Up until December 28th, 2022, Ethereum is now the second largest cryptocurrency in the market with its market share of 17.4%, the top being BTC with 38.2%.

Ethereum couldn’t get to this point if it weren’t for its vibrant developer community. And the Ethereum Virtual Machine (EVM) is the core of that.

Unlike Bitcoin, which all it has is a distributed ledger for cryptocurrency transactions. Ethereum has EVM which allows developers to build dApps using the ledger and to execute smart contracts using the language Solidity when every new block is generated.

It is essentially a virtual computer or a runtime environment simulated by software standing between the nodes and the smart contracts, which has much more power than simply recording transactions, like BTC.

What is EVM Compatible Chain?

Before we ask what EVM compatible chain is, the more important question is why EVM is compatible at all.

According to Footprint Analytics, Ethereum occupies 67.45% of TVL in all chains apart from BTC, despite that, Ethereum users still suffer greatly from the slow block generation rate (13s per block as opposed to 400ms per block on Solana) and the high Gas Fee on L1.

Many developers are now looking for a better alternative to launch their dApp with lower Gas Fee and faster transaction rate, yet still has the privilege of accessing the vibrant Ethereum community, that is where EVM compatible chain comes in.

EVM-compatible chains like Polygon, BSC, and Avalanche essentially provide developers with a familiar and well-established platform for building decentralized applications. Because the EVM has been widely adopted and is well-understood by the developer community, it is relatively easy for developers to build on an EVM-compatible chain.

And from a technical perspective, developers don’t have to rewrite smart contracts on EVM-compatible chains since a similar runtime exists already. They can just deploy their code and enjoy the much lower Gas Fee as well as faster transaction speed on the go and fastly test out their ETH dApps on other chains.

Additionally, because EVM-compatible chains are interoperable with Ethereum, they can potentially benefit from the network effects of Ethereum and tap into its user base and developer ecosystem. This can make it easier for developers to build and deploy their applications, and for users to interact with these applications.

Some of the Famous EVM Compatible Chain

Polygon (formerly known as Matic Network)

Polygon is a layer 2 scaling solution built on top of Ethereum. It allows for faster and cheaper transactions while still being compatible with Ethereum's EVM.

The main advantage of Polygon is its low transaction fees, which make it suitable for applications that require frequent and small transactions.

Unlike many other EVM-compatible chains, Polygon’s position is more of a supplement to Ethereum rather than a mere replacement. They are actively building on several different Ethereum scaling solutions like ZK Rollup, yet also emphasize Defi (Quickswap) as well as NFT collaborations with Web 2 companies like Starbucks, Meta, eBay, and even Mercedes.

It is one of the EVM-compatible environments that are actually really rich and diverse due to its early start and fast movement.

Avalanche

Avalanche is a layer 1 EVM-compatible chain that allows for fast and secure transactions. It uses a unique consensus mechanism called "Avalanche Consensus" which allows for high transaction throughput and low transaction fees.

Compared to many other EVM-compatible chains, Avalanche is attractive to Defi builders due to its ability to allow users to transfer ERC 20 tokens between Ethereum and Avalanche, attracting many dApps like Sushiswap to join the ecosystem. It is also a chain with very high TVL, which is also a reason people find it bullish

Binance Smart Chain (BSC)

BSC is a layer 2 scaling solution built on top of Ethereum. It is designed to be compatible with Ethereum's EVM and supports the same programming languages as Ethereum.

The main advantages of BSC are its fast transaction speeds and low transaction fees, which make it suitable for high-volume transactions and Defi applications.

However, this high volume of transactions comes with a cost of centralization, which is a textbook case for the impossible trilemma problem. Under its PoSA consensus mechanism, there can only be 21 nodes verifying the whole transaction.

But despite that, the reliability of Binance company and its vibrant community is still attracting more and more users to the BSC chain.

Fantom

Fantom is a decentralized platform that aims to provide fast and secure transactions for a wide range of applications. It uses a unique consensus mechanism called "Lachesis Consensus" which allows for high transaction throughput(more than 10,000 transactions per second)and low transaction fees.

Fantom also suffers the same problem of centralization as BSC does, yet the cheap Gas Fee and the generous incentivization program still draw many developers to the ecosystem.

Final Note

EVM chains are not the only way of embracing the Ethereum Virtual Machine, there are also other ways like building a separate environment on a non-EVM chain to allow EVM developers to join, such as Moonbeam on Polkadot, Aurora for Near, and so on.

Also, despite the trend in different chains of embracing Ethereum Virtual Machine, there are still chains like Solana and Aptos that operates in their own way and still worked out really well, we will try to address these topics in the articles to come. Stay tuned and we will see you guys later!

Conclusion

Despite the bearish market, web3 developers are more active than ever. In fact, in 2023, we predict that developer infrastructure will be the new trend. Thousands of developers are building in Web3 right now. They’re experimenting with new ideas, building new projects, and bringing new utilities to the users.

New technologies in blockchain are still emerging, and products that provide services to developers and builders are the future. There are a variety of projects emerging from the Solana Hackathon, including developer incentives, sdk and developing tools, either of which will help more people join the crypto world. So if you’re looking for a way to get involved in this exciting industry, developer infrastructure is the way to go!

Since then, crypto investors and web programmers have been hovering between Web2 and Web3, with others learning more about blockchain and dApp building.

As a new web developer or Bitcoin user, you are probably stuck between using traditional software or non-coded applications. To begin with, non-coded or low-code smart platforms allow blockchain developers to create the technology easily. These techniques increase productivity since crypto investors can accomplish more within the shortest time. dApps also allow end users to deploy their blockchain technologies quickly.

The question is, should one become a blockchain developer to create their dApp? The simplest answer is NO. Although, building your dApps without being a blockchain developer seems like a straightforward task, especially if you understand all the basics involved. Hence, this article gives a definitive guide on how to build a dApp without in-depth blockchain knowledge.

What Is a Dapp?

Just by breaking it down, dApp stands for decentralized applications (d for Decentralized). These are applications that do not rely on centralized backends running in AWS or Azure that power traditional web and mobile applications.

