Note: Some items can be grouped into different categories, but this article categorizes them in their main direction.

0、Basic Info

Arweave is a block network whose core service is to provide distributed permanent storage of data. It aims to be the new 'Alexander library' of the world for the Web3 era. In addition to storage, on top of AR's underlying network, there's an application layer called permaweb, and the Smartweave smart contract system, which enables apps and smart contracts to run. In that sense,Arweave can also be seen as Web3.0, including the app ecosystem smart contract system and storage protocol. According to ArweaveApps' data, the number of Arweave applications included has reached 411, some of which are native applications based on Arweave. The following table lists the classification and official website of these applications

1、NFT

Pianity

Pianity is an emerging music NFT trading platform that can help creators to change their music works to NFT form and sell them to generate continuous income. Through Pianity, musicians and their communities can create, sell, buy, and collect limited-edition tracks, authenticated via the blockchain. By returning the status of art to music, Pianity provides artists with a new source of income, allowing them to be more independent and live better from their passions. Every token registered to the Pianity protocol is provably unique. Rather than creating artificial scarcity by selling copies of digital goods (like Bandcamp), Pianity offers an alternative: make an original publicly available to everyone, no matter who owns it, and sell that original token repeatedly.

Pianity provides 4 art versions, divided based on the number of NFTs, each version has different scarcity,

• Unique Limited Edition: A one-off digital music with only 1 NFT available.

• Legendary Limited Edition: Only 10 NFTs to choose from.

• Epic Limited Edition: Only 100 NFTs to choose from.

• Rare Limited Edition: Only 1000 NFTs to choose from

Darkblock

Darkblock is a control panel for decentralized content. Its protocol layer (PerM: Personal Rights Management) allows users as creators to choose how to distribute, display, sell, rent, hide, destroy or unlock NFTs. Users can determine slice ownership, royalty structures, and inherent properties while ensuring their creations are not copied, distributed, or used beyond their intended purpose.

With Darkblock, "limited edition" artwork now has the same meaning in the digital space as it does in the physical world. Darkblock's decentralized encryption technology allows digital artists to control access to their original works, so they can finally bring unique, protected high-resolution content to the world as NFTs. For the collector, this means the true uniqueness of the items he owns, higher resolution, and giving him 100% exclusive ownership of the purchased content. Darkblock provides intrinsic value to NFT content through exclusivity. Using Darkblock and partner apps, owners can decrypt their exclusive digital content and display it on any compatible screen, showcasing artwork in the living room, collectibles on mobile, high-resolution original video content on TV.

Mintbase

Mintbase is the top minting platform for various NFTs. Mintbase has integrated with Arweave to use the network as a storage layer for media and metadata, a key part of its NFTs: making them fully on-chain and permanent. The public can mint, sell, and develop NFTs on their own smart contracts. The main point of difference for Mintbase is that it offers NFTs that are not commonly found on other platforms. For example, Mintbase covers niche NFT categories such as music, memberships, services, tickets, news, and photography. Features of Mintbase are:

• Based on the NFT trading market, the NFT market has huge potential. For example, Epic Games made $2.4 billion in revenue from selling in-game clothing in its free-to-play game "Fortnite" in 2018 alone, but users are trying to sell a Fortnite clothing item on eBay, which is currently very difficult, and NFT transactions will cut in This potential area, change this market.

• Know how to differentiate competition. Compared with the competitor Opensea, it has its own uniqueness. Mintbase offers NFTs not commonly found on other platforms, such as music, memberships, services, tickets, news, and photography.

• Focus on user experience, which is conducive to attracting ordinary users to enter the NFT ecosystem. Mintbase provides Minting tools to make it easy for ordinary users to create their own NFTs and mass-produce them.

• Product decentralization. Users can deploy their own smart contracts to create stores; Mintbase's entire Ui is driven by TheGraph on IPFS, which records purchases, transfers, burns, and minting events when users interact with the blockchain.

• Use NEAR public chain sharding technology for expansion. Currently deploying contracts on Mintbase, creating stores, minting NFT tokens and other operations will consume very expensive handling fees. Mintbase will use the sharding technology of the NEAR public chain to reduce handling fees and increase transaction speed, which is conducive to attracting new users and traffic. Enter the NFT field.

Machi X

Machi X is a product copyright trading platform. After the creators pass the official review and certification, they can sell the copyright of their works on the Machi X platform. Their works can be in various art forms such as music and paintings. And its fans can buy part of the copyright rights on the platform and enjoy specific benefits. In other words, buyers can become shareholders of creators. At present, Machi X is the first to introduce three major functions to enhance creators' protection of work ownership, strengthen liquidity, and socialize investment to drive innovation and development:

• Copyright tokenization. Music, art, literature, inventions, designs are all valuable assets that have not been publicly traded in the past. Machi X is committed to creating a blockchain copyright exchange that feeds back creators: enabling creators to issue their own copyright tokens. Allow users who value copyright to support creators by investing in copyright tokens.

