## मीना प्रोटोकॉल क्या है?

मीना प्रोटोकॉल एक न्यूनतम "संक्षिप्त ब्लॉकचेन" है जिसे DApps को अधिक कुशलता से चलाने के लिए कम्प्यूटेशनल आवश्यकताओं को कम करने के लिए बनाया गया है। मीना को दुनिया के सबसे हल्के ब्लॉकचेन के रूप में वर्णित किया गया है क्योंकि इसका आकार उपयोग में वृद्धि के बावजूद स्थिर रहने के लिए डिज़ाइन किया गया है। इसके अलावा, यह सुरक्षा और डीसेंट्रलाइज़्ड के मामले में संतुलित रहता है। अक्टूबर 2020 में प्रोजेक्ट को कोडा प्रोटोकॉल से मीना में रीब्रांड किया गया था।

इस प्रोजेक्ट के बारे में अधिक जानने के लिए, [मीना प्रोटोकॉल के](https://coinmarketcap.com/alexandria/article/what-is-mina-protocol) हमारे डीप डाइव को देखें।

मीना नेटवर्क का आकार केवल 22 केबी है, जो कि बिटकॉइन के 300 जीबी ब्लॉकचैन की तुलना में बहुत कम है।

### मीना प्रोटोकॉल का मुख्य उद्देश्य क्या है?

मीना एक कुशल वितरित भुगतान प्रणाली प्राप्त करने पर काम कर रही है जो उपयोगकर्ताओं को मूल रूप से उत्पत्ति ब्लॉक से प्लेटफॉर्म को सत्यापित करने में सक्षम बनाती है। इसका तकनीकी वाइटपेपर इसे "संक्षिप्त ब्लॉकचेन" कहता है।

प्रोटोकॉल जीरो-नॉलेज सक्सेस नॉन-इंटरैक्टिव आर्गुमेंट्स ऑफ नॉलेज (zk-SNARKs) का उपयोग करता है, एक क्रिप्टोग्राफिक सबूत जो किसी को उक्त जानकारी को प्रकट किए बिना जानकारी को प्रमाणित करने में सक्षम बनाता है। हालाँकि, किसी उपयोगकर्ता को प्लेटफ़ॉर्म को उसके उत्पत्ति ब्लॉक में वापस ट्रेस करने में सक्षम करना एक बड़े नेटवर्क में अव्यावहारिक हो सकता है। जैसे, मीना वृद्धिशील रूप से SNARKS की गणना करता है जो केवल अंतिम कुछ ब्लॉकों पर ध्यान केंद्रित करता है - जिसका अर्थ है कि अंतिम-उपयोगकर्ता एक ब्लॉक के संपूर्ण लेनदेन इतिहास के बजाय उस zk-SNARK-compressed प्रमाण की जांच करते हैं।

मीना प्रोटोकॉल के केंद्र में MINA है, इसकी मूल मुद्रा, जो एक उपयोगिता कॉइन और एक्सचेंज के माध्यम के रूप में कार्य करती है।

### मीना प्रोटोकॉल कैसे कार्य करता है?

यह लेनदेन सँभालने के अलावा बिटकॉइन के समान है, लेकिन एथेरियम में उपयोग किए जाने वाले अकाउंट मॉडल को भी नियोजित करता है।

इस संबंध में, बिटकॉइन और ईथीरियम के बीच का अंतर यह है कि बिटकॉइन ब्लॉकचैन की स्थिति में अप्रयुक्त सिक्कों की एक सूची होती है, जबकि ईथीरियम की स्थिति खाता शेष से बनी होती है।

दूसरी ओर, मीना एक प्रोवर्स(या स्नार्कर, यदि आप करेंगे) का उपयोग करती है, जो माइनर के समान है। तो यह सुनिश्चित करता है की हर ब्लॉक को पूरा गया है।

मीना ने Ouroboros Samasika का उपयोग किया, एक प्रकार का PoS तंत्र जिसे विशेष रूप से संक्षिप्त डीसेंट्रलाइज़्ड नेटवर्क के लिए डिज़ाइन किया गया है क्योंकि यह एक उत्पत्ति ब्लॉक से बूटस्ट्रैपिंग प्रदान करता है।

