Methods, devices, and data structures for processing large volumes of transactions in blockchain nodes. To prevent avoidance of validation operations by one or more nodes, a sending node creates an intentionally invalid array of blockchain transactions that contains an invalid transaction. The sending node provides the valid transaction to enable receiving nodes to replace the invalid transaction with the valid transaction, once the receiving nodes have detected invalidity of the invalid transaction, thereby enabling them to convert the invalid array of transactions into a valid array of transactions during a mining phase and prior to discovery of a block solution. The providing may be by way of direct peer-to-peer messaging between the sending node and the receiving node after invalidity is detected or through pre-broadcast of a commit message containing the valid transaction that the receiving nodes may unlock once they have identified the invalid transaction.

Embodiments include but are not limited to: solutions for securing and verifying data, controlling access to controlled resources, proving identity and/or authorisation, implementing agreements between computer-based resources. In an example, a first node (Alice) sends an encrypted challenge to a second node (Bob). The challenge can also be called a puzzle. The challenge has been encrypted using the Bob's public key. Upon receipt, the Bob uses his corresponding private key to decrypt Alice's challenge. This enables him to compute a solution and send it to Alice as proof that he must have decrypted her challenge and must, therefore, have knowledge or possession of the private key. If Bob does not have the private key, he is unable to decrypt the challenge and provide the correct solution. Some embodiments can be implemented using a blockchain for provision and execution of the challenge and/or solution.
