## ما هي Nano (NANO)؟

إنّ Nano عملة مشفرة خفيفة الوزن مصممة لتسهيل عمليات الدفع الآمنة والفورية عمليًا، بدون رسوم، وصفت بأنها "نقود رقمية للعالم الحديث"، حيث تعالج بعض القيود الرئيسية لكل من البنية التحتية المالية القديمة والعديد من العملات المشفرة الحديثة.

بدأ تطوير المشروع في عام 2014 تحت اسم RaiBlocks، وتم إطلاق العملة (التي كانت تسمى آنذاك XRB) في العام التالي من خلال صنبور (faucet) عام، مما سمح للمستخدمين بالمطالبة بكميات صغيرة من XRB بعد الانتهاء من اختبار captcha. تم السماح للمستخدمين بإكمال أكبر عدد ممكن من رموز التحقق (captcha) كما يرغبون — لتداول وقتهم وجهدهم بشكلٍ فعال مع XRB.

تم تغيير اسم RaiBlocks (XRB) إلى Nano (NANO) في يناير 2018، حيث يُمثل الاسم الجديد السرعة والبساطة التي يوفرها المشروع للمستخدمين بشكلٍ أفضل.

إنها منصة ند لند تستخدم بنية بيانات كتلة فريدة للسماح للمستخدمين بنقل القيمة بسهولة إلى بعضهم البعض دون الاعتماد على الوسطاء المركزيين.

وعلى عكس الأنظمة الأساسية الأخرى التي تستخدم عادةً إثبات العمل المشترك لشبكة تعدين ضخمة لتحقيق الإجماع، تستخدم Nano نظامًا يُعرف باسم تصويت الممثل المفتوح (ORV) — والذي يمنح أصحاب الحسابات حق التصويت لممثلهم المختار، والذين يعمل بعد ذلك على تأكيد كتل المعاملات بشكلٍ آمن.

يجعل نظام ORV شبكة Nano فعالة للغاية في استخدام الطاقة، مما يجعلها بديلاً أكثر صداقة للبيئة [للعملات المشفرة](https://coinmarketcap.com/alexandria/article/what-are-cryptocurrencies) القائمة على [إثبات العمل](https://coinmarketcap.com/alexandria/article/proof-of-work-vs-proof-of-stake) (POW).

### من هم مُؤسسو Nano؟

تم تأسيس Nano بواسطة كولين ليماهيو، مطور ومهندس برمجيات ذو خبرة كبيرة في العمل لشركات التكنولوجيا البارزة، بما في ذلك Dell و AMD و Qualcomm.

يصف ليماهيو نفسه بأنه مخترع، حيث تتراوح اهتماماته من تكنولوجيا الفضاء إلى الفيزياء والاستدامة البيئية، وهو موضوع شائع في مجال العملات الرقمية. بدأ ليماهيو العمل بدوام كامل في Nano في عام 2017 ولا يزال الرئيس التنفيذي لمؤسسة Nano — وهي منظمة تم إنشاؤها لقيادة تطوير وتبني Nano — إلى يومنا هذا.

ساهم كولين ليماهيو أيضًا في إضافة الغالبية العظمى من الالتزامات إلى مستودع Nano's في GitHub.

فضلاً ع ليماهيو ، تضم مؤسسة Nano أكثر من عشرة موظفين آخرين، بما في ذلك جورج كوكسون، خريج الأنثروبولوجيا التطورية ومدير حسابات ذو خبرة، ويشغل منصب رئيس العمليات الحالي للمؤسسة.

### ما الذي يُميز Nano؟

فكما تطرقنا سابقًا، تم تصميم Nano لتكون سريعة. إنها سريعة إلى درجة تصل فيها معظم معاملات Nano إلى نهائية مطلقة في أقل من ثانية — مقارنة بعدة دقائق أو حتى أطول للعديد من العملات المشفرة الرئيسية الأخرى.

