Arweave, a new era of storage
The web has evolved into an engine of inequity and division; swayed by powerful forces who use it for their own agendas.
Tim Berners-Lee 《One Small Step for the Web》
"Humanity's new weapon. Government censorship and technology giants' monopoly on data have made the Internet gradually deviate from Tim Berners-Lee's original vision of equality and freedom when he created the World Wide Web.
At the beginning of information communication, Cypherpunk realized the importance of personal privacy protection and data communication encapsulation and encryption. Driven by the spirit of geeks, emerging technologies such as the Internet encrypted transmission protocol SSL, digital currencies such as the World Wide Web, BitTorrent, and Bitcoin have sprung up, and they have begun to fight back against the oligopolistic enterprises that monopolize information. Data storage needs to be solved, in addition to ensuring data integrity and no loss, it is also necessary to ensure data privacy and no leakage. BitTorrentIn 2001, Bram Cohen proposed
(BT, BT download), a decentralized transmission solution based on the TCP/IP protocol. It changed the protocol transfer procedure from point-to-point to what is now referred to as peer-to-peer. As an open source content distribution protocol, BT itself uses peer-to-peer technology to share large-capacity files, such as movies/TV programs. Its application scenario can be said to be the prototype of a decentralized storage model. In 2008, Satoshi Nakamoto released the Bitcoin crackdown white paper, opening another era dictated by the cypherpunk spirit. The concepts of decentralization and anonymous settlement in the Bitcoin spirit combine the anonymity and privacy advocated and pursued by the cypherpunks. The spirit of Bitcoin has opened another era, a new era of digital currency, and an exploration leading to web3.And in it,Decentralized storage has become an important part of the foundation of Web 3, is the drive to empower individuals with data,Taking back personal digital sovereignty from the enterprisethe next future ofMessari 2022 Reports. As, Ryan Selkis at"
"Of the various components of the Web3 hardware stack, decentralized storage is arguably the most powerful.
Next, the article will talk about how Arweave completes a permanent and sustainable storage solution through unique technical advantages and effective economic incentives from three aspects: technology, economic model, and application prospects. The characteristics of tampering, writing content into blocks, how to resist censorship with the characteristics of decentralization, privacy, and anonymity, solve Internet privacy and data security, and build a future of equality, freedom and democracy.
TL;DR
first level title
From a technical perspective, Blockweave and Succinct Proof of Random Access (SPoRA) solve permanent storage of information, Wildfire encourages miners to read data; permaweb and the second-layer solution Bundlr provide a web2-like user experience.
In Arweave, the storage fee paid by the user is the permanent storage cost of the miner; the miner's income comes from network fees and block rewards; the donation pool will ensure that the miner's income can cover the cost.
AR tokens are similar to ETH and are utility tokens; but similar to BTC, AR adopts a continuous halving model, which makes it "coin holder friendly".
Arweave, which has permanent economic value, and the commercialized Filecoin are complementary and healthy competition. Arweave's various data indicators ushered in explosive growth when NFT exploded in 21 years.
The advantage of Arweave is not only to solve the permanence and immutability of data storage; from an abstract level, it is the necessity of the existence and flow of information, and it is the technical display of personal sovereignty consciousness in the cypherpunk spirit.

Part 1. Arweave's Technology WaveThe core of Arweave technology is to solve how to accomplish。
"Permanent and sustainable" storage
This article revolves around the following three points:
Blockweave and Succinct Proof of Random Access (SPoRA) are the underlying modules for permanent storage of information;
Permaweb and Bundles provide a web2-style user experience.
secondary title
Blockweave and SPoRA Consensus
The bottom layer of the Arweave data network is based on Blockweave's block generation model, which can be said to be an "advanced" Bitcoin network. A typical blockchain, such as Bitcoin, is a single-chain structure, i.e. each block will be linked to the previous block in the chain. In blockweave's network structure, each block will also be linked to a random recall block in the previous history of the blockchain on the basis of the previous block. Recalling blocks is determined by the hash value of the previous block in the block history and the height of the previous block, which is deterministic but unpredictable. When a miner wants to mine or verify a new block, the miner needs to have access to the information of the recalled block.