Instead, they interact directly on a blockchain in form of smart contracts and mobile or web apps. Blockchain nodes or smart contracts do not need a leader who can defeat their purpose of being independent or decentralized. Rather, all blockchain transactions on decentralized applications are processed by random nodes through Proof of Work or Proof of Stake.

dApps come in various forms, including Web3 websites, Web3 mobile applications, and Web3 games. These forms incorporate web or in-app authentication to enable users to log in. However, since most internet users are familiar with Web2 authentication, it was wise to introduce dApps that allow Web3 authentication via email. Other dApp builders also boost Web3 user onboarding by allowing Web3 social login.

Key Decentralized Application (dApp) Features

Crypto Wallet

The most essential part of a decentralized application working on a blockchain is a crypto wallet that allows the user to connect to the app. The wallet also allows customers to receive bonuses and rewards as virtual currency, cryptocurrency, or non-fungible tokens (NFTs) . Therefore, anyone planning to create a dApp should also learn how to build a crypto wallet.

Tokens

dApp users also need tokens to access different software options. The primary purpose of tokens is to fuel any transaction running in the software’s background. dApp or blockchain users can also create crypto tokens to boost their Defi apps, increase app development capital, or for other goals.

Transaction-Based Actions

dApps also need specific actions to perform, just like traditional or centralized apps. However, the only difference is that dApps rely on transactions to survive. dApps also have smart contracts to execute transactions and all transactions are done without third-party interference. Users also have the power to propose and vote on all changes that are implemented on all dApps.

How To Build a Decentralized Application

As stated earlier, you don't need to become a blockchain developer to build your decentralized application. That is because dApps work on smart contracts and front ends.

Smart contracts, in this case, refer to codes that blockchains depend on to execute a transaction when certain conditions are met. On the other hand, the front ends are traditional web or mobile applications with intuitive interfaces that allow blockchain users to interact.

dApps also need backends or web applications that connect to smart contracts via APIs and oracles. These backends aggregate analytics and allow users to run reports and manage some dApp aspects. That said, while there seem to be a lot of juggles involved when building a dApp, newbies can approach this challenging task by focusing on the five main steps discussed below.

Steps To Building a dApp

1. Building A Smart Contract

A smart contract or a combination of smart contracts is what carries the logic of your dApp. When creating a smart contract, you should ask yourself the specific action you want your dApp to perform automatically, based on the blockchain consensus. Is it going to be a simple transaction, a string of algorithm computations, or something complex? All these questions determine if the smart contract will execute an operation automatically.

If you also plan to create a cross-chain dApp, you need to think about a combination of smart contracts. That is because a smart contract works on a single blockchain. That is also why most dApp creators choose Ethereum since it supports cross-chain transactions, has many users with already-enabled crypto wallets, and allows faster onboarding.

Need Help?

Though, if you want to introduce a new crypto wallet, you can choose other chains since they also support smart contracts and users are not even concerned with which blockchain your dApp is built on. Another reason to create a new crypto wallet or smart contract is to harness the massive audience that seems unfamiliar with the blockchain network.

2. Creating Front Ends

Just like smart contracts, decentralized applications cannot also work without front ends. Although the primary purpose of decentralized applications is to eliminate third parties, they should not be very different from normal apps that users interact with every day. That means you should also create appealing and intuitive front ends or user-facing mobile or web applications.

Front ends also minimize effects on the User Interfaces (UI), even though user actions can trigger some smart contract performance on a chain rather than connecting them with a central server.

Remember that initiating a smart contract function from a user-facing UI can take some time since blockchain transactions are not executed immediately. Thus, you can include some professional animations on the front ends to notify users that their transactions are still in progress until the action is verified.

You can also allow users with existing crypto wallets to onboard easily by integrating with services such as Mirror World Smart Wallet that allow users to connect their wallets. Moreover, make all features visible from the user end to allow them to explore your solutions before connecting their wallets.

3. Creating A Centralized Back End

A private web solution or a centralized back end is essential when creating an Ethereum dApp that requires massive data storage or if you plan to run reports or any other technical operation that is beyond on-chain transactions.

A centralized back end has an admin portal that connects to smart contracts and front-end apps. The connection allows users to offer additional features to you as the developer. You can also integrate these new features to run your dApp and its users.

Creating a backend is what makes your application decentralized. Although most people consider it the hardest part of the puzzle, it is easy to build since you only use all the details inside your applications that relate to smart contracts. The back ends also enable the front ends to reflect the live on-chain data.

4. Running A Rigorous Test

Before releasing the dApp for users to download and install on their desktops or mobile phones, you should first test it rigorously. That means you should start by passing your dApp through a thorough quality assurance (QA) testing process to check its functionality.

Doing so ensures that your application provides the best experience to the end-user and everything runs as intended. QA testing also checks the speed at which the application runs on the user’s device.

Testing front ends is often a straightforward task since it relies on a standardized protocol. Contrary, testing a smart contract is unique since you will need to verify its performance using a testnet. Remember that once you deploy a smart contract to the mainnet like Ethereum, you cannot remove any bug left in the dApp.

5. Deploying And Maintaining Your dApp

Although deploying your dApp should come as the final step, the truth is that application maintenance is a continuous process. You will need to update some things on the front end regularly, even though some features such as smart contracts will remain intact since a blockchain app is immune to changes.

After testing all the dApp's functionalities, you can deploy it by uploading mobile apps to App Store and Google Play Store, switching the back-end portal to a live production environment, and adding smart contracts to the blockchain.

Conclusion

Building a decentralized application is a comprehensive topic that requires one to learn about all the peaks and falls involved. For instance, while the three main components of a dApp are frontends, smart contracts, and backends, there are still more to learn such as the dApp architecture, smart contract coding, and voting.

Also, if you are interested in building a dApp without the need to become a blockchain developer, you should start with simpler projects that do not deal with smart contract combinations. You should also decide between Web3 games, websites, and mobile dApps, based on your primary need for decentralized software. Luckily, the internet is now full of dApp developing tutorials, and getting should never be a hustle anymore.