تجعل هذه السرعة Nano مناسبةً للدفعات التجارية، فلن يقلق التجار وتجار التجزئة بعد الآن بشأن تأخير المعاملات عند قبول المدفوعات.

كما أن معاملات Nano مجانية. ونظرًا لأن الممثلين لا يتلقون تعويضًا ماليًا عن جهودهم لتأمين الشبكة، فلا داعي لدفع رسوم المعاملات. مما يجعل Nano حلاً مثاليًا لمعالجة المعاملات الصغيرة، فلن يقلق المستخدمون بعد الآن بشأن مواجهة رسوم معاملات باهظة الثمن عند إجراء مدفوعات صغيرة.

تُتيح هندسة المشروع الفريدة هذه الخصائص. على عكس العديد من العملات المشفرة التي يتم إنشاؤها فوق دفتر الأستاذ الموزع المعروف [بسلسلة الكتل](https://coinmarketcap.com/alexandria/glossary/blockchain)، تم بناء Nano حول تقنية دفتر الأستاذ المماثلة والتي تُسمى الرسم البياني غير الدوري الموجه (DAG).

إنّ هذا الهيكل موثوق للغاية حيث يسمح لشبكة Nano بمعالجة ما يصل إلى 1000 معاملة في الثانية (tps) — دون الحاجة إلى شبكة تعدين كثيفة الطاقة للحفاظ على سلامتها، الأمر الذي يجعل Nano خيار دفع رقمي صديق للبيئة.

### كم عدد عملات Nano (NANO) المتداولة؟

مثل الغالبية العظمى من العملات المشفرة، تمتلك Nano حدًا أقصى ثابتًا لعدد الرموز التي سيتم إنتاجها، حيث تم تعيين هذا الرقم بالضبط عند 133,248,290 رمز NANO.

تم تعيين العرض الأقصى الأصلي للإمداد أعلى بكثير من هذا، ولكن تم حرق أي رموز NANO متبقية أعلى من الحد الحالي الدائم والبالغ 133 مليون. إجمالاً، تم توزيع ما يقارب 39% من العرض الأولي.

كون العرض الكلي لشبكة Nano قيد التداول أمر غير معتاد، الأمر الذي يعني أن العرض تم تخفيفه بالكامل.

ونظرًا لكونها مخففة بالكامل، فإن Nano لها طبيعة لامركزية للغاية وموزعة بشكل جيد، حيث تمتلك الغالبية العظمى من حسابات Nano أقل من 100 رمز NANO. اعتبارًا من ديسمبر 2020، يتم الاحتفاظ بحوالي 20% من جميع رموز Nano المتداولة (حوالي 26 مليونًا) في إحدى المحافظ الباردة المرتبطة بمنصة تداول العملات المشفرة Binance.

تم حجز ما مجموعه 5% من العرض المتداول من أجل التطوير المستمر للمشروع، وقد تم تخصيص ذلك لما يسمى "صندوق المطور".

### كيف يتم تأمين شبكة Nano؟

يتم تأمين Nano من خلال شبكة من الممثلين، يتم التصويت على كل منهم من قبل حاملي رموز NANO.

هؤلاء الممثلون مسؤولون عن الإدلاء بأصواتهم عندما تحتاج الشبكة إلى تحقيق [الإجماع](https://coinmarketcap.com/alexandria/glossary/consensus)، وتكون قوتهم التصويتية هي مجموع وزن التصويت المفوض لهم من قبل حاملي NANO. حيث يقوم هؤلاء بالتصويت على صحة المعاملات على شبكة Nano، مما يضمن تأكيد المعاملات الصالحة فقط.

تحمي هذه العملية الشبكة من هجوم يُعرف بالإنفاق المزدوج — والذي يحدث عندما يكون المهاجم قادرًا على التلاعب بالشبكة لإنفاق نفس الأموال بشكل فعال مرتين.

