The Decentralized Storage War: Filecoin vs. Arweave

5 Things That Decentralized Storage Aims to Fix

## Что такое Storj (STORJ)?

Storj (произносится как storage «хранилище») — это платформа облачного хранения данных с открытым исходным кодом. В ней децентрализованная сеть узлов используется для размещения пользовательских данных. Платформа защищает размещенные данные с помощью продвинутого шифрования.

В опубликованном в декабре 2014 года вайтпейпере Storj впервые был представлен миру как концепция. Это должна была быть [одноранговая](https://coinmarketcap.com/alexandria/glossary/peer-to-peer-p2p) платформа децентрализованного облачного хранения зашифрованных данных.

Два года спустя был опубликован обновленный вайтпейпер. Здесь была описана децентрализованная сеть, соединяющая пользователей, которым требуется облачное хранилище, с теми, у кого есть место на жестком диске и они не против его продать. Платформа была запущена в конце 2018 года.

К сети могут присоединяться пользователи, у которых есть место на жестком диске и хорошее подключение к Интернету. Они становятся единицей в сети, т.н. узлом. За предоставление хранилища они награждаются токенами Storj.

### Кто создал Storj?

Компания Storj была основана Шоном Уилкинсоном (Shawn Wilkinson) в мае 2014 года. Уилкинсон был разработчиком программного обеспечения из Атланты. Ему пришла идея, как технологию блокчейн можно применить для создания децентрализованной сети облачного хранения.

Соавтором первого вайтпейпера был Джон Куинн (John Quinn). Вместе они опубликовали его в конце 2014 года. С тех пор концепция и детали поменялись. Текущая версия Storj V3, была запущена в середине 2019 года.

Помимо того, что он был блокчейн энтузиастом, Куинн мог похвастаться обширным опытом в развитии бизнеса. До создания собственных проектов (включая Storj) он работал в сфере инвестиционного банкинга. Концепция была окончательно зарегистрирована как компания Storj Labs Inc. в мае 2015 года.

На момент основания компании Уилкинсон занимал пост CEO. Позже он ушел в отставку, уступив место более опытному управленцу. В настоящее время Бен Голуб (Ben Golub) занимает пост CEO. Уилкинсон стал директором по стратегии (CSO), а Куинн - директором по доходам (CSO), а также членом совета директоров компании.

Платформа смогла собрать 910 биткойнов на сумму около 460 000 долларов в 2014 году в ходе публичной распродажи. Три года спустя они собрали 3 миллиона долларов в рамках посевного раунда финансирования, а затем провели продажу токенов, в результате чего было собрано еще 30 миллионов долларов.

### Что особенного в Storj?

Если смотреть на него как на децентрализованную сеть облачного хранения данных, Storj уникален во многих отношениях. Во-первых, в отличие от традиционных облачных решений для хранения, которые занимающих огромные центры обработки данных, Storj работает в сети, состоящей из тысяч независимых компьютеров.

Каждый, у кого есть несколько лишних терабайт на жестком диске, может стать узлом на платформе, установив Tardigrade. Всё, что для этого требуется, это надежное и стабильное подключение к Интернету.

Эффективность сети такова, что хосты платят гораздо меньше за хранение своих данных, чем при использовании традиционных облачных сервисов хранения.

### Сколько монет Storj находится в обращении?

Изначально было выпущено 500 миллионов токенов [Storj](https://storj.io/blog/categories/tokens) на блокчейне [Ethereum](https://coinmarketcap.com/ru/currencies/ethereum/). После того, как Storj Labs провела первую продажу токенов, 75 миллионов из них были сожжены. Сейчас общее количество токенов в обращении, составляет примерно 425 миллионов.

В 2017 году перед токенсейлом компания заблокировала 245 миллионов токенов в резерве. В ходе самой распродажи в обращение было выпущено 70 миллионов токенов.

### Как обеспечивается безопасность сети Storj?

Storj Labs Inc. использует свое ПО Tardigrade, установленное на узловых компьютерах, для создания и защиты пользовательских данных. Сеть анонимных узлов устраняет необходимость доверять поставщикам облачных хранилищ для обеспечения конфиденциальности наших данных.

Система также зашифрована в одноранговой сети, что означает, что каждый файл зашифровывается перед тем, как быть рассредоточен по сети независимых хостов. Каждый узел получает только случайный фрагмент целого файла с ключами дешифрования, разделенными между каждым узлом и хостом, что делает взлом практически невозможным.

