On-chain refers to the activity or transactions that occur directly on a blockchain network. This means that any transaction, smart contract execution, or data storage that takes place within the blockchain itself is considered to be on-chain activity.
When a transaction is conducted on-chain, it is recorded on the decentralized ledger and becomes a permanent part of the blockchain. This ensures immutability and transparency, as the transaction history is publicly verifiable by anyone on the network.
On-chain transactions typically require network consensus through mechanisms like proof of work or proof of stake, to validate and add them to the blockchain. This process helps to secure the network and maintain the integrity of the blockchain.
Overall, on-chain transactions are fundamental to the functioning of blockchain networks, allowing for trustless and decentralized interactions between network participants. By conducting transactions on-chain, users can engage in peer-to-peer transactions without the need for intermediaries.
