Solidity for Beginners: A Guide to Getting Started

Solidity is a pristine programming language formulated explicitly for developing smart contracts for the Ethereum blockchain. The newly developed language has gained a significant role under Ethereum’s contracts framework that is of great importance in blockchain technology; in fact, you will be required to learn the language in order to code Ethereum Dapps (Decentralized Applications). The developers created this language with an aim to showcase the real potential of the system of smart contracts in the realm of digital exchanges.

This article will provide you with a detailed understanding of smart contract systems, solidity language, functionality, and solidity basics. These fundamentals will lend you basic knowledge about the subject to help you in getting started.

What Are Smart Contracts?

The term smart contracts have gained a ton of publicity since its formulation; it’s been at the center of attention just like other popular terms like AI (artificial intelligence), Machine Learning, Blockchain, etc. Smart contracts, also known as crypto-contracts, are automatic computer programs that empower currency tradings, digital asset exchanges, and other kinds of businesses. These exchanges are secured by a predefined set of rules summoned as a smart contract system. Thus, smart contracts not just guarantee that both the parties are adhering to the principles and regulations of the smart contract but also automatically implement the contract obligations.

What is Solidity?

Solidity is the principal programming language for assembling smart contracts utilized in the Ethereum blockchain. It is a contract-based language, which implies that smart contracts are liable for putting away the entirety of the programming reasoning on which the Ethereum blockchain runs. It is statically formulated to uphold essential elements like libraries, legacy and that’s just the beginning!

Solidity is an easy language purposely made for an oversimplified way to provide genuine solutions for the issues of real-world use cases. The language has been implemented on the Ethereum platform, a Virtual Machine carrying out the blockchain network to foster decentralized public records to make smart contract frameworks. This programming language has similar functions as JavaScript and C++. Moreover, the language upholds state factors such as value types, data types and programming capacities.

However, the language still deals with constant updates and modifications across the platform. Subsequently, an aspiring SOLIDITY DEVELOPER should be aware of the updates through forums of the Ethereum platform, chat rooms, and websites. Currently, Ethereum and Solidity are both going through visionary growth.

Solidity Basics for beginners

Solidity language supports the following general value types:

Booleans: It returns a true or false value.
Integers: The int/unit for both unsigned and signed integers are supported by Solidity.
Address: An address can carry up to a 20-byte value.
String Literals: String literals are depicted using either double or single quotes. They imply trailing value zeroes.
Modifier: Modifiers ensure the fulfillment of the predefined conditions before code execution.
Mappings: Mappings return values related to a given storage site.

These generic value types can be further integrated to develop complex data types.

How is the compiling and testing of smart contract done?

Once you have created a smart contract using Solidity on a local system, install an easy-to-use test environment that accepts simple Truffle commands. The compiler transforms the source code into the Ethereum Virtual Machine code, allowing you to test your code without needing to pay Ether coins.

An overview: Solidity flow of execution

The syntactical consonance of Solidity with another programming language, JavaScript, has extensively improved the system’s usability. As a beginner, you must have a clear idea of the execution process under a solidity programming language command:

The Ethereum format documentation draws out an instruction text size of 32-byte containing a stack and memory model. The EVM generates a program stack that monitors the registries under information storage and program counter. To keep a successive stream to control the program, the program counter loops/jumps.

Additionally, the virtual memory lends short memory for information distribution that is expandable to some degree compared to a permanent storage allowance provided by the nodes of the blockchain.

The aim of creating solidity language for Ethereum is to maintain the determinism and accuracy of smart contracts. The node executes programming tools and smart contracts within the connected blocks in the Ethereum for creating a new block.

This implies the code being executed is enrolled based on the sequence of the block.

While entering the new stage of the execution process, the program phase gets shifted to new storage exchanges. At first, these exchanges are performed at the miner’s location. After execution, the new block is dissipated to different working nodes within the blockchain.

To confirm the credibility of the framework of smart contracts, every node autonomously checks the block by correlating the state changes by using any local copy of the block. In cases where the state changes are deterministic, nodes of the blockchain accept the exchanges. Similarly, in a circumstance where the nodes could not reach an agreement, the execution of the block stops, and the network may end.

Closing Thoughts

Solidity is the language that has the power to develop the frameworks of contracts with robust functionality. Smart contracts have generated ample opportunities for further blockchain developments and multiple sectors of online business. Hopefully, you learned the fundamentals of solidity programming language to use while creating your smart contract.

Dogecoin Price Hits $0.176 after a 22% Dip – Where to Buy DOGE

Altcoins are having a hard time recovering, with the majority of them deep in the red zone. One of the worst-hit tokens is dogecoin, which has lost 22% in the past 24 hours.

In the past month, DOGE has lost nearly half of its value. However, those who invested at the beginning of the year are still in profit since the token’s current price is almost 7,000% higher than what the coin was trading at the beginning of the year.

At the time of writing, DOGE had sunk below critical $0.20 support levels and traded at $0.176 on major exchanges.

