Cloud storage is controlled by a few tech giants, but there are always people trying to break this monopoly. Walrus, a blockchain protocol, has recently attracted attention with its ambitious goal—to reshape the entire storage ecosystem.

Why does it have confidence? Simply put, it has solid technology. Walrus's core idea is very interesting and completely different from traditional cloud services. Instead of storing your files intact in a data center, it adopts a distributed approach.

How does it work? The first step is to treat large files as binary large objects (Blob). The second step is the key—erasure coding. The system splits the Blob into N data fragments and then generates M parity fragments (which can be understood as recovery passwords). The brilliance lies here: even if up to M of the original N fragments are lost, any remaining N fragments can perfectly restore the entire file.

How powerful is this combination? Data is extremely dispersed across global nodes, making it impossible for anyone to access the complete file, truly safeguarding privacy. Even more impressive is its fault tolerance—node outages or data corruption are no concern; the file remains secure at all times. In other words, it achieves true resistance to censorship and perpetual storage. This has profound implications for building privacy infrastructure in the DeFi ecosystem.
