Cryptocurrency and blockchain technologies

In 2025, the crypto market reached a mature stage. Smart contracts have become part of everyday architecture, metaverses have gained influence, and digital assets have become the standard in business. In this context, the question of what NFT tokens are has become particularly relevant: not as a passing trend, but as the basis for the digitalization of rights, identity, and ownership in the Web3 economy.

What are NFT tokens?

NFT (non-fungible tokens) means “non-fungible tokens”. Each of them represents a separate digital object recorded on the blockchain. Unlike fungible tokens (e.g. USDT, ETH), which can be exchanged one-to-one, each NFT has an individual identifier and metadata that cannot be forged or cloned.

What are NFT tokens in technical terms? They are records in a smart contract with built-in information: authorship, creation date, file URI, license, and transaction history. This structure makes possession a proof of authenticity, unrepeatability and ownership, which cannot be lost or replaced by a simple copy.

The Market in 2025: Reinvented

By 2025, the NFT market will have abandoned inflationary collectibles and focused on utility objects. The focus has shifted from art and advertising to practical solutions. Asset owners will gain access to services, features, leasing, DAO voting, rating verification, and even digital identity. What are NFT tokens today: a club pass, an event ticket, a letter of credit, a subscription, a certificate, API access, or a share on a decentralized platform? Instruments have become legally meaningful objects with respect to corporate law.

Practical application: what are NFT tokens?

NFTs are used in logistics, real estate, education, insurance, music, film, and sports. Thanks to tokenization, the design, distribution, and control of assets have become dozens of times easier. By 2025, the asset will be used as:

a key to launching applications and subscriptions (access via token);

• a voting tool in DAOs and decentralized games;
• KYC identification element without revealing personal data;
• registration of intellectual property rights;
• digital receipt of a financial loan;
• access to a rented physical or digital asset;
• certificate of completion of a course or exam;
• Internal currency of the metaverse with a specific purpose.

Smart contracts and the ERC standard

NFTs are created according to the ERC-721 standard (or derivatives ERC-1155, ERC-3525, etc.). The standards define which functions a token must support: verification of the owner, translation, URI binding and creation and destruction events.

At the smart contract level, the functionality is fully automated. The owner has the ability to freely dispose of the token, independently of a third-party intermediary. It can be transferred, sold, burned, delegated or used as collateral in DeFi protocols. What are NFT tokens in the eyes of a developer? An object with a clear ABI interface and integration into the blockchain infrastructure. No bank, registrar or notary approval is required for its implementation. The code automates everything.

Law and identity: the new role of NFTs in the digital society

The legal recognition of NFTs is a logical step in the digital transformation. In 2025, the token began to fulfill the function of digital identity. Instead of usernames and passwords, users provide a token that is linked to a wallet and confirmed by a series of smart contracts. NFTs have become not only an asset, but also an ‘identity key’: a digital signature, a business card and an ID in one.

In education, objects such as diplomas are used. The admissions committee, employer or client receives an NFT certificate with immutable metadata: course name, study hours, completion date and name of the teacher. This excludes forgery and makes it easier to verify data.

What are NFT tokens in metaverses: building blocks?

The gaming industry continues to use NFTs as modular components in virtual worlds. Virtual lands, buildings, skins, artifacts, and contracts are created as assets, allowing the user to own and control the content created in the game outside of the platform. Players sell character skins, rent out arenas, collect equipment in the form of tokens, and use them in projects ranging from role-playing games to e-sports. In metaverses, NFTs fulfill multiple functions: land rights, event tickets, access to private clubs, personalized avatars, and branded visuals.

Financial ecosystem: DeFi and NFT in one package

Decentralized finance (DeFi) goes beyond using NFTs as art. Tokens have become collateral in lending protocols, a guarantee for launching new projects, and a digital asset that can be fractionalized, traded, and used to generate liquidity. A project with real estate-backed NFTs gives investors access to rental income. On DeFi platforms, you can earn interest with tokens, participate in staking or receive an airdrop that you can store in your wallet.

Markets and infrastructure: a system of mature solutions

To work with NFTs in 2025, a whole range of tools are used: wallets (MetaMask, Rabby, Phantom), marketplaces (OpenSea, Rarible, LooksRare), collection generators, API integrations, minting tools and airdrops.

