What is a Decentralized Application (dApp)?
A decentralized application (DApp) is an application built on the basis of a decentralized network and consisting of a smart contract backend and a user interface frontend.
DApps are “non-permissive”, meaning anyone is free to use them. Indeed, many DApps include smart contracts written by others. They are also transparent and “untrustworthy”, meaning anyone can verify their authenticity and functionality.
Understanding Decentralized Applications (dApps)
Web applications such as Uber or Twitter run on the basis of a computer system that is owned and operated by a company that has the authority to manage the application and its operation. Regardless of the number of users, the backend is controlled by the company.
DApps can work on a P2P network or on a blockchain network. For example, BitTorrent, Tor, and Popcorn Time are applications running on computers that are part of a P2P network that allows multiple participants to consume content, transmit it, or sow it.
DApps applications run on the blockchain network in a public, decentralized, open source environment and are free from control and interference from any one authority.
For example, a developer can create a Twitter-like dap and place it on a blockchain where any user can post messages. After publication, no one, not even the creators of the application, will be able to delete these messages.
DApp Uses
DApps applications have been developed to decentralize a number of functions and applications and eliminate intermediaries. Examples include self-executing financial contracts, multiplayer games, and social media platforms.
dApps applications have also been developed to provide secure voting and blockchain-based management. dApps can even be integrated into web browsers as plugins that allow you to place ads, track user behavior or collect cryptocurrency donations.
Some examples of practical use of dApps include
Financial Services
dApps can be used to simplify peer-to-peer financial transactions such as currency exchange or asset transfers.
Supply Chain Management
dApps can be used to track the movement of goods along the supply chain, ensuring transparency and accountability.
Identity Verification
dApps can be used to securely store and verify identification information, for example, for voter lists or passport applications.
Real Estate
dApps can be used to facilitate the purchase and sale of real estate directly between the buyer and seller, as well as to track the ownership of real estate and related documentation, such as documents.
Healthcare
dApps can be used to store and track medical records, as well as to facilitate communication and interaction of healthcare professionals.
Education
dApps can be used to create decentralized learning platforms that allow students and teachers to interact and collaborate directly, without intermediaries.
Social Networks
dApps can be used to create decentralized social media platforms that allow users to interact and share content without the involvement of a central authority.
Prediction Markets
dApps can be used to create decentralized platforms for prediction markets, allowing users to make predictions on various topics and potentially receive rewards for accurate predictions.
DApp Scams
Fraudulent actions are committed through dApp. There are known Ponzi schemes in which early investors receive money at the expense of investments by later investors, creating the appearance of large profits.
Fake initial coin offerings (ICOs) were used to raise funds for the development of a new cryptocurrency or dApp, which were not going to be created.
Phishing attacks have been noticed on dApp, when people were deceived using fake websites or emails to force them to disclose confidential information.
In addition, some dApps are used to distribute malware or viruses that can compromise users’ devices and steal confidential information.
It is important for users to exercise caution and due diligence when interacting with dApps, as the decentralized nature of these applications can make it difficult to track and hold attackers accountable.
According to the industry analysis group DappRadar, in 2022, a record number of hacks and vulnerabilities were recorded in dApps – 312, which led to losses of about $ 48 billion.
Advantages and Disadvantages of dApps
Advantages
Many advantages of dApps are related to the fact that the program ensures the privacy of users. In decentralized applications, users do not need to provide their personal information to take advantage of the function that the application provides.
DApps use smart contracts to complete a transaction between two anonymous parties without having to rely on a central authority.
Freedom of speech advocates point out that dApps can be developed as alternative social media platforms.
The decentralized social media platform is resistant to censorship, since no blockchain participant can delete or block messages.
Ethereum is a flexible platform for creating new dApps, providing the infrastructure necessary for developers to focus their efforts on finding innovative ways to use digital applications.
This can allow the rapid implementation of dApps in various industries, including banking and finance, games, social networks and online stores.
Disadvantages
The use of dApps is still in the early stages, which means it is experimental and involves certain problems and unknowns. There are questions about whether applications can scale effectively. There are concerns that an application requiring significant calculations will overload the network, causing it to overload.