What is A MPC Wallet?

Unlike traditional wallets, which rely on a single user to generate and manage the private keys that grant access to the funds, MPC wallets use a combination of multiple private keys to provide enhanced security and protection against theft or loss.

At the core of a MPC wallet is the concept of multi-party computation, a cryptographic technique that allows multiple parties to jointly compute a function without revealing their inputs to each other.

In the context of a MPC wallet, multiple private keys are generated and distributed among different parties, who must all agree to sign a transaction before it can be processed on the blockchain.

This means that even if one of the parties is compromised, the funds in the wallet remain safe as long as the other parties do not agree to sign the transaction.

Security

One of the key benefits of using a MPC wallet is that it provides an additional layer of security against hacking and other forms of cyber attacks. Because the private keys are distributed among multiple parties, a hacker would need to compromise all of them in order to gain access to the funds in the wallet.

This makes it significantly more difficult for attackers to steal the funds, as they would need to overcome the combined security measures of multiple parties.

Another benefit of MPC wallets is that they allow for greater control and flexibility over the management of digital assets. With traditional wallets, the user is solely responsible for managing their private keys and securing their funds.

This can be a daunting task for many people, and a single mistake or oversight can result in the loss of funds. With a MPC wallet, however, the private keys are managed by multiple parties, which can help to reduce the risk of human error and improve overall security.

Share Mirror World Smart SDK

Zero-Trust

In terms of asset management efficiency, MPC technology allows parties to collaborate on a computation without having to trust each other. This can be useful in situations where the parties may not know or trust each other, or where there is a risk of malicious behavior.

For example, in a distributed ledger system, multiple parties may need to jointly compute a function in order to reach a consensus on the state of the ledger. Without the zero trust feature of MPC, the parties would have to trust each other to not collude or cheat in order to reach a correct consensus.

With MPC, however, the parties can securely compute the function without having to trust each other, which can help to ensure the security and integrity of the ledger.

In conclusion, a MPC wallet is a highly secure and flexible way to store digital assets. By leveraging the power of multi-party computation, it provides enhanced protection against hacking and other forms of cyber attacks, while also offering greater control and flexibility over the management of funds.

If you are looking for a secure and reliable way to implement crypto wallets into your application or projects, MPC wallet is definitely the type of technology you want to look into.

Processing Architecture

Key differences we see in in these two networks lines within the underlying the procession architecture. The EVM is a stack-based machine, where each instruction pops two operands from the stack, performs an operation, and pushes the result back onto the stack. This makes EVM execution very predictable and easy to reason about. However, it also makes EVM execution relatively slow.

Leave a comment

Solana's architecture is radically different. We have a register-based machine, where each instruction pops one operand from the stack and pushes the result back onto the stack.

This makes Solana execution much faster - we can process tens of thousands of contracts in parallel on modern hardware. The Solana runtime is able to process tens of thousands of contracts in parallel because it uses a data flow architecture. This means that contracts do not need to wait for each other to finish before they can execute. Instead, the runtime assigns each contract a set of data and instructions that it can operate on independently. This allows contracts to be processed in parallel, which results in a much faster and more efficient blockchain.

Account System in Solana

In Solana, Accounts are any place where data is stored on the blockchain. What makes the blockchain unique compared to other blockchains like Ethereum is how this data is stored and managed. There are three different account categories:

- Program Accounts store executable code and the equivalent of Ethereum smart contracts.

- Storage Accounts store the data connected to programs.

- Token Accounts track an account balance of tokens and allow for transferring or receiving tokens between accounts.

Stateful V.S Stateless:

The difference in Solana and Ethereum is that in Solana, the program is separate from the data/state of the program, while in Ethereum, the smart contract and the data of that smart contract are located in one location on the blockchain.

EVM is a stateful network in that it includes state data such as the current state of the contract, the account balance, and the storage at each address. In other words, each address is associated with what these states mean, at any given time - for instance, there can only be one "canonical" state from block to block in the chain (and every new input makes this determination).

Join Smart Devs on Solana

Solana's stateless design means that contracts do not need to keep track of their own state. This reduces code complexity and improves scalability. It also makes contracts easier to debug, since you can simply look at the account's contents to see what is going on. This difference allows programs on the Solana blockchain to be more efficient and faster because they do not have to process the data of the program in addition to the code.

Solana's Rent System

Because of the unique structure of Solana storing data into unique accounts, there is a fee associated with all the account created, which is not seen in EVM.

Solana rent is a time-and-space based fee that validators on the network need to maintain a working copy of account state in memory. This rent is charged for the use of this resource consumption. Accounts which maintain a minimum balance equivalent to 2 years of rent payments are exempt from paying rent. The 2 years is drawn from the fact that hardware cost drops by 50% in price every 2 years and the resulting convergence due to being a geometric series.

Accounts whose balance falls below this threshold are charged rent at a rate specified in genesis, in Lamport per byte-year. The network charges rent on a per-epoch basis, in credit for the next epoch, and Account::rent_epoch keeps track of the next time rent should be collected from the account.

Decodable v.s Not-decodeable

It is easier to decompile contracts on the EVM, as there are various online tools that can do this. This makes it easier to understand the content and behavior of deployed contracts. One key difference between Solana and EVM is that Solana does not use a traditional virtual machine, which makes it difficult to decompile code. This makes it more difficult for someone to copy and paste a chunk of code and re-brand it as their own program.

Differences in the Application Layer:

The EVM-based smart contracts cannot be updated natively because they are executed in a virtual machine which is immutable. Any change to the code will result in a new contract address and execution of the new code.

Separating the code from data makes it easy to upgrade programs.pdates in Solana are much easier because there is no need to redeploy the entire program when upgrading. Instead, a new version of the program can be deployed to the same address while reusing the same data account. This upgrade process is much more efficient and minimizes any potential loss of data.

One advantage of the System Program is that it helps to ensure the security of the data within accounts. The System Program is a native program on Solana that is responsible for creating accounts, allocating data on accounts, and assigning ownership of accounts to the connected programs. This means that it is trusted by all validators on Solana and can be relied upon to handle transfers of tokens securely. Additionally, because the System Program is required to be run by all validator, it helps to ensure consistency across the network.