On the surface, Arweave is similar to Bitcoin in that: a series of blocks are encrypted together; miners are compensated from inflation and transaction fees; the consensus mechanism relies on Proof of Work (PoW). Arweave's consensus — Proof of access (PoA) is an extension of PoW (Proof of Work).PoA uses the RandomX hash algorithm,Probability of a miner to produce a block = Probability of randomly recalling a block * Probability of being the first to find a hash
. Miners need to find a suitable hash value through the PoW mechanism to generate a new block, but the random number (Nounce) depends on the previous block and any random memory block information. The randomness of recalling blocks encourages miners to store more blocks, thereby obtaining relatively high calculation success rates and block rewards. PoA also incentivizes miners to store "scarce blocks", that is, blocks that are not stored by others, to obtain greater probability and rewards of block generation.According to relevant calculations, the probability of Arweave network block loss is smaller than the probability of private key collision.
Wildfire

A one-time fee means that subsequent data reading is a free service, and sustainability means that users can access data at any time. So how to motivate miners to provide data reading services with zero income in the long run?In BitTorrent's game theory strategy "optimistic tit-for-tat algorithm" design, nodes are optimistic and will cooperate with other nodes, and non-cooperative behavior will be punished. Based on this, Arweave designedWildfire, a node scoring system with implicit incentives
. Each node in the Arweave network will score adjacent nodes according to the amount of data received and response speed, and the node will give priority to sending requests to peers with higher rankings. The higher the node ranking, the higher its credit, the greater the probability of producing blocks, and the greater the possibility of obtaining scarce blocks.
Similar to BitTorrent, nodes are occasionally "optimistic", choosing to interact regardless of node rank. Under the Nash equilibrium strategy, nodes expand from simple bandwidth sharing to pro-social behavior of freely sharing resources, cooperation is greater than competition, and the efficiency of data sharing between nodes is also improved., is a highly scalable game. There is no "ranking" consensus between nodes, and there is no obligation to report the generation and determination of rankings, and the "good and evil" among nodes is adjusted by an adaptive mechanism to determine the rewards and punishments for new behaviors. In March 2021, nodes in the Arweave network discovered that another group of nodes used pooling software that was not conducive to maximizing data replication; subsequently, another group of miners modified and lowered their ranking scores for these miners to prevent them from Continue to do evil and maintain network stability.

Permaweb and BundlesLooking at the protocol architecture,
Responsible for the general data consensus and sharing layer is the underlying data storage protocol — the arweave network layer, and above this is the permaweb (permanent network).
Always in the network is a cluster of communication protocols (a cluster of communication protocols), the core function is low-cost, zero-maintenance, permanent storage of information, including text, video, and even dApp. Just like the HTTP protocol used by the Internet is based on TCP/IP, the always-on network based on arweave can be understood as being based on the HTTP protocol.EvermoreFrom a user perspective, users only need to upload data through dApp. For example, ArDrive, a permanent version of Dropbox, uploads data to Always On. desktop
Then allow the user to configure a local folder, and the contents of the folder will be automatically backed up to Arweave. These dApps enable Yongzai.com to provide a user experience similar to that of the traditional Internet, but the content posted by users can be permanently accessed and used, and 404 will not appear.Arweave's own smart contract standard SmartWeave uses Javascript to build smart contract applications. SmartWeave is different from other smart contracts, SmartWeave uses the "lazy evaluation
"system (lazy evaluation). It allows the blockchain to exempt gas fees, and the transaction verification of the smart contract is downloaded to the local client for execution by the contract caller (ie the user) on the basis of trust, rather than the miner node in the network .Deployment and interaction costs of the network are lower as the burden of contract execution is shifted from nodes in the network to clients/users.BundlrIn September 2021, Arweave released a Layer 2 solution—Bundlr delivers a Web 2-like speed and productivity user experience without sacrificing security。
at present,at present,. Intuitive data shows that Bundles provide more reliable and cost-effective permanent storage, and also attract more developers and users into the AR ecosystem.

