## Hedera Hashgraph (HBAR) کیا ہے؟

"انٹرنیٹ کی ٹرسٹ لیئر" کے طور پر پروگرام میں شامل کیا جانے والا Hedera Hashgraph ایک عوامی نیٹ-ورک ہے جو افراد اور کاروباری اداروں کو طاقتور غیر مرکزی ایپلیکیشنز ([DApps](https://coinmarketcap.com/alexandria/glossary/decentralized-applications-dapps)) بنانے کی استعداد دیتا ہے۔

یہ ایک بہتر، زیادہ موثر نظام بن جانے کے لیے ڈیزائن کیا گیا ہے جو کسی حد تک اُس محدودیت کا خاتمہ کرتا ہے، جس کا سامنا پرانے بلاک چین پر قائم پلیٹ فارمز کو کرنا پڑتا ہے — جیسے سُست کارکردگی اور عدم استحکام۔

اگست سن 2018 میں، اس کو بذریعہ ابتدائی-کوائن-پیشکش (ICO) مالی اعانت فراہم کی گئی، اور ایک سال بعد یعنی ستمبر سن 2019 میں پہلی بار اس کے مین-نیٹ تک آزادانہ رسائی کا آغاز ہوا۔ ICO کے ایک حصے کی حیثیت سے، سرمایہ کار پلیٹ فارم کے مقامی یوٹیلیٹی ٹوکن (HBAR) کو کم سے کم ممکنہ قیمت پر خریدنے کی استطاعت رکھتے تھے۔

HBAR ٹوکن Hedera پبلک نیٹ-ورک میں دوہرے کردار کا حامل ہے۔

اوّلین اور اہم بات، HBAR وہ ایندھن ہے جو Hederaخدمات کو طاقت فراہم کرتا ہے، جیسے [سمارٹ کونتریکٹس](https://coinmarketcap.com/alexandria/glossary/smart-contract)، فائل اسٹوریج اور باقاعدہ لین-دین۔ دوسری بات، یہ نیٹ-ورک کے تحفّظ میں مُعاونت کے لیے استعمال ہوتا ہے، کیونکہ HBAR کے صارفین پلیٹ فارم کی سالمیت کو برقرار رکھنے میں کُمک کے لیے اپنے ٹوکنز کی اسٹیکنگ کر سکتے ہیں۔

### Hedera Hashgraph کے بانی کون ہیں؟

Hedera Hashgraph کے دو بانی ہیں: Dr. Leemon Baird اور Mance Harmon۔

Dr. Leemon Baird کو ہیشگراف کے تقسیم شدہ اتفاق رائے الگورتھم کے سرمایہ کار کی حیثیت سے معتبر گردانا جاتا ہے۔ وہ فی الحال Hedera کے چیف سائیسدان کے طور پر کام کر رہے ہیں۔

Hedera Hashgraph کی بنیاد رکھنے سے پہلے، Baird نے کمپیوٹر سائنس اور سیکیورٹی سے متعلق مختلف کردار ادا کیے، اور ایک دہائی سے زیادہ تجربہ حاصل کیا۔ اس سے قبل، اُنہوں نے Cyberspace Research کے Academy Center میں سینئر تحقیقی سائنسدان کے طور پر بھی کام کیا۔ وہ DApps بنانے والے ایک پلیٹ فارم Swirlds Inc میں شریک بانی کی حیثیت سے CTO کے عہدے پر بھی فائز ہیں۔

دوسری طرف، Mance Harmon بحیثیت ایک تجربہ کار ٹیکنالوجی ایگزیکٹو اور سینیئر کاروباری شخصیت، Hedera کے CEO ہیں۔ Harmon نے ممتاز فرموں میں ایگزیکٹیو نوعیت کی ذمہ داریاں انجام دی ہیں، اور اس حوالے سے اُنکا تجربہ تقریباً دو دہائیوں پر مُحیط ہے، جن میں سے اکثر آئی ٹی سیکیورٹی صنعت سے وابستہ ہیں۔ ڈاکٹر Dr. Leemon Baird کی طرح، Mance Harmon بھی Swirlds Inc. کے شریک بانی کی حیثیت سے CEO کے عہدے پر فائز ہیں۔

