A Comprehensive Guide to Understanding the Basics of EOS … – The Coin Republic
With the introduction of its first initial coin offering (ICO) in July 2017, the EOS blockchain shook the blockchain world with its entrance. The smart contract environment of the EOS allows businesses and industries to develop scalable decentralized applications (dApps) in a way similar to web-based applications. This blockchain supports diverse features and has been a potential competitor of both market leaders (Ethereum) and newcomers (Tron and Neo).
First launched in 2017 by Block. One company, EOS (short for the electro-optical system), is a blockchain-based decentralized platform that operates on a Delegated-Proof-of-Stake (DPoS) consensus mechanism and is used to build a wide range of industrial-scale dApps and ecosystems.
The robust and agile infrastructure of EOS blockchain provides a user-friendly and business-friendly environment to create dApps while avoiding the issues of high fees and slow transaction speeds of traditional blockchains (e.g., Ethereum).
The EOS network has two key elements:
EOS blockchain has been embraced by the blockchain community. Ubuntu Energy Ledger, All_ebt Food Stamps, and DACTROIT are some of the numerous applications that have been built on the EOS platform.
Before starting to trade on the EOS blockchain, users need to create an EOS wallet that can send and receive EOS tokens while also storing private-public key pairs. The most popular EOS wallet examples include Exodus Mobile, MyEOSwallet, Guarda, and Scatter.
In 2016, Ethereum suffered an infamous DAO hack in which hackers exploited a code vulnerability of the blockchain and stole coins worth around $60 Million leading to the creation of a hard fork called Ethereum Classic.
The DPoS mechanism protects the EOS blockchain from such security threats since it involves elected delegates who continuously monitor the network and can freeze faulty dApps.
Processing any transaction on a PoS-mechanism-based blockchain network requires the consensus of all network nodes, reducing the number of transactions executed per second (TPS), also known as scalability.
EOS blockchain officially reaches a transaction capacity of 100,000 TPS, which is significantly higher than its opponents, such as Visa (1700 TPS), PayPal (193 TPS), Ethereum (27 TPS), and Bitcoin (7 TPS).
EOS network achieves higher transaction rate via- horizontal scaling, i.e., adding more systems to its network to widen its resource pool; vertical scaling which involves boosting the computing power of specific parts of the network or dApps.
Transactions on the Ethereum blockchain require the user to pay the gas fee, which gets more expensive as more people use the network.
The working of the EOS blockchain differs in this regard as it bestows its users ownership of the network resources (e.g., computing power) in direct proportion to the tokens they hold. This method replaces the payments for individual transactions.
Creating custom smart contracts and permission schemes for various businesses is the primary focus of the EOS network.
The comprehensive permission system of EOS can be used by developers to safeguard specific smart contract features. Moreover, this crypto platform offers the feature of splitting authorities required to invoke a smart contract function, across different accounts with different command weights.
All EOS-based apps are upgradeable and modifiable meaning users can implement code fixes, and make additions or changes in the applications features and logic. Moreover, rather than dealing with permanent bugs, the EOS network allows developers to renew their dApps.
The parallel processing of EOS smart contracts can be achieved by three prominent features. First, through asynchronous communication, transaction parties need not be present simultaneously to communicate.
Secondly, the interoperability feature enables the smooth transfer of data and information between two blockchains.
Thirdly, the horizontal and vertical scaling options of the EOS enhance the transaction capacity of the network.
Ups and downs of EOS blockchain
During its 2017-2018 ICO, EOS raised the equivalent of around $4 Billion by releasing over 700 Million tokens. However, its user base started shrinking after four years. Moreover, the value of the EOS token toppled from $10 in June to $4.46 in August 2021.
Presently, the EOS blockchain has become the most widely used blockchain-based network worldwide. With its permissioned and enterprise-scale nature, it is becoming a platform that can provide several benefits to businesses and industries.However, there are still some doubts and criticisms from the blockchain community members regarding the undelivered promises and degrading quality of EOS.IO code that need to be addressed.

Blockchain platforms promise resale royalties and provenance … – Art Newspaper
Nine years after the launch of the second generation of blockchain, the technology has found a new life as a home for digital contracts. Artists and the art market have started to see delivery of the promise that blockchainon which digital transactions are permanently recordedcan serve as a permanent record of a physical works authenticity, while also setting the terms for a secondary sale to benefit the works creator beyond the primary sale.