• A new type of copyright contract. Machi X provides a copyright contract service that is easy to understand, highly convenient and can be used immediately. There is no need to go through layers of channels or brokerage companies. As long as copyright owners with a fixed fan base, they can cooperate with Machi X to turn their works into The "Copyright Token" is listed on Machi X: if the copyright owner is a singer, the holder of the token can listen to works such as new songs that have not been released publicly. The creator promises that in the future, part of the proceeds will be used to buy back and destroy the copyright token, so as to increase the market value of this token and feedback this token holder.

• Invest in socialization and discover investment opportunities. Like art lovers and investors, when they want to explore treasures, art lovers will choose to invest in art galleries to find masterpieces. There are creators and creative works in various countries and forms on the Machi X platform, and fans with artistic vision can filter and interact with the creators.

2、infrastructure

3EM

3EM is a multi-language smart contract platform, users can use their familiar programming languages to build smart contracts. 3EM is mainly to solve the three major problems faced by traditional smart contracts, namely: speed, security and multi-language support. It mainly has the following four characteristics:

• Sandboxed：A fully secure & modern runtime for smart contract evaluation using isolated environments where malicious code cannot be evaluated.

• Deterministic：3em execution is deterministic. Random operations have a constant seed and Non deterministic APIs are overriden with their deterministic version. You can read more about it in our technical guide.

• SmartWeave Compatible：3em follows the SmartWeave contract design. This essentially means two things: 1）Contracts need to be deployed to Arweave in order for 3EM to run them，2）3em is capable of running existing Smartweave contracts and exposes backward compatible APIs (like the smartweave global).

• CLI and Library：Not only for users but for developers, 3em prioritized codebase to be used as an external library for JS, WASM, and Rust applications.

Koii

Koi is a network that deliberately works slow— not fast— making it possible to use distributed ledgers for a range of high volume activities that can form the foundation of a more open and transparent information infrastructure. The Koi Network provides a suite of software tools and cryptographic value channels that allow anyone to build tokenized protocols and reward participants, not only by mining new blocks, but by also cultivating attention and reputation. Koi operates similarly to a Layer 1 blockchain and manages internal consensus using a stake-based approach; it anchors to other blockchains, and primarily the Arweave permaweb for block storage to keep nodes lightweight (allowing highly scalable consensus) while ensuring long term transparency.

Kwil

Kwil is a decentralized SQL database that is a plug-and-play solution for developers to quickly build inexpensive, scalable and custom queryable applications on Permaweb. On KwilDB, data is stored in a relational database that can be queried using SQL. SQL has been in use since 1979 and is considered the standard language for querying database data. Almost every developer has used SQL at some point, which makes using KwilDB feel native to Web2 developers. The high scalability of KwilDB is achieved through the combination of Web2 tools and Arweave. Instead of reinventing the wheel, Kwil created a Web2 database synchronization protocol that enables powerful Web2 products on top of Web3 infrastructure. By normalizing data using SQL, developers can easily access data from other dApps in their own unique way through simple SQL statements. This allows dApps to extract other data without changing their own data structures, enabling an extremely high level of composability. KwilDB also allows for the easy implementation of sophisticated machine learning and content management engines. Because KwilDB leverages the way Web2 stores data natively, Web2 machine learning algorithms can run against Web3 data without any additional compatibility.

Amplify

Amplify is a new and revolutionary way to upload and download data from Arweave nodes using existing bandwidth. Users can run Amplify gateways on-premises or in the cloud and immediately start sharing their bandwidth. Users can also use the Amplify SDK to access data from Arweave using the Amplify network. It has two characteristics:

• A trustless peer-to-peer protocol: Amplify is a completely trustless consensus protocol. Each Amplify node has probe nodes to test and query its peers. Consensus is achieved when all nodes are working properly and outputting data correctly. If a node outputs incorrect data, it will be booted from the Amplify network and the node's token will be distributed to other nodes on the network.

• Access to Permaweb's SDK: Amplify provides users with the most efficient and easy way to access Arweave. Users can use Amplify SDK to access any content on permaweb. The SDK also makes it easy for users to find Amplify nodes in specific locations or places that aren't overloaded with traffic. This ensures that users have a good experience when querying permanweb data with few problems. CommunityXYZ

CommunityXYZ is a decentralized dashboard and governance platform dedicated to profit-sharing community projects. Project founders can create and manage communities on CommunityXYZ, issue specific tasks that provide PST token rewards, and potential contributors can claim and complete tasks Get paid. CommunityXYZ's smart contract is a standard implementation of Smartweave. It uses TypeScript (equivalent to an extended version of JavaScript). It contains the user's balance, vault, role, voting status and other information through a JSON-like data structure. At the same time, the contract also The necessary functions such as Transfer, increaseVault, and balance check are implemented. The SmartWeave contract implemented by CommunityXYZ can be placed in the front-end page code base, so that the contract logic can be stored in the front-end.