Smart contracts are created in visual designers without code. Object owners subscribe to automatic actions: notifications, updates, rollups, DAO participation. What are NFT tokens in this context? An interface between the user and the platform, secured by the blockchain. Thanks to the infrastructure, any brand could launch them without the intervention of a programmer. This is the democratized Web3. Token creation, metadata management, and connection to registries have been simplified, and cross-chain support has been introduced.

Copyright: Protection of content in digital media

Creators use NFTs as a legally meaningful mechanism to protect rights. An artist, musician, or writer obtains authorship of a digital work through a smart contract. The token records the date of creation, the hash file, the creator’s name, and metadata. These are all stored on the blockchain and cannot be edited. This makes counterfeiting impossible and disputes easy to resolve. What are NFT tokens for content creators in 2025? The act of registration. The creator is given a tool that replaces the notary, lawyer, and copyright registry. Marketplaces support royalty payments. When assets are resold, a percentage of the proceeds is automatically transferred to the author. This mechanism provides passive income and makes creativity not only free, but also permanently monetizable.

Business Challenges: B2B Value

Companies are implementing NFTs for access control, employee certification, transaction verification and customer loyalty. Each employee card or specialist badge is issued as a token. Access to sensitive information, areas, files or equipment depends on the presence of assets in the wallet.

Retail chains use them as bonus cards. The customer receives a token with a purchase history, unique offers and the ability to upgrade. In the document flow of companies, these tools replace physical signatures and in logistics they record traces of goods movements. What are NFT tokens for companies? A tool to reduce costs, increase transparency and automate internal processes.

Conclusion

NFTs are no longer a hype. In 2025, they will be a technologically mature, legally formalized and economically applicable instrument. Each token is an encoded carrier of a unique digital or physical right. They are used in education, the gaming industry, finance, law, business and identity management. What are NFT tokens today? A bridge between the digital and the real world. They register authorship, provide access, manage rights, facilitate interaction and generate trust. The era of superficial views on tools is over.

The development of technologies continues unabated, and it is becoming increasingly important for each of us to understand them. In this article, we will try to explain in a simple, beginner-friendly way what blockchain is and how it works. This technology is the basis for most cryptocurrencies, such as Bitcoin and Ethereum, but its possibilities are not limited to the financial sector.

Historical background and development of technology

To understand what blockchain is and to be able to give a simple explanation to beginners, it is important to look at its history. In 2008, an anonymous developer under the pseudonym Satoshi Nakamoto introduced Bitcoin to the world, the first cryptocurrency that uses blockchain technology to store data. The idea was to make the system decentralised and transparent, so that no one could change the data without the consent of all network participants. This concept immediately attracted attention and revolutionised the financial world.

Before the advent of blockchain, all data was stored in central systems: banks and companies managed the information. The new format offers a solution where there is no need for intermediaries and network participants can communicate with each other directly, securely and without the risk of counterfeiting. With the development of blockchain, it was not only used for cryptocurrencies, but also in other areas: logistics, healthcare and art.

What is blockchain in simple terms? – Explained for beginners

The technology consists of a chain of blocks, each block storing information about a transaction. Each block is linked to the previous one by a cryptographic hash: a unique string that links the blocks together into an unbroken chain. If someone tries to change the data in a block, they change the hash and the entire chain becomes invalid.

How does blockchain work?

1. The transaction is the first thing that happens. For example, one person sends money to another.
2. Transaction verification: When a transaction is sent across the network, it is verified by other participants (or ‘nodes’).
3. Block formation: When transactions are verified, they are combined into a block.
4. Proof of consensus: Network participants (or miners, in the case of proof of work) agree that a block is correct and add it to the chain.
5. Update ledger: The new block updates the ledger on all devices in the network and the transaction is considered complete.

Each block contains a link to the previous block. If you change the data in one block, you have to recalculate the data in the following blocks. This makes the system virtually invulnerable to hackers.

Advantages of blockchain technology

To answer the question of what is blockchain in simple terms for beginners, we should discuss the advantages of the platform. It is impossible to change data in the database due to the static nature of the records: any attempt to change one block leads to a violation of the integrity of the entire chain, which provides protection against forgery. The transparency of the system is ensured by the fact that all transactions are available for verification by every participant. This creates a high level of trust and allows for quick verification of transactions. Due to the absence of a central governing body, the blockchain is decentralized. This significantly reduces the risk of manipulation and ensures the stability of the system even if individual nodes fail.

