Like normal ordinary applications, dApps are a type of blockchain-based applications that can be applied over a variety of use cases, including freelancing (online services), lending apartments, in escrows meant for real estate deals, car leasing deals, ICO contracts, in the creating of custom ERC20 tokens, in affiliate systems, crypto wallets, in e-commerce platforms, and in online services.

There are other areas that smart contracts can be applied including delivery of containers, long-term contracts with delayed or step-by-step payment, chained contracts, multilateral contracts and small business applications such as automatic payments, ordering services, internal and international trade. The list is endless when it comes to applying blockchain dApps within a business setting.

These four tools can help you experiment with our first dApp, easily.

Dappbuilder

Dappbuilder, which aims to be a WordPress of Blockchain, allows anyone to get different templates to build different types of dApps including voting dApps, escrow dApps, Multisignature wallets, betting dApps, ICO token generation, custom token generation, and many other types of dApps.

How it works?

The app was founded by Ibuildapp, which is a mobile app builder. How it works is after creating of and logging into your account, you can select the type of template you want to use to develop a dApp depending on the type of dApp you want to build.

Lets assuming you have already decided on the type of dApp you need. For instance, I select Escrow dApp template to build an escrow dApp that utilizes Ethereum smart contract protocol. My type of dApp is a simple Escrow dApp that allows a seller and buyer to transact based on the terms of sale stipulated by seller or agreed upon by both the buyer and seller. The smart contact dApp also includes an escrow agent to see the evidence of shipment and initiate transfer of funds. The seller must provide the evidence to agent to get payment. The agent can get a small fee of the transaction for his or her arbitration.

The process of creating a dApp is simple thanks to the available template, yes but these are very very simple over-simplifed examples of what a smart contract can be: its way more too complex than this due to security requirements.

To do a sample of a simple app with dappbuilder.com, just fill in the dApp name, price in Ethereum — which is the price in ETH the seller needs to receive as payment for his products; then fill in the sellers, buyers, and arbitrator’s Ethereum addresses; then the fee in ETH that is to be paid to the arbitrator.

You can also set limit for the payment agreement on the dApp. And Urrah!

To complete the process, you will need to install Metamask, unlock your account, and choose Main Ethereum Network or Rinkeby Test Network as an alternative.

This near last process is simple because Metamask, for instance, is web-based extension for both Mozilla and Chrome and can be downloaded and installed immediately within seconds on the browser. You then proceed to create an wallet account with Ethereum network or login into one (by using your recovery seed) if you already have it.

For your info, Metamask now also works for Android and iOS.

So in short, Metamask just allows to create a wallet and access the Ethereum network and you can also choose testnet if your dapp is to go to testing instead of live network. So if you want to test your dApp use the testnet platforms.

You then can create and publish the dApp.

For people who are looking for other features in a dApp development tool, Dappbuilder allows people to not only use the templates but to also create custom dApps using code. The platform provides a manual to help you ensure that the contract adheres has some required specific logic and special method to work on dApp builder platform.

dApp Builder also features a community reviewed smart contract marketplace where users do publish their dApps and find dApps they can customize. It also provides a web interface for the user’s dApp and users can publish their dApps on Google Play.

Embark

Embark provides options and templates for different use-cases. It allows one to build and deploy decentralized applications and integrates with Ethereum blockchains, decentralized storages like IPFS and Swarm, and decentralized communication platforms like Whisper.

It makes building of dApps creation as easy as possible by providing all the necessary tools for the process. Some of these features include automatic smart contract deployment that allows development as well as deploying of smart contracts, client development which allows building on an app with framework of choice within Embark, testing feature that allows users to test their dApps using Web3 JavaScript.

Embark also allows the distribution of dApps through IPFS, provides peer-to-peer messaging to allow receiving of messages from protocols like Whisper; and also Cockpit, a companion application that makes developing and debugging of decentralized applications a breeze.

In order to start building dapplications using Embark, you need to first install Node, Ethereum Client (optional), IPFS (optional). Ethereum Client allows spinning up an Ethereum node: Embark has Ganache CLI but geth is required in order to run a real node. You install Embark through a package manager of your choices such as the Node Version Manager, which allows installing of different versions of Node in isolated environments without need to change permissions when installing packages.

Once these have been installed, run the demo account using the demo command which will scaffold and set up a complete application for the user to play with.

