Overview features of blockchain and its decentralization and secure technology that is tamper-proof, and the ability to track transactions within a peer-to peer network and have proven that blockchain technology could revolutionize the world’s trading and exchange system. While the introduction of modern technology, sophisticated computer programsand fast internet connectivity could enhance traditional trading system to a great extent however, investors continue to face certain challenges until blockchain introduced an actual technological leap. Blockchain introduced the idea of decentralization of trading where traditional exchanges are centralized platforms because they are controlled by central institutions.

A central trading platform takes some time to finish the exchange process and also to confirm the transactions. In the current world of busyness, these days, a time-consuming method sounds unattractive.

To alleviate these problems trading markets are now using blockchain integration in their platforms of choice to increase their competitive edge and increase efficiency as well as transparency and accuracy across exchanges. Blockchain’s fundamental concept seeks to shift control and decision-making power from a centralised system to distributed networks. This is the most efficient way to protect against manipulation of data and fraud.

What is a Centralized Exchange?

Centralized exchanges are online platforms that allow the buying and selling in digital currencies like Bitcoin (BTC), Litecoin (LTC), Ether (ETH) as well as tangible assets like silver and gold. The name implies that the centralized exchanges are governed and controlled by a central authority which is the main distinction between cex and dex. In the end, CEXs act as middlemen between sellers and buyers involved in trading, and they earn their money through commissions and transaction fees. Centralized exchanges are governed by specific guidelines and policies, however, they share a common purpose of providing users with access to the most popular assets.

The volume of trading is an essential element in the success of a central exchange. The greater volume of trades means lower volatility, which reduces the risk of market manipulations that are likely to happen at a specific exchange. Centrally safe and secured exchanges have enabled major companies to establish feature-rich exchanges where users can trade, invest and reap returns with sufficient liquidity. But, since the advent of blockchain’s decentralization capabilities have made it possible for trading platforms there has been an apparent shift towards decentralized trading.

How Does the Centralized Exchange Work?

Centralized exchanges are controlled and governed by a central body, and traders should be able to trust the authority that handles trades. To understand how exchanges work let’s consider the instance for stock markets. Many people are familiar with the stock exchanges, where shares are purchased, sold and traded at a live price. A central exchange functions like an exchange for shares however it allows trading, buying and trading digital assets instead of shares.

Traders must complete KYC (know the client) verification to become registered users on any exchange. The verification generally involves ID verification, proof of identity address, address as well as biometric verification. Once the verification is completed the exchange then sends login details to the customers to login to their account, read the rulesand then begin trading in their preferred asset or currencies.

Be aware that CEX users are not able to trade assets directly with each the other. In addition, the exchange assumes the administration of funds that users put in. It then issue an equivalent quantity of IOUs to traders which they are able to exchange when they withdraw. We know IOUs serve as the basis of smart contracts in exchanges that are centralized as they’re an informal acknowledgment that reflects the debt one person owes another.

For technical reasons, central exchanges use an Order Book Method to execute trades. Order books record all open orders, allowing trading and buying trading of goods to investors. If someone wants to purchase an asset, he has to provide the estimated price to the middleman who is involved in the exchange process. When the middleman locates an individual whose request is in line with the buyer’s, it exchanges the assets and concludes the exchange between the two. Order books are not without their flaws like the lengthy waiting times for the exchange to take place and the inability of traders to verify the transaction cross-checked.

What is a Decentralized Exchange?

Decentralized exchange is an extremely popular application of blockchain technology that lets people buy and sell digital assets using a secure and transparent platform. DEXs offer the fundamental features of a central exchange and even stand out in that it allows trading of all coins accessible on the internet. This means that traders don’t have to be worried about the limited listing of coins in DEXs like they would in an exchange that is centralized.

In central exchanges, third party companies oversee the security and distribute the funds in a manner similar to stock exchanges, banks and banks. However, DEXs replace the roles of these third parties by using smart contracts precoded to assist users to make trades more easily.

What is a Swap?

Swap allows for the instant swap of two different tokens belonging to two distinct blockchain protocols without having to start the traditional exchange from fiat to crypto or token transfer. Users can swap tokens and assets directly from the authentic private keys wallet, or the trading account it self. In-wallet exchange provides many advantages to traders like the non-custodial exchange on-chain quicker transactions, as well as no fees for network connections.

The swap technology due to reasons like:

• Make a quick swap to the growing asset.
• Change to any stablecoin that you can get from an asset that is volatile.
• Hedge against risks.

How Does Swap Works?

In addition swap offers the seamless exchange of cryptos to cryptos instead of taking time and expensive changing any currency into fiat in order to purchase the desired currency. We have to agree that this method of exchange of tokens into fiat currencies can be slow and requires charges more than once when someone exchanges the token.

