Examples of a method and apparatus for cross-chain resource transmission are described. The cross-chain resource transmission includes sending from a first account of a first blockchain to another blockchain. One example of the method is executed by the first blockchain and includes: initiating, by the first account, a first transaction used for cross-chain resource transmission, to decrement a first resource balance of the first account by a first quantity and save first data obtained through a consensus into the first blockchain based on execution of the first transaction, where the first data includes an authenticable message; and sending the first data and first location information to the relay end, which is used to send the authenticable message to the second blockchain, where a second resource balance of the second account is incremented by a second quantity.
