Pay Once, Store Your Data on the Blockchain for Over 100 Years

That's what Arweave (previously known as Archain) is trying to do. And unlike Dropbox or AWS, you don't pay a monthly fee. You buy once, store for generations, and never pay for that storage again, ever.

Sounds good, isn't it?

But is that really necessary? Yes! To know why, let's take a look at digital data  — an area that has seen meteoric growth in the past decade or so.

Every second, approximately 8,000 tweets are tweeted; more than 70,000 Google queries are searched; and more than 2.5 million emails are sent. These activities continuously drive the explosive data growth and show no signs of slowing down.

Considering the trends above, we're working with 16.3 zettabytes of data a year today and IDC predicted that amount will rise tenfold, to 163 zettabytes by the year 2025.

If we look at the storage supply vs. demand…

By 2020, demand for capacity will outstrip production by 6 zettabytes, or nearly double the demand of 2013 alone. We're not just in the Zettabyte Era. Soon, we'll be in the "Unavailable" Zettabyte Era. And when demand is growing faster than supply, price will definitely soar.

The only affordable way out  — Decentralization

Instead of relying on expensive centralized silos (owned by for-profit businesses) to store data, we can distribute data across a vast network of peers who are paid to store each other's data.

The iCloud hack of 2014 and the Dropbox hack of 2012 also motivated this trend of decentralization, which promises a trustless secure network that is much faster and censorship resistant.

By decentralizing storage, individuals can monetize their unused storage space and businesses can abstract away the potential bottlenecks that prevent new innovative uses of data. This influx of supply into the global storage market will also drive down storage prices, making it more affordable.

Recent years, we've seen many decentralized solutions joining the race to disrupt this data storage industry. Storj, Sia, Filecoin and Bluzelle, all trying to compete for market share.

…so what sets Arweave apart from other decentralized storage solutions?

Scalability and Affordability. As we continue to generate countless zettabytes of data, the question of where and how to store it becomes increasingly important. We need something that's easy to use, sustainable, cheap and still considerably fast in data writing and recall.

5,000 transactions per second is what Arweave promises for data operations on a 100 mbps network. Most competitors can't even come close! Storj and Swarm on Ethereum, are stuck with 15 transactions per seconds until Plasma becomes a reality. Filecoin and Sia rely on data hosts to provide the required performance for better rewards via storage contracts. MaidSafe works on a new non-blockchain consensus that focuses more on fault tolerance over efficiency.

Besides, most other solutions require either a monthly subscription or payment based on data size. Arweave only requires one-time payment for a lifetime access of unlimited data that's stored permanently on the blockchain. In other words, you save more if you're going to store the data over a long period of time.

To have a self-sufficient and sustainable ecosystem, it's also very important to build a large developer community that can create many new applications to address the different needs of businesses, government organisations and individuals, which in turn attracts more users to participate on the platform.

Unlike most competitors, Arweave is built by developers for developers. Their REST APIs allow builders to create Arweave apps in any programming language. This motivates and encourages more users. At the time of writing, Arweave development community has already started building apps even before mainnet launches.

Here are some featured apps that have already been built:

Woah! But how's that possible?

Arweave is built on four technological layers, each of which contributes to a new type of blockchain network that's suited for both fast transactions and low cost permanent storage.

• Blockweave

A new distributed ledger that's designed to provide scalable on-chain storage in a cost-efficient manner. Blockweave is the backbone behind Arweave's project.

By storing your data on-chain, you get all of the benefits (immutability, verifiability, availability, etc.), but most importantly, it gives you the ability to pay once and store forever.

• Proof of Access

Arweave's consensus mechanism is based on proof of access (PoA) and proof of work (PoW). Together, they guarantee data availability at zero cost while assuring that the energy (electricity) used while mining decrease over time.

This is made possible because at Arweave, data storage 'work' offsets hashing 'work'. The more data is stored in the system, the lower the proportion of work in the energy expending hashing side.

• Wildfire

Arweave's self-organising decentralised algorithm that allows the network topology to adapt autonomously to the most efficient routes of information distribution through the use of ranking system and incentives.

As nodes in blockweave require fast access to data in order to mine efficiently, miners are "selfishly" incentivised to store and share data quickly so as to build a positive reputation, which indirectly supports for low-latency, high bandwidth data writing and recall.

• Blockshadows

A fast and flexible block distribution system that ensures transactions are processed and distributed quickly around the network, with consensus about blocks to be achieved at near network speed.

Blockshadows are detailed instructions (e.g. tx hash, wallet list hash) necessary to rebuild a specific bock from its related transactions. Only these small-sized "shadows" are moved around the network, which minimizes congestion and allows blockweave to achieve higher speed with scalability topping at around 5,000 transactions per second.

Who is Arweave for?

A low cost, permanent storage won't be very valuable to a person who wouldn't have any trouble buying tons of physical storage and devising a solid, redundant backup plan on their own.

Based on all that, Arweave seems more geared towards those who don't feel as confident about safeguarding their digital files, and are looking for cheaper and better cloud alternatives. And in that regard, Arweave seems to be offering a lot of peace of mind.

If you have a business, evaluating and mindfully selecting the most suitable and affordable data storage service is a weighty decision. Nowadays, many services like Dropbox, Google drive or One Drive allow you to store data on the "cloud". It's free until you reach a certain limit. After that, the price can reach up to more than $100 per month. Today, Arweave is giving you the possibility to store data at a fraction of the cost and limitless.

As a data storage blockchain protocol, Arweave is well-poised for the huge data economy future. The ability to build on top of a decentralized low-cost blockchain structure that permanently stores your data is a "dream come true" for many businesses or developers.

Now, not only can you store personal and corporate files for a one-time fee instead of monthly subscription, you can also have many opportunities and possibilities. Here are two examples that I love to see happening in the near future:

• Decentralized Identity: Since data can be saved permanently and tamper-proof, we can have our personal identity created online, stored and accessed digitally. After that, probably we don't even need a physical ID card to prove who we are.

• Decentralized P2P File Sharing: Have you ever felt annoyed when you finally got hold of that torrent file, but then there's no seeders online every time? This can change with Arweave! Imagine a P2P file sharing network where there's always at least 1 seeder, no matter what. The best part - other than guaranteed anonymity, the file is stored forever (no third parties are able to take them down).
