The server-side of X software is triggered to the server-side requested service data of X software with the user terminal of user A below
For identifying code verifying, the above method is illustratively illustrated.
In the present embodiment, the server-side of X software configures in individual centralized server；In another embodiment, X
The server-side of software can be only fitted in the node of the first block chain (be specifically configurable to the contract of the first block chain, can also
To be configured to the local service of the node of the first block chain, etc.), it can also configure and (equally may be used in the node of the second block chain
To be configured to contract or local service etc.).
In the present embodiment, the server-side of X software requires user to provide public key and corresponding address in login account, from
And have each user public key and corresponding address；In another embodiment, the server-side of X software is also configured as requiring to use
The family public key that authorization service end obtains user when carrying out identifying code verifying in login account and corresponding address are, it can be achieved that phase
Same technical effect.
When the user terminal of user A is to the server-side requested service data of X software, the verifying of identifying code is triggered:
In step s 11, the server-side of X software generates first verifying of several characters in response to above-mentioned triggering at random

System is recorded on block chain, and user terminal is allowed to inquire the identifying code of encryption on block chain and by private key for user solution
It is close, and the identifying code that decryption obtains is issued into server-side and is verified, to realize without binding cell-phone number or hardware device
And it is suitable for the identifying code scheme of decentralization system.
Preferably, the first identifying code is configured with the validity period of fixed duration or fixed block height quantity, the validity period
Entry-into-force time is time point or block height of first transaction record on the first block chain.
For example, the first identifying code c1Validity period be configured to 300 seconds or 50 block height, work as tx1The block being packaged is logical
Common recognition is crossed when being recorded on the first block chain, first service end gets time point t1Or the block height h of the block1, first
Identifying code c1It comes into force；
When first service end receives the second identifying code c2Without departing from 300 seconds time (t1+ 300s) or 50 block height
(h1+ 50) when, the second identifying code c2It does not fail, compares c2With c1It is whether identical；
When first service end receives the second identifying code c2Time exceed 300 seconds (t1+ 300s) or 50 block height (h1+
50) when, the second identifying code c2It has been failed that, authentication failed.
