On-chain refers to transactions or data that are recorded directly on a blockchain and become a permanent part of its public ledger. This means the information is transparent, verifiable, and cannot be easily altered once confirmed.

On-chain activity is permanently stored and validated on the blockchain itself.

 

When a transaction is processed on-chain, it is verified by the network and added to a block, which is then linked to previous blocks. This ensures a high level of security and transparency, as anyone can view the transaction history. On-chain transactions often require network fees and may take time to be confirmed, depending on congestion and the specific blockchain. While this method provides strong reliability and decentralization, it can be slower and more expensive compared to off-chain solutions, which handle transactions outside the main blockchain.

 

 

 

 

 

Short example:

 

Suppose you send cryptocurrency from your wallet to another user.

 

The transaction is verified by the network and added to the blockchain.

 

Once confirmed, it becomes a permanent and publicly visible record that cannot be changed.
