The table name of storehouse table, the basic cryptographic Hash that corresponding value is generated in the step S2 comprising first embodiment.The map tables can be deposited
Storage is in local caching.
Step A2, when a certain transaction node sends a transaction to the block catenary system, first in the local map
Inquired about in table.
The first situation, step A3, if can be found in the map tables, with the basic cryptographic Hash that this is cached, makees
For newest basic cryptographic Hash, subsequent operation is carried out as in the first embodiment.
Second of situation, step A4, failing to find, then the transaction node is to the block catenary system acquisition request
The basic cryptographic Hash recorded in the object of the database table, as newest basic cryptographic Hash, enters as in the first embodiment
Row subsequent operation.
Preferably, in the latter case, the transaction node with the basic cryptographic Hash obtained from block catenary system come more
Value in the new local map tables.

Formula.
Step A5, (the cryptographic Hash verification such as the step S5 of first embodiment of transaction after the transaction success of transaction node
It is described), the transaction node updates the value in the local map tables.
In the present embodiment, map tables locally are being set up, because, it is general in the block catenary system based on database
(such as 3~9 seconds) can just generate a new block at regular intervals for setting, and the attribute of database table is all recorded in block
On, therefore the change of basic cryptographic Hash could be only reacted on new block.So, if in this time (trade fair quilt
Note is on a block) inner want to send multiple transaction to operate the table, it is necessary to a basic cryptographic Hash is cached to safeguard transaction
In the continuity of cryptographic Hash that records.
On the other hand, because the map epitopes are in caching, then the map tables can not be allowed constantly to increase, therefore, in step
A6, is that the database table in map tables sets up timer, if in a period of time (such as 30 minutes), a certain number in map tables
Do not change, then deleted in the map tables to the basic cryptographic Hash of the database table according to the clocking information of storehouse table cache
Caching record.
In addition, when the basic cryptographic Hash of certain database table in the local map tables in block catenary system with recording

Merchandised to one or more operations for a same database table.Need to perceive this mistake in time and correct this node
Corresponding basic cryptographic Hash in caching.
To all it recorded in the map tables local above by the transaction for some database table of this node, often
Generate a new block, local node check each database table recorded in local map tables operation whether into
Work(is recorded on block, if on record, deleting corresponding transaction, if it find that not recorded on block, then deleting
All Activity (because being all based on a wrong basic cryptographic Hash) after this transaction, then goes in block chain to go to obtain again
The basic cryptographic Hash of newest normal corresponding table is taken, the basic cryptographic Hash in the map tables of local cache is updated.
