Solidity Tutorial — Solidity Programming For Beginners

by

Codezeros

Modern tech is dominated by software- from our work applications to social media, everything runs on some complex lines of codes. Blockchains also use programming languages for creating smart contracts and decentralized apps. The most famous of them- Ethereum, has gone a step beyond and created its own programming language called Solidity. As Ethereum is one of the most used smart contract platforms, a huge amount of Blockchain Programming happens over Solidity.

In this article, we provide a beginners’ guide to solidity programming for the Ethereum Virtual Machine. We would be covering the fundamental building blocks of Solidity, its layout, where it stores the data, the common value types, operators, and data structures.

At its core, Solidity is a contract oriented language and resembles the syntax of JavaScript. It is used to execute code on Ethereum Virtual Machine (EVM) for blockchain development. The main feature of the solidity compiler is that it converts high-level codes into machine-level codes, which are simpler to understand.

Contracts are the starting point of any project and contain all variables and functions. Hence, it is the most fundamental building block. Contracts closely resemble classes used in object-oriented languages.

The layout contains pragma directives, import directives, and contract definitions. All this information is stored in a source file.

It is used to define and restrict the compiler version which can run the code. Version pragma works like a security feature to make sure that the code is executed exactly in the way it is intended. A change in semantics would also need a change in syntax and past or future versions could misrepresent the current use of the code.

Blockchain Solidity doesn’t hold the concept of a ‘default exporter’ but supports import statements, from ES6 onwards, that are similar to those in JavaScript. All global symbols from “filename” can be imported into the current global scope, however, it is advisable to import specific symbols individually.

Solidity supports both single-line and multi-line comments. It also contains another type of comment known as natspec comment. A natspec comment is used directly above a statement or a function declaration.

Before we move ahead, it is imperative to understand how and where Ethereum keeps its data.

Ethereum can store its data in the following three crucial areas:

Each account stores certain data in the storage area. The storage area stays persistent between function calls and transactions. The most important feature of the storage area is that the contract cannot read or write any part except its own. However, storage is comparatively costly to initialize and modify, let alone read.

Memory is used to hold temporary values. It gets erased between function calls and there is no requirement to expand it periodically. Hence, it is cheaper to use than storage but its cost would increase the larger it grows.

All computations are performed in the stack area. It holds small local variables and costs close to nothing. However, the stack area can only hold a limited amount of values during a time and, if required, the values have to be shifted to the memory or storage area.

Boolean

There are only two possible values in a boolean: true or false. A number of logical and equality operators can be used to create a boolean.

Integers

In Solidity, signed and unsigned integers of various sizes are possible. Comparison, bit, shift, and arithmetic operators can be used to retrieve information.

The rules applicable in Solidity are more or less similar to other programming languages.

Arithmetic

Solidity uses simple math operators such as addition (+), subtraction (-), multiplication (*), division (/), and modulus or remainder (%).

Bitwise

Used on two complementary representation of a number. For example, ~int256(0) == int256(-1)

Logical

The most common logical operators are: logical and, logical or, logical negation, equality, or inequality.

Incremental

Incremental and decremental operators in Solidity uses a prefix or suffix of either — or ++. For example, a++ and a+=1.

Structs

Structs are used to group multiple variables and works as a way to define new types in the form. It allows one to create complex data types holding multiple properties. A struct can only have 16 members, beyond that it presents an error.

Arrays

Arrays help in creating a collection of structs. These arrays can be a dynamic or compile-time fixed size.

Mappings

Mapping helps in locating each key to the whole byte-representation. Mappings are hash tables which are virtually initialized.

Ethereum Solidity Development has become a leading field in blockchain development. This guide can help early coders get broad insights into solidity programming and experienced coders understanding the similarities between Solidity and their current language. With the expected launch of Ethereum 2.0 in the coming weeks, Solidity is expected to gain more traction in the market.

How much does it cost to develop a blockchain App in 2020?

by

Codezeros

Many businesses have invested in blockchain technology as it has grown enormously over the years. The demand increases many folds when bitcoin and other cryptocurrencies are dependent on it. Using this technology, anyone can carry out secure transactions with almost zero transaction fees.