Another problem is the possibility of developing a user-friendly interface. Most users of applications developed by traditional centralized institutions expect ease of use, which encourages them to work with the application and interact with it.
In order to get people to switch to dApps, developers will need to create an interface and a level of performance for the end user that is not inferior to popular and already existing programs.
Another limitation of dApps is the difficulty of making changes to the code. After deployment, the DApp is likely to need constant changes to make improvements, fix bugs or security risks.
According to Ethereum, it may be difficult for developers to make the necessary updates to the DApp, since the data and code published in the blockchain are difficult to modify.

What is SKALE token (SKL)
SKALE token (SKL)
Decentralized applications (dApps) can benefit from the high-performance, adaptable, and modular blockchain infrastructure offered by the decentralized Ethereum-compatible SKALE Network.
The SKALE Network’s goal is to improve user experience for users while assisting developers in building and scaling dApps.
The native cryptocurrency of the SKALE Network is the SKALE token (SKL). It is employed to reward network users, such as validators, delegators, and developers.
Validators are in charge of examining network transactions, and they are compensated with SKL tokens for their efforts. On the other hand, delegation allows users to share in the rewards by transferring their SKL tokens to validators.
The SKALE token is essential to motivating and supporting the SKALE Network, which intends to become a top platform for the creation and implementation of decentralized applications.
The history of SKALE (SKL)
As the native cryptocurrency of the decentralized, Ethereum-compatible SKALE Network, which was created to provide high-performance infrastructure for decentralized applications (dApps), the SKALE token (SKL) was introduced in 2019.
Early in 2019, during the public auction, the SKL token was introduced. Three phases of the sale were held, the first two of which were open to authorized investors and the third of which was offered to the general public.
As a component of the Phase 2 mainnet launch, which was finished and declared by the SKALE Network in December 2020, the Elastic Sidechains of the SKALE Network were merged with the Ethereum mainnet. By using this interface, dApps can benefit from the speed and scalability of the SKALE Network while still preserving the security and compatibility of the Ethereum mainnet.
Overall, the SKL token has been crucial in motivating and sustaining the growth of the SKALE Network, which intends to become a top platform for the creation and implementation of decentralized applications.
How SKALE (SKL) works
The SKALE token (SKL), which was developed to provide high-performance infrastructure for decentralized applications (dApps), is the native cryptocurrency of the decentralized, Ethereum-compatible SKALE Network.
Delegators can also delegate their SKL tokens to validators in order to share in the incentives. As a result, owners of smaller tokens can participate in the network’s consensus procedure and collect rewards without becoming validators themselves.
The SKALE Network also uses a new token economics strategy to maintain the SKL token’s strong demand. A portion of the SKL tokens used to pay for network resources are burned as part of this plan, reducing the total supply and raising the token’s worth.
In general, the SKL token is essential for spurring and supporting the expansion and growth of the SKALE Network. Additionally, it offers a variety of options for network users to participate in network governance and earn incentives.
Can SKALE (SKL) be trusted
Having said that, the SKALE Network and SKL token have been developed by a knowledgeable team of blockchain developers and business owners, and the network has received support from a number of well-known organizations and investors.
The network also uses a cutting-edge elastic sidechain architecture that provides developers full control over the speed and cost of transaction processing while also enabling their decentralized apps (dApps).
The SKALE Network has also been the subject of audits by a number of trustworthy third-party auditing firms, including CertiK and Trail of Bits, both of which have given the network positive recommendations for its security and usefulness.
Investing in cryptocurrencies is always risky due to factors like price volatility, regulatory uncertainty, and potential technical problems. People should consider these risks carefully and only invest money they can afford to lose.
How to get SKALE (SKL)
There are several ways to obtain SKALE tokens (SKL):
- Exchanges for cryptocurrencies: At the moment, SKL is listed on a number of significant exchanges, including Binance, Huobi Global, and Coinbase Pro. On these exchanges, users can exchange SKL tokens for fiat money or other cryptocurrencies.
- DEXs, or decentralized exchanges, allow users to trade cryptocurrencies without using a centralized exchange like Uniswap and SushiSwap. SKL is also accessible on both platforms.
- Staking: By staking their tokens on the SKALE Network, users can earn SKL tokens. For participating in the network’s consensus mechanism, validators and delegators are compensated with SKL tokens.
