BZZ is the native token of Swarm, a decentralized storage and data-sharing network that grew out of the Ethereum ecosystem. In plain terms, it's the money used to pay for storing and retrieving files on a network of independent nodes instead of corporate servers, and it's also how those nodes get rewarded. The ticker BZZ is what you'll see on exchanges and price trackers.
Frequently asked questions
What is BZZ, and how is it different from Bitcoin or Ethereum?
BZZ isn't a general-purpose currency — it's a utility token for Swarm, a decentralized storage network. While Bitcoin is mainly digital money and Ethereum is a smart-contract platform, BZZ exists specifically to pay for storage and bandwidth and to reward the node operators who keep the network running.
How does Swarm's technology actually work?
Files uploaded to Swarm are split into small chunks, encrypted, and spread across many independent nodes, with each piece addressed by its content hash — so data stays available even if some nodes go offline. BZZ itself lives as an ERC-20 token on the Ethereum blockchain, which handles ownership and transfers, while Swarm handles the storage layer. Nodes earn BZZ for storing and serving data, which is what keeps the whole system running.
How is BZZ issued, and is the supply limited?
Yes — BZZ has a hard cap of 63 million tokens. It was originally issued through a bonding curve on Ethereum: you deposit ETH and the contract mints BZZ, and when tokens are returned they get burned, which keeps the supply elastic but never above the cap.
How can I store and use BZZ?
Since BZZ is an ERC-20 token on Ethereum, any Ethereum-compatible wallet works — MetaMask, hardware wallets like Ledger, or an account on a trusted exchange. Beyond holding and trading, you can spend BZZ to store data on Swarm or earn it by running your own storage node.
