## ما هو DigiByte (DGB)؟

إنّ DigiByte (DGB) عبارة عن سلسلة كتل مفتوحة المصدر ومنصة لإنشاء الأصول. بدأ التطوير في أكتوبر 2013 وتم تعدين كتلة التكوين الخاصة برمز (DGB) في يناير 2014 كفرع (Fork) منقسم من سلسلة كتل بيتكوين (BTC).

تستخدم DigiByte، وهي سلسلة كتل عامة وعملات مُشفرة، خمس خوارزميات مختلفة لتحسين الأمان، كما تهدف في الأصل إلى تحسين أمان سلسلة كتل بيتكوين وقدرتها وسرعة معاملاتها.

يتكون DigiByte من ثلاث طبقات: العقد الذكي "متجر التطبيقات" ودفتر الأستاذ العام والبروتوكول الأساسي الذي يتميز بالعُقد التي تتواصل لتتناوب المعاملات.

### من هم مؤسسو DigiByte؟

تم إنشاء DigiByte بواسطة جاريد تيت، المعروف أيضًا باسم "DigiMan"، والذي أشرف على تحولها من التطوير إلى الإعداد الحالي قبل أن يُعلن عن تقاعده مؤقتًا من منصبه في مايو 2020.

عاد تيت منذ ذلك الحين، واعتبارًا من سبتمبر 2020 ظهر مرةً أخرى مشاركًا بشكلٍ وثيق في نمو DigiByte.

تُشير سيرة تيت إلى أنه كان مشاركًا مع بيتكوين من عام 2012 فصاعدًا، وكان أول مؤسس سلسلة كتل يُؤلف كتايًا بعنوان "Blockchain 2035: The Digital DNA of Internet 3.0".

لا تعتمد عمليات DigiByte على المطورين فحسب، بل وتعتمد أيضًا على مؤسسة DigiByte، وهي مُنظمة تطوعية مكلفة بالإشراف على الحفاظ على المشروع. كما أنّ مجموعة ثالثة من المتطوعين، أو ما يُعرف باسم فريق DigiByte Awareness، مسؤولة عن أنشطة التسويق والترويج.

### ما الذي يُميز DigiByte؟

إنّ DigiByte هو تعديل لبيتكوين، يهدف إلى تنويع إمكانيات الأمان والسرعة والسعة.

كان تجسيدها الأول عبارة عن سلسلة كتل مفتوحة المصدر وعملة مُشفرة مرتبطة بها (DGB). تحتوي الشبكة على خمس خوارزميات منفصلة تُساعد في الحفاظ على الأمن وتساعد على منع مُعدني الدوائر المتكاملة محددة التطبيقات (ASIC) من الاستيلاء على الكثير من الطاقة.

وفي وقت لاحق، ظهر عرض آخر، وهو أصول ديجي (DigiAssets)، مع DGB كرمزها الأصلي. تُناشد أصول ديجي (DigiAssets) هؤلاء المطورين الذين يتطلعون إلى إطلاق الأصول الرقمية والتطبيقات اللامركزية (DApps) وترميز العقود الذكية المقابلة اللازمة.

يتم تشغيل جميع هياكل الحوكمة الخاصة بـ DigiByte على أساس طوعي، بما يتماشى مع فرضية أنّ الشبكة يجب أن تكون مفتوحة المصدر ومتاحة للجمهور. يتم دفع رسوم المعاملات بـ DGB للمُعدنين للتحقق من سلسلة الكتل.

### كم عدد عملات DigiByte (DGB) المُتداولة؟

إنّ DigiByte (DGB) عملة مُشفرة تسند إلى آلية إثبات العمل (PoW)، ويكسب المُعدنون رموزًا للتحقق من صحة الكُتل من خلال مكافآت الكتلة.

في يناير 2014، كان 0.5% من إجمالي المعروض من DGB (105 مليون عملة) قد تم تعدينه مسبقًا. تم حجز 50% من المُعدنة مسبقًا لأغراض التطوير، بينما تم توزيع الباقي.

