0001 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.

0001 The present invention relates to a method for enhancing the security and integrity of Proof-of-Work (PoW) systems in blockchain networks. Traditional PoW validation relies on verifying a valid nonce, but this approach is vulnerable to manipulation, as it does not independently confirm the entire computational process. The invention proposes a novel solution that securely validates the full PoW computation, ensuring that miners perform the intended algorithmic steps rather than exploiting shortcuts or using nonces derived from different algorithms. By embedding cryptographic proofs within the PoW verification process, the invention prevents tampering and manipulation, enhancing the transparency, security, and trustworthiness of PoW-based blockchain systems. This method strengthens the consensus mechanism and protects the network from malicious actors, ensuring the integrity of the blockchain.
