Optionally, in a scenario of data storage, etc., no uplink data is additionally generated when the document is processed, so that the transaction is only added to the block, and no other uplink data to be linked is to be linked.
Preferably, if the uplink data relates to the status of account amount, etc., then to update the status data of the block chain, the rest is directly written into the block to be linked together with the transaction.
In this embodiment, the document template of the blockchain system is used to process transactions, so as to ensure that the uplink transactions meet the data standard in the corresponding document template, so that the data on the blockchain is standardized, and the target chain can directly know the meaning of the data when the transaction data on the blockchain is cross-linked to other blockchains, without additional processing.

In fact, any blockchain cannot be an island, and each blockchain creates its own data and depends on data provided by other blockchains. As blockchains become more popular, cross-chain requirements between blockchains increase, and many cross-chain requirements are duplicative or similar jobs that may use the same data standards, as are the various document standards in EDI.
Through the block chain system, the transaction processing method and the device provided by the invention, on one hand, a document template is established according to a data standard, a document generated by using the document template meets the data standard, a transaction consisting of documents also refers to the data standard, and the document template is used for processing the contained document before the transaction is linked, so that the data standardization work on the block chain is completed; on the other hand, the authorization mechanism ensures the original document template, helps developers to obtain benefits from the work of developing the document template, encourages the development of richer document templates, and is beneficial to the ecological construction of the whole block chain.