Dogecoin Price Analysis

It seems that DOGE’s glorious days may be coming to an end. The meme coin gained popularity after Elon Musk affiliated himself with it and promoted it on his Twitter account. However, Musk is yet to come to the rescue of DOGE this time round. His silence comes weeks after a threatening video by the Anonymous hacker group was released, criticizing him for misusing his power over the crypto market.

DOGE Price Analysis 22 June 2021 — Source: TradingView

The chart above shows how dogecoin has been performing this month. The highest downtrend for the token started this week, as can be seen above, which could be attributed to the lack of support from the broader crypto market. After BTC sunk to almost $31,000 at the beginning of the week, altcoins followed suit and dogecoin was not spared.

Dogecoin needs to push past $0.20 to prevent a further retreat. Currently, the meme coin is on the verge of losing its coveted position among the top ten cryptocurrencies. Losing its space could be devastating for the token.

Dogecoin holders are urging Elon Musk to step in and save the meme coin from any further turmoil. However, his silence on the matter could indicate that the billionaire is keeping his sentiments about the crypto market to himself ever since he was accused of manipulating the market and misusing his power in the sector. However, not all is lost, and we may see the CEO tweeting about his favourite coin soon.

The current price movement could be because of a market correction, given the coin’s massive gains. However, it is worth noting that DOGE’s price gains merely resulted from investor demand. If the token gains practical adoption for use in the real world, such as in global financial systems, its value will definitely shoot.

Dogecoin has a strong community of fans compared to other cryptocurrencies, which is one of DOGE’s strengths that will help it with its long-term value. Due to its growing fan base, dogecoin has been accepted as a payment method for Wag, a dog-walking app. An increase in use-cases for DOGE will boost demand and hence value.

How to Buy DOGE

To purchase dogecoin, you need to create an account on a crypto exchange. One of the exchanges that support DOGE is eToro. The exchange is highly secure and reliable. Besides, its trading fees are highly competitive, and it offers a wide array of outstanding features for new investors. In addition, the exchange is among the few that offer copy trading, and if you have never traded crypto before, the exchange will provide you with a demo account where you can learn.

Portugal Grants First Crypto Exchanges Operating Licenses

For the first time ever, Banco de Portugal has approved operating licenses to regional cryptocurrency trades.

Recently, the central bank gave out the statement that Portuguese-based trades “Mind the coin” and “Criptologia” are now enlisted as virtual assets service providers.

The central bank has issued only these two names in the list on their official website. Banco De Portugal took around nine months to finalize the decision. In September 2020, Criptojola was reported to perform its initial registration to give out its services as a virtual assets provider.

Mind the Coin and Criptoloja have been given permission to perform crypto exchange services between fiat currencies and different virtual assets within the Portuguese region. Furthermore, they are also allowed to cover various transfer services, safeguarding, and administration works for such assets.

Banco De Portugal has been awarded as one of the most crypto-friendly nations in entire Europe, and the whole continent seems to be proud of it.

In May 2021, Jean Galea, a well-known investor, and blogger said that Portugal is becoming a haven for all the individuals involved in the crypto world in one of his write-ups. Cryptocurrency income continues to be immune from capital gains taxes and VAT in Portugal unless the income is associated with professional trading activity.

Which other European countries are involved in Crypto exchanges?

Nonetheless, Portugal isn’t the only European country to accept crypto trading and services with a warm welcome.

In the final week of May 2021, The Malta Financial Services Authority (MFSA) granted “XCoins,” a country-based leading exchange provider, the license to class 3 VFA (Virtual Financial Asset).

The founder and CEO of XCoins, Rob Frye, stated that Xcoins is dominating the space of digital assets worldwide by standing as one of the earliest cryptocurrency platforms to reach this benchmark implies that they are completely capable of paving the path for an additionally secured and organized industry.

This is another such authorization the Malta Financial Services Authority has consented to a crypto trade this year. The firstest crypto platform to obtain a VFA authorization of a similar degree was “Crypto.com.” By earning the milestone of receiving the license a couple of weeks before XCoins, the company called this achievement a historic moment for the cryptocurrency world.

Moreover, Crypto.com had previously made a plea to the MFSA to serve as a licensed financial institution, but the plea didn’t get approved. Again this year, the company has presented its plea to the Maltese authority; however, the regulator’s verdict is still not finalized.

European countries like MFSA and Portugal are surpassing the crypto exchange milestone!

Conclusion

Further, Criptoloja is currently seeking to bring Portuguese folk together who are interested in investing in crypto assets. However, the service provider company is not confident enough to start accounts in out-of-country trades. Nevertheless, investors say that the tremendous adoption of cryptocurrencies in Portugal is forming a new era of traders.

Crypto-finance company Amber Group valued at $1B following $100M raise

Cryptocurrency investment platform Amber Group has added $100 million to its coffers following a successful Series B fundraiser, bringing its total pre-money valuation to $1 billion — a major milestone for the firm as it enters its fourth year of operations.

