On-Chain / Off-Chain

On-chain means recorded on a blockchain - a transaction, a token balance, a contract's state. Off-chain means everything else: a bank account, a building's title, a legal agreement, a company's books. The distinction is central to real-world assets, because the asset is off-chain and the token is on-chain.

That gap is the whole challenge of the field. A blockchain can prove, perfectly, that you hold a token. It cannot see, on its own, whether the building that token represents still exists, who holds the deed, or whether the rent was paid. Those are off-chain facts.

Three things bridge the gap:

• Legal structure connects the token to the underlying asset, so owning the token means owning a real claim.
• Oracles feed off-chain data - prices, interest rates, NAV - to smart contracts that need it.
• Attestations let trusted parties sign off-chain facts (reserves exist, a wallet passed KYC) into a form code can check.

Knowing which parts of a deal are on-chain and which are off-chain tells you where the trust actually sits. The token transfer may be trustless, but the claim behind it depends on off-chain law and off-chain custody. A project that blurs this - implying the blockchain guarantees the asset - is hiding its real risks.

The honest way to read any RWA: on-chain for settlement and record-keeping, off-chain for the asset, the law, and the people. Both have to work.
