Preferably, the names of the new block chains limit the number of words, and provide names that are as compact and as complete as possible.
S102, verifying the request.
Wherein the blockchain supports querying the identification on the blockchain by the number or the name, a result of the querying including at most one of the identifications, the result not being empty indicating that the number or the name is occupied.
When the request is verified, if the number of the new block chain in the request is not empty, the block chain confirms whether the number is occupied, and if the number is occupied, the request is rejected.
When the request is verified, if the name of a new block chain in the request is not empty, the block chain confirms whether the name is occupied, and if the name is occupied, the request is rejected.
Preferably, a cache or index may be provided for the identification on the block chain, supporting more efficient querying, so as to provide efficiency of the block chain out.
Optionally, if the numbers use numbers, the numbers are compared by using the numbers.
Preferably, before the request is created, the number and the name are confirmed to be unoccupied by using a query service provided by the block chain, so that the number of invalid requests can be reduced.
Preferably, the query service provided by the blockchain before receiving the request confirms that both the number and the name in the request are unoccupied, and direct rejection is not satisfactory, so that the number of invalid requests can be further reduced.
S103, the uplink is requested and the identity of the new block chain is generated.
And after the verification is passed, the block chain links the request and generates an identity certificate of the new block chain, wherein the identity certificate comprises at least one of the number of the new block chain and the name of the new block chain.
Wherein the identification is generated from the request.
Preferably, the identification further includes a management account list of the new blockchain, and the management account list of the identification is the same as the management account list of the request. Further, optionally, if the management account list in the request is empty, the account address of the initiator of the request is written into the management account list of the identification.
Preferably, the name of the identification is the same as the name of the request; and if the number in the request is not empty, the number of the identification is the same as the number in the request.
Preferably, if the number of the new block chain of the request is empty, the block chain provides an unoccupied block chain number for the request and writes the identification.
Preferably, if the block chain uses a consensus mechanism such as a practical byzantine fault tolerance mechanism, the identification further includes a signature of the block chain link pointing out the block account.
Preferably, the identity certificate further includes a uplink certificate of the request, where the uplink certificate includes a block header of a block in which the request is located, a mercker certificate of the request in the block, a certificate of the block on the block chain, and the block chain is certified that the request has been linked by the block header and the mercker certificate. Further, preferably, the blockchain provides a service for querying the request.
And S104, creating a block chain by using the identity card.

The new block chain writes the identity certificate into an established block of the new block chain, the new block chain provides the identity certificate, and the identity certificate is completely consistent with a block chain number, a block chain name and a management account list of the new block chain. The new blockchain has unique identity information of the new blockchain, and the identity certificate is provided to indicate the identity of the new blockchain and is accepted when the new blockchain interacts with other blockchains. Therefore, the blockchain has unique identity information, and the user does not need to manually input or distinguish the identity of each blockchain. In addition, the identification does not limit the consensus mechanism, the service range, etc. of the new blockchain, so the blockchain technology used is not limited when creating blockchains.
And if the management account list of the new blockchain is not empty, managing the new blockchain by the account in the management account list.
An embodiment of the present application provides a block chain creation apparatus based on a block chain, including:
