The invention provides improved verification solutions for blockchain-implemented transfers. It is suited for, but not limited to, implementation in an SPV wallet. In accordance with one embodiment, a system or resource is provided which comprises a plurality of novel SPV verification components, the activities of which are coordinated by a coordination component. The system enables Bob to send Alice a payment transaction template (template Tx3) and requests: the full transaction data for all input transactions (Tx1, Tx2) comprising at least one output that Alice wants to spend as inputs to a transfer (Tx3); the Merkle path for all input transactions (Tx1, Tx2) linking them to their respective Merkle roots associated with their respective block headers; the completed transfer transaction (Tx3). Alice provides this information plus her signature. Bob can then perform local SPV checks on the input transactions Tx1, Tx2 using transactions Tx1 and Tx2, their corresponding Merkle paths Path 1, Path 2, and Error! Bookmark not defined. Bob's local list of block headers. Bob broadcasts the transfer transaction (Tx3) to the P2P network.

To request that an unlocked script of a transaction in a blockchain includes a block header, a blockchain, or a chain of block headers.SOLUTION: A method includes receiving, at a node in a blockchain network, a first transaction associated with a digital asset. The first transaction includes a first script that specifies a set of constraints on a second transaction to transfer control of the digital asset, and the set of constraints includes a constraint that a set of data obtained by the node includes information obtained from a blockchain associated with the blockchain network. The method obtains the second transaction. The second transaction includes a second script that, as a result of being executed, causes the node to obtain the set of data. The method further validates the second transaction by executing the first and second scripts.SELECTED DRAWING: Figure 1

Systems and methods described herein relate to techniques in which multiple parties each generate and exchange quantities that are based on a shared secret (e.g., powers of the shared secret) without exposing the shared secret. According to a protocol, two or more parties may exchange sets of elliptic curve points generated over polynomials that can be used, by each of the two or more parties, to determine a power of a shared secret. The protocol may be utilised as part of determining parameters for a smart contract that is broadcast to a blockchain network (e.g., Bitcoin). Based on the protocol, an additional party (e.g., a third party different from the two or more parties) may perform a computational task such as execution of the smart contract.

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.