In this workshop, we also went through two code repos to demonstrate the differences stated above, which can be found here:

Mirror World SDK

Mirror World SDK is a set of cross-platform tools aiming to help developers integrate blockchain more efficiently, easily and cost-effectively.

Blockchain Software Development Kit, or as we all refer to Blockchain SDK or crypto SDK, is a set of software tools and programs used to help to create apps on blockchain platforms. A well-built crypto SDK streamlines the process of developing blockchain functionalities and brings a wide array of benefits.

Even though an SDK could seem simple in terms of lines of code, it profoundly impacts a product's adoption and maintenance, making the onboarding process more accessible for all. While Mirror World is developing its crypto mobile SDK, learning more about the common pain points, as well as constructive feedback, considering SDKs on the market could contribute to the development of general guidelines.

With that, this research will address the following questions that are constantly brought up in discussion amongst developers:

1. What makes a good SDK?

2. How to upgrade the SDK?

3. What are the key factors for developers to consider when selecting an SDK?

I. What makes a good SDK and how to make one?

An ideal SDK should include:

1. A comprehensive collection of tools, with independent modules, that enable software developers to build applications faster.

2. Excellent extensibility and expandable properties.

3. Low-cost learning, providing thorough documentation and frequent updates on samples and questions.

4. Full supporting services, including tutorials, demos, bug reports, and a developer community.

5. Error handling through better reports on bug fixes.

6. Clear versioning.

Low Code

Write less code: the more interfaces, the more code, and the greater the possibility of having bugs. Nowadays, as the size of a mobile app directly determines whether users download it, it is crucial to ensure that an SDK is lightweight, allowing developers to access it quickly and easily.

To create secure wallets, mint NFT, deploy marketplaces, and swap tokens with a few lines of code, you can easily authenticate your users through Mirror World SDK without the hassle of making users manage seed phrases, or present them with various popups to perform simple actions on Solana.

That being said, how to build a lightweight SDK of your own? A few guidelines below can help facilitate the development process.

1.Synchronous Call

Encapsulate complex functions and provide a unified entry for external uses. Try to shield implementation details, reducing the effort of understanding parameters.

For example, with Mirror World mobile SDK, user login can be accomplished with a simple function call:

More examples can be found at: https://docs.mirrorworld.fun/

2. Centralized Configuration

Use one file to configure complex parameters, rather than adding them everywhere. If the developer wants to change certain parameters, there is no need to write additional code, which makes it easier to maintain projects and support multiple environments.

3.Loose Coupling

Have clear boundaries and reduce the interdependencies across modules. The team should communicate and decide on the functionality each module implements.

In cases when developers only need a single service, it is important whether each module can be built, tested, and debugged individually. To deploy a marketplace for your application, for example, Mirror World SDK provides the most powerful decentralized marketplace architecture on Web3, allowing users to click, buy, and transfer NFTs with one click.

Clarity

When developers choose an SDK, they tend to judge based on the documentation preview. Since adopting a new SDK has its learning cost, the documentation has to be concise and self-explained to stand out.

Here are a few strategies to increase clarity:

1.Structured Table of Contents

Categorize code by function and put it under the specified directory. Consider standard practices such as subcontracting, layering, etc., so that users can know the role of each at a glance.

2.Formatted Code

Have a single, shared style and enforce it through automatic formattings, such as the use of 4 spaces. Though it is hard to implement throughout the actual development process, code formatting is necessary for a team to understand a project better and maintain it.

3.Naming

Use consistent naming for functions of SDK, try to make it align with user habits, and be self-explanatory without reading the documentation.

4.Annotation

Add comments before each directory and function, making sure that developers can know what it does and how to use it at once.

Extensibility

A major difficulty in creating an SDK is to balance the most usage scenarios and the customized needs of a small group of users. Its extensibility is thus important for iterations, or else any change implemented will affect the whole framework.

In that regard, Mirror World SDK is built from the ground up to be modular, so developers can choose which services they need. The incremental adoption also allows users to implement Token Sampras or simple application login.

Here are several ways to improve extensibility:

1.Dependency-Less

Minimize the dependencies of the SDK on other libraries. Less dependencies can reduce both its size and, more importantly, the likelihood of confronting conflicts.

In case developers want to add some functions, the integrated third-party library should be deployed and utilized as a plugin, isolated for easy access. When a problem occurs, such as high CPU usage or memory leaks that are difficult to troubleshoot, developers can quickly narrow the recurrence path, locate the problem, and remove the specific third-party library.

2.Third-Party Libraries

If the SDK uses a third-party library, it should define some interfaces and then share them directly with developers for review. If developers strongly desire to replace third-party libraries, they should be permitted to do so.

3.Customization

In addition to built-in functionality, it is recommended to provide a standard interface for developers to override the default and fill in their own implementations for components, which improves flexibility to a large extent.

Stability

Following the rapid increase in SDK developers, more inexplicable bugs have been found. With less dependencies, their impact on users is hard to measure, which is why ensuring the stability of SDK is vital.

Below are several ways to increase stability:

1.Testing

Unit tests (UT) are aimed at testing small isolated components of code, ensuring that each function is working properly. Additionally, developers can estimate the execution efficiency of SDK through load testing.

Adding this information to the documentation is recommended, and the team can optimize its performance afterward.

2.Changelog

Semantic versioning is important as developers often complain about frequent updates breaking backward compatibility.

Minimize changes to core functions and interfaces, especially the names, input parameters, and return values. For relatively significant changes, developers can guide users by writing a new function and annotating it along with the previous one.

Developers can also decide on the version number and solely change the minor version number for small changes. Such design can give others the expectation that this is a large-scale change and may exist in incompatibilities.

Mirror World SDK keeps its changelog updated through Github.

3.Exception Handling

Make sure that developers are aware of the exceptions and deal with them accordingly to prevent unexpected errors.

