Problems solved by technology

[0005] Existing problems: 1) There is a risk of running away in centralized transactions, and users will lose Tokens if this happens; 2) Withdrawing Tokens from the exchange requires additional fees; 3) Bidding transactions or otc transactions may also be rejected extra charge
[0008] Problems: 1) Multiple transactions; 2) Rely on smart contracts issued by third parties; 3) Smart contract execution requires additional costs; 4) There are security holes in smart contracts, and Token may also be lost
[0009] The above two exchange methods have the following problems: 1) multiple transactions, high time cost; 2) more fees than ordinary blockchain transfer transactions; 3) heavy dependence on third-party specific exchange steps, security risks High, Token may be lost

specific Embodiment

[0029] System network of the present invention such as figure 2 As shown, each network node in the figure can create the Token exchange transaction structure described in the present invention, and can also verify its transaction signature to ensure that the transaction is the consensus of both parties.

[0030] A and B have completed the exchange of willingness to exchange Tokens on the same blockchain (this communication can be face-to-face, or use various existing communication methods): A exchanges m TokenA and B for n TokenB. Then, A and B can be completed through the following methods. This method also designs a set of rigorous transaction signature step logic using third-party communication tools for information transmission:

[0031] ① A and B use a third-party communication tool to discuss the exchange rate and exchange amount of TokenA and TokenB. After confirmation, B sends its own blockchain address (which holds TokenB) to A (using a third-party communication too...

Abstract

The invention discloses a blockchain network method supporting different Token exchange transfer transaction verification. The method comprises the following steps: A creates an exchange nested transaction by using an own blockchain node operation interface, and signs the nested transaction by using an own private key, the A copies a singed character string and sends the signed character string toB through a communication tool; the B sticks the signed character string to a multi-signature transaction operation interface of an own blockchain node, if being correct, the B signs the transactionagain and sends the transaction to a Blockchain network at the same time; and the other nodes in the network receive the nested transaction sent by the B, and firstly read a transaction type, the nested transaction verifies whether the nested transaction structure is correct, whether the two signatures of the nested transaction are legal, and whether the input transaction is legal at first, if so,joins a trading pool, performs hash calculation and broadcasts the transaction to the next node. By adoption of the blockchain network method disclosed by the invention, no smart contract is needed to serve as an intermediary agent, thus being convenient and quick, improving the transaction efficiency, being safe and reliable, and being conducive to promotion.

Description

technical field [0001] The invention relates to a blockchain network method that supports verification of different Token exchange transfer transactions. Background technique [0002] Now blockchain technology is becoming more and more popular. Token is a derivative of the blockchain network. For a multi-Token blockchain network (multiple Tokens are derived from a blockchain network). The one-way transfer transaction of Token can be conveniently and safely completed on the existing blockchain network. How to exchange different Tokens conveniently and safely has always been a hot topic in the industry. Currently, there are two methods in the industry to exchange tokens on the same chain: [0003] 1. Exchange intermediary mode, two kinds of Token need to leave the blockchain network [0004] The exchange acts as a trading intermediary. A withdraws its m Token A on the Y blockchain to A’s exchange account, and B withdraws its n Token B on the Y blockchain to B’s exchange acc...
