Blobber Staking.

All Service Providers must stake ZCN on their server. The Active Set (Miners and Sharders) and Blobbers have a similar staking process with slight differences:

Blobber Staking

A Blobber stores files for a client in exchange for a payment in ZCN.

Prior to starting the storage service, the client and blobber agree on the payment amount, size of the allocation and their geolocation. The terms of this agreement are written into a smart contract transaction with deposits from both the client and blobber which are locked in their respective pools. The tokens move from the client pool to the blobber when the latter passes challenges over the period of service.

Miner & Sharder Staking.

Miners and Sharders validate and maintain transactions published on the Züs blockchain. Together they represent a group of 141 network nodes — 111 Miners and 30 Sharders. This group is referred to as the Active Set.


Each member of the Active Set is required to collateralize their node with a minimum of 50,000 ZCN stake for the first year of mainnet. Each member of the Active Set generates earnings on transaction fees and block rewards.
