## Tezos XTZ کیا ہے؟

Tezos اسمارٹ معاہدات پر مبنی ایک بلاک چین نیٹ-ورک ہے۔ ایک لحاظ سے، یہ نیٹ-ورک Ethereum سے کُچھ زیادہ مختلف نہیں۔ تاہم، ایک بڑا فرق موجود ہے: Tezos کا مقصد ایک جدید تر انفراسٹرکچر پیش کرنا ہے — یعنی وقت کے ساتھ ساتھ اس کا ارتقاء ہوتا رہے، اور اس میں ہارڈ فورک کی جانب سے کبھی کسی خطرے کا سامنا کیے بغیر مزید جدّت لائی جا سکتی ہو۔ یہ وہ خطرہ ہے جس سے Bitcoin اور Ethereum، دونوں کو اپنی تخلیق کے بعد تنقصان اُٹھانا پڑا۔ XTZ کے حاملین، Tezos ڈویلپرز کی جانب سے پیش کردہ پروٹوکول اپ-گریڈ کی تجاویز پر ووٹ دے سکتے ہیں۔

یہ اوپن سورس پلیٹ فارم اپنے آپ کو "قائم رہنے، اور محفوظ اپ-گریڈ کرنے کی صلاحیت کا حامل" قرار دیتا ہے۔ نیز یہ بات بھی بیان کی جاتی ہے کہ اس کی سمارٹ کنٹریکٹ لینگویج، اُس سطح کی درستگی فراہم کرتی ہے جو اعلیٰ قدر والے استعمال کے معاملات میں مطلوب ہوا کرتی ہے۔ Tezos کے اپنے نقطہِ نظر کے مُطابق، یہ مستقبل کے ساتھ ہم آھنگ ہے، یعنی "آئندہ دور میں بھی یہ ایک طویل مُّدّت تک جدید ترین ہی رہے گا"۔ اس بات سے یہ نتیجہ اخذ کیا جاتا ہے کہ بلاک چین ٹیکنالوجی میں ہونے والی پیشرفت Tezos کے لیے قابلِ قبول ہو سکتی ہے۔

Tezos کی تائید کرنے والی ٹیکنالوجی کو پہلی مرتبہ، ستمبر سن 2014 میں اجراء شدہ ایک وائٹ پیپر کے ذریعے تجویز کیا گیا تھا۔ Tezos مین-نیٹ کا آغاز ایک تاخیری سلسلے کے خاتمے پر، چار سال بعد ہوا۔

### Tezos کے بانی کون ہیں؟

Arthur Breitman وہ شخصیت تھے، جنہوں نے Tezos کا وائٹ پیپر تحریر کیا — اور [Satoshi Nakamoto](https://coinmarketcap.com/alexandria/article/who-is-satoshi-nakamoto) کی تائید کرتے ہوئے، L. M. Goodman کے قلمی نام سے اپنے دیگر کاموں کو تحریر کیا ۔ انہوں نے یہ دلیل بھی دی کہ Bitcoin کی سب سے بڑی ناکامیوں میں سے ایک، حاکمیت کے عمل کی کمی تھی، جس پر نیٹ-ورک کا استعمال کرنے والی کمیونٹی کو تعاون کی دعوت دی گئی — ساتھ ہی یہ حقیقت بھی کہ اس بلاک چین کے ذریعے نئے ٹوکن جاری نہیں کیے جا سکے تھے۔

اُنہوں نے اور ان کی اہلیہ کیتھلین نے Dynamic Ledger Solutions کے نام سے ایک اسٹارٹ اپ قائم کیا جس کو کوڈ لکھنے کا کام سونپا گیا، جو Tezos پروٹوکول کو سہارا بھی دے گا۔ اس کمپنی کو بعد میں Tezos فاؤنڈیشن نے خریدا لیا، تاکہ یہ یقینی بنایا جا سکے کہ اس کے پاس نیٹ-ورک سے متعلق تمام املاک کے دانشورانہ-ملکیتی-حقوق موجود ہیں۔

