A blockchain oracle is a service that brings outside data, such as asset prices or event results, onto a blockchain so smart contracts can use it. Contracts cannot fetch that data themselves.
A real world asset (RWA) is a physical or traditional financial asset whose ownership or economic rights are represented by a blockchain token. Examples include property, bonds, invoices and commodities.
A smart contract is a program deployed on a blockchain that runs exactly as written whenever it is called. It can hold and move digital assets according to its own rules, without an intermediary.
A stablecoin is a cryptocurrency designed to hold a steady value, usually against a national currency such as the US dollar. It stays stable through cash reserves, crypto collateral or supply rules.
Blockchain interoperability is the ability of separate blockchains to exchange data, assets and messages so applications can work across them. It relies on bridges, messaging protocols and shared standards.
