Disclosed are a quantum key-based blockchain network and a data secure transmission method. According to the specific architecture of the blockchain network, a corresponding quantum key distribution network is deployed to provide required quantum keys for blockchain nodes, so as to allow quantum key-based data secure transmission. Therefore, a symmetric key can be provided for blockchain nodes by means of high-security quantum key distribution technology, thereby ensuring that the key cannot be effectively intercepted in a distribution process, and in addition, an unpredictable true random number is generated by means of a quantum random number source, thereby ensuring that it is difficult to predict the random number and thus greatly improving the security of the symmetric key and improving the security of data transmission between blockchain nodes. The present invention is particularly suitable for blockchain systems requiring high security protection, such as on-chain government affairs, on-chain free trade and the like.
Resumen de: EP4432192A1
A simulation method implemented at least in part at a node of a blockchain network enables detection of suspected malicious behaviour. When a purchase of a token of interest by a user is detected, information about other queued transactions awaiting committal to the blockchain is retrieved, and a batch of probing transactions is constructed using the information about the queued transactions. The batch includes a probing transaction representing a sale of the token by the user. At the node, the state of the blockchain is overridden so that the user's wallet and other wallets appear to contain bytecode executable to aggregate multiple transactions into a single call, and the batch of transactions is thus executed in a single call. The results are evaluated to determine whether the sale of the token by the user was successful. If the evaluation is not successful, remedial action may be taken.

Resumen de: US2024303659A1
A deterministic concurrency control protocol for a blockchain is described. A set of transactions of the blockchain are received at a node. A simulation step and a commit step are performed to process the transactions. A dependency graph is generated comprising the set of transactions and a set of dependencies between the set of transactions, the set of dependencies including one or more read-write dependencies. A backward dangerous structure is identified in the dependency graph. The backward dangerous structure includes a first read-write dependency from a second transaction to a first transaction, and a second read-write dependency from a third transaction to the second transaction. A transaction is aborted based on the identified backward dangerous structure. Each non-aborted transaction is committed. Steps for update reordering, update coalescence, and inter-block parallelism are described.