That promise derives from blockchain-powered ventures in other industries that are also trading high-value items, notably Everledger, founded in 2015, which secures records of authenticity and ethical sourcing for diamonds by tracking their provenanceincluding a digital twin of each gemfrom mine to jewellers shop, through unalterable files held on a blockchain.
The art market, which enjoyed a rollercoaster first engagement with the blockchain as a home to non-fungible tokens (NFTs)digital tokens that sold at eye-popping speculative levels in 2021has been offered a new engagement with the technology in the past year, with the emergence of platforms devoted to using blockchain tohost a digitised version of the established interaction between artists, dealers and collectors, in buying and selling new physical works of art.
The benefits on offer are a permanent record of authenticity and transparency of a transaction, to buyers and sellers alike, and allowing artists to set contractual terms, held on the blockchain, for the secondary sale of their work. (Makers of physical art will be looking to learn from the recent experience of those NFT artists who have sold their digital art on one blockchain but have then missed out on the terms of the resale royalties when the buyer has sold the piece on another blockchain.)
Two of the leading players in the field are Fairchaina US-based start-up, founded by artists and Stanford University graduates, which since 2021 has offered blockchain-stored certificates of authenticity and royalties on resaleand Arcual. The latter, a blockchain-powered platform, backed by the LUMA Foundation, MCH Group (owners of Art Basel) and BCG X (the tech venture arm of Boston Consulting Group) bases its process on a double-signed agreement, the certificate of authenticity, between dealer and artist. These certificates always include multiple signatures, Arcuals chief product officer, Rodrigo Esmela, and its chief technical officer, Michael Schuller, tell The Art Newspaper. This means, they say, that parties cannot unilaterally define terms or conditions, allowing galleries and artists to define the accurate representation of the artwork on the blockchain and the terms and conditions of any sale or resale.
Works by Phoebe Cummings will be used by Arcual to demonstrate its digital dossiers at Art Basel Sylvain Deleu
Seven months after its launch, Arcual has introduced digital dossierswhich it will demonstrate at Art Basel with the work of the ceramic artist Phoebe Cummingsthat enable artists to add text, images and PDF files to create a rich provenance, recording anything from the works creation to the artists intentions for its display. The information is as unalterable on the blockchain as its certificate of authenticity, and part of a smart contract between artists, dealers and collectors. (Arcual can handle transactions of up to $1m at a time and takes up to 1.5% in commission on each sale.)
Bernadine Brcker-Wieder, Arcuals chief executive, worked closely with Everledger in her previous role as founding chief executive of Vastari, the worlds largest private collection and temporary exhibition database, which took an investment in 2016 from Everledger. She says that, in conversations with artists, dealers and collectors, the word blockchain now hardly arises; the tech has almost become a given. And while blockchain-stored contracts designed for other industriesfashion, luxury, shipping containersmight depend on additional layers of tech to link contract and object, such as the creation of a digital twin or the adding of an NFT chip to high-value fashion items, in Arcuals digital dossier an artist can record uniquely personal marks of authenticity. These might be a hard-to-detect symbol or a surface abrasion that forms part of a pieces unique physical make-up, added by the artist for an extra level of authenticity. The Arcual dossier is like a users manual of the work, Brcker-Wieder says.

Arcuals digital dossiers are necessarily private to artist, dealer and collector, but the potential shape of such richly detailed provenances can be seen in platforms for other industries, including findmyinstrument.org, a website where the detailed history and physical characteristics of historic violins, violas and cellos, are published, using X-rays, infrared, endoscope imagery, photographs, video and written descriptions. Of course, storing large volumes of detailed information raises questions about data laws, especially in relation to the GDPR that prevails in Europe and the UK. Questioned about this by The Art Newspaper, Esmela and Schuller said that Arcuals digital dossiers and other information held on the blockchain is compatible with GDPR. We only store the minimum required information. No personal identifiable information (PII) about buyers is stored in the digital dossier, and only information relevant to the artwork is stored in the digital dossier.
Artclear, another new blockchain platform for recording a permanent provenance for art, offers a technical model closer to the Everledger digital twin approach, by providing microscopic-level scanning of works using industry-standard tech under licence from the hardware giant Hewlett-Packard (HP). The scan, and a digital code derived from it, is saved on the blockchain as part of an Artclear Fingerprint.