### کیا چیز Tezos کو منفرد بناتی ہے؟

اگرچہ بلاک چینز میں اسٹیکنگ کرنا عام بات ہے، لیکن اس عمل کے دوران Tezos ایک منفرد موڑ اختیار کرتا ہے۔ شرکاء "بیکنگ" کے ذریعے نیٹ-ورک کی حاکمیت میں شامل ہو سکتے ہیں، جہاں وہ مؤثر طرز پر 8,000 XTZ کی اسٹیکنگ کرتے ہیں۔ نوٹ: Tezos بلاک چین میں موجود بلاکس پر دستخط کرنے اور شائع کرنے کے عمل کو baking کہا جاتا ہے۔ یہ طریقِ کار دیانت داری سے کام کرنے کے لیے مالی ترغیب پیدا کرتا ہے۔

پھر بیکرز کو مجوزہ تبدیلیوں پر ووٹ ڈالنے کا کام سونپا جاتا ہے۔ بلاک چین کے کوڈ پر چار قدمی طریقہ کار کے ہمراہ تقریباً 23 دن لگتے ہیں۔ جن تجاویز کو شرکاء کی اکثریت تعاون فراہم کرے، اُنہیں 48 گھنٹوں کے لیے اپنی اپنی رفتار کے مُطابق ایک ٹیسٹ-نیٹ پر ڈال دیا جاتا ہے، اور ایک بڑی اکثریت کی حمایت حاصل ہونے کی صورت میں، مکمل طور پر نافذ کر دیا جاتا ہے۔

Tezos اس وجہ سے بھی انفرادیت کا حامل ہے، کہ اعلیٰ درجے کے کاروباروں نے اس کا استعمال شروع کر دیا ہے۔ ستمبر سن 2020 میں، یہ اعلان کیا گیا تھا کہ فرانسیسی دیوقامت بینکنگ کمپنی Societe Generale نے مرکزی بینک کی ڈیجیٹل کرنسی کے ساتھ تجربہ کرنے کے لیے اسی بلاک چین کو استعمال کرنے کا منصوبہ بنایا تھا۔

Binance اور Coinbase جیسے بڑے کرپٹو کرنسی ایکسچینجز نے بھی Tezos پر اسٹیکنگ کے لیے حمایت کی نقاب کشائی کر دی، یعنی صارفین اپنی گرفت میں موجود XTZ کی بنیاد پر بھی انعامات حاصل کر سکتے ہیں۔ یہ ڈیجیٹل اثاثوں میں بہت زیادہ دیکھائی دینے والی خصوصیت نہیں ہے۔

### کُل کتنے Tezos (XTZ) کوائنز گردش میں ہیں؟

ہمارا ڈیٹا ظاہر کرتا ہے کہ اس تحریر کے وقت 743,862,304 XTZ گردش میں ہیں۔

Tezos کے لیے ٹوکن کی فروخت جولائی سن 2017 میں روک دی گئی — اور اس ICO کے دوران، کل 65,681 BTC اور 361,122 ETH اکھٹا کیا گیا تھا۔ اُس وقت، اِس کی مالیت $232 ملین تھی، جس نے کوائنز کی اب تک مُنعقد ہونے والی سب سے بڑی ابتدائی-پیشکشوں میں یکتائےِ روزگار کی حیثیت سے اپنا مقام حاصل کیا۔

جبکہ اس ابتدائی سپلائی کا 80% سرمایہ کاروں کے مابین، اور بقیہ 20% Tezos Foundation، اور Dynamic Ledger Solutions کے درمیان یکساں طور پر تقسیم کر دیا گیا۔

مین-نیٹ کے آغاز میں کچھ ناراض سرمایہ کاروں کی طرف سے دائر کیے گئے کئی مقدمات کے سبب تاخیر ہوئی۔ ان مقدمات میں اُنکا استدلال یہ تھا کہ XTZ کی رقم غیر رجسٹر شدہ سیکیورٹیزکے زُمرے میں آتی ہے۔

### Tezos نیٹ-ورک کو کیسے محفوظ بنایا جاتا ہے؟

دیگر بلاک چینز کی طرح، Tezos ایک [پروف-آف-اسٹیک](https://coinmarketcap.com/alexandria/article/proof-of-work-vs-proof-of-stake) اتفاق رائے کا طرز عمل استعمال کرتا ہے۔

کوئی بھی فرد تصدیق کنندہ بن سکتا ہے، اور سیکیورٹی جمع کروا کے نیٹ-ورک کو رواں رکھنے میں اپنے حصّے کا کردار ادا کر سکتا ہے۔ ایماندارانہ رویے کی حوصلہ افزائی کے لیے، بلاک چین کے بہترین مفاد میں کام کرنے والوں کو انعامات دیے جاتے ہیں — اور بے ایمانی کا مُظاہرہ کرنے والا، کُلّی طور پر اپنے حصے سے محروم ہو سکتا ہے۔

