Arweave and Filecoin have provided permanent data storage in a decentralized way. Those are places where users can store their data without worries about some evil central manipulations. However, the current user experience is still very bad. First of all, no matter how large data the users want to upload to the system, the transactions may need tens of minutes to complete and get finality. This largely limits the scope of application types that are suitable to be built on such systems. Some applications have to resort to Layer2 solution to work around this issue, e.g., everPay on Arweave. Secondly, it is hard for such systems to smoothly integrate into the token ecosystems of existing Layer1 blockchains. For example, both Filecoin and Arweave have their own wallet and account address schemes. This introduces barriers for users who are only familiar with Metamask wallet and Ethereum account address. And furthermore, since the ledger system in Arweave does not support (EVM compatible) smart contract, it forces the developers to rebuild the wheel of token systems on top of the Arweave’s storage infrastructure through some mechanism called Smartweave. Such efforts include RedStone, Verto, and everPay. However, comparing the already flourishing token ecosystems in existing blockchains like Ethereum, BSC, Solana, etc., it is questionable for the meaning of rebuilding such things on a storage infrastructure which is designed to handle large amount of non-financial data.
