What is on-chain transaction?

On-chain transactions refer to transactions that are fully verified, recorded and settled on the blockchain network . The core feature is to write transaction data into a distributed ledger and ensure immutability and transparency through node consensus mechanisms (such as proof of work PoW or proof of stake PoS).

Core features

1. Security : All transaction data is encrypted and stored in the blockchain and requires verification of the entire network node to eliminate the risk of single point tampering.
2. Decentralization : No need to rely on third-party institutions such as banks, transactions are maintained jointly by miners or validator networks.
3. Transparency : Transaction records can be traced to a unique address through a blockchain browser and can be publicly verified.
4. High cost and low efficiency : On-chain transactions require a miner's fee and may be extended when the network is congested (for example, the Bitcoin network requires 6 confirmations, which takes several minutes to several hours).
