## ما هي Steem (STEEM)؟

إنّ Steem [سلسلة كتل](https://coinmarketcap.com/alexandria/glossary/blockchain) تُركز على المجتمع وتخلق فرصة كسب فورية لمستخدمي الشبكة. تم تصميم البروتوكول لتوفير فرصة ربح للعملاء بناءً على قيمتها بالنسبة للشبكة. كما أنه مصمم لتزويد المستخدمين بمنصة حيث يمكنهم نشر محتوى منظم عبر الإنترنت والحصول على أموال بالعملة المشفرة.

إنّ البروتوكول عبارة عن قاعدة بيانات محفزة ومتاحة للجمهور قائمة على سلسلة الكتل، تُتيح للمستخدمين التفاعل مع أنفسهم وتحقيق أرباح في المقابل. كما تستفيد من التقنيات من كل من وسائل التواصل الاجتماعي والعملات المشفرة لتزويد المستخدمين بقيمة. تضمن الشبكة المعاملة العادلة للمساهمين من خلال تشغيل هيكل مكافأة يعكس مساهمة كل مستخدم.

إنّ [Steemit](https://coinmarketcap.com/ar/currencies/steem/social/) هو أول تطبيق تم إنشاؤه على سلسلة كتل Steem، وتم إطلاقه في 4 يوليو 2016. يهدف البروتوكول إلى توفير قيمة لمجتمع المستخدمين بالطرق التالية:

* لتقديم الأخبار والشروحات المختارة بعناية.
* خلق فرصة للكسب.
* كمصدر يقدم إجابات على استفسارات المستخدمين.
* تقديم عملة مشفرة ثابتة مرتبطة بالدولار الأمريكي.

### من هم مُؤسسو Steem؟

أطلق نيد سكوت إلى جانب دان لاريمر، مطور سلسلة الكتل، أول تطبيق على سلسلة كتل Steem في يناير، يُسمى Steemit. يشبه التطبيق تطبيقات الشبكات الاجتماعية الأخرى باستثناء أنه يعتمد على تقنية سلسلة الكتل، مما يجعله تطبيقًا لامركزيًا وغير حافظ. إنّ الشبكة خالية من المشاكل الشائعة المتعلقة بالبيانات التي تواجهها المنصات الاجتماعية التقليدية.

عمل نيد سكوت كمحلل مالي للعمليات التجارية ومحلل مالي في شركة أمريكية لاستيراد الأغذية، Gellert Global Group، في فترة ما بين عام 2012 و عام 2015. التقى دان بشريكه في عام 2015 حيث اكتشف أن لديهم نفس الاهتمامات.

إنّ دان لاريمر مهندس برمجيات ورجل أعمال متسلسل مفتون بتقنية سلسلة الكتل ومنصات التداول اللامركزية (DEXs) والعملات المشفرة وغيرها من التقنيات. شارك دان في تأسيس شركة Steem جنبًا إلى جنب مع نيد سكوت، كما شغل منصب المدير التنفيذي للتكنولوجيا إلى أن ترك الشركة في عام 2017.

### ما الذي يميز Steem؟

حققت العديد من شركات وسائل التواصل الاجتماعي التقليدية الكثير من الأموال من خلال المحتوى الذي ينتجه مستخدموها. ومع ذلك ، فإن ما يميز Steem هو الدعم الذي يقدمه لمستخدميه من خلال مكافأتهم على مساهماتهم القيمة في النظام الأساسي.

تتمثل إحدى الميزات الفريدة للشبكة في أنها تعتمد على تقنية blockchain - مما يجعلها الأولى من نوعها. نتيجة لذلك ، فهي غير خاضعة للحراسة ولا مركزية ، ولا يوجد بها أي تعطل أو إساءة استخدام للبيانات ، كما أن بيانات المنصة مؤمنة تمامًا أيضًا. أيضًا ، يتم الدفع للمستخدمين بالعملات المشفرة مقابل المشاركة في النظام الأساسي.

يسترشد Steem بمبدأ أساسي واحد: أن أولئك الذين يساهمون في مشروع ما يجب أن يدفع لهم المالكون ، تمامًا كما تفعل الشركات الناشئة من خلال تخصيص الأسهم خلال جولات التمويل. هناك اعتقاد أساسي آخر هو خدمة أفراد المجتمع من خلال تقديم مختلف الخدمات والفرص المالية.

### كم عدد عملات Steem (STEEM) المُتداولة؟

على عكس سلاسل الكتل الأخرى حيث يتم إنشاء عملات جديدة من خلال التعدين، تُوزع Steem الجزء الأكبر من عملاتها (STEEM) إلى مُجمع المكافآت. إن STEEM العملة الرئيسية للبروتوكول. يوزع المُجمع الرموز للمستخدمين على النظام الأساسي بناءً على مدخلاتهم.

يضيف الشهود (حسابات إنشاء الكتل) كتلًا جديدة إلى سلسلة كتل Steem كل ثلاث ثوانٍ. وعليه يتم إنتاج STEEM بواسطة الشبكة يوميًا ويتم توزيع العملات الجديدة على النحو التالي:

* يتلقى القائمون على صناعة المحتوى والمؤلفون 75% من العملات الجديدة التي تم إنشاؤها.
* ويتم تخصيص 15% من العملات للمستخدمين الذين لديهم مقتنيات Steem Power (وهي عملة مشفرة أخرى من Steem).
* ويتم منح 10% المتبقية إلى الشهود.

إنّ العملات المشفرة الأخرى بخلاف STEEM هما [Steem Dollars (SBD)](https://coinmarketcap.com/ar/currencies/steem-dollars/) و Steem Power (SP).

### كيف يتم تأمين شبكة Steem؟

بعد أن اشترى جاستن صن، مؤسس منصة Tron، الشركة، تمت إعادة هيكلة عمليات Steem. وعليه لم يعد يتم إنشاء كتل جديدة من خلال التعدين ولا تستخدم الشبكة إثبات العمل.

لا يعتمد البروتوكول على [إثبات العمل](https://coinmarketcap.com/alexandria/article/proof-of-work-vs-proof-of-stake) لإنشاء كتل جديدة ولكنه يقوم بجدولة الشهود لإنشاء كتلة كل ثلاث ثوانٍ. ولكن سلسلة كتل Steem تستخدم إثبات الحصة المفوض لزيادة سرعة المعاملات على المنصة وجعلها أكثر قابلية للتوسع. ويتم مكافئة الشهود بـ Steem Power مقابل كل كتلة تم إنشاؤها.

### أين يُمكنك شراء Steem (STEEM)؟

هناك العديد من منصات تداول العملات المشفرة حيث يمكن للمستخدمين شراء رموز Steem أو SteemPower أو Steem Dollars (SBD)، أو حتى تحويلها إلى العملات المحلية. كما يمكن للمستخدم الذي ليس لديه حساب أن يشتري من خلال منصات تداول العملات المشفرة، على سبيل المثال، منصة [Binance](https://coinmarketcap.com/ar/exchanges/binance/). كما يمكن بسهولة تداول STEEM و Steem Dollars مقابل عملات bitcoin، والتي يمكن تحويلها بعد ذلك إلى عملات ورقية.

Hive (HIVE) is a blockchain running on a delegated proof-of-stake (DPoS) consensus mechanism. It launched in March 2020 as a hard fork of the centralized Steem blockchain and as a gateway from Web 2.0 to Web 3.0. The blockchain claims to offer “lightning-fast processing times and fee-less transactions.” Examples of use cases include social media with monetized rewards for content creators, interactive blockchain games, identity management, micro-loans and more. The platform powers decentralized applications (dApps) like Splinterlands, PeakD and HiveBlog.

Hive is a social network of apps and services, where users discover the capacity of blockchain technology, connect to the platform and securely share content through equitable redistribution of value. Thus, the users are the proprietors of the network, and sponsors can contact communities and artists directly without intermediaries.

Hive is an open source blockchain that focuses on scaling through layer-2 sidechains, while still benefiting from a common layer-1 blockchain backbone to ensure distributed data integrity. The Hive ecosystem runs on two cryptocurrencies — the native governance token, HIVE and the USD-pegged HBD stablecoin.

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.

BitShares Blockchain is a decentralized “Blockchain as Organization” (BaO); an industrial-grade decentralized open source platform built to run high-performance financial technology operations. It represents the first decentralized autonomous decentralized community that enables its core utility token (BTS) holders to decide the Blockchain future direction in order to develop and maintain a wide range of decentralized financial technology products, features and functions. BitShares Blockchain is a Blockchain that permanently records financial technology operations between different Blockchain accounts and facilitates a wide range of access controls across BitShares Blockchain user financial means.