Операторы узлов получают вознаграждение за размещение данных, а также за подтверждение безопасности и сохранности размещенных файлов случайным образом в процессе, известном как майнинг ([PoW](https://coinmarketcap.com/alexandria/article/proof-of-work-vs-proof-of-stake)). Для этого используется токен Storj. Физические лица или организации, которые хотят хранить свои данные в сети, предоставляют токены Storj, выплачиваемые узлам

Такая система гарантирует, что данные пользователя защищены от взломов и других злонамеренных атак. Это также устраняет риск хранения данных в нескольких изолированных точках хранения, которые могут подвергнуться спланированной скоординированной атаке, что могла бы привести к массовой потере пользовательских данных.

### Где купить Storj?

Так как токен Storj далеко не новое блокчейн решение, он может похвастаться хорошей ликвидностью. Более чем на пятидесяти обменных платформах $Storj котируется в парах с другими основными валютами и криптовалютами, включая Crypto.com и [Binance](https://coinmarketcap.com/ru/exchanges/binance/). А напрямую конвертировать его в доллары США и Евро можно на [Kraken](https://www.kraken.com/).

0x is an infrastructure protocol that allows users to easily trade ERC20 tokens and other assets on the many different blockchains (including Ethereum) without relying on centralized intermediaries. It is a protocol for decentralized exchange.

0x achieves this decentralized exchange functionality using a collection of open-source, publicly auditable smart contracts that work together to produce a flexible, low-friction trading protocol that developers can easily weave into their products.

The protocol is used by companies building web3 apps such as wallets, DEXes, portfolio trackes, and others. It is a used by hundreds of developers for their projects. The protocol has facilitates over $200B in trading volume since its inception. One can track its usage in its dedicated https://explorer.0x.org/.

The protocol is powered by an ERC20 governance token known as ZRX. ZRX holders can participate in protocol governance, having direct power over protocol changes and its community treasury.

0x Protocol

Launched in 2017, Livepeer is the first live video streaming network protocol that is fully decentralized. The platform aims to become a viable blockchain-based, economically efficient alternative to centralized broadcasting solutions for all new and existing broadcaster companies.

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

As stated in the official Livepeer whitepaper, the live video streaming and broadcasting industry is growing at a rapid pace, and the company is looking to ride this wave and introduce decentralization to the environment. Livepeer aims to streamline the broadcasting process by allowing producers to submit their work on the platform, taking care of reformatting and distributing the content to users and streaming platforms.

Livepeer

Band Protocol is a cross-chain data oracle platform that is able to take real-world data and supply it to on-chain applications, while also connecting APIs to smart-contracts to facilitate the exchange of information between on-chain and off-chain data sources.

By supplying reputable, verifiable real-world data to blockchains, Band Protocol unlocks a range of new use cases for developers to explore — since they can now use any type of real-world data as part of their decentralized application (DApp) logic, including sports, weather, random numbers, price feed data and more.

Band Protocol initially launched as an ERC-20 project on the Ethereum blockchain in September 2019, but transitioned to the Cosmos network in June 2020 with the release of Band Protocol 2.0. The new protocol is built on BandChain using the Cosmos SDK. Oracle nodes on BandChain not only relay data but are also involved in block production/validation, giving them a dual role.

BAND is the native token of the Band Protocol ecosystem and is used as collateral by validators involved in fulfilling data requests, as well as the main medium of exchange on BandChain — being used to paying for private data.

Band Protocol

SKALE, described as a modular blockchain network, is designed to bring scalability to Ethereum. SKALE is the only blockchain network capable of running an unlimited number of fast, on-demand, pooled-security Blockchains with zero gas fees to end users. These individual chains are known as SKALE chains and can be dapp-specific or shared.

The project’s website says it wants to enable people to build and run DApps in a “decentralized modular cloud built for real-world needs and configured for your requirements.” This emphasis on decentralization isn’t at the expense of security.

According to SKALE, those who build on this platform can run Solidity smart contracts “thousands of times faster at a fraction of the mainnet cost” — with games and content streaming services among the projects that already take advantage of its infrastructure.

SKALE

What Is Ankr (ANKR)?

Ankr

LRC is the Ethereum-based cryptocurrency token of Loopring, an open protocol designed for the building of decentralized crypto exchanges.

In 2020, the average daily trading volume of the entire cryptocurrency market fluctuated in the approximate range of $50-$200 million. Most of that trading is conducted on centralized cryptocurrency exchanges — online platforms operated by private companies that store users’ funds and facilitate the matching of buy and sell orders.

Such platforms have a number of downsides common to all of them, so a new type of exchange — decentralized— has emerged to try to alleviate these disadvantages. However, fully decentralized exchanges are not without their own flaws.