### آپ Tezos (XTZ) کہاں سے خرید سکتے ہیں؟

گاہے بہ گاہے "tez" کے مُختصر نام سے پہچانا جانے والا XTZ، زیادہ تر بڑے ایکسچینجز سے خریدا جا سکتا ہے — بشمول Binance، Coinbase وغیرہ۔ تجارتی پیئرز XTZ کو فیاٹ کرنسیوں کے ساتھ ساتھ دیگر کریپٹو کرنسیوں، جیسے Bitcoin کے ساتھ جوڑتے ہیں۔ [اگرآپ فیاٹ کو Bitcoin میں تبدیل کرنا چاہیں، تو اس بارے میں ایک جامع گائیڈ یہاں پڑھ سکتے ہیں](https://coinmarketcap.com/how-to-buy-bitcoin/)۔

The EOS Network is an open-source blockchain platform that prioritizes high performance, flexibility, security, and developer experience. As a third-generation blockchain platform powered by the EOS virtual machine, EOS has an extensible WebAssembly engine for deterministic execution of near fee-less transactions.

EOS is the market's most scalable, divisible, and programmable digital currency. EOS is a Delegated Proof of Stake (DPoS) network where stakeholders have the authority to select node operators. Due to the decentralized nature of the token distribution on EOS, power doesn't reside in the hands of block miners, but rather all parties involved in the EOS Network.

The EOS Network is attractive because of its technology and community. It allows developers to build projects that other blockchains cannot support. The network is straightforward and has multiple tools and educational resources to help users acclimate to the blockchain.

Algorand is a self-sustaining, decentralized, blockchain-based network that supports a wide range of applications. These systems are secure, scalable and efficient, all critical properties for effective applications in the real world. Algorand will support computations that require reliable performance guarantees to create new forms of trust.

The Algorand mainnet became live in June 2019, and was able to handle almost 1 million transactions per day as of December 2020. Algorand transaction metrics can be viewed here. Algorand initial coin offering (ICO) was held in June 2019, with the Algorand price of $0.24 per token.

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.

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:

Decentraland (MANA) defines itself as a virtual reality platform powered by the Ethereum blockchain that allows users to create, experience, and monetize content and applications.

In this virtual world, users purchase plots of land that they can later navigate, build upon and monetize.

Decentraland was launched following a $24 million initial coin offering (ICO) that was conducted in 2017. The virtual world launched its closed beta in 2019 and opened to the public in February 2020. Since then, users have created a wide range of experiences on their parcels of LAND, including interactive games, sprawling 3D scenes and a variety of other interactive experiences.

Decentraland uses two tokens: MANA and LAND. MANA is an ERC-20 token that must be burned to acquire non-fungible ERC-721 LAND tokens. MANA tokens can also be used to pay for a range of avatars, wearables, names, and more on the Decentraland marketplace.

Decentraland (MANA) is a decentralized virtual world platform with software based on the Ethereum blockchain, where users create, test and monetize content. In short: users buy virtual plots of land as NFTs with MANA tokens on the Decentraland platform. Progress in the game depends only on players themselves, their efforts and their imagination.

The digital platform is completely owned by its users. Within the Decentraland metaverse, participants can explore the virtual world, purchase plots of land that can be monetized, create works of art, own non-fungible tokens (NFTs), and take part in a decentralized autonomous organization of the platform Decentraland DAO. Due to the DAO, the community influences the development vector of the project.

In addition, users have access to interactive applications, in-world payments and peer-to-peer communication. The 3D world resonates with many participants as Decentraland has many applications, both entertainment for gamers and business for investors.

Two types of tokens called MANA and LAND govern operations in Decentraland. They also allow users to interact with the platform.

MANA is the official currency of Decentraland. It’s an ERC-20 standard token that powers the Decentraland platform. With MANA, users can purchase plots of LAND, as well as pay for in-game items and services.

MANA gives its holders the right to vote in Decentraland DAO. MANA can be purchased on a cryptocurrency exchange or by selling collectibles on Decentraland Marketplace. The owner of tokens converts them to wrapped MANA, or wMANA, and then commits them to the DAO. One wMANA equals one vote. MANA can be exchanged for fiat currency and other digital assets.