بانیوں کے علاوہ، Hedera کی قائد ٹیم مزید ایک درجن سے زیادہ افراد پر مشتمل ہے جن میں زیادہ تر افراد پیشہ ورانہ لحاظ سے مُمتاز درجے پر فائز ہیں۔

### Hedera Hashgraph کو کیا چیز مُنفرد بناتی ہے؟

زیادہ تر دیگر کریپٹو کرنسی پلیث فارمز کے بر عکس، Hedera Hashgraph کو روایتی [بلاک چین](https://coinmarketcap.com/alexandria/glossary/blockchain) کے عین اُوپر تعمیر نہیں کیا گیا۔ بلکہ، یہ مکمل طور پر ایک انوکھی تقسیم شدہ لیجر کی ٹیکنالوجی متعارف کراتا ہے جسے Hashgraph کہا جاتا ہے۔

یہ ٹیکنولوجی بلاک چین پر مبنی متعدد مُتبادلات کے بالمُقابل کئی کلیدی شعبہ جات میں بہتر کارکردگی کی حامل ہے، بشمول رفتار، لاگت اور وسعت پذیری۔ Hedera کے لین-دین کی فیس ایک اوسط سی شرح یعنی صرف $0.0001 USD کے برابر ہے ، اور اس کی تکمیل عام طور پر پانچ سیکنڈ میں انجام پاتی ہے۔ مجموعی طور پر، Hedera Hashgraph کا دعویٰ ہے کہ وہ 10,000 سے بھی زیادہ لین دین ایک سیکنڈ (TPS) میں نمٹا سکتا ہے — تقریباً 5-20 مقبول ترین پروف-آف-ورک (PoW) پر مبنی بلاک چینز کے ساتھ موازنہ کرنے پر۔

یہ پلیٹ فارم بہت سی اہم نیٹ-ورک خدمات پیش کرتا ہے۔ ان میں شامل ہیں:

* ایک ٹوکن سروس جو Hedera پر کوڈ کی صرف چند سطروں کے ساتھ صارفین کو قابلِ مُبادلہ اور ناقابلِ مُبادلہ ([NFTs](https://coinmarketcap.com/alexandria/glossary/non-fungible-token))، یعنی دونوں طرح کے ٹوکنز کو با آسانی ترتیب دینے اور مِنٹ (mint) کرنے کی اجازت دیتی ہے۔
* [اتفاق رائے](https://coinmarketcap.com/alexandria/glossary/consensus) والی ایک خدمت، جو کسی بھی ایپلیکیشن یا نیٹ-ورک کے لیے اعتماد کی ایک پرت کے طور پر کام کرتی ہے، جس میں واقعات کے تحفظ یافتہ، قابل تصدیق لاگ کی ضرورت پڑتی ہے۔
* سمارٹ کونٹریکٹ ٹولز جو ڈویلپرز کو طاقتور، اور موثر غیر مرکزی ایپلی کیشنز بنانے کی استطاعت دیتے ہیں۔
* غیر مرکزی فائل سٹوریج کی خدمات، پروف-آف-ڈیلیشن، کنٹرول شدہ تغیُّر پذیری، اور وقت پر مبنی فائل ایکسپائری جیسی خصوصیات پر مشتمل ہیں۔

### کُل کتنے Hedera Hashgraph (HBAR) کوائنز گردش میں ہیں؟

Hedera Hashgraph ٹوکن، HBAR کی زیادہ سے زیادہ کل سپلائی 50 بلین یونٹس پر مشتمل ہے۔ جنوری سن 2021 تک، اس میں سے تقریباً سات بلین گردش میں تھے – جو کل سپلائی کے تقریباً 14 فیصد کے برابر ہیں۔

