## स्टैक्स (STX) क्या है?
 
 स्टैक एक लेयर -1 ब्लॉकचेन समाधान है जिसे स्मार्ट कॉन्ट्रैक्ट और विकेंद्रीकृत अनुप्रयोगों ([DApps](https://coinmarketcap.com/alexandria/glossary/decentralized-applications-dapps)) को [बिटकॉइन (BTC) में](https://coinmarketcap.com/hi/currencies/bitcoin/) लाने के लिए डिज़ाइन किया गया है। इन स्मार्ट कॉन्ट्रैक्ट्स को बिटकॉइन में बिना किसी फीचर को बदले लाया जाता है जो इसे इतना शक्तिशाली बनाता है - जिसमें इसकी सुरक्षा और स्थिरता शामिल है।
 
 ये DApps ओपन और मॉड्यूलर हैं, जिसका अर्थ है कि डेवलपर्स एक-दूसरे के ऐप के शीर्ष पर ऐसी सुविधाओं का निर्माण कर सकते हैं जो एक नियमित ऐप में संभव नहीं हैं। चूंकि स्टैक बिटकॉइन को आधार परत के रूप में उपयोग करता है, नेटवर्क पर जो कुछ भी होता है वह सबसे व्यापक रूप से उपयोग किए जाने वाले यकीनन संचालन में [सबसे सुरक्षित ब्लॉकचेन - बिटकॉइन पर बसा होता है।](https://coinmarketcap.com/alexandria/glossary/blockchain)
 
 मंच स्टैक टोकन (STX) द्वारा संचालित है, जिसका उपयोग स्मार्ट कॉन्ट्रैक्ट के निष्पादन को बढ़ावा देने, लेनदेन को संसाधित करने और स्टैक 2.0 ब्लॉकचैन पर नई डिजिटल संपत्तियों को पंजीकृत करने के लिए किया जाता है।
 
 प्लेटफ़ॉर्म को पहले ब्लॉकस्टैक के रूप में जाना जाता था, लेकिन मूल प्रोटोकॉल बनाने वाली कंपनी "ब्लॉकस्टैक पीबीसी से इकोसिस्टम और ओपन सोर्स प्रोजेक्ट को अलग करने" के लिए Q4 2020 में स्टैक को फिर से ब्रांडेड किया गया था।
 
 स्टैक 2.0 के लिए मेननेट जनवरी 2021 में लॉन्च किया गया।
 
 ### स्टैक्स के संस्थापक कौन हैं?
 
 स्टैक्स को शुरू में वाई कॉम्बिनेटर, डिजिटल करेंसी ग्रुप और विंकलेवोस कैपिटल सहित कई प्रमुख वेंचर कैपिटल फंडों द्वारा वित्त पोषित किया गया था। इसे ब्लॉकस्टैक पीबीसी द्वारा विकसित किया गया था, जिसका मुख्यालय न्यूयॉर्क में है।
 
 ब्लॉकस्टैक पीबीसी अब हिरो सिस्टम्स पीबीसी नाम से संचालित होता है और ये स्टैक्स प्लेटफॉर्म पर निर्माण करने वाली कंपनियों की एक विस्तृत श्रृंखला में शामिल होता है।
 
 ब्लॉकस्टैक पीबीसी की स्थापना मुनीब अली और रयान शी ने की थी। प्रिंसटन विश्वविद्यालय से कंप्यूटर विज्ञान में एमए और पीएचडी के साथ स्नातक होने के बाद, मुनीब अली ने 2013 में स्टैक्स की सह-स्थापना की, और आज भी हिरो सिस्टम्स पीबीसी के सीईओ के रूप में मंच के साथ काम करते हैं।
 
 मंच के दूसरे सह-संस्थापक, रयान शी ने 2013 और 2018 के बीच सह-सीईओ के पद पर कार्य किया, अन्य उपक्रमों को आगे बढ़ाने के लिए परियोजना से निकलने से पहले - एक नए तकनीकी स्टार्टअप के सह-स्थापना की, जो वर्तमान में स्टील्थ पर काम कर रहा है। स्टैक्स में अपनी भूमिका से पहले, शी ने एक सॉफ्टवेयर इंजीनियर के रूप में काम किया।
 
 ### क्या बनता है Stacks को सबसे अलग?
 
 स्टैक्स बिटकॉइन को और शक्तिशाली बना कर इसकी कार्यक्षमता को बढ़ाने का कार्य करता है वो भी बिना किसी फोर्क या मूल ब्लॉकचैन में बिना बदलाव लाये।
 
