On-Chain
۱۴۰۵/۱/۲۷
On-chain refers to any transaction, smart contract execution, or data that is recorded directly on the blockchain and validated by the network's consensus mechanism. On-chain data is immutable, transparent, and publicly verifiable.
What happens on-chain
- Transfers — sending cryptocurrency from one address to another
- Smart contract calls — interacting with DApps, DeFi protocols, NFT mints
- Mining rewards — block rewards and transaction fees paid to miners
- Pool payouts — when a mining pool sends earned coins to a miner's wallet
On-chain vs. off-chain
| Property | On-chain | Off-chain |
|---|---|---|
| Speed | Depends on block time | Instant |
| Fee | Variable (gas/fee market) | Near zero |
| Finality | Permanent, immutable | Requires final settlement |
| Transparency | Fully public | Private or semi-private |
Relevance to miners
Every block reward and pool payout is an on-chain transaction. High on-chain fees can make frequent small payouts uneconomical — this is why many pools have minimum payout thresholds.
