Abstract

This disclosure provides a public chain-based token exchange method and blockchain system. According to the method, in actual applications, by means of initiating the supply 5 transaction to the public chain, a plurality of supply chains exchange the respective supply tokens provided thereby for the public chain tokens having an equal value; the public chain stores various supply tokens transferred by the supply chain and records the supply quantities; the exchange chain initiates the exchange transaction to the public chain, so that the public chain calculates the exchange rate based on the supply quantities of the initial 10 tokens and the exchange tokens that are specified in the exchange transaction, and subsequently extracts, from the stored supply tokens, the exchange tokens haivng an equal value to the initial tokens and transfers the exchange tokens to the exchange chain. By means of calculating the exchange rates between different types of tokens by using the public chain, the method may provide an objective and reasonable exchange environment. 15 Moreover, after the supply transaction takes place, the public chain stores the supply tokens so that the exchange chain performs the exchange transaction with the public chain only when performing the transaction, without contacting the exchange counterparty, thus preventing a centralized program from participating in. In this way, the exchange efficiency is improved. 20
