1. Introduction: The Paradigm Revolution of Blockchain Crypto Assets

Under the continued impact of the digital wave, Blockchain Crypto Assets, as an emerging technological force, are reshaping the global economic and social landscape in an unprecedented manner. Blockchain, the distributed ledger technology known as the ‘trust machine,’ has evolved since its first proposal by Satoshi Nakamoto in the Bitcoin whitepaper in 2008, from simply supporting digital currencies to a universal technical architecture covering finance, supply chain, healthcare, government affairs, and other fields. Its core features, such as decentralization, immutability, distributed consensus, and smart contract automatic execution, have broken the traditional trust-building model relying on third-party intermediaries, making it possible for value to flow directly, securely, and efficiently between network nodes.

Cryptocurrencies, as the vanguard application of blockchain technology, were pioneered by Bitcoin. With decentralized issuance and trading mechanisms, they challenge the traditional pattern of fiat currency systems monopolized by central banks for issuance and regulation. Subsequently, numerous cryptocurrency projects like Ethereum have emerged in rapid succession, enriching the variety of digital currencies. By introducing smart contracts, they have built an open financial innovation platform for developers, giving rise to decentralized finance (DeFi), non-fungible tokens (NFT), and other emerging financial ecosystems. These innovative applications have attracted a large number of investors, entrepreneurs, and technology enthusiasts globally, driving the total market value of the cryptocurrency market to surpass the trillion-dollar mark at its peak, becoming an emerging force in the financial sector that cannot be ignored.

In the grand narrative of Web3, blockchain crypto assets play a foundational role. Web3 aims to build a decentralized internet where users truly own data, have autonomous control over identity and assets. The distributed ledger of blockchain ensures secure and transparent data storage, while crypto assets serve as a medium of value exchange and incentive tools, supporting the economic cycle of the entire ecosystem.

From a societal perspective, blockchain crypto assets bring a ray of hope for financial inclusion expansion. Globally, billions of people still lack access to traditional financial services such as bank accounts and credit support. Leveraging the internet, crypto assets enable anyone with a smartphone and internet connection to participate in global financial transactions, facilitating cross-border remittances, savings, and investments, lowering the barriers to financial services, and empowering economically disadvantaged groups. Furthermore, in the realm of sustainable development, blockchain crypto assets demonstrate unique value by tracking carbon emissions through smart contracts, supporting financing for green energy projects, providing new technological pathways and economic models for addressing climate change and promoting green development.

2. Deconstructing the Technical Foundation: Core Architecture and Innovation Breakthrough of Blockchain Cryptocurrency

2.1 Layered Technical Architecture

2.1.1 Data Layer: Chain structure and timestamps ensure data traceability

The data layer of the Blockchain is the foundation of the entire technical architecture, storing data in a chain-like structure. Each data block contains the hash value of the previous block, and the blocks are connected in chronological order through hash pointers to form an immutable transaction chain. Taking the Bitcoin Blockchain as an example, a new block is generated approximately every ten minutes, recording multiple transaction information within that time period, such as the addresses of the transaction parties, transaction amounts, etc. This chain-like structure gives the data natural traceability, allowing any transaction to be traced back by querying its complete history through block hashes.

A timestamp is another key element of the data layer, marking the exact creation time of each block. The timestamp is not only an important basis for transaction sequence but also enhances the credibility and tamper resistance of the data. In the application scenarios of Ethereum smart contracts, timestamps can be used to determine the execution time of contracts, the time of fund arrival, and more. For example, in decentralized financial lending protocols, key information such as loan terms and repayment times rely on timestamps for precise definition, ensuring the protection of the rights and interests of both borrowers and lenders. Any attempt to tamper with transaction times will be easily detected due to changes in hash values.

2.1.2 Network Layer: P2P Networking and Consensus Mechanism Ensure Decentralized Verification

The network layer of Blockchain is built on P2P (peer-to-peer) technology, where nodes are interconnected to form a distributed network structure. In this network, there is no centralized server, and each node equally participates in data transmission, verification, and storage, greatly enhancing the system’s resistance to attacks and fault tolerance. In the Litecoin network, nodes from around the world communicate with each other via the P2P protocol to collectively maintain the stable operation of the blockchain. Even if some nodes fail or are attacked, other nodes can still function normally, ensuring the uninterrupted operation of the entire network.