संक्षिप्त ब्लॉकचेन में दो प्रमुख कार्य होते हैं: सत्यापित और अद्यतन। सत्यापन सर्वसम्मति, ब्लॉकचेन सारांश और ब्लॉक को छूता है, जबकि अपडेट फ़ंक्शन सर्वसम्मति और चैन सारांश के साथ इंटरैक्ट करता है।

उपरोक्त कार्यान्वयन के अलावा, प्रोजेक्ट लेनदेन प्रसंस्करण गति को अनुकूलित करने के लिए एक समानांतर स्कैन स्टेट का उपयोग करती है, जो अप्रमाणित ब्लॉकों को समूहीकृत करके और समानांतर प्रोवर्स को प्रक्रिया सौंपने का काम करती है।

#### प्रमुख मीना प्रोटोकॉल प्रतिभागी

मीना वर्तमान ब्लॉकचेन परिदृश्य में क्रांति लाने के बारे में है, जहां अधिकांश प्लेटफार्मों में सत्यापनकर्ता जैसे माइनर्स/स्टेकर और लाइट क्लाइंट होते हैं जो लेनदेन की पुष्टि करते समय तीसरे पक्ष के रूप में कार्य करते हैं।

मीना कई प्रतिभागियों के साथ एक अलग दृष्टिकोण अपनाती है, प्रत्येक डीसेंट्रलाइज़्ड नेटवर्क पर एक विशिष्ट कार्य को संभालता है।

तीन प्रमुख भूमिकाओं में सत्यापनकर्ता, ब्लॉक निर्माता और स्नार्कर शामिल हैं।

* सत्यापनकर्ता
* सत्यापनकर्ता zk-SNARKS के साथ इंटरैक्ट करते हैं जो सर्वसम्मति की जानकारी को प्रमाणित करने से संबंधित है। प्रत्येक मीना प्रोटोकॉल उपयोगकर्ता को एक सत्यापनकर्ता माना जाता है, बशर्ते कि उनके उपकरण 22KB चेन को संभाल सकें और प्रसंस्करण समय के कुछ मिलीसेकंड का सामना कर सकें।

#### ब्लॉक निर्माता

ब्लॉक निर्माता स्टेकर या माइनर्स का रूप लेते हैं और ब्लॉक पुरस्कार और लेनदेन शुल्क भुगतान अर्जित करते हैं। दिलचस्प बात यह है कि प्रोटोकॉल ब्लॉक प्रोडक्ट्स कों के प्रोत्साहन को कम नहीं करता है। प्रतिभागियों की यह श्रेणी मीना उपयोगकर्ताओं को अपने कॉइन उन्हें सौंपने की अनुमति देती है।

ब्लॉक में लेनदेन को बंडल करने के अलावा, ब्लॉक प्रोडक्ट्स कों को भी पहले से प्रतिबद्ध ट्रेडों के बराबर संख्या में SNARK करना पड़ता है क्योंकि ब्लॉक प्रोडक्ट्स न के दौरान ऐसा करने में विफलता के कारण अपूर्ण ब्लॉक और अन्य नोड्स उनकी वैधता को अस्वीकार कर देंगे।

यदि कोई ब्लॉक निर्माता चेन में 10 लेनदेन शामिल करना चाहता है, तो उन्हें कतार के सामने से SNARK ट्रेड को भी शामिल करना पड़ेगा। हालांकि, उनके पास SNARK का प्रोडक्ट्स न करने या snarkers नामक प्रतिभागियों के एक विशेष समूह द्वारा उत्पन्न उपयोग करने का विकल्प होता है।

#### स्नार्कर्स

स्नार्कर्स, जिन्हें प्रोवर्स के रूप में भी जाना जाता है, लेनदेन को सत्यापित करने में उपयोग किए जाने वाले zk-SNARKs का प्रोडक्ट्स न करते हैं।

ब्लॉक निर्माता नए ब्लॉक जोड़ने के लिए प्राप्त होने वाले कुल लेनदेन शुल्क से स्नार्कर्स का भुगतान करते हैं। हालांकि, फीस के लिए अर्हता प्राप्त करने के लिए, उन्हें बोलियां पोस्ट करनी होंगी। ध्यान दें कि एक स्नैकर के zk-SNARK को एक ब्लॉक में उपयोग करने की आवश्यकता होती है, जबकि ब्लॉक निर्माता जो इसका उपयोग करता है, वह स्नार्कर को प्रोत्साहित करने के लिए जिम्मेदार होता है।