In taking all of these disadvantages into account taking all these disadvantages into consideration, exchanges, wallets and other trading platforms that are based on blockchain started offering swap services. With this feature, anyone can easily exchange their tokens for an alternative directly from their non-custodial or custodial wallet. To swap, users must enter the amount to be used for the swap is required and the desired trading pair. This is sufficient to perform the swap instantly and transform tokens into a distinct native token.

While the digital landscape is changing and transforming, it has created a variety of creative revenue streams which entrepreneurs and companies are recognizing. One such lucrative new commercial model that is being explored is an NFT marketplace. The idea of building an NFT marketplace is appealing to many blockchain-enthusiast businesses and entrepreneurs, for they have witnessed the traders’ obsession over NFTs. Photos, trade cards video clips, digital art domain names, as well as any other physical asset (tangible or intangible)that can be transformed into digital assets can be represented with an NFT token. The token can then be traded on NFT marketplaces.

Because of its capability to prove ownership of digital assets by permanent records on the Blockchain NFTs have been granted global recognition as a revolutionary trading organization. They are the newest elements of a trend in the crypto market, especially with collectors, artists, luxury brands , and sports franchises. The value of NFTs fluctuates like cryptocurrency, and typically the value is determined by the demand and popularity. The value of an NFT could fetch staggering values in the millions and that is the reason they have received a lot of attention from traders within only a few months.

We won’t be discussing NFT this time; instead we’ll talk about the trading platform-i.e the NFT marketplace. If you’d like to know more about NFTs in greater detail then you can read our NFT specific information here. Marketplaces for NFTs are built on several Blockchain technology platforms like Binance, Solana, Cardano, Ethereum, TRON, and more. This article will concentrate specifically on Cardano NFT marketplace development.

Cardano is a third-generation proof of-stake blockchain platform created using evidence-based techniques that are based on peer-reviewed research. It was designed to address the issues of interoperability, scalability, as well as sustainability of distributed systems. The invariability that is inherent in the technology of distributed ledgers used in Cardano blockchain secures the transactions’ information and eliminates the possibility of fraudulent transactions as well as cyberattacks on NFT marketplaces.

What exactly is an NFT market?

The name suggests it is NFT marketplace is, as its name suggests. NFT market is the one that NFT creators and investors participate in NFT buying, selling , and trading. On NFT marketplaces the most popular NFT creators include digital artists, music artists, video creators gamers, game developers galleries, art galleries as well as luxury brands and influencers. The investors who are interested are typically gamers, collectors of art, and crypto-enthuasist traders.

NFT marketplaces are free and decentralized marketplaces for artists to earn money for their work by directly contacting the general public without the need for an intermediary. That’s why artists are choosing to make use of NFT marketplaces. Another reason NFT marketplaces are preferred is because they give artists with access to both the principal and secondary market. You are aware that NFTs are unalterable and reliable evidence of ownership, which means that the individual artist, or NFT creator is always able to demonstrate his copyrights to an NFT. Even if the NFTs are traded on the secondary market, and their ownership shifts hands that original NFT creator will continue to earn royalty.

With the demand for NFTs is increasing the number of traders and investors are utilizing NFT marketplaces to purchase hold, then sell NFTs to generate profits through price appreciation. Specific NFT market places for audio/video assets Arts, Games and Real estate are beginning to emerge that provide particular audiences with more tailored features that provide the best experience for users. These special NFT marketplaces are not only used for NFT trading but are also social platforms that allow investors and creators to join to.

What are the main characteristics of an NFT market?

Cardano, Solana, Ethereum, Tezos, almost every blockchain protocol is a part of developing the NFT marketplace. The main benefit that makes up the NFT marketplace is that it’s the result of the fundamental functions of the blockchain protocol, however, the frontend of each NFT marketplace is equipped with essential features for example:

Storefront

The dashboard gives information about the collective nature about an NFT the owner the preview or price historical data.

Advanced Token Search

It supports tagging and category management to provide advanced search capabilities

Filters

It facilitates easy navigation, allowing users to filter products by method of payment categories listing status, category, and collection.

Creating Listings

Users can build and manage the database of its NFTs as well as token information like the name, tag, and description.

Bidding Option

Users can place bids on NFTs that are listed on the platform.

Wallet Integration

They are essential for storing as well as for sending and receiving non-fungible tokens.

Ratings

Gives an overview of current or most in-demand NFTs

Blockchain protocols define their NFT standards and offer developers with tools. Developers can choose between storage frameworks and frontend frameworks according to the requirements of their project or priority.

What is Cardano Blockchain?

Various blockchain protocols enable the creation of the NFT marketplace on top of it. Today, we’ll discuss Cardano blockchain. Cardano blockchain and the NFT marketplace development within relation to Cardano.

The company behind Cardano has promoted it as being the next-generation Blockchain because it was created to address the issues of interoperability, scale, and sustainability of the first and second-generation blockchains. Cardano was also the very first Blockchain that was developed using peer-reviewed research and methods based on evidence. Its output efficiency is superior and higher than Ethereum, as claimed by experts in the field.