- The SKALE Network may occasionally give out SKL coins to owners of other cryptocurrencies like Ethereum.
It is important to note that buying and selling cryptocurrencies can be risky, and individuals should conduct their own research and due diligence before making any investment decisions.

DPoS allows for high transaction throughput and low latency, making EOSIO capable of processing thousands of transactions per second.
Accounts and Tokens: EOSIO uses an account-based model, where accounts are identified by human-readable names and hold tokens, which represent ownership of resources on the blockchain, such as CPU, RAM, and network bandwidth. Accounts can interact with smart contracts and send/receive tokens, and they can be controlled by private keys or other authorization mechanisms.
Resource Management: EOSIO employs a unique approach to resource management. Instead of requiring transaction fees, EOSIO allocates resources based on the amount of token ownership. This means that users do not need to pay transaction fees for every transaction, but rather stake tokens to gain access to resources. This is known as the Delegated Proof-of-Stake Resource Allocation Model (DPOS-RAM), and it aims to make EOSIO-based dApps more user-friendly and accessible.
Smart Contracts: EOSIO supports smart contracts, which are self-executing contracts with predefined logic encoded on the blockchain. Smart contracts on EOSIO can be written in multiple programming languages, such as C++, Rust, and WebAssembly (Wasm), and they can be updated without requiring a hard fork. EOSIO smart contracts are executed deterministically and can interact with other smart contracts and accounts on the blockchain.
Governance: EOSIO includes a system of on-chain governance that allows token holders to participate in decision-making through voting for block producers and proposing changes to the protocol. This aims to provide a decentralized and community-driven approach to the management of the blockchain network.
Developer Tools: EOSIO provides a suite of developer tools, libraries, and documentation to facilitate dApp development. This includes the EOSIO Software Development Kit (SDK), which provides APIs, smart contract development frameworks, and other resources to simplify the development process.
Account Recovery: EOSIO has a unique account recovery feature that allows users to recover their accounts if they lose their private keys or face other account-related issues. This is achieved through a designated account recovery process that involves trusted entities and multi-signature authorization.
Overall, EOSIO is designed to provide a scalable, flexible, and developer-friendly blockchain protocol for building decentralized applications and smart contracts. Its unique features, such as the DPoS consensus mechanism, resource management model, and on-chain governance, differentiate it from other blockchain platforms and make it suitable for various use cases in industries such as finance, gaming, supply chain management, and social media.

Does EOSIO charge a fee
EOSIO blockchain protocol does not charge transaction fees in the traditional sense. Instead of transaction fees, EOSIO uses a unique resource management model known as Delegated Proof-of-Stake Resource Allocation Model (DPOS-RAM).
In EOSIO, users need to acquire and stake EOS tokens to gain access to resources such as CPU, RAM, and network bandwidth. These resources are required to perform actions such as executing smart contracts, sending transactions, and storing data on the blockchain. The amount of resources required for each action depends on the complexity and computational requirements of the action.
When a user stakes their EOS tokens, they are essentially “renting” resources from the EOSIO network. Once the resources are used, they are returned to the network and can be reclaimed by other users. The staked EOS tokens are not charged or deducted from the user’s account, but they are temporarily locked and cannot be freely transferred or traded until the resources are unstaked.
This resource management model aims to eliminate transaction fees for end users and provides a more predictable and user-friendly experience for developers and users of EOSIO-based dApps. However, it’s worth noting that while there are no transaction fees in EOSIO, users still need to acquire and stake EOS tokens to gain access to resources, and the value of EOS tokens can fluctuate in the market. Additionally, some dApps built on EOSIO may implement their own fees or business models for their services, which are independent of the EOSIO protocol.
How to use EOSIO blockchain protocol

Dfinity decentralized cloud computing network
What is Dfinity
Dfinity is a decentralized cloud computing network and platform that aims to provide a secure and efficient infrastructure for hosting decentralized applications and services. It was founded in 2015 by Dominic Williams, and it has since raised over $166 million in funding from various investors.
Dfinity uses a unique consensus mechanism called “Threshold Relay” that allows it to achieve high levels of scalability, performance, and security. This consensus mechanism uses a decentralized network of nodes that work together to reach consensus on the state of the network.