Hedera باقاعدہ رپورٹس شائع کرتا ہے، جن میں یہ بتایا جاتا ہے کہ HBAR ٹوکنز کی اگلی لہر کب غیر مُقفل کی جائے گی۔ یہ رپورٹیں [یہاں](https://help.hedera.com/hc/en-us/articles/360002789198-When-are-the-next-distributions-of-hbars-scheduled-) دیکھی جا سکتی ہیں۔

[Hedera کے اپنے وسائل](https://help.hedera.com/hc/en-us/articles/360007177217-How-is-Hedera-management-compensated-#breadcrumb) کے مُطابق، پروجیکٹس کے دونوں بانیوں میں سے ہر ایک کے پاس دو بلین HBARs کی کوائن گرانٹ موجود ہے، جو کہ کل سپلائی کے 4% کے برابر ہے۔ ان ٹوکنز کی ویسٹنگ (vesting) چھ سال کی مدت پر مُحیط ہے۔

Hedera کے دیگر سینئر ایگزیکٹوز (جنہوں نے سن 2018 سے پہلے شمولیت اختیار کی) کے پاس 250 ملین، اور 300 ملین کوائنز کے درمیان کوائن-گرانٹس موجود ہیں۔ یہ ٹوکنز دسمبر سن 2021 میں ختم ہونے والی مدت کے لیے دیے گئے ہیں۔

Hedera کے [اقتصادی قرطاس الابیض](https://hedera.com/blog/new-v3-of-the-hbar-economics-whitepaper) (اشاعت شُدہ جون 2020) کے مطابق، سن 2025 تک تقریباً 17.03 بلین HBAR گردش میں آنے کا تخمینہ لگایا گیا ہے – جو کل سپلائی کا 34% ہے۔

### Hedera Hashgraph نیٹ-ورک کو کیسے تحفّظ فراہم کیا جاتا ہے؟

Hedera Hashgraph اپنے نیٹ-ورک کو محفوظ رکھنے کے لیے اتفاق رائے کا ایک اَچھوتا نظام کام میں لاتا ہے جسے ’’ہیشگراف اجماع (Hashgraph consensus‘‘ کہا جاتا ہے۔

یہ دائرہ گردی کرنے والی حاکمیتی کونسل کا استعمال کرتا ہے، جس میں 39 کی حد تک انتہائی متنوع تنظیمیں شامل ہوتی ہیں، اور جن کا پھیلاؤ 11 مختلف صنعتوں پر مُحیط ہے۔ یہ Hedera کوڈ-بیس کو ڈائریکٹ کرنے، پلیٹ فارم کے فیصلوں پر پر رائے دہی کرنے، اور Hedera پبلک نیٹ-ورک پر ابتدائی نوڈز کو چلانے میں مُلوِّث ہیں۔

Hedera پروف-آف-سٹیک (PoS) کی ایک انوکھی شکل استعمال کرتا ہے، جو HBAR صارفین کو نیٹ-ورک کی حفاظت میں مدد کے لیے اپنے وسائل اسٹیک پر لگانے کی استطاعت دیتا ہے۔ ٹھیک اس دور میں، تمام Hedera نوڈز بذات ِخود Hedera کے زیر انتظام ہوتے ہیں، یا پھر گورننگ کونسل کے اراکین ان کا انتظام سنبھالتے ہیں، لیکن مستقبل میں عوامی سسٹم پر مُنتقل ہونے کے منصوبے بھی زیر غور ہیں۔

مجموعی طور پر، Hedera کا حفاظتی سیٹ-اپ اس بات کو یقینی بناتا ہے کہ یہ "ایک ہی وقت میں عمل پذیر نہ ہونے والے" [بازنطینی فالٹ ٹولرینس](https://coinmarketcap.com/alexandria/glossary/byzantine-fault-tolerance-bft) (ABFT) کو حاصل کر لے — جس کا مطلب ہے کہ یہ دونوں باتوں کی ضمانت دے سکے، یعنی وقت، اور لین دین کے کسی سیٹ کی ترتیب کے بارے میں، چاہے ڈیٹا کی کُچھ مقدار میں تاخیر ہو جائے یا وہ ضائع ہی کیوں نہ ہو جائے۔