यह एक व्यावसायिक अर्थव्यवस्था बनाता है जहां एक ही लेन-देन के लिए कई स्नार्कर्स बोलियां पोस्ट कर सकते हैं। दूसरी ओर, ब्लॉक निर्माता लाभ के लिए हैं और सबसे कम शुल्क के साथ बोली का चयन करेंगे। नतीजतन, स्नार्कर्स को कम लागत वाले SNARKS का प्रोडक्ट्स न करने की चुनौती दी जाती है।

### मीना पर लेनदेन कैसे होता है?

प्रक्रिया एक उपयोगकर्ता द्वारा लेनदेन शुरू करने के साथ शुरू होती है, जिसके बाद व्यापार मेमपूल में जाता है, जो वैध लेकिन अपुष्ट लेनदेन का एक पूल है।

इसके बाद, स्नार्कर्स सबूत या SNARKS बनाकर कब्जा कर लेते हैं। प्रक्रिया एक ब्लॉक में लेनदेन को बंडल करने के लिए एक ब्लॉक निर्माता (BP) के चयन के साथ होती है। ध्यान दें कि एक BP लाभदायक लेनदेन के लिए मेमपूल के माध्यम से निकल जाता है।

फिर, BP सर्वसम्मति तंत्र में नियमों के अनुसार एक SNARK चुनता है।

ध्यान दें कि एक ब्लॉक निर्माता सबसे कम कीमत वाले SNARK के लिए बोलियों को स्कैन करता है। इसके अलावा, हाल ही में जोड़े गए लेनदेन में एक अपडेटेड SNARKS ऑर्डर बुक है।

अगला, SNARKS को एक ब्लॉक में शामिल करने का समय है, फिर ब्लॉक को चैन में जोड़ें और नेटवर्क को अपडेट करें। प्रोटोकॉल के आकार को स्थिर रखने में मदद करने के लिए स्नार्क किए गए लेनदेन को चैन से हटा दिया जाता है।

फिर, ब्लॉक निर्माता प्रोटोकॉल के zk-SNARKS को अपग्रेड करता है।

अंत में, नया ब्लॉक अपरिवर्तनीय रूप से चैन का हिस्सा बन जाता है।

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.

Immutable positions itself as the first layer-two scaling solution for NFTs on Ethereum. According to Immutable, its blockchain does away with Ethereum’s limitations like low scalability, a poor user experience, illiquidity, and a slow developer experience. Instead, users benefit from instant trading and massive scalability while enjoying zero gas fees for minting and trading NFTs without compromising user or asset security.

Thanks to this technology, users will be able to create and distribute assets like ERC-20 and ERC-721 tokens on a massive scale. Chris Clay, the game Director of Gods Unchained, a project already building on Immutable, stated that Immutable allows Gods Unchained to implement a new meta-system that was previously impossible. In this fashion, Immutable aims to create a world-class experience for users and developers alike.

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.

Aptos is a Layer 1 Proof-of-Stake (PoS) blockchain that employs a novel smart contract programming language called Move, a Rust-based programming language that was independently developed by Meta (formerly Facebook)’s Diem blockchain engineers.

Aptos’s vision is a blockchain that brings mainstream adoption to web3 and empowers an ecosystem of DApps to solve real-world user problems.

The PoS blockchain can achieve a theoretical transaction throughput of over 150,000 transactions per second (tps) through parallel execution.

In March 2022, Aptos raised $200 million in a seed round led by the venture capital firm Andreessen Horowitz (a16z). Other crypto heavyweights like Tiger Global and Multicoin Capital took part in the funding round. Fast forward to July, the startup raised another $200 million in a Series A round with participation from Dragonfly, Apollo Global, Franklin Templeton, Animoca, Jump Crypto and others.

Two months later, Binance Labs made a strategic investment of an undisclosed amount in Aptos.

On Oct. 18, 2022, Aptos announced the mainnet launch, while the Aptos genesis occurred on Oct. 12, 2022.

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.

Optimism (OP) is a layer-two blockchain on top of Ethereum. Optimism benefits from the security of the Ethereum mainnet and helps scale the Ethereum ecosystem by using optimistic rollups. That means transactions are trustlessly recorded on Optimism but ultimately secured on Ethereum.

