EP_4576647_PA

Resumen de: EP4576647A1

The invention relates to a method and a system for multidimensional Blockchain mining. The method makes use of a purposely delay of the time frame of the block mining in order to use the information in the block at hand as a relay to route in specific targeted node elements. The delay, which is performed on the block mining, targets the reshaping (editing) process in the blockchain implemented in this solution. By delaying the mining, the number of blocks that is otherwise needed to be edited is limited. Additionally, a chain is obtained that is more solid with regards to its incident information contents. The technical advantage of this action is depicted in the search operations performed over the optimized chain once it is edited. The above changes result in lower usage of server resources giving the opportunity to handle more events with the same number of resources.

The invention relates to distributed ledge technologies such as consensus-based blockchains. methods for causing an injection of a serialized previous transaction into a locking script are described. The invention is implemented using a blockchain network, which may be, for example, a Bitcoin blockchain. A first transaction to validate is received at a node in a blockchain network, with the first transaction including a first script. The first script, as a result of being executed, causes the node to at least obtain a first set of field values corresponding to the first transaction and obtain a second set of field values corresponding to a particular transaction. A second transaction is obtained, with the second transaction having been validated and including a second script. The second script, as a result of being executed, causes the node to at least obtain the first set of field values and the second set of field values of the particular transaction supplied as a result of execution of the first script, extract a transaction identifier from the first set of field values, and determine, based at least in part on the second set of field values, that the particular transaction corresponds to the transaction identifier. The first transaction is validated by executing the first script and the second script.