4.Complete Log

The key function calls must have a log, showing complete calling path while locating and debugging a problem that is not easy to reproduce.、

5.Monitoring

Quantifying problems such as memory, CPU usage, and frame rate.

6.Customer Service

The efficiency with which the SDK team provides services is important. It has to ensure effective bug reporting and fast bug fixes on a daily basis.

II. Factors for Developers to Consider

When deciding between multiple SDKs, what factors will developers consider? Spending time and effort on building these aspects helps drive widespread adoption.

Documentation

Documentation directly impacts usage, as it decreases the amount of time spent onboarding new users while acting as the sales book. An SDK without documentation is often out of consideration.

Ergo, a team must create clear and complete documentation introducing ways to import SDK, services provided, and how to use them. Other details, including frequently asked questions, can be added as well.

Tutorial & Demo

A useful SDK is often equipped with step-by-step tutorials. If not, at least code samples of runnable programs are necessary.

It is recommened to provide existing templates and common integration methods as a reference, allowing developers to create their own software quickly.

Start by selecting a development device and configuring the development environment, then use the IDE (Integrated Development Environment) to create an empty project, integrate the SDK, implement basic logic, build and run the project, and test the result.

With that being said, getting started with Mirror World SDK in your application requires only 3 simple steps:

1. Create a developer account on the Mirror World Developer Dashboard

2. Create a new project. Copy the API Key and clientId.

3. Install the SDK in your project and start using it.

Community

Having a support community with group chat, forum, and customer services is also important.

Mirror World SDK has already established various systems in place to support developers through the process. The main avenues are Discord, Telegram, Support tickets, used to address questions, post announcements, seek collaboration on projects, and chat with the maintainers. The team hopes to provide a valuable knowledge base and support system for all blockchain developers, even beyond Mirror World Mobile SDK users.

Funtionality

Developers prefer an all-in-one solution instead of multiple engines that do few things for developers. Each SDK has its learning cost, and having more may cause compatibility problems.

Different types of crypto wallets available on the market today support different functionalities. However, one major issue with these wallets is their level of complexity that more often than not pushes people away. Mirror World SDK aims to fill this gap.

When it was launched in 2017 by its founder, Solana aimed to solve three major problems faced by blockchain developers: decentralization, security, and scalability.

However, in the wake of its operations, Solana has amassed a market capitalization of at least fourteen billion and is ranked ninth in the crypto industry. However, the complex nature of web 3 and blockchain technology has failed numerous users.

Modern crypto wallets require one to be conversant with coding and app development to access some of its features. In addition, most blockchain wallet services are very expensive for small-scale investors to eek a living. It is more cumbersome for gamers to use crypto tokens and NFTs to perform in-game purchases as it involves leaving a game completely to facilitate transactions. Among many other features, this has reduced its operability and applicability to numerous admirers of cryptocurrencies. Mirror World aims to offer innovative solutions through its services in various ways.

What Are Crypto Wallets

Since 2009, over twelve thousand cryptocurrencies in the market have been launched and are being used to facilitate various transactions around the world. These currencies offer some advantages over fiat currency, such as eliminating the need for a trusted third party to oversee transactions. In addition, traditional transactions are cumbersome and slow and are prone to manipulation and corruption by the central authorities.

Cryptocurrencies overcome this problem through the use of blockchain technology which is not only fast but also reliable. To use blockchain technology, one needs to have a blockchain wallet. A blockchain wallet is a type of cryptocurrency wallet that lets users handle a variety of cryptocurrencies, including Bitcoin, Solana, and Ethereum. A blockchain wallet makes money transfers simple, because they are cryptographically signed, transactions are safe. The wallet can be accessed from web-enabled devices, including mobile ones, and the user's identity and privacy are upheld.

The procedure is similar to sending or receiving money using PayPal or any other currency payment channel, except that you use cryptocurrency. Electrum, Blockchain.info, Jaxx, Mycelium, Samurai, Phantom wallet, Mirror world, and Bitcoin paper wallets are a few examples of blockchain wallets. There are many more options depending on your demands and the level of security you demand.

How Crypto Wallets Work

Blockchain wallets operate through the use of public and private keys that are generated once a user creates a blockchain wallet. These keys are important as they serve to identify and secure your account. The public key is used to identify a specific user and is similar to an email address or a username on a social media site. It is unique to each user, and its main purpose is to identify and differentiate each user. On the other hand, private keys lock and keep an account secure from other users. This is akin to passwords that are used to lock the accessibility of different accounts. It is unique to each user and is meant to ensure that funds in a blockchain wallet are secure. Third parties having access to your private key implies that an account has been compromised, and one can lose their funds. Some of the advantages of crypto wallets are as follows:

• They are easy to use like normal day-to-day wallets.

• They are highly secure through the use of public and private keys, which are generated when a user creates an account.

• Unlike other banks and conventional wallets, these wallets have low transaction costs.

• These wallets are free from national and border barriers allowing instant transactions across different geographies and countries.

• These wallets can store multiple forms of cryptocurrencies.

Types Of Crypto Wallets

Hot and cold wallets are the two categories of private key-based blockchain wallets. Hot wallets resemble the everyday wallets we use for daily transactions and are simple. Cryptocurrencies are securely stored in cold wallets akin to a vault. Hot wallets are online wallets that allow for rapid cryptocurrency transfers. They can be found online. Examples include Blockchain.info, Phantom, and Coinbase.

Digital offline wallets, known as "cold wallets," sign transactions offline before disclosing them online. They are maintained offline rather than in the cloud on the Internet to preserve strong security. Trezor and Ledger are two types of cold wallets currently available. Private keys are kept in the cloud regarding hot wallets to facilitate quicker transfers. In cold wallets, private keys are kept on a paper document or in separate hardware that is not linked to the Internet or the cloud. Hot wallets are accessible 24/7 on a desktop or mobile device, but if they are hacked, there is a risk of irrecoverable theft. With cold wallets, the manner of the transaction aids in preventing illegal access to the wallet (hacking and other online vulnerabilities).