Optimism is one of the biggest scaling solutions for Ethereum with over $500 million in TVL. It is home to 97 protocols, the biggest being Synthetix (SNX), a derivatives exchange, Uniswap (UNI), a DEX, and Velodrome (VELO), an AMM. Users can begin their journey on Optimism by adding the chain on their Metamask and bridging tokens like ETH to the L2. On May 31, 2022, Optimism conducted a highly anticipated airdrop of its OP token.

Optimism

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.

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

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

Oasis is the pioneering layer 1 blockchain designed to enable scalability and confidential compute. Oasis is home to Sapphire, the first confidential EVM that empowers Web3 and Decentralized AI developers to build dApps with Smart Privacy natively on Oasis or other EVM-based chains.

ROSE is the native token of the Oasis Network used for gas fees, staking, delegation and governance. With a unique layered architecture, Oasis presents the optimal building and execution environment for DeFi, AI, GameFi, NFTs, the metaverse, data tokenization and DAO governance. Oasis also has native support for rollups at the consensus layer.

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.

Ethereum-based DYDX ($ethDYDX) is a governance token that allows the dYdX community to truly govern the dYdX Layer 2 Protocol built on Ethereum ("dYdX v3"). ethDYDX is currently undergoing a migration from Ethereum to the dYdX Chain. More information is available here. If you want to migrate ethDYDX to dYdX Chain DYDX, to enable staking, security and governance of the dYdX Chain you can follow the how-to-bridge guide here.

If you want to read about the new token utility for dYdX Chain DYDX you can read the blog here

ethDYDX (dYdX) is the governance token for the layer 2 protocol built on Ethereum. By enabling shared control of dYdX v3, ethDYDX allows traders, liquidity providers, and partners of dYdX to work collectively towards an enhanced dYdX v3.

Built on StarkWare’s StarkEx scalability engine, layer 2 is used for trading of cross-margined perpetuals on the platform. The scaling solution allows dYdX to increase transaction speed, eliminate gas costs, reduce trading fees and lower​​ minimum trade sizes on the protocol.

A total of 1,000,000,000 ethDYDX have been minted, and started to become accessible over five (5) years, on August 3rd, 2021, at 15:00:00 UTC.

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

Arbitrum is an Ethereum layer-two (L2) scaling solution. It uses optimistic rollups to achieve its goal of improving speed, scalability and cost-efficiency on Ethereum. Arbitrum benefits from the security and compatibility of Ethereum. Another benefit is the higher throughput and lower fees compared to Ethereum. That is made possible thanks to moving most of the computation and storage load off-chain.

Arbitrum’s native token is called ARB and is used for governance. Offchain Labs, the developers behind Arbitrum, announced the shift to a decentralized autonomous organization (DAO) structure — the Arbitrum DAO. ARB holders can vote on proposals that affect the features, protocol upgrades, funds allocation and election of a Security Council.

Arbitrum has an ambitious roadmap for 2023, which includes: Launching its own layer-three solution called Orbit; Enabling developers to deploy programs written in popular programming languages like Rust, C++, and more using Stylus; Expanding its validator set to include more independent institutional validators; Moving its protocol to layer two with Arbitrum One.

On March 16, 2023,  Arbitrum announced their highly anticipated airdrop of ARB. The token will be airdropped to early users and DAOs building on Arbitrum, with 12.75% of the total supply to be distributed. Recipients were rewarded on a point-based system depending on their interaction with the Arbitrum network until a cutoff date of March 1, 2023. The token generation event is on March 23, 2023.

Arbitrum

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.

Launched in 2011 by Pixowl, The Sandbox is a blockchain-based virtual world allowing users to create, build, buy and sell digital assets in the form of a game. By combining the powers of decentralized autonomous organizations (DAO) and non-fungible tokens (NFTs), the Sandbox creates a decentralized platform for a thriving gaming community.

According to the official whitepaper, the Sandbox platform’s main mission is to introduce blockchain technology in mainstream gaming successfully. The platform focuses on facilitating a creative “play-to-earn” model, which allows users to be both creators and gamers simultaneously. The Sandbox employs the powers of blockchain technology by introducing the SAND utility token, which facilitates transactions on the platform.

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.
