Arweave is a data storage protocol built on blockweave technology. Arweave is developing an underlying network where data can be stored forever and accessed on its permaweb, a secondary layer where data is accessible in a human-readable manner (e.g. via web browsers). The Arweave team has implemented a few core technologies for the Arweave protocol including blockweave, Proof of Access, wildfire, and blockshadows. Blockweave and Proof of Access Arweave's protocol combines a new data structure called a "blockweave" and a new consensus mechanism termed Proof of Access (PoA). As the name suggests, the blockweave protocol utilizes a block-based structure where each block is linked to two blocks: The most previous block in the Arweave blockweave The recall block, a randomly selected block within the protocol's history. The recall block is determined by taking the hash of the current block and calculating its modulus with respect to the current block height. Miners must provide hashes from both of the prior blocks in order to create a new block and earn the block reward in the form of Arweave's native token (AR). Node Architecture The protocol introduces variances to Bitcoin's node structure in which each node stores a block hash list – a list of the hashes of all previous blocks – designed to allow old blocks to be verified. Additionally, nodes possess a wallet list which contains a list of all "active wallets" in the protocol. Wildfire Arweave also utilizes a data-sharing system called "wildfire" whereby Arweave nodes are ranked based on the speed at which each node responds to requests and accepts data from other nodes in the network. Nodes that fail to quickly share information can be blacklisted from the Arweave network permanently. The design is aimed at incentivizing good behavior amongst nodes in the network. Blockshadows Further, Arweave implements another data management system called "blockshadows" – a process in which transactions are partially decoupled from blocks in favor of only sending other nodes a minimal block (the shadow) that enables other nodes in the network to re-create the full block. Blockshadows contain a hash of the wallet list, hash list, and a list of transaction hashes from the current block. Permaweb Another notable aspect of Arweave's network is the "permaweb" which sits atop of Arweave's data storage layer. The permaweb is the human-readable layer that contains the collection of documents and applications of which the data is stored permanently on the Arweave protocol. Because the Arweave network is built on top of the HTTP protocol, browsers have the ability to access permaweb documents and applications.