As for LAND, it’s a non-fungible token (NFT) based on Ethereum (ETH). It is used to track ownership of land parcels aka digital real estate. Like MANA, LAND is part of the protocol and confers voting rights, but LAND does not need to be fixed in the DAO. One LAND is equal to two thousand votes.

Players choose what to do with their land. Owners store tokens in crypto wallets and buy necessities with MANA tokens on the Decentraland Marketplace. Moreover, on the marketplace, participants can manage or exchange LAND tokens (priced in MANA). Holders use the marketplace to transact or transfer in-game items. All transactions are conducted, regulated and registered via the Ethereum blockchain.

Decentraland combines an online gaming space and blockchain technology. All control over the rules is given to the players, and token holders vote on in-game and organizational policies. The original goal was to form a decentralized virtual reality, but in practice, Decentraland has turned into a massive NFT market.

A special role in Decentraland is assigned to NFTs, such as collectibles, virtual equipment and real estate (LAND). However, for new players who want to join the universe and seize NFTs, the entry barrier will be high.

The Decentraland protocol is built on three levels using Ethereum smart contracts. On the consensus layer, the ownership of LAND is tracked and managed. The land content layer displays the content of the Decentraland virtual world. Finally, on the real-time layer, participants interact with each other.

The platform was co-founded by two blockchain experts, Ari Meilich and Esteban Ordano, in 2015. Officially it was launched a year later and became available only in February 2020, gradually turning from a 2D experiment into a full-fledged 3D world.

To sum up, Decentraland is a decentralized game and a 3D virtual reality platform where players own lands and create limitlessly. Decentralized Autonomous Organization (DAO) software is at the core, and governance is in the hands of the community. Through the native token MANA, players participate in any proposals for managing and improving the ecosystem, the auction system, and the in-game policy.

Chiliz is the leading digital currency for sports and entertainment by the eponymous Malta-based FinTech provider. It operates the blockchain-based sports entertainment platform Socios, which enables users to participate in the governance of their favorite sports brands. Multiple fan tokens by Socios.com are an example of that. For sports clubs and associations, fan tokens offer a way of connecting with their fans and unlocking new revenue streams.

For instance, fans can participate and influence club-related decisions through surveys and polls, such as messages the captain should wear on his armband. The company aims to bridge the gap between being an active and a passive fan. Chiliz has developed partnerships with some of the biggest sporting institutions in the world: FC Barcelona, Manchester City, Juventus Turin, and Paris Saint-Germain. It also boasts partnerships with the UFC and gaming organizations. By purchasing CHZ, fans get access to various fan tokens and literally have a stake in their club.

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.

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.

Enjin Coin is a project of Enjin, a company that provides an ecosystem of interconnected, blockchain-based gaming products. Enjin's flagship offering is the Enjin Network, a social gaming platform through which users can create websites and clans, chat, and host virtual item stores.

Enjin allows game developers to tokenize in-game items on the Ethereum blockchain. It uses Enjin Coin, an ERC-20 token, to back the digital assets issued using its platform, meaning that items can be bought, sold and traded with real-world value.

Enjin Coin was first announced in July 2017, and it launched on the Ethereum mainnet in June 2018.

Enjin Coin (ENJ) is a digital store of value used to back the value of blockchain assets like non-fungible tokens (NFTs).
Every asset minted with the Enjin Platform contains ENJ, a minting resource which is locked inside NFTs and removed from circulation. Minting blockchain assets with ENJ provides a variety of benefits to creators and users:

Infuses them with a reserve value

Ensures their transparency and scarcity

Gives them instant liquidity

Provides utility in games and apps

Anti-inflationary

Enjin's "melting" functionality allows users to destroy their blockchain assets at any time to retrieve the ENJ value from within.

The Enjin blockchain ecosystem aims to offer software products that make it easy for everyone to develop, trade, monetize, and market with blockchain.

Founded in 2009, Enjin has roots in the gaming industry, with the company’s first product, a gaming community platform called the Enjin Network, growing to 20 million users over the course of a decade.

In 2017 following an ICO, Enjin established itself as a leading blockchain ecosystem developer, building a suite of software products that enable anyone to easily mint, manage, trade, distribute, and integrate blockchain assets.

