What Does Onchain Mean?
Onchain refers to any activity, transaction, or data that is recorded directly on a blockchain. When something happens onchain, it is validated by the network’s participants, added to a block, and permanently stored on the distributed ledger. This makes onchain activity transparent, verifiable, and resistant to tampering.
Onchain transactions typically involve transferring assets, interacting with smart contracts, or updating blockchain data. Because each transaction must be confirmed by miners or validators, onchain actions can take time and may require paying a network fee. The speed and cost depend on the blockchain being used and current network conditions.
In contrast to offchain activity, onchain records can be independently verified by anyone using a block explorer. This visibility is a key feature of decentralized systems, as it allows users to confirm transactions without trusting intermediaries.