 यह अपने प्रूफ-ऑफ-ट्रांसफर (PoX) [सर्वसम्मति तंत्र के](https://coinmarketcap.com/alexandria/glossary/consensus) माध्यम से बिटकॉइन ब्लॉकचैन से सीधे जुड़कर ऐसा करता है, जिसमें माइनर्स BTC में भुगतान करके नए स्टैक (STX) टोकन को मिंट करते है। इसके अलावा, STX टोकन धारक बिटकॉइन को इनाम के रूप में अर्जित करने के लिए अपने टोकन को *stack* [*(stake नहीं) कर सकते हैं।*](https://coinmarketcap.com/alexandria/glossary/staking)
 
 स्टैक्स एक नई स्मार्ट अनुबंध प्रोग्रामिंग भाषा पेश करता है जिसे क्लैरिटी के रूप में जाना जाता है, जिसे सुरक्षित और आसान बनाने के लिए डिज़ाइन किया गया है,जो इसके आसान सिंटेक्स के कारण बहुत ही स्पष्ट है। इस स्मार्ट कॉन्ट्रैक्ट-केंद्रित प्रोग्रामिंग भाषा का उपयोग [अल्गोरंड (ALGO) ब्लॉकचेन](https://coinmarketcap.com/hi/currencies/algorand/) द्वारा भी किया जाता है।
 
 इसके शीर्ष पर, स्टैक्स संयुक्त राज्य में बिक्री के लिए एसईसी योग्यता प्राप्त करने वाली पहली क्रिप्टोकरेंसी थी, जिसने जुलाई 2019 में अपने एसटीएक्स टोकन के लिए $ 28 मिलियन Reg A+ बिक्री नकद पेशकश शुरू करने की अनुमति दी।

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.

Injective is a blockchain built for finance. It is an open, interoperable layer-one blockchain powering next-generation DeFi applications, including decentralized spot and derivatives exchanges, prediction markets, lending protocols and more.

Injective uniquely provides powerful core financial infrastructure primitives that applications can leverage, including a fully decentralized MEV-resistant on-chain orderbook. In addition, all forms of financial markets such as spot, perpetual, futures and options are fully on-chain. The decentralized cross-chain bridging infrastructure is compatible with Ethereum, IBC-enabled blockchains, and non EVM chains such as Solana.

Injective also provides a next-generation, highly interoperable smart contract platform based on CosmWasm, with advanced interchain capabilities. Injective is custom built with the Cosmos SDK and utilizes Tendermint-based Proof-of-Stake consensus mechanism, providing instant transaction finality with the ability to sustain lightning-fast performance (10,000+ TPS).

The Injective ecosystem includes 100+ projects and over 150,000 community members globally. Injective is backed by a group of prominent investors such as Binance, Pantera Capital, Jump Crypto and Mark Cuban.

Injective’s core exchange module provides state-of-the-art capabilities including an advanced on-chain order book and matching engine for spot, perpetual, futures and options markets, resistance to Miner-Extractable Value (MEV) through frequent batch auction order matching, and zero gas fees for users.

Injective natively uses IBC and is highly-interoperable with multiple layer 1s, including, but not limited to, Polygon and Solana (through an upcoming Wormhole integration). It is also uniquely built to be interoperable with Ethereum, through its own decentralized ERC-20 token bridge, making Injective the first network within the Cosmos ecosystem to natively support Ethereum assets.

Smart contracts are implemented on Injective through CosmWasm, allowing for multi-chain smart contract transactions to occur seamlessly. Injective, however, is the only blockchain that enables automatic smart contract execution. This capability serves as a powerful building block for developers to create novel use cases that would not be possible on any other chain.

The use cases intended for INJ include but are not limited to: protocol governance, dApp value capture, Proof-of-Stake (PoS) security, developer incentives and staking. Further details regarding each of these use cases can be found below:

Protocol Governance: The INJ token governs every single component of Injective, including chain upgrades. Since its mainnet launch, the Injective community has actively contributed to governance, with all proposals passing through a DAO governance vote. The comprehensive governance page is available here.

Protocol Fee Value Capture: 60% of all fees generated from dApps enter an on-chain buy-back-and-burn auction to maintain the deflationary nature of INJ. The burn auction page is available here.