The consensus mechanism is the core of the network layer, which solves the problem of how to achieve consensus on the generation of new blocks among numerous nodes in a distributed environment. Taking the proof of work (PoW) mechanism adopted by Bitcoin as an example, nodes (miners) compete for the right to book new blocks by solving complex mathematical problems. Only the node that first finds a hash value that meets the conditions can add the new block to the blockchain and receive the corresponding Bitcoin reward. This mechanism ensures the security and decentralization of the blockchain, but it also has problems such as high energy consumption and slow transaction processing speed. In order to overcome these shortcomings, new consensus mechanisms such as proof of stake (PoS) and delegated proof of stake (DPoS) have emerged. In the EOS blockchain, the DPoS mechanism is used. Users holding EOS coins vote for 21 super nodes, and these super nodes take turns to generate new blocks, greatly improving transaction processing efficiency while reducing energy consumption.

2.1.3 Contract Layer: Smart contracts achieve automated rule execution

The contract layer is a key innovation of blockchain technology that distinguishes it from traditional distributed ledgers, mainly composed of smart contracts. Smart contracts are pre-written and deployed code on the blockchain, digitally defining the rights and obligations of all parties. Once the preset conditions are met, the corresponding operations will be automatically executed without the need for third-party intervention. On the Ethereum platform, smart contracts are widely used in various decentralized applications (DApps). For example, in decentralized crowdfunding projects, smart contracts can set conditions such as the fundraising goal and deadline. When the fundraising reaches the target amount and the deadline expires, the funds will automatically transfer to the project party; if the goal is not met, the funds will automatically be refunded to the investors. The entire process is open, transparent, with traceable execution results, effectively avoiding the trust risks and human errors that may occur in traditional crowdfunding models.

Smart contract programming languages are diverse, such as Solidity used by Ethereum, WebAssembly (Wasm) used by EOS, etc. These programming languages are Turing complete, capable of supporting complex business logic writing, providing developers with a broad space for innovation, and promoting the deep application and innovative development of blockchain in various fields such as finance, supply chain, and Internet of Things.

2.2 Core Technology Breakthrough

2.2.1 Asymmetric Encryption: Double Protection of Privacy Protection and Identity Authentication

Asymmetric encryption technology is the cornerstone of information security and user identity verification in the blockchain crypto asset system. It uses a pair of keys, namely public and private keys. The public key can be publicly distributed for encrypting information, while the private key is securely kept by the user for decrypting information and digital signatures. Taking Bitcoin transactions as an example, when user A transfers to user B, A uses B’s public key to encrypt the transaction information. Only B possessing the corresponding private key can decrypt and obtain the transaction details, ensuring the confidentiality of the transaction content during transmission and preventing third-party theft of information.

In terms of identity verification, digital signatures play an important role. Users use their private keys to sign transaction information, and the recipient or other nodes can verify the authenticity of the signature through the user’s public key. If the signature verification passes, it proves that the transaction was indeed initiated by the user and has not been tampered with, effectively preventing transaction repudiation and identity theft issues. In Ethereum smart contract calls, users need to use their private keys to sign the call instructions. The smart contract will verify the signature before execution, and only execute the corresponding operation if the verification passes, ensuring the security and reliability of smart contract execution.

2.2.2 Consensus Algorithm Evolution: Balancing Efficiency and Security from PoW to DPoS

As one of the core technologies of blockchain, the consensus algorithm reflects the continuous pursuit of balancing efficiency and security. In the early days, Bitcoin adopted the PoW consensus algorithm, where nodes compete to solve complex mathematical problems to gain the right to record transactions. Although this method ensures a high degree of decentralization and security, it comes at a high energy cost and slow transaction processing speed. Bitcoin confirms a block every 10 minutes on average, with only about 7 transactions processed per second, making it difficult to meet the needs of large-scale commercial applications.