The cash injection will be used to “expand global operations to meet client demand and develop market solutions for the world’s leading crypto investors and companies,” co-founder and CEO Michael Wu said.

Measures of trade volume and total assets under management showcase Amber Group’s significant growth over the past four years. The company now has over $1 billion in assets under management, with more than $500 billion worth of cumulative trade volumes.

“We’ve had record months over the past quarter across both client flow and on-exchange market-making volumes,” Wu said, adding:

“Since stepping up our on-screen presence, we now account for 2-3% of total trading volumes in major spot and derivative markets and are continuing to see growth. Our cumulative trading volumes have doubled from $250 billion since the beginning of the year to over $500 billion.”

In terms of notional trade volume, Amber Group ranks 21st among global exchanges, according to BitMEX data.

Amber’s assets topped $530 million in 2020, representing a 275% increase from the prior year. At the time, Wu told Cointelegraph that his company has “already proven we can provide institutional-grade integrated crypto financial services.”

In addition to its Series B backers, Amber Group has received direct funding from some of blockchain’s biggest venture funds, including Pantera Capital, Coinbase Ventures and Blockchain.com.

Venture funds have poured billions of dollars into the crypto economy over the past six months, highlighting their conviction in the new asset class. Just this month, Solana Labs finalized a $314 million private token sale, PayPal and Salesforce contributed $14 million to TRM Labs and DeFi exchange dYdX raised $65 million through a Series C fundraiser.

3 reasons why Ethereum may underperform Bitcoin in the short-term

Ether (ETH) price outperformed Bitcoin (BTC) by 173% from March 28 to May 15. The incredible bull caused the token to reach a $4,380 all-time high. However, as cryptocurrency markets initiated a sharp drop on May 12, the trend started to reverse, and since then, Ether has underperformed by 25%.

Some might say it is a technical adjustment after a strong rally. While this partially explains the move, it excludes some critical factors, including the fast advance of smart-contract network competitors and Bitcoin being adopted as an official currency for the first time.

Notice how the ETH/BTC ratio rallied again on June 8, reaching 0.77 despite Ether’s price remaining 36% below its all-time high and ranging near $2,800. To understand what could have been driving the ratio, analysts need to analyze Ether and Bitcoin price drivers separately.

Mike Novogratz may have been misinterpreted in his interview

Ether’s bull run potentially got an extra leg due to intense praise from institutional investors. Traders could have picked up a sense of urgency, known as FOMO, and promptly shifted their Bitcoin exposure towards the leading altcoin.

On May 13, New Yorker magazine published an interview with Mike Novogratz, the founder, and CEO of Galaxy Digital. In the conversation, Novogratz said:

“All of a sudden, you have decentralized finance and NFTs both on Ethereum at the same time roughly, with wild accelerating growth.”

Novogratz was then questioned on how much higher Ether could reach, to which he answered:

“You know, it’s dangerous to give predictions on the highs. But could it get to $5,000? Of course it could.”

While an Ethereum holder might have interpreted it as a prediction, others could have understood it as a wild guess, likely depending on general crypto market conditions.

However, roughly a week later, a report from Goldman Sachs revealed the global investment bank believed that Ether had a “high chance of overtaking Bitcoin as a dominant store of value.” Interestingly, one of the main quotes in the report was directly from Novogratz’s interview with the New Yorker.

At its peak, Binance Chain controlled 40% of DEX volume

While Ethereum has kept its 80% dominance on net value locked in decentralized finance (DeFi) applications, Binance Smart Chain (BSC) has reached a 40% market share on DEX exchanges.

The successful growth of the DeFi industry and non fungible token (NFT) markets caused intense congestion on the Ethereum network, raising median fees to $37 in mid-May. That bottleneck triggered an activity exodus to competing networks, and PancakeSwap was best positioned to capture that flow.

To make things worse, important DeFi projects expanded to Binance Smart Chain, including yield aggregator Harvest Finance and decentralized exchange aggregator 1inch. Investors quickly realized that the trend could continue as the competing smart-contract network provided an easy solution for dApps looking for cheaper alternatives.

No country is adopting the ‘Ethereum standard’

Bitcoin might have had a subpar performance over the past 30 days because it has failed to break the $42,000 resistance multiple times. However, a major milestone was achieved when El Salvador became the first country to make Bitcoin legal tender on June 12.

After the Central American country made the decision law, a handful of other Central and South American countries began discussing the advantages of taking a similar path.

Ethereum is undertaking a redesign that will change the issuing rate and how entities get paid to secure the network by moving away from the Proof of Work model. Meanwhile, Bitcoin is making sure that every upgrade is backward-compatible and maintaining its strict monetary policy.

That is the main reason why Ether will not outperform Bitcoin over the next 12 months, or at least until there’s a better understanding of how Ethereum network dominance of smart contracts will be.

Professional investors avoid uncertainties at all costs, and cryptocurrency markets already present plenty of that. There’s just no reason for institutional investors to ignore the risks while competing networks eat Ethereum’s lunch.
