Problems solved by technology

Even on the Ethereum blockchain (Ethereum) platform that uses Turing's complete language Solidity, for example, malicious users can still pay a higher "fuel / Gas" to carry out double payment attacks, so that transactions made later will be blocked first. However, for earlier transactions, the verification will fail because the node finds that there is not enough cryptocurrency balance for payment when confirming the corresponding wallet address, so that the counterparty of the earlier transaction cannot obtain the transaction.

[0028] The first embodiment of the present invention is an authentication server for blockchain transactions. Please refer to figure 1 and figure 2 , figure 1 It is a schematic diagram of the authentication server used in blockchain transactions in this embodiment. figure 2 It is a schematic diagram of the architecture of the authentication server in this embodiment. The authentication server 1 is coupled to the blockchain network 4 and includes a storage unit 11 , one or more processing units 12 and one or more output / input units 13 . In this embodiment, one processing unit 12 and one output / input unit 13 are used as an example for illustration. The storage unit 11 stores a plurality of instructions (such as program codes). The processing unit 12 is coupled to the I / O unit 13 and the storage unit 11 . The storage unit 11 includes a random access memory or a non-volatile computer-readable storage medium, etc. The non-volatile computer-readable storage medium is, for ex...

[0041] In addition, the present invention also proposes an authentication method for blockchain transactions, which is performed by using the authentication server 1 coupled to the blockchain network 4 provided in the foregoing embodiments. Please refer to image 3 , is a schematic flowchart of the authentication method in this embodiment. The authentication method in this embodiment includes the following steps. Step S1: The authentication server 1 receives the transaction application data sent by the user. The transaction application data includes wallet data, and the wallet data includes wallet address data and user signature data. Step S2: The authentication server 1 checks on the blockchain network 4 whether the balance of the encrypted currency corresponding to the wallet address data is sufficient for the transaction; and, Step S3: When the balance of the encrypted currency is sufficient for the transaction, the authentication server 1 will send more Sign the wallet t...

Abstract

The invention provides an authenticating server and a method for transactions on blockchain. The invention discloses an authenticating server and a method for transactions on blockchain. A processingunit of the authenticating server coupled to a blockchain network executes a command stored in a memory unit to carry out: (1) receiving a transaction application data from a user, wherein the transaction application data includes a wallet data containing wallet address data and user's signature data; (2) checking whether an amount of a crypto-currency corresponding to the wallet address data on the blockchain network is sufficient to perform the transaction; and (3) when the amount of the crypto-currency corresponding to the wallet address data on the blockchain network is sufficient to perform the transaction, transmitting a multi-signature wallet transaction data to the blockchain network for validating a blockchain operation, and send a confirmation data of the transaction associated with the transaction application data to an opposing party of the transaction. The multi-signature wallet transaction data includes the wallet address data, the user's signature data and signature dataof the authenticating server.

Description

technical field [0001] The invention relates to a transaction authentication method and server, in particular to an authentication method and server for blockchain transactions. Background technique [0002] Blockchain is a distributed digital ledger that adopts a consensus algorithm, and the most widely known application of blockchain technology is cryptocurrency. Cryptocurrency based on blockchain technology has the characteristics of decentralization and is not subject to the supervision of central banks of various governments. At the same time, the records of cryptocurrency transactions are in principle permanent and cannot be retroactively modified, and can be verified and traced. For example, in the traditional decentralized transaction process, one party to the transaction initiates, signs with its user's private key, and submits the transaction content and its digital signature to the blockchain for verification and recording by each node. In order to ensure securi...
