    Abstract: The present invention relates to an implementation method for graphic-blockchain-orientated hybrid consensus, at least comprising: calling at least one module to generate a new data block and broadcast it; calling at least one module to check and validate the received new block based on predetermined rules; calling at least one module to generate a void block; and calling at least one module to update a committee member list. The existing graphic blockchain can only achieve probabilistic consensus, yet the present invention achieves deterministic consensus on graphic blockchain for the first time, thereby reaching consensus faster. The present invention decouples generation and consensus of blocks for the first time, so that the two parts can be designed separately in a modularized manner. The present invention provides the first totally decentralized hybrid consensus algorithm in the graphic blockchain. This is unachievable to many existing graphic blockchain such as IOTA and Obyte.

    Abstract: The present invention relates to a lightweight data storage apparatus for graphic blockchains, at least comprising a common transaction construction module for a user to initiate new transactions and a network broadcast module for broadcasting the transactions, wherein the apparatus further comprises a combined-transaction constructing module and a transaction deleting module, wherein the combined-transaction constructing module serves to determine whether number of transactions initiated by an account satisfies a first predetermined condition, and if yes, execute a first lightening procedure on the transactions, and the transaction deleting module serves to execute a second lightening procedure on the transactions that have been processed by the first lightening procedure and now have validation references satisfying a second predetermined condition, after which the network broadcast module broadcasts the transactions obtained after the second lightening procedure. With the disclosed transaction-combining and reference-transaction-deleting scheme, data storage overheads of a graphic blockchain can be reduced.