Loopring’s purported goal is to combine centralized order matching with decentralized on-blockchain order settlement into a hybridized product that will take the best aspects of both centralized and decentralized exchanges.

LRC tokens became available to the public during an initial coin offering (ICO) in August 2017, while the Loopring protocol was first deployed on Ethereum mainnet in December 2019.

Loopring

Siacoin (SC) is the native utility token of Sia, a blockchain-based distributed, decentralized cloud storage platform. Sia acts as a secure, trustless marketplace for cloud storage in which users can lease access to their unused storage space. Agreements and transactions are enforced with smart contracts, and Siacoin is the medium of exchange for paying for storage on the network. The main goal of the project is to become the "backbone storage layer of the internet."

Sia was originally announced in May 2014 before being revised and re-announced a year later in May 2015. It officially launched in June 2015.

Siacoin

Orchid (OXT) is the native token of Orchid, a cryptocurrency-powered virtual private network (VPN).

Launched in December 2019, Orchid describes itself as the world’s first incentivized, peer-to-peer privacy network.

Its aim is to overcome internet freedom limitations by using cryptocurrency payments to allow anyone to purchase bandwidth from any participating provider. This is done using so-called probabilistic nanopayments, which occur using OXT, an ERC-20 standard token on Ethereum.

Regular payments to providers occur off-chain, allowing Orchid to avoid problems with congestion and gas fees on the Ethereum network.

The service is pay-per-use, meaning that users only have to contribute funds when they actually connect, instead of paying monthly or annual fees.

Orchid

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

UMA was founded in 2018 by Allison Lu and Hart Lambur, two ex Goldman Sachs traders, with the goal of making global markets universally fair, accessible, secure and decentralized.

The team drew inspiration from traditional finance derivatives to define an open-source protocol to allow anyone, anywhere, to design and build trustless financial contracts.

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

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

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

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

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

Filecoin

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

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

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

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

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

Bancor

Audius is a decentralized music streaming protocol initially built on POA network, but now living on Solana. Audius was launched to remedy the inefficiencies of the music industry, which is plagued by intransparent music rights ownership and intermediaries standing between artists and their audience.

Audius aims to align the interests of artists, fans, and node operators through its platform powered by its native AUDIO token. Artists can upload music, stored and distributed by content and discovery nodes, that fans can listen to for free. Currently, Audius rewards content creators through rewards like featuring in the weekly trending lists. In the future, it plans to integrate stablecoins for artists to offer paid content, as well as artist tokens that give fans the ability to access exclusive content, potentially cooperating with platforms like Rally.

Audius

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.

Synthetix

Compound is a DeFi lending protocol that allows users to earn interest on their cryptocurrencies by depositing them into one of several pools supported by the platform.

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

When a user deposits tokens to a Compound pool, they receive cTokens in return. These cTokens represent the individual’s stake in the pool and can be used to redeem the underlying cryptocurrency initially deposited into the pool at any time. For example, by depositing ETH into a pool, you will receive cETH in return. Over time, the exchange rate of these cTokens to the underlying asset increases, which means you can redeem them for more of the underlying asset than you initially put in — this is how the interest is distributed.

On the flip side, borrowers can take a secured loan from any Compound pool by depositing collateral. The maximum loan-to-value (LTV) ratio varies based on the collateral asset, but currently ranges from 50 to 75%. The interest rate paid varies by borrowed asset and borrowers can face automatic liquidation if their collateral falls below a specific maintenance threshold.

Since the launch of the Compound mainnet in September 2018, the platform has skyrocketed in popularity, and recently passed more than $800 million in total locked value.

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.

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

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

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

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

The Graph

Balancer is an automated market maker (AMM) that was developed on the Ethereum blockchain and launched in March 2020. It was able to raise a $3M seed round by Placeholder and Accomplice. Balancer protocol functions as a self-balancing weighted portfolio, price sensor and liquidity provider. It allows users to earn profits through its recently introduced token ($BAL) by contributing to customizable liquidity pools.

To learn more about this project, check out our deep dive of Balancer(https://coinmarketcap.com/alexandria/article/what-is-balancer.

The protocol operates a few types of pools:

Private pools give the owner governance over the pool, and make the person the sole contributor of liquidity to the pool. Also, all the parameters are mutable by the owner.

Shared pools are for those who want to become liquidity providers (LPs). The LPs are rewarded with the Balancer Pool Tokens (BPTs).

Smart pools are similar to private pools but are controlled by a smart contract. They also reward using BPTs and allow anyone to contribute liquidity to the pool.

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.
