+
+Arweave is a distributed, permanent storage network. Built on top of the network sits the Permaweb, which is a decentralized, permissionless web. The two layers enable users and developers to:
+
+– store data permanently
+
+– deploy dynamic and permissionless dApps to the Permaweb
+
+– write smart contracts in JavaScript, Rust, Solidity and more
+
+– create profit sharing communities
+
+### How does Arweave work?
+
+The workings of the Arweave protocol can be best understood by looking at the
+two layers involved: the Arweave network
+and [the Permaweb](https://arweave.medium.com/welcome-to-the-permaweb-ce0e6c73ddfb).
+
+#### The Arweave network
+A [P2P protocol](https://www.webroot.com/in/en/resources/glossary/what-is-peer-to-peer-networking)
+that allows miners
+([nodes](https://learn.bybit.com/blockchain/what-are-nodes/)) with large storage
+spaces on their hard drives to connect with the network and store
+data for Arweave users. Arweave rewards these miners for offering their storage
+services through sustainable and perpetual endowments, coming from the user's one time payment to store data permanently. As the volume of data stored in a particular system increases, the
+amount of
+ [hashing](https://learn.bybit.com/blockchain/what-is-hashing-in-blockchain/)
+needed for the consensus decreases, resulting in more cost-effective data
+storage.
+
+The network uses a blockchain like structure called blockweave. The **_blockweave_** is different from the typical blockchain that many cryptos are
+built upon because apart from storing transactional information, the Arweave network can also store
+custom data on each block. Though similar to other blockchains whereby each block refers to its previous, Arweave attaches a randomly selected block known as the **recall block** to the transaction.
+
+This Proof of Access consensus rewards the participating nodes in the network for storing all
+of Arweave’s transactional history. Say you want to manage a node on the
+Arweave blockchain. To receive block rewards, you must prove to blockweave that
+you have complete **_access_** to the data in the previous block, along with
+some randomly selected **_recall block_**. If you don’t have access to the
+recall block, the network will know that you aren’t storing all the
+transactional data on the Arweave network, and will thus deny you any block
+reward.
+
+### The Permaweb
+Another main component in the Arweave network is the **_permaweb_**, a
+community-owned, decentralized web layer built on top of the Arweave network. Not only does the Permaweb host permissionless, decentralized and censor resistant applications permanently, 
+it gives us the ability to create queryable transactions and smart contracts to build interactive and dynamic user interfaces with tools like GraphQL.
