Algorithm ID when, can specifically be realized by following two mode:
In a kind of embodiment shown, target user, can be by electronics label when issuing object content to block chain
Name algorithm ID is filled in the object content, thus when block chain receives above-mentioned object content, it can be directly out of this target
The algorithm ID of the electronic signature algorithm used when signing electronically to the object content is obtained in appearance.
Wherein, it should be noted that electronics is carried out to the object content when block chain is got from above-mentioned object content
After the algorithm ID of the electronic signature algorithm used when signature, it is based on holding if subsequent above-mentioned target user needs to issue to block chain
The same private key having using it is same electronic signature algorithm signed electronically after object content, then in subsequent issued
In object content, algorithm ID can be no longer carried.I.e. in this application, for the effective private key that user holds,
As long as electronic signature algorithm used by the object content to publication does not change always, then subsequent be based on the private in publication
Key signed electronically after object content when, can no longer need in the object content carry algorithm ID.Certainly, if with
The private key that family is held updates, or the electronic signature algorithm used changes, in the object content of subsequent issued still
Need to carry algorithm ID.In a kind of scene shown, above-mentioned object content specifically can be the target being distributed in block chain

The account address of user and the electronic signature of initiator user；In the output, it will usually carry the bit coin number of this transaction
The account address of amount and recipient.Therefore, in such a case, it is possible to account entrained in input and output
Location format is extended, to carry electronic signature algorithm ID corresponding with account address；For example, initiation that can only in input
Algorithm ID is carried in the account address of square user, can also carry algorithm in the account address of recipient user only in the output
ID, alternatively, in account address in outputting and inputting while carrying algorithm ID.
Certainly, other than except through the mode described above that algorithm ID can be recorded in account address, in reality
In, format can also be issued by the content for the standard supported block chain and be extended, expanded in object content
Then one algorithm id field carries the algorithm ID of electronic signature algorithm used when signing electronically to instruction upper
It states in object content, is distributed to block chain together.
For example, generally including payee address in the transaction content that user issues to block chain, requestee address, being based on
The fields such as the electronic signature of private key submission and public key corresponding with the private key that user holds.It, can be in transaction when realizing
Field extension is carried out on the basis of these information carried in appearance, also regard above-mentioned algorithm ID as an independent field, is carried
In above-mentioned transaction content.In another scene shown, above-mentioned object content is specifically also possible to be distributed to above-mentioned block
The triggering command for the intelligent contract program included in chain.
In this case, recipient's account address of above-mentioned object content, specifically can be the intelligence contract program

Connection is stored in an independent list, can also be from being based on the mesh so that above-mentioned block chain is when receiving above-mentioned object content
The specific information carried in mark content inquires the electronic signature used when signing electronically to the object content from the list
The algorithm ID of algorithm is then based on algorithm ID and further finds out electricity corresponding with algorithm ID in above-mentioned Algorithm mapping table
Sub- signature algorithm.
For example, since user is distributed to the object content in block chain, it will usually carry the public key information of user, therefore can
A mapping table is pre-created, the public key of user and the mapping relations of electronic signature algorithm ID corresponding with public key are stored；Into
And after block chain receives the object content of user's publication, it can read public key from the object content, then will read
Public key searches corresponding electronic signature algorithm ID as search index from above-mentioned mapping table.
In this application, when in block chain any node calculate equipment by search procedure illustrated above, finally look into
It has found when above-mentioned target user signs electronically to above-mentioned object content after used electronic signature algorithm, then it can be with base
Electronic signature in the corresponding public key of private key that the electronic signature algorithm and above-mentioned target user are held, to the object content
It is verified；If the verification passes, then verification result can be broadcasted into block chain, and in the distributed data base of block chain
When generating new block, it is embodied in the new block.Certainly, if authentication failed, the object content will not be broadcasted and
It includes.
After successfully including above-mentioned object content to block chain, the node device in subsequent block chain can be from block chain
Distributed data base in call these object contents included, completing subsequent processing；For example, working as above-mentioned target
Content is the transaction content for being distributed to target account address, after the transaction content is successfully included to block chain, subsequent block chain
In node device can call these transaction contents to carry out transaction verification, and complete after transaction verification passes through this friendship
Easily, transaction results are issued to block chain；For another example, after above-mentioned object content is to be distributed to the triggering command of intelligent contract program,
The triggering command is called and executed to the subsequent intelligence contract program, then issues implementing result to block chain.
By above embodiments as it can be seen that by supporting a variety of electronic signatures to calculate in the decentralization system based on block chain
On the one hand method allows above-mentioned decentralization system to carry out interface flexibility using the system of different electronic signature algorithms；
For example, for the transaction system of the decentralization based on block chain civil for bit coin, ether mill etc.,
If system can support the electronic signature algorithm of the national standard of country variant simultaneously, the electronic signature of national standard can be used
Algorithm verifies the electronic signature in the block chain of the civil transaction systems such as bit coin, ether mill, to allow bit
Electronic signature in the block chain of the civil transaction systems such as coin, ether mill also has legal effect.
On the other hand, it after any one the electronic signature algorithm failure supported in above-mentioned decentralization system, can only make
At the account failure of the electronic signature algorithm using the failure, and can't be to using other electronic signature algorithms not failed
Account impacts, and only supports uniquely to sign electronically after algorithm failure so as to reduce above-mentioned decentralization system, and makes
At whole system collapse risk.
For example, by taking the transaction system for the decentralization built based on block chain as an example, if the system supports a variety of electronics
Signature algorithm, when any of them electronic signature algorithm broken through by hacker after, using it is other electronic signature algorithms account simultaneously
Security risk will not be faced；Moreover, in such a case, it is possible to by using the money in the account of the electronic signature algorithm of failure
Gold is quickly transferred in the account using other electronic signature algorithms, and then the risk for avoiding whole system from collapsing.