From the dashboard, you can select Contracts, Environment, Status, Available Services, or Logs and Console smart contract templates or demo contracts. Then open up a terminal of choice and run the demo commands ($ embark demo and $ cd embark_demo) to create a demo application. The run command is then used to run the application. Embark not only compiles and deploys the smart contract that comes with the demo app to a custom blockchain in the user’s local machine, but also compiles the web app that is part of the demo and deployed to a local web server. You can also open the web page if it does not open the browser automatically.

The help! command provides the list of commands that the user can run inside the dashboard.

Flow

Flow allows developers to easily build games, apps, and the digital assets smart contracts. Using it, developers get to develop crypto-and crypto-enabled businesses on which consumers can control their own data and build economies through which their services and businesses are accessible from anywhere in the world. Users can build Ethereum-based applications and also achieve consumer-friendly on-boarding.

To enhance on-boarding, Flow, for instance, allows fiat-to cryptocurrency conversion.

Smart contracts developed using this platform are also upgradeable. They can first be deployed to the mainnet in a beta state and incrementally updated by the original authors. Users can get alerts on unfinished nature of this code and can choose to wait until the code is finalized before trusting it.

The smart contract can be made immutable once ensured and confirmed safe.

For developers, Flow offers templates that allows one to go through the fundamentals of developing on-chain currencies, collectibles, marketplaces, and more. You can go through building of simple applications such as marketplaces, non-fungible tokens and fungible tokens.

Ideally, the PlayGround is a sort of tutorial where you can go through and practice building of dapps. For instance, you can learn to build marketplace dapps or smart contracts that incorporate fungible and non-fungible tokens. For instance, you can learn to build marketplace dapps or smart contracts that incorporate fungible and non-fungible tokens. You get access to basic code or templates for these dApps and directions on how you can interact with the codes.

You can get access to a basic NFT contract structure, learn how to edit it, and learn how to deploy it on the mainnet. For instance, for building a non-fungible token (NFTs), the starter code provided is here.

Teelkee

Teelkee is a dApp builder for Steem platform. It also features a marketplace where users can access DApps plugins and distribution with premium features.

Teelkee allows anyone to tokenize their assets and launch the token via dApp on Steem blockhain. The user does not even need to be a programmer or to have deep knowledge of how blockchain functions. Instead, a user gets connected to people who have the knowledge and allow you to create your tokens. It aims to democratize tokenization on the blockhain in the same way WordPress enables people to create their own websites without coding as would be needed through coding.

It supports building of applications on mobile and desktop. by providing the functionality needed to create and tokenize dApps and plugins and themes. The platform is powered by Smart Media Tokens and users can deploy their dApps on Steem without a need to support their own publicly-tradable ERC-20 token.

Building can be achieved by just drag and dropping modules and selecting a few parameters in the UI interface. This makes it easy to create and edit social DApps with no coding skills. In addition to providing mobile development and hosting platform for Steem developers, there is a marketplace of dApps, plugins and themes. The platform also connects businesses with the blockchain technology even if it is not a trivial task to integrate applications and blockchain for businesses. It is in early testing phase and admission is via application.

Price of XRP Increases By 17% Bringing Stellar To A New Peak

XRP Stellar

Rate this post On a typically lazy Sunday, XRP and Stellar are performing impressively. The price of Stellar and XRP are continuously increasing.

McCaleb was one of the creators of the Ripple protocol, which runs on the XRP cryptocurrency. To focus more on Stellar (XLM), he left Ripple in 2013. Stellar’s payments network is quick, inexpensive, and easy to use, similar to Ripple.  XRP is a cryptocurrency based on Ripple’s market capitalization is $57 billion, while the market capitalization of Stellar is $18 billion. Comparatively, Stellar has performed much better than Ripple in the past few weeks. It has increased by 31.9% in the last seven days, while XRP has only increased by 4%. Elon Musk’s economic tweets, in which he slammed Bitcoin as unfriendly to the world, contributed to both companies’ growth. Musk depressed the price of Bitcoin from the mid-$50,000s to $49,000 in a single tweet this week. Why Does Bitcoin Consume Too Much Energy? Both Stellar and XRP use less energy as compared to Bitcoin; to authenticate users, they depend on a small number of blockchains, whereas Bitcoin relies on a large network of power-hungry computers.

Hedera Hashgraph has increased by 16.37% to $0.36, Solana has increased by 15% to $47, Cardano has increased by 10% to $2.39, and Algorand has increased by 8% to $1.53. The majority of the above are based on proof-of-stake, a consensus algorithm that allows those who own the most coins to validate transactions.