The use of advanced cryptographic methods enables a level of data protection that is virtually invulnerable to external attacks. In addition, the use of smart contracts automates the execution of transaction terms without the intervention of intermediaries. This speeds up the process considerably, saving time and money. By eliminating intermediaries, transaction costs are significantly reduced, saving you money and time when making transactions.

Disadvantages of the system

Like any technology, blockchain has its disadvantages:

1. Scalability: The larger the network, the slower the transactions can be, requiring more computing power.
2. Energy consumption: Some blockchain systems, such as Bitcoin, require a lot of energy to maintain the network.
3. Difficulty of implementation: Using blockchain requires a certain level of technical knowledge, as well as a significant investment in infrastructure.

Application of technology

Blockchain is used in many different areas:

1. Financial services. The scheme underlies the cryptocurrencies Bitcoin and Ethereum. Blockchain systems enable bankless transfers, reducing costs and speeding up the process.
2. Logistics. Businesses can use technology to track products throughout the supply chain. This helps prevent fraud and improve transparency.
3. Identity management. Blockchain can be used to store and verify personal data in passports and driver’s licenses. It increases data security and eliminates the possibility of counterfeiting.
4. Voting. In some countries, blockchain is used to organize elections. This provides transparency and protects against fraud, because every vote is recorded on the blockchain and cannot be changed.
5. Smart contracts. Smart contracts allow for the automatic execution of transaction terms without intermediaries, saving time and costs.

Conclusion

Our simple, beginner-friendly explanation of what blockchain is means that anyone can understand the technology without having to learn a lot of new words. We also explain why blockchain is gaining popularity so quickly and is being applied in a variety of areas.

In the future, the system will continue to develop and find new areas of application that can significantly change the economy and everyday life. The application of blockchain in a variety of sectors, from finance to healthcare and government, underlines its versatility and potential. However, it is important to keep in mind that the technology is still in development and its implementation requires a careful approach and competent technical support.

Originally associated exclusively with cryptocurrencies, blockchain has evolved into a tool that can transform the way businesses, governments, and social systems work. Classifying systems is important to understanding their functionality and selecting the right scheme for specific tasks. Classifying blockchain technology into types helps identify the best models for different applications: finance, healthcare, logistics, and energy.

Type 1: Public blockchain: transparency and decentralisation in action

A public blockchain is an open, decentralised network where any participant can be part of the ecosystem, verify transactions and use internal resources. This approach offers high transparency, reliability and independence from centralised authorities.

Public networks are based on the principles of openness and equality. Anyone can connect, without having to go through complicated registration procedures or provide personal information.

Characteristics of public networks:

1. Decentralisation. Management is performed by multiple nodes in the network, to the exclusion of a single control.
2. Cryptographic protection. Each transaction is encrypted and recorded in an immutable log.
3. Transparency. All transactions can be viewed by any participant.

Examples

Some of the best-known representatives are Bitcoin and Ethereum. These networks set the standard for the entire industry:

1. Bitcoin, launched in 2009, was the first example of the use of a public blockchain. It provides secure storage and transfer of digital assets and protects data using the Proof-of-Work (POW) algorithm. It has a maximum processing speed of up to 7 transactions per second.
2. Ethereum focuses on creating decentralised applications and supporting smart contracts. The network is widely used in DeFi (decentralised finance) and NFT (non-fungible tokens) projects.

Challenges and limitations

Despite its advantages, the public type of blockchain has some limitations:

1. Scalability. Limited network bandwidth, especially at times of high demand.
2. Energy consumption. Using the POW algorithm consumes a lot of resources. The bitcoin network consumes about 130 terawatt hours of energy per year, equivalent to the energy consumption of a small country.
3. High cost. During periods of blockchain congestion, users face higher transaction costs. In 2021, Ethereum’s cost was $40 per transaction.

The format is actively used in cryptocurrencies, decentralised autonomous organisations (DAOS) and digital finance, demonstrating resilience and efficiency.