Ceramic works by Athene Galiciadis were consigned by Arcual earlier this yearCourtesy of von Bartha Gallery Copenhagen
These new blockchain-based businesses have caught the attention of the market. At Art Basel in Hong Kong in March 2023, eight galleries consigned work through Arcuals Salesroom platform, including Sabrina Amrani gallery with Carlos Aires and his sculpture Bon Apptit IV (2022), an assemblage of glassed porcelain plates, and Commonwealth and Council gallery with Kenneth Tam for his video Silent Spikes (2021). For Stefan von Bartha, the owner of Von Bartha gallery, which used Arcual to consign a Copenhagen exhibition of Athene Galiciadiss painted clay vessels, Measuring the World, earlier this year, using the platform is part of striving for a more transparent and fairer art world.
As with all manner of new tech platforms over the past 15 years, whether in the art market, publishing, or gaming industries, potential customers of Fairchain, Arcual and other entrants to the field, are to different degrees enthused by the tech and wary of how it will reach critical mass. The London gallerist Oliver Miro, founder of Vortic, a VR and AR platform for the art world, recognises the potential of the technology but wonders whether this approach will work unless the whole art world shifts to one model and one blockchain, and enforces it rigorously.

The Rise of Decentralized Finance: Exploring DeFi and its Potential – Global Banking And Finance Review
What is Decentralized Finance (DeFi)
Decentralized finance, also known as DeFi, is a growing industry that allows users to access financial services without intermediaries. DeFi aims to provide a more open, transparent, and accessible financial system using blockchain technology and smart contracts. This article explores the history, advantages, protocols, challenges, and future of DeFi.
DeFi is a decentralized financial system that allows users to access financial services without intermediaries such as banks, brokers, or exchanges. DeFi operates on blockchain technology, which enables secure and transparent transactions without the need for a central authority.
DeFi originated in 2017 with the launch of the Ethereum network, which enabled the creation of smart contracts and decentralized applications (dApps). The first DeFi application was MakerDAO, which introduced a decentralized stablecoin called Dai. Since then, the DeFi industry has grown rapidly, with a market cap of over $100 billion as of May 2023.
DeFi offers numerous benefits such as accessibility, transparency, security, efficiency, and flexibility.
DeFi (Decentralized Finance) offers increased accessibility to financial services. With DeFi, anyone with an internet connection can access a wide range of financial services, such as lending, borrowing, trading, and investing. This accessibility is particularly beneficial for individuals who are unbanked or underbanked, as they can participate in financial activities without relying on traditional banking systems.
One of the key advantages of DeFi is its transparency. DeFi transactions are recorded on a public blockchain, which means that anyone can view and verify the transactions. This transparency helps build trust among users, as they can independently verify the integrity of the transactions and ensure that the system is operating fairly.
DeFi offers enhanced security compared to traditional financial systems. By utilizing blockchain technology, DeFi eliminates the need for intermediaries and central authorities, reducing the risk of hacks, fraud, or manipulation. Additionally, DeFi platforms often implement smart contracts, which are self-executing contracts with predefined rules, providing an added layer of security and eliminating the need for intermediaries.
DeFi can provide faster and more efficient financial services. Traditional financial systems often involve multiple intermediaries, which can result in delays and higher costs. DeFi eliminates or minimizes the need for intermediaries, allowing for faster and direct peer-to-peer transactions. Moreover, DeFi platforms leverage smart contracts and automation, streamlining processes and reducing administrative overhead.
DeFi offers greater flexibility in terms of financial services and customization. DeFi protocols are open-source, meaning that developers can build and integrate their own applications and services on top of existing infrastructure. This flexibility allows for the creation of innovative financial products and services tailored to specific needs and preferences.
DeFi operates on blockchain technology, which is a decentralized digital ledger that records transactions in a secure and transparent manner. Blockchains use cryptographic algorithms to secure transactions and prevent tampering or fraud.
Smart contracts are self-executing computer programs that run on blockchain networks. Smart contracts enable DeFi protocols to automate financial transactions, such as lending, borrowing, trading, or insurance. Smart contracts can enforce the terms of a transaction without the need for intermediaries.
