A method and a system for multidimensional Blockchain mining can utilize a 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 can be 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 can be obtained that is more solid with regards to its incident information contents. A technical advantage of this action includes how the search operations can be performed over the optimized chain once it is edited. The above changes can result in lower usage of server resources giving the opportunity to handle more events with the same number of resources.

Systems and methods of the present disclosure enable reversible blockchain operations. An operation-reverse operation pair specifies an operation for exchange of a first token for a second token, and a reverse operation for return of the second token for the first token upon at least one condition being satisfied. A self-executing software container (SESC) executes the operation-reverse operation pair according to the condition by detecting a transfer of the first token into a first segregated data structure, and a transfer of the second token from a second token storage to a first token storage. The SESC initiates a transfer of the first token from the first segregated data structure to a second segregated data structure in response to the transfer of the second token. Upon detecting a reverse operation matching the condition, the SESC initiates a transfer of the first token back to the first segregated data structure.

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.