### آپ Hedera Hashgraph (HBAR) کہاں سے خرید سکتے ہیں؟

HBAR ایک مقبول ڈیجیٹل اثاثہ ہے جو کئی معروف ایکسچینج پلیٹ فارمز پر دستیاب ہے، بشمول، [Binance](https://coinmarketcap.com/ur/exchanges/binance/) اور Bitrex نیز [Huobi Global](https://coinmarketcap.com/ur/exchanges/huobi-global/)۔

کُچھ معروف تر HBAR ٹریڈنگ پیئرز میں HBAR/USDT, HBAR/BTC اور HBAR/ETH شامل ہیں، نیز کریپٹو کرنسی کے لیے متعدد فیاٹ اختیارات بھی موجود ہیں، جن مین HBAR/USD, HBAR/KRW اور HBAR/INR شامل ہیں۔

Quant launched in June 2018 with the goal of connecting blockchains and networks on a global scale, without reducing the efficiency and interoperability of the network. It is the first project to solve the interoperability problem through the creation of the first blockchain operating system.

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

The project is built as an operating system distributed ledger technology— and Overledger Network — for connecting different blockchain networks. The project is billed as the first OS to be built for blockchains.

The main aim of Quant — using Overledger — is to bridge the gap that exists between different blockchains. The backbone of the project is the Overledger network, which Quant bills as the ecosystem on which the future digital economy ecosystem will be built.

Overledger allows developers to build decentralized multi-chain applications (known as MApps) for their customers. For developers to build a Mapp on the network, they must hold a certain amount of Quant tokens (QNT).

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:

Stellar

Launched in 2021, the XRP Ledger (XRPL) is an open-source, permissionless and decentralized technology. Benefits of the XRP Ledger include its low-cost ($0.0002 to transact), speed  (settling transactions in 3-5 seconds), scalability (1,500 transactions per second) and inherently green attributes (carbon-neutral and energy-efficient). The XRP Ledger also features the first decentralized exchange (DEX) and custom tokenization capabilities built into the protocol. Since 2012, the XRP Ledger has been operating reliably, having closed 70 million ledgers.

VeChainThor (VET) is a versatile enterprise-grade L1 smart contract platform whose origins began in 2015. VeChain is known as a pioneer of real-world enterprise applications, and built a distributed platform powered by Internet of Things (IoT) technologies, NFC chips and blockchain to help various industries solve data-related challenges.

VeChain solves major blockchain adoption hurdles. The platform uses an intelligent two token model, VET and VTHO, separating the protocol's Store of Value and gas fee payment mechanisms, ensuring costs can be kept low and stable. Fee delegation allows smart contracts to pay gas fees on behalf of business users, and an advanced transaction model allows data to be packaged more efficiently while ensuring finality of data.

VeChain is focused on delivering a wave of incentive-based sustainability dApps through its new platform, VeBetterDAO, working closely with Boston Consulting Group to achieve adoption across enterprise and individual users, and helping  onboard the next billion users to Web3 over the coming decade.

From supply chains to sustainability, VeChain has continuously demonstrated its leading role as a driver of blockchain in business, and is dedicated to its role as a pioneer of driving real world adoption of blockchain technology.

VeChain

Founded in 2017, Chainlink is a blockchain abstraction layer that enables universally connected smart contracts. Through a decentralized oracle network, Chainlink allows blockchains to securely interact with external data feeds, events and payment methods, providing the critical off-chain information needed by complex smart contracts to become the dominant form of digital agreement.

The Chainlink Network is driven by a large open-source community of data providers, node operators, smart contract developers, researchers, security auditors and more. The company focuses on ensuring that decentralized participation is guaranteed for all node operators and users looking to contribute to the network.

Cardano is a proof-of-stake blockchain platform that says its goal is to allow “changemakers, innovators and visionaries” to bring about positive global change.

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

The open-source project also aims to “redistribute power from unaccountable structures to the margins to individuals” — helping to create a society that is more secure, transparent and fair.

