[0004] The centralized trading system requires user registration. The transfer of token exchange is divided into two steps, non-atomic operation, and the exchange rate between tokens is formulated by the central organization. These mechanisms increase the risk of token exchange. The center There is a single point of failure in the organization. Once hacked, the consequences will be disastrous

Embodiment 1
[0031] Such as figure 1 As shown, a blockchain token trading system with adaptive exchange rate changes, including:
[0032] Data storage layer, which saves the historical data of token transactions and transmits the data to the smart contract layer;
[0033] The smart contract layer is configured to include the exchange contract module and the Oracle contract module;
[0034] The Oracle contract module is connected to external data source services, reads and processes external data, and transmits it to the exchange contract module;
[0035] The exchange contract module has a built-in token exchange engine and AI analysis engine, which calculates the exchange rate of the token and performs the exchange according to the exchange rate.
[0036] In practical applications, the Oracle contract is the currently widely used blockchain oracle mechanism. If a contract on the blockchain needs to read external data, it only needs to call the data acquisition interface of the Oracle con...
Embodiment 2
[0049] A block chain certificate transaction method for adaptive change of exchange rate, the block chain pass transaction method for adaptive change of exchange rate comprises the following steps:
[0050] Step S1: The user issues a token and registers in the token trading system;
[0051] In practical applications, the user issues the token and registers in the token trading system as follows: the user registers his own contract with the exchange contract module when the token is issued, and grants the exchange contract module the authority to issue and withhold the token .
[0052] In practical applications, the user registers his own contract in the exchange contract module to back up the contract issued by the user in the system, and then the value of the contract issued by the user can be evaluated.
[0053] In practical applications, the exchange of contracts is carried out through the intermediary of the token exchange engine built in the exchange contract module.

Abstract
The invention discloses a blockchain token transaction system with a self-adaptive change exchange rate. The system comprises a data storage layer; an intelligent contract layer; an Oracle contract module connected with an external data source service, used for reading and processing external data and transmitting the external data to the contract exchange module; an exchange contract module whichis internally provided with a token exchange engine and an AI analysis engine, calculates a token exchange rate and performs passport exchange according to the exchange rate. The invention also discloses a corresponding method. The method comprises the following steps: a user issues the token and registers in the token transaction system; the token transaction system acquires external data and token transaction historical data in real time and performs processing and calculation to obtain token exchange exchange rate; the user inquires the exchange exchange rate and initiates token exchange;and the token transaction system completes token exchange according to the exchange exchange rate. The token exchange contract and the token value evaluation system are built in the token exchange system, exchange between different tokens held by the user can be realized without intervention of a centralized mechanism, and the token exchange system is efficient and transparent.
Description
technical field [0001] The invention relates to the field of token transactions, in particular to a blockchain token transaction system and method for adaptively changing exchange rates. Background technique [0002] The current blockchain-based tokens effectively solve the problem of cross-institutional circulation, such as tokens based on alliance chains, which can be circulated among alliance members. An alliance can be an industry alliance or a cross-industry alliance , Tokens can represent certain rights and interests, such as the ownership of warehouse goods. The circulation of Tokens represents the circulation of goods rights, and can also represent some kind of rewards, such as points, which can be exchanged for certain services of the system. [0003] Different tokens can be exchanged for each other. Multiple tokens on one consortium chain and tokens on different consortium chains can be exchanged at a certain exchange rate based on their value. The traditional solu...