Part 2. Economic Benefits of Arweave
The success of a protocol is often driven by the liquidity that participants bring. Under the effective token model, participants are bound to the interests of the agreement, and sustainable income attracts participants to enter. In general, participants can be divided into two categories: miners/stakers, and users. In the Arweave economic model, the native token AR has two main uses:
1) Transaction fees: Users who wish to put data into the storage network pay storage fees with AR tokens;
2) Miner rewards: Miners are rewarded for mining, that is, storage, data retrieval and other services.
Arweave's claim of permanent storage relies on economic guarantees, so Arweave's reward mechanism is an important part of continuously motivating miners to participate in Arweave's ecological construction. The supply and demand model of the Arweave ecosystem is as follows:
Demand = user storage
The price elasticity of Arweave demand is difficult to confirm, but Arweave is actually a "free" market. Over time, the storage fees/costs paid by users tend to approach miners' costs and the profits they generate.
secondary title
storage cost
storage cost
The storage cost of any data on Arweave depends on three factors:
the size of the data being stored
The legal cost of permanently storing 1 GB of data today
Fiat price for AR (Arweave's native token)The premise of all this is based on the trend of decreasing storage costs of Internet networks. Storage costs are mainly affected byData Density and Data Reliabilitydrive.Unlike Moore's Law, which slows down the CPU, the maximum density of current hardware data storage is much lower than the theoretical calculation value.Therefore, Arweave's calculation assumptions are more conservative**, and the starting price of 1GB/hour of hard disk storage in the market will be, rather than the average annual decline in data storage costs of 30.5% over the past 50 years.
have to be aware of is,have to be aware of is,Storage fees paid by users are also set as the cost of permanent storage for miners, Arweave's current charges are sufficient to coverStore data for 200 yearsArweavefeesthe cost of. according to
Data, the current cost of storing data is about 2.927 USD/GB.The storage price is paid by AR tokens. As the demand for storage on the Arweave protocol increases, the value of the AR token will also increase. When the AR token fluctuates, Arweave will automatically call(dynamic storage price stabilization mechanism) to ensure that the data cost on Arweave is stable in fiat currency. Under this mechanism, the AR rewards for miners mining are proportional to the mining difficulty (Network Difficulty), and the inflation rewards (Inflation Rewards) are inversely proportional. Although this mechanism cannot prevent the fluctuation of AR price, it is an excellent anti-fluctuation mechanism in the long run.
Dynamic storage price adjustment model formula
secondary title
Miner incomeThe core contributors to the Arweave network are voluntary miners. The incentive for miners to permanently store data is revenue. There are two main sources of income for miners, one isNetwork Fee, the other is。
Block Reward/Block InflationThe income from network fees comes from 14% of user fees, and these tokens will also directly become circulation. The remaining 86% will go to the endowment pool,。
When the cost of miners cannot be covered, the funds in the donation pool will be distributed to miners as subsidiesThe endowment fund is similar to bank deposits, which will reduce the liquidity of the token secondary market in a short period of time and will continue to generate income. Arweave network storage capacity (weave size) is highly positively correlated with donation pool funds. Also, in Arweave,The block reward follows the algorithm design in a continuous halving mode
(continuously halves its issuance rate), not affected by external factors. With the passage of time, the storage cost of Arweave has decreased year by year, and the block reward has also decreased year by year; but with the increase of weave size, the accumulation of AR in the donation pool will be enough to subsidize the cost of miners and ensure income. This is also the economic backing for Arweave to ensure data storage for at least 200 years.In summary, block inflation is the most basic source of income for most encryption protocols. For example, Bitcoin and Ethereum provide miners with block verification compensation in the form of native tokens. The total amount of AR is 66 million, and 55 million were generated in the genesis block on June 8, 2018.Similar to Bitcoin, AR token issuance/block reward design is on the decline. Unlike Bitcoin’s discrete halving model that halves every 4 years,。AR token is a continuous halving modelAs reported by Delphi Digital
In 2021, block rewards accounted for approximately 972,000 AR, which is an average of 3.7 AR/2 minute blocks; as the block inflation finally reached 0, AR tokens finally completed the issuance of 66 million tokens.On the other hand, AR is similar to ETH in that it isutility token(utility token). It is mainly used in two aspects, one is for users to pay storage fees; the other is as a block reward for miners. As the demand for Arweave storage increases, the "utility" value of AR tokens increases, and because a large proportion of AR tokens in transaction fees will be deposited into the donation pool, the circulation of AR will instead decrease. likeTeacher Liu Yi's article
Arweave ecological investors (that is, AR holders) are not the promoters of the ecosystem, but passive holders. Holders cannot obtain certain rewards by paying money supply, that is, by staking. Arweave currently launched Wrapped AR (wAR), which provides more possibilities for Arweave token holders and ecosystem builders. wAR is linked to AR at 1:1 and is an ERC20 token. Users extract AR to the Ethereum network on Arweave's DEX — everpay to obtain WAR, which can then be traded in the Ethereum dApp ecosystem. For example, in December 21, Uniswap V3 launched the wAR/ETH liquidity pool, providing a way to passively make money by holding AR.