لدى DGB حد أقصى للإمداد الثابت يبلغ 21 مليار رمز، حيث يشكل التعدين منحنى انبعاث مع انخفاض الإصدار — كما تقل مكافأة الكتلة بنسبة 1% كل شهر.

صرحت DigiByte بأنها لم تحاول عن عمد جمع الأموال أو التخلي عن الرموز من خلال أدوات مثل عرض العملة الأولي (ICO) أو بيع رموز مُشابه.

### كيف يتم تأمين شبكة DigiByte؟

تستخدم DigiByte ما مجموعه خمس خوارزميات إثبات العمل لتأمين سلسلة الكتل وتقليل مخاطر الإنفاق المُزدوج أو هجمات 51%.

تضمن تعديلات الصعوبة القدرة على الصمود ضد التحركات العدائية داخل دوائر التعدين، حيث تدعي DigiByte أنها تتمتع بإعدادات الصعوبة الأكثر تقدمًا بين العملات المشفرة.

مع كتلة واحدة تقريبًا كل 15 ثانية، تمكنت سلسلة كتل DigiByte من إثبات طول عمر سلسلة كتل آلية إثبات العمل (PoW) منذ إطلاقها، حيث تمتلك الآن سلسلة إثبات عمل (PoW) أطول بكثير من بيتكوين على سبيل المثال.

### أين يُمكنك شراء DigiByte (DGB)؟

إنّ DGB عبارة عن عملة بديلة قابلة للتداول بحرية ومتاحة في منصات تداول متعددة. تتوفر أزواج التداول لكل من العملات المشفرة والعملات المستقرة والعملات الورقية.

كان لكلٍ من Bilaxy و Binance و Sistemkoin و OKEx نصيب الأسد من حجم أزواج تداول DGB اعتبارًا من سبتمبر 2020.

Siacoin (SC) is the native utility token of Sia, a blockchain-based distributed, decentralized cloud storage platform. Sia acts as a secure, trustless marketplace for cloud storage in which users can lease access to their unused storage space. Agreements and transactions are enforced with smart contracts, and Siacoin is the medium of exchange for paying for storage on the network. The main goal of the project is to become the "backbone storage layer of the internet."

Sia was originally announced in May 2014 before being revised and re-announced a year later in May 2015. It officially launched in June 2015.

Holo is a peer-to-peer distributed platform for hosting decentralized applications built using Holochain, a framework for developing DApps that does not require the use of blockchain technology. The goal of Holo is to serve as a bridge between the broader internet and apps built using Holochain, offering an ecosystem and marketplace in which DApps are easily accessible, as they are hosted on the internet by Holo network participants.

The Holo network will be facilitated using a token called HoloFuel, which is actively being tested and will act as an accounting system to pay hosts for their services. In 2018, the project minted an ERC-20 token, HOT — also known as HoloToken — as an "IOU" that will be redeemable for HoloFuel upon launch.

Holo is still in development and is expected to launch for open alpha and beta testing by 2021.

NEM is a blockchain platform that was launched in March of 2015. It was one of the pioneers of the cryptocurrency industry, and sought to improve on the imperfections found on other chains at the time. It was one of the first non-turing complete chains to feature user-defined tokens (called mosaics), namespaces, multisignature accounts, and a P2P reputation system based on EigenTrust++. Its most notable contribution to the space is the proof-of-importance consensus mechanism, which sought to reward on-chain activity and deter the concentration of wealth commonly associated with proof-of-stake. Its client, NIS, is written in Java.

NEM has a global community. It sees the most utility as an alternative form of payment for businesses and vendors, and has a variety of social media apps built on top of it in Japan, such as nemgraph, a community-driven owned and operated alternative to Instagram.

