8 Computing Solutions at the Forefront of the New Economy

In recent times, the traditional economy and the digital economy has been exposed to new and exciting technologies that promise a more decentralized, secure, and fast network for users. In this article, I have included some of the main players in this developing market.

1. Golem

Golem is an open-source, decentralized computer network.

How Golem Works

The Golem Network is a market for computing power, where users can earn from ‘renting’ their machines or by developing and selling software.

Within the network, users renting computing power are called “providers” and users acquiring power are called “requestors.” The requestors utilize Golem for various purposes, including graphics processing, data analysis, microservices, and machine learning.

Benefits

  • The work division means that tasks can be completed simultaneously, thus enabling shorter timelines for projects.
  • The cost of doing business is less than cloud-based services.
  • Users can be instantly paid for their work with the Golem Network Token (GTM), a token on Ethereum blockchain.
  • Golem is building their whole stack from bottom to top, an approach that typically results in great UXs.

2. iExec

IExec is a decentralized marketplace for cloud services focused on blockchain-based distributed applications and affordable, high-performance computing.

iExecc Dapps

Unlike Golem, iExec (since the release of its v1) allows anyone to develop and run applications.

The iExecc Dapp store contains a variety of apps. Considering the experienced team behind iExec, their reason to choose the Dapp pathway is that there’s probably less competition here. After establishing themselves in the decentralized Dapp market, iExec plans on expanding into decentralized computing tasks.

RLC

RLC is short for ‘Runs on Lots of Computers,’ and it’s the native token of iExec. There are currently 87 million of the ERC-20 token in circulation.

3. Ethereum

Ethereum is an open-source, blockchain-based platform that enables users to build decentralized applications. The computations are performed in an isolated environment called Ethereum Virtual Machine that resides in all node connected on the network. The product of the computations is stored on the blockchain.

Features of the Ethereum Blockchain

Ether

Ether is the currency of the Ethereum blockchain. The cryptocurrencies ETH (Ethereum Hard Fork) and ETC (Ethereum Classic) are two values of Ether.

Smart Contract

The EVM is capable of executing a “smart contact,” an algorithm that stores and automatically executes terms of agreements. Both parties involved in a transaction agree to the terms written in the smart contract.

Bitcoin vs Ethereum Platform

The Bitcoin blockchain focuses on a set of pre-defined operations, such as tracking Bitcoin transactions, while Ethereum allows users to run code of any complexity, making it suitable for any decentralized application, including cryptocurrencies.

Consensus Mechanism

Computation on the Ethereum network cost more and take longer than a standard computer because of the parallelization of computing. To maintain consensus, all participants must agree over the order of all transactions that have taken place, whether they have taken part in the transaction or not.

Ethereum nodes store the most recent state of each smart contract, along with all of the Ether transactions. As EVM is an isolated system, the code runs without access to the network or the filesystem. So, there’s limited accessibility even among smart contracts.

4. Hyperledger Fabric

Hosted by the Linux Foundation, Hyperledger Fabric is an open source distributed ledger technology (DLT) having a modular and configurable architecture that can be employed at the enterprise level in various industries.

Features of Hyperledger Fabric

Privacy, Development, and Performance

  • The Fabric platform enables permissioned, private operation where the operators know each other and can be bound by rules, such as a legal agreement.
  • Fabric supports smart contracts written in common languages, such as Java and Go, so no additional training is required to create the smart contracts.
  • Performance is enhanced because, unlike Ethereum, only parties taking part in the transaction have to reach consensus.

Fabric Nodes

Also unlike Ethereum, Fabric nodes have different roles and tasks in the consensus process. The nodes can be orderers, clients, or peers.

Native Currency

Fabric does not have a native cryptocurrency. However, chaincode can be used to develop a native currency.

5. Tendermint

Tendermint has a blockchain consensus engine, known as Tendermint Core, and a generic application interface, known as Application Blockchain Interface (ABCI). The software enables secure and consistent replication of an application on multiple machines.

Tendermint Core

The Byzantine Fault Tolerant (BFT) middleware of the consensus engine can securely replicate state transition machinery. BFT middleware can tolerate one-third of failures, including hacking attacks.

Tendermint had the goal of offering a more secure and efficient consensus algorithm than Bitcoin’s PoW (Proof of Work). The software formed the basis of important research by consensus protocol Casper’s team: a fault-tolerant chain, such as Tendermint, can make good decisions about who produces a block, while a less reliable chain results in a chicken and egg problem.

The software is user-friendly, replicates applications written in any language, and has multiple applications.

6. Lisk

Lisk is a decentralized and distributed platform that allows users to develop apps and support them with customized blockchains.

Lisk Features

Developers can use Lisk’s JavaScript-based software development kit (SDK) to build both the backend and the frontend of their app. However, Lisk doesn’t offer protection against non-deterministic behavior. Also, the platform can’t prevent infinite loops and measure memory consumption.

Lisk’s Consensus Mechanism

Lisk asks developers to follow “rules” for contracts to ensure consensus. For instance, they ask developers to “don’t use Math.random().”

7. Corda (V 3.0)

Corda is an open source, distributed ledger platform (DLT) catering to the financial industry.

Features of Corda

Corda’s network is a permissioned network – it’s not open to all node operators. The nodes run on Corda and CoDapps and communicate point-to-point with each other.

The ‘doorman’ of each network sets the admission rules for nodes that want to join the network. Like Fabric, Corda offers more privacy because of its fine-grained access control to records, and better permeance because of limiting consensus to the involved parties.

On Corda, contract developers also add legal prose to their contract. This feature consolidates the contract by legitimizing it with the associated legal prose. The platform does not have a native token.

8. Rootstock

Rootstock (RSK) is an open source smart-contract platform that is built on the Bitcoin blockchain.

Rootstock Features

Smart Contracts

RSK is enabling smart contract on the Bitcoin network. It uses the Turing-complete Rootstock Virtual Machine (RVM) for smart contracts. A 2-way peg allows users to directly send Bitcoin onto the Rootstock chain. The RSK coins can be used with smart contracts and Dapps. RSK contracts replicate ‘Proof-of-Existence,’ which is used to prove the existence of a document (or property right).

Security

The RSK blockchain features merge-mining, giving it the same level of security as Bitcoin in terms of settlement finality and double-spending.

SBTC

RSK is a sidechain of Bitcoin. The Bitcoins on the Rootstock blockchain are called SBTC.

RSK is filling the gaps in the Bitcoin network by enabling faster transactions. Besides being convenient for users, it also helps to keep the Bitcoin block size within limits.

Wireless Network Solutions

Wireless networks allow you to stay connected at all times and walk around the work area with your laptop without having to plug in to get connectivity. In an age when new technologies are emerging every day, most of us prefer not to connect our computers through Ethernet cables that make offices look extremely disorganized and cluttered. To do away with too many cables you can simply install wireless networks where a broadcast signal uses a single or more than one router.

The latter are equipped with a port that is connected then to the modem given by your Net provider. When relocating, all you need to do is to physically transfer the wireless network setup. Companies today are extending their networking capabilities to cover areas like Customer Relationship Management and Sales Force Automation. This provides for increased efficiency and ultimately profitability. Emergency services also make use of wireless networking to transfer confidential data because it allows data to be sent and shared faster.

Wireless networks solutions offer many advantages:

1. Connectivity is easy even in regions having poor telecommunication infrastructure.

2. Useful for emergency services that need data transferred fast.

3. Wireless network interface can be conveniently used at home, at the workplace or anywhere for that matter without any trouble.

4. WLANs are easily affordable and available almost anywhere in the world.

5. Relocating only calls for a physical shifting of the interface and installing it at the new place.

6. No need for any cables to connect computers in the network.

7. Savings are guaranteed because cables and other equipments are not needed. A wireless network entails far less maintenance costs as compared to other types of network interfaces.

8. Wireless networking helps to improve productivity in the work area.

9. Wireless routers are pocket friendly and easily available in the market.

However regardless of its many advantages a significant drawback of this development is the health hazards that it brings in its fold. Continuous use of such networks may result in amnesia, lack of concentration, nausea and even life threatening illnesses like cancer. The environment too has been known to suffer because of the electromagnetic radiation that comes out of such networks.

Before to setting up your company’s network, a plan needs to be chalked out to consider all departments and their respective employees. Formulating a strategy and executing the plan in a phased way helps to ensure high success rates and allows you to manage the company budget for the plan more efficiently. A mobility road map or a survey is a precondition to setting up the net. This plan then helps to involve both internal and field workers and the entire work environment and guards against pitfalls along the way.

Samsung Goes Light With Notebook 9

Samsung has released its 9 series of notebooks and tablets. One of note is the new 15 inch Notebook 9.

The 9 is an extreme “light weight” in its class, coming in at just 2.7 pounds. One of the lightest to date of any 15 inch tablet.

Android fans will find much to like about the device.

The chassis is sleek and thin. The design is simplistic in a silver case. The body is magnesium-alloy, which some may find a bit too bendable for a premium notebook.

Samsung has designed a built-in recliner to set the device down to 180 degrees to share your view.

It does have a slim 0.61 inch edge. Coupled with the lighter frame it makes a nice companion for a business trip or vacation.

Speaking of business, the 9 may be lacking in bulk but still has the work ethic.

The left side includes a USB 2.0 port, a USB Type-C port, a headphone jack, and a power input. Flip to the right and find two USB 3.0 ports, a microSD card reader and an HDMI port. There is plenty of connectivity to help complete most any task.

The display is extremely vibrant. Colors pop on the screen with 1080p resolution. Users will find a high-end clarity whether watching movies or editing work documents.

Keys have been ergonomically designed. The touch pad is glass-coated for a smoother ride.

The finger print reader is a breeze to use. It is placed conveniently on the right side of the keyboard. You should be able to log in to Windows in a few seconds.

Power is a plenty. Samsung has packed an Intel Core “Kaby Lake” i7-7500U CPU with 8 GB of RAM, along with a 256 Solid State Drive to handle a heavy workload.

Solid graphics muscle comes from the Intel HD Graphics 520.

The device includes the Windows 10 operating system.

The 9 should also get you through the work day unplugged. Samsung claims you can go up to 12 hours without charging. Re-charging takes about 90 minutes.

Samsung users should be able to generate a lot of performance from the Notebook 9, especially if they already have several Samsung devices.

The machine comes loaded with a handful of Samsung apps, many to sync with a Samsung phone.

SideSync lets you beam your smartphone’s screen to your PC, while PC Gallery and PC Message are useful for quickly accessing your Galaxy phone’s photos and texts. A built-in online support tool provides fast customer service.

On the downside the keyboard can seem to be a bit shallow. The lighter design may also cause some to feel the machine sort of sink as they type a document or answer a bevy of emails.

Pricing for the Notebook 9 starts at $1199.99, which gets you the aforementioned Intel Core i7-7500U CPU, 8GB of RAM, a 256GB SSD and Intel HD 620 graphics.

The extended model adds 16 GB of RAM and a graphics card upgrade for a few hundred dollars more.

While some may be set off by a chassis that seems a little too flimsy and flexible, others will appreciate the high level of performance the Samsung Notebook 9 will deliver. All in a thinner and lighter package.