To improve efficiency, the Proof-of-Stake (PoS) algorithm emerged. The PoS algorithm determines the right to bookkeeping based on the amount and holding time of the cryptocurrency held by the node. The more coins held and the longer the time, the greater the probability of being selected for bookkeeping. Compared to PoW, PoS reduces energy consumption because it does not require a large amount of computational power for mathematical calculations. However, PoS also faces issues such as ‘the rich get richer’ and unfair initial coin distribution, which may lead to a certain degree of centralization risk.

Delegated Proof of Stake (DPoS) is a further optimization based on PoS. Taking the EOS blockchain as an example, under the DPoS mechanism, users holding EOS coins vote to select a certain number (such as 21) of super nodes, which take turns to pack transactions and generate new blocks. This significantly increases transaction processing speed, with EOS theoretically capable of processing thousands of transactions per second, while reducing the entry barrier, allowing more ordinary users to participate in network governance through voting, achieving a good balance between efficiency and decentralization.

2.2.3 Merkle Tree and Zero-Knowledge Proofs: Improve the efficiency and privacy of data validation

Merkle tree is an efficient data structure used to quickly verify the integrity of data on the blockchain. It generates a hash value for each data block in the data set as a leaf node, then combines adjacent hash values in pairs, calculates the hash value again to form a new parent node, and so on until the root hash is generated. In the Bitcoin blockchain, each block contains a Merkle root. Through the Merkle tree, nodes only need to verify the Merkle root hash to quickly confirm the integrity of all transaction data within that block. For example, when a node needs to verify if a transaction exists in a certain block, it only needs to calculate hash values along the path of the Merkle tree from the leaf node to the root hash. If the calculated root hash matches the Merkle root in the block, it proves that the transaction exists and has not been tampered with, greatly improving the efficiency and accuracy of data verification.

Zero-knowledge proof is a technology that proves the truth of certain facts without revealing specific data content. In the application of blockchain crypto assets, it is mainly used to protect user privacy. Taking the Zcash crypto asset as an example, zero-knowledge proof allows users to prove the legitimacy of transactions to the network (such as having sufficient funds, transaction sources being compliant, etc.) without revealing sensitive information such as transaction amounts, transaction addresses of both parties, etc. This allows Zcash to protect transaction verifiability while maximizing user privacy, providing a more secure and anonymous trading environment for users who focus on privacy protection, and expanding the application boundaries of blockchain in the field of financial privacy protection.

3. Multi-dimensional application scenarios: The ecological expansion of blockchain crypto assets

3.1 Disruptive Reconstruction in the Financial Sector

3.1.1 DeFi (Decentralized Finance): Automated lending, liquidity mining reshaping financial services

DeFi, as the frontier application of blockchain encryption crypto assets in the financial field, is challenging the layout of the traditional financial system with its innovative financial model. Decentralized lending platforms represented by Compound realize the automation and disintermediation of the lending process through smart contracts. On the Compound platform, users only need to deposit crypto assets into the lending pool to obtain corresponding interest income according to the platform’s algorithm; borrowers can collateralize a certain amount of encrypted assets to borrow the required funds according to real-time market interest rates. The entire lending process does not require the participation of traditional financial intermediaries such as banks, greatly reducing transaction costs and time costs.

Liquidity mining is another innovative highlight in the DeFi ecosystem. Taking decentralized exchanges (DEX) such as Uniswap as an example, users provide cryptocurrency pairs (such as ETH-USDT) to liquidity pools to provide liquidity to the market, thereby earning a share of the trading fees and receiving liquidity mining tokens (such as UNI) distributed by the platform. This mechanism not only incentivizes users to actively participate in market making, improves the efficiency and depth of cryptocurrency trading, but also creates a new income model for investors. According to statistics, during the peak of the DeFi market, the annualized yield of some liquidity mining projects reached several hundred or even thousands of percentage points, attracting a large number of cryptocurrency investors worldwide, driving the total value locked (TVL) in DeFi to peak in 2021, exceeding 250 billion U.S. dollars, demonstrating the strong market appeal and innovative vitality of DeFi.