Cardano was founded back in 2017, and named after the 16th century Italian polymath Gerolamo Cardano. The native ADA token takes its name from the 19th century mathematician Ada Lovelace, widely regarded as the world’s first computer programmer. The ADA token is designed to ensure that owners can participate in the operation of the network. Because of this, those who hold the cryptocurrency have the right to vote on any proposed changes to the software.

The team behind the layered blockchain say that there have already been some compelling use cases for its technology, which aims to allow decentralized apps and smart contracts to be developed with modularity.

In August 2021, Charles Hoskinson announced the launch of the Alonzo hard fork, causing Cardano price to surge, gaining 116% in the following month. On Sept. 12, 2021, the Cardano ‘Alonzo’ hard fork officially launched, bringing smart contract functionality to the blockchain. Over 100 smart contracts were deployed in the following 24 hours after the launch.

Cardano is used by agricultural companies to track fresh produce from field to fork, while other products built on the platform allow educational credentials to be stored in a tamper-proof way, and retailers to clamp down on counterfeit goods.

Cardano

Polygon (previously Matic Network) is the first well-structured, easy-to-use platform for Ethereum scaling and infrastructure development. Its core component is Polygon SDK, a modular, flexible framework that supports building multiple types of applications.

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

Using Polygon, one can create optimistic rollup chains, ZK rollup chains, stand alone chains or any other kind of infra required by the developer.

Polygon effectively transforms Ethereum into a full-fledged multi-chain system (aka Internet of Blockchains). This multi-chain system is akin to other ones such as Polkadot, Cosmos, Avalanche etc. with the advantages of Ethereum’s security, vibrant ecosystem and openness.

The $MATIC token will continue to exist and will play an increasingly important role, securing the system and enabling governance.

Polygon (formerly Matic Network) is a Layer 2 scaling solution backed by Binance and Coinbase. The project seeks to stimulate mass adoption of cryptocurrencies by resolving the problems of scalability on many blockchains.

Polygon combines the Plasma Framework and the proof-of-stake blockchain architecture. The Plasma framework used by Polygon as proposed by the co-founder of Ethereum, Vitalik Buterin, allows for the easy execution of scalable and autonomous smart contracts.

Nothing will change for the existing ecosystem built on the Plasma-POS chain. With Polygon, new features are being built around the existing proven technology to expand the ability to cater to diverse needs from the developer ecosystem. Polygon will continue to develop the core technology so that it can scale to a larger ecosystem.

Polygon boasts of up to 65,000 transactions per second on a single side chain, along with a respectable block confirmation time of less than two seconds. The framework also allows for the creation of globally available decentralized financial applications on a single foundational blockchain.

The Plasma framework gives Polygon the potential of housing an unlimited number of decentralized applications on their infrastructure without experiencing the normal drawbacks common on proof-of-work blockchains. So far, Polygon has attracted more than 50 DApps to its PoS-secured Ethereum sidechain.

MATIC, the native tokens of Polygon, is an ERC-20 token running on the Ethereum blockchain. The tokens are used for payment services on Polygon and as a settlement currency between users who operate within the Polygon ecosystem. The transaction fees on Polygon sidechains are also paid in MATIC tokens.

Polygon

RenderToken (RNDR) is a distributed GPU rendering network built on top of the Ethereum blockchain, aiming to connect artists and studios in need of GPU compute power with mining partners willing to rent their GPU capabilities out. Conceived in 2009 by OTOY, inc. CEO Jules Urbach and launched in 2017, RNDR held its first public token sale in October of that same year, followed by a private sale period lasting from January 2018 – May 2018, wherein a total of 117,843,239 RNDR were sold at a price of 1 RNDR = $0.25 USD equivalent of token.
During the private sale period, early adopters were onboarded onto the RNDR Beta Testnet, where beta node operators and artists worked collaboratively with the RNDR team in building and testing the network, up until its public launch on April 27th 2020.

Render

Avalanche is a layer one blockchain that functions as a platform for decentralized applications and custom blockchain networks. It is one of Ethereum’s rivals, aiming to unseat Ethereum as the most popular blockchain for smart contracts. It aims to do so by having a higher transaction output of up to 6,500 transactions per second while not compromising scalability.

This is made possible by Avalanche’s unique architecture. The Avalanche network consists of three individual blockchains: the X-Chain, C-Chain and P-Chain. Each chain has a distinct purpose, which is radically different from the approach Bitcoin and Ethereum use, namely having all nodes validate all transactions. Avalanche blockchains even use different consensus mechanisms based on their use cases.

After its mainnet launch in 2020, Avalanche has worked on developing its own ecosystem of DApps and DeFi. Different Ethereum-based projects such as SushiSwap and TrueUSD have integrated with Avalanche. Furthermore, the platform is constantly working on improving interoperability between its own ecosystem and Ethereum, like through the development of bridges.

Avalanche

Polkadot is an open-source sharded multichain protocol that connects and secures a network of specialized blockchains, facilitating cross-chain transfer of any data or asset types, not just tokens, thereby allowing blockchains to be interoperable with each other. Polkadot was designed to provide a foundation for a decentralized internet of blockchains, also known as Web3.

Polkadot is known as a layer-0 metaprotocol because it underlies and describes a format for a network of layer 1 blockchains known as parachains (parallel chains). As a metaprotocol, Polkadot is also capable of autonomously and forklessly updating its own codebase via on-chain governance according to the will of its token holder community.

Polkadot provides a foundation to support a decentralized web, controlled by its users, and to simplify the creation of new applications, institutions and services.

The Polkadot protocol can connect public and private chains, permissionless networks, oracles and future technologies, allowing these independent blockchains to trustlessly share information and transactions through the Polkadot Relay Chain (explained further down).

Polkadot’s native DOT token serves three clear purposes: staking for operations and security, facilitating network governance, and bonding tokens to  connect parachains .

Polkadot has four core components:

Relay Chain: Polkadot’s “heart,” helping to create consensus, interoperability and shared security across the network of different chains;

Parachains: independent chains that can have their own tokens and be optimized for specific use cases;

Parathreads: similar to parachains but with flexible connectivity based on an economical pay-as-you-go model;

Bridges: allow parachains and parathreads to connect and communicate with external blockchains like Ethereum.

Polkadot

The Graph is an indexing protocol for querying data for networks like Ethereum and IPFS, powering many applications in both DeFi and the broader Web3 ecosystem. Anyone can build and publish open APIs, called subgraphs, that applications can query using GraphQL to retrieve blockchain data. There is a hosted service in production that makes it easy for developers to get started building on The Graph and the decentralized network will be launching later this year. The Graph currently supports indexing data from Ethereum, IPFS and POA, with more networks coming soon.

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

To date, over3,000 subgraphs have been deployed by thousands of developers, for DApps like Uniswap, Synthetix, Aragon, AAVE, Gnosis, Balancer, Livepeer, DAOstack, Decentraland and many others. The Graph usage has been growing at over 50% MoM and hit over 7 billion queries during the month of September 2020.

The Graph has a global community, including over 200 Indexer Nodes in the testnet and more than 2,000 Curators in the Curator Program as of October 2020. To fund network development, The Graph raised funds from community members, strategic VCs and influential individuals in the blockchain community including Coinbase Ventures, DCG, Framework, ParaFi Capital, CoinFund, DTC, Multicoin, Reciprocal Ventures, SPC, Tally Capital and others. The Graph Foundation also successfully completed a public GRT Sale with participation from 99 countries (not including the U.S.). To date as of November 2020, The Graph has raised ~$25M.

The Graph

NEAR Protocol is a layer-one blockchain that was designed as a community-run cloud computing platform and that eliminates some of the limitations that have been bogging competing blockchains, such as low transaction speeds, low throughput and poor interoperability. This provides the ideal environment for DApps and creates a developer and user-friendly platform. For instance, NEAR uses human-readable account names, unlike the cryptographic wallet addresses common to Ethereum. NEAR also introduces unique solutions to scaling problems and has its own consensus mechanism called “Doomslug.”

