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.

A system, method and process for product authentication and verification using Near Field Communication (NFC) technology, blockchain technology (Hyperledger), and cryptography. A unique product identifier is generated for a unique individual product, incorporated into a data structure, and the data structure is recorded to a blockchain initiating an immutable record for the unique product identifier. An NFC tag is encoded with a tap-unique URL comprising the unique product identifier and a cryptographic output and affixed to the product. Each time the tag is tapped by a proximity coupling device, a web client operating on the proximity coupling device opens the URL whereupon the tag is verified using a cryptographic verification process and generating a verification result. The verification result is recorded on the blockchain ledger for the unique product identifier, thereby creating an immutable record of each tap interaction result.

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 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.
