Computer implemented systems and methods

Resumen de: GB2636393A

Using, processing and/or generating at least one blockchain transaction suitable for updating a blockchain token (e.g. transferring a blockchain token between entities). A transaction includes a latch mechanism for controlling the update. The latch mechanism can be described as imposing a conditional update of the token e.g. an interlock. The relationship with the previous and subsequent transactions is used to inhibit double spending or determine token validity using an inductive proof. The latch mechanism comprises: the unlatch-script, which is configured to release a preceding restriction, said preceding restriction applied in a preceding blockchain transaction and configured to restrict update of the blockchain token and/or the latch-script, which is configured to apply a subsequent restriction, said subsequent restriction configured to restrict the ability to assign the blockchain token in a subsequent blockchain transaction e.g. by the another entity.

CONSTRAINING INJECTION OF UNLOCKING TRANSACTION BYTECODE

Resumen de: EP4572228A2

The invention relates to distributed ledge technologies such as consensus-based blockchains. The methods and systems of the present disclosure are provided for causing an injection of a serialized set of field values of an unlocking transaction into a locking script are described. The invention is implemented using a blockchain network, which may for example be a Bitcoin blockchain. A first transaction to validate is received at a node in the blockchain network. The first transaction includes a first script that includes a set of field values of the first transaction and, as a result of being executed, causes the node to obtain a set of field values. A second transaction is obtained, with the second transaction having been validated. The second transaction includes a second script that, as a result of being executed, causes the node to generate a signature based at least in part on the set of field values supplied as a result of execution of the first script. The first transaction is validated by execution of the first script and the second script.

BLOCKCHAIN-IMPLEMENTED DATABASE OVERLAY, VERIFICATION AND INDEXING SYSTEM

Resumen de: CN119731657A

The embodiment of the invention provides a database covering and indexing mechanism implemented by a block chain. In one embodiment, records in a database are associated with respective unconsumed outputs in one or more transactions on a blockchain by overlay. Each output includes a lock script that specifies which keys can be used to consume the output to other transactions. When a user wishes to access a given record in the database, the other (expending) transactions are generated and sent to a blockchain network. The other transactions include an unlock script that provides one or more keys required to meet the conditions of the lock script, otherwise a consensus mechanism of the blockchain will not allow expenditure of the output and access to the record will be denied. However, if a requirement is met, the output is consumed, and an access request is considered to be authorized. In this way, the consensus mechanism provides an improved authority control and user authorization scheme for a database. When the output is consumed by the other transactions, the overlay is updated to associate the record with the consumed transaction. Transaction logs can also be provided to quickly and efficiently regenerate the database when needed.

BLOCKCHAIN TRANSACTION CLEAN-UP SERVICE

Resumen de: WO2025119607A1

Methods, devices, and data structures for processing large volumes of transactions in blockchain nodes. Solutions are provided for transaction clean-up following receipt of a block announcement from another node. In one example, transaction identifiers in a list matching the local candidate block are marked if they match transaction identifiers in the announced block and, once the block is validated, the block assembly service uses unmarked transaction identifiers to build the new candidate block. In other examples, a candidate database of transaction identifiers is built during the mining phase and TxIDs are marked with an array identifier or a node identifier as arrays are announced by other nodes on the network. This may speed clean-up once the block is announced and reduces memory footprint for carrying out the post-solution marking of TxIDs as being included in the solved block.

Resumen de: AU2025203696A1

Blockchain latency is improved by unclogging a mempool, which frees up electronic memory and reduces CPU usage and network bandwidth. Mining data of one or more initial blocks of a blockchain is accessed. The mining data reveals, for each miner, the time delay between individual transactions mined by that miner. A subset of miners is then determined to have lower time delays than miners not in the subset. Thereafter, a different random number is generated for each new block of the blockchain system to be mined. Based on a comparison of this random number and a predefined threshold, either an exploitation phase or an exploration phase is entered for the mining of each new block. In the exploitation phase, mining tasks are assigned only to the subset of the miners. In the exploration phase, mining tasks are assigned to both miners within the subset and miners not in the subset.