These wallets can further be categorized into soft, hardware, and paper-based wallets. A software wallet is an application downloaded onto a computer, a mobile device, or a web-based wallet that can be accessed online. Additional classifications include desktop wallets, web wallets, and mobile wallets. Desktop wallets are "cold wallets," meaning they store their users' private keys on remote servers (on your desktop). On the Internet, there are various other hot wallet types. These wallets are accessible to users on any device. You can access it from your mobile browser, tablet, desktop, or another device. Online and mobile wallets are comparable. However, mobile wallets are designed exclusively for mobile phone use and accessibility.

How Solana Works With Mobile Wallets

Solana labs launched Solana Mobile stack, An open-source Android software toolkit enables native Android web3 apps on Solana with the Seed Vault safe custody protocol, providing rapid transaction signing while keeping private keys separate from wallets, apps, and the Android operating system. The Solana Mobile Stack (SMS), designed to work with Android, offers a new set of libraries for wallets and apps that enable developers to build rich mobile experiences on Solana, the fastest blockchain in the world. The SDK makes it easier for developers to create and add to the functionality of dApps for Solana by providing libraries and programming interfaces for Android apps and secure key private storage. However, this is a more complicated approach to user authentication as it is a rigorous process that requires installing several programs and software. Moreover, it requires one to be proficient in coding in blockchain; thus, finding an alternative authentication mode would present a better alternative.

All In One Login With Mirror World Mobile SDK

For developing mobile and web applications into Web 3 Architecture, the Mirror World Mobile SDK is a cross-platform toolkit that offers straightforward, declarative APIs and SDKs to access various blockchain features. Traditional Web3 Solana development is difficult to use on mobile devices. Users and developers must thoroughly understand complicated terms like key pairs, wallets, seed phrases, private key security, and transaction signing.

Mirror World aims to offer top-notch open-source SDKs for Android, iOS, Unity, and Web that take the complexity out of authentication, NFT Marketplace Trading, tokenization, on-ramps, and off-ramps for users in response to the growing global usage of mobile in Web3. Mirror World's SDKs and APIs support several platforms that enable web building and are currently supporting Solana. Future developments are aimed at market leaders like Ethereum, Polygon, BNB chain, and Aptos. Users can easily authenticate themselves for native Web3 applications with Mirror World's seamless user authentication. The authentication process utilized by Mirror World is a practical strategy that is both accessible and well-liked. Using services like Google, Apple, Twitter, Discord, and email and password authentication permit social authentication procedures.

Security of wallets powers by Mirror World SDK is ensured via MPC. MPC is a cryptographic technology that allows for secure collaboration between multiple parties. This is done by having each party submit a portion of the computation, and then combining all of the results to get the final answer. This makes it difficult for any one party to gain control of the system, as they would need to control all of the individual parts. This makes MPC a great choice for security-sensitive applications, such as asset management.

Conclusion

Web3 holds numerous potential as it offers a peer-to-peer connection between computers and users. However, it is faced with cross-platform operability and a lack of the required know-how to use its advanced features. Mirror World SDK solves this problem by creating a platform that is easy to use. It uses a one-step login process utilizing popular authentication services like email addresses and passwords using Google and Apple login services. Finally, with the use of cryptocurrency such as Solana, it aims to overcome transaction barriers such as geographical and international barriers moreover overcome issues such as slow transactions, high transaction costs, and manipulation of receipts.

What is a crypto wallet?

A crypto wallet is an app that transfers digital transactions or cryptocurrencies between participants in a particular blockchain network and triggers intelligent contracts on the blockchain. Its storage function is the same as an electronic wallet, but it applies to cryptocurrencies. It is part of the software that securely stores cryptocurrencies and tracks their transaction records (purchases, sales, credit). The wallet also plays the role of an identifier and a blockchain account.

Cryptocurrency wallets can be used as quickly as possible by installing them on smartphones. Laptop or any browser, or, It can also be stored in your pocket.

Crypto wallet types

There are two classes of crypto wallets, hot and cold. The significant disparity between hot and cold wallets is the internet connection.

Cold crypto wallets are generally hardware wallets. Public and secret keys are reserved offline on devices that are not connected to the Internet. Many of the popular tricky crypto wallets look like ordinary flash drives. Security-conscious people prefer cold wallets because they are not connected to the Internet, making them the most secure against cyber-attacks. However, cold wallets can be physically lost, stolen, or left behind.

On the other hand, hot wallets are based on high-tech software, not hardware. Hot wallets can be installed or managed on the Internet. There are three kinds of hot wallets: web, desktop, and mobile. Web wallets are most convenient because they are accessible from any device with an internet connection. It also relies on the cloud.

1. Desktop wallet

Desktop wallets are intended for use on desktop computers and laptops. You can access it from the initially installed computer. Desktop wallets are believed secure unless your computer is contaminated with a virus.

2. Mobile wallet

Mobile wallets usually have the same features as desktop wallets. However, touch-to-pay and NFC (Near Field Communication) allow users to scan the QR code and make payments in physical stores easier. Bitcoin wallets and Hive Android are examples of mobile wallets.

3. Web wallet

A web wallet makes it easy to access crypto from anywhere, such as a browser or mobile device. Web wallets work in the cloud. The secret key is stored online and is very convenient.

However, it is vulnerable to hacking attacks because third parties indirectly control it.

Method For Developing Crypto Wallet

Once you've defined that you need to develop a crypto wallet and decided what kind of future app you like to complete, you can concentrate on devising a cryptocurrency wallet. Below we outline the most critical steps in the development of crypto wallets.

Learn about cryptography

You need to understand the technology before you start coding. At this phase, you will require to decide what features you like to have in your wallet, what technology stack you wish to use, and what kind of wallet you need for your coins.

Use libraries to build wallet

You can use some libraries to develop your wallet. For example, Mirror World Software Development Kit (SDK) provides all-in-one solutions that allow you to create wallets for Unity, iOS, and Android platforms.

Select the appropriate technology stack

The right technology stack will bring the success your app needs. For example, when building a web app, you can use Node.js or Angular.js in addition to HTML5 and CSS3. It allows you to create scalable encrypted web applications. When making a native Android app, you can choose between Java or Kotlin. Also, for iOS apps, you can use Swift or Objective-C.

