  • Patent number: 11537473
    Abstract: The invention discloses a method for controlling other systems based on a single-point execution contract, comprising the following steps: A, when a contract developer writes a single-point execution contract code, integrating a command needing transparent transmission into the code; B, executing, by a virtual machine, the code, calling a transparent-transmission channel command input interface while executing to a row with the command, and transmitting the command to a blockchain node; and C, not processing the command by the blockchain node, and calling a secondary development service package interface through the transparent-transmission command to transmit downwards. In the method, a command transparent-transmission channel and a transparent-transmission command secondary development package service are designed, so that a blockchain user can operate their specific software/hardware equipment through a user-defined command.

  • Publication number: 20220253457
    Abstract: The present application provides a block generation control method applied to a blockchain and a related apparatus, which relate to the technical field of blockchains. The block generation control method includes: triggering a current speaker node and a current deputy speaker node in the two or more congress member nodes to generate two candidate blocks, respectively; triggering all or part of nodes in the two or more congress member nodes to vote on the two candidate blocks generated, to generate a voting result; and determining, based on the voting result, one candidate block of the two candidate blocks that satisfies a preset vote number condition as a new block of the blockchain.

  • Patent number: 11012229
    Abstract: The present invention discloses a method for preventing short-term bifurcation and double-spend attack on a block chain network. The method includes the following steps: adding one CA certificate issuance and updating center to the blockchain network; transforming a block data structure and adding a CA certificate-based signature and a public key field; adding certificate effective verification of the signature and the public key to a consensus algorithm of a blockchain network node; improving the consensus algorithm; adding risk identification of a short-term bifurcation malicious double-spending attack to the improved consensus algorithm. The present invention makes minor changes to an original chain and is easy to implement. Because the method only adds the CA center and modifies and adds the necessary consensus algorithms, the method may effectively reduce the possibility of short-term bifurcation double-spending attack.