NEAR Protocol is being built by the NEAR Collective, its community that is updating the initial code and releasing updates to the ecosystem. Its declared goal is to build a platform that is “secure enough to manage high value assets like money or identity and performant enough to make them useful for everyday people.”

Flux, a protocol that allows developers to create markets based on assets, commodities, real-world events, and Mintbase, an NFT minting platform are examples of projects being built on NEAR Protocol.

NEAR Protocol

Filecoin is a decentralized storage system that aims to “store humanity’s most important information.” The project raised $205 million in an initial coin offering (ICO) in 2017, and initially planned a launch date for mid-2019. However, the launch date for the Filecoin mainnet was pushed back until block 148,888, which is expected in mid-October 2020.

The project was first described back in 2014 as an incentive layer for the Interplanetary File System (IPFS), a peer-to-peer storage network where users pay for data storage and distribution services in $FIL. Filecoin is open protocol and backed by a blockchain that records commitments made by the network’s participants, with transactions made using FIL, the blockchain’s native currency. The blockchain is based on both proof-of-replication and proof-of-spacetime.

Filecoin is open-source and decentralized, which means that all governance is in the hands of the community. On the Filecoin platform, developers have the opportunity to create cloud file storage services like Dropbox or iCloud. Anyone can join Filecoin and start storing their data or earn money by providing space for someone else's funds. The creators of Filecoin opted for their blockchain technology to run the network and their token with their own consensus.

$FIL is the native currency of Filecoin that powers the entire network and all processes. Clients pay for transactions in FIL tokens. Miners place FIL as collateral, guaranteeing their services.

The developers claim that Filecoin solves the problem of inefficient file storage and retrieval. Customers can find the right solution with an efficient set of tools and its core development, IPFS.

Filecoin

In a nutshell, Cosmos bills itself as a project that solves some of the “hardest problems” facing the blockchain industry. It aims to offer an antidote to “slow, expensive, unscalable and environmentally harmful” proof-of-work protocols, like those used by Bitcoin, by offering an ecosystem of connected blockchains.

The project’s other goals include making blockchain technology less complex and difficult for developers thanks to a modular framework that demystifies decentralized apps. Last but not least, an Interblockchain Communication protocol makes it easier for blockchain networks to communicate with each other — preventing fragmentation in the industry.

Cosmos’ origins can be dated back to 2014, when Tendermint, a core contributor to the network, was founded. In 2016, a white paper for Cosmos was published — and a token sale was held the following year. ATOM tokens are earned through a hybrid proof-of-stake algorithm, and they help to keep the Cosmos Hub, the project’s flagship blockchain, secure. This cryptocurrency also has a role in the network’s governance.

Cosmos

The XDC Network is a blockchain developed to support trade finance and the tokenization of RWAs. A highly optimized, EVM-compatible Layer 1 blockchain, XDC Network reaches consensus through a delegated proof-of-stake (dPoS) mechanism, which allows for a transaction time of mere seconds, near zero gas fees, and a high number of transactions per second (TPS).

Secure, scalable, and highly efficient, the XDC Network powers a wide range of novel blockchain use cases and provides state-of-the-art infrastructure for enterprise-grade blockchain applications. With architecture that enables the creation of sovereign sub-networks, XDC Network is uniquely equipped to support those who require dedicated blockchain environments for enhanced permissions and control, such as government agencies, financial institutions, and businesses.

As of April 25, 2024, there are 312 XDC Network validator masternode candidates, of which 108 actively operate as validator masternodes, and the remainder are standby masternodes. Each masternode operator is required to stake 10M XDC.

A forthcoming upgrade to the consensus mechanism, dubbed XDC 2.0, is currently running on testnet. It and subsequent iterations of the XDC Network protocol will further enhance the security of the consensus mechanism and incorporate a novel "judiciary branch" into the consensus mechanism.

Developed by Princeton University's Pramod Viswanath, Hash Laboratories' Fisher Yu, and their team, XDC 2.0’s cutting-edge compliance technology will ensure unprecedented Byzantine fault tolerance (BFT) by holding validators accountable for their actions on an automated yet discretionary basis.

