The native token AR of the Arweave network is unique in blockchain technology. This network employs an innovative Proof of Access (PoA) consensus mechanism, cleverly integrating the advantages of Proof of Work (PoW) and Proof of Random Access (PoRA).

The core of the PoA mechanism lies in requiring nodes to not only verify the workload but also to access and store historical data. This design ensures the persistence and accessibility of data, somewhat similar to Bitcoin's PoW, but with a greater emphasis on the long-term preservation and verification of data.

In February 2021, the Arweave network completed a significant upgrade, introducing the Sparse Proof of Random Access (SPoRA) mechanism. This upgrade brought several notable improvements: first, it restricted miners' freedom to retrieve data from the network; second, it significantly reduced the network's energy consumption; and most importantly, it increased the number of data copies stored in the network to 100-1000 times the original, while shifting more computational tasks to the storage aspect.

Another innovation of Arweave is its Profit Sharing Token (PST) mechanism. Applications developed based on the Arweave protocol can issue PST. When users interact with these applications and generate transactions on the network, the system automatically sends rewards denominated in AR to PST holders, with the reward amount distributed according to the holding ratio.

These technological innovations not only improve the efficiency and scalability of the Arweave network but also provide new incentive models for developers of decentralized applications, promoting the healthy development of the entire ecosystem. With continuous technological advancements, Arweave is expected to play a greater role in the fields of data storage and blockchain applications.