DApps are software applications that run on blockchain networks. dApps can provide a range of financial services, such as decentralized exchanges (DEXs), stablecoins, lending and borrowing platforms, insurance, or decentralized identity verification.
DAOs are organizations that operate on blockchain networks and are governed by smart contracts. DAOs can enable decentralized decision-making, funding, and management of projects. DAOs can also provide decentralized governance for DeFi protocols, enabling community-driven decision-making.
DEXs are decentralized platforms that enable peer-to-peer trading of cryptocurrencies without intermediaries. DEXs can provide greater privacy, security, and control than centralized exchanges, as users have sole control over their funds and can trade directly with each other.
Stablecoins are cryptocurrencies that are pegged to the value of a stable asset, such as the US dollar or gold. Stablecoins can provide a stable and predictable value for transactions, enabling greater adoption of cryptocurrencies as a medium of exchange or store of value.
DeFi lending and borrowing platforms enable users to lend or borrow cryptocurrencies without intermediaries. Lending and borrowing platforms can provide greater flexibility, lower interest rates, and faster processing times than traditional lending platforms.
DeFi insurance protocols enable users to buy or sell insurance coverage without intermediaries. DeFi insurance can provide greater transparency, lower fees, and faster payouts than traditional insurance companies.
DeFi protocols can enable decentralized identity verification, enabling users to prove their identity without intermediaries. Decentralized identity verification can provide greater privacy, security, and control than traditional identity verification methods.
DeFi protocols can be vulnerable to hacks, fraud, or exploits, as they operate in a decentralized and open environment. DeFi protocols can also be subject to smart contract bugs or vulnerabilities, which can be exploited by attackers.
DeFi operates in a regulatory grey area, as it is not subject to traditional financial regulations. Regulators may impose new regulations or restrictions on DeFi protocols, which could limit their adoption or growth.
DeFi protocols can suffer from liquidity issues, as they rely on a limited pool of users and assets. Low liquidity can limit the availability of financial services and increase the risk of market volatility or price manipulation.
DeFi protocols operate on different blockchain networks, which can limit their interoperability and scalability. Interoperability solutions, such as cross-chain bridges or layer-two protocols, are being developed to address these issues.
DeFi is expected to continue to grow in popularity and adoption, as more users and institutions recognize the benefits of decentralized finance. DeFi is also expected to integrate with traditional financial systems, enabling greater interoperability and collaboration.
DeFi is expected to continue to innovate and develop new use cases, such as decentralized prediction markets, tokenized real estate, or decentralized autonomous organizations (DAOs). These new use cases can expand the scope and impact of DeFi.
DeFi has the potential to achieve mass adoption, as it can provide financial services to anyone with an internet connection, regardless of their location or background. DeFi can also provide greater transparency, security, and efficiency than traditional financial systems, enabling greater trust and adoption.
DeFi is a growing industry that offers numerous benefits such as accessibility, transparency, security, efficiency, and flexibility. DeFi operates on blockchain technology and smart contracts, enabling decentralized financial services without intermediaries.
DeFi has the potential to revolutionize the financial industry, enabling greater democratization, innovation, and collaboration. DeFi also poses challenges such as security risks, regulatory challenges, liquidity, and interoperability. However, these challenges are being addressed by the DeFi community through innovation and development.
In summary, DeFi is an exciting and rapidly growing industry with enormous potential to disrupt traditional finance and enable greater financial inclusion and innovation. While there are challenges to be addressed, the benefits of DeFi are significant, and its future looks bright. As DeFi continues to evolve and develop, we can expect to see more innovative use cases and greater adoption by users and institutions alike.

The power of Fastex’s POSA consensus: Empowering validators and businesses alike – Cointelegraph
"Stakers and validators usually don't care about the blockchain platform they're using, they don't care about its health. We want to change that," said Pavel Aramyan, Blockchain Program Lead at Fastex and one of the guests at Cointelegraph's live. "We want to actually reward validators and businesses and encourage them to provide value to users."
And Fastex is doing that with its Proof-of-Stake-and-Activity (POSA) consensus mechanism, which was unveiled earlier this year on the Fastex Bahamut chain and was one of the main topics of Cointelegraph's recent AMA, among other Fastex projects.