Tendermint-based Proof-of-Stake (PoS) Security: INJ is used to secure the Injective blockchain using a proof-of-stake mechanism. Validators and delegators can both participate in staking.

Developer Incentives: 40% of fees generated by users on dApps built on Injective go directly towards incentivizing new developers building on Injective which brings an ever growing funnel of builders to Injective.

Injective

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.

Immutable

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.

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.

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

Arweave is a decentralized storage network that seeks to offer a platform for the indefinite storage of data. Describing itself as "a collectively owned hard drive that never forgets," the network primarily hosts "the permaweb" — a permanent, decentralized web with a number of community-driven applications and platforms.

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

The Arweave network uses a native cryptocurrency, AR, to pay "miners" to indefinitely store the network's information.

The project was first announced as Archain in August 2017, later rebranding to Arweave in February 2018 and officially launching in June 2018.

Arweave

THORChain is a decentralized liquidity protocol that allows users to easily exchange cryptocurrency assets across a range of networks including Bitcoin and Ethereum without losing full custody of their assets in the process.

With THORChain, users can simply swap one asset for another in a permissionless setting, without needing to rely on order books to source liquidity. Instead, market prices are maintained through the ratio of assets in a pool (see automated market maker.

The native utility token of the THORChain platform is RUNE. This is used as the base currency in the THORChain ecosystem and is also used for platform governance and security as part of THORChain's Sybil resistance mechanisms — since THORChain nodes must commit a minimum of 300k RUNE to participate in its rotating consensus process.

THORChain was funded through an initial DEX offering (IDO) which launched through the Binance DEX in July 2019. Its single-chain chaosnet launched in April 2021, the multi-chain upgrade was launched in April 2021 and Mainnet is now live as of Jun 2022..

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

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

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

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.

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

Synthetix is building a decentralized liquidity provisioning protocol that any protocol can tap into for various purposes. Its deep liquidity and low fees serve as a backend for many exciting protocols on both Optimism and Ethereum. Many user-facing protocols in the Synthetix ecosystem, such as Kwenta (Spot and Futures), Lyra (Options), Polynomial (Automated Options), and 1inch & Curve (Atomic Swaps), tap into Synthetix liquidity to power their protocols. Synthetix is built on Optimism and Ethereum mainnet. The Synthetix Network is collateralized by SNX, ETH, and LUSD, enabling the issuance of synthetic assets (Synths). Synths track and provide returns on the underlying asset without requiring one to directly hold the asset. This pooled collateral enables an array of on-chain, composable financial instruments backed by liquidity from Synthetix. Some of the most exciting upcoming releases from SNX are Perps V2, which hopes to enable low-fee on-chain futures trading through the usage of off-chain oracles, and Synthetix V3, which aims to rebuild the protocol to achieve its earliest goal, being a fully permissionless derivatives protocol. Learn more about Synthetix on their blog or by joining the SNX Discord.

The platform aims to broaden the cryptocurrency space by introducing non-blockchain assets, providing access to a more robust financial market.

SingularityNET is a blockchain-powered platform that allows anybody to easily "create, share, and monetize" AI services, thanks to its globally-accessible AI marketplace.

Through the SingularityNET marketplace, users can browse, test and purchase a huge variety of AI services using the platform’s native utility token — AGIX. Moreover, the marketplace represents an outlet AI developers can use to publish and sell their AI tools, and easily track their performance.

With the benefits of LLMs and generative AI are increasingly exciting, their limitations are also becoming increasingly apparent. The convergence of structured knowledge with neural networks is emerging as the key to overcoming their shortcomings.

Uniquely positioned at the heart of this convergence, SingularityNET will prioritize the integration of Knowledge Graphs (KGs) and comprehensive Neural Symbolic tools for LLMs, with the goal of empowering developers to create the next generation of AI systems on the SingularityNET Platform.

SingularityNET is strategically positioned to become the Knowledge Layer of the Internet, leading the evolution of the emerging AI landscape while also laying the foundations for the Artificial General Intelligence (AGI) of tomorrow.

The team behind SingularityNET pioneered the development of an AI known as Sophia, which is described as the "world's most expressive robot". SingularityNET’s goal is to enable Sophia to be able to fully understand human language, and continue developing “OpenCog” — an AI framework that is hoped to eventually achieve a state known as “advanced general intelligence,” i.e. human-level artificial intelligence (or beyond).

The platform was first announced in 2017 and completed an initial coin offering (ICO) in December the same year, raising $36 million in just one minute.
