Optionally, in order to avoid that the method for managing and controlling permissions in the blockchain is damaged by some malicious users, the first transaction may be sent by the administrator user through the client. That is, after creating the starting block, the block chain may set an administrator user, where the administrator user has an authority to set the authority type and the corresponding authority account or change the set authority type and/or the authority account corresponding to the set authority type, and other general users do not have such authority.

S27, the client sends the transaction of the authority account corresponding to the set authority type to the block chain platform;
the transaction of the authority account corresponding to the set authority type can be sent to the blockchain platform by the administrator user through the client.
For example, an administrator user may send a transaction carrying a setting request including an account a, an account b, and an account c for an authority account corresponding to a transfer transaction to the blockchain platform through the client.

each consensus node in the block chain can store the authority account corresponding to the set authority type in a state database in the consensus node. For example, each consensus node in the blockchain may maintain a mapping between the set transfer transaction and the a, b, and c accounts in a status database in the consensus node.
S211, the block chain platform returns an execution result to the client;
for example, the blockchain platform returns the result that the setting of the authority account for the transfer transaction comprises the account a, the account b and the account c to the client successfully.
S212, the client sends a transaction to the blockchain platform, wherein the transaction carries a transaction type and a corresponding transaction account;
for example, the transaction type is a transfer transaction, and the transaction account comprises an account a and an account b.
S213, the consensus node in the block chain checks whether the transaction has the corresponding authority type and authority account.
For example, whether the authority type of the transfer transaction is set or not can be inquired from a state database in the consensus node, when the authority type of the transfer transaction is determined to be stored in the state database, whether the authority account corresponding to the transfer transaction comprises an account a and an account b or not is determined, if the authority account corresponding to the transfer transaction comprises the account a and the account b, consensus operation aiming at the transaction can be initiated in a block chain, and otherwise, a result of transaction execution failure is returned.

Computer-readable media, including both non-transitory and non-transitory, removable and non-removable media, may implement information storage by any method or technology. The information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), Static Random Access Memory (SRAM), Dynamic Random Access Memory (DRAM), other types of Random Access Memory (RAM), Read Only Memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), flash memory or other memory technology, compact disc read only memory (CD-ROM), Digital Versatile Discs (DVD) or other optical storage, magnetic cassettes, magnetic tape magnetic disk storage or other magnetic storage devices, or any other non-transmission medium that can be used to store information that can be accessed by a computing device. As defined herein, a computer readable medium does not include a transitory computer readable medium such as a modulated data signal and a carrier wave.
It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