"The differe nce between POSA and other consensus mechanisms is that it takes into account the activity of the gas usage of smart contracts," Aramyan said. "In simple terms, if you have a business that runs on smart contracts and is deployed on the Fastex chain, the more usage your business and application gets, the more blocks you'll propose and fees you'll generate from the network."
This means that by attaching smart contract addresses to validator addresses, companies on the Fastex chain can accumulate activity based on the gas usage of their smart contracts. This activity determines their chances of becoming a block producer and generating fees from the network.
This unique approach offers endless opportunities for businesses, with both traditional and decentralized services. Especially for Web2 businesses the transition to blockchain can be challenging due to the fear of losing control and valuable user data. But with POSA, a company can focus solely on the growth.
"There are endless possibilities for this activity blockchain parameter, and we think all consensus mechanisms should take this into account because it drives companies and smart contract creators to really think about their user base and the business they're building," Aramyan said.
Built as a fork of Ethereum 2.0, Fastex Chain inherited Ethereum's security and still undergoes continuous auditing processes. "When it comes to building smart contracts and dApps, the highest level of security and reliability is a priority for us. That's why we engage in a rigorous auditing process conducted by at least two independent auditors. Our preferred partners for these audits are renowned companies in this area like Certik and Hexens, ensuring the highest standards of security. We constantly strive to improve by updating and enhancing our systems on a regular basis," Aramyan said.
In addition to the blockchain platform, the Fastex ecosystem includes a wide range of other projects, as outlined by another AMA guest, Vardan Khachatryan, Chief Legal Officer at Fastex.
One of them is the next-generation payment technology Fastex Pay, which offers a comprehensive range of solutions, including crypto and fiat services, online and offline B2B and B2C payments, and integration with other crypto exchanges and companies. "We combine traditional payment systems with innovative blockchain-based technologies to provide a holistic suite of products for our users," said Khachatryan.
"We also have an NFT marketplace," he added. "And two offline NFT stores in Dubai Mall and Mall of the Emirates, which are quite popular. We realize that customers like the physical integration of NFTs, and artists work in different media. So we bring everyone together - NFT enthusiasts, NFT collectors, artists - to meet the evolving needs of our diverse community."
"At Fastex, our mission is to empower people to make the most of their assets by providing practical use cases for cryptocurrencies, not just our Fasttoken," said Aramyan. "We are actively working to educate and engage a broader audience on the benefits and risks of crypto. Our focus is on building a fast and effective system that instills confidence and simplifies this experience."

Introducing Managed dAPIs: Building Trust through Source Transparency – Yahoo Finance
DUBAI, United Arab Emirates - (NewMediaWire) - June 12, 2023 - (King NewsWire) - Today, API3 is thrilled to announce the launch of Managed dAPIs, a groundbreaking solution that revolutionises the way decentralised applications (dApps) interact with off-chain data. Managed dAPIs offer developers a secure, reliable, and scalable approach to accessing real-world data on-chain, while prioritising source transparency and trust.
In the rapidly evolving landscape of the Web3 data economy, the need for reliable and transparent connections between real-time market data and smart contracts has become paramount. Managed dAPIs, powered by API3, address these challenges by providing high-quality reference data served on-chain by first-party oracles. By eliminating third-party intermediaries and enhancing data integrity, Managed dAPIs establish a new standard for fostering trust through data source transparency andembody the core values of blockchain technology.
Key features of the Managed dAPIs
Managed dAPIs offer a wide range of features that not only ensure reliability and efficiency but also significantly improve security. These attributes make Managed dAPIs the ideal choice for dApps seeking accurate, reliable, and secure data in the rapidly changing oracle space.
1. First-Party OraclesManaged dAPIs utilise first-party oracles, enabling data to be served directly from reputable API providers via the API3 Airnode. This direct connection eliminates the need for third-party intermediaries, reducing the possibility of data manipulation or bias. The first-party oracle architecture fosters trust through source reputation and end-to-end transparency. Developers can verify the data source on-chain, providing confidence in the integrity and accuracy of the accessed data.
2. Multi-Source Data FeedsManaged dAPIs aggregate data from numerous first-party oracles, creating multi-source data feeds. This approach ensures a broad and diverse range of data points, contributing to the overall accuracy and reliability of the data. Each beacon or data point in a Managed dAPI represents a unique provider that is verifiable, ensuring data integrity and reducing potential bias.