Dfinity also supports a programming language called “Motoko” that makes it easy for developers to build decentralized applications and smart contracts. Developers can also use popular programming languages such as Rust and JavaScript to build applications on the Dfinity platform.
One of the goals of Dfinity is to provide a decentralized alternative to traditional cloud computing platforms such as Amazon Web Services and Microsoft Azure. By decentralizing cloud computing, Dfinity aims to create a more secure and democratic internet that is not controlled by a few large corporations.
The history of Dfinity
Dfinity was founded in 2015 by Dominic Williams, who was previously a software engineer at Microsoft and an early developer of the Bitcoin protocol. Williams started working on Dfinity after becoming disillusioned with the limitations of existing blockchain platforms, which he believed were too slow and expensive to support large-scale decentralized applications.
Dfinity’s early development was funded by a $3.9 million seed round led by Polychain Capital, and subsequent funding rounds raised over $166 million from investors including Andreessen Horowitz, Polychain Capital, and Placeholder Ventures.
In May 2018, Dfinity launched its “Genesis” network, which was a beta version of its decentralized cloud computing platform. This network was used to test and refine Dfinity’s consensus mechanism and other key features.
In 2019, Dfinity launched a public testnet called “Betasphere” to allow developers to test their applications on the Dfinity platform. Later that year, Dfinity announced that it had formed a partnership with the Ethereum Foundation to develop a “bridge” between the Ethereum and Dfinity networks, allowing developers to build applications that use both platforms.
In May 2021, Dfinity launched its mainnet, called “Internet Computer,” which enables developers to build and deploy decentralized applications on a global scale. The launch was accompanied by a $223 million token sale, making it one of the largest initial coin offerings (ICOs) in history.

How Dfinity works
Dfinity is a decentralized cloud computing platform that aims to provide a secure and efficient infrastructure for hosting decentralized applications and services. It uses a unique consensus mechanism called “Threshold Relay” to achieve high levels of scalability, performance, and security.
At a high level, Dfinity works by using a decentralized network of nodes to run applications and execute smart contracts. Each node in the network runs a copy of the Dfinity protocol, and these nodes work together to validate transactions and maintain the state of the network.
The Threshold Relay consensus mechanism used by Dfinity works by dividing the network into smaller groups of nodes called “committees.” Each committee is responsible for validating a specific subset of transactions, and they use a process called “random beacon” to determine which nodes are selected to participate in each committee.
Once a committee is formed, the nodes in that committee use a process called “threshold cryptography” to reach consensus on the state of the network. This process involves multiple nodes working together to validate transactions, and a certain threshold of nodes must agree on the state of the network before a transaction can be considered valid.
Dfinity also uses a “subnet” architecture to allow different applications and services to run on separate sub-networks within the larger Dfinity network. Each subnet is managed by a separate set of nodes, and they can communicate with each other to share data and execute transactions.
To make it easy for developers to build decentralized applications and smart contracts, Dfinity supports a programming language called “Motoko.” Developers can also use popular programming languages such as Rust and JavaScript to build applications on the Dfinity platform.
Overall, Dfinity’s unique consensus mechanism and subnet architecture allow it to achieve high levels of scalability, performance, and security, making it an attractive platform for hosting decentralized applications and services.
Is Dfinity safe
Dfinity aims to be a secure and decentralized platform for hosting decentralized applications and services. It uses a unique consensus mechanism called “Threshold Relay” that is designed to provide high levels of security and resilience against attacks.

Digital Asset Modelling Language (DAML)
What is Digital Asset Modelling Language (DAML)
The distributed ledger technology (DLT) platforms Hyperledger Fabric, Corda, and VMware Blockchain support the development of decentralized applications (dApps) using the programming language known as Digital Asset Modelling Language (DAML).
Developers can easily create secure and reliable smart contracts with the help of the declarative, type-safe, contract-oriented language known as DAML. It provides a high-level programming abstraction that streamlines the expression of intricate business logic and the development of intricate workflows. Moreover, DAML offers a strong data model that can manage intricate financial and legal instruments.
One of DAML’s important features is its support for multi-party workflows, which enables programmers to design smart contracts involving numerous parties that each have specific roles and responsibilities. Automation of intricate financial procedures is now conceivable, including supply chain management, insurance, and trade finance.
