Learn to develop dApps with the 4 tools

Like normal ordinary applications, dApps are a type of blockchain-based applications that can be applied over a variety of use

Republished by Plato



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, 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, 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 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 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 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.



NextGen Blockchain Platforms Self-Organize to Win Government Contracts

Republished by Plato



Over the past year, blockchain development communities have turned their attention towards winning government contracts.

Washington, DC. There is a huge opportunity presented by increased government spending on blockchain projects. According to Bloomberg Government BGOV200 Report, federal government spending reached $597 Billion in 2019. However, since new businesses face barriers gaining direct access to government contracts, many have joined the Government Blockchain Association (GBA) to introduce their cutting-edge blockchain platforms to the public sector.

Traditionally government program managers choose to work with the same few legacy companies. For example, there are currently over 4.1 million US Federal government contractors but of the $597 billion in prime contracts awarded in FY19, the top 10 government contractors received $173.4 billion according to Bloomberg Government. However, the COVID-19 Global Pandemic was a catalyst that necessitated governments from around the world look at bold and innovative new ways to solve problems from a more diverse community.

 In March of 2020 the US Department of Health and Human Services hosted a virtual Pandemic Response Hackathon. This hackathon idea completely changed the former process of government acquisitions. The slow pattern of the past was rewritten to adopt to the chaos, uncertainty, and urgency of COVID. Government contracts went from a centralized channel to open and decentralized solutions coming in from completely new sources. A new way of doing business was introduced to the world stage, and in November 2020 the Indian Ministry of Electronics and Information Technology (MeitY), National Informatics Centre (NIC) held their own up a GovTech Hackathon. Throughout 2020, countless examples of crowdsourcing solutions contested the traditional procurement processes.

Along with new paradigms in acquisitions, 2020 brought explosive growth of decentralized development communities and platforms. Decentralized communities operate on independently run servers, rather than on a centralized server owned by a business. Initially, most blockchain solutions were private-permissioned blockchains dominated by a single vendor. One of the most popular government blockchain solutions is Hyperledger Fabric. Though it is technically an open-source project, almost 80% of software changes to Hyperledger Fabric came from IBM, demonstrating an ongoing dependence on IBM to maintain the code.

Lately, next gen blockchain solution providers have been self-organizing into working groups and communities to compete in the contracts space. The largest and most engaged of these decentralized communities is the Government Blockchain Association, with members in over 500 Government Offices, thousands of public and private sector members in 120 Chapters, and more than 50 Working Groups, and 25 Communities of Interests. They also host regular online and in-person events to introduce blockchain solution providers to government officials, promoting this new diverse community.

Some of these next gen blockchain leaders include:

  • DragonChain – DragonChain is an enterprise and start-up-ready platform to build flexible and scalable blockchain applications. It has business-ready applications and developer-friendly integrations that support many applications including learning management systems, decentralized identity, and anti-fraud and compliance solutions.
  • NEM – A community that has developed two blockchains. They are NEM NIS1 and Symbol. NEM NIS1 is the original blockchain offering from NEM, created by the community, and optimized to be a developer’s sandbox. With zero downtime or major outages since 2015, NIS1 is the blockchain you can trust for all your project needs. Symbol is the next-generation enterprise-grade blockchain solution from NEM, purpose-built to help businesses cut costs, reduce complexities, and streamline innovation. With major upgrades in flexibility, security, speed and ease of use, the Symbol platform is the best-in-class blockchain enterprise solution.
  • Simba Chain – SIMBA Chain is a cloud-based, blockchain-as-a-service (BaaS) platform, enabling users across a variety of skill sets to implement decentralized applications (dapps). These apps allow secure, direct connections between users and providers, eliminating third parties. The easy-to-use platform is tailored for users, developers, government, and enterprises to quickly deploy blockchain dapps for iOS, Android, and the web.
  • TON Labs – TON Labs is the core developer of Free TON, comprised of a decentralized team focused on developing the infrastructure and free software for TON OS. TON OS is a full-fledged, vertically integrated technology stack that helps developers work easily with the blockchain and makes it simple and intuitive for users.

Decentralized blockchain projects include the Government Business Blockchain Platform (GBBP). This multi-blockchain platform allows solutions built on any blockchain to connect and become available to governments around the world. Sub-set eco-systems include Emergency Management, Healthcare Delivery, and Citizen Services. Blockchain applications can interconnect on the GBBP, providing identity management, logistics, asset management, payments, and many other blockchain services.

These examples demonstrate how blockchain providers are working together, self-organizing into decentralized entities to build public-facing blockchain solutions. GBA groups regularly host online meetings to discuss their projects. Anyone interested in joining the discussion can find out more on the GBA Events Calendar or Events List. Later this year the GBA will be bringing World-Class Leaders to Washington, DC for Government Blockchain Week on Sept 27 to Oct 1, 2021.

For more information attend a free online event called NextGen Blockchain Platforms on March 17, 2021 or send an email to

Robinhood Reports 6 Million New Crypto Traders in 2021

Republished by Plato



In a blog post on Feb. 26 titled “Crypto goes mainstream” the retail trading app revealed that it had seen six million new customers on Robinhood Crypto so far this year.

The number of new monthly customers buying from its crypto platform in 2021 is 15 times the 2020 average.

“By comparison, this number peaked at 401,000 in a single month last year, with a monthly average of about 200,000 customers trading on Robinhood Crypto for the first time during 2020.”

Robinhood, which had to halt trading in late January due to overwhelming demand, offers just seven tradeable crypto assets; Bitcoin, Bitcoin Cash, Bitcoin SV, Dogecoin, Ethereum, Ethereum Classic, and Litecoin.

There are no trading size limits though it added that the average transaction size is around $500. The chart provided indicates that the average trade was around half of that at $200 to $250 for the previous year.

Retail Traders Surging

The app offers an intuitive user interface and educational articles that explain cryptocurrencies. It is targeted at newbies that may not have the technical knowledge to operate more advanced trading platforms.

It also offers zero-fee trading, but makes money on spreads between makers and takers.

The report reinforces the premise that retail has arrived after months of steady institutional investment which has pushed many high cap crypto assets including Bitcoin and Ethereum to their highest ever prices.

“The numbers are clear: 2021 has started with a crypto bang.”

In a Feb. 18 note from company CEO and co-founder, Vlad Tenev, it was revealed that the total value of customer assets on Robinhood (for all markets) exceeds the net amount of money they have deposited by over $35 billion. He added;

“While markets fluctuate, this tells me that our business model is working for everyday Americans.”

Crypto Correction Deepens

The Robinhood numbers are bullish for overall sentiment, but the crypto correction is deepening and March is usually a bearish month for markets.

Since its all-time high of $1.78 trillion on Feb. 22, total market capitalization has declined by 18% to $1.46 trillion today according to Coingecko.

Bitcoin has been leading the drop as usual with an 18.7% fall from its $58k peak last weekend to just over $47k at the time of press. Meanwhile, Ethereum has been hit even harder, retreating 27% from its ATH of over $2k to below $1,500.

Another 30% correction could be on the cards, echoing the one that occurred in early January when Bitcoin prices dropped below $30k before recovering to a new high. The bigger picture still paints a bull market.