In December 2021, NEM was hard forked by a pseudonymous team of cryptocurrency experts and enthusiasts alike. Titled Harlock, this hard fork signaled the community’s intent to take NEM from a shadow of its former self into the world’s leading payments platform for on-chain and off-chain media content.

Verge is a privacy-focused cryptocurrency and blockchain that seeks to offer a fast, efficient, decentralized payments network that improves upon the original Bitcoin (BTC) blockchain. It includes additional privacy features including integrating the anonymity network Tor into its wallet, called vergePay, and providing the option of sending transactions to stealth addresses.

The project describes itself as community-driven, relying on volunteers and priding itself on being open source.

Verge was first launched in October 2014 as DogeCoinDark, a fork of Peercoin (PPC). In February 2016, it was renamed Verge in order to rebrand for easier mass-market adoption and to distinguish itself from Dogecoin (DOGE), with which it has no direct connection. The project is now based on the Bitcoin source code.

Ontology is a project designed to bring trust, privacy, and security to Web3 through decentralized identity and data solutions. It is building the infrastructure to provide trusted access to Web3, allowing individuals and enterprises to rest assured that through regulatory compliant digital identity solutions, users and their privacy come first.

The Ontology blockchain is a high speed, low cost public blockchain. It is designed to bring decentralized identity and data solutions to Web3, with the goal of increasing privacy, transparency, and trust. To achieve this, users and enterprises are provided with the flexibility to build blockchain-based solutions that suit their needs, while also ensuring regulatory compliance. Through Ontology’s Ethereum Virtual Machine (EVM), Ontology ensures frictionless compatibility with Ethereum, the first step in the creation of the Ontology Multi-Virtual Machine and further interoperability for the chain.

At its launch, Ontology chose to forego the popular initial coin offering (ICO) model in favor of a series of community distributions and airdrops of its ONT cryptocurrency.

This helped to quickly establish both organic price discovery and a passionate community and helped the project to avoid subsequent regulatory scrutiny.

For example, for a brief period any person who signed up for the Ontology newsletter received an airdrop of free 1,000 ONT, which reached a value of $10 per token soon after the token became listed on major exchanges like Binance.

Ontology launched its own MainNet on June 30, 2018 and has been up and running smoothly since.

Basic Attention Token, or BAT, is the token that powers a new blockchain-based digital advertising platform designed to fairly reward users for their attention, while providing advertisers with a better return on their ad spend.

To learn more about this project, check out our deep dive of Basic Attention Token.

This experience is delivered through the Brave Browser, where users can watch privacy-preserving adverts and receive BAT rewards for doing so. On the other hand, advertisers can deliver targeted ads to maximize engagement and cut down losses due to ad fraud and abuse.

The Basic Attention Token itself is the unit of reward in this advertising ecosystem, and is exchanged between advertisers, publishers and users. Advertisers pay for their advertising campaigns in BAT tokens. Out of this budget, a small portion is distributed to advertisers, while 70% is distributed to users — whereas the intermediaries that typically drive up advertising costs are cut out of the equation to improve cost-efficiency.

Basic Attention Token launched in 2017 following one of the fastest sell-out initial coin offerings (ICOs) of all time, with the platform raising a total of $35 million in under a minute. Since then, it has rolled out its attention-based advertising experience to users in most countries through its Brave Rewards program.

As of November 2020, the United States, the United Kingdom and Canada had the most active advertising campaigns.

Qtum (pronounced ‘“quantum”)  is a proof-of-stake (PoS) smart contract open-source blockchain platform and value transfer protocol. It aims to bring together the strengths of Bitcoinand Ethereumin one chain. Qtum is built on Bitcoin's UTXO transaction model, with the added functionality of smart contract execution and DApps. Recently, the platform added support for DeFi applications. As of March 2021, there are more than 20 tokens created on the Qtum blockchain.

To learn more about this project, check out our deep dive of Qtum.