Enjin’s co-founder Witek Radomski wrote the code for one of the first ever non-fungible tokens (NFTs) and is also the co-author of the ERC-1155 Ethereum token standard.

Built on top of an on-chain infrastructure, the Enjin ecosystem enables game developers and businesses of all sizes to use tokenized digital assets as part of their acquisition, retention, engagement, and monetization strategies. The Enjin ecosystem is fueled by Enjin Coin (ENJ), a cryptocurrency used to back the value of blockchain assets.

Uniswap is a popular decentralized trading protocol, known for its role in facilitating automated trading of decentralized finance (DeFi) tokens.

An example of an automated market maker (AMM), Uniswap launched in November 2018, but has gained considerable popularity this year thanks to the DeFi phenomenon and associated surge in token trading.

Uniswap aims to keep token trading automated and completely open to anyone who holds tokens, while improving the efficiency of trading versus that on traditional exchanges.

Uniswap creates more efficiency by solving liquidity issues with automated solutions, avoiding the problems which plagued the first decentralized exchanges.

In September 2020, Uniswap went a step further by creating and awarding its own governance token, UNI, to past users of the protocol. This added both profitability potential and the ability for users to shape its future — an attractive aspect of decentralized entities.

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

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.

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.

Fantom

IOTA is a distributed ledger technology (DLT) that features unique architecture and an open-source product suite for individuals, businesses, and institutions to use in Web3. It is built on a directed acyclic graph (DAG) called the Tangle, which can be pictured as a multi-dimensional blockchain. It enables the exchange of data and value on a decentralized platform through direct and secure transfers, executed on and immutably recorded on the network.

To learn more about this project, check out our deep dive into IOTA.

Together with its staging network Shimmer, IOTA aims to offer solutions to establish a secure and permissionless infrastructure that can drive the economy of the future. It enables the development of decentralized applications through automated trust in the form of Ethereum-compatible smart contracts, an advanced consensus algorithm, and thoughtfully balanced incentives.

IOTA delivers tools for creating and managing custom Layer 2 (EVM) chains, deploying smart contracts, minting native tokens and NFTs with distinctive features, and introducing digital identities to users.

Launching in 2024, IOTA 2.0 will be a protocol upgrade that rebuilds IOTA’s architecture to deliver full decentralization. You can find more about it here.

IOTA

Axie Infinity is a blockchain-based trading and battling game that is partially owned and operated by its players.

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

Inspired by popular games like Pokémon and Tamagotchi, Axie Infinity allows players to collect, breed, raise, battle and trade token-based creatures known as Axies.

These Axies can take various forms, and there are more than 500 different body parts available, including aquatic, beast, bird, bug, plant and reptile parts. Parts from each type class come in four different rarity scales: common, rare, ultra rare and legendary — and Axies can have any combination of body parts, making them highly variable and often rare and unique.

Each Axie is a non-fungible token (NFT) with different attributes and strengths and can be entered into 3v3 battles, with the winning team earning more experience (exp) points that are used to level up an Axie's stats or evolve their body parts. These Axies can be bred together to produce new and unique offspring, which can be used or sold on the Axie marketplace.

The Axie Infinity ecosystem also has its own unique governance token, known as Axie Infinity Shards (AXS). These are used to participate in key governance votes and will give holders a say in how funds in the Axie Community Treasury are spent.

Axie Infinity

MultiversX is a blockchain protocol that offers true horizontal scalability by using all aspects of sharding (Network, Transaction & State). The project describes itself as a technology ecosystem for the new internet, which includes decentralized finance, real world assets and the Metaverse. Its smart contracts execution platform is reportedly capable of up to 100,000 transactions per second, 6-second latency and a $0.002 transaction cost.

MultiversX is governed and secured through the EGLD token. EGLD, or Electronic Gold, is MultiversX's native token. It acts as a store of value currency to pay for network usage. The coin also serves as a medium of exchange between platform users and validators. Users pay transaction fees in EGLD and validators participate in the consensus process.

EGLD allows developers to deploy smart contracts, protocols, and dApps on the platform. It empowers participants to perform any network action. Through staking and validation rewards, as well as transaction fees, EGLD manages the MultiversX network. Plus, EGLD is endowed with the functionality of a governance token, so its holders can vote on network decisions.

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.