Sensing the impact of cryptocurrency on the global market, many businesses have started accepting payments in Bitcoin. With blockchain development, you can also safely receive or send cryptocurrencies with other wallets. You can find a large number of reliable bitcoin wallet apps like BitPay, Airbitz, Copay, Paper wallet, etc. So, if you want a customized blockchain app for your Initial Coin Offering (ICO) or exchanges, it is necessary to know if it is worth the investment for your business. You should also know if you could afford it or not. So, this article will help you figure out how much blockchain app development will cost you.

Let’s first get started by understanding what all resources you will need:

Developers

The team who is developing the app is the major factor affecting your project as well as the budget. So, make sure that you hire blockchain developers who are skilled in developing the codes. Mostly, these developers charge average or median hourly rates. If you want to invest less, you can also outsource the task as the prices depend on many factors like country, the popularity of the company, skills, and experience of the developers, etc. However, in any case, it is advisable to consult a blockchain development company to get a better idea as to where this technology fits into your business.

Cryptocurrency

The token is a crucial part of the successful blockchain technology. It is possessed by most of the blockchain projects. So, if you are willing to integrate this technology into your business, you need to stand out among the thousands of cryptocurrency by customizing your powerful cryptocurrency.

Firstly, you will need software developers, technology experts, marketing managers, and PR executives to launch your coin in the market. Other crucial things are investors to gain project credibility, consultants to guide your technology, communication channels to engage with customers.

You might also need to promote new cryptocurrency to gain profit. Your blockchain wallet app will be successful by conveying its importance, attracting the customer, showcasing your technology, etc. After strategizing a marketing tactic, you can start creating your blockchain network.

However, if you want to build hybrid blockchain technology, it takes around a month to develop the network with the help of C++, Python, Java, Solidity, etc. The type of technology affects the least at the cost. With different technical factors affecting, you need to have a budget of around $150,000-$200,000 to create a new cryptocurrency.

Crypto Wallet

With cryptocurrency wallet software, you can securely store, send, and receive digital currencies. Did you know that to access most of the cryptocurrencies, you need to use a cryptocurrency wallet? Every application is developed for Android, Web, and iOS platforms as these are the most popular platforms used by users. You can save some of the development prices by using cross-platform technologies like JavaScript and its frameworks.

Moreover, you can work in REST API with client requirements for the web and mobile devices or else build an application that stands alone. You can consult a top blockchain app development company to understand what is best for your business as each approach has its pros and cons.

For everything you plan, you will need a dedicated developers team, a project manager, a business analyst, and a QA engineer. With the help of cryptocurrencies like Bitcoin, Ethereum and Litecoin, you can build a Minimum Viable Product (MVP) for a cryptocurrency wallet for around $40,000.

The value changes with the type of coins you add to your wallet application. As you know, the wallet app needs to be fully secure and hack-proof as it is financial software. So, it is crucial to implement advanced security features. Moreover, the security of the wallet, as well as the type of coins supporting it, also plays a part in differentiating the prices.

Conclusion:

However, it is difficult to know the price of these wallet applications but we can get average estimates of the market. The cost of the blockchain development project can be from $5,000 to $200,000, depending upon the supporting platform and application scope. So, you need to consider multiple factors before choosing the right budget for your project. You could define the scope of your wallet, supporting platform, and security needs from the start of the project to get a close estimate of your blockchain application development.

Cryptocurrency and a stock market boom pushes TradingView to $37 million in new funding

by

Fueled by last year’s greed-inducing visions of a cryptocurrency boom and a stock market largely untethered from classical economics, TradingView, a developer of social networking and data analysis tools for financial markets, has raised millions in new venture funding.

The New York-based company just scored $37 million in funding led by the growth-stage investment firm Insight Venture Partners .

TradingView has developed a proprietary, JavaScript-based programming language called PineScript, which lets anyone develop their own customized financial analysis tools. The company “freemium” software as a service model that lets most users connect and exchange trading tips and tricks for free, but begins charging when customers want access to more charts, data and real-time server-side alerts.

There are three payment plans beginning at $15, with a mid-tier at $30 and a high-end $60 per-month premium option.

The company had previously boosted its growth by offering its charting software for free to partner websites like SeekingAlpha, Bitfinex and the Nasdaq. That strategy helped it grow to 8 million monthly active users with around 61 percent coming from direct traffic as of March of this year.

These days the company derives nearly 75 percent of its revenue from those monthly subscription plans to individual traders. TradingView’s executives think the company still has an opportunity to expand its footprint among those retail investors, but it’s also planning to make a push to serve more institutional clients with its toolkit.