Use API and appropriate cloud platform

Implementing an Application Programming Interface (API) is a great way to build crypto wallets that support multiple currencies. It will be easy to synchronize with any blockchain network. The API can accelerate the development process. Another helpful piece of suggestion for setting up a cryptocurrency wallet is discovering the right cloud platform. In this case, you should consider a BaaS (Blockchain-as-a-service) provider. Amazon, Azure, Microsoft, and others provide this service.

Check out competitors

You like your crypto wallet app to stand out in public. So, it's vital to keep an eye on your competitors. You can see what competitors are doing and what technologies they are including. Check out what unique features you can add to your app. Remember that to be competitive with others; you need to know what's happening around you.

Ensure app security

The security of crypto wallets is a significant consideration in the app development process. Learning how to protect your wallet and your client's cryptos would be best. In addition, you can add special protection like biometric authentication to open the app with the help of the face, retina, and fingerprints. You also need to check if your app has two-factor authentication, take a backup of your wallet, and provide continuous security updates.

Start developing an app.

When you're all set to start developing your crypto wallet app, make sure you:

• Determine the full functionality of the app.

• Determine the full functionality of the app. Write the application code and integrate it with the database.

• Design a simple and user-friendly interface.

• Make sure to do extensive testing before releasing your wallet.

Key Features to Include in Crypto Wallet App

• Authentication (which is an integral part of most applications and a reliability issue in financial applications)

• Session duration (essential for security, any financial app)

• QR Code Scanner (Automated Wallet Address and Public Key Scanning increases the speed, convenience, simplicity, and security of transactions within the app)

• Multi-Currency (If your application does not target specific crypto, adding an option that works in multiple currencies, including Fiat, can significantly expand the targeted user).

• Integrity (Another advantage of the app is that it imports a mobile wallet into a more secure paper wallet with the same QR code)

• Push notifications (messages that notify users of transaction status, exchange rate changes, conversion rate changes, and so on).

• Fees (Crypto wallet app should always be able to calculate variable prices)

• Blockchain (All completed transactions are transferred to the blockchain network and stored there)

Final Words

Like other financial products, crypto wallets are a complex technology that requires the utmost involvement of experienced professionals such as developers, testers, business analysts, and marketers.

The gaming industry is experiencing a renewed renaissance. 

In recent years, Covid-driven social isolation saw the industry experience a surge of new users and profit. According to Mordor Intelligence, the gaming industry was valued at $198 billion in 2021, and is expected to reach $339 billion by 2027. 

Accenture also noted that 84% of survey respondents said gaming helped them connect with people with similar interests. 

Besides the social experience, the integration of new technologies, especially blockchain is helping fuel growth and attract a new segment of gamers interested in financial gain. 

In recent years, blockchain gaming has become so popular that the niche industry grew by 2,000% in the one-year period from 2021 to 2022.

To understand what blockchain gaming is, let’s first look at blockchain technology itself.

As a decentralized and shared database, the blockchain acts as a ledger that verifies and maintains a record of cryptocurrency transactions such as Bitcoin and Ethereum. Besides digital currencies, the blockchain performs the same task for non-fungible tokens (NFTs) or digital assets.

So how does the blockchain fit into games?

Unlike traditional online games, blockchain games are not hosted on a centralized server that only the creator has access to. The blockchain decentralizes gaming, with the community responsible for development and outcomes. 

If the game creator decides to push an unpopular update, players can fork or take the game’s source code and build a different version.

Blockchain games also allow players to use cryptocurrency to buy, trade, and sell in-game assets or experiences on a marketplace.

To play, users must own cryptocurrency in a digital wallet. The most common cryptocurrency used in crypto games is Ethereum as most games are built on the Ethereum platform.

How Can Blockchain Be Used In Gaming?

The main benefit of blockchain integration in gaming is the ability it gives players to have true ownership over their characters, features and in-game assets.

This is because the blockchain helps authenticate ownership and prevent duplication of items.

Before blockchain games, in-game assets or accrued experience such as extra lives, special weapons, and virtual currency could only be used in that game. Once the player stopped playing, the assets became worthless and had no value elsewhere. 

This centralized model benefited game developers over players and users. 

With the decentralized blockchain, players have more control and can transfer their assets anywhere on the network, including to other games.

How Blockchain-Based Games Earn Money

Blockchain games provide creators a variety of ways to earn money. 

In the first method, creators make a game free to play in the hope of maximizing reach and to build an active community of players.

As players engage and trade or sell game items in the marketplace, the creators receive a share of the transaction fee or gas fee levied on each exchange of items linked to their game. 

The gas fee is a small tax applied on each transaction on the blockchain to compensate individuals who devote computing power to verify transactions. This also helps prevent the system from being overwhelmed. 

Some crypto game developers also partner with advertisers to display in-game ads which players are forced to watch in exchange for an award, but this format is not common as it’s unpopular amongst gamers.  

Instead, partnerships are taking a creative twist. For example, crypto game developer Spinterlands recently partnered with Warner Bros to make games in which artists under their label can promote their music and build a brand.

The other source of income available to creators is to charge an entry fee or force players to purchase items to gain access.  

Some developers take this a step further by requiring additional purchases to improve the gaming experience.

Why Are Blockchain Games Popular?

Blockchain games are entertaining and integrate real-world economics into the gameplay.

By allowing players to make money while having fun, their meteoric rise in popularity becomes easy to understand.

But monetary gain is not the sole reason for the success of crypto games.  

There are a range of reasons under the hood. One of these is that blockchain-based games eliminate inefficient third-party intermediaries during in-game transactions. 

This means that money can be moved fast, and without any hidden fees which allows players to maximize profit.  

Players also find it easier to stay anonymous in crypto games as there is no requirement to share their personal information such as name or email. 

Blockchain games are also secure. 

Over the years, most major gaming platforms from Steam to xBox Live and Sony Playstation have been hacked, with confidential information of players from logins, passwords, and credit card details leaked. 