3.1.2 Cross-border Payments: Real-time settlement based on blockchain reduces transaction costs

In the traditional cross-border payment system, due to the involvement of multiple intermediary financial institutions, funds need to flow layer by layer between different bank accounts, resulting in high transaction fees and long processing times. The average cross-border remittance fee is as high as 5% - 10% of the transaction amount, and funds usually take 3 - 5 working days to arrive. Blockchain crypto assets have brought revolutionary changes to cross-border payments. Taking XRP from Ripple as an example, its blockchain-based cross-border payment network, using XRP as an intermediary bridge currency, enables fast exchange and cross-border transfers between different fiat currencies. When users initiate cross-border payments, funds are instantly transferred in the blockchain network in XRP form, and upon reaching the destination, they are exchanged into the local fiat currency, with the entire process taking only a few minutes and the transaction fees significantly reduced to a fraction of traditional methods.

In addition, the distributed ledger technology of blockchain makes cross-border payment transaction information publicly transparent and traceable. Every transaction is recorded on the blockchain, and both the payer and the payee can query the transaction status in real time, effectively solving the problems of information asymmetry and transaction opacity in traditional cross-border payments. This not only improves the security and credibility of cross-border payments, but also brings more efficient and convenient payment solutions to international trade, global remittances, and other fields, promoting the process of global financial integration.

3.2 Sustainable Development and Global Governance

3.2.1 Carbon Market Digitalization: Nori platform tracks carbon credit trading through blockchain

In the global effort to address climate change, the digitalization of the carbon market has become a key initiative, with the Nori platform being a typical representative. Nori utilizes blockchain technology to build a transparent and efficient carbon credit trading market, aiming to incentivize businesses and individuals to participate in carbon emission reduction actions. On the Nori platform, carbon credits exist in digital form, with each credit representing the right to remove one ton of carbon dioxide from the atmosphere. These carbon credits are registered, traded, and tracked on the blockchain through smart contracts.

When companies or individuals implement carbon reduction projects, such as investing in renewable energy, adopting low-carbon production technologies, etc., after third-party certification, they can obtain corresponding carbon credits and sell them to buyers with carbon offset demand. After buyers purchase carbon credits, their transaction information will be recorded on the blockchain, ensuring the authenticity, uniqueness, and traceability of carbon credits, effectively preventing the duplicate sale and fraudulent behavior of carbon credits. As of 2023, the Nori platform has facilitated the trading of thousands of tons of carbon credits, attracting participation from many well-known companies and environmental organizations, playing a positive role in promoting the global carbon reduction goals.

3.2.2 Public Welfare Transparency: Distributed ledger enables traceability of donation funds flow

The public welfare sector has always faced a crisis of trust, with the transparency of the use of donated funds and the tracking of their whereabouts becoming the focus of public attention. The distributed ledger technology of blockchain encryption crypto assets provides an effective solution to this problem. Taking The Giving Block platform as an example, it allows donors to use cryptocurrencies such as Bitcoin and Ethereum for charitable donations. The donation process is recorded on the blockchain, and the flow of each fund is clear and traceable.

When donors donate to charity projects, the transaction information is broadcast to various nodes in the blockchain network, forming an immutable record. After the charity organization receives the donated funds, the usage of the funds, including the purchase of supplies, payment of expenses, etc., will also be recorded on the blockchain. Donors can use the blockchain browser to real-time track the use and destination of the donated funds, ensuring that the funds are truly used for public welfare. This transparent donation model enhances donors’ trust in charity organizations, promotes the healthy development of public welfare, attracts more public participation in charitable donations, and provides strong support for solving social problems and promoting social fairness and justice.

3.3 Digital Assets and Metaverse

3.3.1 NFT Ecology: A New Paradigm for Digital Art Copyright and Trading

NFT (non-fungible token) as an innovative application of blockchain encryption currency in the field of digital assets, has brought a new paradigm for the ownership confirmation and trading of digital artworks. Taking CryptoPunks as an example, this is one of the earliest NFT projects based on the Ethereum blockchain. Each CryptoPunk is a unique digital image with distinctive appearance and attributes. These NFT works are confirmed on the blockchain through smart contracts, and each NFT has a unique identifier representing the ownership of the digital artwork by its owner.