The project was announced in March 2016 and held an ICO a year after, in March 2017, which brought its founders $15 million USD. The Qtum main chain was released on Sept.13, 2017. Initially, the Qtum coin was issued as a ETH-20 token, but with the launch of the mainnet, it was converted to native blockchain.

Billed as "digital money for the modern world," nano is a lightweight cryptocurrency that is designed to facilitate secure, practically instant payments, without fees, and addresses some of the major limitations of both legacy financial infrastructure, and many modern cryptocurrencies.

Development of the project began in 2014 under the name RaiBlocks, and the coin (then termed XRB) launched the following year through a public faucet, which allowed users to claim small amounts of XRB after completing a captcha challenge. Anyone with access to a computer or phone could solve captchas, and be rewarded with RaiBlocks. The number of XRB people received per solved captcha varied over time

RaiBlocks (XRB) was rebranded to Nano in January 2018, with the new name chosen to better represent the speed and simplicity the project offers to users.

It is a peer-to-peer platform that uses a unique block-lattice data structure to allow users to easily transfer value to one another without relying on centralized intermediaries.

Unlike other platforms which typically use the combined proof-of-work of a massive mining network to achieve consensus, nano instead uses a system known as Open Representative Voting (ORV) — which sees account holders vote for their chosen representative, who then work to confirm blocks of transactions securely.

ORV makes Nano extremely energy efficient, positioning it as a more environmentally friendly alternative to proof-of-work (POW)-based cryptocurrencies.

In November, 2021, aiming to bring nano to the real world and to comply with the globally-recognized standards of the International Organisation for Standardisation (ISO) requirements, nano adopted a new ticker and a standard symbol: XNO and Ӿ.

Stellar (XLM) is a peer-to-peer (P2P) decentralized network created in 2014 by The Stellar Development Foundation or Stellar.org. The network officially launched in 2015 with the purpose of connecting the world's financial systems and ensuring a protocol for payment providers and financial institutions. The platform is designed to move financial resources swiftly and reliably at minimal cost. Stellar links people, banks, payment processors and allows users to create, send and trade multiple types of crypto.

The basis of the network is its native digital currency - XLM or Lumens. XLM acts as an intermediate currency for operations and is also used to pay transaction fees. How it works: the protocol converts money in a few seconds, first into XLM, and then into the requested currency.

The Stellar payment protocol is based on distributed ledger technology -- an open-source development, community-owned and distributed by community. The crypto asset of the Stellar platform helps with cross-border transactions, overcoming the problems of high fees and slow procedures. XLM is more focused on assisting individuals transfer money than they are with institutions. Thus, Stellar offers access to financial systems, and people can send money at low cost and promptly around the world.

Moreover, Stellar serves as a decentralized exchange and marketplace, with a built-in order book that tracks ownership of Stellar assets. Platform users can manage buy/sell orders, as well as select and set their preferred assets in settlements. XLM is a built-in coin that helps reduce transaction fees.

The network maintains a high level of security.  XLM holders must have at least one token in order to remain active on the network. This nuance performs a global goal - the execution of network transactions efficiently and with minimal time costs. Plus, Lumens offers protection against flood attacks by making microtransactions too expensive for hackers with no chance of profit, which keeps Stellar Network safe from serious threats.

The target audience of Stellar is the inhabitants of developing countries, ordinary users who are provided access to the global economy through fast, simple and inexpensive transactions. Stellar Network makes extensive use of Lumens to produce live convection as well as to send cash in multiple currencies; currency is sent from one peer, and the recipient can receive the amount in another currency. This feature is beneficial when a transaction is made between currencies without widely traded pairs.

Support for multi-currency transactions is another competitive advantage of Stellar, and the ability for cross-currency transactions has only enhanced processes with foreign operations. Moreover, stable speed and low transaction costs are a privilege that users receive.

This functionality is powered by a development called Anchors (a bridge between different currencies and the network), which simplifies the exchange within the network and helps speed up the whole process.

In summary, the benefits of Stellar (XLM) include:
