Arweave's protocol combines a new data structure called a "blockweave" with a Proof of Access consensus mechanism (PoA).
Arweave also employs a "wildfire" data-sharing system, in which Arweave nodes are ranked based on how quickly they reply to requests and take data from other nodes in the network.
Another data management technique used by Arweave is "blockshadows," which comprise a hash of the wallet list, a hash list, and a list of transaction hashes from the current block.
Arweave network is based on the HTTP protocol; therefore, browsers can access permaweb pages and apps.
Use of Native tokens in the ecosystem:
AR is Arweave's native utility token, and it can be used for the following things:
Miner rewards: Miners in the network obtain AR tokens, which need them to store and serve data for mining new blocks. It is conceivable for a wallet owner to be both a user and a miner at the same time.
Transaction fees: Users must pay transaction fees in AR tokens to include a transaction in a block.
