On-Chain
blockchain · transaction
Recorded or executed directly in transactions governed by a blockchain's base-layer rules.
1.general
On-chain activity is represented in base-layer transactions and becomes part of the accepted ledger when included in blocks. Payments, token transfers, contract state changes, and data commitments can all be on-chain.
2.properties
On-chain records inherit the chain's validation, finality, privacy, capacity, and fee properties. They are not automatically correct, private, irreversible, or free from application and contract risk.
3.data
Confirmed data can remain reproducible from block history even when ordinary nodes prune old block files. Indexers and archival services may be needed for convenient historical queries, and reorganizations can change recent accepted history.