Because DAML is platform-agnostic, smart contracts created using it can operate without any changes on many DLT systems. This makes it simpler for developers to design dApps that are compatible across many networks and platforms.
Overall, DAML is an effective tool for creating safe, scalable, and interoperable smart contracts and decentralized applications (dApps) on platforms using distributed ledger technology.
The history of Digital Asset Modelling Language (DAML)
Digital Asset Holdings, a fintech company based in New York, originally unveiled the Digital Asset Modelling Language (DAML) in April 2016. The language was created as a high-level programming language for building distributed ledger technology (DLT) platforms, smart contracts, and decentralized apps (dApps).
The open-source blockchain technology Hyperledger Fabric, which was also created by Digital Asset Holdings, was the foundation upon which DAML was initially intended to operate. One of the first smart contract languages to be merged with Hyperledger Fabric was DAML, in fact.
Digital Asset Holdings soon discovered that DAML could also be applied to other DLT platforms, though. They made DAML SDK, an open-source version of the language that could be used with any DLT platform that supported smart contracts, available in 2018.
Since then, DAML has grown in recognition as a potent tool for creating dApps and safe, scalable smart contracts. Numerous significant DLT platforms, such as Corda, VMware Blockchain, and Hyperledger Sawtooth, currently support DAML.
The Digital Asset Modelling Language Foundation, an independent open-source initiative, was created in 2020 as part of a plan made by Digital Asset Holdings to spin out the DAML language (DAML Foundation). The goal of the foundation is to encourage the usage of DAML as a standard for creating dApps and smart contracts on DLT platforms.
How Digital Asset Modelling Language (DAML) works
Developers can create decentralized applications (dApps) and implement smart contracts using the high-level programming language Digital Asset Modelling Language (DAML) on platforms that use distributed ledger technology (DLT). Here is how DAML functions:
- Declarative Language: Because DAML is a declarative language, programmers express their goals rather than how to get there. This enables developers to concentrate on the application’s business logic rather than the underlying technological aspects.
- Contract-Oriented: Since DAML is contract-oriented, programmers create smart contracts to specify the conditions and terms of a transaction. With smart contracts, the details of the agreement between the buyer and seller are directly encoded into lines of code. These contracts self-execute.
- Multi-Party Workflows: Since DAML allows such workflows, programmers are able to create smart contracts that include several parties, each of whom has specific roles and obligations. This enables programmers to automate intricate financial procedures including supply chain management, insurance, and trade finance.
- Platform-Agnostic: Because DAML is platform-agnostic, smart contracts created with it can operate without any changes on various DLT systems. This makes it simpler for developers to design dApps that are compatible across many networks and platforms.
- Type-safe: Because DAML is type-safe, developers can identify mistakes at compilation rather than during execution. This lowers the possibility of problems and facilitates the creation of secure and reliable smart contracts.
- DAML is connected with a software development kit (SDK) that offers tools and libraries for developing, testing, and deploying dApps and smart contracts. A sandbox environment is also offered by the SDK for testing smart contracts and mimicking network activity.
Overall, DAML is an effective tool for creating safe, scalable, and interoperable smart contracts and decentralized applications (dApps) on platforms using distributed ledger technology. A high-level programming abstraction and multi-party workflow support are provided by DAML, which makes it simpler for programmers to design intricate financial and legal instruments.
What blockchain is DAML on
The platform-agnostic programming language known as Digital Asset Modelling Language (DAML) can be utilized on a variety of distributed ledger technology (DLT) platforms, including blockchain.
Several significant DLT platforms, including Hyperledger Fabric, Corda, and VMware Blockchain, support DAML. Each of these platforms has a unique consensus algorithm and blockchain implementation that governs how transactions are verified and added to the blockchain.
Developers can create smart contracts and decentralized apps (dApps) without having to be concerned with the technical specifics of the blockchain since DAML adds an abstraction layer over the implementation of the underlying blockchain. Any DLT platform that supports DAML can execute smart contracts written in it without any changes.
To summarize, DAML may be used to create safe and scalable smart contracts and decentralized applications (dApps) on a variety of DLT platforms, including blockchain.