In terms of trading, NFT trading platforms such as OpenSea provide users with convenient trading venues. Users can freely buy and sell NFT digital artworks on the platform, and the trading process is automatically executed through blockchain smart contracts, ensuring the security, transparency, and immutability of the transactions. For example, the famous digital artist Beeple’s work ‘Everydays: The First 5000 Days’ was auctioned at Christie’s auction house in the form of an NFT and eventually sold for a high price of $69.34 million, setting a new record in the digital art trading world, fully demonstrating the huge value and potential of NFTs in the digital art market. NFTs not only give unique ownership value to digital artworks but also provide new economic revenue models for digital creators, inspiring vitality and innovation in digital art creation.

3.3.2 Chain Gaming Economy: Projects like Aavegotchi incentivize the construction of a virtual world closed loop through tokens

The chain game economy is a emerging field that combines blockchain encryption assets with the gaming industry, and the Aavegotchi project is a leader in this field. Aavegotchi is a DeFi-powered NFT cultivation game based on the Aave protocol, where players can adopt and nurture their virtual pet Aavegotchi in the game. These pets exist in the form of NFTs, with unique attributes and value.

In the game world of Aavegotchi, players obtain in-game resources and rewards by staking crypto assets, such as items for feeding pets and experience points for leveling up pets. Additionally, players can earn the game’s native token GHST by participating in various activities within the game, such as exploring the virtual world and completing tasks. GHST can be used in-game to purchase virtual items, upgrade pets, and can also be traded on external crypto asset exchanges, effectively connecting the virtual world with the real economy. This token incentive mechanism establishes a self-sufficient virtual world economic ecosystem, where players invest time and energy in the game to receive economic rewards, further stimulating players’ enthusiasm and driving the development of blockchain gaming economy, bringing new business models and development opportunities to the gaming industry.

4. Challenges and Risks: Technological Bottlenecks and Regulatory Dilemmas

4.1 Limitations at the Technical Level

4.1.1 Scalability Challenge: Throughput Limitation Constrains Large-Scale Applications

The primary challenge that Blockchain Crypto Assets face at the technical level is the issue of scalability, with throughput limitations severely restricting widespread adoption. Taking Bitcoin as an example, as the earliest cryptocurrency, its use of the Proof of Work (PoW) consensus mechanism ensures decentralization and security of the network, but performs poorly in transaction processing capacity. The Bitcoin Blockchain generates a new block approximately every 10 minutes, with each block size limited to around 1MB, resulting in Bitcoin being able to process only about 7 transactions per second (TPS). In stark contrast, traditional payment giant Visa has a transaction processing capacity of up to 24,000 transactions per second, while PayPal can reach 193 transactions per second. Such a significant gap makes Bitcoin appear inadequate in daily large-scale payment scenarios, struggling to meet the high-frequency, high-volume transaction demands globally, limiting its application expansion in mainstream payment areas.

As a pioneer platform for smart contracts, Ethereum is also deeply troubled by scalability issues. Ethereum’s transaction processing speed is about 15-20 transactions per second. During the NFT boom and DeFi application outbreak in 2021, network congestion issues were particularly severe. A large number of users simultaneously interact with smart contracts, NFT transactions, and other operations, causing Ethereum network transaction fees to soar. The fees for some complex transactions can even reach tens of dollars. Many small-value transactions are delayed or canceled due to the inability to afford high fees, greatly impacting user experience and hindering further development of the Ethereum ecosystem.

4.1.2 Energy consumption controversy: Exploring the negative impact of PoW mechanism on the environment and alternative solutions

The process of mining blockchain cryptocurrency based on the PoW consensus mechanism has sparked widespread controversy over energy consumption. Under the PoW mechanism, miners need to compete for the right to record new blocks by continuously performing complex mathematical calculations, which requires a large amount of computing resources and electrical energy. According to data from the Cambridge Centre for Alternative Finance (CCAF) at the University of Cambridge, the annual electricity consumption of the Bitcoin network exceeds that of many countries, such as Argentina and the Netherlands, with an estimated annual electricity consumption of around 121.36 terawatt-hours. This data not only puts pressure on global energy supply but also runs counter to the current global advocacy of sustainable development.

