I got curious and looked it up. I found this[0]: > As the storage miner receives each piece of client data, they place it into a sector. Sectors are the fundamental units of storage in Filecoin, and can contain pieces from multiple deals and clients. > Next, a process called sealing takes place. During sealing, the sector data is encoded through a sequence of graph and hashing processes to create a unique replica. The encoding process is designed to be slow and computationally heavy, making it difficult to spoof.
