Methods, devices, and a data structure for processing large volumes of transactions in blockchain nodes without using a mempool. Incoming transactions are validated and added to a candidate block. Transaction identifiers are added to an ordered set of transaction identifiers in an array until complete. The completed array and its Merkle root are propagated to other nodes. A placeholder transaction may be used in the first array in place of a coinbase transaction and its Merkle path may be determined to enable replacement of the placeholder transaction by the coinbase transaction during mining. Subsequent arrays are appended to the consolidated list of transaction identifiers are they are completed to continuously build a growing candidate block for mining.

The present disclosure provides methods and systems for distributed and/or parallel processing of data records, and in particular mining of blockchain transactions in a blockchain block, and further still for generation of a Proof-of-Work (PoW) for a blockchain block. Advantageously, embodiments allow for separation of the PoW calculation from other blockchain mining/validation tasks. Preferably, a PoW requester sends a specialist PoW provider one or more of: i) a Merkle root for a Merkle tree that represents a set of transactions ii) a control transaction (TX0) and iii) a Merkle proof which confirms that TX0 is included in the set of transactions. TX0 may provide or comprise control data that the PoW provider can use to determine whether or not performance of the PoW calculation is to be performed or completed.

Embodiments disclosed herein describe a proof of majority block consensus method based upon a mutually enforced collaboration between the nodes. A node may maintain a random subset of connected peer nodes, refreshed at every epoch through network gossiping protocols. The node may propagate received transactions to selected peers in the random subset. The node may generate a transaction ballot from received transactions and iteratively update the transaction ballot by mutual exchanges with other nodes until the network converges. The node may generate a block- and a hash thereof-based upon its understanding of the transaction ballot. The node may also receive hashes from other connected nodes and identify a hash generated by the majority of peer nodes. If the node determines that its own hash is the one generated by the majority of peer nodes, the node may update its local copy of the blockchain by appending its block.

The invention provides improved methods and corresponding systems for the sharing, storage, creation and accessing of data stored on a blockchain e.g. the Bitcoin blockchain. It may form part of a protocol for searching the blockchain for content/data. A method in accordance with the invention may be used for associating or linking data stored within (separate/different) blockchain transactions to enable the identification, retrieval and/or sharing of data stored therein. Additionally, or alternatively, it facilitates identification of transactions (TX) in a blockchain which store content/data that needs to be shared, transmitted, stored and/or accessed by a user. Such a method comprises the step of mapping a mnemonic to: 1) a public key (PK) associated with the transaction (TX); and 2) the transaction ID (TXDD) of the transaction (TX).

Resumen de: AU2023364152A1
Methods and systems are presented for providing a token exchange framework that enables exchanges of reward tokens corresponding to different reward systems and/or different merchants. The token exchange framework includes a blockchain for storing transaction data associated with transactions of reward tokens. During the onboarding process, reward systems associated with different merchants may be connected to the blockchain of the token exchange framework via one or more bridges. Reward tokens may be issued to represent reward data corresponding to the different reward systems, and can be freely exchanged within the token exchange framework via the blockchain. When a transaction for redeeming a reward is received, reward tokens in the blockchain can be converted into reward data corresponding to the merchant's reward system and process the transaction with the merchant using the converted reward data.

A network-based service creates a smart contract on a blockchain on behalf of a user who has a loan or a subscription that requires installment payments be collected by a provider from the user and provided to creditor of the loan or subscription. The smart contract associates a default account of the user with a first access token and non-default registered other accounts of the user with a second access token. The smart contract when presented with the access tokens from a provider determines whether the payment due can be satisfied from a current balance of the default account and if so, transfers the payment from the default account to the provider. If the default lacks sufficient funds for the payment, the smart contract proportions the amounts taken from each of the accounts to reach the amount due and transfers the amount due to the provider.
