Arweave

Arweave is unique in its approach to data storage and preservation. It uses a "blockweave" technology, which is a variation of blockchain where each block is linked to both the previous block and a random earlier block. This incentivizes miners to store more data, as they need to be able to access random previous blocks to add new ones and receive rewards. Arweave aims to create a permanent, decentralized web called the "permaweb" where data can be stored indefinitely.

The Arweave network is secured using a modified consensus algorithm called "proof-of-access" (PoA). In PoA, each new block is linked not only to the previous block, but also to a random previous block. Miners are incentivized to store more information so they can prove they can access the old blocks required to mine a new one. Arweave's mining protocol, RandomX, has been successfully audited by several cybersecurity firms.

According to Arweave's yellow paper, the project has a maximum token supply of 66 million AR. 55 million AR were minted when the blockweave's genesis block was created in June 2018, and an additional 11 million will be gradually introduced as block rewards over time.
