Embodiment

[0042] like figure 1 Shown, a kind of method based on block chain random number generation algorithm is characterized in that, comprises the following steps:

[0043] Step 1: The participant selects the server, the server generates a random number, and records the hash value of the random number to the blockchain;

[0044] Step 2: The server sends the information on the blockchain to other participants and collects random numbers from other participants;

[0045] Step 3: The server sends the random number of the participant, the random number generated by the server and the information of the delayed waiting block number to the blockchain;

[0046] Step 4: The server sends the information on the blockchain in step 3 to other participants, and all participants wait for the set block to calculate the final random number.

[0047] like figure 2 as shown,

[0048] All participants choose a server, and the server generates a random number N server And calculate the hash value...

Abstract

The invention relates to a random number generation algorithm method based on a block chain, which comprises the following steps: step 1, a participant selecting a server side, the server side generating a random number, and recording a hash value of the random number on a block chain; step 2, the server side sending information on the block chain to other participants, and collecting random numbers of the other participants; step 3, the server sending the random number of the participant, the random number generated by the server and the information of the number of delayed waiting blocks toa block chain; and step 4, the server sending the information on the block chain in the step 3 to other participants, and after all the participants wait for the set blocks, calculating a final randomnumber. The whole process is recorded on the chain and is public on the chain, tampering is prevented, and safety is improved.

Description

technical field [0001] The invention relates to a block chain-based random number generation algorithm method. Background technique [0002] Blockchain technology, referred to as BT (Blockchain technology), also known as distributed ledger technology, is an Internet database technology, which is characterized by decentralization, openness and transparency, allowing everyone to participate in database records. [0003] Transaction: An operation that causes a change in the state of the ledger, such as adding a record; [0004] Block: Records transactions and state results that occurred within a period of time, and is a consensus on the current ledger state; [0005] Chain: It is composed of blocks connected in series in the order of occurrence, and is a log record of the entire state change. [0006] If the blockchain is used as a state machine, each transaction is an attempt to change the state, and the block generated by each consensus is the result of the participant's co...