High energy consumption also brings environmental problems such as carbon emissions. Due to the concentration of many Bitcoin mining farms in areas with low energy costs but mainly traditional fossil energy sources, such as China (before the relevant policy adjustments), Kazakhstan, etc., a large amount of coal, natural gas, and other fossil fuels are burned during the mining process, leading to increased emissions of greenhouse gases such as carbon dioxide, which negatively impact global climate change. To address this issue, the blockchain industry actively explores alternative solutions, with the Proof of Stake (PoS) mechanism becoming a popular choice. Ethereum successfully completed the transition from PoW to PoS in 2022. Under the PoS mechanism, validators obtain the right to record transactions based on the amount of cryptocurrency they hold and the duration of their holdings, without the need for extensive computational competition, thereby reducing energy consumption by over 99% and significantly improving the energy efficiency and environmental friendliness of the blockchain network. In addition, new consensus mechanisms such as Delegated Proof of Stake (DPoS) and Practical Byzantine Fault Tolerance (PBFT) continue to emerge, optimizing energy consumption issues to varying degrees and providing new technical paths for the sustainable development of blockchain cryptocurrencies.

4.2 Regulatory and Compliance Challenges

4.2.1 Legal Vacuum: Global Coordination Challenges in Defining the Attributes of Crypto Assets and Tax Policies

On a global scale, Crypto Assets face the dilemma of fuzzy legal status definition and difficult coordination of tax policies. Currently, there is no consensus among countries on the legal classification of Crypto Assets. The U.S. Commodity Futures Trading Commission (CFTC) considers cryptocurrencies like Bitcoin as commodities, while the U.S. Securities and Exchange Commission (SEC) determines whether certain cryptocurrencies are securities based on the Howey test. The European Union defines Crypto Assets as a ‘digital representation of value,’ not legal tender, but can be used as a medium of exchange. This inconsistent legal classification results in Crypto Assets facing different regulatory standards and legal risks in different countries and regions.

Tax policy also faces global coordination challenges. Crypto asset transactions are characterized by cross-border and anonymity, making tax management more difficult. Some countries treat crypto asset transactions as capital gains for taxation, such as the United States levying capital gains tax on crypto asset transactions, with tax rates based on holding period and income level; while other countries treat them as ordinary income for taxation, such as the United Kingdom levying profits from crypto asset transactions at the income tax rate. In addition, in cross-border transactions, how to avoid double taxation and prevent tax arbitrage has become an urgent issue to be addressed. Due to the lack of a unified international tax coordination mechanism, crypto asset investors and practitioners need to deal with complex and changing tax policies when operating in different countries and regions, increasing compliance costs and legal uncertainties.

4.2.2 Market manipulation risk: NFT price manipulation and frequent DeFi smart contract vulnerabilities

The rapid development of the crypto asset market has also brought market manipulation risks, with NFT price manipulation and DeFi smart contract vulnerabilities being common. In the NFT market, due to the lack of effective price discovery mechanisms and regulation, some projects engage in serious price manipulation. Some NFT creators or project parties create the illusion of active trading through self-trading, false trading, etc., inflate NFT prices, and attract uninformed investors. For example, in some NFT projects, project teams control multiple accounts and conduct high-priced transactions among themselves, driving NFT prices to artificially high levels. After ordinary investors follow suit and buy in, they then sell off to cash out, causing a sharp drop in NFT prices and resulting in significant losses for investors.

The DeFi sector is plagued by smart contract vulnerabilities, becoming a major target for market manipulation and hacker attacks. In 2022, Slope Finance, a DeFi project on the Solana blockchain, was attacked by hackers who exploited smart contract vulnerabilities, stealing approximately $3.7 million worth of encrypted assets. In 2023, the Nexera DeFi protocol was also hacked by hackers who stole approximately $1.8 million worth of digital assets due to smart contract vulnerabilities. These vulnerabilities not only result in user asset losses but also undermine market trust, affecting the stable development of the DeFi ecosystem. The complexity and tamper-resistant nature of smart contracts make it difficult to repair once vulnerabilities are discovered, allowing attackers to swiftly transfer assets and cause irreparable losses, highlighting the urgency of strengthening security audits and supervision of DeFi projects.