Story continues
3. Push Oracle ArchitectureManaged dAPIs utilise a push oracle architecture, actively pushing data to the blockchain and making it readily available for dApps. This push architecture enhances efficiency and ensures timely data feed updates, benefiting both developers and end-users. Furthermore, this design makes it easy for dApps to migrate from existing oracle services.
4. Improved Security With Native-Chain AggregationTo provide maximum security, Managed dAPIs use native-chain aggregation, combining data on the same chain that the oracle is being used on. Native-chain aggregation maximises security by eliminating the need for bridges, which come with their own risks and vulnerabilities. With native-chain aggregation, developers can rely on a secure and reliable data feed. These features make Managed dAPIs a powerful solution for building better oracles in the DeFi ecosystem. By focusing on end-to-end transparency, high-quality data sources, efficient data delivery, and robust security, Managed dAPIs set a new standard for how dApps access real-world data on the blockchain.
Accessing Managed dAPIs
Managed dAPIs have been designed to be developer-friendly and easy to implement. They can be accessed via the API3 Market, providing developers with seamless access to aggregated data feeds. The market offers a range of multi-source dAPIs with various deviation thresholds and heartbeat specifications, allowing developers to choose a service that aligns with their unique requirements. While existing dAPIs are always free to read, the creation of a new multi-source feed requires the user or 'sponsor' to pay for the upgrade to create the data feed. Users are required to pay for the upgrade to a Managed dAPI in native chain currency, covering the operational expenses associated with gas costs. The sponsoring dApp essentially upgrades the service to a multi-source data feed, which API3 creates and maintains. Once established, the feed becomes accessible to all users, as long as the sponsoring dApp continues to fund the Managed dAPI. This flexible and scalable nature of the service accommodates changes to contracts during their term, providing additional scalability to developers.
Operational OversightThe API3 DAO dAPI team provides 24/7 monitoring of Managed dAPIs, ensuring continuous checks on wallets and API responses for reliability and security. The team can also update or "re-map" dAPIs to meet evolving requirements, ensuring a continuous improvement cycle. This level of operational oversight guarantees that Managed dAPIs maintains their integrity and reliability at all times.
Simple IntegrationManaged dAPIs have been designed for easy integration. Comprehensive documentation and guides are available to simplify the process, and a dedicated developer community provides technical support and best practices. Whether an individual is a seasoned developer or a newcomer, they will find the integration process of Managed dAPIs smooth and intuitive. Managed dAPIs are supported across 12 different networks, including Ethereum, Arbitrum, Polygon zkVM, and Optimism. Data feed contracts are adapted to the specific duration limits of each chain, ensuring compatibility. This multi-chain support expands the reach of Managed dAPIs, providing developers and blockchain networks with increased opportunities to harness the potential of decentralized data feeds.
Paving a Road to Better Protocol Performance with Oracle Extractable Value
As API3 progresses into the next phase of the dAPI rollout, API3 is turning the challenges posed by Maximal Extractable Value (MEV) into an opportunity to optimise the DeFi ecosystem. Traditionally, MEV has caused significant value loss for dApps and contributed to a poor user experience. API3 is addressing these challenges by designing a process to capture Oracle Extractable Value (OEV), a subset of MEV related to oracle updates. Outlined in the API3 OEV Litepaper, API3 will introduce an off-chain marketplace that allows dApps to auction off meta-transactions signed by first-party oracles for updating data feeds. Searchers bid for the right to perform these oracle updates, capturing the MEV associated with the transaction. This shared benefit model ensures that price feeds are updated according to the dApp's needs rather than solely relying on deviation thresholds, similar to a pull-based oracle. The transformative aspect of OEV lies in the fact that the value captured by searchers is shared with the dApps through the auction process. This approach minimises the negative impacts of MEV extraction, fostering the creation of accurate and low-latency oracles, which, in turn, enhance protocol performance and efficiency. One profound impact of OEV is its ability to create more accurate and low-latency oracles, increasing the profitability and sustainability of liquidity provision. This, in turn, improves market-making and attracts more liquidity to the application, fostering better performance and a superior user experience. By introducing a process to capture OEV, API3 demonstrates the power and potential of Managed dAPIs, paving the way for a sustainable and profitable future in DeFi.