For the past seven years the company has enjoyed consistent growth, according to TradingView co-founder and chief operations officer, Stan Bokov.

For Paul Szurek, a vice-president at Insight Venture Partners, the investment in TradingView is building off of broad consumer interest in amateur speculative trading. Looking at RobinHood, Bux and eToro as gateways for new investors who eventually move on to more sophisticated tools, Szurek said that TradingView was often their next step into market investing.

“The rise of cryptocurrencies… and trading those assets… has flywheeled into a broader interest in investing across asset classes,” Szurek said.

While TradingView was never crypto-focused, according to Bokov, the company was supportive from the beginning and it’s been a boon to the broader business. “They came for crypto. They stayed for the other stuff,” Bokov said.

And crypto might just be the gateway drug for younger speculative traders to start investing in financial markets more broadly, according to Szurek. “October to January, during the real core of the crypto boom here, there were a lot of users coming in starting out researching that asset class broadly. Eighty percent move on to research other asset classes,” he said. “As TradingView kind of pushed through the [first quarter], trends in growth really diverged from what we were seeing in purely crypto-focused business and that’s a testament to users leveraging this one-stop-shop component of the platform.”

Additional investors in the new TradingView include DRW Venture Capital and Jump Capital. The company was a graduate of the 2013 Techstars Chicago batch and was seeded by Irish Angels, Techstars, iTech Capital and undisclosed angel investors.

“TradingView was built for non-professional traders, but its accessible trading tools and powerful-yet-intuitive charting capabilities have attracted the attention of institutional investors,” said Kimberly Trautmann, head of DRW Venture Capital, in a statement. “As an investor, we are excited about the diverse cross section of the industry that TradingView has reached and its rapid growth. As a proprietary trading firm on an institutional level, we’re looking forward to leveraging the platform and contributing to its further development.”

Surreptitious cryptocurrency miners hide on Politifact and hundreds of other sites

by

Politifact is the latest and perhaps most high-profile website to have hosted code that secretly hijacks visitors’ CPUs to mine cryptocurrency. Driven by a boom in cryptocoin value and a lack of protections against JavaScript routines like this one, this surprising form of audience monetization is now found on hundreds of sites.

(Update: Politifact has removed the code and is looking into how it got there.)

It’s not quite an ad, and it’s not quite malware, nor is it strictly speaking a virus or exploit. JavaScript is used for all kinds of things in the background of practically every major website, from tracking users to displaying custom fonts. Generally speaking, these apps are running code hosted on another server that the end user can’t inspect, and often doesn’t even realize their browser is executing.

In recent months, several JavaScript-based cryptocurrency miners have appeared. The idea, supposedly, is that instead of showing your visitors ads, you have their CPU run the calculations necessary to mine a currency like Bitcoin. As the administrator, you could control the CPU load and reap any resulting coins. CoinHive is a new business that offers this as a service.

Predictably, this already questionable approach to monetization has already been repurposed by malicious actors. Injecting a bit of JavaScript into the front page of a website is often simpler to do than penetrate its databases or phish its admins; and once it’s in, it runs itself — all you have to do is give it a wallet to put the coins in.

That seems to be what happened at Politifact; my blocker registers a CoinHive instance on the main pages of the site, with new requests coming in multiple times a second. Inspecting the site’s JavaScript shows an enormous chunk of CoinHive miner code sitting amongst the ordinary scripts. It’s pretty hard to miss, and if not blocked it takes over the whole CPU until the tab is closed. With a few million users mining for a minute or two each while they check out the latest political shenanigans, those cycles add up quick.

I’ve contacted the site’s team to ask what the story is; someone there told The Register that they’re looking into it, but I’ll update if I hear back with more details.

The site is far from alone: a study by ad blocker company AdGuard showed that hundreds of sites, most of them on the shady site (porn and torrent sites, for instance) are running CoinHive code, or some other JavaScript-based miner.

What can you do? Well, this is a great reason to install an ad blocker, if you haven’t already: in addition to getting rid of intrusive ads and trackers, some of them block unknown scripts or have a blacklist of known malicious ones. I use uBlock Origin, which also makes it easy to whitelist sites (like this one) that only feature organic, free-range advertisements. But you could also use NoScript, AdBlock or any one of the many out there, depending on your platform and browser.