Part 3. Arweave, present and future
secondary title
1. The positioning of the decentralized storage track
From the perspective of the decentralized storage track, Filecoin and Arweave are the two core competitors of the track. There are many detailed articles comparing the differences between the two; this article does not elaborate on the differences between the two.Simply put,Filecoin is more "commercial". FIlecoin, which is more like the economic layer of IPFS, allows individuals to use idle hard disk and bandwidth capacity for data storage; pay-as-you-go charging model, it is more like the decentralized version of AWS and Google Cloud. andThe economic value of Arweave is permanent, with game theory design, one-time fee model and other incentives to bring a premium to permanent storage. Filecoin meets user needs with thousands of contracts based on requirements such as price, duration, and number of copies; while the Arweave platform actually only provides one contract: permanent storage of data. The most similar value proposition to Arweave is IPFS, but files stored on IPFS can still be deleted. For example, Infura's IPFS pinning service。

2. Arweave data performance
This article willThis article willTransaction volume, data usage, total storage, and protocol revenue
These four data are used as the core indicators for evaluating Arweave storage requirements.
Overall, since the mainnet launch in June 2018, Arweave has been gradually accepted by public chains and NFTs as one of the solutions for data storage in the Web 3 world. Various data indicators have gradually increased, but they have always fluctuated slightly and are lukewarm. in a state of ascent. Until 2021, NFT is hot out of the circle. Benefiting from the blowout demand of the NFT track, Arweave's various data indicators have begun to grow explosively, which also shows that in a certain sense, the storage demand of Web 3 at this stage determines the development possibility of Arweave.Due to market conditions and other factors, Arweave'simage description

3. The moat built by partners and application ecology
The core of the Arweave network is a database, more like a Layer 0, which is the basic building block of the network world; as the application layer, Permaweb is responsible for realizing NFT storage and transactions, traffic monetization, interactive monetization and other scenarios, bringing Arweave higher market fit.According to Verto Exchange data, in October 2021, there are only 35 DApps built using Arweave storage,。After only 3 months, it has risen to about 65Ecological projects cover tracks such as NFT, DeFi, wallets, and storage, but most of them still focus on infrastructure.
Each track has at least one representative project, such as ArDrive (storage), ArConnect (wallet/identity), Pianity (music NFT), EverPay (DEX), etc.PermaswapOn May 16, 2022, the official website and white paper were released to fill the gap in the cross-chain DeFi of Arweave ecology.

Arweave's application distribution, image source:Arweave is also available via theProfit Sharing CommunitiesOpen Web Foundryandand other measures to motivate developers; the former gives developers and contributors more rights and benefits to the project, and the latter provides support for incubation projects. can be seen,
Arweave is moving from a single decentralized, permanent storage solution to an integrated, DApp-accommodating Layer 1 ecosystem.It is undeniable that the thinness of Arweave's application ecosystem and the absence of users are problems that need to be solved urgently. But as a more "technical flow" underlying chain, DApp cannot be the only condition for evaluating the development of Arweave. asForesight Research points out", "Arweave Developers'"，"Storage-Based Consensus Computing"and"and"Arweave as Turing Machine Tape"In fact, developers have gradually reached a consensus, so more and more project ecology are using Smartweave to implement"Frontend = Smart Contract
design ideas. "From another perspective, although the Arweave smart contract still has a long way to go to attract high user traffic; its internal storage consensus is a magic weapon to enhance the plasticity of market demand. Arweave's
Market demand first comes from the ever-growing crypto ecosystem needs, including cooperative public chains, Web 3 creator economies, and decentralized censorship resistance.
1) A cooperative public chain has been established
Through the middleware Kyve, Arweave has become the storage backend of multiple public chains including Solana, Avalanche, Near, and Cosoms.
Unlike Bundlr, which focuses on data uploads, Kyve itself does not actually store any data, and is only responsible for data verification. Bundlr and Kyve complement each other. The way Bundlr packaged transactions aided the development of Kyve. Unlike other scaling solutions, Bundlr publishes the aggregated data into uncompressed weave, which ensures that Kyve can also easily retrieve the data in the packet it was collected and stored in. Bundlr seeks to handle the ever-increasing transaction throughput, while Kyve seeks to solve data retrieval and data validity issues, which allows Arweave to operate in a balanced manner in the event of ecological expansion and surge in data storage.
2) Web3 Creator EconomyFor cost considerations, NFT smart contracts usually store the actual content in a simple Token URI, and most URIs do not guarantee the "permanence" of NFT. For example, the World of Women NFT project makes its；nft.storageImage files are stored on Amazon Web ServicesStoring data on IPFS, however, itsHowever, it stated that "the data will be stored indefinitely through automatic update storage or other means, or until the nature of the service provided by Protocol Labs for NFT.storage ceases/changes."
“Data will be stored on the Service indefinitely through auto-renewal of storage deals or equivalent means….In the unlikely event of cessation or change in the nature of the Service, existing Filecoin storage deals will continue until their designated end date, and Protocol Labs will…” — NFT.storage 《Service Term》
textArweave is becoming the preferred NFT storage solution, and the first factor to "break the circle" is the NFT wave in 2021. The top NFTs in the Solana NFT ecosystem, such as Degenerate Ape Academy, Solana Monkey Business, etc., are all stored on Arweave, the default choice. More and more artists and creators choose Arweave as the storage platform for NFT works, including Christie's auction house with 6934NFT sold for $10,000digital artistBeeple chooses to launch NFT platform WE.NEW on ArweaveJay-Z; American rapperin collaboration with artist Derrick Adams《Heir to the Throne, 2021》The first NFTStored on Arweave
, and finally sold at Sotheby's for $138,600.But NFT works are far more than JPEGs,，Text authoring platforms like MirrorMusic NFT platforms like Pianity and Releap
Both also store data on Arweave. The advantages of Arweave's decentralization, content permanence and immutability are underpinning the NFT and Web3 creator economy.In addition, in addition to solving the problems of NFT storage, data persistence and even smart contracts, in order to better integrate major NFT markets such as Opensea, link NFT on Arweave to other chains,Atomic NFT。
Koii Network Introduces a More Reliable, Cheaper, and Time-Saving NFT Standard -Koii.rockAtomic NFT is a single Arweave transaction that includes asset files, metadata files, and smart contracts. Atomic NFTs are stored in the state of the SmartWeave contract. Each NFT corresponds to metadata including owner, title, artist name, description, etc., and the code is able to perform its function. Since Atomic NFTs use a common standard, they can be exchanged across all compatible applications, public chains or formats such as Ethereum (/EVM), Tezos and Polkadot. This makes NFT another "data format" to participate in the sharing economy in Arweave. Community-made Atomic NFTs are currently available at
Browse the leaderboards.
3) Anti-censorship of DeFiThe inner consciousness of the DeFi economy comes from "decentralization", hoping to create a more equal, more transparent, and safer digital economy. However, DeFi projects such as Uniswap cannot escape supervision. In July 2021, due to US regulatory policies, Uniswap registered in the USAnnouncement statement, which will be removed from the front end from derivative platforms such as Synthetix129 tokenized stocks
. Although the transaction records on the Ethereum chain cannot be modified, although the front-end user interface (UI) is open source, and although the smart contract under the UI interface still exists, the management of the UI is still centralized, and developers have the right to modify the UI interface. Any changes and "updates".As proposed by Arweave,"Protocols Are Forever, But Can DeFi Be Censored?"When decentralized finance loses its decentralized nature and becomes a victim of regulatory policies, it leaves a dystopian shadow. Arweave became an answer. When Arweave hosts a copy of the DeFi frontend, the data becomes censorship-resistant, permanent, and immutable. A "permanent" memory in the Internet age may mean less threat of government censorship. In response,User uploaded on ArweavePrevious version of UniswapSushiSwap、Compound, for easy user access review. Uncensored versions of other DEXs such aspermaweb, 1inch, Synthetix, etc. are all available in Arweave
Check it out.