Ox: A Protocol for Decentralized Exchange and Asset Tokenization … – Auralcrave
Decentralized finance (DeFi) is transforming the financial landscape by providing users with trustless, transparent, and permissionless financial services. Ethereum has been a major player in the DeFi ecosystem, offering a robust platform for decentralized applications (dApps) and smart contracts. The Ox protocol is one of the leading decentralized exchange (DEX) protocols on Ethereum, enabling asset tokenization and trading without the need for intermediaries. In this article, well dive into the Ox protocol and explore how it works, its benefits, and its potential use cases. Bitcoin can be the future and trading in it can be yours. Waiting for what? Start with the quantum-ai-trading.com now!
The Ox Protocol is a decentralized infrastructure built on top of the Ethereum blockchain that allows for the creation of decentralized exchanges (DEXs). DEXs are a new type of exchange where users can trade digital assets without having to rely on a central authority to hold their funds or execute trades. The Ox Protocol achieves this by utilizing smart contracts, which are self-executing computer programs that facilitate the exchange of assets on the blockchain.
One of the unique features of the Ox Protocol is its modular architecture, which allows developers to easily customize their DEXs and add additional features as needed. This enables developers to create DEXs that are tailored to specific use cases and user needs. The protocol has gained significant popularity in the blockchain industry, with a growing number of DEXs being built on top of the Ox Protocol, providing users with more options for trading their digital assets in a secure and decentralized manner.
The Ox Protocol is a decentralized infrastructure built on top of the Ethereum blockchain that enables the creation of decentralized exchanges (DEXs) without the need for a central authority. consists of several smart contracts that govern the behavior of the DEX, including the Exchange contract and the TokenRegistry contract. The Exchange contract manages the order book, while the TokenRegistry contract maintains a list of all ERC-20 tokens that can be traded on the DEX.
To trade a token on the DEX, a user must first approve the Exchange contract to spend their tokens. Once approved, the user can submit an order to the order book, where it will be matched with other orders based on price and quantity. When a trade is executed, the smart contract automatically transfers the tokens from the buyer to the seller and updates the order book accordingly. With the Ox Protocol and platforms like Bitcoin Era, users can enjoy the benefits of decentralized trading, including greater security, privacy, and control over their assets.
The Ox protocol offers several benefits over centralized exchanges and other DEXs. First and foremost, the Ox protocol is trustless, meaning that users do not need to trust a centralized third-party with their funds. This eliminates the risk of theft or loss due to exchange hacks or malfeasance. Additionally, the Ox protocol is transparent, allowing anyone to inspect the smart contracts and verify that the DEX is functioning as intended. The protocol also offers greater privacy, as users can trade without needing to disclose their identity or personal information. Finally, the Ox protocol is permissionless, meaning that anyone can participate in trading on the DEX without needing approval or permission from a centralized authority.
The Ox protocol has several potential use cases in addition to decentralized exchange. One of the most promising is asset tokenization. The protocol enables the creation of ERC-20 tokens that represent real-world assets, such as commodities, real estate, or stocks. These tokens can be traded on the DEX, providing greater liquidity and access to a wider range of investors. Additionally, the Ox protocol can be used to create prediction markets, decentralized lending platforms, and other financial services that are more transparent, efficient, and accessible than their centralized counterparts.
The Ox protocol is a powerful tool for enabling decentralized exchange and asset tokenization on the Ethereum blockchain. Its trustless, transparent, and permissionless design offers significant benefits over centralized exchanges and other DEXs. The protocols modular architecture allows developers to customize their DEXs and incorporate additional features as needed. With its potential for asset tokenization and other use cases, the Ox protocol is poised to play a major role in the future of decentralized finance.

Cryptocurrency exchange SaaS solutions can be centralized, decentralized and hybrid. Centralized exchanges are the most attended platforms: 10 billion USD daily trading volume on Binance. Decentralized and hybrid exchanges are gaining popularity: 800 million USD daily trading volume on dYdX. Today, in detail about centralized and decentralized exchanges, their strengths and weaknesses.
A centralized cryptocurrency exchange (CEX) allows exchanging, storing, buying, sending virtual assets.n CEXs have watchdogs that:
This scenario resembles traditional banks: a client opens an account, transacts money, stores it. The bank owns the money, not the client. The same is true for CEXs.