5. Future Outlook: Technology Integration and Ecological Co-construction

5.1 The Synergistic Development of Web3 and Metaverse

5.1.1 Semantic Enhancement Network: SemNFT technology solves the challenges of digital asset storage and verification

In the process of collaborative development of Web3 and the metaverse, the storage and verification of digital assets have become key challenges. SemNFT technology has emerged to provide innovative solutions to this problem. Although traditional NFTs endow digital assets with unique identity labels, they face storage challenges brought by the permanent data cost of blockchain. Off-chain or centralized storage solutions also have security risks.

SemNFT is an innovative decentralized framework that integrates blockchain oracle middleware services. In the off-chain part, data compression and feature extraction are performed through training autoencoder models, converting floating point arrays to integers to effectively reduce data storage space. In the on-chain part, NFTs are minted from the integer arrays and stored and managed on the blockchain, achieving unique identification and ownership tracking of digital assets within the decentralized ledger system. Taking digital art collection as an example, artists can mint their works as NFTs using SemNFT technology and store them on the blockchain. When collectors verify ownership of the works, they do not need to rely on external links to obtain metadata, and can directly verify through the information on the blockchain, avoiding the problem of verification failure due to link expiration or data tampering, ensuring the authenticity of digital art and the reliability of ownership, laying a solid foundation for the long-term preservation and circulation of digital assets in the metaverse.

5.1.2 Virtual-Reality Interaction Economy: 3D Crypto-dropout Technology Empowers Personalized Metaverse Experience

The core charm of the Metaverse lies in providing users with an immersive, personalized virtual experience. 3D Crypto-dropout technology plays an important role in this field, promoting the development of the virtual-real interactive economy. In Web3 Metaverse projects driven by blockchain, User Generated Content (UGC) is an important element in building a rich virtual world. However, existing UGC editors face challenges in ensuring content uniqueness and balancing model precision with modeling difficulty.

3D Crypto-dropout technology ensures the uniqueness of generated models by hashing user information and controlling the 3D model generation process with unique dropout units for each user. Taking virtual real estate construction in the metaverse as an example, when users use an editor with 3D Crypto-dropout technology to create virtual houses, the system will generate unique building structures, decor styles, etc., based on the user’s unique information, ensuring each virtual property’s uniqueness in the metaverse and avoiding homogenization. Additionally, this technology utilizes AI algorithms to assist model generation, reducing the complexity of 3D modeling and enabling ordinary users to easily create complex and exquisite virtual scenes, enhancing user engagement and creativity in metaverse construction. These unique virtual properties in the virtual real estate market attract more users for trading due to their uniqueness and personalized features, promoting the prosperity of the metaverse economic system and achieving deep integration between the virtual world and the real economy.

5.2 The dual drive of policy and technology

5.2.1 Central Bank Digital Currency (CBDC): The Convergence Path of Sovereign Currency and Blockchain Technology

In the global digital wave, Central Bank Digital Currency (CBDC), as the product of the integration of sovereign currency and blockchain technology, is gradually becoming the focus of the financial industry. CBDC is issued and regulated by central banks of various countries, aiming to meet the needs that traditional financial systems cannot meet, improve payment efficiency, reduce costs, enhance security, and anti-counterfeiting capabilities. Compared with traditional currencies, CBDC, based on blockchain’s distributed ledger technology, has characteristics such as decentralization, programmability, and traceability, which can effectively reduce intermediary costs in cross-border payments, increase transaction speed, and enhance transaction transparency and security.

Taking the pilot project of China’s digital RMB as an example, the digital RMB adopts a dual-layer operation system of “central bank - commercial bank”, utilizing blockchain technology to achieve real-time settlement and clearing, reducing the intermediary costs between central banks and commercial banks, and improving the efficiency of currency issuance. In retail payment scenarios, users can make convenient payments through digital RMB wallets, with transaction information recorded in real-time on the blockchain, traceable and tamper-proof, effectively preventing payment risks. At the same time, the programmability of digital RMB enables it to realize advanced functions such as smart contracts and automated payments, providing broad space for financial innovation. In terms of international cooperation, central banks of multiple countries are actively exploring the application of CBDC in cross-border payments, such as the Multilateral Central Bank Digital Currency Bridge (mBridge) project, aiming to seamlessly connect and efficiently circulate digital currencies of different central banks through blockchain technology, promoting the global financial integration process.