Play-to-Earn Games Explained

Games based on the play-to-earn (P2E) model let players earn rewards with real-world value through some necessary interaction. 

Examples of such interactions include completing tasks, beating other players in battle, or leveling up in the game. These rewards take various forms, ranging from NFTs, crypto tokens, virtual assets, or special game features. 

These rewards can then be exchanged or sold on a marketplace for fiat wealth. 

Although blockchain games are still in their nascency, the P2E model has taken the world by storm and has the potential to redefine the gaming experience altogether. 

In the Global South, P2E is helping improve lives by providing alternative career options. For example, in the Philippines, it’s not uncommon for crypto gamers to earn double or triple the minimum wage. 

The same pattern has emerged in other developing markets such as South America.

For example, Argentines are leading the region as crypto gamers to beat inflation.

With a growing user base in developing countries, the P2E model can be life-changing. 

Examples of Blockchain Games

With over 400 blockchain games, getting started can feel overwhelming. 

While some gaming studios follow a formula, others innovate and set trends. 

An example of the latter can be seen in Mirror World blockchain games. Mirror World is a gaming matrix featuring AI-powered virtual beings known as the Mirror. 

These entities or mirrors fight along players in the game universe.

Mirrama  

Mirrama by Mirror World is an action role-playing crypto game available on iOS and Android. 

Set in the city of Xalem riddled with plague and monsters, players must use their skill to find a way out.  

Mirrama characters are classified by their rarity, level, class, and faction. These factors play a key role in subsequent growth and development 

Brawl of Mirrors

As a player-verus-player game, Brawl of Mirrors is all about strategy and beating opponents. 

Like Mirrama, characters in Brawl of Mirrors are classified by various attributes that influence health points, attack and defense power, and stamina.

The game is still in the testing phase but will be available for iOS and Android. 

Axie Infinity

Built by Vietnamese gaming studio Sky Mavis, players in Axie Infinity raise digital pets known as Axies.

To get started, each player must purchase three Axies. From here, the virtual creatures can be raised for collection, breeding, or battle. 

With almost 709,000 active players in the last month, it’s one of the most popular blockchain games in the market today.   

The Sandbox

Built by Pixowl, The Sandbox is a virtual world or metaverse multiplayer game built on the Ethereum blockchain. 

Using the game’s token, known as SAND, players can purchase, build, and govern digital real estate in the form of an NFT. 

Within their property, players can customize the area with playable games and experiences. 

Besides the average gamer, celebrities are also jumping into The Sandbox. Recently, it was revealed how Snoop Dogg had built a private mansion in the game to host exclusive parties and present his NFT collection.

Not far behind are big corporations such as financial services provider HSBC who bought land to engage with esports and gaming enthusiasts. 

Splinterlands

Splinterlands is an NFT card game, much like Magic: The Gathering.

Created by Jesse Reich and Matt Rosen in 2018, and running on the Hive blockchain, the basis of the game is to get players to battle through cards.

Winners of a battle are awarded dark energy crystals, an in-game token, which can be exchanged for other cryptocurrencies or cash. 

Besides battle, players can also go on quests to earn tokens and get access to special potions and booster packs. 

With over 500 cards in the game based on seven elements or Splinters: fire, water, earth, life, death, dragon, and neutral, the game had 363,000 active users in the last month. 

Alien Worlds

Alien Worlds is a space exploration game which lets players explore and scavenge planets for resources, earn in-game tokens, and complete missions to earn unique items. 

Developed by Sarojini McKenna and Michael Yeates, the game runs on multiple blockchains, including Ethereum, WAX, and Binance Smart Chain. 

Alien Worlds is among the most popular crypto games, with over 700,000 monthly active users and 11 million daily transactions. 

The Future of Crypto Gaming

Despite the volatility of the cryptocurrency market, blockchain-based games continue to attract investment. 

In just the first quarter of this year, 128 crypto gaming companies racked up a total of $1.2 billion in funding, according to a report by Drake Star Partners. 

Both individuals investors and venture capital firms are pouring money in. A few examples include Mark Cuban backing Sky Mavis with $7.5 million and Framework Ventures launching a $400 million fund for Web3 startups, including games. 

Besides investors, blockchain platforms such as Solana and Polygon are also investing in crypto games. 

Solana is investing $150 million into crypto games being built on the Solana blockchain while Polygon is spending $200 million to do the same for games on its network. 

Further helping push crypto games into the mainstream are traditional studios such as Epic Games who revealed it was open to adopting blockchain games .

But it’s not all good news. Last year, Steam, a leading gaming platform, similar to Epic Games, decided to block blockchain games on its platform and reiterated its policy to ban items that have real-world value. 

Despite the setback, a constant stream of investments, hype, and positive use case means the future is bright for crypto games. 

How to Invest in Blockchain Gaming

Whether you’re a gamer, have never played a game before, a blockchain enthusiast, or looking to diversify your portfolio, the good news is anyone can invest in crypto games.

One of the easiest ways to get started is to purchase game tokens directly on an exchange. 

For example, AXS, which is used in Axies Infinity can be purchased directly on Binance. 

Another option is to directly invest in crypto gaming studios during funding rounds. 

For example, Sky Mavis and Enjin both recently raised capital. Investing at the source rather than a volatile token market can be a better alternative for more risk-averse investors. 

But outside of these options, the best method to invest in crypto games is to spend time playing a game and earning rewards.

Key Takeaways

Blockchain technology is disrupting entire industries, including the gaming market. 

Early crypto games have laid the foundation for widespread adoption and have merged the worlds of entertainment and finance.

Here are the facts everyone should know about crypto gaming: 

• Crypto games provide a decentralized experience which gives players full ownership over characters and assets rather than a single centralized entity 

• Players can earn real money while playing with the play-to-earn model 

• The crypto gaming market is booming in developing countries where players can often earn more their normal wage

• Alien Worlds and Axie Infinity are two of the most popular crypto games

• Despite the challenges and volatility of crypto markets, investors are betting big on crypto games and and investing in new projects
