Abstract

A complex cryptographic coinage transaction is transactionally sharded into multiple simple cryptographic coinage transactions. The complex cryptographic coinage transaction specifies cryptographic debits and/or deposits to/from multiple input accounts and/or multiple output accounts. The simple cryptographic coinage transactions, however, only specify a single one of the input accounts and/or a single one of the output accounts. A single server within a blockchain environment may thus process one of the simple cryptographic coinage transactions without requiring calls for data from other servers responsible for other accounts.

Core Innovation

A sharding server in a sharded blockchain receives a blockchain-based cryptographic coinage transaction conducted via an internet between a set of computers. The sharded blockchain includes a plurality of blockchain shards, where each blockchain shard is configured to process a different set of simple cryptographic coinage transactions. The sharding server determines whether the received blockchain-based cryptographic coinage transaction is a complex transaction.

When the received blockchain-based cryptographic coinage transaction is determined to be a complex transaction, the sharding server transactionally shards the complex transaction into multiple blockchain-based simple cryptographic coinage transactions. Each simple cryptographic coinage transaction is either a debit transaction specifying a temporary account address and an input account address, or a deposit transaction specifying the temporary account address and an output account address.

The sharding server assigns each blockchain-based simple cryptographic coinage transaction to a corresponding blockchain shard for processing and transmits debit transactions to the debit-transaction corresponding blockchain shard for debit processing. The sharding server determines that all debit transactions debit-processed successfully, and in response, transmits each deposit transaction to the deposit-transaction corresponding blockchain shard for credit processing. The processing is positioned as enabling a single server to process components without cross-server data dependencies while maintaining compatibility with blockchain consensus and cryptographic verification.

The described approach further covers recording and processing of the simple transactions on-chain, fee handling tied to the sharded components, temporary account usage and failure/refund behavior via the temporary account address. It additionally includes cryptographic hold orders with timing constraints to prevent overdrafts, optional look-ahead prediction of success/failure, and indexing of simple transactions including generation of cryptographic balance sub-proofs. Integration with a cloud/blockchain data layer is described using hashing/Merkle proofs and public anchoring.

Claims Coverage

The independent claims cover three aspects: a non-transitory memory device for sharding-server execution, a sharding-server system for performing the same workflow, and a method implementing the workflow. The inventive features are the transaction classification as complex, transactional sharding into debit and deposit simple transactions using temporary account address roles, shard assignment with ordered debit-before-deposit conditional processing, and dependent refinements including recording, follow-on cryptocoinage transacting, and cryptographic coinage holds with time-based expiration.

Across the independent claims, the core inventive coverage is the detection of complex cryptographic coinage transactions, their transactional sharding into simple debit and deposit transactions using temporary account address roles, and shard assignment with conditional ordered execution where deposit processing is transmitted only after successful debit processing. Dependent claims further narrow the scope by adding recording, follow-on cryptocoinage transacting, and cryptographic coinage holds with time-based expiration on input account addresses.