5.2.2 Cross-chain Interoperability: The cross-chain protocol between the Cosmos and Polkadot ecosystems breaks through

With the widespread application of Blockchain technology, the interoperability between different Blockchains has become a key bottleneck for industry development. The breakthrough in cross-chain protocols of Cosmos and Polkadot ecosystems brings a glimmer of hope to solve this problem. Blockchain interoperability refers to the ability for different Blockchains to interact, share information, and assets. Currently, Blockchains such as Bitcoin and Ethereum are independent of each other, forming information silos, hindering the expansion and innovation of Blockchain applications.

Polkadot claims to be a Web3 platform, using a architecture of parallel chains and relay chains to achieve interoperability between blockchains. The relay chain is the main Polkadot blockchain, with its native asset as DOT, used for governance and Staking; parallel chains can seamlessly connect to the relay chain, with each parallel chain having its own typical characteristics such as governance and tokens. By connecting to the relay chain, tokens from one parallel chain can be seamlessly sent to another parallel chain, achieving interoperability between multiple chains. Although Polkadot only supports 100 different parallel chains, it has certain limitations, but it is creating bridges to enable established blockchains such as Bitcoin and Ethereum to interact with the Polkadot ecosystem.

Cosmos, developed by software company Tendermint, aims to create a hub where all Tendermint blockchains can interact. The Cosmos Tendermint consensus protocol, Cosmos SDK development framework, and IBC cross-chain protocol are seen as the three major technological innovations in the blockchain field. Among them, the IBC cross-chain protocol has opened a new door for Cosmos ecological projects, enabling asset transfer and information exchange between different blockchains within the ecosystem. For example, Terra, an application chain based on Cosmos, whose stablecoin UST once held a significant position in the crypto market, can now connect with other blockchain networks through the IBC protocol, allowing users to send and receive assets across chains, promoting the prosperity of the Cosmos ecosystem. In the future, Cosmos and Polkadot are expected to further develop and even jointly create cross-chain bridges to achieve full interoperability with more large-scale blockchains, building a more open and inclusive blockchain ecosystem.

6. Case Study: Technical Path and Market Insights of Typical Projects

6.1 Bitcoin: The Foundation of Decentralized Currency

Bitcoin, as the pioneer of blockchain encrypted crypto assets, has profoundly changed the global financial landscape since its birth in 2009 with its decentralized monetary system and innovative technological architecture. The technical path of Bitcoin is based on a decentralized distributed ledger, ensuring the consistency and security of transaction records among nodes in the network through the Proof of Work (PoW) consensus mechanism. In the Bitcoin network, each node has a complete copy of the ledger, and transaction information is linked in blocks in chronological order to form an immutable historical record.

From a market performance perspective, Bitcoin has demonstrated strong potential for value growth over the past decade. Despite the sharp price fluctuations, its long-term trend shows a significant upward trend. Taking the period from 2010 to 2024 as an example, the price of Bitcoin has soared from a few cents initially to tens of thousands of dollars, with a market value once surpassing the trillion-dollar mark, becoming the focus of global investors’ attention. The success of Bitcoin lies not only in its value storage and transactional functions as a new type of digital currency but also in its pioneering of decentralized finance, laying a solid foundation for the development of subsequent blockchain projects, indicating the enormous potential of blockchain technology in the financial sector for decentralization, enhancing transaction efficiency, and ensuring information security.

6.2 Ethereum: Ecological Expansion of Smart Contract Platform

Ethereum has an important milestone significance in the development of blockchain. It was launched in 2015, and it first introduced smart contracts into the blockchain field, building an open decentralized application (DApp) development platform. The technical core of Ethereum lies in its Turing-complete smart contract programming language Solidity. Developers can use this language to write various complex smart contracts, realizing automated business logic and value transfer. This expands Ethereum’s application scenarios from simple digital currency transactions to finance, supply chain, gaming, social and other fields.

In the market, Ethereum has attracted a large number of developers and projects worldwide with its rich ecosystem.