Binance Coin, XRP, Dogecoin Price Analysis: 16 May

Republished by Plato

Published

on

Binance Coin headed south towards $500-$510 support – a region bolstered by the 50-SMA (yellow). XRP jumped by 16% on strong volumes but its technicals were yet to reflect a strengthening bullish trend. Finally, Dogecoin could see further dips before a rise above $0.569-resistance.

On the 1-day chart, Binance Coin slipped below $600 and its 20-SMA (blue) and headed towards $500-$510 support – an area that clashed with the 50-SMA (yellow). With large-cap alts trading largely in the red after bearish cues from the market leaders, BNB was no exception. Warning signals came in the form of a bearish twin peak setup on Awesome Oscillator.

Furthermore, bearish divergence on RSI indicated weakening prior to BNB’s dip. At the time of writing, RSI traded in neutral 50-territory. On the 4-hour chart, BNB moved below its 200-SMA and although traders could go long at the current price level, a further pullback towards $500 could be on the cards depending on broader market cues.

XRP

XRP bashed away multiple bearish signs and jumped by 16% in the last 24 hours. Bullish sentiment may have stemmed from Ripple’s response to the SEC’s request of an informal conference to discuss all legal advice that Ripple has solicited during the past.

A series of successive green candlesticks were spotted on XRP’s daily chart and underscored buying resurgence. According to XRP’s technicals, bulls were yet to fully assert control. MACD was close to a bullish crossover, while RSI headed towards the 60-mark. A break above $1.75-resistance could spur some additional buying, while $1.31-$1.22 would provide support in case of further pullbacks.

Dogecoin [DOGE]

Source: DOGE/USD, TradingView

Even though Dogecoin was slightly bullish, the price remained below a key resistance level at $0.569. In fact, Squeeze Momentun Indicator noted weakening buying pressure and it seemed unlikely that $0.569 would be toppled over the coming days – barring any social media anomalies. Support marks stood at $0.37 and $0.44.

MACD line remained below the Signal line- underlining recent woes for DOGE. On the lower timeframe, a degree of equilibrium was noted between the buyers and sellers. If this continued over the coming hours, some consolidation can be expected before the next upswing.

Facebook’s Diem Unveils Its Latest Stablecoin Plans and Strategic Move to the United States

Republished by Plato

Published

on

Diem, the cryptocurrency project headed by Facebook originally known as Libra, recently announced its plans to launch a stablecoin with its focus scaled back to the United States. 

The company stated earlier this year that it would be relocating its primary operations from Switzerland back to the United States, and would withdraw its payment system license application from Switzerland’s financial regulators. “Diem is simplifying its plans for [its] USD stablecoin issuance by shifting its main operations from Switzerland to the United States,” they said.

This decision was later confirmed by the Swiss Financial Market Supervisory Authority. 

Stablecoins are digital currencies pegged to a fiat currency, with Tether (USDT) and USD Coin (USDC) being two prominent examples. California-based Silvergate Bank will become the sole issuer of the Diem USD, while also managing its dollar reserves. 

Diem to Launch Wholly New Subsidiary Diem Networks US Alongside Crypto Bank Silvergate

In a strategic partnership, the two firms have created a new subsidiary called Diem Networks US — which will run the Diem Payment Network (DPN) to facilitate transactions of Diem stablecoins within its network. 

“Silvergate is a leader in financial innovation and an ideal partner for Diem as we move forward with a blockchain-based payment system that protects consumers and enhances the integrity of the financial system,” said Stuart Levey, chief executive officer of Diem.

“We are committed to a payment system that is safe for consumers and businesses, makes payments faster and cheaper, and takes advantage of blockchain technology to bring the benefits of the financial system to more people around the world. We look forward to working with Silvergate to realize this shared vision.” 

Diem’s strategic shift to the United States comes at a time of a rapidly evolving regulatory environment for cryptocurrencies and blockchain technology. 

Some municipalities and states such as Miami and Wisconsin have embraced the recent innovation, whereas regulators such as the newly-appointed SEC Chair Gary Gensler have critiqued the autonomy of the crypto industry. 

With crypto ETFs and related financial products under intense scrutiny by the SEC, it remains to be seen whether Diem’s decision to relocate back to the United States will bear any fruit.