BitShares Blockchain is a technology that supports the digital generation entrepreneurs, investors, and developers with a common interest in building and participating in free market solutions by leveraging the power of globally decentralized consensus and decision making. Consensus technology has the power to do for economics what the internet did for information. It can harness the combined power of all humanity to coordinate the discovery and aggregation of real-time knowledge, previously unobtainable. This knowledge can be used to more effectively coordinate the allocation of resources toward their most productive and valuable use.

BitShares looks to extend the innovation of the Blockchain to all industries that rely upon the internet to provide their services. Whether its banking, stock exchanges, lotteries, voting, music, auctions or many others, a digital public ledger allows for the creation of distributed autonomous companies (or BaO) that provide better quality services at a fraction of the cost incurred by their more traditional, centralized counterparts. The advent of (BaO) ushers in a new paradigm in organizational structure in which companies can run without any human management and under the control of an incorruptible set of business rules. These rules are encoded in publicly auditable open source software distributed across the computers of the companies’ shareholders, who effortlessly secure the company from arbitrary control. BitShares does for business what bitcoin did for money by utilizing distributed consensus technology to create companies that are inherently global, transparent, trustworthy, efficient and most importantly profitable.

BitShares has went through many changes and has done its best to stay on top of Blockchain technology. BitShares is using Consensus as the mechanism by which organized people decide upon unitary rational action. While not considered technology in the traditional since, consensus “technology” is the basis of democratic governance and the coordination of free market activity first coined by Adam Smith as the “Invisible Hand.” The process of consensus decision-making allows for all participants to consent upon a resolution of action even if not the favored course of action for each individual participant. Bitcoin was the first system to integrate a fully decentralized consensus method with the modern technology of the internet and peer-to-peer networks in order to more efficiently facilitate the transfer of value through electronic communication. The proof-of-work structure that secures and maintains the Bitcoin network is one manner of organizing individuals who do not necessarily trust one another to act in the best interest of all participants of the network. The BitShares ecosystem employs Delegated Proof of Stake in order to find efficient solutions to distributed consensus decision making.

Civic is a blockchain-based identity management solution that gives individuals and businesses the tools they need to control and protect personal identity information.

The platform is designed to change the way we think about identity verification by giving users more control over their personal data, while allowing them to access a wide range of services without needing to fork over excessive amounts of personal information.

Civic's identity verification solution uses distributed ledger technology to authorize identity usage in real time, and is used to sparingly share information with Civic partners after authorization by the user.

Unlike some other identity management services, Civic users store all their sensitive data on their mobile device. Users are able to authorize the sharing of specific personal data by providing a biometric signature through the Civic app.

The Civic ecosystem is enabled by a unique utility token known as the Civic token (CVC), which is used for the settlement of identity-related transactions between Civic participants — such as between a customer and service provider.

Users can earn CVC tokens for completing a variety of tasks, such as signing up for a service through the platform or introducing new users, while validators can earn CVCs for validating documents for service providers.

Civic was launched in 2018, following a sell-out initial coin offering (ICO) the year prior.

Bancor is an ecosystem of decentralized, open-source protocols that promote on-chain trading and liquidity.

Its main protocol, Carbon, is a decentralized trading protocol allowing users to perform automated trading strategies using custom on-chain limit orders and range orders, with the option of combining orders together to create automated buy low, sell high strategies.

By design, Carbon orders are irreversible on execution, easily adjustable directly on-chain, and resistant to MEV sandwich attacks. These capabilities give users an unprecedented level of control and automation to perform novel trading strategies on-chain.

Fast Lane, a separate open-source arbitrage protocol, allows any user to perform arbitrage between Bancor ecosystem protocols and external on-chain exchanges and redirect arbitrage profits back to the Bancor ecosystem.

All Bancor ecosystem protocols are governed by the BancorDAO via staked BNT.

Loom Network is a platform as a service that is built on top of Ethereum and allows developers to run large-scale decentralized applications. This platform was released on October 1st, 2017.

The goal of this is to allow application developers to have smart contracts that can access much more computing power when it is required, or maintain the same power at lower costs for tasks such as trials for onboarding new users or applications that simply do not need the full security of blockchain to begin with.

In this system you have the ability to interact with APIs developed by third parties which are not on chain. Loom attempts to be the ultimate platform that allows smart contract developers to create applications without the need to switch to another programming language.

As such, they can easily integrate their applications with the outside world.

The Loom Network runs on Plasma, which is a scaling solution that allows for faster transactions throughout the network.