إضافة إلى ذلك، تتميز شبكة Nano بمجموعة واسعة من الدفاعات الإضافية ضد مختلف الهجمات المحتملة — لإيجاد نظرة شاملة بهذا الخصوص من [هنا](https://docs.nano.org/protocol-design/attack-vectors/).

### أين يُمكنك شراء Nano (NANO)؟

ولأنه لا يمكن تعدين Nano، فإن الطريقة الأكثر شيوعًا للحصول عليها هي شرائها من أكثر من 50 منصة تداول تدعمها. إنّ [Binance](https://coinmarketcap.com/ar/exchanges/binance/) و [OKEx](https://coinmarketcap.com/ar/exchanges/okex/) و [Huobi Global](https://coinmarketcap.com/ar/exchanges/huobi-global/) من أكثر منصات التداول شيوعًا حاليًا بالنسبة لأزواج تداول العملات المشفرة و Nano، في حين يمكن أيضًا شراؤها باستخدام العملات الورقية على Kraken و Binance.US.

The Nano Foundation is a not-for-profit organization and encourages the growth and usability of nano, an instant, sustainable currency without fees.

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.

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.

OMG Network, formerly known as OmiseGo, is a non-custodial, layer-2 scaling solution built for the Ethereum blockchain. As an Ethereum scaling solution, OMG Network is designed to allow users to transfer ETH and ERC20 tokens significantly faster and cheaper than when transacting directly on the Ethereum network.

The network is based on a novel scaling solution called MoreViable Plasma, which uses a sidechain architecture to group several transactions off-chain into a batch, which can then be verified as a single transaction on the Ethereum root chain. According to OMG Network, this technology has the potential to scale Ethereum to thousands of transactions per second (TPS) — instead of the 10 to 14 tps Ethereum 1.0 is currently capable of.

The network is powered by the OMG utility token, which can be used as one of the payment methods for fees on the OMG Network, and will eventually be stakable — helping to secure the network in return for rewards.

Tezos is a high-performing blockchain and open-source platform for assets and applications, with a strong focus on code security, on-chain governance, and decentralization. Tezos 2.0, the upcoming step in the evolution of Tezos, aims to improve scalability (via layer 2s), composability, and to implement support to mainstream programming languages (like Javascript, Typescript, Python, and many others).

Initially built with formal verification in mind, the Tezos protocol enables builders to avoid bugs when developing smart contracts, making it particularly suited to applications that require a high degree of security and certainty.

Tezos’ LPoS (Liquid Proof-of-Stake) consensus mechanism enables any stakeholder to take part, directly or by delegation, in the consensus process, and to be rewarded for securing the network. Rather uniquely, Tezos’ on-chain governance system also enables stakeholders to create and vote on protocol upgrade proposals. This pioneering system allows the protocol to self-amend and upgrade itself without leading to a split (or fork) in the blockchain, empowering the community without slowing down innovation.

First proposed in 2014 and launched in 2018, the Tezos Mainnet has a proven track record of running uninterrupted ever since, having earned a strong reputation for technical excellence and a supportive community.

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.

Basic Attention Token

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.

Siacoin

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.

Ren (REN) is an open protocol built to provide interoperability and liquidity between different blockchain platforms.

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

Formerly known as Republic Protocol, Ren launched RenVM, its virtual machine mainnet, in May 2020, having completed a $34 million initial coin offering (ICO) in 2018.

The protocol’s native token, REN, functions as a bond for those running nodes which power RenVM, known as Darknodes.

Ren aims to expand the interoperability, and hence accessibility, of decentralized finance (DeFi) by removing hurdles involved in liquidity between blockchains.

Dash is an open-source blockchain and cryptocurrency focused on offering a fast, cheap global payments network that is decentralized in nature. According to the project's white paper, Dash seeks to improve upon Bitcoin (BTC) by providing stronger privacy and faster transactions.
