As shown in Fig. 2 the present invention is comprised the following steps：
（1）A constant of 160bits is directly specified as public key；Constant can have 160 0,160 1 or by 0,1 by rule
Rule composition.Four high of such as each byte be 1 low four for 0 20 numerals of byte：
1111000011110000111100001111000011110000111100001111000011110000111100001
11100001111000011110000111100001111000011110000111100001111000011110000111100
0011110000；
It is in turn then unworkable by public key Hash calculation public key due to the only unidirectional computing of SHA256 and RIPEMD160 algorithms
's；（2）The address version number of one byte is connected to public key Hash head（Version number can select 0- by block chain formulation side
Any Digit between 255）, SHA256 computings twice then are carried out to it, using verification of 4 bytes as public key Hash before result
Value, is connected to its afterbody；（3）By step（2）The result for obtaining is encoded using BASE58, has just obtained block chain assets
Destroy address（An address without known private key and public key is calculated as shown in Figure 2, and this address institute correspondence that may be present is private
Key is the one of 2 160 powers point）；
（4）Digital asset is transferred in the block chain asset addresses for obtaining（Destroy address）, due to for consuming digital money
Not with known private key, public-key cryptographic keys to deriving, because without private key, this part assets is cannot be by for the address of product
Employ, equivalent to destroyed.
After this transaction address without private key is arrived in transaction in assets book keeping operation, because without private key, wanting to reuse or moving
Can not possibly occur with this side transaction.Even if wanting to calculate private key by Brute Force, wherein also need to by SHA256 and
RIPEMD160 Hash calculations twice.Therefore in the case where existing block chain data structure and book keeping operation mode is not changed, can be by
After assets are transferred to this without private key address, even if all supercomputers in the whole world are added up being also required to tens thousand of years, quilt
The assets voucher for being transferred to this address is equivalent to destroy, and nobody can be continuing with.