Meson Network

Meson Network is a next-generation storage (file) acceleration network based on blockchain Layer 2. It aggregates idle servers in the form of mining, schedules bandwidth resources and serves them in the file and streaming media acceleration market, including traditional websites, videos, live broadcasts and blockchain storage solutions. Meson decouples the two parts of storage and data reading, and builds a low-cost commercial file cache layer on the storage public chain of Layer 1, which enables blockchain storage to be applied to real real Business Environment. As a decentralized distributed CDN infrastructure, the market size is 23 billion US dollars, and the growth rate is relatively fast, and a large amount of server bandwidth is idle around the world. Compared with the complexity of computing resources, bandwidth is relatively easy to standardize, and the market has a huge demand for acceleration services that utilize bandwidth. Based on this, we propose a "meson network" that enables miners to participate using a common server based on blockchain technology. By letting users use common, idle servers, Meson removes barriers to mining while reducing the cost for businesses to use accelerated services.

• meson advantages: increase access speed, reduce network costs

• Problems solved by meson: breaking monopoly, saving costs, reaching long-tail users

ArGo

Argo, the premier open source GitOps and MLOps CNCF project, is a git-based web hosting platform that helps users build modern websites on Arweave permaweb. It aims to enhance the serverless web deployment market and beat current solutions by providing users with a scalable, user-friendly and reliable system for creating and deploying decentralized applications, websites and platforms. ArGo's development vision is to establish true permanence on the Internet without any censorship. Websites, applications and platforms built on ArGo will be fully decentralized, and the low cost involved will free users from the many drawbacks of expensive centralized solutions, saving them web server hosting costs, security and Database costs, etc. Instead, with ArGo, users will be charged a one-time deployment fee, which will buy them the permanence of their online data and allow them to put their business or ideas on the internet without having to lose them.

3、Storage

Kyve

KYVE is a blockchain storage middleware built on Arweave. With its standardized verification and filing framework, it can provide a unified solution for all blockchain data needs. According to the KYVE team, the project hopes to help various blockchain projects achieve convenient and permanent storage and reading of data on the chain, and does not require customization and development work, thereby helping Web 3.0 projects achieve unlimited scalability. Since the current blockchain infrastructure is still very imperfect, especially in terms of block data retrieval, retrieving a large amount of data on the chain is a heavy task that requires strong computing power and a long time. For example, syncing a full node on Ethereum takes a long time because the entire transaction history needs to be recalculated. There is currently no mature project that can provide flexible and structured data access services on different blockchains without custom development work, so a unified solution is needed to solve data storage and reading problems. This is the pain point that needs to be solved in the middle of blockchain storage like KYVE. The main functions of KYVE are:

• Fix Arweave scaling issue

• Upload and validate data through a standardized framework

• Realize data cross-chain storage

ArDrive

ArDrive is a permanent storage platform whose applications and core libraries provide hierarchical organization, privacy, flexibility, scalability, and access control to the most valuable data with full end-to-end encryption, all thanks to Its underlying core technology is the Arweave File System (ArFS) protocol.

Mirror

Mirror is a decentralized content publishing platform, which can be understood as a decentralized web3 platform for creators to realize the closed-loop editing, publishing, dissemination and commercialization of works. Founded by former Andreessen Horowitz crypto partner Denis Nazarov, similar to Medium, it helps creators crowdfund by providing creators with a token issuance tool. The core innovation of Mirror is that, combined with the ownership economic model constructed by DAO, Web3, and NFT, it provides a set of crowdfunding tools for content creators to solve the problem that creators cannot make money and realize the value of content. Not only that, early investors can even earn the future benefits of content through their keen sense of smell. Mirror is not just decentralized, but has integrated crypto-native currencies since the beginning and gives creators more control and ownership by tying digital identities. These characteristics allow Mirror to have multiple attributes of digital native information carriers that many Internet applications lack since its birth, including programmability, interoperability, composability, virus dissemination and transferability, and then realize its value exchange. possible.

Orbis

Orbis is an encrypted native social network based on Ceramic and Arweave, which can be understood as a decentralized version of Twitter. Anyone with an Ethereum address can create their own decentralized ID and share posts without paying any transaction fees. More importantly, all user data such as posts and chat contents are owned by the user, and the platform has no right to use it, and the user can package the data into other applications to open and use. Its features are:

• Prove a user owns an NFT or token

• Verify that a user used a DeFi protocol

• Create encryption rules based on on-chain data via LitProtocol, ex: only punk owners can decrypt this post, join a group...

6、DAO

ARCA DAO

The ARCA DAO is a DAO within the Arweave network that operates independently with members drawn from long-term miners, developers, and supporters of the Arweave community, with the goal of coordinating, planning, and distributing funds for projects and initiatives that benefit the Arweave community in the long run.

Builder DAO

Builder DAO is a community to build a better internet, together. Its mission is to help builders create the future of the Web. Builder DAO plan to execute on that mission by building a learning platform. DAO members will be able to propose tutorial guides and get feedback before publishing them. Writers and reviewers will be rewarded for the content they produce. And anyone with an internet connection will be able to access the guides and collaborate with other members to build.

This is a huge problem space and we fully expect Builder DAO to grow its membership, partner with others, and inspire more solutions. For instance, there’s a need for better documentation and Q&A databases. Maybe the community will vote to build a product that addresses one of these. Or maybe Builder DAO will spawn a subDAO for it. Or better yet, a team of members will choose to collaborate on a solution.
