Identifier indicates position of the block in block chain, and block height is since 0.And the block chain that the present embodiment obtains is current
The block height of current most newly generated block in block chain block height namely block chain.In addition, also being needed in the present embodiment
Detection starting point height is obtained, namely local block is detected since detecting starting point height, until detecting described current
Until block chain block height namely current block chain block height is detection terminal height.Wherein detection starting point height can be with
It is set, for example, if desired block all on block chain is synchronized by local data base, is then detected as needed
Point height is the corresponding block height of first block；If local data base only synchronize block chain on newest several blocks or
Newest several blocks are only needed to detect that with the presence or absence of losing, then the range setting detection starting point height detected as needed；It is right
In periodic Detection task, the detection starting point height in this period can be the detection terminal height in a upper period, can will be every
The detection starting point height and detection terminal height in one period are stored in local data base, when the starting of this period from local data base
The detection terminal height in a period in middle reading；In addition, in periodic Detection task, it can also every detection in ergodic process
One block updates one-time detection starting point height, arrives current block chain block height until updating, at this time newest detection starting point
Height is detection terminal height, can be used as the detection starting point height in next period.It furthermore it should be noted that can not also be to work as
Preceding block sequence block height is as detection terminal, but separately setting detection terminal height, namely only detects among local block
Certain blocks are with the presence or absence of loss.It needs constantly to carry out since block is synchronous under normal conditions, the present embodiment is preferably
Using current block chain block height as detection terminal.

Whether block namely block are lost, and can also more specifically detect in a certain block whether have loss of data.
If S103, detecting the presence of loss block, the loss block is obtained from the block chain, and be stored in this area
At the corresponding block height of block.
In the present embodiment, when detecting the presence of the case where losing block, then re-synchronization loss block, namely from area
Block chain reacquires the corresponding block of loss block, and is stored at the corresponding block height of local block.It needs to illustrate
The case where being, block is lost shown in the present embodiment, including entire block are lost, and may include losing number in some block

Periodic cycle executes.Specifically, the current block chain block height of block chain is obtained when the first detection cycle starts, and
Using first block as detection starting point height, to successively traverse in local block from first block to current block sequence
Block between block height is lost block if it exists and is then compensated to loss block；When the second detection cycle starts, obtain
The current block chain block height of block chain at this time, due to having had detected a part of local block in the period 1,
Second round only needs the detection terminal height of then period 1 to continue to test, and also will detect terminal height the period 1
Spend detection starting point height as second round, such as a upper cycle detection to third block, then this period is with third block
Starting point height is detected, the 4th block, the 5th block and subsequent block are successively traversed.Periodic cycle through this embodiment,
The newest local block for being synchronized to local data base is constantly detected to realize, guarantees timely to compensate loss block,
Guarantee the integrality of local block data.
In the present embodiment, ergodic process is specifically as follows:
Block corresponding with the detection starting point height in the local block is detected；
By the detection starting point height, count is incremented if detection block is not lost；If detecting certainly, block is lost,
By the detection starting point height, count is incremented after the re-synchronization loss block；
Circulation executes until detection starting point height reaches the current block chain block height.
In the present embodiment, when detection starting point height reaches the current block chain block height in this period, that is, reach this
The detection terminal in period can be used as the detection starting point height of next detection cycle.
Further, it is successively traversed described in S102 in the local block stored in local data base from the detection starting point
Height arrives the block between the current block chain block height, comprising:
In successively ergodic process, parses and correspond to block in the either block and block chain of local block and compared
It is right, it is judged as loss block if comparison result is inconsistent.
In the present embodiment, in order to guarantee that local block internal data also can be with the inside number that corresponds to block on block chain
According to consistent, therefore local block can be parsed in ergodic process, while parsing and corresponding to block on block chain, compare parsing
As a result, judging that the block internal data goes out active, therefore be also judged as loss block, the area Bing Duigai if result is inconsistent
Block carries out re-synchronization.In the present embodiment, ergodic process specifically can first detect whether a certain block height is sky, if it is empty then
Directly it is judged as that block is lost, carries out re-synchronization；If not empty, then further progress block analysis and comparison, and if block
The parsing result of block on chain is inconsistent, then judges to lose data inside the block, carry out re-synchronization；If not empty, and
Parsing result is consistent, then updates the detection that detection starting point height carries out block height.In the present embodiment, parsing can be solved only
The important information in block, such as Transaction Information are analysed, to improve resolution speed, and then shortens duration used in ergodic process, mentions
High detection efficiency.
Further, the detection process in the present embodiment and the synchronizing process of block do not clash, and can parallel may be used
Serially.Wherein the synchronizing process of block may include the following two kinds scheme:
Scheme one: receiving the synchronization notice that the block chain is sent in newly-increased block, newly-increased block is synchronized to described
In local data base.
In scheme one, using the passively method of synchronization, namely when block chain increases block newly, sent out to local device
Synchronization notice is sent, wherein may include that information, the local devices such as the block height of newly-increased block are logical according to synchronizing in synchronization notice
Know and obtain newly-increased block from block chain, and store into local data base, to realize the synchronization of local block.
Scheme two: the current block chain block height and sheet of the block chain are periodically acquired with the second prefixed time interval
The block chain is obtained current block chain if local block height is less than current block chain block height by ground block height
Block between block height and local block height is synchronized in the local data base.
In scheme two, the synchronizing process of block is realized by timed task, namely at predetermined intervals periodically
The current block chain block height and local block height of block chain are obtained, and judges the current block chain block height of block chain
Size between local block height illustrates if local block height is less than current block chain block height upper one
Secondary completion synchronizes rear block chain and increases block newly, then local device obtains newly-increased block namely block chain obtains current block sequence
Block between block height and local block height, and store into local data base, to realize the synchronization of local block.It needs
It is noted that the second prefixed time interval can it is identical as the first prefixed time interval can also be different, can be according to actual needs
It is set.