Type 2: private blockchain – a tool for internal transactions

A private blockchain, unlike a public blockchain, is a closed network with limited access, where participants are subject to strict verification. These systems are managed by one or more organisations, ensuring control and security of transactions.

Private blockchains are designed to solve business problems and are characterised by high speed, low cost and flexibility. Access to the technology is limited and management is concentrated in the hands of specific users or organisations.

Features:

1. Access control. Only authorised subscribers can perform transactions or view data.
2. High performance. Average transaction speed of up to 1,000 transactions per second.
3. Configuration flexibility. Ability to adapt network rules to business needs.
4. Power saving. Private networks use algorithms that consume fewer resources, such as Proof-of-Authority (POA) or Practical Byzantine Fault Tolerance (PBFT).

Application examples

The best-known platforms are:

1. Hyperledger. Hyperledger was developed by the Linux Foundation and is used in logistics, finance and healthcare. Its purpose is to track deliveries in real time. Hyperledger Fabric processes up to 20,000 transactions per second.
2. Corda. Platform aimed at the financial sector. Corda helps automate interbank settlements, reducing costs and speeding up transactions.

Comparison

Private types of blockchain compare favourably with public ones in a business environment, but also have limitations.

Advantages:

• High data processing speed;
• closed structure reduces risk of hacker attacks;
• lower security costs.

Disadvantages:

• Centralised management;
• limited decentralisation reduces user trust;
• vulnerability to insider threats.

Type 3: Hybrid blockchain – balance between privacy and openness

Hybrid blockchains are a unique combination of public and private technologies. This structure allows organisations to customise data access, offer open services to customers and protect internal processes. Systems can choose which information is public and which remains private.

Features:

1. Customisable access. Ability to customise the degree of openness of data.
2. Interoperability with public networks. Benefits of both technologies can be exploited.
3. Flexibility of application. The system is simultaneously suitable for private and public purposes.

Application examples:

1. Dragonchain. The system developed by Disney supports intellectual property protection and contract management. Dragonchain enables the integration of open and closed platforms and ensures high performance and security.
2. XinFin. A hybrid blockchain to optimise international trade. XinFin is used in logistics and finance and provides transparency and cost reduction.

Type 4: consortium blockchain – joint data management

A consortium blockchain is a network managed by a group of organisations, making it a partially decentralised technology. These networks establish trust between participants by sharing control and responsibility.

This type of blockchain focuses on sharing data between a limited number of users. Management of the network and validation of transactions are shared between different companies to reduce the risk of misuse.

Characteristics:

1. Partial decentralisation. The network is managed by a group of participants, ensuring equal rights and greater trust.
2. Transparency. All activities on the platform can only be inspected by specific nodes.
3. High performance. The speed of transactions is higher than public blockchains: it reaches several thousand transactions per second.
4. Flexibility. Adjustment of network parameters to adapt it to the specific objectives of the consortium.

Examples of use cases:

1. Quorum, developed on Ethereum, is used in supply chain management and financial transactions. This platform supports data privacy and is therefore sought after in the banking sector.
2. B3i (Blockchain Insurance Industry Initiative) is a project in the insurance sector. A consortium of large insurers is using the platform to simplify settlements between market participants and increase process transparency.

Conclusion

The classification of the technologies helps determine which approach best suits the needs of a particular task. Each of the four systems has unique features and application scenarios. Choosing the type of blockchain depends on the objective. For example, a public network is suitable for digital finance, while a consortium network is suitable for supply chain management. By understanding the differences, users can optimise the use of the technology to solve business problems.

Blockchain technology has revolutionized the way we store and process information. Its operation is based on a distributed ledger system, where data is recorded in blocks that are linked together in a chain using cryptographic hashes. Each new link contains information about the previous link. This consists of a continuous sequence that cannot be changed or deleted. This makes blockchain technology unique in guaranteeing security and transparency.

How Blockchain Technology Works: Basic Functions and Operations

Blockchain works on the principle of decentralization, which eliminates the need for a central server. All network participants have a copy of the ledger, eliminating the need for a single data management center. All information is encrypted using a special algorithm that generates a unique hash for each block. Any change in this section changes the hash, making it virtually impossible to forge.

For example, the proof-of-work (PoW) algorithm is used to record a transaction on the Bitcoin blockchain. In this, miners have to solve complex mathematical problems to confirm transactions. There is also a Proof-of-Stake (PoS) algorithm, where the probability of creating a new block depends on the number of coins a participant holds.