Developers love developing around Blockchain like Cardano because of the five main characteristics it has:

• Consensus mechanism as well as protocol Proof of Stake and Ouroboros and Ouroboros, respectively are energy efficient and creates a secure transaction environment and delivers long-term performance.

• Based on evidence-based techniques, Cardano is suitable for designing high-risk applications. It can respond to new needs and developments.

• The unrivalled security of the system opens to a whole new set of markets and possibilities.

• It comes with an incentive system which provides users with a reward for their contributions as stake pool operators , or stake delegate.

• Contrary to other blockchains Cardano doesn’t use exponential energy to boost the performance or the addition of blocks.

According on the Cardano blockchain, Cardano’s brand new Alonzo Hard Fork gained traction from the moment it was released in the mainnet. This Alonzo update was launched and made available to the mainnet on 13th September, 2021. Smart contracts can be designed and deployed on the mainnet as consequence of this change.

Alonzo gives Cardano equipped with the smart contract feature. It also improves its capabilities by incorporating it with Plutus scripts that are written using a basic functional language, such as Solidity and Haskell and by allowing users to add the scripts.

With this beneficial upgrade to smart contracts available on Cardano We must be aware about the development of smart contracts using Cardano. Cardano platform. In the beginning we must understand the fundamental concept of smart contracts.

What are Smart Contracts?

Smart contracts have been pre-programmed electronic agreements that are automatically generated. They’re self-executing and cannot be modified. They don’t permit any involvement of a middleman, or the presence of third party.

We can classify smart contracts into two types:

In one instance in which you need to add the value concept of one actor (or group of players) in another player (or an entire number of actors). The representation must be of the value concept, along with the rules and conditions that apply to it, and an event that activates it. This is known as a financial contract and is best done by using a domain-specific language.

In another scenario, you’ll need to design a program or application. The application is composed of a triangle

• The client program is running on the computer.
• The server is the one that runs on a server owned by someone else (or many servers).
• Smart contracts are the piece of the code that allows decentralized operations to be conducted.

What programming languages do Cardano utilize to develop smart contracts?

Three languages are specifically designed to develop smart contracts on Cardano as described below:

Marlowe

Marlowe is a specific domain programming language (DSL) which allows users to build blockchain applications that are specifically designed for financial transactions. When compared to a Turing complete language that is, the Marlowe DSL can be described as:

• Better Security
• Assured Certainty
• Guarantee of Termination
• More reliable guarantee of accuracy of the behaviour

The following characteristics are made certain by the style of Marlowe:

• Contracts are of a specific time period, and there is no looping, recursion or looping
• Contracts will reach an end and every action is subject to an expiration date
• Contracts must be of a certain period of time for when they become in effect
• When the closing occurs there are no assets to be kept
• Preserving value

Plutus

Plutus can be described as the Cardano Blockchain’s Smart Contract platform. It allows the development of applications that connect to the Cardano blockchain. Plutus lets all programming be executed in Haskell by using one library. It allows the creation of safe applications, as well as new asset acquisition and the creation of smart contracts with the best stable secure, reliable environment. Furthermore, developers aren’t obliged to run their projects on a full Cardano node. You can accomplish these things using Plutus:

• Create new tokens in a small environment
• Construct smart contracts
• Support for scripts with simple signatures

Haskell

Haskell is the primary language of Plutus. This is the programming language that is used by Cardano for intelligent contract development. Haskell is also used to regulate Marlowe as a domain-specific programming language used to create the financial smart contracts of Cardano. Even though it has a low rank on Google, Haskell is the first option for Cardano for developing the programming language. Why does Cardano do so?

Let’s discover the philosophy behind Cardano that lies behind the decision to choose Haskell initially. The premise behind it is Haskell is able and has the capability to write code that are strong. Haskell was named after the name of an iconic American mathematician who was referred to in the field of mathematics as Haskell Curry. Curry was a pioneer in the area that dealt with functional programming, like for example, Miranda. His fascination with functional programming languages was the basis for the creation of Haskell in the year 1990.

Haskell is a functional programming language which effectively creates high-assurance code that require a certain level of verification of a formal nature. Because Haskell has a high level of assurance, it assists the Cardano developers make sure that the code they implement is reliable and accurate.

What is it that makes the Cardano blockchain different against other blockchains?

Cardano has been designed in order to become scalable, long-lasting and compatible with other systems and blockchains. architectures.

As compared to other blockchain-related protocols, Cardano is distinct in many ways. For instance, Cardano protocol development is built on peer-reviewed research. high-assurance codes are used at the most advanced levels of engineering while the program is created with Haskell as functional language.

Cardano smart contracts should be created in Plutus and IELE. which is designed to offer a greater degree of security. Plutus is an intelligent contract language written with Haskell. Haskell is well-known by developers and academics for its blend of professional and academic knowledge with basic computer science skills and programming. So, creating smart contracts using the Cardano platform is more secure and reliable than writing smart contracts using any other smart contracting language. Plutus Platform is based on the Haskell framework, which will function as a toolkit that is accessible to developers to create smart contracts. It also allows both on-chain and off-chain codes. The smart contract code used by Cardano is tested, safe, and documented through peer review and high-assurance. Additionally, this research-first method that is carried out by a properly certified team of academics and cryptography experts differentiates Cardano as well as Cardano smart contract from counterparts.

Cardano’s strength in the future lies in its ability to function as a legally binding and reliable entity that can transfer shareholder assets. The stakeholder assets of the shareholders are required for contracting parties to be able to participate. The assets of the contract are transferred in accordance with an agreement on by the parties and integrated to the agreement. But, the money that are pledged to an intelligent contract will never ever be “frozen” indefinitely. The authors can set an expiration date to ensure the money is paid back after the specified time.

A smart contract that is created and programmed with Plutus and based on the Cardano blockchain offers complete visibility to all parties participating within the agreement. If it is designed correctly an individual hostile actor is unable to engage.

Each year the Blockchain industry creates new and innovative developments that challenge the existing system and provide improvements, particularly in the decentralized finance area. Binance Smart Chain can be described as an innovative development that provides its users with a thriving and expanding ecosystem of digital assets like that which has never been seen before in the world of decentralized exchanges.
Utilizing binance Smart Chain, anyone can make and launch their own digital token. Making a BEP-20 token using the Binance Smart Chain is quite a easy task.

What is Binance Smart Chain?

It’s an architecture with two chains that allows its users to develop their own digital assets and dApps on the blockchain , and gives them the benefit of rapid trading.
The major highlights that are part of BSC are:

• EVM Compatible
• Transfer of chains across the chain
• The authority to prove stakes
• Block time = 3 seconds

BSC operates in parallel with Binance Chain and allows Smart Contracts for tokens on the Binance blockchain. A new staking system was also added to BNB which is one of the top cryptocurrency. BSC gives its users:

• Low transaction fees
• Defi cross chain mechanism that improves the interoperability of defi
• high-performance network with the ability to create blocks every 3 seconds
• an evolving ecosystem of millions of users
• An incredibly solid Binance ecosystem that finances and bootstraps a variety of defi projects

What is the standard for the BEP-20 token?

BSC tokens comply with the BEP-20 standard that is identical to ERC-20. ERC-20 Ethereum standard. Because BEP-20 as well as ERC-20 are nearly identical, they are suitable for both. Binance Smart Chain (BSC) is a fork from the Ethereum mainnet.
Token standards provide basic functions for tokens like transfer of balances, returning balances ownership of tokens, looking at the ownership of tokens, etc. It is vital to know that BSC tokens can be swapped for the Binance Chain which is compatible with the standard BEP-2. Transactions that use these tokens on chain require an expense payment in BNB. It’s like an incentive for validaters to protect the network.

How do I deploy the BEP-20 token?

After successful compilation Move to deployment by pressing the icon that is below the icon for the compiler. Set the environment to injected web3 as we are making use of Metamask for deployment. Make sure it is it is the SampleBEP20Token option is selected from the Contract dropdown. Now, we’re ready for the deployment of our SBT token. Click the Deploy button, an alert from the metamask screen will be displayed to confirm the deployment. Press Confirm to deploy your token.
When the transaction is completed The contract’s details as well as the logs will be displayed under the Deployed Contracts section. The SAMPLE BEP20 TOKEN option in Deployed Contracts lets you view the variables and methods that are public that aid in testing the deployment.
The Transfer method permits transfers of funds from one account to the other. After entering the address of the recipient and the amount, click on the transfer button. Metamask popups will prompt for confirmation. Click Confirm to initiate the transaction through. After the transaction is successful its status and the details will be displayed on Remix IDE logs.
Following the steps described above, you are able to deploy the number of tokens you like.
Follow the steps below to determine your SBT Balance of the receiver’s wallet via Metamask:

• Click to click the Add Token button at the end of the Metamask account.
• Input the address of the token contract. The token symbol and the token name will be detected automatically. Click on Next.
• The balance of your token will show when you click Add Tokens to add the tokens to the Metamask account. When the token has been added, it will be displayed within the asset section on the Metamask account.

Like every other technology, blockchain also has potential for improvement. It’s interesting to note that new solutions-oriented blockchain protocol are in the process of being designed to address the shortcomings that the tech has. For example, Polkadot resolves the issue of interoperability between blockchains. Chainlink facilitates communication between off-chain data and on-chain APIs and data servers. Hathor enhances scalability and lowers transaction costs.

In addition, every new blockchain technology has particular strength, which further increases the efficiency of blockchain technology and makes it more flexible for use in real life.

For this post, we’ll look at a different blockchain-based protocol, called Phala Network. It can be described as a cloud-based computing platform that can provide security in blockchain smart contracts, DeFi and dApps. Phala attempts to address issues of trust within the cloud computing.

What is the significance of confidentiality when it comes to smart contracting?

Blockchain is distinctive because it is an open ledger with a distributed system that records transactions in a safe and transparent manner. Each transaction is recorded publicly. Therefore, anyone can confirm it, however, nobody can alter the information. Blockchain’s transparency Blockchain is a groundbreaking feature that enhances security and user autonomy.
However, some businesses may also possess sensitive or private information they don’t want to expose for all to see. For instance, traders in the stock market are keen to make their information available, but aren’t keen on revealing their orders or their positions. Due to the privacy concerns, those privacy-related DApps on Ethereum are not in compliance in accordance with General Data Protection Regulation. In the end, they could be blocked by the European Union.
Certain blockchains are not appropriate to process confidential information. Bitcoin and Ethereum aren’t. The inability to handle sensitive data or sensitive information for business restricts the use of the Blockchain because it causes trust issues.
A variety of methods address the issue of confidentiality and privacy in Blockchain However, the solutions are only applicable to cryptocurrency and do not expand to smart contracts.

What is the Phala Network?

Phala Network is a new method that aims to provide the security of smart contracts using specialized hardware Trusted Execution Environment (TEE). Its goal is to offer privacy-preserving smart contracts to meet four goals:

• Secure the privacy of managed apps.
• Give computing power that is on level with existing cloud services.
• Keep the security and reliability of Blockchain. All computing operations performed on Phala are secure.
• Interoperable cross-chains without compromising security.

In our insights on blockchain interoperability that cross-chain communication is essential for any blockchain-based smart or dApp, otherwise, its usage in the real world is extremely restricted. The confidential contracts that are powered by Phala can be interoperable, and can be used to interact with other private contracts in a symbiosis.

Phala Blockchain is built upon Substrate which is interoperable to the Polkadot ecosystem. (Read for more information regarding Polkadot interoperability) Additionally, Phala is a Parachain of Polkadot and, by design the Phala blockchain has the capability of being an interoperable blockchain. But, Phala takes Interoperability a step higher by facilitating the transfer of assets to another blockchain while maintaining confidentiality.

What are the major benefits that come with Phala Network?

• Phala is protected against attacks at the system level because sensitive information will be processed and processed by TEE which is an isolated processor
• Only authorized key-protected actions are permitted on the network.
• All off-chain and on-chain communication is encrypted from beginning to end.
• The code off-chain and execution is verified on chain.
• A substrate-based parachain that is akin to Polkadot, Phala is designed to be interoperable and cross-chain compatible.
• Since it is interoperable, Phala is able to offer computing capabilities to other blockchain-related applications.

Everything you need to know about Hathor NetworkOne of the newest competitors in the field of crypto is Hathor(HTR). It is a blockchain-based proof-of-work digital platform specifically designed for light financial contracts and transactions. Since its introduction in the year 2020, it has been the subject of attention due to its innovative and original structure. Hathor Network has put forward small value propositions to solve the issues of scalability and maintenance of decentralization, both of which are commonplace in distributed ledger systems like the ones for Bitcoin or Etheruem.

What is the reason why something similar to Hathor necessary?

Within a short time after its launch bitcoin’s blockchain was regarded by the business community as a breakthrough technology to meet businesses’ needs. However, while examining it for real-world applications, the bitcoin’s initial design was found to be limited in both capacity and application. As transaction volumes increase on the bitcoin blockchain, it begins to face issues on several levels including storage, bandwidth on the network decreases as well as the consumption of computer power and power to prove of work significantly increases. Mining is restricted to a handful of sophisticated miners. The value of bitcoin decreases gradually. Another issue that is common is excessive transaction costs.
The structure of the Hathor Network overcome these kinds of limitations? If yes, what exactly is it that it does? What are the unique features that aren’t found in other popular blockchains?
This article provides a deep-dive into each aspect of Hathor with a particular focus on the analysis of its comparison with other blockchains that are popular.

What is Hathor Network?

Simply put, Hathor can be described as a user-friendly and scalable distributed ledger that can be used to facilitate simple financial transactions and contracts. It also functions as an open platform for consensus, but its design is unique as it is a hybrid platform that was created by mixing Directed Acyclic Graph (DAG) and blockchain technology. In essence, it’s an electronic blockchain within an DAG and both are interconnected. When the volume of transactions is minimal and the blockchain is secure, it will be able to protect while when the amount is increased, DAG takes over.
This hybrid architecture provides the ideal environment for a variety of scenarios, especially when the need for high-scalability is required. What is the way that DAG and Blockchain when combined can improve the scalability and performance of Hathor’s network Hathor network is to be explored in the near future. Prior to that, let us define some of the characteristics of Hathor that differentiate it from other platforms.

What is it that makes Hathor different?

The creators of Hathor have described it as a “Scalable distributed ledger designed for real-world use. It is created to address many of the issues that are prevalent with current mainstream blockchains like:

• The high cost of transactions for transactions in the Bitcoin Blockchain is one of the most discussed problems. However, transactions made through Hathor are free. Hathor network are free that means that the cryptocurrency is able to be traded and transferred without having to pay any charges.
• Hathor is far more flexible in comparison to Bitcoin or Etherum network, meaning that even when the volume of transactions increase the security and efficiency of the system won’t become affected. It doesn’t mean that the it doesn’t have a central coordinator at any given point in time. Hathor Network is totally uncentralized ledger, and yet it is able to provide long-term security as transactions increase in volume.
• The Hathor network permits merged mining using Bitcoin as well as Litecoin. This means that Bitcoin and Litecoin mining users are able to be part of the mining process of HTR and, by doing so they won’t lose profits made through Bitcoin as well as Litecoin chains. In addition, miners are offered incentives through HTR tokens for free of cost. The miners feel safe and encourages them to work to earn HTR cryptocurrency.
• In just a couple of clicks, anyone can make customized tokens (digital tokens) via the Hathor Network. The official website states that 13-year-olds can make an account to play with.
• The Hathor network is a part of ‘atomic swaps. The advantage for this function is that it permits distinct tokens to be exchanged within the same transaction which improves the efficiency of the network.
• Another significant aspect of Hathor worth mentioning includes the Nano Contract. Nano Contracts are in development currently. They are similar to smart contracts but with smaller computation power and costs. Therefore, it is an alternative to this smart contract. In addition, by incorporating built-in automatic swaps, nano-contracts are designed to reduce transaction costs.
• As mentioned previously the design for Hathor’s architecture Hathor network is unique and distinct. It is constructed by intertwining both blockchains along with DAG technologies to address the issues of scaling and maintenance of decentralization that are prevalent on other ledger distributed networks. According to various sources, there isn’t any other publically-known project that is currently working on this sort of solution.

Here defining how the novel architecture of Hathor functions and achieves high scalability.

Since Ethereum was introduced into the world of blockchain by its appearance in the year the year 2015 Vitalik Buterin, a Russian-Canadian programmer has created new applications decentralized (dApps). But, the success of Ethereum is significant due to the development of smart contracts.

Many think they are an entirely new concept that was invented by Ethereum, the Ethereum Blockchain Platform. Smart contracts actually date in 1996 when the computer researcher Nick Szabo coined the term “smart contracts” and explained the concept as follows:

I refer to these contracts as “smart”, because they are more useful than their paper-based inanimate ancestors. The artificial intelligence or artificial intelligence are implied. Smart contracts are a set of agreements that are defined in digital format, and includes protocols that allow the parties to fulfill their promises.

His work was later a source of inspiration for other researchers and scientists and also Vitalik who created Ethereum.

Before we get into the creation and implementation of Ethereum smart contract it is crucial to know how to use the Ethereum platform and how it functions.

Ethereum as it is a Blockchain Platform for developing decentralized applications

Blockchain platforms let developers develop and manage smart contracts. Ethereum is also among Blockchain platforms which are able to execute any kind of code to allow you to run any type of program using Ethereum.
The Ethereum Blockchain is a possible distributed infrastructure that allows the completion of projects with smart contracts.

Create your cryptocurrencies

With Ethereum as a platform, you can make an exchangeable token could be used to create an entirely new currency. Tokens created using the Ethereum platform make use of an API for coins that is standard to work with any Ethereum cryptocurrency wallet.

Create virtual organizations

You can create an intelligent contract to create an organization based on blockchain. Then, you can add additional members to your company and set up voting rules. The members of your group can vote , and if the number gets to the minimum number of votes the smart contract will be executed completely.

Build dApps

Ethereum lets developers develop reliable and secure decentralized applications that remove middlemen in addition to offer transparency.

Raise funds

Additionally, you can make use of Ethereum smart contracts to raise funds. With Ethereum you can draft an intelligent contract with an expiration date. If you do not meet your objective then all donations will be returned to donors with no conflicts or commissions.

How does the Ethereum Blockchain Platform performs Smart Contracts?

Before we discuss how to build an intelligent contract using Ethereum, or the Ethereum platform, it is essential to know what is the Ethereum blockchain , and the way it manages smart contracts.
Therefore, let’s look at the context of execution first.

Ethereum Virtual Machine (EVM)

The goal for EVM is to function as a runtime environment to smart contracts created on Ethereum. Imagine it as a supercomputer global which executes all smart contracts.
The name suggests that Ethereum Virtual Machine is not physically based, but is an online machine. The capabilities of EVM is limited to virtual machines. For example, it can’t make calls that are delayed on the internet or generate random numbers. It is therefore as a basic state machine. Writing assembly language programs is not logical Therefore, Ethereum required a programming language to run the EVM.

Gas

The Ethereum Virtual Machine gas is a measurement unit that is used to assign charges to transactions that are made with the use of a smart contract. Every computation that occurs within the EVM requires a certain quantity of gas. The more complex the calculation is, the more gas is needed to run these smart contracts.
Transaction fee equals Total cost of gas used*gas price

Solidity

Solidity is a smart-contract programming language based on Ethereum. Based on the EVM and is similar to the object-oriented language that relies on methods and classes. It lets you perform any kind of computation, however it can be used to transmit and receive tokens as well as keep track of state. In terms of language, Solidity is greatly influenced by C++, Python and Javascript in order to help developers comprehend its syntax in a short time.
It is best to understand the fundamentals the Solidity programming language in order to create the Ethereum Smart Contract.

What is a Smart Contract?

The Smart Contracts are the basis of business logic or a method by which all transactions on the Blockchain occur. The purpose of the smart contract is to fulfill the common contractual requirements, such as creating your an own cryptocurrency on Ethereum. We must develop smart contracts that follow every calculation for our token will take place.
It’s a standalone script that is written using Solidity and then converted into JSON and distributed to a specific account on the Blockchain.

A Ethereum smart contract (smart contract) is form of account which is run by a program that includes software and data acquisition. It is stored at a specific location in the Ethereum blockchain.

As a kind of Ethereum account Smart contracts can store the balance of transactions and transfer them through the network. However, it is notable that they’re deployed to the network and not controlled by the user. They operate according to how they are programmed. users are able to interact with them by sending transactions in line with specific functions of smart contracts.

Just like a regular contract, smart contracts define rules. But the difference lies in the execution. Instead of simply making rules smart contracts implement them with code. Additionally, the interactions made that are made with smart contracts are permanent and cannot be canceled in default.

The complex blockchain software such as Ethereum are extremely exploratory. There are always changes and when new loopholes or bugs are discovered or discovered, innovative best practices get brought into the market. Thus the security landscape keeps changing and can differ from one point to another.

General Best Practices for Ethereum Smart Contracts

Every kind of best practice are essential for ensuring that the smart contract will defend itself from security vulnerabilities and bugs in terms of security. Certain of these best practices depend on the approach and mindset that the developer uses for protecting the smart contract.

1. Be prepared to fail.

Every important contract is vulnerable to errors. Therefore, you need to be prepared for the occurrence of errors and your contract must be able to respond to these. You can do so by:

• Stopping the contract or breaking the circuit’ if problems occur.

• Designing a successful upgrade strategy that includes improvements and strategies to address loopholes, bugs and loopholes.

• Effectively managing amount of money that is at risk by limiting its maximum amount of use and governing the total amount.

2. Make sure you are careful when rolling out.

A careful rollout can allow you to find and eliminate problems before entering the production phase. This can be accomplished by:

• Conducting thorough tests on contracts.

• The contract is being rolled out in stages, with a gradual increase in testing and usage in each phase.

• Offering bug bounties even before the testnet’s alpha versions.

• Testing to discover every new attack pattern.

3. Keep the contract simple.

If you design your contracts to be complicated they are more susceptible to chances of mistakes and bugs. Therefore, keeping them simple is the most effective method to minimize the chance of making mistakes. Keep contracts easy by following these guidelines:

• It is important to ensure you’re using a contract that’s straightforward.

• If you can, make use of tools or code that you’ve written before.

• It is possible to modularize the code to reduce the number of contracts and functions tiny.

• Make use of blockchain only for areas of your system that require decentralization.

• When possible, give priority to simplicity over efficiency.

4. Stay informed and stay on top of any new developments.

You should always be current on any security advancements or updates. You can do so by:

• Always check your contracts for any new errors or bugs.

• Open to new security methods.

• When you use libraries or tools and library, upgrade to the latest release as fast as you can.

5. Be aware of blockchain properties.

Anyone with enough experience in programming are able to master Ethereum programming easily. But, they should be aware and alert to specific pitfalls and properties of blockchain by:

• Be cautious when making contracts that are made outside of the organization as they could be malicious and alter on the control flow.

• Keep in mind that anyone could also access private data contained in smart contracts.

• Being aware that attackers could deliberately make public events appear as they are not public.

• Be aware that in a blockchain system, time stamps are not precise and miners may alter or alter the time of an operation’s completion by the span of a few seconds.

• Be aware of the gas restrictions for block gas and the cost.

• Be aware of the methods used for random numbers on blockchains is generally game-like and not a problem.

6. Take into consideration the tradeoffs that are fundamental to your situation.

Take into consideration thFrom the standpoint of engineering software, a perfect smart contract should be modular, have upgradeable components and reuse code, without duplicates it. But, from a security architecture’s perspective an ideal smart contract could be able to follow the same design. So, when evaluating the security and the structure that you will be using for your it is essential to strike a balance between these two aspects.

Defi has emerged as a market that is saturated from all aspects, and is based on the possibility of crowdsourcing additional funds through the launch of hundreds of projects within one space, with no visible rules. There are a myriad of loan protocols, decentralized exchanges and platforms of yield farming. Each newly created Defi project is now focused on being different from the others through all ways. In the case of Injective Protocol Injective Protocol, it has developed a plan to target the derivative market using an scalable and decentralized strategy. It’s hard to overlook an organization that boasts of having unlimited acces to DeFi markets with no restrictions, and by utilizing backing from major industries such as Pantera, Binance, and CMS.

