Many people have a deeply ingrained misconception about Web3 — they think that once data is on the chain, everything is "immutable" and beyond tampering. In reality, this logic is full of flaws.

It's true that you can't change the records of your transfer transactions, but the images of NFTs you buy, the attribute data of equipment in blockchain games, the price data called by DeFi applications — these "actual contents" are constantly being secretly replaced, and the blockchain itself remains unaware of it.

Imagine a company's ledger. It clearly states "Xiao Li purchased a Ferrari" (this transaction can never be changed), but the actual car is parked in someone else's warehouse. If the warehouse manager swaps the Ferrari for a bicycle, the ledger remains unchanged, and Xiao Li has no way to prove the car was swapped.

This is the fundamental reason why today's Web3 applications are generally superficial. Why are blockchain games so simple? Why are there no truly complex, long-lasting applications? Ultimately, it's because "history" itself is untrustworthy. Developers are reluctant to entrust complex logic to a system that could "forget" or "turn hostile" at any moment.

A new project has identified this problem and aims to equip Web3 with a "black box" for flight data.

The idea is straightforward: I not only help you store data, but I can also prove to the world that this data has not been altered even for a second since it was stored.

Technologically, it uses a correction mechanism called RedStuff — splitting data into fragments and dispersing them across various nodes. Even if two-thirds of the global nodes go offline simultaneously, the system can fully restore the data; even if a node tries to modify a bit, the entire network can immediately detect the anomaly.

The value of this capability is actually quite significant:

Blockchain game developers will finally dare to create complex games. The biggest fear before was data loss, but now with complete proof of data integrity, game progress and transaction records from years ago can be verified, preventing users from denying their actions. The NFT ecosystem can truly protect buyers' rights. You can fully prove what the original asset looked like at the time of purchase, preventing project teams from swapping "gold" for "junk" midway. AI applications will have a reliable training foundation. Large models require vast amounts of historical data; if the data source itself is untrustworthy, AI can't be smart enough regardless.

Most interesting is its dual-token design, which breaks the common pattern.

It doesn't force you to use the native token of a particular main chain to store data but instead issues a dedicated storage token. The specific division of roles is as follows:

The main chain token is used for accounting and paying transaction fees, while the storage token is responsible for purchasing storage space and providing a guarantee mechanism.

This way, storage costs become stable and won't prevent ordinary users from storing files due to sharp fluctuations in the main chain's token price. It solves both the issues of data integrity and cost transparency simultaneously.