These systems guarantee the security and integrity of data, which makes them popular not only in cryptocurrencies, but also in other sectors.

Advantages and disadvantages of blockchain algorithms

Each algorithm has its advantages and disadvantages. Proof of work offers a high level of security, but requires enormous computing power and consumes a lot of electricity. For example, the Bitcoin network consumes about 110 TWh per year, more than some countries consume.

Unlike PoW, Proof-of-Stake is more efficient and faster, but less secure against potential attacks. This has certain disadvantages when used in heavily loaded networks. Nevertheless, the characteristics of blockchain technology make it possible to tailor algorithms to specific tasks, striking a balance between speed, security and cost.

Advantages of Blockchain: What makes it unique?

Blockchain technology stands out due to its unique advantages over traditional databases. The most important ones are transparency, decentralization and security.

Technology that creates trust

Every network participant can trace the transaction history from the first link. In the banking sector, this helps combat fraud and increase customer trust. For example, blockchain-based systems are used to verify payments and process smart contracts.

Security is ensured by cryptography and distributed data storage. It is impossible to change the information in a section without changing the entire text. Piracy is therefore virtually impossible.

Advantages for participants in the process

The system eliminates intermediaries, which reduces costs and streamlines data processing. It allows the movement of goods in supply chains to be monitored in real time and minimizes the risks of loss and counterfeiting in logistics.

Blockchain also increases the scalability of networks. For example, new solutions such as the Lightning Network make it possible to process thousands of micropayments per second, thus reducing the load on the main network.

Disadvantages of blockchain: the other side of the coin

Despite its many advantages, the specific characteristics of blockchain technology entail certain limitations and create difficulties in its implementation.

Why is Blockchain often criticized?

One of the biggest problems is the high energy costs. Proof-of-work technology requires a huge mining power. For example, mining one Bitcoin transaction requires as much energy as the average American household consumes per month.

Scalability issues also limit the use of blockchain in high-load systems. For example, the Ethereum network can only process about 15 transactions per second, which is not suitable for large payment systems.

Risks of using data in the blockchain

Despite its decentralization, the blockchain is not protected against errors by network participants. If a user loses access to his or her wallet, it is impossible to recover the data. In addition, the lack of uniform standards makes it difficult to integrate blockchain into existing data management systems.

Blockchain applications: from cryptocurrencies to the public sector

The characteristics of blockchain technology allow it to be applied not only in the financial sector, but also in healthcare, logistics, and even in public administration:

1. Blockchain application in Russia. The method is currently being actively implemented in the country to create transparent voting systems, manage land registers, and streamline the flow of documents. In 2020, Moscow Exchange launched a blockchain platform for accounting digital assets. A comparison with foreign experiences shows that Russia is moving with the times and adapting blockchain technology to national characteristics and legislation.
2. Blockchain and cryptocurrencies: inextricably linked. The emergence of Bitcoin in 2009 was the first successful application of the method. Since then, this technology has formed the basis of thousands of cryptocurrencies. Each currency transaction on the network is recorded in blocks, ensuring transparency and security.
3. The future of blockchain in various sectors. The system has the potential to transform medicine, logistics and education. In healthcare, blockchain technology makes it possible to store and transmit medical data without the possibility of manipulation. In logistics, it simplifies product tracking and process automation.

Conclusion

The possibilities of blockchain technology offer new opportunities for companies and governments. The advantages of security, transparency and decentralization make the system an important method of the future. Despite the existing shortcomings, blockchain continues to develop and adapt to the needs of modern times.

Blockchain technology now extends far beyond cryptocurrencies. This innovative method of data storage offers transparency, security and decentralisation, making it attractive for a wide range of industries. Investing in blockchain is a strategic move today for anyone who wants to preserve and grow capital. Companies such as IBM, Microsoft and Amazon are already investing billions of dollars in the development of these technologies, which they see as the future of the digital economy.

The importance of blockchain is growing against the backdrop of the global economic crisis. In times of crisis and inflation, technologies that guarantee the security and reliability of data storage are crucial for businesses. In this article, we discuss promising blockchain projects, startups, ETFS and security tokens.
