Shards and Epochs Are How the Network Stays Organized
Walrus publishes fixed parameters that explain how it scales. It lists 1000 shards on both mainnet and testnet. A shard is a partition of responsibility, so the whole network does not act like one giant bucket.
Walrus also uses epochs, which are time periods used for scheduling and accountability. Docs list epoch duration as 2 weeks on mainnet and 1 day on testnet.
One more constraint is easy to miss but important for planning: the maximum number of epochs you can buy storage for at once is listed as 53 (you can renew later).
These details are not marketing. They are the “physics” of the system.