Of course, although the original version information stored on Arweave will not be overwritten, it cannot be changed in any way by anyone, neither the user nor the project developer. But for smart contracts, permanence also means high costs for project upgrades. If the project wants to upgrade the version, even minor front-end changes need to be deployed with a complete new version.
4) Business needs in society
As Arweave's developer ecosystem continues to grow and capture new crypto trends, more crypto use cases are being spawned. On the other hand, the commercial needs of Arweave in society are much more than imagined.
In simple terms, Arweave's social data storage is suitable for the following aspects:；
Legally binding documents such as contracts, court rulings and opinionsIn 2014 Harvard Legal Studies
found that about 50 percent of links in Supreme Court cases no longer work. The authors also found that 70% of links in legal journals no longer worked as expected.Large organizations that permanently store large amounts of information
, including government/non-governmental organizations/foundations, etc.;For example, on Permacast reserved21 American History Lectures16 GB;Currently, the audio content uploaded to Permacast reaches
about.political censorship
: Dissident political views propagated by the government are often deleted in the form of eliminating voices against the present and obliterating the imprint of history, while permanent storage protects the channel for the occurrence of personal sovereignty consciousness;Hong Kong Democracy Daily；

3. The next future of ArweaveAllied Market Researchsource:

source:When humans become accustomed to using the Internet to retrieve information and enter the door of knowledge payment, they find that data loss, data impermanence and centralization risks,Internet memory is not forever. Over the past 20 years,；More than 100 scientific open access journals disappear from the internetAccording to Arcast
, 95% of the data that came from the Internet 20 years ago no longer exists.The purpose of the Arweave protocol is to solve the permanence and immutability of data storage.
Arweave technology ensures the feasibility of the project, and the game theory design is an economic means of long-term incentives. But in addition to a long-term and effective incentive plan, the Arweave ecology also needs the next strong catalyst, whether it is Gamefi or Metaverse, or the widespread adoption and acceptance of Web 2 cases. Price has never been Arweave's game, its technological innovation and pricing model are how it differentiates itself from its competitors. AR tokens are not designed for investors, but with the development of the network, token price appreciation is inevitable. The donation pool structure creates a "third" source of income for miners, and the dynamic balance of supply and demand ensures the long-term sustainability of the protocol.
Compared with Web 2, Web3 network is a modular architecture. It can be simply understood that the front-end data can be stored in a decentralized storage network; while the back-end server is based on smart contracts. From the perspective of the entire Web3 ecology, Arweave is a big backend that empowers the development of Web3 through Permaweb, including the storage of NFT and blockchain historical data. What Arweave can break in the future is the public's inherent impression of the feature of "permanent storage".Of course, not all data is worth and should be stored. In Arweave, nodes are not forced to store any data, and miners can choose any blocks and transactions they think are worth or want to store. SuchThe content review system (Content Policies) is anti-censorship, more like a decentralization of power, and the right to choose content returns to the hands of the "people"
. On an abstract level, Arweave offers a more democratic solution that avoids the Orwellian memory hole and mitigates the impact of "fake news" in black swan events.
Behind the value of Arweave is a romantic story. Its birth combines the spirit of cypherpunk, and it is a reappearance of personal sovereignty consciousness on the technical side. Under digital totalitarianism, freedom and privacy are precious. Humans are afraid of 1984 and try to build an eternal "Alexander Library". Although libraries and the Internet are prone to decline and loss, archiving services point to the availability of knowledge and the mobility of the Internet. Arweave solves not only the long-term validity of data storage, but also the value of long-term captured information, as well as the functionality and mobility of the Internet.