What is an Injective Protocol?

Established in the year 2018 by Eric Chen and Albert Chon in the year 2018 Injective Protocol is a decentralized derivatives exchange built on Ethereum supported by an advanced layer-2 solution. The system of Injective Protocol that has a layer-2 solution backup enables investors to quickly and securely access DeFi market. Injective Labs unveiled its first product as the first completely decentralized exchange system for DeFi in the month of April in 2020. The initial goal of the development team was to eliminate the restrictions of the DEXs in the past which restricted users due to relying on trading in order books and excessive latency. They also had insufficient liquidity, and other centralized design.

When we speak of Injective Protocol, we’re not just talking about the DEX which allows you to transfer tokens and yields from farms. We’ll instead explore an DEX which focuses on the market for derivatives. Injective Protocol aims to deliver the benefits of decentralized futures, margins spot trading, permanent swaps to investors in DeFi. Every component that supports the DEX, according to Injective Labs, is constructed in a censorship-resistant, public, and entirely trustless manner. Injective Chain, Injective Exchange along with Injective Futures Injective Futures platform are the three primary components of the project.

Motive

Injective Protocol visions a newly built economy that is decentralized in its nature. The goal of this idea is to create the most secure and secure system for exchange, payments and the transfer of money. Injective is a company which allows crypto exchange and makes the crypto as a public utility that is decentralized in the sense of. The solution to exchange cryptos offered to users by Injective Protocol has assisted the users, giving them and their communities with an advantage in the world of exchange. The forex trading on the blockchain that is cross-chain based as well as derivatives and futures permit participation from any and everyone around the globe with the aid by Injective technology.

Injective Protocol is creating an exchange model that has the potential to change the way trade is conducted in the manner it is currently happening through technological advancements, which accelerates trade and settlement execution speed in a swift and decentralized way without authorization or any censorship.

What is the issue that this Injective Protocol solve?

Injestve Protosol is a teshnologu designed to address the issue of third parties in trading by rroduing the right sequence however, the orders are processed sesurelu and without collision barriers. It was invented to maximize the benefits of DEX liquidity and also eliminate the requirement for third parties in order to coordinate trade transactions within the exact block. It also permits rogue traders to choose an order that is suitable for using it without knowing the particulars of trade orders that belong to other traders. This prevents front-running and guarantee that an abundance of additional orders are fulfilled without difficulties. Injective Protosol is designed to prevent front-running and ensure that orders can be Injective Protosol is made to be able to meet the aggregation agreement of most DEX to ensure liquidity by matching orders to allow for the flexibility and effectiveness.

The rise of the cryptocurrency era has brought about technological advancement and legal/regulatory tangle. Startups have begun making creative use of cryptocurrency in the form of an Initial Coin Offerings, to create and provide new crypto tokens that can be exchanged for fiat currencies.

Due to its decentralized and unduly regulated nature, cryptocurrency has created legal challenges for various law enforcement authorities, including, US securities law. The most important question is whether cryptocurrencies is covered by US Securities Law.

Many schemes have been developed to raise money to avoid applying for securities law.

The courts have looked into these schemes to determine if they are investment contracts as per Federal definition.

Howey Test was devised to determine if securities are subject to certain rules regarding disclosure or registration.

What is the Howey Test?

One of the most important cases involving the investment contract definition is in the US Supreme Court, SEC v. W.J. Howey Co. under Howey Test declares the definition of an investment agreement is that is a scheme, contract or arrangement in which the participants invest their money in a typical business and hope to earn profits only through actions of an third-party or promoter.

Additionally The U.S., SEC has stated that cryptocurrency that meet the Howey Test are securities and are subject to regulation for securities in addition.

Supreme Court has created the “Howey Test” to identify the extent to which certain transactions are “investment contracts.”

If the transactions qualify in nature, they will be considered securities in the Securities Act of 1933 and the Securities Exchange Act of 1934.

We must have a good understanding of the concept “Security” before discussing the Howey Test in more depth.

How do you define security?

The Securities Act of 1933 and the Securities Exchange Act of 1934 were both enacted over 100 years ago to establish an important portion of U.S government’s strategy for dealing in financial regulatory.

According to section 2(a)(1) in the Securities Act of 1933, transactions that are deemed to be “investment contracts” are referred to as securities, such as books, promissory note bonds, stocks and promissory notes.

Transactions in investment have a significant influence on the way that the finance world views and interacts with securities.

Therefore, it is essential to establish a consistent method to determine whether the transaction is deemed to be investment contracts.

The securities offered are required to be registered with Securities and Exchange Commission (SEC) in the US.

An entity that provides securities that aren’t exempt from registration, must register them.
