Iron. Golem has recently updated their Brass Beta and the highlight of this upgrade are the streamlined task creation GUI, the support for partial task restart in case of subtask timeouts and the fix that should alleviate the issues with the Docker service on Windows. Other than that, improvements have been made on the Blender verification and transaction tracking subsystems and fixed some minor pain-points in the UX. Transaction history will become more user-friendly with separate tabs for payments and incomes. Apart from that, improvements are made for requestors as well, requestors is now able to add resource file without having to repeat the task creation procedure if they have forgotten to add them beforehand. Grand vision and core features ● Golem is the first truly decentralized supercomputer, creating a global market for computing power. Combined with flexible tools to aid developers in securely distributing and monetizing their software, Golem altogether changes the way compute tasks are organized and executed. By powering decentralized microservices and asynchronous task execution, Golem is set to become a key building block for future Internet service providers and software development. And, by substantially lowering the price of computations, complex applications such as CGI rendering, scientific calculation, and machine learning become more accessible to everyone. ● Golem connects computers in a peer-to-peer network, enabling both application owners and individual users ('requestors') to rent resources of other users’ ('providers') machines. These resources can be used to complete tasks requiring any amount of computation time and capacity. Today, such resources are supplied by centralized cloud providers which, are constrained by closed networks, proprietary payment systems, and hard-coded provisioning operations. Also core to Golem’s built-in feature set is a dedicated Ethereum-based transaction system, which enables direct payments between requestors, providers, and software developers. ● The function of Golem as the backbone of a decentralized market for computing power can be considered both Infrastructure-as-a-Service (IaaS), as well as Platform-as-a-Service (PaaS). However, Golem reveals its true potential by adding dedicated software integrations to the equation. Any interested party is free to create and deploy software to the Golem network by publishing it to the Application Registry. Together with the Transaction Framework, developers can also extend and customize the payment mechanism resulting in unique mechanisms for monetizing software.