Solana is a highly functional open source project that banks on blockchain technology’s permissionless nature to provide decentralized finance (DeFi) solutions. While the idea and initial work on the project began in 2017, Solana was officially launched in March 2020 by the Solana Foundation with headquarters in Geneva, Switzerland.

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

The Solana protocol is designed to facilitate decentralized app (DApp) creation. It aims to improve scalability by introducing a proof-of-history (PoH) consensus combined with the underlying proof-of-stake (PoS) consensus of the blockchain.

Because of the innovative hybrid consensus model, Solana enjoys interest from small-time traders and institutional traders alike. A significant focus for the Solana Foundation is to make decentralized finance accessible on a larger scale.

Fantom is a directed acyclic graph (DAG) smart contract platform providing decentralized finance (DeFi) services to developers using its own bespoke consensus algorithm.

Together with its in-house token FTM, Fantom aims to solve problems associated with smart-contract platforms, specifically transaction speed, which developers say they have reduced to under two seconds.

The Fantom Foundation, which oversees the Fantom product offering, was originally created in 2018, with the launch of OPERA, Fantom’s mainnet, coming in December 2019.

Fantom is an open-source decentralized smart contract platform for DApps and digital assets that was created as an alternative to Ethereum. Fantom has the goal of overcoming the limitations of previous generation blockchains and balancing three components: scalability, security and decentralization. The project offers a set of tools to simplify the process of integrating existing DApps, as well as a detailed staking reward system and built-in DeFi instruments.

Fantom is a Layer-1 blockchain that uses a scratch-built consensus mechanism and independent consensus layer, Lachesis, to facilitate DeFi and related services on the basis of smart contracts. Lachesis provides security for other layers as well, including Opera, Fantom's EVM-compatible smart contract chain. The long-playing mission of the project is to “grant compatibility between all transaction bodies around the world.”

One of Fantom's key strengths is its performance and efficient transaction processing, namely thousands of transactions per second, where transactions are settled in 1-2 seconds, and the cost is fractions of a cent per transaction. As a result, Fantom provides higher scalability but at a lower cost.

The ecosystem is based on two main technologies: Lachesis protocol and Opera.

The Lachesis protocol is the core consensus layer that secures the Fantom network by providing both transaction speed and security.

Lachesis is an aBFT consensus engine that uses a directed acyclic graph (DAG) algorithm. How it works: network data can be processed at different times, and the network filters the participants, allowing only one third, which are allocated due to erroneous or malicious behavior, without compromising network processes.

Fantom's Asynchronous Byzantine Fault Tolerant (aBFT) Proof-of-Stake (PoS) consensus mechanism maintains the efficiency of the entire network, its design provides security at maximum speed. Fantom developers emphasize that the PoS mechanism is a leaderless phenomenon — there are no leaders of blocks and participants, and anyone can join (or leave) the network of nodes at a convenient moment.

The key qualities of Lachesis are: asynchronous, leaderless, Byzantine fault-tolerant, and near-instant finality.

As for Opera, it's an application development layer or Fantom's mainnet deployment platform, permissionless and open-source hosting DApps. Thanks to EVM integration and support for the Solidity programming language, Fantom has a full set of smart contract capabilities, which allows users to seamlessly interact with Ethereum platforms while maintaining the advantage of Fantom's transaction efficiency.

The Fantom Foundation concluded that removing block leaders improves network security, so Opera uses a PoS model and leaderless validators (validators do not determine which blocks are valid).

In addition to being a fast, secure and cheap payment platform that enables to make fast and secure payments at minimal cost, Fantom also features on-chain governance where users vote with FTM tokens (one token equals one vote). Of the features: users have the right to express the degree of agreement / disagreement on a scale from 0 to 4.

FTM is the native utility in-house PoS token of Fantom that powers the ecosystem and is applied for payments, network fees, staking, and governance. FTM forms the backbone of transactions, and allows fee collection and staking activities, along with the user rewards the latter represents.
