Many project collaborations often fail not due to technical capabilities, but during the delivery phase. Imagine this: you need to hand over sensitive materials like whitelists, research data, and training sets to your partner, only to have the other side turn around and say "the version received is different," leading to endless explanations. Even more frustrating is that some data cannot be disclosed in advance, but you must have the other party confirm receipt beforehand, or the entire project schedule could come to a halt.

This kind of dilemma actually stems from the lack of a solid, trustworthy delivery benchmark. The Walrus protocol offers a solution: first encrypt the files locally, then store the encrypted data as referenceable objects on the network. Both parties agree that "the same item has been delivered and points to the same on-chain address," and at the agreed time, they can decrypt the data. The advantage of this approach is that—delivery, confirmation, and traceability are no longer dependent on chat logs and screenshots, but rely on timestamps and version records on the blockchain.

When disputes arise, they become clearer: both parties no longer need to argue over "whether you changed this file or not." By aligning versions and timelines first, responsibility boundaries are clearly defined. From this perspective, storage costs are not just about expenses; they empower "trustworthy delivery"—allowing collaboration to start first and unlock according to rules, rather than relying on personal trust and goodwill every time. The more important the data and the more participants involved, the more significant the value of "locking in facts first, then expanding collaboration" becomes.