Examples of CEXs: Binance, Coinbase, Kraken, KuCoin, Bitfinex, Gemini, Coincheck, Bitstamp, Bybit.
CEXs are popular among investors because these platforms guarantee stability and security. Beginners also prefer centralized crypto exchanges as CEXs provide convenient interface and wide trading functionality. Other advantages of CEXs:
Centralized exchanges implement KYC and AML algorithms. KYC checks verify each client: their identity, country of residence. AML verification helps to detect fraudulent operations and eliminate them. These strategies protect users from risky transactions.
There are several liquidity providers that produce a high turnover on CEXs. Orders can be executed instantly. Good liquidity reduces slippage fees and high spreads. Plus, big liquidity retrench volatility and rate counterfeit.
CEXs are secured from fraudful projects. If an altcoin ends up on a centralized exchange, like Binance or Kraken, it means the coin passed strict checks. Plus, listing cost a considerable sum, starting from 5% of ICO.
Multi-stage protection is not always enough to secure crypto assets from hackers. Centralized cryptocurrency exchanges insure users. For that, clients pay a fee. Yet, these measures guarantee the safety of assets.
Centralized exchanges are popular and offer professional tools for trading. However, CEXs have several disadvantages:
KYC checks protect accounts and funds. That said, it is deanonymization too, which diverges from the anonymous nature of cryptocurrencies. Besides, there is a risk of personal data leaks.
Assets stored on a CEXs wallet belong to the platform. Clients can withdraw crypto to personal wallets. But the exchange may go bankrupt or get hacked before users transfer the money.
Hackers often break into CEXs hot wallets. Hackers can sneak into decentralized exchange wallets as well. With CEXs, however, clients are helpless. If a CEX is hacked, it is a problem of the CEX. Users lose their crypto anyway.
A decentralized cryptocurrency exchange (DEX) allows p2p trading. Traders send crypto directly to each other, without an intermediary. Most DEXs operate on the Ethereum blockchain because it has smart contracts, lines of code that enable execution if conditions are met. Smart contracts equip DEXs with algorithms that establish the price of crypto assets.
To assist transactions, investors place assets in liquidity pools. Liquidity pools provide liquidity to a DEX. While liquidity pools investors collect interests.
Examples of DEXs: Uniswap, Covo, SushiSwap, Pancake Swap, Curve Finance, dYdX.
Decentralized exchanges usually have a developer who works on smart contracts and elaborates protocols. Nevertheless, DEXs are more secure platforms since there is no central governor that can be tampered with. Other advantages of DEXs:
DEXs do not have order books that display information about placed orders. Clients transact cryptocurrencies directly. There is no margin trading, limit and market orders.
Traders can anonymously trade virtual assets. DEXs do not have KYC and AML checks. Besides, users do not need to provide personal data: passport ID, photo, country of residence.
Only clients can access their assets. Decentralized exchanges do not store users money. So, neither developers nor authorities can freeze funds or impose restrictions.
Transactions are based on blockchain and are triggered by smart contracts. Authorized entities cannot intrude on an operation. Nor can scammers.
Decentralized cryptocurrency exchanges rank below CEXs in the volume of trading. Total decentralization brings disadvantages:
DEXs allow users to trade tokens that belong to one blockchain network. Some sites introduce cross-chain bridges, which complicates an exchange process.
Transaction fees are higher on DEXs than on CEXs. Moreover, since transactions are carried out directly in the blockchain, a user pays the network commission. In protocols, like Ethereum or Bitcoin, the commission can reach dozens of dollars.
P2P trading can hardly be called a full-fledged exchange. There are no order books, no orders: sell stop, buy stop, sell limit, buy limit, etc. Such inventory deficiency can complicate trading and lead to losses.
The choice relies on a clients objective. Active traders will benefit more from a centralized exchange. They can save money on commissions, employ a wide trading inventory, such as margin trading, cryptocurrency futures, and complete deals quickly.
For long-term investors or traders with few trading transactions, DEXs work best. Assets remain in personal wallets without third parties accessing them. Venture investors can also profit from DEXs because they can reach emerging crypto assets right after the launch.
If anonymity plays a role, then DEXs again. This opportunity though will be closed: regulators are working on a legislative framework for decentralized exchanges to know their client.
